How do our bodies “get used to” being in very cold water (e.g. the ocean) after several minutes?	Your brain contains a region called the hypothalamus. This acts like an internal thermostat that controls your body temperature. When you jump in the ocean or a cold pool, your hypothalamus instructs your body to use more calories to raise your body temperature. Of course, it's not foolproof. If the water is sufficiently cold, your body temperature will drop faster than you can regulate it, and you risk nasty side effects like shock and hypothermia.Your hypothalamus notice the difference of temperature via your thermoreceptor around your body, so to avoid loosing any it make the blood vessel under your skin skrink, so your blood doesn't take your inner warmth outside, This make your skin "colder" and the thermoreceptor on it work mainly by difference : your skin beeing colder, and closer to the water's temperature while your receptor on the hypothalamus saying you are not loosing warmth, you won't be feeling most of the effect after these regulations. Of course there are limits to this adaptability, once your core temperature drops you'll start feeling cold again. )
Why can't Mexico do anything to stop the drug cartels?	The cartels have tons of money, local support in some areas, and a small army worth of mercenaries. Mexico is up against a very difficult task. America's hunger for drugs is what finances the cartels, and Mexican leaders have repeatedly asked us to reconsider our drug enforcement policies.
When dropping a counter into a slot from the exact same postion on a pegboard/plinko/pachinko style game what is it that stops the counter from falling the same way everytime?	If you could drop the counter into the same position in exactly the same way and the game was in exactly the same state then it would fall exactly the same way. However, you can't do that because even though it may seem like you are doing things the same way on the large scale, on the small scale there are very tiny variations which cause a different outcome. Think about firing a gun. If you are shooting hundreds of yards away then even a tiny movement of the gun, too little to see without looking down a scope, will cause the shot to land a large distance away. Air movement along the path of the bullet will change where it hits, temperature differences in the barrel, etc. can all impact the result. In the same way the game has a lot of variables which make things happen differently each time.
why does cold water taste better than regular water?	It's just a cultural thing. The Chinese prefer to drink hot water. If there are contaminants or bad-tasting substances in the water, though, it'll taste better cold simply because you'll taste it less.Cold water kind of gives me a stomachache actually. Prefer room temperature.
What does having insurance on a priceless artwork do?	Priceless is a subjective term used to describe something that is one of a kind and no reasonable amount money can replace. Realistically, every piece of art has a price . For insurance purposes, a guarantee of compensation for specified loss, damage, in return for payment. If you buy a “priceless” hand carved art for $1000 and then spend $400 to preserve and display it, you may want to insure it for all or part of your investment.They get some money back at least, up to whatever value it was insured for. Something is better than nothing. It's the same principle as life insurance: even if you believe your own life is priceless, it's still nice to leave your family something.
How can a solution to a problem suddenly pop up?	Subconscious mind solves it for you with all of the acquired knowledge and experience. This won't happen if you've no knowledge.
how do you take an idea to invention if you have no applicable talents?	You need a partner. It is very doable if you are willing to do work. I.E research what materials are needed, how much it will cost. Applicable uses, just research what you can research. Get a patent. then you can do a lot of stuff. You can PM me for more info. BTW don't talk about it too much and just do. You don't want someone stealing your idea. I also agree with the other people in this thread. An idea isn't worth shit by itself.
Why did everything become so minimalistic? Buildings, art, etc..	In Western culture, the era from 1916 to 1945 marked a turning point. The old European ways did not seem to be working -- that culture seemed to be collapsing on itself in a wave of wars and mass murders. Some artists responded by trying to throw away everything and start with a new, more modern way of doing things, free of the old cultural baggage. By coincidence, this new simplified style turned out to be very efficient to manufacture or build, especially by machine. So it was both a new fashion and a cheaper way to do things. Thus it became very popular.
Why do we need less sleep as we get older?	We do? I don't know about you but I am tired all the time", 'Define "Older"? 25? 35? 45? 55? 65? I'm "Almost Over The Hill", and I love me some naps.. I have a friend who stops for naps on his way home from work.
How is it that SD cards stay the same size but manage to have such varying levels of storage?	Because the actual part the data is stored on is tiny. Think of it like this; a school buss looks just as big from the outside when it's carrying one kids as it does when carrying 20 kids.
Why is my inner monologue an arsehole?	I'm not sure what kind of answer you're looking for. We don't know what your inner monologue is saying. It's your own unfiltered thoughts. So apparently you consider yourself to be an asshole.Funnily enough I just talked about this over in another thread somewhere. Everybody has both good and bad inside of them. Everybody. There's basically a bell-curve of good/evil distribution where most people are on the fence. What keeps most men "good" is both the societal construct of morality, and our own ingrained sense of ethics. A large part of the time we perform good actions, or at least not-evil actions. The evil side of us, though, lurks below the surface and usually announces itself via your "inner monologue", which is as good a term as any. A lot of us, whether we will admit or not, experience such things on a fairly regular basis, whether we realize it or not . The overwhelmingly vast majority of us, however, adhere to our internal ethics - the ones that say murder Bad - and don't do anything evil. I don't wish to convey the opinion that we're all just raving psychopaths one straw away from gunning down everybody we can see - though it might seem that way in this country sometimes! - but rather to demonstrate that though we may do good, we don't always think good. It's kind of a yin/yang thing. That one's personal ethics are shaped in large part by society's values du jour isn't really germane to my point, but it is worth considering in a broader scope.
How did people in the olden days construct buildings that were multiple stories high without the use of machinery like cranes to lift and place materials?	Pulleys and inclined planes have been used since a long time. Pulleys to lift loads and inclined planes to push stuff up or down. Much like today's modern cranes, pulleys did the same except using man power.
Are Volvos actually safer than other cars?If so why?	Yes they are. If internet is not lying then one of Volvo's co-founder's wife died in car accident, and safety was the highest priority from the start. They invented three point seatbelt and side airbags.
In the recent Nuclear Weapons Treaty, why did the Netherlands vote in opposition?	There are American nuclear weapons stored on a Dutch air base. It was public secret for a very long time, though it was confirmed in more recent years. That sort of thing would be against the treaty. Currently, the government is not taking steps towards removing these weapons / ending this cooperation with the States, so they also cannot really vote in favour of a treaty like that.There are countries with nukes and countries without nukes. Then there are countries that don't have nukes but allow their allies to store some nukes on their land. The Netherlands falls into the 3rd category. Obviously, countries with nukes don't want to give them up , so when non-nuclear states come up with a vote to ban nukes, nuke countries don't want to play ball. The Netherlands allows nukes on its land, so would be naturally opposed to a weapon ban, but they had a vote and decided they would at least show up to the weapon treaty vote rather than not showing up at all. They showed up and voted no.
Protien Folding and how it relates to Alzhiemers and related conditions	A protein is a very long chain of amino acids. Amino acids are molecules with different shapes and components that can be strung together. A denatured protein has no defined shape and flops around like a piece of string. However, the different amino acids making it up have different functional groups, which are the parts of the molecule sticking out of the protein chain. These groups fall into two main classes. Some really love water, and some really hate it. So if you plop your floppy protein in water, [it will arrange itself into a ball so that all the water-hating groups are surrounded by each other and all the water-loving groups are in contact with the water]. Then some groups really like to form bonds with complementary groups. So two different points along the protein chain really want to be in contact with each other. This is the driving force that turns a loose floppy string of molecules into something with a definite shape. However, there's only 21 different amino acids and proteins are made up of hundreds or thousands. So your lysine at position 25 is connected to the glutamic acid at position 39 in the well folded protein, but there's also a glutamic acid at position 59 it can interact with. If the wrong interactions dominate, you end up with proteins that ar ethe wrong shape. And shape is very important for proteins because it affects how well it can bind other molecules, store energy, and perform its function. If it's the wrong shape it won't do anything or might even do actively harmful things.
Why does adding water in a beer bottle make the pitch of the sound higher when blowing in it, but adding water in a wine glass make the pitch lower when tapping on it?	The difference is in the medium making the sound. In the beer bottle it is the column of air, in case of the wine glass, it is the glass itself.
What makes crack addicts pull out their teeth?	What makes you think that crack addicts pull their teeth out? Pulling out teeth isn’t easy, and pulling out your own teeth would be next to impossible unless you’re completely impervious to painThe crack fucks with your hunger and you basically just crave sweets like M & Ms or chocolate covered peanuts.The teeth disappear from the edges inDon’t the chemicals in the crack just make the teeth rot?
Why do wall chargers seem to charge iPhones faster than computers, xbox... etc	To add to the other replies, current is drawn by the phone rather than pushed by the charger, and the rating of the charger is how much can be drawn before it shuts down/overheats/burns out. By default, the phone will only draw a low amount of current . The charger has a way to signal to the phone that it's able to give more current , and then the phone will draw a higher amount, generally 1 to 1.2 Amps. Most phone manufacturers have settled on a de facto standard, but Apple decided on a proprietary standard so an iPhone charger won't charge an Android device quickly, and vice versa.
If a high-security building like The Pentagon or The White House catches on fire, do firemen have instant clearance to access any area necessary?	This was actually a problem with the 9/11 attack on the Pentagon. There were reports of unofficial firefighters and military personal touring the site without actually helping. Their motives are still unknown although a few were arrested. Rather quickly a perimeter was setup and all personal who required access were issued a badge. All that was needed at first was to show ID. Some 8,000 badges were issued. After, a list of people with pages was compiled, sectioned and assigned a leader who then cut back on assigned badges to only those that were critical. Essentially, a regular fire would have a perimeter and authorized persons setup quickly as the respective counties personal would already be on file and could be issued clearance quickly. A big event like a plane crash confuses everyone for a bit. TL;DR: Yes, Firefighters have free roam for evacuation purposes but will be quickly screened before being let in, although depending on the situation at hand people could sneak in before a perimeter was set up.
Why does my hair grow to a certain length a few weeks after I shave my head; but remains that length and never goes past my shoulders even after years?	Your hair doesn't actually remain a certain length. Depending on which part of the body, your hairs can only grow to a certain distance, once they reach that distance, they fall out.
What is aggregate efficiency ?	You can figure out how much energy is in a barrel oil, say by burning it in an enclosed system seeing how much the temperature increases. But that is not going to be the same as the amount of economically useable energy it provides. It takes energy to pull it out of the ground, energy to ship it, to refine it, to distribute it, energy to keep the lights on in the gas station you buy it at, energy lost to the inefficiencies of an internal combustion engine, and energy to mitigate the environmental damage of any of the previous steps. The aggregate efficiency of that barrel will be the ratio between the energy it provides, and the energy needed to make it available.how much work gets done over how much work can get done. when you boil a pot of water, you are putting energy from the burner into the water. but most of the energy from the burner is lost. it heats empty air. in more complex systems, there are tons of little losses. a typical car has over 10,000 moving parts and all of them are losing energy. if your interest is in using that engine, you don't care about those parts, you care how much energy you put in to how much you get out. whatever the difference is is the aggregate of all those tiny loses.
How come animals can eat off the ground? Does germs not effect them?	Not all germs cause disease. You can eat off the ground, too, and getting a parasite is very possible, but most bacteria and viruses don't survive outside a body for a very long time. People ingest more germs than they think they do, and for the most part, its unavoidable.Heykittums answered this well, but I feel like it should be included that by spending their lives eating off the ground, animals also expose their immune systems to the parasites, bacteria and viruses that live there, which helps prevent infection later in life.The floors you find in wealthy countries are not good places for germs to live. Dirt floors, common in most countries, are a completely different story, the ground has tons of parasites and bacteria. The Mexican government had a big program recently where they covered the floors of the poor with concrete, in order to improve their health, and they had pretty good results . Floors of finished wood, linoleum, vinyl and carpet are not good places for germs to live. I don't eat off the floor regularly because I don't like eating dust and hair, but if I drop a cookie or something I'll brush it off and eat it ", 'You are assuming that eating from the ground would make you sick. Are you sure this is true?
How do cell phones only pick up signal from their specific provider?	It's because of the frequency bands; they are regulated by the Federal Communications Commission. I do not know who shares which frequency in Amerika but here in Germany we got 4 mobile networks each got a different owner and a different GSM900 frequency range. * D1 / Telekom\t13–49, 81–102, 122–124* D2 / Vodafone\t1–12, 50–80, 103–12* E1 / E-Plus\t975–999* E2 / O₂\t1000–1023, 0 2007 E-Plus and O₂ paid for their frequencies 22mio € ea for 9 years ownership. It's equal to your radio, if you are listening to 92,2 you do not get the signals of other stations because of frequence.
How do people see beauty? For example, what makes a rose beautiful but a Cactus not?	I find cacti beautiful, its all subjective. Beauty is not in the object, it is in your perception of it.It's really a case of individual likes and dislikes. Personally I find deserts and prairies beautiful because the wide open spaces mean room to roam, wind in my face and air to breathe. My SO thinks they're ugly because there are no mountains or trees.
Why does the moon have a ring around it some nights?	was it a rather cold night? I believe that the Halo may be a light refraction caused by ice crystals in the air, similar to rainbows.
The 9th amendment to the US Constitution.	The US government has "enumerated powers", which means that it can only do those things which are specifically laid out as legal for it to do. Civil rights, which the first eight amendments protect, work precisely the opposite way. The ninth amendment basically says that, as opposed to the powers of the US government, citizens\' rights are NOT enumerated, and a provision for a specific right should never be interpreted to mean that those are the only rights that a citizen gets to enjoy. Unless there are laws against something, a citizen can do it; unless there are laws allowing it, a government cannotThere was concern among some of the founders that the Bill of Rights would lead to someone saying \'well the Bill of Rights doesn't specifically say you have X right and therefore you don't\'. The Ninth Amendment was added to deal with that concern, since it essentially says "just because it's not here doesn't mean it's not a right"IANAL It clarifies that the default assumption of rights is in favor of the people, not the government.
How are sentences by judges that are aimed at making an example out guilty parties not a violation of "Equal Justice Under Law", and therefore unconstitutional?	Each type of crime has a valid minimum and maximum sentence. As long as the judge stays within these guidelines, it is 100% legal.
it's 90 degrees fahrenheit outside. It's going to rain. Is the air more humid just before it rains or just after?	Actually it's most humid WHILE it's raining. The air has so much water in it that some people even use umbrellas or stay indoors completely.
When you bump, scrape, or acutely injure yourself, why does it instantly feel better simply by putting your hand over the injury?	Your nerves are mostly sending either pain or pressure signals to your brain. However, they can only send one signal at a time, and pressure takes priority over pain. So when you get hurt and apply pressure, your body thinks "ok there's pain and pressure but since we can only send one signal to this meatbags brain we'll send pressure, and ignore the pain for now"This is called [Gate Control Theory,] basically when you put pressure on a wound, the pressure takes priority over the pain sensations as your nerves can only transmit one or the otherI believe it is to do with pain receptors keep reporting pain while remaining exposed.It’s why paper cuts can hurt so much, as they don’t tend to bleed, leaving pain receptors exposed for longer. Covering the wound would attempt to do the same job as bleeding would do. Edit: Wikipedia page about paper cuts: _URL_1_Basically the "touch" signals take priority over the "pain" signals so you feel less pain in order to feel your hand over the injury.
My rights, or lack thereof, when encountering the TSA in an American airport.	You are required by law to comply with legal orders of border control agents, the TSA, and police. You are not obligated to incriminate yourself. So you do not have to answer any questions they ask you. If you have entered a border control facility they have the right to open and inspect your luggage. They have the right to search your person. If you are traveling through a security checkpoint they can ask for your permission to open and inspect your luggage and search your person. If you refuse, you can be denied entry to that checkpoint. They have the right to refuse to let you proceed through a security checkpoint if you fail to comply with their lawful requests. They have the authority to deny you entry to the United States, or to arrest you and take you into custody if they believe they have probable cause. If you are arrested you have the right to have an attorney present while you are questioned. You have the right to remain silent. The authorities must present evidence in front of a judge within 72 hours that you have committed a crime by making a specific charge against you. If you do not have the proper visa to enter the United States, you can be held until such time as transportation can be arranged to send you back to your point of origin, or your home country.
How can ocean water and air temperature be the same temperature, but the water feels so much colder?	You don't feel temperature. You feel rate of heat transfer, which is greater for the water because of its higher thermal conductivity. The same thing is true when you put your hand in the oven at 350F: in air, no problem. Touch the metal, problem.Water has many more molecules per volume, which means it can transfer heat at a much better rate than air. So if the air is 70 degrees, some heat flows from your body to the air but if the water is 70 degrees, heat transfers much faster making you feel cool
2001: A Space Oddessy.	There is much more to the monoliths than they get around to in the movies. Read the books, they cover a LOT that's not in the movies, I can elaborate in PM, don't want to spoil the books if you may be interested in reading them. Of better yet, if you want book spoilers, read the wikipedia entry for the novel. _URL_0_", 'Evolution. Life. All that messed up shit at the end was about a higher lifeform trying to communicate to us. As they are so advanced we cannot begin to comprehend their existence.
What drew people to attend the Grateful Dead concerts over and over again?	The GD started their career as a band playing live gigs, most notoriously at the Acid Tests. These were like the very first rave parties, initially when LSD had not yet been made illegal. People would come and drink the spiked Kool-Aid, and there would be a variety of amusements, often including the Grateful Dead noodling around on their instruments trying to make music. They weren't very good initially, and they usually just jammed, rather than playing "songs". The Acid Tests are well described in Tom Wolfe's wonderful book "The Electric Kool-Aid Acid Test". This started the core of the Dead's following, as some people would follow them around from gig to gig, often taking LSD and dancing and having a great time. It was pretty much a continuation of the Acid Tests. Many of them would make just enough money to survive selling stuff in the parking lots and campgrounds before the shows . Most people, of course, didn't follow them around like this. But their shows were a great place to be with a mellow community of hippies having fun, listening to good music. A lot of people would go to their shows any time they came near, because it was just like going to a huge party with people who were cool with whatever you were into, as long as you weren't hassling anyone else. Being weird was normal, and being normal was weird. You could pretty much sit around and smoke dope without much fear of getting busted, because everyone was sitting around and smoking dope. Strangers would offer you a toke, and it was only polite to offer the folks around you a toke if you could spare it. And at their core, the Dead was always a jam band. Sure, they played songs. But some of the best music was what the songs meandered into. TL;DR - The Dead were a way of life for a few people, and a mellow party for a lot of other folks.
Because you have to swear to tell the truth in court then why is "I swear I'm not guilty" not a viable defence?	The court is not assuming your truth, they're asking you to pledge to tell the truth and will punish you if you do not.
Why does 1% battery last longer?	Battery remaining is pretty much just a guess. Your phone measures the voltage and makes a guess as to how much of power is left. If you rarely or never let your phone run all the way to where it cuts off from lack of power, it will slowly start measuring more and more inaccurately. First it will think 1% remaining is empty. Then 2%, and so on. Eventually, it's estimate of remaining battery is significantly far from correct. When you finally let it run all the way to empty, it will seem to last longer. It thinks it's empty at 5%, so it's shows 1% remaining when you really have 5% remaining. Since it still has power, it still runs, but the estimate is wrong. Because of this, battery drain slows down as it nears empty.
What is a CO-OP?	A co-op is any independent organization where people cooperate for mutual benefit. REI is specifically a consumer co-operative, as opposed to a housing or worker co-op. In this case, the shareholders and consumers are essentially one and the same. If it helps think of Costco/Sam's Club . You purchase a membership for REI, which gives you one vote. Like shareholders in a corporation, you use these votes to elect a Board of Directors, who then hire the major executives, like the CEO or whatever. Usually in a co-op, unlike a corporation, you can only ever have one vote but idk if that's the case for REI. Then the CEO and other executives actually run the company. A much smaller co-op might be directly run by the consumers/workers/residents themselves.
What will actually happen in the event of a financial collapse?	Credit will dry up in a financial collapse, causing banks to call in their loans and the people who can't pay are forced to sell. This applies to individuals, businesses and the government. The world runs on credit, so next to no credit slows the economy down. Then over time everything tends to correct itself and pick up the crumbs after", 'Think of it like this. no money means no jobs, Jobs like growing food, Driving busses, Police.
Why do all contests have a NO PURCHASE OR PAYMENT NECESSARY TO ENTER OR WIN clause ?	If a purchase is necessary, it becomes gambling, which is illegal in most states. As such, in order for contests to be legal, they have to include an entry option that doesn't require the entrant spend money. Usually the requirements are overly cumbersome , so no one really bothers. It's worth noting that most contests are more to generate publicity than direct sales , so just having the advertisements and getting people thinking about the product is usually enough.Depends on the contest. The example you mentioned is not aimed at increasing profits, but rather to create positive advertisement. People see that they have a chance of winning something for free, and they take a liking both to the contest and to its host.
How does the compass on the iPhone work?	Non-douchey answer: There's a chip inside that can sense magnetic fields and can use the field to determine the direction the phone is facing. There's really no way to explain simply how the chip works inside, as it uses fairly advanced principles of electromagnetism, but it actually works very much like a real compass, but digitally rather than analog.
Why are some videos framerates 23.976024 fps (as opposed to exactly 24)	Basically it solves the problem of fitting 24 fps source material onto a 29.97 fps NTSC video signal. 23.976 fps is 80% – or four fifths of 29.97 fps, which is the frame rate of the NTSC video signal. By slowing down 24 fps ever so slightly , you get 23.976 fps. This then allows four frames of source material to be spread over five frames of NTSC video using a technique known as [three-two pulldown.]
How is Uber legal without following the same liscensing rules as taxis?	Basically, because a taxi is defined as a car that you can stand on the sidewalk and hail. Legally, if you don't provide that service, you're not a taxi. This was upheld in a recent lawsuit against Uber, and the judge ruled that Uber didn't meet the definition of a taxi, since they can only be hailed from the app. They're closer to, say, a limo service where you call and schedule a trip, which generally aren't classified as taxis.The licensing for taxis is for "cars that you can hail on the street corner". There are different, less stringent restrictions for "town car" services where you schedule a trip ahead of time. Because Uber cars aren't going up and down the street looking for passengers, they're technically not taxis but you can schedule one for pickup right now, so they're an effective replacement for them even though they don't technically match the description.Since they don't pick people up off the side of the road, but rather are privately ordered via their app, they are classified as a private car service rather than a taxi. They are not subject to the same rules. Problem is that ordering a car via app is faster and easier than hailing one on the street, so it pretty much makes taxis obsolete.
Why are people mad about Microsoft's Windows "spying" but not Google's same "spying" in Android?	Everyone knows Google is spying on them. It is part of their business model, and Google is up front about it. They even give you web pages that show you how much they are spying on you. Microsoft is less up front about it, and has more of a history of doing dodgy things without telling users. Also, they are an older company, so a lot of their misdeeds occurred before people were as used to getting spied onHistorical context. Windows computers have never had "spying" before, but now people's computers that they bought years ago have now had "spying" forcefully added to them without permission. In contrast, Android phones have had "spying" from the very beginning and people bought them with full knowledge of their business model. The contract is identical as when you first bought it; nothing has been changed without your permission.
How come some city streets in the US like in NY emit large amounts of smoke/steam from underground unto the curbs yet you never see this phenomena in european cities?	Because the buildings are heated with steam that sometimes escape. We don't have that in Europe._URL_0_ District heating systems pump steam through certain areas, from a central heating installation. The system in New York is more than a hundred years old, and hence is less insulated and more prone to leaks.
How exactly does our body produce electricity?	At the very basic level, it is caused by Sodium and Potassium ions, which are differently charged, and using these ions to create channels of chemically-induced electric current. It would be extremely inefficient if we wanted to use it as a sort of biological battery. Our current chemical batteries have much better storage and voltage and so on. ", 'Chemical reactions. More specifically, electricity is just the flow of charged particles, and the body is set up to keep oppositely charged particles on opposite sides of a cell membrane. If I recall my biochem correctly , in the body this is mostly caused by negatively charged potassium ions being attracted to positively charged sodium ions across the cell membrane. Particular proteins regulate the flow of negatively charged potassium out of the cell as it tries to get to the positively charged sodium. This flow of charged particles creates the electricity. Caveat: I am not a scientist, I just paid marginal attention in class.
Does this lawsuit make the family (and possibly the lawyer) some of the richest people in the country?	No. [ABC News]: > An attorney who persuaded a Texas jury to award one of the largest civil verdicts ever says he and his clients don't expect to collect any of the $150 billion judgment, but they hope it helps persuade prosecutors to seek charges against a man they say doused a boy with gasoline and set him on fire.
Why do water pipes not burst after you turn the sink/hose off? Shouldn't the pressure from the water backing up cause this?	Imagine that you have a bucket full of water. Poke a hole in the bottom of the bucket, and water will start pouring out. But if you plug the hole, the bucket doesn't burst from pressure backing up. The pressure is constant, and does not increase when the water stops flowing. The same is true with water pipes: The pressure is caused by gravity pulling water down out of water towers. When the water stops flowing, the pressure just levels off.
What exactly happens in a Windows computer when you delete system32?	System32 contains all the components to get your OS running, deleting that would just result in getting stuck in the bios. This doesn't happen when you are an active user in the OS, only when you restart your computer after trying to remove the folder 'system32'.
Why do humans get time suppression during tragic events?	Time appearing to slow down is actually an illusion. The part of our brains that helps us feel emotions, the amygdala, becomes more active during times of stress. This causes our brains to ramp up memory recording, making our memories in the moment of a car accident or similar situation much more dense and detailed. Compared to our normal memories, it seems like memories that detailed must have been made over a longer period of time than the quick few seconds of the crash would allow. This makes us feel that time slowed down. But it's just memories temporarily being set into "4k recording" mode, so to speak.There was an experiment performed to test this: The researchers took volunteers to the top of a 150 foot tower and had them fall backwards off it into a net. Every single test subject reported that it felt like it took much longer to fall that the 3 seconds it actually took. This is what gives the impression that time slows down when you're under stress and for a while one of the main theories was that when you're under extreme stress your perceptions 'speed up' to give you more time to react to the danger. However, to test this, the researchers put a device on the back of each test subject's arm that flashed up numbers, but the numbers only appeared for a split second just too fast to see. So, if their perceptions were actually sped up, and they were actually experiencing time in slow motion, they would be able to see the numbers. This didn't happen. No one could see the numbers even though if their perceptions had sped up to the rate they reported, they should have. What it was found to be is that the part of your brain responsible for creating memories becomes much more active under stress basically 'recording' the experience in far more detail than normal, and the richer and more detailed the memory, the more time the actual event appears to have taken.
Why do I, sometimes, really not like some people for, seemingly, no reason?	You're probably not a terrible person. Everyone has a few little things that just rub them the wrong way. Not everybody is socially compatible. The polite response is simply to tolerate those people who you don't like and observe the social niceties when necessary and avoid them the rest of the time.
Why do smartphones have two cameras on them and not just one double-sided one?	Its a tad more complicated than just make it double sided!. It would significantly increase the cost and bulkiness of the camera area, both things people care about more than the frontcam image quality. Its for selfies and posting to Instagram, people aren't taking panoramic landscapes with it. Quality doesn't matter much.
How does burning happen? Do food-calories "burn out"?	Pretend like you have a jar of marbles. The marbles/jar in this case are molecules/electrons. You start shaking the jar of marbles , now let's say you shake it hard enough to the point that some of the marbles break through the jar. The new marble goes flying out and just happens to another jar of marbles which then allows that jar of marbles to get excited and release some of it's marbles, and the cycle continues. Now pretend like you packed the jar full of marbles, it's now going to take more energy to get the marbles to break free . Now pretend that the marbles are all various colors and sizes , and that different colors of marbles are attracted to each other while others aren't. So as you're releasing the marbles by applying energy, they come off with various amounts of energy and impact their surrounding marble and marble jars accordingly. Now as the marbles are moving round, they can also break into smaller marbles and join up with other marbles to form bigger ones. Burning something sends a lot of energy into the other marbles and breaks them apart into other sized and colored marbles that no longer have the functionality of it's previous form.Heat is not a "transfer of fast moving particles". Rather, temperature is how much the atoms and molecules in a substance are jiggling. Things at higher temperature are jiggling more than things at lower temperature. _URL_1_ Any time you use an apparatus to make some substance hotter, all that is happening is that the apparatus is causing the atoms in the substance to jiggle more. There are many different ways this is accomplished, depending on which apparatus you use. If you understand that temperature is just different degrees of jiggling, then it's easier to understand what a fire is. _URL_0_
Why are smartphones coming out with a 64 bit processor but < 4GB ram?	Well if you've already hammered out your 64bit support before you need it for the RAM that's always nice, of course. There are some other advantages, though none I would imagine are Earth-shattering. 64bit CPUs would also generally use 64bit registers, which means you can potentially keep more useful information in the CPU at a time.The new features in 64-bit cores are also used in non-phones along with the addressing. So you might have a server with > 4GB of ram using the same ARMv8 architecture as your phone even if they physically have different CPUs. Some of the added features typically found on 64-bit processors - Ability to manipulate 64-bit values in a single cycle. Handy for public-key crypto- More general purpose registers- Usually feature wider and deeper SIMD register files- Usually feature crypto instructions ', "Having more RAM is only one benefit of 64bit processing, and it's one worth ignoring because it's honestly difficult to use that much RAM on a phone unless you just carelessly leave all of your apps open draining your battery. And its best to just prepare for 64bit to be necessary so that old apps still work when 32bit is phased out.Absolutely! CPU's also link to memory-mapped files , not just RAM. So what's the difference? RAM is used for the active process, MMFs are used to store background processes. So to apply that to a phone: You're browsing Reddit on your phone and get a picture sent to you on Snapchat. If you switch apps from the browser to Snapchat, Snapchat takes over the RAM and your browser's information is put on hold in a MMF. When you switch back to the browser, the process reverses and Snapchat goes to a MMF and your browser resumes using RAM. Note that MMF is also known as "virtual ram".
Why do fries get soggy the next day?	The inside of a fry is moist cooked potato. Deep-frying dries and cooks the outside to a crisp. There is nothing keeping or blocking the inside of the fry seeping out moisture to the outside. Over time, this process makes the outside layer moist and soggy.
Is it possible to drink water at a constant rate such that you can just keep peeing indefinitely?	No. You can drink in excess to the volume of water you excrete, and this can in fact even be fatal if done excessively enough. The result is that your extra-cellular fluid will be low in solutes, and osmosis will shift it into your cells, causing swelling in the brain, what is sometimes called water intoxication. Sufficient swelling can result in death.
When I play guitar my left hand is fluent, fast and accurate but when I use it for anything else it's basically useless. How come?	You've taught the muscles to work in a certain way as you learn to play. Muscle memory. If you went and did normal day to day stuff with your left hand you will become more proficient at anything.
Why do windows sometimes act like mirrors	Glass allows most light to pass through it, but because it's still naturally reflective ) you will always have some light reflected back. If the light coming through the window is brighter or more intense than the small amount of light that's reflected , you'll see the light from outside. If it's dark outside, you will see the light reflected from inside.
How does radiation from the Fukushima plant affect the fish I eat in North America?	It doesn't, really. The levels measured are incredibly tiny, nanosieverts. You'd get more radiation from spending time in Denver or eating a banana.
Why do some sudden noises scare the crap out of us, while others go nearly unnoticed?	. If your ears cannot detect or is not expecting a specific sound the brain defaults to "this sound is foreign or out of the norm so it must be bad" and releases some adrenaline to help you fight the the threat or go away. In the days of primitive humans, a foreign or unusual sound usually meant danger, so the brain evolved this response to help fight or flee from the perceived threat. Since your brain knew the second time around the sound wasn't a threatening sound or you might have been expecting it your brain simply ignored the signal to release adrenaline, since the brain wants to conserve as much energy as possible; again this comes from speculation and my limited knowledge of how the human body actually works; fellow redditors free to correct me if I have misunderstood or misinterpreted anything.
Why are things like countries referred to as females?	Other languages have grammatic rules in a way that differentiates male, female, and middle form . Each noun belongs to one of these forms. Doesn't matter if it's a living thing or just a thing. And doesn't even matter if the object is of male nature or a female nature. It has more to do with a system or a classification, mostly with the endings of words. So that everything is structured nicely. It really has more to do with the phonetics of the noun. Not so much with the meaning. In such languages, the form of the noun also affects adjectives, verbs, etc. used with the noun depending on the noun's form. So for example, if the word "phone" is male and the word "car" is female, then in phrases: "nice phone" and "nice car" different forms of the word "nice" would be used. That's why kids growing up in such societies are taught how to differentiate the forms of nouns. So that they can use the correct corresponding forms of verbs, adjectives, etc. This carries over to names of countries among other things. From that, English-speaking people exposed to foreign cultures grab snippets of those languages/cultures, translate them literally, and use them in a way that no longer makes sense, when used in the English language. And then, some English-speaking people push it even further for dramatic effect. "Ain't she a beauty" -- when talking about a ship, for example. And here we are :)
How exactly did the rotors on the Wehrmacht Enigma work?	I hope you get to read this. Look for a YouTube channel named singingbanana the guy is a matematician and he has an awesome explanation on how the enigma machine works. Found the link for you _URL_0_
Whats the psychology behind the "silicone baby" phenomenon on YouTube.	1) Some people who have lost children use them for grieving 2) Some people who can't have children use them as surrogates 3) Some people just like them, they're considered collectible
How to pay off students loans?	Interest is a percentage that you were told when you took out the loan, and every month that much percent of the amount you have left to pay is added to your bill. To pay off the loans you probably have to contact the company you took out the loan from, look for a contact number on the monthly statement you receive for the loan in the mail or online.
Why can't humans see in the dark?	Our eyes are stimulated by electromagnetic radiation in a specific range - we see the "short" end as violet, the "long" end as red, and everything between as various colors of the rainbow. Any shorter wavelengths start moving into the ultraviolet range, which doesn't stimulate our eyes. Same with wavelengths longer than red - they go into the infrared range. So tl;dr: Your question is backwards! It's not that humans can't see in the dark - it's that humans have defined "dark" as the absence of light in the visible range. Edit: Technically, it comes down to the _URL_1_ and _URL_0_ in our eyes. We have 3 types of cone cells that respond to light in the visible range as defined above. If we had say, a 4th that could detect UV light, then we 'd see an entirely new color beyond violet. Some animals can see far outside of the range that we can, so "dark" for us might not be for them. Rod cells are more sensitive to light and aiding in low-light vision, but we simply don't have as many as some other animals, and our eyes don't let in as much light.It's not so much the limited range of the EM spectrum but the maximum size of our pupil. Even within the visual spectrum, we can't handle low dim situations. If our pupils were twice as large as they are now, we could see in low lighting conditions a lot better. The ability to catch lots of light depends on aperture size. Having a large aperture is important.
Why is the patriot act viewed negatively?	The purpose of the act was to deter and punish american terrorists. In reality it was used by the FBI to ignore the constitution and things like \'probable cause\' to investigate people unrelated to terrorism. This included, drug traffickers, homeless people, visitors to las vegas, and a webmaster regarding copyright infringement. > One criticism of the Act is that "other purposes" often includes the detection and prosecution of non-terrorist alleged future crimes. _URL_0_', "It's wrong to do harm to others. But some people do it anyway, and we have to protect one another from those people. The only way to do this, unfortunately, is to do harm to those dangerous people . We don't want everyone deciding for themselves what's enough, so we make laws and assign a very limited number of people as law enforcers. But we don't just give law enforcers permission to do harm, we give them very strict rules on how, when, and why. These rules are very important; they make sure we always know how when and why our law enforcers are committing harm, that way we can make sure no more harm is done than necessary. Now, the Patriot Act changes the current rules, it gives law enforcers permission to do much more harm than usual, and to anyone, with fewer explanations.
How do software engineers keep track of all the code in a very big program?	[Let me introduce you to git] Git is a version control system that acts as a repository for your source code. It has features like version history, branching and merging, code rollback, all the things you need to properly handle large coding projects. Git is one of a number of version control systems, and it is one of the most popular . Other examples include Perforce and SVNI'm not a master programmer by any means, but comment, comment, comment. You can use them for anything-- titling different sections of code, describing what they do, or numbering parts, all of which you can search later with Ctrl+F. I would always think "ehh, I'll remember how I did this." Nope.
how do exploding bolts work?	The application I know explosive bolts are used for is aerospace engineering: they are used to separate rocket stages since they are lighter and much more reliable than other mechanical separation methods, especially in a zero-G environment. You can see that [here]. Explosive bolts contain explosive charges in a specific pattern, usually on the circumference of the bolt, that are wired to a remote detonator. The wireless signal is received by the remote detonator and through the wires reaches the explosive and ignites it. The bolt is often designed to have an intentionally weak spot where all the energy from the explosions releases and snaps the whole thing in two.
What is it about the color black that absorbs light and converts them into heat?	it's physics. and you got it the wrong way 'round. objects appear black to you BECAUSE they absorb the electromagnetic waves we call light. that light carries a certain energy with it which gets absorbed, which is then converted to thermal energy aka heat. If thats not what you meant, please elaborate a bit on the question
What is the scientific reasoning behind some substances that have a reverse tolerance?	"Reverse tolerance" or drug sensitization is a real thing that can occur with certain drugs or alcohol. If you think about alcohol in particular, over time you build up a tolerance for it and it takes more alcohol to get you intoxicated. Supposing you continue to drink heavily, you can damage your liver, which can lead to a reduced tolerance or "reverse tolerance". Some drugs require a sensitization period, in which your brain/body needs time to build the proper neural connections and uptakes in order to feel the full effect of the drug. Antidepressants/antipsychotics tend to fall under this category.
How do spiders get to the top floor of apartment buildings?	They can climb. They can also get blown along by the wind until they land on a higher floor of a buildingYou’re assuming it started on the ground floor when it well could have been born one story from the top. They can also climb well.
Why do big threads from the default subs never appear on my front page until they're 8 hours old and have 5000 comments already?	Because of the way you have it sorted - by "Hot." It takes the subs you're subscribed to and picks the hottest ones, so big subs like pics and adviceanimals show the highest scored threads. Switch to sort by top - hour and you'll see a lot more, relatively quick revolving threads. Be active on them and comment/contribute to the things you like. Some will likely work their way to the big boy front page.
Why is it more expensive to eat healthy?	Your premise is somewhat flawed; it is not necessarily more expensive to eat healthy. It certainly can be, if you buy certain types of raw ingredients, but does not have to be. Industrial scale food processing is extremely efficient, so a lot of prepared food is cheaper than the make-it-yourself equivalent so if you try to eat the same stuff as just build your own, it usually doesn't work out. However, if you adjust how you cook and eat it's fine.
What should I ask college student programmers if I want them to be able to design VR simulations for my research team?	Do you have an actual computer science department at your university? I'd give the project description to a professor in that department and ask them to advertise. If what you want is simple enough, you could even ask them to make a single example and see who does what you need the best to make the rest? That said, this isn't really an ELI5 question. I'm just answering because I didn't want you to feel lost if I could help it. You can try one of the computer science/programming reddits for a more specific answer, too.
How can IQ be so confidently ascribed to racial characteristics (i.e. hereditary)?	Simply put: 1) There is really no consensus amongst psychological sciences that IQ tests can be considered to be an accurate measure of anything, other than performance on the specific and abstract tasks that constitute IQ tests. 2) Even when using an arbitrary test like an IQ test, it has proven completely impossible to isolate and filter out learned and acculturated abilities. 3) It is thus impossible to attribute any results of IQ tests on a population scale to genetic traits, as the social and learned effects cannot be discounted. The claims to heritability do not thus necessarily point to genetic inheritance, IQ scores are far more likely to be passed on by upbringing. 4) IQ tests are a product of a pursuit - the assessment of intelligence - that is controlled and influenced predominantly by white, upper-middle class, academia. So, unavoidably, the results will be a bit skewed towards white test-takers.There is a lot of controversy around IQ tests even being valid at all. Different cultures learn different things, and one of the criticisms of the standard tests is that they are written for a middle class white culture - if you are part of that culture you will do well in an IQ test. So if you take a Kalahari bushman and give him an IQ test he might score terribly. However, take a middle class North American and drop him in the Kalahari naked and alone and tell him to survive and he won't do very well. TL:DR an IQ test measures a fixed set of things. Just because someone does not know what is in that set does not truly reflect their intelligence - only their knowledge related to the categories in the test.
Is there any significant difference between different brands of water?	Significant, I wouldn't say. The source of the water changes its composition, and therefore also the taste. If two brands get water from the same source, they would be practically identical, unless one of them really screwed up the bottling process. Unless you have a serious mineral deficiency, I can't imagine one brand being measurably more healthy for you, and if you had a mineral deficiency, you should get a proper supplement for that anyway, not bottled water.My mother recently started a bottled water facility, from what she told me: The processes that are run to treat the water can be different from brand to brand. Just to name a few: reverse osmosis, ultra violet rays, filtering. Also where they get the water from, some come from springs , others from treated water. This also affects the taste of water as well. ~~Also, you cant sell 100% clean water because just like in a pool you would get algae after some time inside of the bottles.~~ Edit: As some of you pointed out, and my mom explained me better: Algae may show up when the purification process is simple, it doesnt purifies the water enough. Also, once you open a bottle of water it gets contaminated with air and bacterias, its really bad to let an opened bottled of water for long periods of time, specially if it gets hit by the sun.There are differences. Poland Spring really is spring water from Maine. Dasani is the local municipal water supply run through some filters and bottled. Mostly its a matter of taste. Which most people don't pay enough attention to make a difference.
When I have a cold, why does my nose often continue to feel blocked after I have blown it thoroughly?	The blocked feeling doesn't only come from mucus, it's usually inflammation of the sinus cavities and nasal passage.When you have a cold, your sinuses become inflamed and swell to the point where all the built up fluid can't drain. This causes a lot of pressure and the "blocked" feeling. This swelling is also what leads to a lot of children getting ear infections after a cold. The fluid can't drain through the sinuses so it drains through the eustachian tubes that connect to the inner ear.
A compulsory music license.	From my understanding , it basically means that if you pay a copyright holder for the license to cover their work, they're required by law to allow you to do so. In other words, they shut up and take your money. EDIT: Clarity.
Why do some "antibacterial" agents cause resistance, and some don't?	Right, I don't know the specifics regarding triclosan and tea tree oil but I can take a crack at this.\r\rAntibiotics and antimicrobials work, in their broadest sense, by either killing bacteria or preventing their growth. To do this they must interfere with some process that the bacteria need to live or to grow. If the bacteria evolve a way to bypass the process or have it function anyway then it will have evolved resistance. If the antibiotic only targets one process then the bacteria only need to bypass one issue in order to become resistant, but if the antibiotic has multiple targets then the bacteria has to evolve counters to all of those before it is resistant. If it doesn't counter them all then it will still be killed, so bacteria have to develop all the necessary counters at once. This doesn't make it impossible for them to do so, but it does make it much less likely. There are other ways in which this works as well, if the process targeted is more core to the bacteria's function, it will be more difficult to evolve a resistance than if you targeted something that has an easier work around. Sorry if that isn't very clear, I can try to explain further if you like.\r\rAs for your side question, yes, every single antibiotic runs the risk of causing resistance. The simple act of killing off most of a given bacteria puts a massive selection pressure on those bacteria. Bacteria are evolving constantly and any one bacterium might develop a resistance to a given drug at random, if it's only one bacterium of many then it might not really get anywhere, it might even be outcompeted by its sister bacteria for food or something and die, but by killing off all of the non-resistant bacteria you are removing the competition and allowing it to thrive. As for alternatives, antibiotic is a very broad term, anything that kills bacteria is by definition an antibiotic. Bacteria don't become resistant to ALL antibiotics at once and, even if a type of bacteria develop a resistance to antibiotic A, they can still be treated using other antibiotics.
Why does being tickled make us laugh when it is such an unpleasant sensation?	The short answer is we really don't know. Of course, [people have their guesses], and it seems to be that it isn't a naturally occurring physiological response driven by a biological imperitive. Most of the hypotheses point out that you typically 'learn' about tickling through a parent/child interaction. Indeed, if you feel like reading up on scientists scarring childeren for life, [Cracked] has 6 good tales, one that tried to prove whether tickling was a physiological response or a social learned response.
How is it that prisoners can earn law degrees while serving time, but on the outside people go into six-figure debt to get the same degree?	Offering prisoners the chance to study in prison lowers their chances of returning to a life of crime afterwards and improves their behaviour while inside. That said it is not the same degree. Do you really think prospective employers are going to look at a harvard degree and a prison degree and are going to go 'yes, these degrees are exactly the same in terms of worth'.
Why do we humans get so easy problems with their teeth while animals don't brush their teeth at all and most of them do fine their entire life?	We have terrible diets that contribute to damage to our teeth. Many animals also don't live as long as humans, and that damage can take a while to really compromise your teeth. And ultimately, if an animal's teeth go bad, which does happen, that's typically the end of their entire life. You don't see the bad teeth animals running around because they have died from complications to having bad teeth, like disease and starvation.Humans live decades longer than most other animals so when out teeth are getting bad, we still have like 40 years to go. If an animals teeth go bad they are probably dead within a few years. We have very sugary diets that contribute to tooth rot1) Our diets include a lot more sugar than we naturally evolved for. 2) Our diets include a lot more acid than we naturally evolved for. 3) We live 2-4 times the amount of time that we would "in the wild".I'm not really answering your question since others have done that, but I'm answering an anticipated follow-up question. It was quite common for our ancestors to die from tooth infections, but that's the sort of thing that doesn't usually happen until adulthood, after we have had the opportunity to reproduce. For that reason, there isn't a lot of selective pressure for teeth to last much longer than early adulthood. They don't have to last long enough to let you grow old in order to be an evolutionary success, just long enough for you to pass your genetic material to a new generation.
If any, what would the differences be to your body if you lost weight by burning calories through exercise, as opposed to eating the same amount of calories less?	As far as just plain weight loss goes, there would be no difference whatsoever. Your body requires somewhere between 1500-2000 calories per day just to survive adequately.You burn X and consume Y. If X > Y you lose, if Y > X, you gain, regardless of how you create that imbalance. However, muscles mass takes more calories for your body to maintain than fat tissue. So if you lose it through exercise, you're probably also building muscle. More if you're doing muscle-centric workouts like lifting. So over time you will end up losing more from the exercise since adding more muscle will increase the amount of survival calories your body needs to consume each day. But it's also a lot easier to just eat less than it is to burn 500 calories in exercise. The human body has grown to be ridiculously efficient in how it uses its calories, a huge benefit that served us well for thousands of years, and has only recently become a drawback. You really don't burn all that much from working out by itself. This is why they always recommend diet and exercise to lose weight. Diet for easily dropping the amount of calories you consume and exercise for adding more muscle and general health so that you're not just burning more, but increasing the rate in which you burn them over time, creating a snowball effect. tldr; Eating less loses fewer calories but quickly while exercise loses more calories, but much more slowly. Do both.
Do film companies pay theatres to show their movies, or do theatres pay film companies for the rights to show their movies?	It's a shared pool that works out roughly like this, the ticket price is split between the studio and the theater at a percentage 1st week: 90% studio / 10% theater 2nd: 80/20 3-5: 60/40 etc Specific movies and specific studios may have deals that alter the percentage for each week and timeframe, it's all negotiated, and these are estimated but it's a good rough base of how it works. The theaters still collect all the money on concessions, that's where they make the bulk of their profits.Theaters pay them, either for a one time fee, or studios get a % cut of ticket sales, usually 90% of opening week sales, 80% of second week sales, and so on, most likely stopping at 50/50.
Why is it, that on the same amount of food consumption, I feel fine to exercise, but feel empty to edit an essay?	The empty feeling when thinking about the essay is a psychological process. There could be many reasons your brain wants to avoid it. This most likely has nothing to do with food intake. Sounds like small dose of the maladaptive coping mechanism psychologists call avoidance. Plain old procrastination is different. I'm guessing it's the coping mechanism because you have some deterring "feeling" associated with it.Assuming it biological and not psychological then possibly glucose. The brain needs a lot of glucose to do serious work like essay writing. It doesn't have a storage capacity like other cells so whatever is in the blood and whatever the liver has stored is all there is. For exercise muscle cells themselves store glucose, in the form of glycogen, and can produce energy from protein and fat when that runs out. None of this is possible with brain cells.
Why do people listen to music with earbuds in while driving a vehicle that most likely has a stereo in it?	They could be listening to music from an audio player which can't connect to the car stereo . Or they could just be using their headphones to talk to someone on the phone. And where I'm from it's very illegal.I think in most cases they are just using the earbuds as an earpiece for their phones. A lot of earbuds these days have microphones somewhere on the cable so you can use them as a hands-free set.
Why are head-lice a 'kids thing' that seems to only exist amongst groups of younger aged children?	Because kids, when at school and play they get their heads close to others. Adults, consider it rude/weird/childish to do that. While the lice may spread from child to adult, it is less likely to happen between two adults.
Why does the toast get crunchier when it cools?	The steam evaporates off, so it's less moist.Food keeps cooking after you remove the heat source, since the heat is still in the food itself. Water will also continue to be evaporate.
How do computers know what time it is?	They have an internal clock, a lot like a wristwatch. It keeps track of the time. There's even a small battery on the motherboard to keep track when the computer is unplugged.
Can someone please explain the sunk cost fallacy?	Imagine you 've had a car for the last fifteen years, and that car is a piece of shit. It breaks down every few dozen miles, it smells gross, it looks like shit, and you're constantly pouring money into it. The Sunk-Cost fallacy is where you would be more likely to keep the car and keep pouring money into it than to spend a whole bunch of money on a new car. The thinking is something like "I 've spent so much money on this car, it 'd be stupid of me to buy a new one." This is also extremely common among gamblers, who might keep playing a machine, reasoning that since they 've put so much money into it already, it's bound to pay off eventually. TL;dr, It's where you think that it's more beneficial to continue doing something, despite that something being obviously detrimental, because you're sure that if you keep doing it, you'll get a returnThe answer above me is right, I just wanted to add another example. If you're waiting in line for something for a really long time, and you want to leave but you think to yourself "well, I 've waited here so long, I might as well stay" that is a sunk cost fallacy. The time you 've spent in line is gone no matter what, you should only evaluate your next decision based on the future
What's the difference between the different tiers of gasoline and is it really worth the extra money for premium gas?	Higher grades of gasoline are refined more carefully to give them a higher octane rating, which means they burn more consistently and are less likely to "knock" under the higher compression in high-performance engines. Unless your car's owner's manual specifically says you need to fill the tank with a higher grade of gasoline, it's a waste of money. Check the owner's manualThe different tiers refer to the fuel's octane rating. The higher the octane rating, the more compression the fuel can take before it ignites. This is important in engines with a high compression ratio . If you put a low octane fuel in a high performance engine the fuel will ignite prematurely in the cylinder causing a phenomenon known as "engine knock". This is a bad thing. On the flip side, putting higher octane fuel in a low compression ratio engine will have no real effect as the engine is not designed to utilise it properly. To answer your question, is it worth the money? If you have a high performance car: YES. If you dont have a high performance car : No, it's a waste of moneyI concur with Mobyhead but add that using premium in a car designed for regular can actually give worse performance and mileage because the ignition system can fully ignite the air fuel mixture.
What happens when we sleep? How does sleeping “recharges” us?	Someone can explain this much better, but it basically gives your brain and body some downtime to do some repairs, make some different proteins, etc. It also gives your brain time to process the events in your day and serves as a break from constant stimulation
How come New York City is so expensive yet 8,000,000 people live there?	Uh, can you explain your logic of why 8 million people living there would prevent it being expensive?
What causes SAD (Seasonal Affective Disorder) and what helps?	Though not definite, some think SAD is a caused by a lack of sunlight during the winter months. People have come to this conclusion since countries that are further North are more likely to report higher rates of depression during the darker months. Melatonin is a hormone that our bodies produce. It is important in our wake-sleep cycle, making us drowsy. Light inhibits the production of Melatonin. So, during the winter months and especially the further North , we are exposed to less light and thus increasing the production of Melatonin. Blue light has the effect of halting production of the hormone. To help mitigate SAD, one can use light therapy. This is pretty much a box with a bulb that produces the necessary wavelengths that one stares at for a period of time with the goal of impeding the production of Melatonin. One can also force themselves outside more often, especially on sunny days, in an effort to get as much light as possible . Exercise is also an option. _URL_0URL_1_
Why do the windows in the back seats of cars not go down all the way like in the front?	It's not to keep children in the car. It's simply that there isn't enough space inside the door for the window. The bottom of a front car door is bigger than the window, so it can go entirely inside. The rear doors have a cutout for the rear wheel well, which keeps the window from being able to go all the way down.It's both actually, though one does seem to come after the other. Originally, as /u/tank5 said, the rear doors have a cutout for the rear wheel well, so that prevents the window from going all the way down. A simple design "flaw" if you want to call it that, that could be fixed but isn't worth the hassle of redesigning the whole car just to have a couple less inches of glass. Now, companies started making it a standard, saying that the windows provided a sort of safety for younger children, making it harder for them to unbuckle their seat belt and go out the window. Is it all that effective? Perhaps. I can't say as I'm no expert, but if you think about it from the point of view of a customer, if you have a child, you're going to want the car that has more safety features plain and simple, whether or not those features really help all that much. So to keep up with competition, it has somewhat become a standard I suppose you could say. tl;dr There isn't enough space, but it could help keep children safe so they 've kept it anyways.
The current American immigration problem	The unbiased report is that the politicians are still arguing what they think needs to be done. And since they're arguing and arguing and arguing about it, nothing gets done. In the meantime, many poor and desperate people from the impoverished countries of Central America will continue to immigrate illegally to the USA. They will do the jobs which most US-Americans refuse to do, like agricultural work and cleaning jobs.
Herman Cain's 9-9-9 Plan	It regards taxes. 9% tax on corporate income, 9% tax on individual income, and a 9% national sales tax across the board. of coarse this is impossible, but people are having fun with herman, and I think he is having fun too9% Corporate Income Tax 9% Personal Income Tax 9% National Sales Tax The elimination of loopholes would make large companies that can typically lawyer their way around taxes start paying. The national sales tax would enable the federal government to tax money they can't otherwise tax very efficiently now, such as money brought in from other countries or money earned illegally or paid "under the table" rather than through the payroll system. It is believed by some that those two factors, combined with the simplicity of the new tax code, would increase the federal government's income and make it harder to avoid taxes. It's believed by others that the net tax burden to the poor would be increased, because they don't pay income tax right now, however, others argue that the elimination of other taxes the poor do pay would make up for that difference. Some people refer to it as a 27% tax. That is incorrect, because people don't pay corporate income tax. Corporations do. It is also a little-known fact that Mr. Cain intends the 9-9-9 plan to be a bridge to the FairTax. [[source]] [[Info on FairTax.]] On a purely personal note, I am in favor of almost any plan that reduces or eliminates the gamesmanship of our present tax code, therefore, I am at least intrigued by Mr. Cain's proposal.hmm did you ever play sim city? You know how taxes start out at like 9% for residential, commercial, and industry? It's kind of like that
Why is it that some days after my hour long drive home, I cannot remember the journey at all?	The human brain has a bit of an autopilot function. However, with this said, if the brain detects a problem, it pops out of it. That's the reason why you start paying attention just as the guy cuts you off, from what I understand.
Why do a lot of hospitals have religious connections?	For centuries medical care was provided by churches and temples. This is because for many religions care for the sick is a major command of their faith. This tradition has carried on into modernity and a lot of hospitals are heavily funded by religious groups, and many are physically owned by them with the religious group actually paying to have it built and owning the landSick and dying people are in the right frame of mind to contemplate God. This means they are a good source of people to convert or pull more deeply into the religion. People who are cured are often thankful and promote the religion to others. People who die are more likely to leave money to the church, and their families are often more willing to support the church as well. For this reason, many religions tend to focus on healthcare as a pillar of their charitable activitiesBecause there was a time when hospitals were funded mainly by churches, not governments, and the institutions kept their names
How are the elements in the 7th row of the periodic table created in a lab?	Particle accelerators fire streams of one type of atom at another type of atom. The kinetic energy is enough overcome the repulsive forces, and smash the nuclei together, creating new elements. It is nuclear fusion, not chemistry, so while you can't change an element through chemistry, you can through physics.
Why does licking your lips make them dry out?	Moisture is kept in your skin by a thin layer of oil. This includes the skin on your lips. When you lick your lips, it wipes away those oils, allowing water to evaporate from the skin, causing them to dry out.
