They have continued to elect people who promise them they won't have to make the necessary painful cuts. But now the EU and IMF may make that decision for them...\n\nNations like the US can continue to spend money when we can't afford it because world lenders believe they will eventually be paid back with interest.

They had to borrow more money. As a result the interest rate went up.\n\nGreece had difficulties dealing with those higher interest, but had no choice but to keep borrowing in order to pay the previous loans. But since Greece had difficulties, nobody wanted to lend money to Greece and the interest for Greece got out of control. \n\nAt the same time, other countries feared that the debt crisis would spread. If a country like Greece can't pay its debt, people would hesitate to lend money to other countries with weak economy, increasing the interest rate for others. If the interest rate goes up, it cost tons of money to the other countries. \n\nThis is why other countries, especially european ones, don't want Greece to bankrupt. It order to avoid that they lent money to Greece that was no longer able to borrow on the public market. \n\nHowever, when lending to greece they forced Greece to cut down its spending. This was supposed to ensure Greece could pay back. \n\nSadly this was a huge mistake (as admitted by Strass-Kann who was director of IMF). By forcing Greece to cut down its spendings, it shrank Greece economy and increased unemployement. This mean, Greece income dropped just as much as its spendings, Greece was not any closer to be able to pay its debt and the situation got worse. \n\n***\n\nOne of the problem of Greece is that it doesn't have its own currency. \n\nIn general, strong economies should have a stronger currency in order to balance import/export. If a weak economy has a strong currency, it isn't competitive and it has trouble exporting. \n\nThis obviously can be a problem when countries with a strong economy like Germany share the same currency as a country with a weak economy like Greece. Germany gets a currency weaker than it should have, and Greece gets a currency stronger that it should have. Germany becomes very competitive, and Greece not competitive at all. Germany is effectively taking the jobs from Greece.\n\nTo become competitive again, Greece needs to devaluate its currency but it can't as long as it is using euro. \n\n", "What happens if Greece ends up voting \"no\" on the July 5th referendum?", "This is my understanding of it: The Greek government had been cooking its books for years before joining the Eurozone, the monetary union in the EU. The EU requires [certain attributes of an economy](_URL_1_) before a country is allowed to join this union. Greece probably did not meet these requirements but that was not apparent until [later audits](_URL_2_).\n\n\nIt was kind of too late to just kick Greece out of the union once everyone in the EU realized the Greece economy was a lemon. This situation would have been manageable if the entire world economy didn't crash in 2008. Because Greece was already in massive debt, and since they were in a monetary union in which they did not control the currency, Greece was put into a very bad spot without the tools to ease the crisis. Unlike Greece, in the US the Federal Reserve could manipulate the dollar in ways that would reduce the impact of the crisis. A lack of monetary tools was supposed to encourage fiscally responsible policy in the EU, but it ended up contributing to this perfect storm of economic crisis in Greece. \n\nThe EU had an interest in not allowing the Greece economy to crash, so a coalition led by Germany approved several [bailout](_URL_0_) [packages](_URL_3_) with the understanding that Greece would implement severe austerity policies (cutting social programs and spending) in order to be able to pay them back. The Greek people were not a fan of these measures, so they voted out the politicians that had made this deal. The new politicians were much more leftist and basically refused to pay the debts, getting rid of any austerity measures. \n\nNow to today, Greece needs another bailout to avoid default, but its creditors (i.e. Germany) are refusing to give them any money because they haven't paid off the last two bailouts. If Greece defaults on its debts, it will likely be removed from the Eurozone. Hence you see people running to ATMs withdrawing all their money before the Banks in Greece crash. Also contributing to this crappy situation are Greek politicians that are playing chicken with payment and negotiation deadlines. Through all of this, the Greek people are likely to emerge significantly worse for wear. \n\nEDIT: Read /u/green_velvet 's comment for clarification on austerity", "This comment is very related and a great ELI5 answer: \n_URL_0_", "This is more about the solution, or whatever comes next:\n\na, What happens if Greece accepts these terms? They get the money, pay back the IMF. But there is a huge ECB payment coming up next month. I have the feeling, just as most of the people that this can't go on.\n\nb, Most importantly, what happens if they refuse? The immediate thing would be that they default on the IMF loan. What happens after that in detail. What will the EU do, what happens to the peoples money.\n\nc, And connected to that, the default. They wouldn't default on everything, but what does a real government default means. I get that people are talking about that here as a huge deal but all I see is the IMF and the ECB loans and defaulting on them. Or these are enough to bring that devastating effect.\n\nd, And then there's the actual money. If they default, what happens to it. All those euros in Greece, owned by the people. Why would it destroy peoples lives. The government said it will pay the wages and the pensions. What happens to it if they leave the zone?\n\ne, And the last, grexit. Why is it so unavoidable and necessary? Some people talked about the devaluation of the money (which is obviously niot possible with the euro) and that would help the economy. Some said this would again, destroy the average citizens life? I understand some of the upsides but not all.\n\nI got some of it, but there is not a single full picture about these things. I hope someone will be able to answer at least a few of these questions.", "As a german I heard, that we gave them a lot of money and I really dont get why they hate us so much.

Hopefully someone can present a truly balanced ELI5.", "Why would Greece's exist from the EU affect american markets?\n\n_URL_0_ ", "Rarely will you see an explanation of Greek debt that mentions how huge hedge funds basically ran the show. This is a [fun place to start](_URL_0_):\n \n > Just look at how banks like Chase behaved in Greece, for example.\n\n > Having seen how well interest-rate swaps worked for Jefferson County, Alabama, Chase “helped” countries like Greece and Italy mask their debt problems for years by selling a similar series of swaps to those governments. The bank then turned around and worked with banks like Goldman, Sachs (who were also major purveyors of those swap deals) to create a thing called the iTraxx SovX Western Europe index, which allowed investors to bet against Greek debt.\n \n > In other words, banks like Chase and Goldman knowingly larded up the nation of Greece with a crippling future debt burden, then turned around and helped the world bet against Greek debt.\n \n > Does a citizen of Greece do that deal? Forget that: does a human being do that deal?\n \n > Operations like the Greek swap/short index maneuver were easy money for banks like Goldman and Chase – hell, it’s a no-lose play, like cutting a car’s brake lines and then betting on the driver to crash – but they helped create the monstrous European debt problem that this very minute is threatening to send the entire world economy into collapse, which would result in who knows what horrors. At minimum, millions might lose their jobs and benefits and homes. Millions more will be ruined financially.\n \n > But why should Chase and Goldman care what happens to those people? Do they have any skin in that game?\n \n > Of course not. We’re talking about banks that not only didn’t warn the citizens of Greece about their future debt disaster, they actively traded on that information, to make money for themselves.\n \n > People like Dimon, and Schwarzman, and John Paulson, and all of the rest of them who think the “imbeciles” on the streets are simply full of reasonless class anger, they don’t get it. Nobody hates them for being successful. And not that this needs repeating, but nobody even minds that they are rich.\n \n > What makes people furious is that they have stopped being citizens.\n \n\n", "The responses so far have all been woefully wrong. The cause of crisis in Greece was like the cause of the crisis in the United States, Ireland, and Iceland. It doesn't have to do with a budget crisis but with a failure of banks during the financial crisis of 2008. \n\nDuring the financial crisis of 2008, the Greek government, like the Irish government and unlike the Icelandic government, borrowed other European countries' money to bail out failing Greek banks. The government was forced to bail out these banks because foreign European banks were heavily invested in the Greek banks and they risked failures, ie contagion, in their homes countries if the Greek banks failed. So Greece borrowed this money to prop up their banking system and in turn the banking system of Europe. \n\nThe terms that Greece negotiated for this money have been too onerous for the weak Greek economy, which unlike Ireland, has failed to rebound making continued austerity for the sake of paying these debts unlivable and politically impossible.\n\nRead this article. It's explains it succinctly\n\n_URL_0_. ", "Why can't the debt just be dropped? Why can't the Troika just say \"Do you know what? Forget the last £1.5bn, just forget it. We'll start again.\"?", "France and Germany wanted to sell lots of military hardware to Greece and a previous administration was happy to take their loans to expand their military. When the German and French banks failed because they made bad investments (like lending money to Greece to build up a huge military), the govs paid off the banks and took on the debt. In the past, the bank would have to cover their bad investments. With banks controlling most politicians, that was no longer an option. Our tax dollars paid off their bad investments and allowed them to continue playing the same game. Privatize profits and have govs and tax payers pick up their losses. What a game, what a scam.", "I'll try to provide an ELI5 from my point of view (Greek citizen). (Sorry for its length.)\n\nCurrent global economic system is based on borrowing money and paying the interests of that loan. You have a big problem when you owe a lot of money compared to the money you produce each yer(GDP =Gross domestic product). Due to wrong decisions, corruption in governments (they increased the size of the public sector so they can gain votes, huge projects were assigned to companies cause politicians were bribed (e.g. Siemens got many huge programs in Greece that way)), and tax evasion Greece failed to meet the growth of it's debt. (Many have already stated out that the true economic figures were falsified in order to join the Eurozone with the help of banks such as Goldman Sachs.That's true.)\n\nIn 2009 Greek Prime minister [G.A.Papandreou](_URL_10_) made an agreement with the [IMF](_URL_3_), so IMF would lend Greece money with low interest and Greece in return should reform some aspects of its economy to reduce the amount of money spent (austerity measures). Going under the IMF caused uncertainty in Greece and many retrieved their money from Greek banks leading to liquidity problems (not enough cash) which caused a need for a new loan to support Greek banks (Greek banks couldn't borrow directly any money because certain statistical rating organizations made sure they were demoted and lost their credibility even if it was OBVIOUS Greek banks wasn't the cause of the Greek debt problem (unlike Irish debt which was cause mainly by their banks)). Austerity measures led to reduced spending but also caused a huge problem in Greek economy, so a second set of measures were forced in 2011 in order to further reduce spending. Second set of measure reduced spending (cut down pensions, wages, etc) but also drove Greek economy to the ground (highest unemployment recorded in Greece, highest rate of people near poverty, reduced GDP ). It's easy to spot the black hole here, it's a vicious circle that proved their experiment with Greece failed. Now they proposed to Greece a third set of measures targeting pensions (which NEED to be reformed) and TOURISM in Greece (they want 23%VAT for restaurants and hotels) which would lead to huge reduction in tourists (Italy,Turkey,and Spain would benefit from that) and further shrink our economy.\n\nIt's clear that in order to get out of the vicious circle Greece must either boost it's economy (economic growth = higher GDP = more money \"produced\" per year) or have it's debt defaulted (you don't owe money any more because you are \"forgiven\")(partially or totally, like Germany had twice in 20th century).\n\n**END OF ELI5.**\n\n*(Bonus content/1st day free dlc)*\n\nNow some interesting facts:\n\n1. In the years 2005-2010 Greek economy problem was well known in Europe , but banks kept on lending Greece money so they can make profit.\n\n\n2. In 2010 G.A.Papandreou asked for a referendum with the question \"Do you want to join the IMF\", European leaders were paralyzed and counter offered loans without interest for some years and promised for future help (so he recalled it). If Greece refused to go under the IMF or demanded a haircut or even declared bankruptcy back then the only sure outcome was that European and American banks would collapse because they were holding a huge amount of the Greek debt (Later, European Central Bank bought that debt in lower value). Keep in mind that it was right after the collapse of [Lehman brothers](_URL_0_). [Deutsche Bank](_URL_7_) , [Credit Agricole](_URL_4_) would be the first banks that would collapse.\n\n\n3. It's [IRONY](_URL_8_) when German government accuse us of corruption when they REFUSE to extradite the number of suspect [Michael Christoforakos] (_URL_1_) (sorry i couldn't find an article in English) for the biggest scandal in recent Greek history (Siemens (German company bribing Greek government)).\n\n4. Tax evasion is a practice well known around the world ([yeap, even to Germany](_URL_9_)), is it a mere coincidence that most of the [tax havens](_URL_13_) belong to the [United Kingdom](_URL_2_)?\n\n5. Germany is the only country in EU that [violated the commonly agreed inflation target of 2% per yea](_URL_12_)r (wages would increase by 2% more than your GDP).That was possible by decreasing the power of its labor unions and putting political pressure on wages.\n\n6. When Greece took a loan to save its banks (low liquidity = low on cash to give if asked) European Union , IMF etc made sure that loan was calculated in the countries public debt. YET, when Spain took a loan for EXACTLY the same reason , that loan wasn't added to the public debt.\n\n7. 27% decrease in GDP since the first set of austerity measures, it's the HIGHEST ever recorded for a country during peace. And they can't figure out why we don't want a third set....\n\n8. **(Conspiracy time)** [Portugal , Italy , Spain and even France](_URL_5_) have the same problem as Greece. Certain [\"parties\"](_URL_6_) love the fact that Greece might fail if its citizens don't accept the third set of austerity measures. And those \"parties\" will make sure to make an example out of Greece for the next to come. The show is coming to end for us , one way or the other but it's time for Europe to face the real problem now and stop having Greek problem in the spotlight.\n\n\nEDIT: My only fear is the possibility Greek government has an agenda of forcing the country in becoming a \"left\" nation without asking us.. (and damn i am kinda leftist myself)\n\n@don_one I don't have a problem with Greece being in the spotlight if it was the major problem, but Greece is only 2% of the EU economy , even if its debt is totally defaulted(forgiven) there would be almost no negative outcome , yet Spain, Italy, France are in the G8, i can [bear](_URL_11_)ly imagine what a possible bankruptcy or a reduction of their GDP by 27% would cause in the world economy.\n\n@LxSwiss GOLD ? < 3 Thx kind stranger . And a black/white world would be SO boring..\n\n@moneyjewjew Let me know if you have any more questions\n", "Essentially, the Greek economy has never been particularly strong, but coupled with high high levels of corruption in politicians and the richest refusing to essentially pay any taxes, the country wasn't in a particularly great state before the 2008 economic crash. \n\nPost Crash the economy tanked, and Greece was left with extremely high levels of unemployment (up to around 30%). Unfortunately this reduced tax revenues even further and Greece entered a spiral. In the past, governments would invest into economies to kick start the economy and create employment, but the EU, IMF & World Bank around this time decided Austerity (cutting of social spending and investment ) would produce a faster recovery. So in return for large loans, the stipulations were for vast levels of spending cuts. \n\n6 years later and the economy has yet to improve, and austerity has had the complete opposite effect of intended, increasing Greece's debt while having little effect on the economy. \n\nSince then the World Bank and IMF have produced reports saying that austerity has deemed to essentially failed, and have apologised to Greece stating that they never expected it to go so badly. \n\nThere has been a growing movement in Europe over the last 5 years for anti-austerity -the idea that you invest in your future rather than cut to get the debt down (see Post War Britain for one of the best examples of this). This culmulated in 2015 with the election of Syrzia, who stood on a left platform of anti-austerity in order to get the back on track. \n\n6 months later the EU has started getting pissed of with Greece for not cutting what politicians promised 7 years ago. Which has now culmulated in a situation where the Greeks have essentially been asked whether they want to stay in the EU (and commit to more austerity) or not. \n\nP.S. I haven't got a source for this, but I have also heard that Greece has one of the best structural economies in the developed world, and that under 100% employment ( and hence 100% of tax revenue), they would actually have one of the highest surpluses in the world. This would essentially make this an employment problem in Greece, rather than a selfish welfare benefit problem, which unfortunately much of the media seems to suggest. ", "Would now be a good time to get a bargain on a villa overlooking the Mediterranean?", "Here's another version to compare to the other top comments:\n\nGreece's economy got hit really hard by the recession, relatively speaking. A lot of their economy relied on tourism which pretty much came to a halt when all the tourists stopped traveling due to the recession. In response to these tough financial times, the ECB (which is just the European version of the US Federal Reserve) and other EU governing bodies decided to implement austerity measures. This just means that you reduce government debt, either by cutting spending, increasing your taxes, or both.\n\nIf you ever took Econ 101 (which is unlikely since you are 5), you know that during a recession, governments are supposed to implement expansionary policy (increase govt spending, cut taxes) in order for the economy to get firing on all cylinders again. If you're wondering why the EU implemented the exact opposite, well... Tough to say.\n\nAnywho. Greece impemented these austerity measures in a severe way. More so then any other EU nation because like others pointed out, they've been in financial turmoil for a while and in order to get more loans they needed to implement even more austerity as part of the terms.\n\nSo you end up with a downward spiral of more debt, more contractionary economic policy, and an eventual situation where debt is so high and the economy is so weak that a default occurs. If this default happens then the EU lenders will receive less money then if they had restructured current debt levels and allowed Greece to enact expansionary policy. This would be your win-win scenario but it means the EU would need to admit that austerity was the wrong path initially.\n\nInstead it seems pride goeth before the fall and the EU (led inexplicably by Germany and not the governing units of the EU) is poised to kick Greece out of the union. Greece's economy will suffer, lender nationa will receive less on their loans, and the future stability of the EU will be brought into question.\n\nLet me know if you have any questions or thoughts.\n\n", "Some great answers here as I didn't fully understand this situation before reading this thread. So I guess ELI5: Is the United States going to go through something like this eventually since it owes over $18 trillion in debt?", "ELI5: From reading the comments, what I understand is that the fault lies with Greece. If they were to refuse to repay the loans, would some country that has loaned Greece a significant amount of money start a war against them to seize Greece assets? What ways are there for the countries that loaned them money to get it back?", "This story begins with the general economic crisis reaching Europe in 2008-10. A lot of European economic institutions and banks are in danger and so it is decided that Greece will take loans from them to keep confidence in the banking system high.\n\nNow, Greece is a unique country, economically speaking. It never went through an industrial revolution, so it has no industrial infrastructure. There is also a big tax collecting problem, as a lot of the big money-makers are shippers who have the ability to move their money overseas so as to avoid taxes. (There are more reasons Greece was unable to pay back the debt - of which genetic tendency to corruption is obviously not one of - but these are arguably the main ones).\n\nThis led to a problem of paying back the debt. This is where the EU, ECB (European Central Bank) and IMF (American/International economic organization) come in and force austerity measures on Greece - in other words: really harsh measures that kill its economy in order to raise money (the fact that austerity kills the economy is no longer debated, not even by the EU, ECB and IMF).\n\nThe Greek people have a problem with that, so they vote off the EU-friendly government that pretty much accepted all this and voted for the leftist SYRIZA party, which is against austerity.\n\nWhat is currently going on is SYRIZA fighting for lighter measures and the EU, ECB and IMF being unable to back down due to political reasons.\n\nWhat happens next is up to anyone's guess.\n\n(This is all based on [this non-ELI5 post](_URL_0_))", "**So what exactly is the problem?**\nBasically, Greece was hit hard by the financial crisis, and since then it has borrowed a lot of money that it says it can't pay back – at least not yet.\n\nAccording to calculations by Reuters, it owes its official lenders 242.8 billion euros, with Germany its biggest creditor.\n\nThe lenders include the IMF (International Monetary Fund), the ECB (European Central Bank) and the Euro zone governments.\n\nMany of the loans don't mature for years, even decades.\n\nHowever some do. In particular, Greece was due to pay 1.6 billion euros to the IMF by the end of June in overdue interest. After that, 3.5 billion is due to the ECB on July 20, and another 3.2 billion in August.\n\nOn top of that, more than 8 billion euros in short-term bills are due over the next two months.\n\nGreece says it has scraped together all the money it can to pay its debts – it even called in cash reserves from councils, hospitals and other public bodies. It says that, to pay the money owed, it would have had to stop paying money into pensions and public wages – which it refuses to do.\n\n**What happens if Greece doesn't get the rescue money?**\nBarring further surprises, it will default on at least some of its debts.\n\nSovereign default does have precedents, but it always comes with major economic upheaval.\n\nThough the consequences of that are long-term (difficulty finding lenders willing to invest in the country), there will be immediate side-effects.\n\nAfter months of massive withdrawals, fearing this very crisis, Greece's banks are surviving on emergency credit from the European Central Bank. Without that, they have had to impose capital controls to stop any more money going out.\n\nGreek people will have less money they are able to spend. Business will be unable to invest. The economy will head into recession.\n\nSo far the Greek government has refused to countenance 'Grexit'. However if no new rescue deal is negotiated, Greece would have to supply the banks with money itself, or they will collapse.\n\nBut the government has no money. The only obvious solution is to start printing new money to get cash back into the economy.\n\nThis 'new drachma' would effectively mean Greece has left the euro – at least temporarily.\n\nThe 'new drachma', even if it began on parity with the euro, would quickly lose up to half its value. Essentially, the value of everything in the country would be halved.\n\nThere will be high inflation, and the new exchange rate would make imports much more expensive. Life will get even harder for ordinary Greeks and Greek businesses.\n\nOn the other hand, some economists say it would stimulate the local economy and, in the long run, leave the country stronger. There is fierce disagreement over this view.\n\n**Why would the Greek people possibly want this?**\nThey are sick of austerity. Unemployment has sky-rocketed, wages halved, pensions were slashed, public bodies like hospitals, schools and universities starved of funds.\n\nMany no longer believe that austerity is just a necessary, temporary measure to put the country back on its feet. They believe it is wrecking their economy and their lives. They are willing to take a risk and try something else.\n\n**How will all this affect other countries?**\nThe euro is already tumbling on international markets.\n\nIf Greece defaults it leaves many of its neighbours short. Germany is owed 57 billion euros, France 43 billion, Italy 38 billion and Spain 25 billion – on top of those countries' contributions to the IMF loans.\n\nThe loans don't mature for almost 30 years, there is almost no interest on them and some of the loans came with a 10-year moratorium on interest payments, so it's not like the countries need the money back immediately. However it's still a lot to have to take off the bottom line.\n\nConfidence in Europe, and the euro, has been profoundly shaken. Eyes will turn to the continent's other weak economies such as Portugal, Spain and Italy. They may start to lose capital and investment.\n\n**Is it just an economic problem?**\nNo.\n\nThis could also drastically change the political balance in Europe. If Syriza makes a success out of splitting Greece away from the rest of the continent, it will embolden other nationalistic parties such as the National Front in France or UKIP in the UK.\n\nFuture elections in Europe could see a surge in nationalism, a rejection of the European project, potentially enough to threaten Europe's stability as a political union.\n\nSpeaking of which, the UK is in the early stages of debate on a referendum on whether to stay in Europe, next year. If Europe is a basket case this time next year, public opinion (currently in favour of staying in) may drastically change.\n\nThen there is the question of Russia. Syriza has already made overtures to the Kremlin, with Tsipras a star speaker at Putin's recent big international summit in St Petersburg.\n\nIf Russia comes to Greece's aid, with money, other support (or both), it will be a new factor in the current Cold War-like tensions between east and west.\n\nGreece has already expressed its anger at Europe and NATO for not doing enough in its regular chest-bumping with Turkey. If Russian warships find a friendly berth in Greek ports, the strategic map of Europe is drastically redrawn.", "What I find particularly disturbing about this whole mess is that in the early 2000s, when Greece joined the Eurozone, almost nobody in Brussels expressed concerns over how much of Greece's economic boom was built on borrowed money. The same troijka institutions demanding Greece to reform and slash spending helped in allowing this mess to happen. Goldman Sachs didn't mind lending the Greek government lots of money when they wanted to invest in prestigious projects like the 2004 Olympics. Complain about the Tsipras administration all you want, but you can hardly blame the Greek people for looking toward an alternative to the traditional New Democracy and PASOK governments.They led Greece to spend too much borrowed money in the first place. These same parties and institutions complaining that Syriza doesn't do enough are fucking hypocrites.", "This comment board is a pretty good example for the two camps that people have been forced into through the media's bizarre simplistic and ultimately corrupt portrayal of how the global capitalist system works. \n\nThe main thing the Greek crisis is pointing out is that the world's entire economic system is resting on a house of cards made up of debts that can never be paid (and this includes the US economy/banks, and the supposedly responsible German banking system) The EU itself as a economic system that forces drastically different countries to use the same currency and fiscal systems was never a good idea. Basically the statement that the Greek government is irresponsible and is spending more than it makes is true, but it is only true because of the following:\n\n1) Goldman Sachs directly helped them hide their bad finances in order to join the EU and start taking out giant loans\n2) German banks knew exactly how risky loans to Greece were and plowed in because they were under the crazy assumption that the EU/IMF would never let basic math come home to roost. 3) There is no way for Greece to pay back the debts that German banks and the EU signed off for them to accumulate. The banking system always knew this and expected to start seizing Greek assets as soon as they stopped paying. This is essentially the same model as a loan shark...sure you can blame the idiot for taking a loan out, but you then also have to point out the loan shark nature of IMF/EU making loans they knew were mathematically impossible to pay off.\n4) The financial world is quaking at this situation because it exposes all the fake/bad math that exists built into our economies. If you acknowledge it in Greece then you also have to acknowledge the very same situations in Portugal, Italy, Mexico..the list goes on and on.\n5) They let Greece go this far with extending promises they knew they couldn't meet because the alternatives of admitting that all their math is off is terrifying. There are many banks that would be insolvent immediately if they have to admit all the bad loans they've made to countries just like Greece. \n\nGet ready for a rough ride world, Greece is the canary in the coal mine. \n\n", "Could we PLEASE have the top comments sourced?

It's like someone being on food stamps and buying a Ferrari. \n\nI don't blame the Germans and other euro zone members for refusing to bail out Greece *again* while they fail to address the fundamental flaws in their economy. Why should they subsidize and bear the burden of Greece's irresponsibility? There are going to be some very hard times ahead until a strong leader tells them that they're going to have to do some very unpleasant things and everyone is going to have to sacrifice. Blame only gets you so far, and while the rich certainly need to contribute, it won't solve the problem.\nEdit: mobile formatting", "If the Economy of Greece does collapse, what would that mean for the rest of the world?", "*I'm a bit late to this. Hope this doesn't get buried!*\n\nFor those who are interested in a little bit of a longer read (and obviously not ELI5 - but by no means technical), get the book Boomerang by Michael Lewis. It covers the financial crisis as a whole but also thoroughly explains what exactly went wrong in Greece with a few absolutely mind-blowing examples. \n\nAnyway, here goes a shot at explaining the whole situation, from joining the EU to what's going on right now. \n\nBefore Greece joined the Euro, the EMU (European Monetary Union) had set a number of requirements a country had to meet before they'd be allowed to join the Euro; this to make sure that only financially stable countries could join. Amongst them the maximum 3% budget deficit, but also things like unemployment rate. At that time (mid to late 90's) Greece didn't meet those requirements at all; they were struggling with a pretty serious unemployment rate and had a pretty sizeable budget deficit (meaning they spend more than they get in income), possibly even around the 10-15%. \n\nIn a few years seemingly they managed to have solved this, while in reality they did some 'creative bookkeeping'. In essence, they simply didn't record a lot of expenses and put people on the governments' payroll just to make it all seem well. In reality though, those people got a large sum of money monthly for pretty much doing nothing. The EU frankly failed to notice how Greece went from pretty much being a third-world country in a lot of regards to a financially healthy country like they pretended to be and let this all happen.\n\nTo quickly clarify the 'third-world' part, Greece never was a rich country (always had the lowest GDP per capita of the founding Euro countries) and when you look at things like tax morality or corruption, they score not just as worst in Europe, but also used to rank amongst the worst in the world. When I researched this in 2012, the country was ranked just as bad as China on the Corruption Perception Index ([you can find the data here](_URL_0_)). Not only that, a huge part of their economy depends on tourism and besides that not much else, which also made it a lot harder to compete with the rest of the Euro zone.\n\nNow as Greece managed to join the Euro, a couple of things changed. One of the things was that they could borrow at much lower rates; the rates of the most credit-worthy country in the Euro zone being Germany (I think the interest rates went from somewhere in the 10 to 5%. Now instead of taking responsibility and fixing the financial issues, the Greek leaders saw it as (if I may quote Michael Lewis) \"a stuffed piñata full of free money\". They started ambitious projects which would never logically have any meaningful return on investment which only caused the bubble to grow. At this point (we're talking 2001-2007 here), the Greek were living first world's standards on borrowed money. \n\nOnce the financial crisis started in 2007 and especially once the Euro-crisis (which is a separate part from the banking/housing crisis which started in the United States) started later towards 2010, the world found out what really had been going on in Greece and the bubble bust. It wasn't just a crisis like it was in other western countries, there were fundamental issues underlying the Greek system which means the solution isn't as simply as in other countries (as Europe is slowly but surely climbing out of the crisis as we speak). This meant serious reforms had to be done which takes a lot of political responsibility from the leaders at that time. I'll explain what happened further down this post. \n\nWhy? Well, imagine yourself as a small child getting a candy bar from your parents. Now imagine yourself as your parents take away that same candy bar. How does that make you feel? Pretty bad I reckon. Most people who get this question would actually feel worse than if they hadn't gotten that candy bar in the first place, which is a very important psychological phenomenon (explained by Daniel Kahneman, go read his book \"Thinking, Fast And Slow\" if this interests you). This exact same thing happened to Greece, they enjoyed the feeling of having all those privileges and right now have them stripped away from them, one by one. \n\nThe problem is, these reforms are mandatory. In Greece, you could be eligible for retirement in your mid 50's (compared to 65 in most other European countries) and now this just isn't financially possible any more. Another thing would be how there just wasn't an independent body that would control taxes and catch those not paying up. The list goes on with things that needed to be changed fundamentally but more importantly, will require a shift in mentality from most of the Greek people. This is simply something that does not come easily. \n\nNow another problem is, Greece was not rich to begin with, while they were still buying things at European prices. The effect of this is that a lot of 'common people' struggle to even make ends meet. People literally freeze to death during winters because they get cut from electricity/gas (you can look up the news for this). There's a humanitarian crisis going on but because the country is still in massive financial problems, there isn't much that can be done besides stopping the bleeding momentarily.\n\nAnyway, the politicians in the country didn't really want to admit that this was all their doing in front of the big public and lose their voters (and to be fair, it was mostly their predecessors' doing) so instead they blamed the European Union for things like putting them in an humiliating position or for any cuts in general. If you listen to current PM Tsipras' speeches you will see this exact thing; shoving pretty much all the blame for the position the country is currently in towards the other countries. Right now there's a massive anti-European movement in Greece which just flat out refuses to comply with any mandatory reforms, which is what's causing the problems right now. \n\nJumping slightly back in time, with the elections of last year Syriza is now the party in power and they are the embodiment of the anti-European voices in the country. Tsipras has played the game hard trying to get Greece out of these reforms, but their creditors won't budge. *If you ask me, with reason. If Greece were to ever become a stable country within the Euro zone, they will still need to keep making reforms to make sure the tax morality and corruption is on-par with the rest of Europe. They also still need to fix numerous things like retirement age (which is where part of the debate right now is on about). If they don't, it's just waiting for something like this to happen again.* Tsipras made serious promises during the election period saying he'd end all the cuts, but it puts him in a very difficult position because he has to come to an agreement with the creditors. Now both sides are on an impasse, and Tsipras appears that he doesn't want to take responsibility for either a grexit (Greece+Exit) which can cause serious instability for years or for another round of cuts which would lose him all the trust people had in him. Therefore he is giving the voice to the people, which may just as well be 'the death of him'.\n\nThe problem with the referendum is that it isn't on neutral terms. The question given will be \"Do you accept the reforms/cuts?\" which doesn't tell the whole story. If Greece were to vote no, it's pretty much over and out for them and the Euro - which is the part Tsipras doesn't tell. Instead, he publicly condemns the reforms and recommends all the voters to vote \"no\" in the referendum. That's also why the head of the Eurogroup, Dutch minister of finance Jeroen Dijsselbloem said that even if Greece would vote \"yes\", they strongly doubt the ability of the Syriza-led government to actually carry out those reforms. \n\nRight now, the situation is unclear. There is a payment due to the IMF tomorrow but if they cannot pay, there's still another month for them to try and pay those debts off before they default. It's pretty much waiting for what the referendum will bring and if Tsipras is willing to carry out the will of the people if they vote \"yes\" or if he might possibly resign as PM. Right now, it seems unlikely that the Eurogroup will want to negotiate with him again, especially on his terms. The Greek people will have the vote; which poison will they pick? Find out next week!\n\n**TLDR: The Greek fooled the EU, lived on high standards with borrowed money, once the bubble bust got privileges like pensions cut over the past years which seriously hurt the population and together with politicians not taking their responsibility caused an anti-European mood. Right now we're at an impasse waiting for what the referendum brings and the reactions from Syriza and the EU.**\n\n\n", " > There are people who are willing to do anything to stop any competition.\n\n[More quotes](_URL_0_)", "Is greece really loving opulent lifestyle with their high pensions and social programs?

I currently live in U.S. so I get to watch different news outlets and hear different perspectives. \n\nThe Greeks have a different culture and understanding of the world then most people. They are very social people and have a strong appreciation for family. Family and religion(at least for some part) for most Greeks means a lot. \n\nThere was a big instability caused by mainly the involvement of U.S. during cold war in the 1960s. There has been documents and proof that the U.S. government assisted in the establishment of a military dictatorship in Greece. (_URL_0_) \n\nI would pinpoint this dictatorship as the start of the crisis but also the start of the modernization of Greece. There have been extreme loans taken on the name of Greece that are still being paid off. These loans were partially used to build roads, schools and modernize Greece. However the big majority of the loans were used to hire public servants. \n\nThis period of time created the public servant culture. According to law it is illegal for the government to fire a public servant unless he has been involved into criminal activity. That means that working as a public servant is a very stable job. It is a dream job for most people. Hence the public sector exploded in size over the past few years. \n\nIt was often used by politicians to attract votes by promising positions in the public sector. But as you would expect hiring people that you can't fire to do nothing can be sometimes a problem. For the most part the public sector is very strong and stable but there is bad organization for it that in some cases there is surplus of workers in one place and lack of workers in another. \n\nGreece is a very socialist country regardless of who is being elected to lead. Regardless of social position the values of socialism are widely accepted. The idea of giving from one's surplus or wage to help the poor, seniors, handicapped have free education, free healthcare is viewed upon strongly. There is a strong sense of empathy between Greeks, and I haven't met a person from Greece that would disagree with the value of free education, healthcare etc. \n\nThe main income of Greece is from tourism. Farming used to be a big sector that has been slowly dying. \n\nA President of Greece (namely _URL_1_) with his party, have faked data to join the European Union because they saw a benefit from the common currency and boost in tourism. \n\nEuropean Union since then with different imposed rules have been slowly killing the economy of Greece by weakening other sectors of the economy. Farming has been slowly dying because according the European Union Greece is allowed to export a specific amount of tomatoes, peaches etc etc. As a result the surplus would often be bought by European Union for almost nothing and be left to rot and thrown away. This created a productivity slowdown. Moreover the European Union, would often pay farmers to plant Acacia in their farms as part of an ecological movement. Acacia is a very weird tree that has very long and deep roots and often destroys the area where it is planted because it is very expensive to remove. As a result big fields that used to yield lot of fruits etc are now useless. The farmers that were short-sighted got a big amount of money that ended up wasting around and left without a job. Farming was more or less destroyed by the rules of European Union and Greece had to import food from nearby countries (Like Turkey). \n\nCorruption in Greece is big. Not as big as in many other countries but there is a lot of \"white-collar\" crime. Big companies from Canada and US pay off politicians to provide with public available land and resources with tax free zones that end up ruining the environment driving tourism away from some areas. \n\nThe Greeks are people that like to enjoy the today and often ignore the consequences of tomorrow. They can be very obnoxious and many of them would appear to be spoiled. There are always exceptions to the rules of course. \n\nAs a result of all of the above, the people leaving the country side and coming to big cities with increased poverty for better \"opportunities\".

Greece didn't have alot of blocks to begin with so they borrowed some from other countries. The other countries said that was fine as long as greece gave back the other blocks as fast as they could. Greece stacked the blocks on their tower but found that their tower was still small in comparison to the other countries.The other countries were worried that if Greece's tower fell over, it might knock theirs down so they made sure Greece could keep building on their tower by giving them more and more blocks. Greece was still no closer to having the biggest tower AND they still had to give the other countries some blocks back once they could afford to.\n \n Things are looking bad for Greece, they need to give back the blocks and find a way to make the tower gap smaller. Greece decided to get blocks from a different country to return to the first country.

And the German-dominated European Central Bank has given Europe a monetary policy that's about right for Germany, but so tight that it has thrust Greece into a depression.\n\n > So Greece is squeezed between a crushing debt burden — 177 percent of GDP, about twice the level in the United States — and a deep depression that makes it difficult to raise the money it needs to make its debt payments.\n\n > For the last five years, Greece has been negotiating with European Commission, the European Central Bank, and the International Monetary Fund (dubbed \"the Troika\") for financial assistance with its debt burden. Since 2010, the Troika has been providing Greece with loans in exchange for tax hikes and spending cuts.\n\n > Rich European nations such as Germany believe they're simply insisting that Greece live within its means. But the austere terms of the bailouts have caused resentment among Greeks and contributed to crisis-level unemployment and poverty. In January, they elected a new left-wing prime minister, Alexis Tsipras, who promised to reject the previous bailout deal and secure a more favorable agreement.\n\n > But he has very little leverage. In 2010, Greek debt was widely held by private banks, so a Greek default could trigger a financial panic. But since then, this debt has been consolidated in the hands of rich European governments, greatly reducing the risk of a financial crisis if Greece defaults.\n\n > So Greece faces a hard choice: it can accept the Troika's demands for further austerity. Or it can defy the Troika, which would likely lead to a default on Greek debt and possibly a Greek exit from the euro. The Greek government is holding a referendum on July 5 to let voters choose between these bad options.\n\n > In the meantime, the Greek economy is melting down. Knowing that Greek euro deposits could soon be transformed into devalued drachma deposits, Greek people have been rushing to ATMs to withdraw as much cash as they can. That has forced the Greek government to close the banks and limit withdrawals to €60 per day.\"", "[Here's a simple primer](_URL_0_) by a Chicago Booth economist that explains the crisis in Greece in a very elegant way. \n\nIt essentially walks you through everything that has happened over the last few years, and explains the crisis from different actors' angles.", "If there were no debt interest from the beginning, Would have Greece already been able to pay back their debt?

Fruits such as citrus, berries, and melons are nonclimacteric and best when picked as ripe as possible, because while they can soften and develop a smell, they won't get any riper (sweeter) when detached from the plant. **Climacteric** **fruit**, on the other hand, responds dramatically to the plant hormone *ethylene*. Once triggered by ethylene, ripening enzymes break down stored starch into sugar.

They also store sugars as starch, because its way more efficient than storing it as sugars (sugars we detect as sweet when we eat them, starches we don't, even though its the same material overall just in a different arrangement). Fruits still live for quite a while off the stem and enzymes, special proteins designed to make reactions happen faster, are still breaking down starch into sugar to make it sweeter and breaking down structural molecules to make them softer." ] }

why did nazi germany treat british/american pows half-decently, but russian/slavic pows horrendously?
I understand that the Nazis consider the slavic people to be subhuman rats and therefore had no morale issue with treating them so badly but why did they go to the bother of treating British/American POWs half-decently? Why not just put them in terrible concentration camps like they did with Soviet POWs? The only thing I can think of is, say if Nazi Germany were successful in conquering Britian, it would be difficult for them to explain to British citizens why they treat their POWs so badly, wereas for Russia and the east they planned to just "exterminate" them anyway.

For example, scientists noticed that if you heated food and then cooled it off and kept it well covered, it would prevent the food from spoiling. This supported their idea that the small organisms which were causing the food to go bad were being killed. \n\nLater on with the invention of ways of observing the tiny organisms (e.g. powerful microscopes,), we confirmed their existence and their role in disease. \n", "At its simplest, germ theory explains that there are microorganisms (Bacteria, viruses, fungi, etc.) and they are the causative agents of disease.

To explain the cause of sickness any number of hypotheses were generated including miasma theory, humorism, and witchcraft but failed to recognize the actual disease causing agent and often did little to mitigate the issue. Skeptics and critics of these ideologies had to overcome a great amount of resistance from scientist (and doctors) to finally recognize what we know today as germ theory.

He established four main tenants of diagnosis which are dubbed Koch's postulates:\n\n1. The microorganisms must exist in great number in an infected host, but be absent in a healthy host. \n2. The microorganism must be isolated from the sick host and grown in pure culture.\n3. The microorganism must cause disease when a healthy host is inoculated experimentally\n4. The microorganism must be reisolated from aforementioned experimentally inoculated host. \n\nAlthough there are certain exceptions to the above mentioned guidelines (which I can discuss if you want) these were the first parameters for determining the cause of disease and are the primary support for germ theory. \n" ] }

So some teams often have different racers going for the different objectives so they can get attention to their sponsors. However to perform well in a bicycle race you often need a team of helpers who make sure the main riders are well rested and comfortable.

It happens, don't get me wrong, but its far less common than you think, its far harder for them to get away with it, and its seldom as overtly evil as one might think.\n\nHowever... Every physical object is going to have tradeoffs. Would you like your remote control to weigh twenty pounds but never wear out or need batteries - or would you like it to weigh five ounces and wear out after 10 years of average use?\n\nCustomers have spoken and they want cheaper, lighter, fancier shit - and they are wiling to pay for it.\n\nSo really what companies do is design the product so that in average use conditions it lasts a reasonable period of time, and then give consumers a warranty that covers a shorter, but still reasonable, period of time. And then if your toaster, or television, or jeans wear out sooner they replace them with an apology, and if they last longer... good everyone is happy.\n\nThe real issue though...

why does the american education system (primarily elementary and middle school) insist on the "everyone wins" policy.
It seems counter-productive that teachers are told not to necessarily tell their students they are wrong. A teacher of mine said this is to prevent "hurting the feelings" of students?

Why do you think the education system \"insists\" everyone wins?\n\nMy wife works in schools all the time and teachers routinely tell students they're wrong when they're wrong.", "I'm not sure that teachers necessarily don't tell their students they are wrong, though I have had instances where teachers have let their kids down softly to escape helicopter parents from bursting through their class room door and yelling at them.\n\nLots of parents are very protective of their children and many think that little Susie can do no wrong.", "I've seen it, I've lived it. What you talk about happens. Not all the time, mind you, but my grade school teachers would have all sorts of little class competitions and \"team building\" exercises, and everyone would get an award or _something_.\n\nI blame white, middle class suburban mothers who are sissifying our children because they believe their _precious snowflakes_ are _special_ and deserve a fucking medal for everything. The can't accept that a diversity of people can demonstrate a diversity of strengths and talents, that their children aren't going to be good at everything, and they feel the impulse to smother their children with emotional over-protection.\n\nSo these Smothers have rallied and pressed our school systems into conforming to their bizarre sense of reality, and all children have to bear the consequence of it.\n\nAnd it is counter productive. Children who grow up with this are emotionally fragile snowflakes as adults. They expect a handout with everything, don't do things \"because it's hard\", and these fucked up mothers think their children are fully prepared to be adults the second they turn 18.\n\nI've seen this in my school system, but I wasn't treated this way at home. Several acquaintances I know did get this treatment at home, and as a result, one, for example is finishing his Masters and won't look for work in his field because he's \"afraid\". He can't handle the feeling of rejection should he not get the job, so he doesn't look in the first place. He'd rather work a part time job at a bookstore. Others just don't know how to act as adults and turn to binge drinking because their behavior is utterly unchecked; they only kept in line when their mothers were there to wipe their asses. My fiancee tutors, and some of these college kids, they skip class all year long and then attempt to guilt her, \"I'm going to fail this semester if you don't help me.\" Really, kid? Like not going to class and not taking notes has nothing to do with it? Do you think she actually believes your line of bullshit? Or that it's even necessary?", "I am a teacher and recent college graduate, and I have never been told not to tell a student they are wrong. We try to soften the blow a little, and the main reason is that constant negativity makes students feel worthless and helpless when we want to empower them to improve. \n\nWe are,trained to focus on positives and strengths rather than weaknesses. There are a few driving ideologies behind this. One is the concept of self efficacy. Once a student starts to think that they are too dumb or incompetent to be successful, the chances of them closing the achievement gap hits close to zero. Children are very perceptive of this even at an early age. My first graders have already started to idenfity and point out the better readers, early finishers, and discussion dominators in the class. While students can't officially drop out until the age of 16, they give up in elementary school. By focusing on what students have accomplished, and giving praise alongside corrective feedback we help keep students from frustrating out.\n\nSecondly, pointing out what students lack does not help much with promoting student growth. If I make a list of things a child cannot do or does not know it does not tell me where to start instruction. I need information on the skills they do have so I know where to go from there. I have also noticed several mistakes made in the classroom our when students try to apply information incorrectly. They have a strategy that works for one type of problem but they get the wrong answer when they try to use it somewhere else. If you do not explain that, they may discard that strategy as worthless.\n\nThat first part addressed the never telling students they are wrong or need to improve misconception. The fact is we do, quite frequently in fact, but we aim to keep a ratio that favors praise over redirection.\n\nAs for the idea that schools have an everyone wins policy, I do not feel that my school buys into that. Some schools probably do, but I do not think they are the majority. In my classroom I make sure all students are praised, even my lowest students. The lowest students are the ones that often need it the most to keep up their self esteem. The big focus is on growth. If a student comes in not knowing their letters but end the year near grade level that calls for celebration more than a student who barely grew at all but is still exceeding becuase they were more than a year ahead coming in (although typically the gap in achievement grows each year). However there are special celebrations only available to students who meet a prescribed standard. Some of these celebrations are academic, but others are behavior oriented. The biggest celebration of each quarter is based on district test scores, and only the parents of students scoring above 80% (where a passing score can be as low as 60% becuase the of the way questions are tiered) are invited.\n\nIn addittion to only presenting awards to students who demonstrate academic excellence, we don't withold the fact that students are failing. Almost all of my students who were at risk of being held back were at the conference when I informed their parents and compared their score to the benchmark and went through a pile of failing assignments. We like to focus on what students have accomplished and what can be done to improve towards a target, but they need to know where they are. " ] }

In essence it simply isn't a good conductor and absorbs/dissipates that electricity as heat (which you can feel if you run too much through a wire). The reason we still use copper wire despite it not being a very good conductor is because while there's better materials they're too expensive, and copper is \"good enough\".", "Every electrical conductor has a certain resistance, that depends, amongst other factors, on its length (measured in Ohms/meter). In a longer wire, the electricity must travel through \"more resistance\", which will limit the electrical current, that can pass through. For example, if a wire with a given length has some electrical resistance, then a wire with twice that length will also have roughly twice the resistance, only allowing half the electrical current to pass. If you want to send a high current through a very long cable, then you will need a high voltage, to overcome the resistance of that wire. You can also use a wire with greater diameter to allow more current to get through, as resistance also depends on the \"thickness\" of the wire." ] }

Anonymous sources are permissible if other facts support the assertions.\n\nParticularity: If a story attributes a stance, or a goal, or a motive to a public figure, does it give specific examples of conduct consistent with stance?\n\nEver since I read this post I've looked for all three things in news articles and it makes it pretty easy to distinguish fake news (fabricated) from news that isn't fake (just because something doesn't confirm your world view doesn't mean it's fabricated).\n\nOf course, there's still the issue of bias. Bias (implicit or explicit) can still encourage authors to make the facts fit the conclusion and that's why it's really important to read things critically. Be on the look out for logical fallacies that are used (many times very successfully) to manipulate readers. Appeals to emotion, attack the messenger, straw men, and ad hominem attacks (i.e. personal attacks), are good examples of logical fallacies that unscrupulous (or unwitting) reporters use to force a particular world view.\n\n", "Well, here's how I do it...\n\nFirst thing is a \"gut check\". Does this news sound unlikely? Does it go against common sense? If it does, I head over to the front page. Is there a bunch of news on the front page that also sounds sensationalist, or is grossly skewed one way or the other? If so, I'm assuming this is BS and I'm outta there.\n\nSecond thing is are they the only one reporting it? News does not happen in a vacuum. If they're the only one reporting it and it's been a few hours, I call BS and move on.\n\nThird is the site itself. What kind of reputation does it have? Is it known as a serious news site, or a fringe site? I'm going to give a lot more credence to the NYT, NPR, BBC, AP and Routers than to the Huffington Post, Breitbart, Fox, or the Other98.\n\nLastly is, does the reporter cite sources? Obviously some sources are anonymous, and that's fine, but if they quote statistics or studies and don't reference those, I get suspicious. If the phrase \"some people say\" (or anything similar) appears anywhere in the article, I'm assuming BS." ] }

So the major issue was the separation from the mother. \n\n\nEdited to add, because I was curious: another potential reason for the herd to reject a baby without a mother is this, written about cows who are herd animals like bison are: [\"It is not by accident that a cow rejects the approaches and nursing attempts from all calves except her own. If females let all the calves in the herd nurse, then only the oldest calves would survive.

{ "a_id": [ "djv0h72" ], "score": [ 4 ], "text": [ "First of all, personality testing in general is not that accurate. The problem is that often there are flaws in the questions such as questions that don't measure what they intend to measure, issues with culture or preexisting knowledge and problems with the wording of the questions.\n\nThe most obvious \"flaw\" in these kinds of tests can be seen if you take it more than once. In general personality is something that should remain consistent over time, changing very slowly if at all. But people will sometimes answer those questions differently depending on their mood or recent experiences and that can cause significant changes in the results. For example, last weekend I went out with friends and had the most amazing time, everything lined up just right where it was a REALLY fun party. So my brain will tend to rank \"going out\" as more fun and I'll appear more extroverted. Wheres if I had a really shitty experience last weekend, everything went wrong, people got arrested and someone broke my nose. I'm less likely to rank going out as fun and therefore will appear more introverted. \n\nBut in theory each question is placed there to measure a particular indicator. There are normally many questions that measure that indicator and after all are answered they can be used to measure consistency and dominance of that indicator. For example, you might ask 5 different questions that involve \"going out\" vs \"staying in\" to see what people prefer and that might give you an indicator if they are introverted or extroverted.\n\nIf the questions in the test were organized by indicator it would be obvious to the test taker what was being measured. One of the secrets to these tests is that they measure many indicators and mix up the questions. So the introverted questions might be number 1, 7, 16 and 30. So they seem unrelated but in reality they are not. " ] }

When living in any big city or even small town, inevitably we are subjecting our bodies to the relentless streaming of wireless information passing through our bodies.

why can i eat a lot of hot pizza, but only a little cold pizza?
So I've noticed that when I get a pizza at night, I can eat around 5-6 slices, as it's fresh out tha kitchen. But if I eat that same pizza for dinner the next day, when it's been sitting in my refrigerator, I can only eat 2-3 slices before I'm full up. Is this something to do with liquid vs. solid cheese? Is it temperature? Am I crazy?

I hope ol' Darwin's take on the whole smiling thing is still interesting:\n\n Worked in a Fear and Emotions lab in college: Darwin tackled this one in OOS, and modern research bears this out. The \"Fear Face\" is an evolutionary response that maximizes survival in response to a threat (gasp gets some extra O2 in the lungs, lips parted mean you can get more when you need it, eyes wide open to let in more information about the environment, possible escape routes etc.). This instinctive survival tactic has become an innate part of the mammalian fear response. In social animals, seeing a fear response from another member of the species will activate a fear response in the observer. This is also a survival tactic; if you are looking toward me and you are scared, then I will know there is something to be afraid of and get biologically prepared to try and survive the threat.\nNow think about the shape of a \"Fear Face\" (jaw parted, lips turned down, eyes wide open, brow raised). It is the opposite of a smile (teeth together, lips turned up, eyes squinting, brow relaxed). So the smile evolved as a nonverbal method for communicating the opposite of fear (perhaps more properly- the total lack of fear) to other group members. Similar patterns exist in other social mammals (rats, dogs, meerkats, apes), but smiling is the human one.\nFurther reading: _URL_1_\n_URL_0_\nAdolphs, R., Gosselin, F., Buchanan, T.

It's unstable, can suffer from peak voltages/harmonics, and is filtered out anyway, when providing power to any digital circuit. (as digital circuits all operate on direct current, not alternating current)\n\nEverything that needs an accurate frequency (be it an antique clock, or your laptop), has an oscillator inside. In the antique clock this is a pendulum, in your laptop and almost all digital systems, a 'crystal'.\n\nIt works much like a tuning fork, which means that, when a voltage is applied, it will oscillate at a certain (very high) determined frequency, but always the same one (as long as the crystal doesn't get worn out/damaged.)\n\nThink of the crystal as a pendulum that oscillates not once but 1 million times a second. (called the frequency: 50MHz would mean 50 million times a second) Once you know this number of oscillations per second, you can easily make something that can count seconds. You just make a circuit that counts up to one million, and when that is reached, gives a signal that a second has passed and resets the counter.\n\nThere is also another (less accurate) way to generate a frequency, and it happens when you put a capacitor and an inductor (coil) - two electronic devices, the former acting to maintain voltage, the latter acting to maintain the same current - together in an 'resonant circuit'. It makes use of the fact that you put two energy storage devices together, and 'swap' energy constantly.\n\nImagine an iron ball hanging from a rubber band. As you pull the ball down, you store energy in the rubber band. You let loose, and the rubber band transfers it energy to the ball, which -once the rubber is fully flaccid- will have all this energy now stored as potential gravitational energy. Now gravity starts to pull the ball down again, storing that energy once again in the rubber band... Operating on a cycle. This cycle will have a certain frequency again, which you can determine by adjusting the stiffness/length of the elastic band and the weight of the ball. Once these variables are set, the frequency is set.\n\nHow can it get off sync? All electronic components degrade over time. This is called drift. Resistors, inductors, and capacitors suffer from it, but also crystals. Drift simply means that the actual value of the component will change, due to heat, corrosion, etc... Much like a rubber band won't stretch as well after 10 years of use.\n\nIf your microwave clock is fast, it probably means the oscillating digital circuit is faster than it was calculated to be, and it thinks a second is slightly shorter than it actually is. On a fun note, this technically means your microwave was 'overclocked' ;)" ] }

how do bbq restaurants work?
A few years ago I bought a Traeger smoking grill and I love to make my own BBQ. I know from experience that pork shoulders and briskets take at least 12 hours to cook, while ribs take 3-6 hours depending on whether you're cooking baby backs or spare ribs. All of this depends on what temperature you cook at (I prefer 225 myself). My question is how do they serve hot and fresh food? Most restaurants cook to order. Do they have someone cooking at least 12 hours in advance of the lunch hours? Then what about dinner service? Do they serve the same meat at dinner as they did at lunch? Is it possible that they would cook some meat until they're 90% done and finish it when an order is placed? Smoked chicken is great but leaves the skin unappetizing, unless you finish it with higher heat. How does a restaurant deal with that? When something like brisket is done, how do they keep it warm without drying it out? How do they plan for how much meat to cook? I realize that running out of something comes with the territory when your food is great. I have seen some shows that follow mom and pop shops around and that has answered some of my questions. I am more interested in larger restaurants or chains like Bandanas or Famous Dave's.

This is called par cooking.\n\nThey also cook stuff overnight.

Some just start super early and that's why many are only open for lunch... they may get in at 3am to smoke the meat, serve from 11-1 and that's end of day (like Franklin BBQ in Austin). Restaurants often have to hold food that takes long time to cook for service, and there are all sorts of warming boxes, etc. And BBQ joints do often run out of particular items due to the long cook time... they may make 10 shoulders or 8 briskets and when it's gone, it's gone for the day.", "Items like brisket and ribs can sit in warmers for long periods of time, where chicken can't. Often times the pit masters work awful hours putting their meat in the evening, and pulling it out in the early morning, then placing these hearty cuts of meat in warmers before moving onto other food that's harder to keep warm and delicious like chicken. As far as more local BBQ joints, once they're out, they're out. I can't speak for large chains, but I assume that they possibly keep already prepped food cold, and warm it up as needed.\nChicken - absolutely terrible, pain in the ass. I can't count the number of times we've tossed our entire whole chickens because the workers got tired of eating it, or no one bought it. You had to make several throughout the day because of picky eaters." ] }

whenever you break skin on a joint area, how come the healed/new skin comes in complete with wrinkles?
I just had my knuckle heal after a gnarly bit of road rash. It took about a month, but it's finally good. Having said that, the new skin came in with the same wrinkles from age (35 years old) that I had before. Shouldn't the new skin come in without any signs of aging? Or, does the body reproduce the skin in the exact same way it was before the injury?

Its not exactly hard to do if you have the right equipment and training, but not everyone knows how to do and IT can charge whatever they want for it.", "Data recovery software only works on data that is still (technically) on the physical disk.\n\nLet me explain:\n\nData on physical medium is stored as 1s and 0s, you may already know this. So there's different sectors filled with sequences of 1s and 0s. \n\nIn order to actually use storage medium, in computing we use file-systems to represent these sequences in different structures (files, folders, permissions etc.).\n\nFile-systems are plenty - from FAT, FAT32, NTFS, HFS+, FATX, ReFS, ext3, ext4, ReiserFS, ZFS etc.\n\nWindows uses NTFS by default these days. Apple's macOS uses HFS+, iPhones also use HFS+ (and since today they were swapped to APFS), Android uses a mixture of filesystems, but mostly ext4 for the important parts.\n\nAnyway, these filesystems decide how to store and access the sequences of 1s and 0s and how they are presented, and they are usually pretty documented.\n\nThey do this by having an area of the disk (or more areas) that is used to store a table that describes the physical location of the file contents.\n\nLet's say you have a file called Picture.JPG that is 1MB in size. Newer HDDs these days use a \"sector size\" of 4 KB. So Picture.JPG in this case it will use up 256 physical sectors on the disk. The filesystem stores the address of all these sectors in the table I mentioned earlier. So it will say something like: Picture.JPG is stored in sectors 100 to 200, then the rest of it is in sectors 5000 to 5156 (a file won't always be allocated continuously on the disk, but that's another matter: fragmentin and defragmenting a filesystem).\n\nWhen you delete a file, or otherwise destroy the data on a physical storage medium (be it hard disk, usb drive etc.), the 1s and 0s sequences that make up a file don't get removed from the disk, mostly because that's an expensive operation in terms of performance.\n\nInstead, the information about the file's location is REMOVED from the table of the filesystem I mentioned earlier.\n\nThis is also why usually it's very fast to delete 1 x 1GB file instead of 1000 x 1MB files. \n\nNow, because most file types have to respect some standard \"format\" in order to be valid, the data recovery software usually scans the whole physical disk for patterns of specific file/file types. For example, it can guess that a sector of the disk that has the contents of ````\" < FF > < D8 > JFIF\"```` is most likely a JPG file and then it looks for specific markers of the file format. This is the case of a lot of file formats, for example most PDF files start with ````\"%PDF\"``` etc.\n\nThe data recovery software also knows how a specific filesystem stores the data of file names and locations etc., so it looks for those patterns too.\n\nThis is rather an easy operation to do, AS LONG AS THE HARD DISK IS STILL FUNCTIONING and the DATA HAS NOT BEEN REWRITTEN.\n\nNow if you deleted File1.JPG, and somehow you wrote to the disk File2.jpg and File3.jpg, and because the closest available free disk space was where File1.JPG used to reside, then the contents of File2.jpg and File3.jpg will overwrite the data-structures that used to belong to File1.JPG.\n\nThis is why data recovery software tells you to not recover the data back to the same disk, so you don't overwrite the very own structures you are trying to recover.\n\nAgain, this is a rather easy operation to do, as long as the disk is perfectly functional and only the data from it has been made inaccessible because of a filesystem error or deletion.\n\nSpecialized data-recovery companies usually have very expensive hardware that can read the contents of a disk even if the disk is not recognized by your PC anymore. They can also recover broken PCBs, they can transplant the physical platters (the spinning thingies where your data is stored) to other HDDs in order to retrieve the data. This takes an incredible amount of time and a very clean room to do so. Even a speck of dust on the platter will make the data recovery very hard!\n\nA simple issue, from my own experience, can take a lot of time to fix if you haven't got this specialized hardware." ] }

Murder trials , for instance , are tried separately for each victum if they are heinious enough to try to ensure multiple life sentences , or were committed in several jurisdictions, also they prevent the inmate from being released for compassionate reasons or medical reasons since each conviction must be heard separately which then takes alot of time.\n\nEdit : Grammar mistakes" ] }

why muscle mass ≠ strength?
People with larger muscle mass lift less than people with smaller muscle mass at my gym, why? Steroids are not a factor. I know these people are clean. Edit: In both cases perfect form is used.

In conclusion finding out their real muscle to fat ratio.\n\nIn physiology you will find that strength of a muscle is a function of the cross sectional area only, which translates to basically, you NEED bigger muscles to gain more strength. No muscle no strength.\n\nThere can be several reasons why x guy(small) can lift more than y guy(big):\n\n* Their diet overall\n* Pre-workout meal\n* Their training method\nLet's say I'm training always on the limit of my capabilities. My brain will learn how to utilize 100% of the muscle mass available while let's say I'm training at 70% of my ability most of the time. My brain never really learns how to utilize 100% of the muscle, thus my record bench won't be as high compared to when I'd train 100%.\n* Attitude - lack of enthusiasm is a deal breaker when it comes bodybuilding.\n* Lack of sleep - another big no no when you want to gain muscle and achieve in the gym.\n\nIn a nutshell muscle mass = strength. Biggest proof I personally consider is when you first start training. After a month or so there are no noticable changes in your physique, but there are very large differences in your overall strength aka. you're not bigger, but you can move much heavier weights. This is also varying, if you're not giving it your all there might not be large gains in any area.", "If you're just watching people, you can't be sure what they're doing. Sometimes people work significantly below their maximum, for various reasons. De-loading, doing higher volume work, or another reason. Or the people you see doing higher weights could be using poor form and \"cheating\" somehow.\n", "Nobody's got it yet. \n\nThere's two kinds of weight training:\n\n- Sarcoplasmic Hypertrophy\n- Myofibrillar Hypertrophy\n\nSarcoplasmic involves a high number of sets and high number of reps and the intention is to increase muscle mass. This is usually done by increasing the size of existing muscle fibres via water deposits in the muscles, causing little increase in the actual number of muscle fibres (ie strength). So the person appears muscular, such as a bodybuilder, but is not necessarily as powerful as they could be for their mass. \n\nMyofibrillar involves low reps and a lower number of sets to increase the density of muscle fibres and trigger growth of new ones in a small space. There is little space 'wasted' due to water so in essence all muscular growth equals an increase in strength. This usually means those focusing on strength training do not gain mass as quickly as those focused on bodybuilding. However when you see a power lifter or Olympic lifter, you know that their size is due mainly to Myofibrillar Hypertrophy rather than Sarcoplasmic due to their impressive strength. \n\nThese two methods normally go hand in hand but you can focus your training on a particular aspect. For example, Bruce Lee heavily used Myofibrillar exercises, and was exceptionally strong but did not have a very large muscle mass. \n\nBasically if you put Ronnie Coleman in a wrestling match with an Olympic lifter of equal muscle mass, the Olympic lifter is gonna win.\n\nEdit: clarified", "Like you're 5;\nYou have two balloons: One is filled to be bigger but is filled with air. One is smaller but filled with water instead. Which one is going to have more impact when thrown?\nSome people work out to make their muscles bigger, some work out to make them more dense. ", "This is ELI5 people. I read 2 explanations and I have no clue what they mean. Maybe I'm just dumb but could someone please simplify it even more?\n\n[edit] thank you to Tankinator", "ELI5 version: All muscles work by pulling. Think of your muscle as a tug-of-war, with the people on the rope contributing to the 'power' of the muscle. Now you can have a lot of people on a rope and they'll probably be pretty powerful--this is like having a large muscle mass. However, you could also just have a small number of really strong people pulling the rope which also results in a powerful team. In one instance you're generating strength by adding more people (more muscle mass) and in another instance you're generating strength by making what people you do have stronger.", "Don't forget people, your form and CNS play a big factor in how much strength can be recruited from your muscles. Generating strength from your muscles isn't as simple as flipping a switch, and your muscles get to work. Muscles are made up of lots of muscle fibers, all of which need to fire in a certain sequence during the movement. As you lift, your brain is constantly learning the optimal pathways to recruit more and more strength from your muscles. Without the proper pathways, your muscles are just lumps of proteins.\n\nTL;DR: Muscle mass isn't everything.", "Okay, there's a ton of \"bro-science\" in this thread, so I'll chime in.\n\nThere are two main types of muscle tissue: fast twitch and slow twitch.\n\nFast twitch muscle fibers are much bigger than slow twitch muscle fibers, and are capable of moving a lot more weight than slow twitch muscle fibers, and are capable of doing it a lot faster than slow twitch muscle fibers, but they get tired much, much sooner than slow twitch muscle fibers. This is because while fast twitch muscle fibers have a larger cross-sectional area (bigger), slow twitch muscle fibers have many more mitochondria (little factories inside every cell that produce energy) than fast twitch muscles.\n\nNow, the strength and power of a muscle group is *directly proportional to its size*. Period. This is why fast twitch fibers are stronger and faster than slow twitch. However, since slow twitch fibers contain many more mitochondria, they are able to continue working for much longer (although more slowly and not as much peak output at any given time).\n\nNow, add to this the fact that your brain controls your muscles, and without the proper \"wiring\" in your nervous system, you won't be activating as many muscle fibers at one time as you could be if you trained more.\n\nSo back to your question: first I would question whether the bigger guys actually have bigger muscles (they might have more body fat, making them bigger, but with less muscle than the smaller guys) and then second, if we assume that they do have larger muscles, then the only way for the smaller guys to be stronger is that they have more fully developed the nervous system control over their muscles (better wiring) which comes from training closer to your limits more often.\n\nIn conclusion, the smaller guys probably train closer to their limits more often, and this makes them stronger through better \"wiring\".\n\nEdit: Sorry if this wasn't explained in simple enough terms. Also, in an interesting side note, the difference in muscle fibers is why different people have a physique that is more adapted to different types of sports. For example, people whose genetics favor fast twitch muscle fibers are typically much more successful in sports where explosive strength/speed is needed, such as sprinting, power lifting, etc, and people whose genetics favor slow twitch muscle fibers generally excel more in endurance sports such as long distance running, cycling, etc." ] }

why are local ip addresses 192.168.x.x instead of 0.0.x.x or 255.255.x.x etc?
I've always wondered and know it's a standard, but why a seemingly arbitrary address instead of something more expected? EDIT: I understand how it works with the numbers established. My question is why those numbers were chosen in the first place, which seems random.

The idea of a \"private\" network was sort of alien to the people who originally built the internet protocols with the goal of connecting all the computers in the world on a single network. You need to remember that [this was the entire Internet](_URL_0_) in the early days.", "Several network blocks are reserved for specific reasons:\n\n* 0.x.x.x refer to the \"local network\", whatever that may be\n* 10.x.x.x is a reserved local (non-routable) network. Some networks use this instead of the more well-known 192.168\n* 127.x.x.x is the local computer, which may respond to the different addresses in different ways\n* 172.(16 - 31).x.x is another local network\n* 192.168.x.x is, yet again, local network\n* 255.255.255.255 is a broadcast network\n\nSo 0 and 255 can't really be used, since they're reserved elsewhere. The first parts of the network blocks were the old network class prefixes, which aren't used as much these days but were very important when the internet was being built.", "Even though they look like random decimal numbers they're actually pretty nice looking numbers in binary:\n\n192 = 1100 0000\n168 = 1010 1000\n\n127.0.0.1 is also a special kind of IP address, which points to the local host. 127 is also a nice looking binary number:\n\n127 = 0111 1111\n\nOn older networks (before the standard was actually established), the number of ones at the start of the address (before the first zero) determined what kind of network it was. The standard was designed to maintain some compatibility with this system. Form this point of view 192 *is* all zeroes (for a network starting with two 1s).\n\nThe specifics of why exactly 162 was chosen for private networks (as opposed to any other pretty binary number) isn't really known. Somebody picked it and that's what it's been.\n\nIn a practical sense, almost any number can be used and could've been chosen. To somebody, at one point or another, that seemed like the most sensible option.", "Good question. I've taken several classes that included IP addressing and subnetting, and I don't recall hearing any explanation for why those specific numbers were chosen for the Class C private reserved subnet. \n\nConsider:\n\n192(base 10) = 11000000(base 2) = 300(base 8) = C0(base 16)\n\n168(base 10) = 10101000(base 2) = 250(base 8) = A8(base 16)\n\nAround the time ARPANET was created, many computers (e.g. PDP-8) used data and address pathways that were designed in multiples of 8, so the octal system (base 8) was a convenient way to represent numbers in those environments. Also, in IP addressing, the numbers between periods are sometimes referred to as the 1st, 2nd, 3rd and 4th octets. Maybe someone thought that because 192.168 = 300.250 in base 8, there was some sort of appeal to those \"round numbers\" as seen in octal.\n\nThat doesn't work out as neatly for the 10.x.x.x or 172.(16-31).x.x private subnets, though, so this could all be a bunch of hooey.\n\nEDIT: Also, large blocks of addresses were assigned to various government, military, university and business entities, so the private addresses were carved out of the spaces in between. At the time the designers thought that we would never use up all the addresses in what we now call the IPv4 system.\n\nEDIT II: The 192.168.x.x private address range was defined in RFC1918 as the 16-bit block, consisting of 256 contiguous Class C networks. \n\nEDIT III: TIFU. Forget octet (above) having anything to do with octal. It just refers to there being 8 binary bits in the number." ] }

So they get a spouse they eventually can't stand just to not be unmarried by 30-40 (whenever), and their kids grow up as nothing more than an obligation.

It can also refer to an action; ie, \"S/he's milking him/her for all s/he's worth!\" \n\nUsing the term milk for Almond milk - the oldest of the alternatives- could have come about for any of these three reasons. It could be because of the color, the consistency, or because to get almond milk, you need to put all the smashed up, ground up, blanched almonds in a mesh bag and slowly pour water through the bag, \"milking\" it. \n\nAlmond milk itself is a 1 to 1 alternative for regular cow's milk.

how does a web developer create a website?
You're a web developer. What do you need initially when someone approaches you to make them a site and how do you do it? I ask because I'm looking to have a relatively basic portfolio site made on my behalf but I don't know what to prepare beforehand and I'd like to be able to get my ideas across more effectively. I have next to no understanding of HTML, hosting, or how these things intertwine out there in the tubes.

For example, do you already have a design, or are you wanting the developer to come up with it? You probably have some images or other assets that you're putting into your portfolio?

Someone is responsible for all that stuff.\n\nBut a car also has a certain asthetic appeal. It looks a certain way, has lines that evoke speed and grace. It has a range of colors it comes in, amenities on the inside, a button and control layout. Someone **else** is responsible for all that stuff.\n\nIf your website is a car, the developer is the guy who makes it go, turn, and stop; the designer is responsible for how it looks and feels.\n\nSo first off, are you looking for a website designer or developer? Odds are pretty good that, unless you want your portfolio site to do something that no other portfolio site can do, you don't **really** want a web developer; you want a web designer. \n\nTake a look at some off the shelf portfolio software and see if it can do what you need it to do. Then find a designer who's comfortable putting together some sketches and plans and have them skin it up to look unique and interesting. \n\nThat's not going to be inexpensive, by the way.

The domain name (_URL_0_) simply POINTS to a given server, the same way a street adress points to your home. This way, you can change servers by pointing it elsewhere. A URL (_URL_0_/hi.html) is just a file located at the root folder of that web server.\n\nA server is just a computer that serves files. You could even host your site yourself at home on your PC, albeit unreliably. It simply checks for the requested file, parses the code in it (if there is any), then returns plain HTML that your browser can read.\n\nWhen I say some files contain code, it's usually to receive parameters and behave accordingly. For example, _URL_0_/hi.php?product=23 might retrieve product #23 from a database, then use this data in the page. This is all done before you receive the page. WordPress and other content managers work like this: content is in a database, and when you call for a page, it retrieves it from a database, and puts it in a generic page.\n\nI'm typing on a phone right now, but feel free to ask for clarification." ] }

Additionally, tv placements can be purchased. \n\nBuilding hype is easy with an unlimited budget, and most bands have a short popularity cycle so the record label will push hard to creat a buzz for them.

For example the vocalist of 5FDP were the vocalist of Motograter who toured at Ozzfest 2003 and also released the album Ghost Machine before forming 5FDP. The other members have similar stories and were touring and making albums even before forming a band together. The members were not new to the scene and had already lots of fans. Secondly the an album needs financing to produce and market it and people will not pay to make an album unless there is some great music to make an album from. And if there are problems during the production the financing might pull out and the album never gets released. So only the good music is put on albums and the rest is only played at concerts.

how do ants coordinate their efforts to make little ant megastructures?

{ "a_id": [ "d7ie3be" ], "score": [ 2 ], "text": [ "Actually, yeah. There are ant-related species where a foreman can show up and roughen up a worker for slacking off.\n\nTo quote Wikipedia:\n\n > Ants communicate with each other using pheromones, sounds, and touch. ... Like other insects, ants perceive smells with their long, thin, and mobile antennae. The paired antennae provide information about the direction and intensity of scents. Since most ants live on the ground, they use the soil surface to leave pheromone trails that may be followed by other ants. In species that forage in groups, a forager that finds food marks a trail on the way back to the colony; this trail is followed by other ants, these ants then reinforce the trail when they head back with food to the colony. When the food source is exhausted, no new trails are marked by returning ants and the scent slowly dissipates. This behaviour helps ants deal with changes in their environment. For instance, when an established path to a food source is blocked by an obstacle, the foragers leave the path to explore new routes. If an ant is successful, it leaves a new trail marking the shortest route on its return. Successful trails are followed by more ants, reinforcing better routes and gradually identifying the best path.\n > \n > Ants use pheromones for more than just making trails. A crushed ant emits an alarm pheromone that sends nearby ants into an attack frenzy and attracts more ants from farther away. Several ant species even use \"propaganda pheromones\" to confuse enemy ants and make them fight among themselves. Pheromones are produced by a wide range of structures including Dufour's glands, poison glands and glands on the hindgut, pygidium, rectum, sternum, and hind tibia. Pheromones also are exchanged, mixed with food, and passed by trophallaxis, transferring information within the colony. This allows other ants to detect what task group (e.g., foraging or nest maintenance) other colony members belong to. In ant species with queen castes, when the dominant queen stops producing a specific pheromone, workers begin to raise new queens in the colony.\n > \n > Some ants produce sounds by stridulation, using the gaster segments and their mandibles. Sounds may be used to communicate with colony members or with other species.\n\n\nDespite what sci-fi teaches us, there is no actual hive mind. The individual ants simply follow their instincts as to what the group is doing. Humans are not dissimilar that way." ] }

if music is playing in my head when i go to sleep, the same song/track instantly resumes playing as i wake up. why?
This has always fascinated me. I'm wondering if like some parts of your brain just stores whatever info is circulating as I fall asleep in it and resumes as it wakes up? Or is the song just non stop playing in my head as I sleep? What goes on in my brain while that happens? Or is this just unique to me? My family has always been heavy on music. Grand parents are conductors, almost all family members musicians on some instrument, or sing in choirs ect. so that may have something to do with it I could guess. Do similar thoughts resume for other people who are enthusiastic about other subjects possibly?

why is there a market for commodities trading?
I'm trying to understand the very basics of the commodities market, especially agri commodities. I am not entirely sure I understand why the trading happens at all. Some of the questions I have are: 1. What are the origins of the commodities market? 2. Why do commodity exchanges exist? 3. Why do people trade on spot and futures (and why is this allowed) without taking actual delivery of the commodities? 4. Where do traders come into the picture? Why isn't it a simple chain from the producer to the end customer with middlemen (wholesalers, distributors, dealers) in between? I've tried to understand this from Google searches and past Reddit posts. But all of them seem to deal with more in-depth topics. Could someone please explain like I am 5?

Some of that is released as heat.", "Friction is less to do with atoms and more to do with microscopic imperfections. When you observe a surface, it probably looks very flat to you, a macroscopic entity. However, on a microscopic level, the imperfect surface is more like a series of mountains and hills. Now, imagine two mountainous surfaces moving upon one another. The tips of these mountains grind across the tips of the other surface's mountains, and you arrive at what is macroscopically known as kinetic friction (static friction also exists while the surfaces are motionless).\n\nNofftastic is simplifying the concept. After all, when two motionless objects are in contact, there is no heat coming from the friction even though there is clearly a repulsive action occurring. In fact, repulsion of like charges is an intrinsic property of charged matter, and does not require energy to exist. It does require energy to move like charges closer, however.\n\nIn introductory quantum mechanics, there exists the notion of a minimum separation distance between two particles in a single system (a geometrical consequence, see Griffiths QM). This constraint generalizes to systems of many particles. While repulsion is nonnegligible, this quantum mechanical separation distance is largely responsible you not being able to walk through walls.\n\nThe heat is a result of KINETIC energy being converted to THERMAL energy. If we revisit the mountain picture, imagine the peaks breaking off as they move across on another. In other words, the surface is being otherwise compelled to move more than before. Since the average speed (v) of the molecules composing the surfaces increases as a result of the microscopic interactions mentioned above, the kinetic energy (0.5mv^2, notice the dependence on the speed v) increases as the objects slide across each other at higher speeds. This is converted to thermal energy, and arises observably as an increase in temperature." ] }

You just let off the gas a bit, and maybe turn in more. In a RWD car, you need to ease off the throttle, but not too much, and turn in the opposite direction. It takes more skill. That said, modern cars with stability control can pretty much negate this issue.", "Put a pen flat on a table.\n\nFirst, drag it along by its tip. Then, push it in the game direction from the back.\n\nWhich of the above resulted in a more stable path? Obviously the first.\n\nSame thing with a car. With FWD, the front wheels are dragging the rest of the vehicle behind it, resulting in a more stable trajectory. With RWD, the rear wheels are pushing the rest of the vehicle in front of it, which isn't stable in limited traction scenarios." ] }
