Each electric utility has a department called Resource Planning. They are responsible for what is called an \u201cIntegrated Resource Plan\u201d which is filed usually every 1-3 years with the Public Utility Commission which is the State regulatory body overseeing the utility. In this resource plan they forecast demand for electric vehicles based on the current economic conditions, federal regulations, EV sales, etc. Based on this forecast, a department called Generation Modeling plans for how much generation is needed to meet this new demand. These resources can be new power plants as well as programs called demand side management where utilities give incentives to curb usage during peak times where the system is likely to brown\/black out. These incentives can be based around rate design where the price is cheaper during off peak hours (10pm-5am). Or they can apply to large industrial customers that get a cheaper rate all the time but can have their service interrupted at times of peak demand. TLDR: electric utilities are forecasting the demand for EV vehicles and are planning for this demand by either building new power plants or designing programs to reduce demand around peak hours.","human_ref_B":"A 100% switch to electric vehicles isn't happening overnight.

Also, I imagine it\u2019s something that goes up each year, as populations and global warming both increase. Many people would be charging their EVs at night while sleeping, when it\u2019s cooler and less ACs, lights, etc are running. The charging rates can be adjusted on most vehicles, so they can use less wattage than an AC.

The short answer is, yes. Probably. The history of taxes (especially in the US) is a fraught one, but it really can be divided into two eras: pre-Reagan, and post-Reagan. It's not a case of Democrat or Republican, no matter who might tell you otherwise. Tax rates reached their peak under Eisenhower, and they were lower under Clinton and Obama than they were for six out of Reagan's eight years in office. Historically speaking, it's important to note that current top tax rates are **not normal**. Between the start of WWII and the Reagan Administration, the top tax bracket never dropped below 70%; since 1987, it's never risen above 40%. Why? Well, it mostly boils down to trickle-down economics -- the belief (for better or for worse) that cutting taxes on the top earners will allow them to invest their money more freely, thus providing jobs down the line. As an economic theory, it's pretty flawed, not least because it assumes that the rich *will* reinvest their money, rather than squirrelling it away, as is often the case; if you want money put back into an economic system, it works better to give it to the poor, because they pretty much *have* to spend it. (Sidenote: 'trickle-down economics' is a branding nightmare to begin with, but it was originally known as 'horse and sparrow' economics -- the theory being that, 'if you feed the horse enough oats, some will pass through to the road for the sparrows'. It's got its detractors, is what I'm saying.)

Under Reagan's plan, someone earning the median individual income in 1988 ($25,872) would have paid about 19% in tax. Someone earning the same amount just two years earlier would have paid just 13.8% of his income in taxes. Compare that to someone earning $250,000, on the other hand: he would have paid about 27.7% in 1988, but 41.9% two years earlier.

Following WW2, the two main parties, Labour and the Conservatives, agreed on major policies in a consensus known as Butskellism, named after the Conservative Rab Butler and the Labour leader Hugh Gaitskell. This consensus basically followed the economic theory of Keynesianism which is that idea that the aim of the state should be to keep unemployment as low as possible and the best way to run the economy was to borrow to invest. Part of this theory was substantial high taxes on the wealthy which also helped pay for Britain's extensive welfare state and the sluggish economic situation at the time. This consensus lasted until 1979 when Margaret Thatcher came to power and established a new consensus following monetarist policies. This is similar to \"Reaganomics\" in America. She, and Reagan, believed that individuals spent their money better than the government and so reduced taxes. She reduced the top rate of tax from around 83% to 40% in her first term and it's been like that ever since.

Expenses are essentially a tax write-off because they wash out profit. Let's say you've got a 95% tax on profit over a million dollars. Every business will do their best to keep their profit as close to a million dollars as they can and not go over. This means they spend money to grow. They're more willing to increase salaries to attract talent because where's the money going otherwise? The government. So they build new factories, they pay the average worker better, they develop new products. Why? Because they'd rather write-off money and put it back into the business, thereby increasing their overall value without losing money to taxes. The American economy failed after Reagan because they removed these high end taxes that were forcing businesses to make long term value-increasing decisions. Now people just buy a business, sell off assets, make a boatload of short term money, get their golden parachute because now the goal is to make as much short term cash as possible. They pay people as little as possible now because they don't lose the money to taxes if they keep it. I don't care about being socialist or being capitalist, I'm a functionalist. Does it work? Yeah? That's how we should do it, so understand I'm not approaching this from any particular ideology other than the 90% tax fucking worked for our economy and for the growth of the American dream. We want shit to start working again? Implement that tax. Edit: I... uhh... thanks for the gold! Edit 2: Lots of people asserting how wrong I am. It depends how you measure the success of an economy. I suppose there are some problems with the idea too, but there's also a lot of history and modern examples showing that a super high tax rate on super high end income works pretty fucking well (again, *works* is relative to how you view\/measure success in the first place, if you masturbate to really big profit reports, you'll hate the idea, if things like wealth inequality bother you, you'll probably like it.). See: America in the 1950s, Scandinavia today with strong middle classes. I know there's a *lot* more nuance and complexity that made\/makes those economies and tax structures work\/necessary. Reddit isn't usually a great place for complexity and nuance, thus the nature of my post. I also should note I had had a few beers when I wrote it, so maybe it isn't very well described or is abrasive, and it doesn't really answer the original question that I was responding to very well.

You get deductions and exemptions that cut it down and, oddly enough, the more you make, the more exemptions there are (because people who earn a lot often have complex financial situations). So your 95% rate (which isn't \"one for you, 19 for me,\" as George sang) would maybe end up a third of that. if the Beatles didn't have tax experts working on their behalf, I would be very surprised. George Romney, back in the days of the 71% top rate here in the US, paid something in the mid-30s, percentage wise. His son, at the 39.5% top rate, paid somewhere in the teens.

There are a multitude of factors which I'm not really qualified to try to Explain like I'm five years old, but basically when you're young the body is more resilient to problems so that you can have a baby, and then it doesn't maintain those processes as well later on in time. These factors are the Hallmarks of Aging: https:\/\/en.m.wikipedia.org\/wiki\/Hallmarks_of_aging) For the telomeres, they're basically \"extra DNA\" tacked onto the end of each DNA strand since every time DNA is copied, it can't copy a little part of the end (due to some underlying molecular biology stuff). There's a thing called \"telomerase\" which could tack on more of this \"extra DNA\" to lengthen the telomere occasionally. But, even if we kept the telomeres by using telomerase, we still ultimately suffer from cancer since that DNA we've been maintaining using the telomerase still eventually gets damaged somewhere in the _middle_ either by radiation or some other causes. The longer we live, the more DNA damage we can accumulate like this, and the more cancerous potential we have. In general, the human body's immune system and other things that keep it going are not sufficiently maintained the older we become, for reasons I'm not familiar enough to describe myself. This leaves us continually more susceptible to heart disease, cancer, and general pathology until we succumb to one of these ailments.

It is not possible to copy from the very begining so they need some sort of dead space where the copying can start from.

Blackjack has a memory unlike other games. Big cards good, small cards bad. 5 year-olds shouldn't gamble anyways. Source: former casino employee and card counter. I'll start with some terms here: House edge: expressed in a percentage. The money the house expect to win on each bet. Basic stragety: a tested theorem that that dictates a players move in a given blackjack hand. Please Google basic strategy, there's a neat color coded chart you can look at. Units: the number of increments of the minimum bet that the table maximum will allow. For example, if you are on a $5 minimum BJ table with a limit of $250 that only allows you to play one hand you can bet 50 units. House edge is a representation of the mathematical advantage that the house has built in its rules.. Here are some examples. Roulette: straight up bet pays 35 to 1. I'd you win you get 35 plus your bet. There is 1 way to win, and on a double 0 wheel, 37 ways to lose. If you cover every number (stupid) you lose 38 and win 36. So your return is 36\/38. That's 94.7% return giving the house an edge of 5.3% Craps: betting on a hop (one roll bet) pays to 30 for 1, 30 to 1, 15 for 1, or 15 to 1. Deference here is academic in this case, most casinos only for one, but to one is better. The 30s are for pairs (hard ways). Let's say you think 11 will come next roll. There are 2 ways to roll 11, 6-5, and 5-6, if you have problems seeing this, pretend the dice are different colors. 2 dice x 6 sides = 36 combos. You have 2 ways to win out of 36. Or, 1 in 18. This bet at best pays 15 to 1. So win 16, lose 18. That's an 88.8% return giving the house an edge of 11.2%. SERIOUSLY, I KNOW HOP BETS SUCK. THIS IS AN EXAMPLE OF HOUSE EDGE. Bet the pass line with 10x odds. Happy? The edge represents the difference between the true odds vs payable odds. With me so far? Here's where things change. In all other games of \"chance\", these odds never change. Two dice always roll 11 with the same 2\/36 chance, number 21 comes up approximately 1 out of 38 times in roulette. This is inescapable. Short term variance is expected and even necessary, no one would play a game where they always lost. But blackjack and it's variants (of the non continuous shuffle variety) are different fundamentally, they have memory. There a finite number of cards in that games universe if you will. In a 6 deck shoe (suits don't matter in BJ) there are 312 cards. 24 of each A-9, and 96 10 value cards (10, J, Q, K no difference between these functionally) Basic strategy is a statistical model that, based on the rules of the casino at which you are playing, help you make the least bad decision. I say least bad, because it is accurate. There are no good decisions in blackjack because statistically it is still a negative expectation game. Meaning, over a large sampling, with perfect basic strategy, you will still lose. Now, this is for everyone in the back, STATISTICAL OUTCOMES HAVE NOTING TO FUCKING DO WITH SHORT TERM SUCCESS OR FAILURE!!!!!! So, a recap here. Most games suck because the odds are bad and built in. You can chose less bad bets, but all bets are bad, get it? But wait, you said Black Jack is different! It is. As I said, basic strategy lets you make the least bad decisions. Some situations actually have a positive expected outcome, like doubling down when you have 11 vs a dealers up card of 6. Keep in mind though, that the aggregate of all those situations still places you in the territory of negative expectation. Card counting: there are plenty of tutorials online to teach this, but as a very simple rule of thumb, because of the rules of hitting and staying that casinos follow for their dealers, big cards favor the player, while little cards favor the dealer. I'm not going to get into the math here, it's rather lengthy, but suffice to say that knowing the ratio of big cards to little cards remaining in the deck can offer an advantage to the player. So, why does the dealer have the advantage on black jack? It's not their hit\/stand rules. Those only exist because if they were any more lenient to the dealer no one would play. THE ONLY ADVANTAGE THE HOUSE HAS IN BJ IS THE DOUBLE BUST LOSS. Scenario 1. Player has 20, dealer busts. Player wins Scenario 2. Player has 20, dealer has 20. Player pushes (ties) nobody loses\/wins Scenario 3. Player busts his hand, dealer has 20. Dealer wins. These all seem fair so far. Here's the one that earns all the house it's money. Scenario 4. Player busts his hand. Dealer busts his hand. Player still loses. That's it. They only advantage. So, try not to take hits that can bust you unless you statistically need to. Let's now regroup. 1. You know that busting loses your money, though paradoxically, standing when you should hit, while reducing your bust %, actually lowers your statical overall win % more. 2. You know that because 10s are good for you and little cards are bad, if you can keep track of the ratio of that and are in the right situation, you can have an advantage over the house. The average difference in expressed advantage generally is only 2%. Let's say the house has a 51-49 advantage over you, sometimes you can make that 51-49 in your favor with counting. How do you take advantage of this? Unit betting. Let's take a $5 dollar table. It has 7 spots. You are the only player. It's max is$ 500. This casino let's you play all 7 spots if the table is empty. Therefore, the unit spread is as follows 500\/5 = 100 units per spot *7 spots = 700 unit spread. (This is an example only, doing this will get you labeled as a counter on the spot and backed off immediately) As you know the deck (shoe) favors the dealer most of the time it makes sense to expose the least amount of your money to that negative expectation. When the 10 ratio changes in your favor, you can now expose 700 times that bet to a positive outcome. So while you're only going to have a %2 advantage, you're now betting 3500 with a better than even chance of winning. (YES I KNOW THINGS GET STREAKY SOMETIMES. SHUT UP, THESE ARE BASICS. GO FIND SOME COUNTING SUB REDDIT) So, get it? Expose less of you money when you're at a disadvantage and more when it's in your favor. Counting is the exact reverse of the casino model. You're eking out wins on a small marking, but unlike the casini, you can alter your betting and actions with this knowledge TL;DR. yes, blackjack is the a beatable game, but only if you're a card counter. P.s. baccarat. Yes, it is a coin flip. And yes, I've heard of a way to count it. Here the only situation I know of where it can be counted. At the beginning of the shoe, the dealer reveals the first card and burns that many cards. If you can keep track of the 10s in the shoe, and this count of remaining 10 in the deck is equal to burn cards plus the remaining cards in the deck after the cut card is pulled out, theoretically you could guarantee a tie bet, but I'd be willing that this is sore rare in practice, you're better off just studying something useful and getting a career change or a promotion. Sorry about the spelling, this is a long comment for a phone and my dog has been licking my face Edits: edited for grammar and spelling, as well as an expanded craps section because some random craps player thinks he knows what's going on and was confused. As always first reddit gold, thanks so much. Also, for people saying poker, pai-gow, video poker, craps! I try not to talk about thing I don't know much about, but here: 1. Poker is beatable if you're good.or with weak players. 2. No commission pai-gow that let's you bank every other hand is probably close to 50-50. Don't know for sure, check the math. 3. Apparently you can count baccarat, just got a link to look at. 4. Yes, some video poker offers an advantage. Google it 5. Yes, crops has some good bets. Pass with 10x odds is like .43% house edge or something stupid small. Still not 0 6. Advantage play tons of advanced techniques like shuffle tracking, hole tracking, taking advantage of weak delaers, sure that may make a game beatable. YMMV","human_ref_B":"Blackjack is the only game who's outcome is dependent upon past actions. Like, once an ace is played and discarded players know that ace is gone and won't be seen again. Keeping track of what cards have been played can give a player good prediction of what will come up. Knowing that they can adjust their bets so they win big when odds are good and loose little when odds are bad. Casinos fight against this by using multiple decks of cards, re-shuffling at random times, and good old intimidation. \"Card counting\" (the simple process of keeping track of what's been played and understanding current odds) mathematically gives a player a 0.5% advantage over the house. Some say it's as high as 1%, some say 0.1%. But, no matter what, it won't make you rich over night. To see a 0.5% advantage pay off you'll have to play a lot and over a significant amount of time. Those who did get rich with card counting did it with a team. And, don't forget, casinos can ask anyone to leave for no reason at all. If you're statistically winning more than you should, you may get a tap on your shoulder. So, mathematically, yes, you'll have an advantage in blackjack because it is a continuing, past dependent, outcome. But, in real life, you simply won't be allowed to sit at a table and take the Casino's money.","labels":1,"seconds_difference":5666.0,"score_ratio":4.7677902622} +{"post_id":"4y9gz3","domain":"explainlikeimfive_test","upvote_ratio":0.84,"history":"Explain like I'm five years old: Why is Blackjack the only mathematically beatable game in casino?","c_root_id_A":"d6m1p3r","c_root_id_B":"d6m5opa","created_at_utc_A":1471485089,"created_at_utc_B":1471491296,"score_A":535,"score_B":3819,"human_ref_A":"Blackjack is the only game where the odds change.

In a 6 deck shoe (suits don't matter in BJ) there are 312 cards. 24 of each A-9, and 96 10 value cards (10, J, Q, K no difference between these functionally) Basic strategy is a statistical model that, based on the rules of the casino at which you are playing, help you make the least bad decision. I say least bad, because it is accurate. There are no good decisions in blackjack because statistically it is still a negative expectation game. Meaning, over a large sampling, with perfect basic strategy, you will still lose. Now, this is for everyone in the back, STATISTICAL OUTCOMES HAVE NOTING TO FUCKING DO WITH SHORT TERM SUCCESS OR FAILURE!!!!!! So, a recap here. Most games suck because the odds are bad and built in. You can chose less bad bets, but all bets are bad, get it? But wait, you said Black Jack is different! It is. As I said, basic strategy lets you make the least bad decisions. Some situations actually have a positive expected outcome, like doubling down when you have 11 vs a dealers up card of 6. Keep in mind though, that the aggregate of all those situations still places you in the territory of negative expectation. Card counting: there are plenty of tutorials online to teach this, but as a very simple rule of thumb, because of the rules of hitting and staying that casinos follow for their dealers, big cards favor the player, while little cards favor the dealer. I'm not going to get into the math here, it's rather lengthy, but suffice to say that knowing the ratio of big cards to little cards remaining in the deck can offer an advantage to the player. So, why does the dealer have the advantage on black jack? It's not their hit\/stand rules. Those only exist because if they were any more lenient to the dealer no one would play. THE ONLY ADVANTAGE THE HOUSE HAS IN BJ IS THE DOUBLE BUST LOSS. Scenario 1. Player has 20, dealer busts. Player wins Scenario 2. Player has 20, dealer has 20. Player pushes (ties) nobody loses\/wins Scenario 3. Player busts his hand, dealer has 20. Dealer wins. These all seem fair so far. Here's the one that earns all the house it's money. Scenario 4. Player busts his hand. Dealer busts his hand. Player still loses. That's it. They only advantage. So, try not to take hits that can bust you unless you statistically need to. Let's now regroup. 1. You know that busting loses your money, though paradoxically, standing when you should hit, while reducing your bust %, actually lowers your statical overall win % more. 2. You know that because 10s are good for you and little cards are bad, if you can keep track of the ratio of that and are in the right situation, you can have an advantage over the house. The average difference in expressed advantage generally is only 2%. Let's say the house has a 51-49 advantage over you, sometimes you can make that 51-49 in your favor with counting. How do you take advantage of this? Unit betting. Let's take a $5 dollar table. It has 7 spots. You are the only player. It's max is$ 500. This casino let's you play all 7 spots if the table is empty. Therefore, the unit spread is as follows 500\/5 = 100 units per spot *7 spots = 700 unit spread. (This is an example only, doing this will get you labeled as a counter on the spot and backed off immediately) As you know the deck (shoe) favors the dealer most of the time it makes sense to expose the least amount of your money to that negative expectation. When the 10 ratio changes in your favor, you can now expose 700 times that bet to a positive outcome. So while you're only going to have a %2 advantage, you're now betting 3500 with a better than even chance of winning. (YES I KNOW THINGS GET STREAKY SOMETIMES. SHUT UP, THESE ARE BASICS. GO FIND SOME COUNTING SUB REDDIT) So, get it? Expose less of you money when you're at a disadvantage and more when it's in your favor. Counting is the exact reverse of the casino model. You're eking out wins on a small marking, but unlike the casini, you can alter your betting and actions with this knowledge TL;DR. yes, blackjack is the a beatable game, but only if you're a card counter. P.s. baccarat. Yes, it is a coin flip. And yes, I've heard of a way to count it. Here the only situation I know of where it can be counted. At the beginning of the shoe, the dealer reveals the first card and burns that many cards. If you can keep track of the 10s in the shoe, and this count of remaining 10 in the deck is equal to burn cards plus the remaining cards in the deck after the cut card is pulled out, theoretically you could guarantee a tie bet, but I'd be willing that this is sore rare in practice, you're better off just studying something useful and getting a career change or a promotion.

Basic stragety: a tested theorem that that dictates a players move in a given blackjack hand. Please Google basic strategy, there's a neat color coded chart you can look at. Units: the number of increments of the minimum bet that the table maximum will allow. For example, if you are on a $5 minimum BJ table with a limit of $250 that only allows you to play one hand you can bet 50 units. House edge is a representation of the mathematical advantage that the house has built in its rules.. Here are some examples. Roulette: straight up bet pays 35 to 1. I'd you win you get 35 plus your bet. There is 1 way to win, and on a double 0 wheel, 37 ways to lose. If you cover every number (stupid) you lose 38 and win 36. So your return is 36\/38. That's 94.7% return giving the house an edge of 5.3% Craps: betting on a hop (one roll bet) pays to 30 for 1, 30 to 1, 15 for 1, or 15 to 1. Deference here is academic in this case, most casinos only for one, but to one is better. The 30s are for pairs (hard ways). Let's say you think 11 will come next roll. There are 2 ways to roll 11, 6-5, and 5-6, if you have problems seeing this, pretend the dice are different colors. 2 dice x 6 sides = 36 combos. You have 2 ways to win out of 36. Or, 1 in 18. This bet at best pays 15 to 1. So win 16, lose 18. That's an 88.8% return giving the house an edge of 11.2%. SERIOUSLY, I KNOW HOP BETS SUCK. THIS IS AN EXAMPLE OF HOUSE EDGE. Bet the pass line with 10x odds. Happy? The edge represents the difference between the true odds vs payable odds. With me so far? Here's where things change. In all other games of \"chance\", these odds never change. Two dice always roll 11 with the same 2\/36 chance, number 21 comes up approximately 1 out of 38 times in roulette. This is inescapable.

YMMV","human_ref_B":"Let me clear up some misconceptions in this thread. Credentials: Professional poker player in Las Vegas for 9 years. Not a card counter but know plenty who do (or did). 1) Perfect basic strategy without counting + good house rules gets you very close to 50% equity. It's over 49%. This is reduced significantly by bad house rules (ie pay 6:5 on blackjack). You cannot get over 50% without counting and properly adjusting your bets based on the odds for that hand. 2) Part of why you can beat blackjack is the \"history\" as has been mentioned. The other part is the ability to bet SIGNIFICANTLY more when you have an edge vs when you don't. Betting $10 many times as 49.8% dog, and then $50 or $100 a few times as a 54% favorite, will yield positive equity and thus profit in the long run. 3) Blackjack is still very beatable, but casinos have gotten much smarter over the years. The rules are generally worse and favor the house more than in years past. They're better at spotting counters and teams. I know a number of people who have made significant money (well into 6 figures) by counting, and have subsequently been banned or flat bet. It's a good way to make short-term money if you know what you're doing, but you need a significant bankroll as the swings can be enormous. 4) Assuming you're not counting, then other players playing correctly or incorrectly will NOT affect your equity. Someone hitting when they should stay is just as likely to help you as hurt you, so leave them alone and let them do as they please. Anyone saying otherwise does not understand statistics. EDIT TO ADD 5) Some comments have mentioned poker, sports betting, horse racing, and certain video poker \/ slots as other profitable opportunities if you know what you're doing. Poker is obviously true, as many people make their living playing poker. The key difference is that you play against other players and simply pay the casino a flat rate, so they don't care if you win. Literally thousands and probably tens of thousands of people around the world make their living playing poker, both in casinos and online. Sports betting is true, although it takes a lot of work and very good computer models to beat it. Also never, ever, ever pay for a tout service to give you picks. 100% of them are scams. Horse racing I'm honestly not sure about, as I know next to nothing about it. But I've been in Vegas a long time and have never met someone who is a professional horse bettor. Anecdotally, everyone in that section of the sports book looks like a degenerate (or someone just having fun on vacation). But maybe? If anyone knows more I'd like to hear. Video poker \/ slots is also true under certain circumstances. Some of the progressive jackpot slots can actually be pretty lucrative when the jackpot gets big enough, but it's an enormous time sink and requires an enormous bankroll. I know people that have tried to take advantage, and they give up after not too long. The edge on profitable video poker machines is small and you're not going to make any significant money grinding those. Minimum wage maybe. People who are VERY good at heads up limit holdem can beat the poker machines (NOT video poker, but actual poker played against an AI). The AI is awfully good though, and will absolutely obliterate a random tourist. They put these things outside of poker rooms and they must absolutely print money on them to an absurd degree.","labels":1,"seconds_difference":251.0,"score_ratio":28.2888888889} +{"post_id":"4y9gz3","domain":"explainlikeimfive_test","upvote_ratio":0.84,"history":"Explain like I'm five years old: Why is Blackjack the only mathematically beatable game in casino?","c_root_id_A":"d6m1vmn","c_root_id_B":"d6m5opa","created_at_utc_A":1471485360,"created_at_utc_B":1471491296,"score_A":128,"score_B":3819,"human_ref_A":"I believe it's not mathematically beatable anymore in the vast majority of places.

Depending on if many face cards were or weren't dealt for a period, the big bettor could come in and start playing with a significant edge. And you'd have to be very discreet, because you could easily get kicked out if you were suspected of doing this. edit: It's come to my attention that it probably still IS mathematically beatable for a small edge in most places. Don't play online BJ though. That shit's the devil. Carry on.","human_ref_B":"Blackjack is the only game who's outcome is dependent upon past actions. Like, once an ace is played and discarded players know that ace is gone and won't be seen again. Keeping track of what cards have been played can give a player good prediction of what will come up. Knowing that they can adjust their bets so they win big when odds are good and loose little when odds are bad. Casinos fight against this by using multiple decks of cards, re-shuffling at random times, and good old intimidation. \"Card counting\" (the simple process of keeping track of what's been played and understanding current odds) mathematically gives a player a 0.5% advantage over the house. Some say it's as high as 1%, some say 0.1%. But, no matter what, it won't make you rich over night. To see a 0.5% advantage pay off you'll have to play a lot and over a significant amount of time. Those who did get rich with card counting did it with a team. And, don't forget, casinos can ask anyone to leave for no reason at all. If you're statistically winning more than you should, you may get a tap on your shoulder. So, mathematically, yes, you'll have an advantage in blackjack because it is a continuing, past dependent, outcome. But, in real life, you simply won't be allowed to sit at a table and take the Casino's money.","labels":0,"seconds_difference":270.0,"score_ratio":6.2578125} +{"post_id":"4y9gz3","domain":"explainlikeimfive_test","upvote_ratio":0.84,"history":"Explain like I'm five years old: Why is Blackjack the only mathematically beatable game in casino?","c_root_id_A":"d6m1vmn","c_root_id_B":"d6m5jg3","created_at_utc_A":1471485360,"created_at_utc_B":1471491045,"score_A":128,"score_B":135,"human_ref_A":"I believe it's not mathematically beatable anymore in the vast majority of places.

Not a card counter but know plenty who do (or did). 1) Perfect basic strategy without counting + good house rules gets you very close to 50% equity. It's over 49%. This is reduced significantly by bad house rules (ie pay 6:5 on blackjack). You cannot get over 50% without counting and properly adjusting your bets based on the odds for that hand. 2) Part of why you can beat blackjack is the \"history\" as has been mentioned. The other part is the ability to bet SIGNIFICANTLY more when you have an edge vs when you don't. Betting $10 many times as 49.8% dog, and then $50 or $100 a few times as a 54% favorite, will yield positive equity and thus profit in the long run. 3) Blackjack is still very beatable, but casinos have gotten much smarter over the years. The rules are generally worse and favor the house more than in years past. They're better at spotting counters and teams. I know a number of people who have made significant money (well into 6 figures) by counting, and have subsequently been banned or flat bet. It's a good way to make short-term money if you know what you're doing, but you need a significant bankroll as the swings can be enormous. 4) Assuming you're not counting, then other players playing correctly or incorrectly will NOT affect your equity. Someone hitting when they should stay is just as likely to help you as hurt you, so leave them alone and let them do as they please. Anyone saying otherwise does not understand statistics. EDIT TO ADD 5) Some comments have mentioned poker, sports betting, horse racing, and certain video poker \/ slots as other profitable opportunities if you know what you're doing. Poker is obviously true, as many people make their living playing poker. The key difference is that you play against other players and simply pay the casino a flat rate, so they don't care if you win. Literally thousands and probably tens of thousands of people around the world make their living playing poker, both in casinos and online. Sports betting is true, although it takes a lot of work and very good computer models to beat it. Also never, ever, ever pay for a tout service to give you picks. 100% of them are scams. Horse racing I'm honestly not sure about, as I know next to nothing about it. But I've been in Vegas a long time and have never met someone who is a professional horse bettor. Anecdotally, everyone in that section of the sports book looks like a degenerate (or someone just having fun on vacation). But maybe? If anyone knows more I'd like to hear. Video poker \/ slots is also true under certain circumstances. Some of the progressive jackpot slots can actually be pretty lucrative when the jackpot gets big enough, but it's an enormous time sink and requires an enormous bankroll. I know people that have tried to take advantage, and they give up after not too long. The edge on profitable video poker machines is small and you're not going to make any significant money grinding those. Minimum wage maybe. People who are VERY good at heads up limit holdem can beat the poker machines (NOT video poker, but actual poker played against an AI). The AI is awfully good though, and will absolutely obliterate a random tourist. They put these things outside of poker rooms and they must absolutely print money on them to an absurd degree.","labels":0,"seconds_difference":5685.0,"score_ratio":1.0546875} +{"post_id":"bkau81","domain":"explainlikeimfive_test","upvote_ratio":0.94,"history":"Explain like I'm five years old: How do series like Planet Earth capture footage of things like the inside of ant hills, or sharks feeding off of a dead whale?

For example, I put my ceramic coffee mugs into the rack upside down, and the bottoms, which are slightly concave, are still wet when I pull them out. My ceramic plates I put it on edge and are dry. My tubberware, like my coffee mugs, aren't edge down, and the water catches in the nooks and crannies in the same way. The shape of an edge-down dish or flat surface allows the water to spread out, which gives it more surface area to evaporate or plain drip off. When there's a curve to catch water, like the lip under a tubberware edge, the water can \"pile up\" on top of itself, so it takes many times longer to evaporate. At least in my dishwasher, those are the areas where water accumulates for me, regardless of the dish's material. Edit: If we're going to talk heat capacities, water has the highest heat capacity of any of these materials by a considerable margin, so merely the surface-to-surface contact of water with a dish, whether plastic or glass or ceramic, isn't going to mean as much if the water is stacked up in a groove insulating itself. The surface area:volume should be the greatest factor, imo.

(This is especially important to know if you happen to be allergic to bee venom. Like I am.) When a honeybee stings you it leaves a small and still-pulsating venom sac that is attached to the back (non-pointy) end of the stinger.\u00a0 That sac is still mostly full, initially, and will continue to deliver venom into you through the stinger unless & until both can be removed. Without knowing any better, most of us would simply pull out the stinger & sac between our thumb & index finger. This is NOT a good approach\u00a0 because by doing so you are literally injecting the rest of the sac\u2019s venom into yourself. A much better way to remove a stinger from the skin is to scrape it upward from the side, as opposed to grabbing it from the top.\u00a0 Using a knife blade (or even a fingernail if you have one that is long enough) catch the stinger from BENEATH the sac and lift it all upward. This way you won\u2019t receive nearly as much of the sac\u2019s still available venom.\u00a0 Hope this is helpful.

In the case of chemical energy, you have to break weak, unstable bonds and form strong, more stable bonds. Since all chemistry boils down to how atoms are sharing their electrons, the most energy you can get is going to come from an atom grabbing onto an electron really hard to form that strong, stable bond. Few elements will grab electrons harder than oxygen. That's what oxygen is doing in our bodies: it's the end of a long chain of passing an energized electron between different molecules, incrementally taking some of the energy out of it until the oxygen takes it. It's like pouring water through a generator. You can either start with water really high up, or drop it really far down. Oxygen is *almost* the most \"down\" the electron can get. Almost, because fluorine would be lower, but fluorine is more dangerous and harder to get. It's dangerous because it can grab electrons from other molecules that aren't supposed to be giving them up, ruining that molecule and damaging the cell. In fact, oxygen does this, too, and your body has a lot of mechanisms to control it as much as possible and repair the inevitable damage. Fluorine grabs electrons *so* hard that it's virtually impossible for your cells to control it. Fluorine also holds onto the electrons it's already grabbed super hard. Fluorine forms *very* stable bonds, which means it's not usually free to form new ones. If you're pouring water through a generator and the hole it ends up in is already full, the water can't flow through the generator. To empty the hole, you have to add energy back in - by definition, more than you get back out. Bonds with oxygen are also very strong, but they're *just* weak enough that clever bacteria evolved a way to use sunlight to break those bonds and form free oxygen. The energy is free, provided by the Sun, and very plentiful. But sunlight isn't powerful enough to break fluorine bonds, so there's no fluorine available to use to take electrons in your cells. All of this makes oxygen the ideal source of energy for all living things. The physics that make that true on Earth are true everywhere else. It's absolutely possible for life to use something else - life on Earth did so for millions of years before cyanobacteria evolved photosynthesis and aerobic respiration, and still thrives in oxygen- poor places on Earth. However, life without oxygen doesn't have nearly as much energy to work with. Complex, multicellular life is *possible* without oxygen on Earth, but it's very very rare. With a few exceptions anaerobic life is limited to single cells like bacteria and archea, and slime molds. Also, because oxygen is so reactive it doesn't tend to stick around long as O2 before bonding to something else, like carbon to make CO2. If O2 molecules are abundant in an atmosphere, something has to be constantly making it, probably by ripping it off other molecules. That takes adding energy in. There are chemical processes that do that without life, but it *could* be an early, obvious sign that's worth looking into. Of course, there could be another way for complex life to form.

So much. Here's a quick overview. Simplified, you sleep in a couple different phases: REM (Rapid Eye Movement, the dreaming phase), and NREM, often split into NREM 1 and 2\/ NREM 3 and 4 (slow wave, \"deep\" sleep). Each of these types of sleep has a different job. During REM sleep, all the stuff you experienced and learned during the day gets replayed over and over, along with other old memories that your brain tries to mash together, making new connections and strengthening memories. A lot of inspiration comes from dreaming, because you just can't try out as many combinations of thoughts and ideas when you are awake. It's extremely important for memory and brain development, like another person said. Dreaming is also very important for getting over traumatic events, as dreams will make you relive them, but a very important stress hormone in your brain is turned off, so you can process the grief and other feelings without the trauma. PTSD, by the way, is what happens when this system fails. In NREM 1 and 2, one of the cool things that happens is that \"muscle memory\" is developed. Ever practiced something, got frustrated and stopped, and after sleeping on it, suddenly been able to do it? Your brain practices in your sleep. If you're trying to learn a new skill, make sure to get enough sleep. Deep NREM is the part where your brain reorganizes everything. Useless memories out, important memories saved and put into long-term storage. This part is extremely important for reducing anxiety and stress, as well as memory. Not only does this help you remember the things you learned from that day, it also clears up your short-term memory storage (basically like RAM) so you can start again in the morning. Don't underestimate the difference this makes. You can't put memories into long-term storage while awake, and you are losing them constantly as new ones replace them. Your blood pressure also goes way down, your heart gets some TLC, your whole body gets restored. Like another user said, toxins are flushed out. One important \"toxin\" is so-called amyloid plaque, a mess of proteins that you produce, and that get caught in your brain, every second you are awake. These destroy your brain and memory if allowed to keep growing unchecked. The *only* way to get rid of them is to get enough high-quality sleep, every night. These proteins are the reason older people get diseases like Alzheimer's: older people are often not able to sleep for as long as younger people. That is why it is so important to protect yourself from amyloid plaque by always getting 8 hours of sleep. I will stop now, but there is so much more happening during sleep, and so many studies proving it. Please ask if there is anything else you want to know! **TL;DR:** Body and brain are restored, memories processed, consolidated, and sent to long-term memory, stress, anxiety, and trauma reduced, blood pressure reduced, muscle memory developed, brain growth\/new ideas. Yes, 7-8 hours of sleep are necessary, even for the people who feel okay after less.","human_ref_B":"Quite new data shows that there are small drainages or \"sewer system\" in brain that activates when you sleep.

It has to do with how humans use energy - most creatures create energy as it\u2019s needed, for the tasks needed at any given time. More complex systems have more energy demand, but have the benefit of adaptability - a simple creature that only eats algae will only have organs needed to intake and convert algae to energy, and likely will convert it as it\u2019s needed, but will as a result have limited energy for things such as moving quickly away from predators. There does seem to be a link to energy demand and sleep - creatures that perform high intensity activities during their time awake tend to sleep more while slow moving creatures tend to sleep rarely and some never sleep. The reason we do things such as close our eyes and relax is it allows the body to mostly guarantee that energy that COULD be spent on running, analyzing the environment, so on that COULD be needed immediately won\u2019t happen, so it can safely move energy to body systems for maintenance. Think about a time you had a bad injury - even if it was just a really bad hit to the shin, you are going to feel less energetic. You usually won\u2019t fall asleep though - the body can repair itself while you\u2019re awake but it does it slower.

So much. Here's a quick overview. Simplified, you sleep in a couple different phases: REM (Rapid Eye Movement, the dreaming phase), and NREM, often split into NREM 1 and 2\/ NREM 3 and 4 (slow wave, \"deep\" sleep). Each of these types of sleep has a different job. During REM sleep, all the stuff you experienced and learned during the day gets replayed over and over, along with other old memories that your brain tries to mash together, making new connections and strengthening memories. A lot of inspiration comes from dreaming, because you just can't try out as many combinations of thoughts and ideas when you are awake. It's extremely important for memory and brain development, like another person said. Dreaming is also very important for getting over traumatic events, as dreams will make you relive them, but a very important stress hormone in your brain is turned off, so you can process the grief and other feelings without the trauma. PTSD, by the way, is what happens when this system fails. In NREM 1 and 2, one of the cool things that happens is that \"muscle memory\" is developed. Ever practiced something, got frustrated and stopped, and after sleeping on it, suddenly been able to do it? Your brain practices in your sleep. If you're trying to learn a new skill, make sure to get enough sleep. Deep NREM is the part where your brain reorganizes everything. Useless memories out, important memories saved and put into long-term storage. This part is extremely important for reducing anxiety and stress, as well as memory. Not only does this help you remember the things you learned from that day, it also clears up your short-term memory storage (basically like RAM) so you can start again in the morning. Don't underestimate the difference this makes. You can't put memories into long-term storage while awake, and you are losing them constantly as new ones replace them. Your blood pressure also goes way down, your heart gets some TLC, your whole body gets restored. Like another user said, toxins are flushed out. One important \"toxin\" is so-called amyloid plaque, a mess of proteins that you produce, and that get caught in your brain, every second you are awake. These destroy your brain and memory if allowed to keep growing unchecked. The *only* way to get rid of them is to get enough high-quality sleep, every night. These proteins are the reason older people get diseases like Alzheimer's: older people are often not able to sleep for as long as younger people. That is why it is so important to protect yourself from amyloid plaque by always getting 8 hours of sleep. I will stop now, but there is so much more happening during sleep, and so many studies proving it. Please ask if there is anything else you want to know! **TL;DR:** Body and brain are restored, memories processed, consolidated, and sent to long-term memory, stress, anxiety, and trauma reduced, blood pressure reduced, muscle memory developed, brain growth\/new ideas. Yes, 7-8 hours of sleep are necessary, even for the people who feel okay after less.","human_ref_B":"The best answer I\u2019ve seen is your body actually doesn\u2019t do much different while you sleep but does a lot of things faster such as cell growth.

They do overlap making it a question that can be unique to each individual. Lifestyle- As we age life becomes more demanding and stressful. We get jobs, go to school, start families and form more complex social lives and adopting energy consuming roles in society. On average, children and teenagers have a lot less to worry about in terms of stress than someone who has the above mentioned established. That's why it is important to rest when stressed and get sleep in. Yes, diet, exercise and hydration influence fatigue, lol. Biology- Genes can be triggered or damaged over a person's lifetime to affect so many aspects of their functioning. Things like hormones and genetic diseases can affect a person's fatigue as they grow older. Some hormones that influence sleep actually decrease as we age.

This allows them to put the chips into smaller packages without risk of overheating, possibly even stack multiple chips on top of each other into a single package like they do with memory cards. But the 4 GB modules aren't anywhere near their maximum capacity. You can buy 16, 32, 64 and in the near future even 128 GB modules, which all fit into the same form factor.","human_ref_B":"In addition to what others have said about existing standards: * The RAM stick standard size is based off RAM sticks from well over a decade ago. Desktop RAM sticks have larger contacts than laptop RAM for more stable contacts (see ref pic halfway down on this StackOverflow article). Part of the reason is the NUMBER of contacts. The DDR4 standard, for example, defines a certain number of pins, the data path 'width' per cycle. Fewer pin contacts would require a different standard but ALSO be much harder to reach the same speeds with. * There is the SO-DIMM standard. However, it's not MUCH smaller (about half the length) and requires far more compact traces, which are more failure-prone. It's used heavily in laptops with upgradable RAM, but even this is too big for a lot of devices. In laptops, that stick is laying down - which takes a LOT of valuable motherboard space - while also still adding a good .5\" thickness. Apple is a good example of this - their laptops haven't had upgradable RAM in years, and part of the reason is that they try to minimize thickness (to an unhealthy degree). * We don't use SO-DIMM in desktops because the motherboard space isn't as much of a premium, and because we tend to want to maximize speed instead. RAM can have a number of different compromises, but it can't be fast, cheap AND space efficient. Pick 2. :) * Many laptops (and even some Small-Form Factor desktops) often have RAM chips directly soldiered-on the motherboard to deal with this very issue. However, this has substantial downsides - more custom engineering, higher manufacturing cost, higher repair\/replacement costs. * Many phones use higher density modules (RAM chips) to help save space, and package-on-package is being used to save even more. For example, the Samsung Galaxy S9+ has 6GB, and in this teardown on iFixit, it's embedded on the CPU in a second layer. This makes sense - the CPU and GPU are in the single SOC, and they are really the only things that need direct RAM access, so all of those connections skip the 'motherboard' entirely and are just in the SOC package. Meanwhile, if you look at the part number for that RAM chip on Samsung's site, it's listed as 48Gb (RAM chips, unlike sticks, are listed in Gigabits, not Gigabytes). That's VERY high density. That high density is also VERY expensive. Compare that with this cheap stick of 4GB DDR4 desktop RAM; it's not worried about space savings (in fact, only half of one side of the PCB is used!), and is instead using 4x 8Gb chips to reach 4GB. Those low density chips are much less expensive, and PCB traces map them to the full DDR4 standard (with the help of a very tiny chip in the middle of the PCB). ​ So TL;DR: The industry never came up with a smaller RAM board standard than DIMM\/SO-DIMM because you need a large number of contacts for RAM to be fast. Very high density RAM is MUCH more expensive, and since space is not at a premium and there is the option to put it directly on the motherboard or in a package-on-package solution, there isn't enough demand to justify the work on one.

You can make a simple electromagnet at home to show that this works. The opposite also happens, when you move a magnetic field across a conductor it will induce current. This is how we generate most electricity: steam from burning coal, water from a dam, or wind is used to rotate magnets past coiled wires. So, now, what happens when you try and move a magnet across a piece of aluminum, which is conductive. As the magnet \u2013 and its magnetic field \u2013\u00a0move, it creates electricity (specifically called eddy currents) inside the aluminum. These currents, in turn, create a magnetic field, and this magnetic field opposes the motion of the magnet. This can be used then, to separate metal from non-metals. By rapidly moving magnets (or using a quickly changing electromagnet), conductive materials are induced to move, and a setup is made where metal objects will be thrown forward, and non-metals fall from gravity.

You first get a 'flash' which means that blood has entered the needle. You then advance a plastic tube, which is the catheter, inside the vein. Once you are in the vein you pull blood back into the syringe which confirms that you are not in dead space or tissue. You then 'flush' the catheter with normal saline. Sometimes the vein can blow and you will see pooling of saline or blood. You know you are not in. A fun side note: when you give medicines in the muscle you should pull back on the plunger expecting no blood to make sure that you aren't in an artery or vein for the exact opposite reason .

Thanks!","c_root_id_A":"cvp5gid","c_root_id_B":"cvp05hu","created_at_utc_A":1444068679,"created_at_utc_B":1444060480,"score_A":5644,"score_B":404,"human_ref_A":"Alright, let's kick this one off. The Trans-Pacific Partnership is a multi-layered deal whose particulars have just been agreed upon by the twelve participating countries. Its stated purpose is to reduce **tariffs** - taxes on bringing your goods into a country or sending them out - and therefore encourage industry by making it cheaper for importers and exporters to conduct business between these countries. Its other stated goal is to create a set of easy **rules** that businesses can live by when dealing between these countries. The TPP is far more complex than that, however. Its subtextual function is to serve as a foundation from which to spread that set of easy rules to other Asian nations, with an eye to preventing China from setting standards among these countries first. The Obama administration is concerned that it's either \"us or them\" and that a Chinese-led trade agreement would set rules that American businesses would find problematic. So what does it mean for you? Let's assume you are a citizen of one of the participating nations. \u2022 A deal like the TPP involves identifying which tariffs affect **market access** and **competition** by creating a market that favors some producers over others instead of letting price, quality and consumer preference decide. For instance, it is very expensive to bring milk in to Canada, so even if you could sell your milk at a lower price, you will have to account for the cost of the tariffs, which will make your milk uncompetitive on the Canadian market. New Zealand and the US both want to see Canadian dairy tariffs lowered so that their milk producers can sell on the Canadian market more easily. \u2022 When the market can decide and the barriers are down, we expect to see **open markets** offering **more products\/services** than could previously have been made available. Prices should go down for certain products due to increased competition. \u2022 A deal with as many players as the TPP rarely functions on one-to-one trades; instead, each party has a list of things that they want and needs to go shopping around to find ways to get their positions filled - a chain of deals wherein, for instance, Japan pressures Canada on the milk issue so that they can in turn see motion on their own priority, such as car parts. This is why the negotiations have taken so long. \u2022 The TPP wants to **standardize** rules for trade among its participants, which cover a lot more than just tariffs and quotas. Other issues that have to be considered and negotiated include intellectual property rights and protections; rules regarding patents; environmental and labor regulations. In short, it tries to set standards on **how business is conducted**, both internationally and at home. It does this because uneven practices can result in uncompetitive market access. \u2022 This standardization is hoped to **improve labor and environmental laws** across the board, as the need to conform forces countries that have been lagging behind in their standards to catch up with the rest of the group. By setting rules that apply equally to the US as to Malaysia, it is hoped that **people will be better off** and enjoy more protections in their working environment. \u2022 To that end, the TPP will also have a process in place for what happens when someone breaks the rules - a **tribunal** which will decide based on terms laid out by the TPP instead of following the laws of any one government. This helps ensure that foreign companies are treated fairly and can conduct business under the same standards and with the same opportunities. **Tl;dr the TPP is out to make business between these 12 countries more fair, predictable and even. It should provide more choice in goods and services and more bang for your buck, while making labor standards improve for people outside of North America who may be operating under less protections than a Canadian or American enjoys.** --- What are some concerns? --- \u2022 The TPP has been negotiated in **heavy secrecy**. While it's easy to see why keeping such a huge deal secret from the public is problematic, it is also reasonable for governments to work on negotiations and come to terms before letting elected officials decide if the end result is in the public interest. It lets others at the bargaining table know that what is said there won't be changed by a public opinion poll two days later, and it has been argued that such secrecy is therefore necessary to make these meetings work at all. \u2022 The TPP has a **scope** that concerns many parties as it addresses trade and industry regulations on a 21st century scope - everything from upcoming cancer drugs to internet regulations to, yes, a cup of milk in Canada is all being covered by the same negotiation. It is a reasonable concern to say that the number of issues being covered in the same deal will make it hard for the public to reasonably read, understand and decide on. \u2022 The removal of tariffs provides new foreign opportunities for business, but it also means that industries which rely on a **protected domestic market** will become exposed. It is not unreasonable to suggest that any given country is trading away the success of industry A for success in industry B, which, if all things are equal, should come down to a zero-sum game. Economics does not, of course, work like that, but it's still a fair question to examine. \u2022 While supporters of the TPP say that it will encourage countries to improve their standards and reform, those elements are at their strongest during the negotiation - and the heat on issues such as human trafficking and human rights abuses have been sidelined as pressure to secure a deal of any kind has mounted on major nations facing upcoming elections. What should have been an opportunity to engage and demand reform as a condition of involvement in such a major global trade deal has been left by the wayside, a casualty of ambition. --- What are the serious issues? --- \u2022 While the TPP has been kept secret from the public, **large corporate interests** have had a seat at the table throughout the process. These businesses have an **obligation** to make as much money as possible for their shareholders. This means that a great many of the deals that form the basis of the TPP have been negotiated with an eye to advantaging those businesses, potentially at the expense of the average citizen. \u2022 \"Free trade\" as the TPP proposes is **nothing new** - globalization has already happened, and we are all the beneficiaries. What this deal will offer is not for the average citizen, who might see a few price differences on common products - it is for the large corporate interests who will have more freedom to **move jobs** and production to areas where it is cheaper to conduct business. \u2022 There should be no such areas within the TPP zone, but part of the negotiation involves **exceptions** in place specifically to help these companies. The consistent standards that the TPP desires to set? Corporations would like to see those **standards lowered** - it is in their best interest to have access to a labor, property and capital market where they pay the least amount of money to conduct their business. \u2022 Tariffs exist in part to protect domestic industry - **jobs** - from the vagaries of a global market. If cheaper US milk is sold in Canada, Canadian milk producers will have to choose whether to sell their own products more cheaply or else close down and go out of business. If it is not possible for these farmers to sell at a lower price and still remain profitable, then that choice is not a choice at all. \u2022 The TPP's intellectual property provisions, which have been the subject of several leaks, are **harsher than existing law**, a product (again) of corporate involvement in the deal. They aim to crack down on several ways people use intellectual property, fairly and otherwise, and their scope means there is significant possibility for abuse and harrassment. \u2022 More damagingly, the TPP **applies those laws to drugs** with an eye to preventing cheaper medicine from being available on the market - products that by rights **should** be subject to competition as their prices are heavily inflated beyond the cost of production. \u2022 The TPP will offer a method by which companies can **attack laws that affect them**, suing governments through a tribunal for such offenses as trying to protect youth from cigarette marketing images, trying to protect the environment from dangerous industrial contaminants, or even refusing to pass laws removing or suppressing regulations where beneficial to corporate activity. These are all issues that already happen under various trade deals. \u2022 We, the public, and our elected representatives will not have a great deal of time or means to push back against this trade deal if we dislike it. The text will only be released when absolutely necessary (a period of 60 days in the US) and steps have already been taken to ensure that elected officials cannot muck about with the deal. While this is logical (it would not be fair to negotiate terms and then change them back at home without discussing it), it does mean that instead of being able to debate and dissect we're committed to an **all-or-nothing deal**. **Tl;dr the TPP puts local industries at risk, threatens jobs, attacks your privacy, and you may be looking at paying more for important medications (either directly or through your government). It's being sold as lower prices and better standards across the board, but lower prices are meaningless by themselves - purchasing power is what you really want - and there is no guarantee that standards need to be raised instead of lowered.** Anyone with questions, comments, concerns, let me know here or via PM and I'll be happy to help.","human_ref_B":"Can someone please just eli5?

The nerve cells may die; or they may not die but they certainly don't reconnect with where they should connect. That stops signals getting through which is why you get problems of paralysis or loss of sensation, depending on where the damage is. That's why a stroke is so disabling. > In the skin the nerve cells there seem to be able to survive injury. They also seem to be able to re-grow to their targets so they go back to where they connected to in the first place. So if it was a muscle they were supposed to be supplying, they'll reconnect with the muscle. If it was a patch of skin they can branch out and re-supply the skin so you do get sensation back.","labels":0,"seconds_difference":10833.0,"score_ratio":1.0816326531} +{"post_id":"yvx48k","domain":"explainlikeimfive_test","upvote_ratio":0.93,"history":"Explain like I'm five years old: Can a person feel pain or other sensations in a transplanted organ?

I am able to feel sharp pains and can tell when something is wrong, but cannot feel anything else.

Usually when we feel pain like a stomach ache, or chest pain, or appendicitis, the pain we are feeling is localized inflammation affecting the surrounding tissue that does have sensory nerves. Now of note, is that nerves can actually heal. They may not heal completely or correctly, but they can heal. Nerves can regrow at a rate of up to 1 inch per month. These are peripheral nerves that exist outside our brain and spine. Central nerves can also regrow, but often times the injury that caused them to be severed releases a hormone that prevents regrowth from happening. This is why central nerve conditions are often permanent. Medicine is working on ways to prevent the release of that hormone, but so far the trouble we are running into is time. The process starts quick, and most patients with traumatic injuries don't make it in time to have a chance at preventing it. As for your question about transplanted organs specifically, of the organs that we know we can transplant, most are able to receive nerve growth and and even restore sensory development. Retinal transplants can restore sight. Gastric organs like the intestines and stomach that require autonomic muscle contractions to push food stuff through can restore that function. The process is pretty simple. Just like any other tissue, the nerves respond to hormones and signals and grow till those hormones and signals are copacetic and achieving the function they think they need to. (that's the key part, the nerves are not guaranteed to regrow or reattach correctly and this can cause issue but often we can treat those issues and its far better than dealing with a failed organ.)","labels":1,"seconds_difference":3556.0,"score_ratio":1.125} +{"post_id":"ycmk8m","domain":"explainlikeimfive_test","upvote_ratio":0.9,"history":"Explain like I'm five years old why boiled egg shells can sometimes be easy to peel and other times stick and take chunks of egg with them","c_root_id_A":"itn37ii","c_root_id_B":"itn9ine","created_at_utc_A":1666646308,"created_at_utc_B":1666648907,"score_A":27,"score_B":96,"human_ref_A":"The shell of a fresh egg is full, but the shell is porous, so as it ages some liquid evaporates through the shell.

Initially both groups had similar distance to their new spawning ground - the Sargasso sea, but as continental drift continued westward, the American eel can chill, while the European eels today have to travel 5000-6000 km to their spawning grounds.

In a sense, a built-in instinct to be extremely gullible is an evolutionary advantage for a child. Being gullible means you learn faster because you don't try to filter any of what you're being taught through skeptical analysis. But it comes with the downside that you learn *everything* you're being told, both true and false. How big a downside that is varies depending on the ratio of true information to false information that you are being taught. For a naive child who knows very little about the world, being taught by the child's parents and grandparents, there's so much new good knowledge to soak in that it's worth it to speed the process up even if that means it comes with the occasional bad knowledge. The kid is drinking from a firehose of information and has to take in as much as possible as fast as possible. But as the kid grows up and becomes an adult, a distrust of new information grows. This is because as they catch up to the knowledge of the tribal elders and become just as schooled as everyone else, the ratio of good new information to bad new information changes. Now if the information is truly new, and *especially* if it requires having to un-learn previous information because the new information contradicts the old, the probability that this is because the new information is wrong is much higher than it was when you were a child. Now the same gullibility that served you well as a child is a detriment as an adult. So it's not surprising that adults are more \"set in their ways\". It's how our instincts have taught us to be. Because it was actually a good idea once upon a time. But in modern times, the rate of new information being learned each decade is much higher than it was for our ancestors. When technology and society moved slowly, information you learned as a child was still good information 50 years later. With the rate of change these days this is less true than it once was. But instincts drilled into our DNA don't change as fast as our society does. We may work in office buildings typing onto computers, but our brains are still optimized for the life of a hunter-gatherer wandering the grasslands. Finding the right point between the disadvantage of gullibility (believing everything new) and the disadvantage of rigidity (believing nothing new), is a delicate balance. You can apply the open-minded but still skeptical reasoning of empirical analysis, but this is actually NOT something we're as good at as we like to think we are. It takes *work* to suppress your instincts and think in that \"scientific\" sort of way instead.","labels":0,"seconds_difference":18557.0,"score_ratio":1.4} +{"post_id":"ogfrbp","domain":"explainlikeimfive_test","upvote_ratio":0.68,"history":"Explain like I'm five years old: How did Queen Victoria manage to get her descendents onto the throne of so many European Monarchies?

Monarchs for ages have had arranged marriages for their children so that they can create political alliances. When the Duke next door happens to also be your Son in Law it's a lot more likely you'll be able to count on him for support. Queen Victoria had 9 children (not unusual for the time) and arranged for them to be married into the royal families of Europe in order to create such alliances. This wasn't unique to her, medieval monarchs had been doing that sort of thing since antiquity. Queen Victoria's case wasn't unique but it was unusual because of just how many powerful royal families in Europe she was able to marry her kids into. The British Empire was at its height at the time and other royal families were keen to make alliances with Britain. This kind of backfired though, WW1 in a sense was the war of the cousins. The monarchs of the most powerful nations at the time Czar Nicholas II, Kaiser Wilhelm, and King George V were all cousins. In fact if you look at their pictures side by side there is a remarkable similarity in appearance between them. The problem became that Nicholas and Wilhelm in particular were incompetent rulers and functionally ended the monarchies in their nations when they were deposed. The great irony of Queen Victoria is that she tried to unite Europe under single family but actually ended up ending the monarchy across Europe within a single generation due to the incompetence of her own Grandchildren. Within a decade the turmoil caused by the war would see those same nations end up under the Communists and Nazi's.","human_ref_B":"Victoria and Albert had 9 children.

There are at least three variants of water-consuming datacenter cooling. 1. The datacenter captures the hot air coming out of servers. Radiators with cool water circulating through them are used to cool this hot air. The water is heated while the air is cooled. That water is then pumped outside and poured over big fiber boards while a fan blows outside air past them. This evaporates some of the water, and the remainder is cooled by the evaporation. The remaining cooled water is pumped back inside the datacenter and the process repeats. 2. The datacenter uses industrial air conditioning units called CRACs, which have radiators outside the datacenter. The air conditioner compresses a gas, heating it up, and then pumps it through the radiator while a fan blows outside air across the radiators. Once the compressed gas is cooled, it is brought back into the datacenter and allowed to expand, which makes it cold. Air inside the datacenter is blown over a different radiator filled with this cold gas, cooling the datacenter air. On very hot days, the CRAC sprays the outside radiators with water, which evaporates on the radiator and cools it more than the air alone would. 3. The datacenter brings in outside air directly to keep the inside air cool. On hot days, the datacenter's systems will spray a mist of water into the air on its way in.

It takes a lot of energy for water to go from (hot) liquid to gas, which means that a small amount of water being evaporated gets you a lot of cooling capacity. However, the reverse is also true; when water goes from gas to liquid, it dumps that heat into everything around it. So if you're using evaporative cooling, then you necessarily have to eject the gaseous water as well, otherwise you're just cycling the heat from one part of the facility to another. But since you're ejecting water from the system, you need to bring in more water to replace it. Hence, you're a net \"consumer\" of water, as that water can't be used anymore. The alternative is to use a nearby river or waterway as a heat sink. You bring cool water in from the river, run it through the cooling system to bring it from cool to warm or hot, and then dump that water back into the river, further downstream. Again, you're \"consuming\" water, except now you're also heating up the local waterway, which could have unforeseen consequences on the local wildlife.","labels":1,"seconds_difference":30210.0,"score_ratio":1.4155844156} +{"post_id":"yzlsoj","domain":"explainlikeimfive_test","upvote_ratio":0.94,"history":"Explain like I'm five years old: Why do datacenters continuously use more water instead of recycling the same water in a closed loop system?","c_root_id_A":"ix2e6u1","c_root_id_B":"ix11jjw","created_at_utc_A":1668921904,"created_at_utc_B":1668897312,"score_A":109,"score_B":22,"human_ref_A":"AH! a question in an area of my expertise.

So the command centre \"expands\" (duplicates) and gives a copy of the blueprint to the duplicate and tells it 'go and build a leg' or brain etc. Essentially it is told to only work on a specific section of the blueprint. The rest is crossed out and none of its concern. The command centre working on the leg eventually splits into command centres working on the veins, the muscles, the skin, etc, much like how in a building multiple different companies will install water and electricity, and the entire building itself of course.

In the standard power grid, there is no storage except on the kinetic energy of the spinning turbines. The system is self-balancing on timescales of seconds, and power plants regulate their output to match demand over minutes to days. Of course there are exceptions these days. When your solar panel pumps power onto the grid, it speeds up all those generators, so their owners have to burn less fuel to keep them running.

Primarily, the grid is supposed to run off a fixed frequency (50Hz or 60Hz depending on country). At the grid level, an over consumption of power will naturally cause the frequency to drop and an over supply will cause the frequency to increase. The power generators and grid companies monitor this to adjust demand to supply. As of today, there isn't many good ways to store a great deal of excess power generated. There are pumped hydro plants (fairly rare) and some areas are deploying battery storage (even rarer, very expensive) These have very limited capacity (probably just a few hours of demand at best). In general the utilities have to adjust supply to demand based on monitoring the system. There is a very huge and complex system that operates in unusual circumstances - such as an unexpected decrease in supply (a major generator goes down). Each grid usually have some peaking plants - usually gas fired power plants that can be turned on and off fairly quickly in response to demand. Grids can (usually) borrow power from each other for relatively minor problems over short periods and in major incidents, grid operators will organize rolling blackouts or brownouts to reduce demand.","labels":1,"seconds_difference":547.0,"score_ratio":5.5} +{"post_id":"q9jxf9","domain":"explainlikeimfive_test","upvote_ratio":0.67,"history":"Explain like I'm five years old: Why exactly are back pains so common as people age?

Roughly similar lineage of people stayed living there and the Latin name wasn't forced to change, so the Latin name stuck in English (and Italian). However, not all Latin influenced languages used the same name. The French call Deutschland \"Allemagne\" from the name Alemmani which were a group of tribes in the area. Then, you have exonyms that a country or people wants to change. For example, modern Iran used to be called \"Persia\" in English from Greek Pers\u00eds from Old Persian name for Cyrus the Great's people. Officially the name was changed to Iran by request of one of Iran's old leaders. Iran is roughly a changed spelling of the old Iranian word \u0113r\u0101n which describes a people who lived in the area. However, during WW2, the Allies changed the name on maps back to Persia to avoid confusing it with Iraq, then it changed back to Iran, then some Iranians wanted to bring back the name Persia to connect Iran back to the old glory of the \"Persian Empire\" (and distance from the current Iranian government). Now the name Iran and Persia are both acceptable. So, for political and historic reasons, the exonym for Iran changed multiple times, often because people wanted actively to change the name for various reasons. So... Exonyms are complex. They are often transmitted across languages and history and thus morph with time like all language. But country names are also political so sometimes exonyms are officially changed by governments or people. Istanbul was Constantinople Now it's Istanbul, not Constantinople Been a long time gone, Constantinople Now it's Turkish delight on a moonlit night. Even old New York was once New Amsterdam.

What you see is just the stuff that is currently working. And to provide info that no one asked for: evolution and natural selection work on geological time scale, and the driving force are just random mutations that naturally happen. Tiny and random changes that happen across thousands or millions of generations of living creatures, and those with a favorable change survive to make babies that carry those genetic mutations, and those babies make more babies with more mutations over thousands of years. The accumulation of these tiny generational genetic mutations eventually give rise to all the vastly different types of plants and animals you see today. And the common factor to all of these different species is that they're \"good enough\" for their environment. You see, natural selection doesn't mean nature \"picks\" the best traits and make more individuals carrying those traits, but rather the species randomly manifest a bunch of traits and nature just kills off all the ones that aren't \"good enough\". Sometimes many different traits of a same species are all good enough, so they all live on and branch out - divergent (think of the Darwin's finches), or certain traits are so good, that many different species that start manifesting that trait are all good enough and you see the opposite - a convergent (think of the species that all evolved into crabs). To come back to the question, a leaf bug doesn't just wake up and decide to look like a leaf, it's the result of a long lineage of bugs that very slowly became more leaf-like over millions of generations, starting from a bug that mutated and became some % more leaf-like than it's siblings, let's say 1%, then it survived and made 100 buglets, and 1 of those mutated again to be 2% more leaf-like than the original bug, which made it 2% more likely to survive predation, and to make more leafy bug babies. Repeat this process for not just the appearance, but the anatomy and behavior, over millions of years, and you get a leafy ass bug that looks like a leaf, behave like a leaf, all the while having no say in the matter, unaware of it's own leafiness, and if it's good enough to survive to sexual maturity, it too will make leafy bug babies with teeny tiny mutations and the cycle continues","labels":1,"seconds_difference":11428.0,"score_ratio":1.5} +{"post_id":"zwt43d","domain":"explainlikeimfive_test","upvote_ratio":0.92,"history":"Explain like I'm five years old: how are programming languages... programmed?

Writing programs in assembly is great and all, but how do we teach a computer a new language? Well, there are a few different options actually. 1. Write a compiler. A compiler is a program which takes in a file written in some programming language and spits out a file written in a different programming language (usually machine code). C is an example of a compiled language; every program written in C is always run through a compiler first and converted to machine code before it can be run. Some benefits of this are that programs written in C are really fast, since they\u2019re actually running in the computers native language, and as a user I don\u2019t have to install any extra stuff to get it to work. The downside is, though, that different computers have different n Native languages. A Mac does not understand the same machine code that a PC does, for example, so if I want to run the same app on my PC and my Mac, I need to write two different compilers and use them to create two different versions of my app! 2. Write a virtual machine. A virtual machine is a program which simulates an entire new computer inside your computer. This may seem pointless but since this \u201cenvironment\u201d is simulated, it can be designed to have whatever properties and understand whatever kind of code we want. Java is a language which runs on a virtual machine. When you run a java program, what actually happens is it first searches your computer for a version of the java virtual machine (JVM) and runs it, and then asks the virtual machine to run the program you clicked on. The benefit of this is that as long as there exists a virtual machine for your system, you can run the same java file on any system you want, no need for specific versions for MacOS or Windows, etc. The downsides are that you can\u2019t run java files at all unless you download the virtual machine first, which is not as user friendly, and also, as you might imagine, it is quite slow to simulate an entire virtual machine inside your system. 3. Write an interpreter. An interpreter is somewhat of a compromise between the previous two options. This is a program which takes a file written in one language and interprets it into instructions that the computer can execute. Whereas a compiler merely translates the code into another file, an interpreter actually runs the code. Python is an example of an interpreted language. When you run a Python program, you actually run the interpreter instead and give it the name of your program as a parameter, and it runs your program for you. Interpreters tend to be simpler and smaller than virtual machines, which can mean the languages that use them are faster in some cases - not Python, sadly, but some languages like Lua have interpreters that are so small, they can be packaged together with your app, so that users only have to download one file. Ok, that was probably too much information already, but there\u2019s still a big question: how do we write compilers, virtual machines, and interpreters? It\u2019s like a bottomless pit of logic; how do we teach a computer to understand something that\u2019s more complicated than what it already knows? Well, to truly answer that, I\u2019d recommend taking a college course on formal language theory. For now, suffice it to say that all programming languages are equally as capable as machine code - there\u2019s no program you could write in Python, or C, or Java that you couldn\u2019t write in plain machine code, and so, in a sense, no language is any more complicated than any other language. It\u2019s just a matter of translating from one to another, and to do that there is a useful conceptual tool called a grammar. A grammar is a way of boiling down the structure of a language to a few simple rules, like: A sentence is made up of a noun phrase, a verb, another noun phrase, and then an ending punctuation. A noun phrase can contain an article and a noun, a plural noun, or a proper noun. An ending punctuation can be a period, a question mark, or an exclamation mark. Using grammars, programmers can break down the huge task of interpreting a programming language into smaller tasks, and write their program in a way that it always has a sense of the possible pieces that could come next while it is reading the code.","labels":0,"seconds_difference":16207.0,"score_ratio":3.4375} +{"post_id":"zwt43d","domain":"explainlikeimfive_test","upvote_ratio":0.92,"history":"Explain like I'm five years old: how are programming languages... programmed?

So the French person talks to the translator in English (translation #1, by the original speaker in their head). Then the translator says it in Chinese (translation #2, by the intermediary). When we program, the programmer is taking their native language (in my case, English) and putting it into an intermediary language (like C++) that the translator knows. The translator in this case is a piece of software that knows both C++ and machine binary (the final language). So the first translation is done by the programmer into the intermediate language. Then the software translates it into the final (machine) language.","human_ref_B":"Others have already done a great job of explaining machine code, the series of ones and zeroes that computers actually operate with. Writing programs in assembly is great and all, but how do we teach a computer a new language? Well, there are a few different options actually. 1. Write a compiler. A compiler is a program which takes in a file written in some programming language and spits out a file written in a different programming language (usually machine code). C is an example of a compiled language; every program written in C is always run through a compiler first and converted to machine code before it can be run. Some benefits of this are that programs written in C are really fast, since they\u2019re actually running in the computers native language, and as a user I don\u2019t have to install any extra stuff to get it to work. The downside is, though, that different computers have different n Native languages. A Mac does not understand the same machine code that a PC does, for example, so if I want to run the same app on my PC and my Mac, I need to write two different compilers and use them to create two different versions of my app! 2. Write a virtual machine. A virtual machine is a program which simulates an entire new computer inside your computer. This may seem pointless but since this \u201cenvironment\u201d is simulated, it can be designed to have whatever properties and understand whatever kind of code we want. Java is a language which runs on a virtual machine. When you run a java program, what actually happens is it first searches your computer for a version of the java virtual machine (JVM) and runs it, and then asks the virtual machine to run the program you clicked on. The benefit of this is that as long as there exists a virtual machine for your system, you can run the same java file on any system you want, no need for specific versions for MacOS or Windows, etc. The downsides are that you can\u2019t run java files at all unless you download the virtual machine first, which is not as user friendly, and also, as you might imagine, it is quite slow to simulate an entire virtual machine inside your system. 3. Write an interpreter. An interpreter is somewhat of a compromise between the previous two options. This is a program which takes a file written in one language and interprets it into instructions that the computer can execute. Whereas a compiler merely translates the code into another file, an interpreter actually runs the code. Python is an example of an interpreted language. When you run a Python program, you actually run the interpreter instead and give it the name of your program as a parameter, and it runs your program for you. Interpreters tend to be simpler and smaller than virtual machines, which can mean the languages that use them are faster in some cases - not Python, sadly, but some languages like Lua have interpreters that are so small, they can be packaged together with your app, so that users only have to download one file. Ok, that was probably too much information already, but there\u2019s still a big question: how do we write compilers, virtual machines, and interpreters? It\u2019s like a bottomless pit of logic; how do we teach a computer to understand something that\u2019s more complicated than what it already knows? Well, to truly answer that, I\u2019d recommend taking a college course on formal language theory. For now, suffice it to say that all programming languages are equally as capable as machine code - there\u2019s no program you could write in Python, or C, or Java that you couldn\u2019t write in plain machine code, and so, in a sense, no language is any more complicated than any other language. It\u2019s just a matter of translating from one to another, and to do that there is a useful conceptual tool called a grammar. A grammar is a way of boiling down the structure of a language to a few simple rules, like: A sentence is made up of a noun phrase, a verb, another noun phrase, and then an ending punctuation. A noun phrase can contain an article and a noun, a plural noun, or a proper noun. An ending punctuation can be a period, a question mark, or an exclamation mark. Using grammars, programmers can break down the huge task of interpreting a programming language into smaller tasks, and write their program in a way that it always has a sense of the possible pieces that could come next while it is reading the code.","labels":0,"seconds_difference":15624.0,"score_ratio":3.6666666667} +{"post_id":"zwt43d","domain":"explainlikeimfive_test","upvote_ratio":0.92,"history":"Explain like I'm five years old: how are programming languages... programmed?

Each switch can be off or on (represented by 0 or 1). The combinations of 0s and 1s is what makes the computer do what it does. To control the switches, we use machine language. Machine language is a bare bones way of directly accessing each switch. It's super interesting, and super complicated, but working with processors in machine language helps you understand what goes on inside any computer\/processor. Machine language is super easy for the processor to understand, but it's harder for people to use. You might need 20, or even 100, lines in machine language to execute 1 line of python. So, we can invent programming languages that are easier for humans to use. Like python, C, etc. This applies to all programming languages, but I'll use python in my example. Python commands are essentially shortcuts to call the machine code that is needed to execute the line. So if you write a 1-line print statement in python, python translates it to execute those 20 or so lines of machine code. In the programming language or compiler, you (the programming language inventor) would associate the commands in your new language with the ones that need to be run in machine language.

The merchant deposited it in there bank. The merchants bank would send the check to the Fed. The Fed would record the transaction and debit\/credit the correct accounts.

Just a little tidbit on details of how amounts were recorded ... back when the amounts from each item (sales slips or whatever financial items) were written by hand on official entry sheets, that were totaled, and the totals handwritten into the ledger (as in, \"today's sales from store #3\") ... For each entry sheet that had the item amounts listed down a column, with description by each number, with a total at the bottom (document attached for each item, a sales slip or whatever) ... *... Before automated calculators* (before even the old calculating machines that were loud and clunky), **bookkeepers added the columns of numbers in their heads (with pencil notations if necessary), three times.** -- **Until they got the same total three consecutive times,** they kept going. Bookkeepers who could do three matching totals in one go were of course valued. -- **Then the entry sheet & attached docs were handed over to the next bookkeeper, who did the same thing on the same sheet column of numbers,** until they got **a matching total three consecutive times. ** -- That's how they arrived at totals. And eventually balanced the books. **Bookkeepers verified each other, and getting the same total three consecutive times was the key.** If two bookkeepers were getting a different total on the same entry sheet, they had to figure out exactly where the error was and why the error was occurring. One number looked like a '4' instead of a '9', or an attached record had a blurry number, that kind of thing. They had to show the manager how the difference was resolved. Nothing went forward until multiple people in the process agreed on the correctness of each total. *... Once bookkeepers were using automated calculators aka \"adding machines\"* that printed a slip of paper with all of the entered numbers and the total, **every totaled column of numbers had to have 3 calculator slips attached, with matching totals.** That was the total to enter in the ledger. **Both before & after adding machines, it was all about correct addition and subtraction, performed by humans. And the rigorous processes that supported those correct totals.** The really old machines that were *large* and *loud* sometimes ONLY added and subtracted. No other calculation functions. It was expensive to get one that would also multiply and divide. Those were reserved for higher-order financial job functions. Below is an image of old adding machine ... even in the 1980's these were EVERYWHERE in financial offices. IMO they sounded like a helicopter taking off. Twenty of these going high-speed all at once was the sound of the workspace. https:\/\/www.bonanza.com\/listings\/Vintage-Burroughs-Adding-Machine-Calculator-J-Series-Classic-FOR-PARTS\/1084924318?goog_pla=1&gpid=294505072980&keyword=&goog_pla=1&pos=&ad_type=pla&gclid=CjwKCAjwur-SBhB6EiwA5sKtji4frPQ4GMtNsXYhnrq6Yz3BtWdhFvmNZfO0jui4oLfrdmb6_NYX7RoCQ8gQAvD_BwE Those machines were literally hammered at high speed by bookkeepers for hours almost every day. Adding machines could become persnickety as they aged. They had to have frequent maintenance and be handled considerately, or they would become slow and sticky. Every office needed a machine guru to keep the machines happy and working. Image below - The so-much upgraded adding machines that became more available during the 80's ... still hammered for hours per day and needing constant love & attention to keep functioning well. Look - multiple math functions !!! Woohoo !!!

Any time a load is added or subtracted, a corresponding amount of generation must occur. There is a little wiggle room, but not much. So if a large power cable is cut, the grid either has to find an alternative destination for the supply, or it needs to cut supply by that amount. If the question is where the physical electricity in the wire goes, the best answer is that there is no electricity in the wire to go anywhere. The confusion likely comes from our shorthand thinking about electricity in that we think of it like water in a pipe. It's not really. That's a useful analogy that's not confusing for people, but it falls apart when too many questions get asked... Because it's not really the way things work. Think of a wire more like a phone line that tells a device in a circuit to consume power.

You can't ask them to just improve their skills with education - already an education is less and less likely to guarantee a job requiring that education - a big chunk of those newly unemployed factory workers and taxi drivers already have a college education. As well, an education is a really expensive thing for someone newly unemployed with a mortgage and a family to support. Many will become unemployed, and stay that way for a long long time.

He learned that at midday, during the summer solstice in Syene, a stick stuck in the ground didn't cast much of a shadow. So he asked himself \"Eratosthenes, do you think this might be the case here in Alexandria where I am?\" So he did the only sensible thing and stuck a stick in the ground at the same day and time. Lo and behold... there was a shadow. Well.. that's not supposed to happen... So let's look at that shadow... around 7 degrees or so. Interesting. The Greeks had already figured out that however far away the sun was, it was a long freaking way, and shouldn't have much effect on shadows of sticks. So if the shadow is 7 degrees, and I know how far it is from Syene to Alexandira, then I've got myself a sphere and I can work out how big it is with those numbers.

So if I want to store a lot of data, I need to have a lot of pages of graph paper, or else I need to make the squares really really small. The smaller the squares, the more expensive the printer, because the printer must be able to deposit very thin lines of ink onto the paper, which would require a very precise print head. The same goes for these SD cards. When we manufacture them, we are literally drawing an electric circuit onto a board. Part of that circuit is a grid that stores those 0's and 1's. So we need a very precise print head to draw that circuit. As the technology improved over the years, manufacturers are able to draw smaller grids in the same area. Not only are they able to draw smaller grids - they have also developed the technology to read from smaller grids. Remember that in the SD card, we are measuring whether each square has a positive or negative charge, not actually a zero or one. When we write data to the square, we are applying a positive or negative voltage to the atoms inside the square. When we read the data, we are checking whether each square has a positive or negative charge. The smaller the square, the fewer the atoms, and the lower the voltage.

This strategy, known as K-selection, is used by all large animals, including humans. The K-selected strategy works best if, once the animal reaches sexual maturity, it has a long life. That way, it can have lots of babies, even if each of one takes a long time to raise. That's why large species tend to live longer than smaller ones - because evolution selected those species for longevity.

I can't listen to the link now because my girlfriend is asleep and I don't feel like digging out my headphones, so if this doesn't really apply, I apologize. But. Harmonies are made of melodies. A C major chord has three notes, C, E and G (which any 5-year-old who gets piano lessons, including myself at age 5, will know, so no crap about that). Each of those notes has a little bit of melody inside, and it's those little bits of melody that make the harmony sound good! For example, sing along with me: C D E F G A B... Or, in solfege: Do re mi fa sol la ti... You REALLY want to sing the C or the do, right? That's because, when all of those notes come in order, the note B REALLY wants to go up to C, to resolve. The note F, on the other hand, really wants to resolve *down* to E. So if I play an F and a B together, the F will want to resolve to E and the B will want to resolve to C. Harmony! Why does a C major chord sound good, though? Other people have already explained that -- a pitch is when air shakes at a certain speed, and for every three times G shakes, C shakes twice. So if you play the C and the G together, their shakes will line up, and the brain likes that and thinks that it's nice. That's called a fifth. C to C, do to do, is called an octave. If you put together fifths in the right way, you end up with the scale: C D E F G A B C. If you play two notes together, that's called an interval. If I play a C and a B together, that interval is almost like an octave, since B is close to the C just above it, but not quite, so it sounds really ugly. But if I play C G B, the C and G sound good together -- a fifth -- and the G and B sound good together -- a major third, which is another interval that kind of lines up -- so the chord doesn't sound ugly. It actually sounds really pretty and sad, because the mind fills in the E, making it C E G B. C E G is a major chord -- happy -- and E G B is a minor chord -- sad -- so C E G B sounds both happy and sad at the same time. On the other hand, C Eb G Bb has C Eb G -- a minor chord -- and Eb G Bb -- a major chord. Since the interval between C and Bb doesn't hurt so much, you hear it, and the Bb sounds like another note in the chord but doesn't make the major chord Eb G Bb stand out. Anyway, the real answer is that nobody knows in general why harmonies sound good, but you can probably come up with some good reasons why a *specific* harmony sounds good. My absolute favorite harmonic moment in music is in Recuerdos de Alhambra, by Francisco T\u00e1rrega -- it's a classical guitar piece (that I can't come close to being able to play yet), and it has a really simple tune with simple harmonies, in A minor. One phrase ends with a G# on an E major chord, and the very next note is a Bb in an A major chord (really an A7b9 -- A C# E G Bb). Why is that SO pretty? I think it's partly because the melody has a very relaxing shape, but mostly it's because the notes G# and Bb don't belong together. You'd expect G# and A#, or Ab and Bb, but not G# and Bb. And at the same time, the interval of A to Bb is a really painful interval that isn't made that much better by the other notes; the G# wants to resolve up to A, but the Bb REALLY wants to resolve down to A. So you're just waiting on the edge of your seat for it to finally get down to A. When you have pretty chords, what usually happens is that ALL OF THOSE NOTES WANT TO RESOLVE AT THE SAME TIME, so you get a lot of feelings at once, plus you like some of the intervals (like major seconds) and they make it even prettier. It's past 4 AM and it's past everyone's bedtime. I made no sense.

Bit of a false premise on that. Your question has 3 pieces, and piece #1 and #3 are related, so let's break those out: > \"How did we make plastic that isn't biodegradable ... out of materials only found on Earth?\" \"Biodegradable\" means that biology breaks it down. I.E. Living things eating it and turning it into... other things. Generally, where the end result is \"dirt\". Dirt itself is quite complicated and isn't a single thing, it's many things. The amount of things that **are** biodegradeable is actually quite small. It has to be something that generally insects, fungus, or bacteria can use as food. Generally, only biological things themselves (plants and animals) are biodegradeable. A sandwich will rot. Mold will grow on and eat the bread which is made from wheat, bacteria will eat the meat and cheese which are made from animals, the vegetables which are grown from the dirt will fall apart on their own without the rest of their plant to keep them together. Insects might eat part of it, or animals. All kinds of stuff. A sandwich was from biological stuff, and it degrades from other biological stuff. ... so... how did we make something that bacteria and fungus and insects and stuff can't eat? Easy. That's most of the entire planet. Like, 99.99999% of the planet. You know how plastic is made. Out of oil. Oil is kinda biological, but nothing really eats crude oil. And, nothing yet has evolved to use plastic as an energy source (food). It's too new. So... plastic isn't made out of plants and animals (not on an human-appreciable scale), and, it's not broken down by plants and animals. But neither are rocks. Neither is a bar of iron. Neither is gold. And so on. So, you could ask the same question about an aluminum wheel as you do about plastic. Why doesn't it biodegrade? Because nothing biological eats up aluminum. So the question of how we can make it is pretty simply answered right there. Next, the middle part of your question: > and is so bad for the planet, Well, what is \"bad for the planet\"? In truth, plastic isn't bad for the planet at all. Landfills in general aren't. \"Landfills filling up!\" protests are generally about distracting from the bigger problems humans are causing on the planet. It gives people a tiny problem to feel bad about and focus on, so that they don't focus on the much worse things we need to stop doing. Landfills fill up. That's what they do. If landfills were emptying, they'd be called mines. Landfills filling up is more of an economic problem, as it's expensive and inconvenient to find new places to seal our garbage away. We used to just dump garbage into lakes and rivers because it was cheapest. Now we use landfills and it's a bit more expensive. When those landfills fill up, the next thing will be a little more expensive again. We will never run out of space, not even close, all that stuff came out of the ground originally. We dig things out of the ground in mines, and then we put things back into the ground and cover them up. No one cares that a rock takes 50,000,000 years to break down, so why do we care about a chunk of plastic or styrofoam in a landfill taking 10,000 years? What harm does it do anyone? How is it any different than a random rock, or whatever else was underneath the ground? ... Well, first, the problem with plastic isn't necessarily that it's not biodegradeable. There are things that do biodegrade that are still \"bad for the planet\", or, \"bad for the plants and animals we like on the planet\". For example, plain old sea salt is really bad for the planet if you dump lots of it in a forest. Everything will die. But salt biodegrades really easily, it's an essential nutrient. Still, if you covered the whole planet in salt, it would kill all plants and animals on the land, for thousands of years. The problem with plastic is... well... we're still figuring that out. We have mechanical problems with plastic, like when birds and animals eat it and it gets stuck in their bodies. And we have beauty problems with plastic, because it's ugly to look at pollution in a park or on a beach. But there are things that might be bad about plastic in very tiny pieces in any animal's body (they're probably not bad for plants). Our bodies weren't designed to have plastic in them, and they don't have much for processes to deal with them. That said, plastics might not do much damage, the whole reason we use them is because they don't really react with anything. ... In summary, there's nothing that says that just because we made something from chemicals in the Earth, that is has to be beneficial to life on Earth, or, that if it's not beneficial it has to biodegrade. Those are each different and unrelated things.","labels":1,"seconds_difference":14610.0,"score_ratio":6.6105263158} +{"post_id":"uvuutm","domain":"explainlikeimfive_test","upvote_ratio":0.92,"history":"Explain like I'm five years old: How did we make plastic that isn't biodegradable and is so bad for the planet, out of materials only found on Earth?

Oil based molecules are already vere very long chains, and plastic is a super long chain. No living creature evolved to break such a complex food because normally food is made of short molecules.

This process is driven by the release of certain hormones, such as melatonin, in response to changes in light exposure. In addition to the circadian rhythm, our brains also have other mechanisms for keeping track of time. For example, our brains can use sensory information, such as the position of the sun in the sky or the sound of a clock ticking, to estimate the passage of time. Our brains are also able to use past experiences to predict how long certain events should take, which can help us keep track of time in the absence of external cues. It's possible that your ability to wake up at a specific time without an alarm is due to your brain's ability to keep track of time using these mechanisms.

This creates the neural pathway that tells the brain to react. For instance, when you have a phobic response (let\u2019s say that you saw a snake under your bed) your body would release cortisol in combination with adrenaline. The compounds would course through your blood and the re-uptake would begin to affect the necessary bodily functions ( i.e. increased heart rate, sweating, shutdown of the digestive system, tunnel vision, blood pushed from the skin and extremities to the core and to the legs. ) this attunes your body for the fight or flight response. These side effects are good if you have a real threat. Skin turns into a sort of armor, vision is concentrated on the threat and not concerned about the surroundings, large muscles have increased blood for combat or flight, etc. This is not so good if the threat is not as pertinent. Let\u2019s say you have to get up in front of the class and give a presentation. Same or similar phobic response, but not so useful. Pale sweaty skin, butterflies in the stomach, dry mouth, and crapping your pants is less than ideal in this circumstance. The hormone dump will continue as needed, until the threat is eliminated or the tank is empty. Because this is not an electrical impulse from the brain, but a hormonal response, it lingers in the system until the re-uptake is complete. It will gradually fade. As was previously mentioned anti-depressant medications are typically re-uptake inhibitors that cause the re-uptake to be delayed and for the dopamine and serotonin to linger in the system. The drugs don\u2019t create the good feelings, so to speak, they just cause them to spread out and last a bit longer. Most illegal drugs that are recreationally used cause the body to artificially dump dopamine (and serotonin in the case of X) which flood the system. The re-uptake is hitting all the nodes at once causing euphoria. Some of the nodes are damaged in the process which is why you typically get diminishing returns.

Adrenaline, made in the interior of the adrenal gland, is a molecule called a 'catecholamine'. I only mention it if you want to do more reading. After it stops getting secreted, it gets absorbed in nerve endings and broken down into its basic building blocks, by two different enzymes.

This creates the neural pathway that tells the brain to react. For instance, when you have a phobic response (let\u2019s say that you saw a snake under your bed) your body would release cortisol in combination with adrenaline. The compounds would course through your blood and the re-uptake would begin to affect the necessary bodily functions ( i.e. increased heart rate, sweating, shutdown of the digestive system, tunnel vision, blood pushed from the skin and extremities to the core and to the legs. ) this attunes your body for the fight or flight response. These side effects are good if you have a real threat. Skin turns into a sort of armor, vision is concentrated on the threat and not concerned about the surroundings, large muscles have increased blood for combat or flight, etc. This is not so good if the threat is not as pertinent. Let\u2019s say you have to get up in front of the class and give a presentation. Same or similar phobic response, but not so useful. Pale sweaty skin, butterflies in the stomach, dry mouth, and crapping your pants is less than ideal in this circumstance. The hormone dump will continue as needed, until the threat is eliminated or the tank is empty. Because this is not an electrical impulse from the brain, but a hormonal response, it lingers in the system until the re-uptake is complete. It will gradually fade. As was previously mentioned anti-depressant medications are typically re-uptake inhibitors that cause the re-uptake to be delayed and for the dopamine and serotonin to linger in the system. The drugs don\u2019t create the good feelings, so to speak, they just cause them to spread out and last a bit longer. Most illegal drugs that are recreationally used cause the body to artificially dump dopamine (and serotonin in the case of X) which flood the system. The re-uptake is hitting all the nodes at once causing euphoria. Some of the nodes are damaged in the process which is why you typically get diminishing returns. Because of the flood of neurotransmitters in the system, complete re-uptake cannot be achieved and some will be flushed from the body. With continued use the tank will eventually be empty and further use of the drug will not have the desired effect.

Just as plucking a long, fat string creates a different sound than plucking a short, thin string (think of a thin string on the same guitar that you've maybe shortened by pressing on a fret), speaking with big fat vocal cords produces a different sound than speaking with short skinny vocal folds. This, for example, is how you change pitch. Not only your vocal folds, but the rest of your vocal tract is specific to you, so your voice resonates differently. Think of your vocal tract (pharynx, nasal cavities, cheeks, hard\/soft palate) as the body of your guitar. What happens AFTER you pluck the string? It resonates off the guitar walls, and will do so entirely differently off ukelele walls or banjo walls or whatever walls that are different shapes and sizes. Your voice does the same off your cheeks, palate, pharyngeal walls, etc. So that's a very simplified description of anatomy.

Meaning we can (to some extent) not only choose our pitch with our vocal folds, but we can adjust somewhat the shape of our vocal tract and articulators (as though we could change the shape of our guitar body in real time while we are producing sounds). For example, you can move your velum and push your voice to be more nasal, vibrate lower down to to have more glottal friction, move your tongue to make sounds more palatal, make certain sounds more dental or alveolar by moving the tip of your tongue. If you do this in very specific ways (changing, say, the shape of your vowels or altering the manner of articulation of certain consonants) you can even create specific patterns of phonemes that we identify with different \"accents\".

The difference is in how the carrier wave is modulated, or altered. With AM radio, the amplitude, or overall strength, of the signal is varied to incorporate the sound information. With FM, the frequency (the number of times each second that the current changes direction) of the carrier signal is varied. FM signals have a great advantage over AM signals. Both signals are susceptible to slight changes in amplitude. With an AM broadcast, these changes result in static. With an FM broadcast, slight changes in amplitude don't matter -- since the audio signal is conveyed through changes in frequency, the FM receiver can just ignore changes in amplitude. The result: no static at all. ----------------------- From: http:\/\/www.cybercollege.com\/frtv\/frtv017.htm AM also limits the loud-to-soft range of sounds that can be reproduced (called dynamic range) and the high-to-low sound frequency range (called frequency response, to be explained below).","human_ref_B":"Due to the way they are implemented, FM transmission has shorter range but has better sound and is also usually in stereo.

Then to make things worse, it turns out that making good AM radios that can get the whole (half) range being transmitted is way more expensive than making crappy radios that get only the bottom half of that range, so most AM radios are in effect only playing a quarter of the frequencies that are in the original music being transmitted. Good sound has frequencies up to about 20000 Hz, but the stuff coming out of your AM radio receiver only goes up to about 5000 Hz. No wonder AM sounds bad! For various technical reasons, FM radio doesn't have this problem nearly as much, so it sounds better (it can go up to about 15000 Hz.) **ELI20 version:** Modulated radio transmissions like the ones broadcasted by radio stations, have a main carrier frequency - say, 99.1MHz in the FM band, or 1550kHz in AM - that you tune your radio to in order to listen to a given station. However, the process of modulating the radio signal (i.e., embedding audio information into the carrier) puts energy at frequencies above and below the main carrier, in its so-called \"sidebands.\" The higher the audio frequency being transmitted, the wider the sidebands become. So if a radio station transmits a 1kHz audio tone on a 1000kHz carrier, the signal going out will actually have energy between 999kHz and 1001kHz (the carrier frequency, plus and minus the audio frequency.) Play a 10kHz tone, and the signal will now have energy between 990kHz and 1010kHz. Play a full-spectrum (20 - 20000 Hz) music recording from a CD and your transmission will now have energy everywhere between 980kHz and 1020kHz. The important thing to grasp here is that **the higher the audio frequency being transmitted, the wider the sidebands become.** So if two stations are transmitting at carrier frequencies that are too close, like 1000kHz and 1001kHz, their sidebands would probably overlap and interfere with each other. It would make it impossible to tune into one station without getting a little bit of leakage from their neighbor station. To resolve this issue, every station's carrier frequency would have to be far enough away from the others to allow their sidebands to coexist without overlapping. But how far? Well, for various historical, technical and regulatory reasons, a compromise has been reached in which the FCC requires AM stations to limit the highest audio frequency they broadcast to 10.2kHz (i.e., cutting out all audio content above 10.2kHz and thus reducing sound quality) therefore putting stations that serve the same geographical area at least 20.4kHz away from each other (30kHz or more, in practice.) So AM radio stations broadcast bandwidth-limited audio that's missing all of its high frequency content above 10.2kHz. But that's not the whole story: AM receivers can be made simply and relatively cheaply, but these cheap receivers have even worse frequency response than the already high-frequency-limited AM transmissions (they only go up to about 5kHz.) It turns out that making AM receivers that can reproduce the whole audio spectrum is expensive, so most AM radios on the market only output sound in the 50 - 5000 Hz range, or so. That's a long way away from the 20 - 20000 Hz range that most people can hear, so it sounds boxy and muffled and just plain bad. FM stations are also required to cut high frequency audio from their broadcasts, but only at 15kHz.

Edit: If your question was about the actual act rather than the question of \"why don't we do this\" then imagine a series of three metal bars, connected in a line with lockable joints. Now lock the joins so the metal bars form into a stiff shape and imagine another group of bars but with unlocked joints. If you put a lot of impact onto it, the energy has to go somewhere. The energy doesn't simply dissipate into thin air. If the impact is hard enough, it can overcome either the strength of the locks or material strength of the bars, breaking them. but if they are unlocked, the system deforms (in a way that's easy for it usually) absorbing some of the energy. The act of deforming absorbs energy. Your body, your bones and joints, are that system. When you tense up, you lock up your locks and the impact force either breaks those locks, or your bones. If you're not tense, then your body \"deforms\" (your arms bend, your legs bend, you bend your torso) and since the human body is generally *a lot* more elastic than people are comfortable thinking about, your body does a decent job of absorbing most of the energy in a relatively safe way.","labels":1,"seconds_difference":5907.0,"score_ratio":6.8461538462} +{"post_id":"5ixmmr","domain":"explainlikeimfive_test","upvote_ratio":0.89,"history":"Explain like I'm five years old: Why during a car crash or any accident do we get hurt more from having our muscles tense?

Exploding Dots is a visual way to teach base systems in math. We work in a base 10 system (think place value!), but there are other base systems. Binary is base 2, time is base 60, etc. Practicing working in other bases improves number sense (which is your innate understanding of numbers and how they interact). James Tanton is an Australian Mathematician and teacher, and he created this concept. In a practical sense, it works much like an abacus or counters. You use a \u201cdot\u201d to represent the value \u201c+1.\u201d Using the dots and the 1<-10 (read \u201cten one\u201d) machine, you can visually replicate how various operations work. If you draw 2 dots and add 3 more dots, you can visually see there are 5 dots (2+3=5). If you draw 10 dots in the right-most box in the machine they \u201cexplode,\u201d and this creates a single dot in the box one to the left. This is how we visually represent 10 dots, by having every dot in the second box be equivalent to 10 dots in the first box, every dot in the third box be 100 dots, every dot in the fourth box 1000 dots, and so on. Through slightly more complicated procedures, more operations can be represented using dots and machines.

Thanks for bringing this to my attention... And to anser the question, it's just a visualization of what you learned for basic arithmetic. Instead of a take over you got the exploding dot... It can help to make implicitly patterns explicit and show you what you are actually doing...

Exploding Dots is a visual way to teach base systems in math. We work in a base 10 system (think place value!), but there are other base systems. Binary is base 2, time is base 60, etc. Practicing working in other bases improves number sense (which is your innate understanding of numbers and how they interact). James Tanton is an Australian Mathematician and teacher, and he created this concept. In a practical sense, it works much like an abacus or counters. You use a \u201cdot\u201d to represent the value \u201c+1.\u201d Using the dots and the 1<-10 (read \u201cten one\u201d) machine, you can visually replicate how various operations work. If you draw 2 dots and add 3 more dots, you can visually see there are 5 dots (2+3=5). If you draw 10 dots in the right-most box in the machine they \u201cexplode,\u201d and this creates a single dot in the box one to the left. This is how we visually represent 10 dots, by having every dot in the second box be equivalent to 10 dots in the first box, every dot in the third box be 100 dots, every dot in the fourth box 1000 dots, and so on. Through slightly more complicated procedures, more operations can be represented using dots and machines.

Insulin regulates the uptake of sugar and the higher the insulin the more sugar is converted into fat. Additionally, you can develop a resistance to insulin which is known as type 2 diabetes.

This happens because of some mutations\/changes in the Gene of a cell. Normally, a cell can divide only a given number of times. But cancer cells have no restrictions. They are basically immortal. That's what makes them dangerous. Now during cell cycle (or division), the following events occur: 1. G1 Phase 2. S Phase 3. G2 Phase 4. M phase Step 1-3 are just the steps in which cell just prepares everything it will need to divide. And these steps together are called Interphase. 4th step is where the cell actually divides. These events are controlled by a very complex mechanism of chemical interactions which are guided by the gene of a cell. And in the cancer cells, these mechanisms fail. Now after G1 phase, if a cell decides it doesn't want to divide into two daugter cells, it enters a stage called G0 phase. The cell exits from the cell cycle. The cell doesn't divide. Now however, if the cell is past the Sphase, there is no going back. Because in S phase duplication of Genetic material(dna) occurs. If a cell has any more dna than normal, it has to divide. There is no other way. Now that we know all this, the answer to your question is pretty simple. Heart cancer is rare because heart cells do not divide. They are in G0 phase. They are out of the cell cycle. And for cancer to occur, uncontrolled growth(division) of cells is a requirement. Neurons also don't divide and are in G0 phase. Hope this helped.

Since water in a cup is \"all together\" when it freezes, it'll freeze into one big crystal, like an ice cube. When water is in a cloud it's molecules can be so far apart that when they freeze they'll form a single crystal, a flake of snow. Here's the complicated bit, cold air can't hold much water. So a \"cloud\" of snow in really cold weather isn't dense to begin with, there just *isn't much water there* in the first place, and the moister that is there is really far apart. So when the crystals freeze and drop from the sky, you get snow. If the air is warmer it can hold more moisture, which means there is A more water in general and B the water is closer together. This means larger drops can form, and then freeze, into larger crystals and you get sleet, icy rain. Finally, sometimes you can get a weird process where snow or sleet can freeze, start falling, then get pushed back up into sky by wind where it gets wet with more water\/sleet which freezes, gets heavy again and falls again, then gets blown back up and process repeats and you end up getting *big* chunks of sky-ice. That's how hail forms. So in the end the difference between getting rain, sleet, snow, or hail is a complex mixture of a few variables - how much moisture you're starting with, how different layers of hot\/cold air pockets stack up and interact in the sky, and how the big\/small the water droplets are that you're starting with, and what happens to them from cloud to ground.","human_ref_B":"Ice of any sort (ice blocks, sleet, snow, etc) is basically water molecules cooling, and holding still. Because water molecules are polar (think a magnet with a north and south end), they like to bind to each other. When water molecules get cold, they act in an interesting way based off of the molecular shape, and start to form crystalline structures, and start sticking together in a fairly standard pattern (ice). In your freezer, the water is not being agitated, and these structures, or lattices, can continue to form, creating solid blocks. In the atmosphere, these molecules are constantly being moved, so only little crystals can be made (snow). If you get convection (warm air rising, cold air falling), and get water molecules to rise and fall several times through an ice-forming environment, you can potentially get larger crystals (hail, etc). You also have to remember that atmospherically, the temperature falls roughly 4 degrees F for every 1000 ft, and you generally get more convection in warmer parts of the year. Take those two facts, and that\u2019s why you get more hail in the summer, etc. In winter, there just isn\u2019t enough convection to keep water molecules in the air, and they just fall as snow","labels":1,"seconds_difference":163.0,"score_ratio":2.5} +{"post_id":"kwu2qc","domain":"explainlikeimfive_test","upvote_ratio":0.9,"history":"Explain like I'm five years old: Why does light have a finite speed?

Note, however, that each type of cancer is staged differently. A doctor takes the whole picture into account, so *please take these with a grain of salt.* > Stage 0 \u2014 A small tumor that has not affected any nearby tissues. Cancer at this stage can typically be fully cured by surgically removing the tumor. > Stage 1 \u2014 The cancer hasn\u2019t spread to other body parts, but nearby tissues are impacted. (For example, there might be cancerous cells in the tissue immediately surrounding the tumor or primary cancer site.) > Stage 2 \u2014 As soon as the cancer spreads to another body part, it becomes Stage 2. In this stage, the spread is still local, usually limited to the organs right next the the primary tumor. Occasionally, cancer that has spread to the lymph nodes is staged here. > Stage 3 \u2014 Like Stage 2, this is usually limited to fairly localized cancer spread. In this stage, however, the regional spread is more advanced. This stage also includes significant spread to the lymph nodes. (Lymph nodes matter because cancer cells could *potentially* travel through your lymphatic system to other body parts). > Stage 4 \u2014 Sometimes called metastatic cancer, this stage is usually reserved for advanced cancer that has traveled to distant body parts. \u2014\u2014 **LIFE EXPECTANCY** This is pretty straight forward: life expectancy is just a game of statistics. The doctor determines your type of cancer, stages it, then looks at data for other people who had the same diagnosis. They basically take the average of the lengths of time these other people lived and bam, there\u2019s the life expectancy. Sometimes it\u2019s a little more complicated than that, but the most important takeaway is that **life expectancy is *not* a prediction\u2026it\u2019s a guess.** Some people die sooner, some die shortly after, and other people outlive their life expectancy by several years.

This is going to be based off of data comparing other people who have had a similar cancer and their outcomes. Now what does the survival rate actually mean? Well, even when an early stage cancer is treated, there is a possibility that cancer cells were missed, or had already spread in your body. Even when treated, there is a decently high chance that the cancer was never fully defeated, and it will take a certain amount of time to grow back from individual cells into something that actually kills you.

The source of water in the large part determines the final product of the water. Most municipal water districts are charged with making water safe to drink according to governing body regulations. Two typical types are surface water and well water. Surface water is lakes, rivers and streams. Well water is typically an underground aquifer. Surface water: the turbidity, alkalinity and metals naturally found in the source water can have significant impact on the final product. For example, the end of the Mississippi River is very turbid(dirty) and contains many naturally occurring metals including iron, lead and manganese. The water must go through a clarification process ( to remove the dirt) typically by way of an up flow clarifier and sanitation by way of chlorine, bromine, ozone or uv treatment. In some water treatment plant a the water is so contaminated with human and animal waste extra steps are taken by adding ammonia with bleach\/chlorine to make chloramine. It gets the biologicals associated with poo poo out if you will. Surface water can be a great source however. Some lakes are so clear and have a high alkalinity that add to the quality and taste. These sources typically do not need much processing such as clarification and only slight sanitation to stay within governing body standards and to ensure it gets to the tap safe to drink. Well water: this is usually the best source to gather water for human consumption. The water trickles through layers of sand and rock making its way to aquifers. Some of these sources are safe to drink with no processing, however large quantities of hardness in the form of calcium carbonate (think limestone, the white stuff that forms on the tap or basin\/tub ring) as well as magnesium based species. Some well water systems have some amount of biological activity even without the presence of oxygen and must be treated accordingly. Most cases, these anaerobic bacteria are harmless to humans. All sources of water can have some amount of entrained gasses. This can be from the source, from processing or from distribution of potable water. In some areas where building a water tower is out of the question and large high pressure distribution pumps are not economical, tanks with a cover gas may be used. This ensures the service area will have a steady pressure and will act as a surge volume during times of heavy demand. These tanks with a cover gas will absorb some amount of air and will off gas when exposed to the atmosphere. In some cases methane or natural gas can enter the water and off gas at the tap as well. This is usually caused by man-made activities. As others have said, The bubbles you see could just be due to the aerator on the faucet. The taste of the water directly after filling a glass has all these items to take into account. In some cases leaving a glass of water out will slowly become more acidic by way of absorbing carbon dioxide gas. The source of your water directly impacts the quality of your water regardless of treatment. Garbage in equals garbage out. I no longer drink surface water in South East Louisiana even if it's been through an reverse osmosis process. The Mississippi River is the nation's sewer and the more I learned about water the more I began to fear what I was consuming. Hope this helps.","human_ref_B":"Those tiny bubbles in your glass are a result of something called Nucleation.

If you want some historical sources of thought on this topic, check out book IV of Aristotle's Meteorology (despite the title, the fourth book is actually not about meteorology at all). Aristotle discusses at length the way that different terrestrial bodies can change and be changed. He didn't have a theory of fermentation per se, but it and a number of other processes (digestion, cooking, smelting) are considered to be part of the same family of processes. You've got to think about things in terms of bodies with certain properties having their properties changed, not in terms of atoms. Fermentation is just another way by which people can change the properties of certain bodies. Much later, the great alchemist Paracelsus also writes about fermentation as an analogue for the elixir of life. For him, yeast and other agents of fermentation just have a special preservative property to fix things in their current state. This kind of thinking is common in alchemical and non-alchemical texts alike - all the things in nature just have special god-given properties, and it's up to the clever alchemists to find them. Paracelsus says: >\"We call this preservative an elixir, as if it were yeast, with which bread is fermented and digested by the body. Its virtue is to preserve the body in that state wherein it finds it, and in that same vigour and essence. Since this is the nature of preservatives, namely, that they defend from corruption, not in any way by purifying, but simply by preserving. The fact that they also take away diseases is due to the subtlety which they possess. So, then, they do not only preserve, but they also conserve. They have a double labour and duty, that is to say, to prevent diseases and to keep the essence itself in its proper condition\" > >\\- Paracelsus, *The Archidoxies of Theophrastus Paracelsus*, Book 8, *trans*. Waite Essentially, some stuff just has the power to act on other stuff in a way that preserves it. This isn't all that weird on an ancient or early modern worldview. Some rocks just have the power to attract iron! Some plants have the power to induce vomiting!

Instead, it was more natural to accept things as they are and not ask questions that couldn't be answered anyway. God knows best. Ancient philosophers and medieval alchemists were members of the higher layers of the society - they had time and resources to ponder those questions, but often they treated it as a hobby and were coming up with fantastic theories instead of something resembling science. Those who really tried were few and far between. So even though we know about people like Archimedes, Galen, or Avicenna, who were rigorous in their studies, their methods didn't get popular recognition.

The property of primes you have to know is that every single number has only one so called \"prime factorization\" which just means that if you only multiply prime numbers, there is only one combination of those prime numbers that gives you your original number. Example 1: 17*47=499. The only way you can get 499 from prime numbers is by multiplying 17 and 47. Example 2: 2\\*2\\*2\\*19=152 is the only way to multiply prime numbers and get 152. Etc. You can do that for every number. The trick is that while it's \"easy\" to multiply numbers together, it's incredibly hard to reverse it. Like, try to find the prime factorization of 2455. (Actually don't try, it's not going to work, it's 5*491) You basically have to go through every prime number one by one, and multiply them to find out what it might be.

Imagine them as little billiard balls that can flow through things quite well because they are really tiny. An important property of these balls however, is something called an electric charge. An electron has a negative one and a proton has a positive one. Depending on the specific case, there can be many grouped charges, like when electrons build up in lightning, or dispersed throughout like in everyday materials. It can also flow through things quite well, depending on the environment and how well they're held in place \"normally\". In the case of water, let's say it's coming from a cloud in the sky as in lightning. You can picture it as the cloud holding a bucket of electrons and suddenly pouring out once it reaches its maximum limit. These balls coming crashing down at a high speed and strike the water. At that instant, the balls crash down and possibly causing the water to evaporate, dissociate, and ionize. You can picture this as billiard balls violently crashing down into a ball pit. They will crash into things, causing all sorts of mess. After the initial strike, the balls tend to flow away from one another because like-charges repel via the \"Coloumb force\". This really just means that they don't like to be together unless there are conditions that favour it, like the ones that occur when building up in the clouds. Once they are in a relatively \"free\" environment in water, they will disperse around that area, preferring to go in directions where there are less electrons around. If the water is really shallow, this is probably just going to be the ground. If it's deeper, like the ocean, it will probably take a longer while before it reaches \"ground\", or any kind of electrical sink, which acts to \"take in\" all of the extra charge. The electrons eventually \"stop\" or at least, in a manner that we count as electricity, when they crash into something, react with something, or get absorbed into something. The electricity requires something to interact with it in order to \"stop\" or disperse effectively. It will stop acting as the \"electricity\" that we consider as a consistent current (the stream of balls falling) soon after the strike, since the balls will find themselves running away from each other very quickly, crashing into things as they go.","labels":1,"seconds_difference":10873.0,"score_ratio":1.0909090909} +{"post_id":"ym8yrn","domain":"explainlikeimfive_test","upvote_ratio":0.92,"history":"Explain like I'm five years old: at what point does electricity stop in water?

You're implying that when we put \"electricity\" into the water, it already goes somewhere, and that there is a point at which it \"stops\" going somewhere. This is kind of true, but not in the way you think. Everyone else has explained why it's not true, so I'll explain why it is true. For those who understand electric current, ignore all sign convention because it's confusing and unnecessary for the basics. To \"electrify\" a body of water, you have to either put electrons in or take electrons out on a large scale (since that's basically what electric current *is*, the movement of electrons) which will then spread out and push each other (and other electrons in the water) away from each other. With the extra \"oomph\" from the current injection (the voltage) there will be a new steady state: either the electrons will find a new place to go (for example the earth or the other terminal of the battery) or, if there is not a place for these electrons to go, then eventually they will bunch up and push back against the source of electrons that's trying to push them into the water (and a higher voltage source can push more electrons in. This is essentially a capacitor, and the key difference between a capacitor and a battery; a capacitor stores electrical energy and a battery stores chemical energy that it converts to electrical energy.) The electricity \"stops\" when the electron injection gets so far away from you that it can't have a major impact (like sunlight getting dimmer and dimmer the farther away you get in space.) Things get pretty confusing because we usually say electricity \"has\" to go back to where it came from to \"complete the circuit,\" but this isn't strictly true, and we take advantage of this all the time (it's called a \"floating ground\" or a \"floating potential\" if you're curious.) The earth is so large that we can treat it as both an infinitely large sink and source for electrons for all conventional purposes, which is why we use it as a global connection for everything (\"earth ground.\") However, if you don't provide a path for the electrons to return to the source, then you aren't replacing the electrons, and the electron source will eventully have its own force trying to pull the electrons back in, meaning it will get weaker over time as it gets harder to push the electrons out while they get pulled back in.","labels":1,"seconds_difference":384.0,"score_ratio":12.0} +{"post_id":"ww9xv6","domain":"explainlikeimfive_test","upvote_ratio":0.8,"history":"Explain like I'm five years old: How was the Soviet Union, despite being so poor that people were starving to death in famines, rival the US for the better part of a century?","c_root_id_A":"ilkfv5l","c_root_id_B":"ilk7se9","created_at_utc_A":1661327654,"created_at_utc_B":1661321419,"score_A":153,"score_B":42,"human_ref_A":"The Soviet Union had no famines after 1947, and they only had one that late due to the after effects of WW2.

Uranium is a relatively stable element that lasts for a long time and emits very little radiation. Uranium nuclei have an *extremely* low chance of decaying at any given moment compared to other radioisotopes; it takes billions of years for a sample of Uranium-238 to decay by 50%. Radium, on the other hand, takes anywhere from a few days to 1,600 years to decay by 50%. Since its nuclei are much less stable, it emits far more radiation, making it potentially dangerous. Radium also creates Radon (a radioactive gas) when it decays, which can accumulate in poorly-ventilated underground spaces and significantly increase your risk of cancer.","labels":0,"seconds_difference":485.0,"score_ratio":1.6666666667} +{"post_id":"1pa1rm","domain":"explainlikeimfive_test","upvote_ratio":0.81,"history":"Explain like I'm five years old: If our cells are always dying and being replaced how does a tattoo last forever?

This layer is not only much more inner than the epiderms (outermost layer), it's also heavily inundated by immune cells ready to fight foreign infections. When the tattoo ink is injected into the dermis layer, immune cells such as macrophages will immediately want to eat up or phagocytose these droplets because they are foreign in nature. The simple way of understanding it is that these immune cells cannot eat up the ink droplets due to their size in nature and will start to aggregate around the ink droplets. The ink then becomes trapped in these aggregates of immune cells that will almost indefinitely stay in the region. These aggregates will continue to stay in the region despite cellular proliferation around them.

This made sense back when cars were fairly new to the mass market. Regular garages and auto shops were more capable of dealing with service needs (since they were plentiful) than the manufacturer itself (which was only concerned with cranking out more cars, not fixing existing ones). Furthermore it was actually more stable for car makers at the time. A dealer would order in bulk and those sales were guaranteed for the maker. The issue of actually selling to a consumer was no longer the auto makers problem. Since the only way for common folk to spread information back then and until recently was just word of mouth haggling was the standard and so was mark up. It was really hard to find out information. There is less need now since most manufacturers do not void warranty if service is done outside of a dealership and haggling is a pain in the ass, but the buyers have the internet at their disposal to give them the upper hand. Tesla already sells directly to the consumer. You can enter a Tesla showroom, test drive, build and price your car, place the order and some time later your Tesla shows up at your door. Some independent dealers have experimented with this model as well with good results. Since dealerships are responsible for selling they get to set the price, the difference between what they paid for the car and what you pay is profit for the dealership. As for price. Cars can be highly customized and even the cheapest car can cost a lot with every single option picked out. The reason the base price is usually much cheaper than the average build is that the most desirable features come with a huge price. I could, for example buy a Chevrolet spark for 10,000 dollars or so and pay only that. But that doesn't even get me air conditioning. To get AC I need to spend an extra 3000 on the next trim level (AC doesn't come as a standalone option). This is a common thing among automakers because AC is THAT desirable. Also those who can't or don't want to drive manual need to spend an extra 2000 on the automatic transmission. Add a few more bits and things and the final price rises. Also you need to pay a destination fee (cost to ship your car to the dealer) and by federal law this is required to be the same for all dealerships throughout the country, no matter the distance from the plant. Then if you got the AC you have a mandatory AC fee which is used to cover the costs of scrapping the AC when the car is eventually junked. After All of that you pay the standard sales tax which varies based on where you live. If you aren't paying cash you are likely going to get hit with fees for financing. It is possible though to walk into a dealership, buy the cheapest possible car at the advertised price, paying only destination and tax with cash upfront, and walkaway not \"cheated\". Maybe haggling isn't so bad after all. PS: the MSRP on a car isn't it's exact price of what the dealer pays the maker.

Or 10k volts per centimeter. That means that on the highest 330kv lines, you only need the cables to be at least 33 cm apart.. And they make sure that the earth cable (usually the single cable) is the closest cable...and that other cables are at least a meter away. Next, when the cables pass a transmission tower, the insulator that holds the cable up is at least a meter long... And there's a cable that jumps the join, so the path of least resistance is always away from the tower. Next, the single most common mode of failure for hv lines is that they oscillate when struck by strong gusts of wind.. ^1 Which is why cables in exposed areas are either bundles of cables separated by plastic spacers, or have large plastic \"football's\"on them to stop resonant vibrations. ^1 The cables on one side \"skip\" one way, and the cables on the other in the opposite direction, and in some cases get close enough to touch... So you make sure they are under enough tension they don't touch, or don't oscillate. The next most common reason for hv line failure is either joint failure.. The cables have to be joined at some point, and the joins fail because the cable is flexible. You can spot the fault with a thermal camera, and the fix is simple. (Cut, weld)... Or bird damage. Big Bird lands on cable, stretches wing, gets close enough to next cable for the voltage to jump.. And the arc runs away.","labels":1,"seconds_difference":1570.0,"score_ratio":1.1739130435} +{"post_id":"yqaap4","domain":"explainlikeimfive_test","upvote_ratio":0.71,"history":"Explain like I'm five years old: Why are stars and planets named with weird combinations of letters and numbers?

Let's say Mom has been super irresponsible lately; basically she's being a bad mom. All of her children have left the nest, so to speak, but she's trying to keep tabs on them. In her eyes, she's doing the right thing -- as a mother she's worried about her children, and she's trying to look out for their best interests. How can Mom protect her children without knowing what to protect them from? Mom knows what scary things are out there better than her children, or so she tells herself. So since she knows better, she thinks she's justified in keeping tabs on them. Only, in this family, the way she's keeping tabs on her kids is illegal, and some of the things she's been doing with other families has been questionable. Edward, a bit of a Momma's boy and so hangs out with her a lot, sees what Mom is doing. Heck, Mom even asks Edward to do some of it for her. And Edward thinks to himself, \"Mom, this ain't right.\" But telling his mother won't solve anything. She knows what she's doing, and she knows that it's wrong. She won't stop. So Edward decides he has to tell some of the other kids what Mom's been up to. He's very concerned about how Mom keeps tabs on them because it isn't right, and if she won't tell them what she's been doing... well then, by golly, Edward will!

Which, of course, is true, but his disobedience only makes Mom more upset with him. How *dare* he stay outside and play with the other kids. And look at that, he's even hanging out with a new family, one of Mother's enemies! Mother wonders if they've adopted him.

You cannot decrypt using the same key it was encrypted with. To simplify it we will use a substitution cipher. The most basic of all ciphers\/encryption. The \u201cA\u201d key will increment each letter by +1. So D -> E, E -> F, and so on. The \u201cB\u201d key will increment by -1, so P -> O.

The keys generated are complex enough to avoid collision, or when someone else\u2019s key pair might accurately decrypt your message. Ok, now that we have our keys, we always keep one secret and only known to us, the private key. Use encode the message we want to send using our Private key(A).

Now that we have exchanged keys, and have a secure method to exchange messages, anytime I want to send my friend a message, I encrypt it with their Public B key, which ensures only they can decrypt it with their private A key. The problem is asymmetrical encryption like this is slow. Using the secure exchange we setup we mutually agree to start using a symmetrical encryption method and generate a key to use (Key C). Symmetrical encryption uses only one key for both encryption and decryption, and is much faster than asymmetrical. Going forward we can both just use Key C to encrypt our communications. What\u2019s cool is that even if someone got an exact copy of that first message, it doesn\u2019t matter.

Fusion plasma is basically the Universal Solvent, able to dissolve any known material due to the insane temps and pressures... and this includes its container. There's a couple strategies. The first is magnetic confinement. Basically it's held in place by a magnetic field, so the plasma never actually touches anything physical. This comes with its own set of problems. First, there's a tremendous number of neutrons that are still flying off and crashing into the walls which still degrades them. Next, shape of the magnetic field is very important. That's why some varieties are really strange looking. Finally, you need really strong magnetic fields and the way to make the strongest magnet fields is to cool down the magnetic materials to near absolutely zero. But think about that... now you have to maintain the temps and pressures of a star mear centimeters from materials at near absolutely zero. And people wonder why fusion is perpetually 20 years away. There are other strategies to contain the plasma though, that approach it in different ways. General Fusion has revived an old idea. Basically they surround a sphere with really strong pistons and all those Pistons are coordinated to slam into a liquid metal medium (I think they're using lithium) which concentrates and focuses the shockwave onto a tiny bit of material at the very center. Each time there is a pulse the material undergoes a burst of fusion. The liquid metal then absorbs the bursts of heat and can be circulated to extract the heat from the pulsing bursts of fusion. This way your container walls never go bad because you can continually flow more liquid metal in as needed. I'm sure there's other strategies, but these are the two I'm most familiar with.","human_ref_B":"Fusion will be like a jet engine. Jet engines take power from the fire and use most of it to keep the engine going. Then the left over power pushes the airplane.

Fusion generators will use most of the electricity they make to keep the fusion engine safe. Strong magnets will keep the tiny little ribbon of heat in the middle of a box while other machines take the heat away to make electricity.

Breaking down a pound of oxygen this way would require the *input* of at least that much energy: it's roughly that of a small nuke even if you were running the reaction at 100% efficiency.","human_ref_B":"All matter is made of atoms. There are 92 kinds of atoms which are natural and half a dozen which are man made. Atoms are made of protons, neutrons and electrons. The number of protons an atom has determines what element it is. For example, Hydrogen is hydrogen because every one of its atoms each has a single proton. Elements can be turned into other elements but not using chemistry. Alchemists tried to turn lead to gold, but failed. This is because it takes more energy than can be gotten from chemical reactions. To truly turn one element into another, nucleur energy is required. This is a physical change, not a chemical one. Elements being created and destroyed is a very common phenomenon. The most obvious example is the sun. The sun's gravity is so enormous that at its center atoms of Hydrogen are so comprerssed that their protons combine. This destroys the Hydrogen atoms and a new atom is created, Helium. Helium is an atom which has two protons. The sun can also make even bigger atoms. Carbon has 6 protons and Iron has 26. However, Carbon and Iron are much harder to compress and it takes much more energy to create them. In fact Iron is so hard to make the sun can't make atoms any larger than Iron. Bigger atoms get made when really massive stars explode in an event known as a supernova. The star blows itself apart and this provides the energy needed to makd Iron into bigger atoms like Iodine, Lead and even Gold. All the Gold on earth was formed when a hudge star exploded many billions of years ago. The dust cloud eventually re-condenced into the earth and sun. When stars makd bigger atoms out of smaller atoms it is called nucleur fusion. There is another way to make new atoms and it happens right here on earth. Uranium has 92 protons and this makes it very unstable. Uranium atoms can fly apart into two pieces if hit by subatomic particles. This is how a nucleur generator and atomic bombs work. This kind of reaction is known as nucleur fission. Unlike nucleur fusion, the exact kind of new atoms are impossible to calculate. When big atoms split, it is like breaking a rack of pool balls. There is only probabilities that certain new atoms will form. Most of the time the two new atoms get roughly half the number of protons each, but it is not exact. These new atoms are called nucleur waste or nucleur fallout. Strontium, Iodine, Xenon and Barium are the kinds of atoms which form when Uranium splits apart.

I understand that weight could be an issue, but if you divide it up into multiple batteries that weigh no more than say 20lbs each, that would be manageable and allow the average person to be able to change it out (or you could use attendants). Seems a system like this would allow you recharge as quickly as you can currently gas up.","c_root_id_A":"d6k99x1","c_root_id_B":"d6k419q","created_at_utc_A":1471382279,"created_at_utc_B":1471375653,"score_A":4,"score_B":2,"human_ref_A":"As someone who has changed out batteries in Chevy Volts and Cadillac ELRs I can tell you that it is not an easy process. There are a ton of safety measures that they make us follow. We have to have special gloves to handle any of the high voltage system. We have a special table fixture that we use to lower the batteries out of the car. Once the battery is out of the car, it is still in a special sealed box that has approximately 100 bolts holding it together. Once you have the bolts out, you have access to the actual batteries. There are 4 sections to the battery that you can replace. Each section has 30ish cells in it. If you wanted to replace 1 of those sections, you have to disconnect everything and go through all the same safety procedures and checks. You can then physically replace the section. Once you have installed the new section, you hook all the connections back up and install a battery \"balancer\". It balances the charge across all the sections so they all have the exact same charge which is important due to the face that a .1v variation will set a code in the computer. After all that, you put the lid back on the special box and perform a pressure test to check for air leaks. You can then install it back into the car and hook everything back up, again following the safety procedures. All in all, it can take anywhere from 4 hours to 2 days to install a new battery depending on what exactly you find wrong and how long the \"balancer\" has to run.","human_ref_B":"Car batteries are large and heavy, so it's not as easy to swap them out. Also, since those batteries deliver *a lot* of power and get hot, most of them have an extensive cooling system. When you're removing a car's battery, you're not just disconnecting the terminals, you're also disconnecting a liquid cooling loop. It may need to be drained, dried, whatevered.","labels":1,"seconds_difference":6626.0,"score_ratio":2.0} +{"post_id":"pofw9x","domain":"explainlikeimfive_test","upvote_ratio":0.87,"history":"Explain like I'm five years old: Why do some plugs have obviously inefficient designs, e.g. cover multiple outlets, or only fit in the very last spot because they bend at a right angle downward?","c_root_id_A":"hcwm8c8","c_root_id_B":"hcwfm8y","created_at_utc_A":1631674944,"created_at_utc_B":1631671721,"score_A":5,"score_B":3,"human_ref_A":"I feel like this is directed toward in-home 120vAC wall outlets, which i feel has been adequately addressed by others. But if we're going for \"bent at a right angle downward\" plugs, might i present for your review the 3- (and 4-) prong outlets used for welding and other heavy-duty, 3-phase, high voltage (277vAC & 480vAC) outlets. These are designed with a bent segment in one of the plug tangs so as to act as a \"key\" so you don't accidentally plug it in incorrectly and blow the transformer on the equipment. 3-phase systems require a bare copper ground and 3 hot wires that are individually half of the total effective voltage, but when measured across 2 hot lines equal the total voltage. Confusing, right? Lol. That's because they are run slightly out of phase, so that alternating current (AC) can behave similarly to direct current (DC). AC has peaks and valleys and flows in both directions, but is also susceptible to demand fluctuations. DC is a constant supply, but only flows in one direction, but is unaffected by demand fluctuations. 3-phase combines both of these attributes by providing 3 individual lines of AC that are milliseconds apart (out of phase) so that each of their valleys are covered up by the peak of the next phase, essentially turning AC into a constant line of peaks with no valleys (aka: DC), but able to flow in both directions with no risk from fluctuations. Hopefully this left you with more questions than answers. Lol.","human_ref_B":"Part of it depends on the type of power the device needs.
