What exactly happens between the director of a movie finishing filming, and the movie coming to the cinema? it seems like a long time.
|
One thing they do is post production. It's when they put all the scenes together, add sound effects, and special effects. This is where they also add the final touches before distributing the film.

If the Fukishima Nuclear Rods are such a huge problem - Why can't we just send them to space?
|
I'm not sure a lot of people understand how difficult and complex launching into orbit is. Other people have already covered some reasons such as the possibility of the fuel rods reentering the atmosphere, which would happen if the orbit wasn't very high. First of all, launching anything into space is **very** expensive, I believe right now the cheapest is about $5000/lb into low earth orbit. In the event of a launch anomaly, the fuel rods aboard an exploding rocket would pose a far greater threat than they do right now. This was a concern during the launch of the [Cassini-Huygens probe] because of the 3 [RTGs] it contains as a power source. **tl;dr It is impractically expensive, and would pose a much greater threat than they do on the ground**

How has SRS not been banned for sub invasion and deliberate downvoting?
|
Back in high school, people would be nice to me because I couldn't understand if they were either being nice to me, or they secretly were making fun of me. They knew it annoyed the hell out of me because I have this inability to accept that some people were/are actually nice people. Its something like that.Because they are officially against it, even though it can never be enforced. Also is that even against the rules?

With the moon's gravity factoring all the world's waters, why doesn't it seem like it signifigantly changes anything else?
|
Technically you're being affected by the Moons gravity, the Suns gravity, and the gravity from the other planets in the solar system. The Earth has the strongest hold on you, and trumps all other forces. So you're experiencing those forces, but because we're on Earth, we don't really notice it compared to the gravity that the Earth hits us with.

When they say the stock market lost 20 Billion dollars in a day, where does that money go?
|
/u/Lokiorin and /u/14thMarines are both right on the money, I just hope to make it a touch easier to understand. And I wish to say I am going for a very simple explanation here, so no need to be too aggressive guys. The stock market shows the value of a company. A traded company is divided into any number of shares, which each have a value. If you added the value of all these shares together, they give you the value of a company. The market decides the value of each share based on how much people are willing to pay for it. So it depends entirely on how the market feels about a particular company, how much they think it is worth. Emotions come into play and people make decisions. But, nonetheless, a company still does, produces or owns something, this is how they generate money, but at different times things are worth different amounts to different people. Say, for example, I try and sell you an orange on Monday and you have just eaten a huge meal, entirely based on oranges. You would not be willing to pay me much for my orange, say 10 cents. But, if you didn't eat for three days, and I tried to sell you that orange on Friday, I could probably get a dollar out of you. knowing I can sell you that orange for a dollar on Friday, but that you were only willing to pay 10 cents for it on Monday, what is it worth on Thursday night? I could say to myself, hey I have a dollar because that is what this is worth. But then, if you get hit by a bus on Friday morning , then I am back to owning just one orange. The valuation I had for my company is no longer the case, and most of that value is wiped off. But, as you can clearly see, I never had a dollar, I simply had the products and capacity to earn the money, and that way my company was more valuable.

What makes them so sure there nothing of worth on the moon?
|
It is largely accepted that the moon was formed by a mars sized body crashing into the Earth and expelling enough matter from the Earth to lump together and form the Moon. Thus the moon is made from basically the same stuff as the Earth - just without an atmosphere and without tectonic movements and well, biology, to evolve it over time. There's not much really interesting to its composition - we can basically dig down on the Earth and find the same kind of stuff. The interesting stuff about the moon can mostly be gleamed by looking at it - i.e. it is interesting because it shows how many asteroid impacts it's had in its lifetime - something that the Earth must have had swell but most evidence of which has long been scrubbed away by tectonic movement and nature. I guess you could also say that the moon's relatively high amounts of Helium-3 compared to the Earth could be interesting but again, that can be looked at through telescopes, in lunar rocks already collected on the moon or lunar meteorites.

Why is Compton still such a dangerous/impoverished place even though it has put out multiple multi-million dollar musical talent?
|
I've never been there, but here's my guess: None of the systemic issues that caused it to be the kind of place that it is have changed. A few people just made a lot of money and left.For a true ELI5: Those two things are effectively unrelated to each other to the point that asking the question is the only true metric of ignorance. The world does not genuinely function in this narratively-apealing manner, and the slightest consideration of the variables should reveal that. Others will tell you why, but the question itself was answered already by not being a valid question.

How does smell work? What physically composes it, and how do we perceive it? How can a smell linger so strongly even after you thoroughly clean something?
|
Your nose is filled with special receptors that particles bind to. I believe we have some 300 binding sites, dogs have like 20,000 . When a molecule attaches to a site, the nerves associated with that one kind of site fire. The sites are shaped so only some kinds of molecules can fit. The molecules, though, can usually fit in several different kinds. The exact, unique combination of which places a molecule attach to is interpreted by your brain to give you a sense of smell and tell you what, exactly, you're smelling. There are some smells we're very sensitive to, like sulfur . In the case of sulfur, compounds containing sulfur are usually found in dead and decaying stuff , which are full of nasty bacteria and parasites so we have evolved to avoid them . Depending on the smell, the molecules might be very resistant to breaking down, so cleaning just moves them around instead of getting rid of them. There might also be a lot of them left floating in the air, even after you've cleaned up the source. Products like Febreeze work by 1) overpowering the bad smell with a good smell and 2) bonding to the bad smell so it no longer fits into the same smell receptors.

what makes a belly button an “inny” vs an “outie”
|
The hepatic portal vein is a fairly large vein in unborn babies that is part of the pathway to keep blood away from the fetal lungs. It instead sends the baby's blood through the cord & into the mother to be cleaned and oxygenated. When the baby takes it's first breath and the cord gets clamped/cut, a tiny hole between the upper chambers of the heart closes and the hepatic vein is no longer necessary so it collapses and becomes a kind of ligament. As this vein dries up it pulls on the belly button. A vein that had a lot of collagen and was fairly stretchy doesn't pull super-tight and you get an outtie bellybutton. A vein that had a little less give, you get an innie. You can see the remnants of this vein on an adult liver as the band of fibrous tissue that divides off the loves of the liver btw. Just an added cool fact.After birth they tie off the knot to the belly button. If they cut after the knot you are an outie. If they cut BEFORE the knot you are an innie. Outies do not have a hole innys do. There are also people who do a lotus birth. Look it up on youtube. They leave the belly button attached to the placenta until it falls off naturally after a couple days. This process always leaves an outie.Definitely an umbilical hernia. My daughter was born with one. The doctor said if it didn't heal by the time she was four or five she would have to have surgery. It went in somewhat but no surgery was required.

How is the pattern on a key chosen? And how are they all different so that two keys cannot open the same door?

So every key would unlock every lock from that brand. Customers could get their money back.

How do obvious scams like "you won a free trip to the Bahamas" make money. With as cliché they are, who would actually fall for it?
|
This is usually automated spam and is usually just re-purposed scams that someone else was doing where the code was altered slightly for the sake of benefiting the new attacker. There are repositories all over the internet for scammers to grab old spam bots and such. They can also get hoards of email addresses from data dumps which they can automate. For them, this is really easy to do. They'll take their re-purposed spam messages and automate them, often sending hundreds if not thousands of emails out. The success rate in insanely low as modern spam filters easily deny these messages from making it through, but there are successes and when your sending thousands of spam messages a day a success rate of .01% still has results.

What makes a computer better for a specific application?
|
Most custom built gaming computers use i5 processors because they are cheaper. Current games don't utilize many processing cores, so paying more for an i7 would be unnecessary because games wouldn't utilize the hyperthreading An office computer is kind of a generic term. If your job is mostly word processing, then you don't need a 700+ dollar gaming computer, just something bare bones. However, if your job involves rendering, encoding, or any other intensive processes that can utilize multiple threads, then an i7 processor might be worth it. For a server, an Intel xeon would be optimal for multitasking, as one of the Xeon processors has something crazy like 16 processors and 32 threads. Apologies for anything that might be incoherent. I'm on mobile.

Why do you have to pay taxes on a house you build yourself, given that you have already paid taxes on all materials and outside labor?
|
I don't know if you're aware of this, but the idea of a tax on the unimproved value of land only, rather than the value of buildings on top of it, has been around for a long time and is quite popular among economists: _URL_0_", 'It sounds to me if you are confusing "Sales Tax" with "Property Tax." Whether you build the structure yourself, or have a contractor/builder do it, you will pay the requisite sales taxes on the materials that go into its makeup. Once the building is complete, and as long as you own the property, you will continue to pay property taxes to the appropriate entity to support the surrounding infrastructure and community services Additionally, the tax rate on the land you purchased will increase because you have "improved" it by building a home.you're paying taxes on the land. like it or not, your property and the space it occupies are serviced by the local government. even without utilities and conveniences, your continued use of that space creates certain burdens on those around you. on this principle, governments tax land as a proxy.

Why has Arabian nations been able to capitalize on their oil resources and become massively wealthy while Africa hasn't?
|
The vast majority of Africa is not developed at all. Here's a little task for you . Head over to Google Maps. Zoom in randomly on the US, Europe, China, or Japan, and scroll around until you find farmland. I'll bet it's not going to take you long at all. You actually have to try pretty hard to find somewhere *without* farmland. Then, zoom in anywhere in Africa, and try to find farms. Not just the deserts, but anywhere in Africa. It will take you quite a while to find anything resembling a farm on most of the continent. The biggest concentration of farms can be found in Egypt and along the southern coast of South Africa. Any others you find will be a comparatively small smattering of random farms around the larger cities. What do farms have to do with oil? It's all about natural resources. Africa isn't really taking advantage of theirs. They have lots of land that's largely untouched and undeveloped. They have huge amounts of fresh water with Lake Victoria and Lake Tanganyika, but they aren't taking advantage of it for irrigation or drinking water, despite a lot of their people going hungry or even starving to death. If they're unable to use the more available natural resources to their advantage, they're definitely not going to be able to get at the difficult ones such as oil.

What is Ron Paul's economic plan and why does he love the gold standard so much?

How exactly are hybrid and electric cars better for the environment, when most electricity is generated through coal and nuclear energy, which are bad for the environment?
|
Clean energy actually makes for a large portion of the energy supply in some places. And that's basically it. A gas guzzler is 100% dirty, with a hybrid, and even more with an electric car, at least a part of the energy used is gained greenishly.
|
If the nuclear deal that Obama proposed is so good for Iran, why haven't they taken it?
|
An important reason why Iran haven't accepted a deal is because they probably don;t have much faith that Obama can deliver on his end of the bargain in terms of lifting sanctions. This fear is exacerbated by the presence of a Republican congress and a right wing Israeli government unwilling to support any negotiations . Furthermore, they probably want to continue negotiating in order to make sure that they can get as good a deal as possible in terms of energy production vie nuclear, and in terms of sanctions lifting.

If we are a democracy why can't the population take a vote on certain bills
|
Because you are not a [direct democracy]. Here in Switzerland, if we don't like a new bill and if we find 50k people who also don't like it, we can force the government to do a national vote on the cause. We can also invent our own bill and let the people vote over it, if we find 100k supporters within 18 months.

At the end of WW2, what happened to ordinary German soldiers? Did they just put away their guns/gear and resume civilian life?
|
So, after World War 1 the Germans had an army called the _Reichswehr_ which was just a standing army, probably perceived on the same level as Canada's army . When the Nazis took over, they rebranded it the _wehrmacht_ and gave it a lot more power/weapons to show off Germany's might. But, this was mostly just regular army folk serving their country, not a bunch of people _trying to destroy the jews_. There was a branch known as the SS that was more akin to Hitler's personal guard and these were often forces that _were_ about Nazi sentiments and attitudes. After the war, many of these people were captured and put on trial. Many more were executed by people who discovered who they were. Many, many MORE escaped and may have lived on to die naturally, helping top leaders escape to live in Latin America. Josef Mengele died of a stroke in 1979 in Brazil. He escaped Germany by pretending to be an ordinary member of the Wehrmact infantry, whom the allies were not interested in punishing personally[.]", 'Yes, pretty much. My great uncle fought for Germany and moved to Ireland after the war and started to build model train sets.

Why the last sips of beer taste worse?
|
Well, this probably depends on what type of beer you're drinking. I would say there are most likely two reasons though. 1) The beer warms while you're drinking it, allowing more of the flavors to come out 2) Taste fatigue: beer can be complex. There are sugars , sometimes citric & acetic acids , and alpha acids, from the hops . The more you drink, the more your various receptors are responding to these flavors. Bitterness, in particular, can have an overwhelming effect as you eat or drink more bitter compounds. This results in taste fatigue, where it becomes difficult to taste anything else but the bitterness. Edit: to clarify point , the lower quality the beer, the more off-flavors will come out when it warms up.

Why does college tuition cost so much in America?
|
for the same reason that housing prices skyrocketed: easy money sparks inflation. the government almost literally hands out student loans to anyone. since the government is the one paying tuition upfront and they can pay any amount of money, this enables the schools to charge any amount of money. this has other consequences as well. the student loan bubble has created a student body that can stay in school forever. this enables schools to set ridiculous graduation requirements, as well as offer totally useless majors to kids who don't know any better. the end result is a generation of college grads who have no skills and a mountain of debt.

Advantage of credit cards over debit cards
|
> Also, debit accounts also offer an overdraft facility and the charges are lower than credit card charges. In the US this is almost never the case. If you put $500 on your credit card and pay it off at the end of the month then there is no fee. However, if you overdraft your debit card then you get penalized immediately. Further, the penalty hits you every single time you overdraft .

Why is the difference betwwen choosing to be gay or being born gay relevant in the debate on homosexuality?
|
There isn't one . Some people feel that, if it isn't a choice, it's totally fine . The other side assumes it must be a choice, since they feel it's wrong, and therefore it must be a choice; of course, this assumes that no one is ever born with an inclination to do something wrong . Ultimately, it really doesn't change the arguments; people just feel that arguing one way or the other will give a sort of visceral appeal to their position.It is relevant because if it is a choice, some people believe you are choosing wrong, and that can be changed.It's not relevant. Close-minded people think that others should change to suit their beliefs. Simple as that. If they think homosexuals have a choice to make they can label it as right or wrong. If they think homosexuals are born that way then there's just something wrong that needs 'fixing'--still, to suit their ideals.

Why are some films still not available for rent, even years after their initial film premiere?
|
Because the film's distributors have decided they can make more money selling the film than renting it at this point in time. Disney is especially notorious for creating false scarcity so they can issue Collectors Editions of their films later on.There are online services that rent that movie, including [Google play] and [Cineplex].This doesn't explain anything re:studio releases, but, seriously, get to a library. Mine gets new dvds and blurays out within 2 days of release. If you're too cheap to pay and too lazy to pirate, it's a goldmine. Doubly so if have kids and just borrow the same movie until they get sick of it.

How much does someone actually have to lift to tip over a 1000 pound car?
|
I've had a kinda-similar question in my brain for a while. I used to work for a book publisher, and I routinely moved pallets of books that weighed 1000 pounds or more, with a manual pallet jack. Obviously, I can't move 1000 pounds on my own, but I was moving it with no additional motors, so I was effectively moving 1000 pounds by myself. How could I figure out what I was 'actually' moving, weight-wise? Is that even a valid question? How much force was I exerting to move that 1000-pound pallet?

What does LSD do?
|
It's truly an indescribable experience, but I can confirm that it is far from what you experience when you're high on weed. Lights and colors become extremely vivid, and everything is much more interesting and captivating than it should be. Depending on how hard you're tripping you can see colors and waves, and if you move your hands in front of your face, for example, the motion can be blurred. In my experience I also felt like I was looking at a stranger when I looked in the mirror. It's like you see yourself from an entire different perspective crazy stuff.its nothing like weed. Its full on strange. very hard to describe. Its like waves under your eyes and feeling that you dont quite fit in your skin but its ok as you can stretch things around so its ok.Please don't compare LSD to weed. Totally different.LSD has the potential to change your look on yourself, the outside world and everything almost completely. It opens another dimension which can be truly a thought changing experience. I can easily believe how it could damage the mind if taken too much. In "normal" doses it is very interesting: Colors, sounds, feelings intensify, can mix together. Wind or music can seem to make houses blow with wind or move with music. Things, items, nature, people can seem to open completely different meaning and outlook - this might be good or bad. You can possibly see a completely different perspective to things that you never thought possible. "tour guide" who is sober is recommended during trip to handle communications with people if needed. I can recommend starting at home and later move to a familiar techno club. In contrast to THC it is completely different; THC makes you relaxed and slow and lethargic. Of course different experiences in different people are possible, in bad and in good.

In cooking what does a pinch of salt actually do?
|
Salt is something we can taste, so it helps to enhance flavor. However, it also can block bitter tastes, so for food like eggplant or cucumber it makes them taste far less bitter on the tongue. For this same reason, you often add it to chocolate - especially hot chocolate, to mask the bitterness and pair it with the sweetness of sugar. It has many other uses, like drawing moisture out of meat, causing it to dry more and brown better, thus enhancing something called the Maillard reaction, which produces hundreds of flavor compounds that don't form on wet foods. Finally, it can add a physical texture to foods.Sidenote: the tiniest pinch of salt in a cup of coffee diminishes bitterness significantly. Old British Army trickSalt and fat excite our tastebuds, as they're synonymous to a quick, filling meal. Some people put a "twang of salt" on watermelons, or in chocolate to give an extra layer of excitement to our tongueSalt is an important component for the functions of neurons.

What stops private entities from pursuing a weapon of mass destruction project?
|
There have been private entities who have created weapons of mass destruction. _URL_1_ _URL_0_ And of course the terror attacks using Anthrax in 2001. WMD is labelled as Biological, Chemical, and Nuclear weapons. I'm looking at your question being more specific about why hasn't a private entity manufactured nuclear weapons and here is an answer. Weapon Grade Uranium is present in about .7% of all Uranium dug up. This weapon grade Uranium has to be strained from the other 99.3% of Uranium to a point of around 90%. It gets even harder though as there is another isotope that is crap that looks and is almost exactly the same. The good Uranium isotope is called 235 and the bad is called 238. Imagine them as identical twins. Now you have a picture of two identical twins so now imagine twin 238 has ate a fudge Sunday and weighs a fraction of an ounce heavier than the other. That is how the Uranium is filtered from the other by slowly and painfully trying to pull the slightly nearly almost as heavy identical twin from the other one. As you can imagine that is really really energy intensive and expensive requiring a specific type of people who have been trained on how to do this. These people are also very limited and in high demand so trying to acquire them is going to draw a huge amount of attention. I have to go but I'll be back to finish up later.

Why does my computer prompt me for a JAVA update at LEAST once a day?
|
According to this [Java Version History] listing it's only been updated roughly once every couple of months for the last two years. I think that if you're getting more notifications than that then you might have several different versions of java installed and they're each requesting an update. Or there's a corrupt entry in your registry which is preventing java from telling your computer that it's updated properly. I'd try uninstalling everything to do with java and then just downloading and installing the latest version .You should not be receiving several update notifications per day for Java. Java does not release updates as often as you are claiming to receive notifications, so the updates must not be installing the updates properly or something else is foobar in your system. Java certainly does update frequently, but if you are updating correctly you should receive in the ballpark of one notification weekly; definitely not one or two per day as you are experiencing.Are you sure you're actually following the updates through to completion? I've noticed that quite often you'll get a UAC prompt to download the update, and then it'll sit quietly in the taskbar waiting for the update to actually be installed. If you don't do the second step, then you'll get the update prompt every time you turn your PC on.What /u/drminicus said, but try this: Go to the control panel, find Java , start it, find the tab called "updates", and set it to check daily, weekly, or monthly. Or even never, if you 'd like.

What are the benefits of a smaller processor nm? like from 32nm to 14nm to 10nm?
|
While less overall heat is produced like many have said, I'd like to add that there is more heat produced per area. I know its not a benefit but its a fun fact to know. An example is if a 20nm processor took up 25 units of space and produced 50 units of heat but a 14nm only took up 16 units of space but produced 40 units of heat there would be a reduction in heat created but an increase in heat per surface area. This can create unintended challenges.

how do we know the laws of physics are constant through out the observable universe?
|
We can see very far, and nothing we've seen indicates otherwise. For example, all stars in the Universe follow the same cycle, and produce the same spectral lines. Galaxies all have similar shapes. There are no instances where an object appears to exceed the speed of light. So it's pretty safe to assume that gravity and chemical reactions proceed in the same way, otherwise we would observe different spectral lines in stars, and see different galaxy structures.

- Why do pulley systems work?

Why do women who live and work in groups get synchronized menstrual cycles?
|
they dont. as doc_daneeka says having the communists in the funhouse will vary in timing from woman to woman, and so will *appear* synch sooner or later. Also: How long rag week lasts varies from days to aweek+, so you have fair chance getting a few women who have the painters in at the same time. Riding the crimson wave isn't quite the exact predictable cycle you might think. Though I heard that when on the pill, rebooting the ovarian operating system can become very regular", 'Periods deviate a lot during a month to month basis. They dont always have it the 15 to 22nd of every month etc. When you are dealing with something that lasts ~25% of the month. Its really not that hard for it to seemingly "sync" up. With that said, having multiple girls living together and having their periods align from time to time is barely a coincidence, its bound to happen. And you literally have one of four weeks to choose from so they could already have remotely the same cycles to begin with and that in itself is not even remotely impressive from a statistical level.
|
Why do they air the same TV show repeats when the show ran for years and has tons of episodes?
|
It'd have to do with higher and more consistent ratings for that TV station, more than likely. Speaking of The Simpsons, it's weird that the few times I've caught it on the local TV station instead of FXX, that they overdo focusing on airing the newer episodes, then when they go back to the better old seasons, they only air a handful of episodes from those seasons before mainly going back to the most recent seasons of Simpsons episodes. And it's widely known too that many Simpsons fans favor the older episodes and seasons, over the new episodes.

Why does your chest feel cold when you burp?
|
Just taking a guess here, but could you mean like right after you drink something cold? Burping is a way for your stomach to release gasses. Sometimes, these gasses can displace some of the liquid you've consumed and you feel a little bit of it rise up into your chest as the burp comes up. I've experienced that on occasion, but it's definitely less than half the time. Alternatively, you might be experiencing acid reflux, which is a more intense version of heartburn. I'm not a doctor, I'm just throwing ideas out.

The problem is how would you regulate a car so that it can still accelerate from 0-60mph in less than 8 seconds, yet have a maximum top speed of 75mph? You could easily just give the car an 85hp engine, and that would limit your top speed thanks to wind resistance, but do you really want to spend 15 seconds to get to 60mph? What if you're accelerating up a hill, against the wind, with 4 other people in the car? You'd never make it! The other option is to electronically limit the speed to 75mph. Companies already do this with speeds around 120-155mph, and it's easily removed by flashing the engine's computer with new software. The last option would be to mechanically limit the speed. Probably through a combination of lowering the redline and adjusting gear ratios. But now since you're limited by rpms, and your maximum speed is only slightly higher than the speed limit, you'll be driving around everywhere in top gear at nearly your engine's redline.Because any car capable of giving a safe, comfortable, efficient ride at 75 mph is also capable of an unsafe, uncomfortable, inefficient ride at 100. A car that had a maximum of 75 would be very unpleasant to drive at that speed, and would have very poor power and acceleration at 55.

How chemicals such as those used by exterminators can be classified as 'safe for humans' if they aren't tested on humans?
|
'safe' is a relative term. any substance, in substantial large enough quantities, [doses] or concentrations is lethal. simple example: the LD50 of *water* is 90g/kg. so there is such a thing as drinking too much water.

What is the Black Swan theory? Why is it important?
|
Winning the lottery is not a black swan. Someone always wins the lottery. It is known and expected that someone will win the lottery. Part of Nassim Taleb's work is to point out how unexpected events shape our world to a vast extent. For example our recent history is dominated by events leading from the 9/11 bombing which was unanticipated when he was elected.

How hard is it to assassinate the President of the United States?
|
You have been made moderator of /r/Pyongyang ! Seriously though, very difficult this day and age. All of the protective detail and secret service you see surrounding the president is only one small layer of defense. There are hundreds of people working behind the scenes everyday planning around his schedule. I'm not saying it isn't possible, but it would be far more difficult than you see on TV and in movies.Are you a cop? You have to tell me if you are!', "I've read that anyone can be assassinated by someone willing to sacrifice their life to do it. That's probably completely true. However, getting to the President in public would be difficult without a lot of planning. Since the President can only serve 8 years in office, and since many only serve 4 years, it seems like a lot of bother and loss for very little benefit.This thread is hilarious. Like no one is trying to get tracked down by the government right now.

Why do LED lights look jittery or like they're strobing when you look at them quickly?

Gonna jump off this because it's slightly related. Does anyone else get an odd feeling like they lack depth perception when looking at those blue Christmas LEDs?

Why are people in ebola-stricken nations so against accepting help from ebola workers/ relief efforts?
|
Because most people going to hospital will die and if one does not have Ebola already, one's chances of contracting are much higher in hospital, as happened with SARS in China.

why do apps require full permissions like making phone calls or reading sms etc?
|
yeah like the windows 8 CNN app. get a load of that shit. but alot of it is just that, unnecessary. if you want to downlaod it odds are your not really going to let permissions stop you . in some cases its good incase the dev wants to add something at a later date, but probably most of the time it's free data collection.

What exactly is radiation/ radiation poisoning and why aren't there ways to "flush" it out of your system?
|
The simplest answer is this: human beings haven't evolved to deal with any level higher than background radiation. Our cells can recover damaged DNA, but only a little. We weren't built to deal with high levels.There are animals that can. A bacteria called Strep. radiophilus can recover it's DNA at an almost constant rate, and is often found in abandoned radioactive storage tanks and, notably, in Chernobyl.

Non-smoker here, Why do smokers whack the shit out of their pack of cigarettes before opening it?
|
Where I'm from the ritual to a new pack is two steps. Step 1: Pack the squares nice and tight. Step 2: Assuming you have a the flip top box, take out a square, flip it upside down so the filter is on the bottom and put it back in the pack. That is your lucky cigarette, you smoke that last.

Why can't we breed bees on a massive scale and release them, to help with the dwindling bee population?
|
I'm sure you could get a lot more specific information from the folks over at /r/beekeeping on how to increase honeybee populations. But one thing to consider is that a lot of bee species that are important pollinators don't produce honey, at least not in commercial quantity. You would not want to crowd them out because of the need to preserve genetic diversity. So tread carefully.Local knowledge. In NZ we cant do that as the verroa mite kills any non kept hives within a year. The landscape and flora of nz is actually pretty perfect for bees but any wild hives, mostly from swarmed commercial sites, are dead very shortly after. We also have an issue with american foulbrood which is managable within controlled hives but obviously not in wild hivesDo you want killer bees?This is how you get killer bees.

shouldn't they just make phones tougher since most people end up buying an Otter Box or similar protective case anyway?
|
The Otter Box has its redeeming features but is a major marketing campaign. If your screen wants to get broken It'll get broke. Doesn't matter how much plastic you put around the phone. I am sure if all phones came with a permanent Otter Box then there would be some other 'sheild' device that would be marketed and sold to people.

If our blood travels through vessels in our bodies, how come we bleed no matter where the cut is located?
|
The reason the capillaries are close to the surface of your skin is because your body uses your blood to cool you off, by making the capillaries bigger. That's why you turn red when you are hot!

Why people still maintain that Obama is a Muslim, terrorist, not born in America, etc.
|
They're idiots. It's the same as any conspiracy theory, though: people will believe what they want to believe and no amount of evidence, no matter how ironclad, will convince them otherwise. There are people who seriously believe that NASA faked the moon landings, that the WTC was brought down in a controlled demolition, and that the earth is flat.bigotry + cognitive dissonance have allowed for absurd views to flourish within American society. Today, more than every, people with closed minded views can insulate their knowledge with little to no effort. Just flip on an overly biased news cast and soak in your ignoranceSo you mean those articles/YouTube videos stating he is the test tube baby of satan and is the antichrist are not true? Mind=blown.Former Obama voter voter here. There's no evidence the president was born outside the US but he is so out of touch with his people that the rumors stick. If he is a muslim I'm not sure why he'd need to hide it, most of the people who wouldn't vote for a muslim weren't going to vote for Obama anyway.

Why does light only penetrate 1000 meters of the ocean and not the entire ocean?
|
Easiest way to think about it. Let's say you are walking forward, through a forest and cannot turn left or right. But not just you, you and a million people. If the forest is only a few trees thick, then there's a high chance you can make it without hitting a tree. So a few trees thick forest maybe 800k would make it without hitting a tree. But add another row of trees. And another. And so on. Eventually the chances that even a single person could walk through the forest becomes 0 because there's too many trees in the way. Same goes for atoms and light. The light flies through and the atoms of water because there's mostly empty space. But once it goes through enough water the chances of light not hitting an atom becomes 0.

The Walton family is worth $150 billion. Why can't Walmart hire more employees at their stores?
|
The family has nothing to do with the way Wal-Mart is ran. Wal-Mart makes money by only paying minimum wage. The state indirectly subsidizes their employees through welfare. What Wal-Mart doesn't provide in living wages can be found through tax paying dollars. Essentially, Wal-Mart and tax payers foot the bill. There's no incentive for them to hire more employees, or invest in more workers. They're all easily replaceable, any kid in high school who wants a paycheck can get a job there.

Why is malt liquor significantly less expensive than beer?
|
Let's not ignore the very low marketing costs you're not going to see olde English buying a Super Bowl spot this year.
|
if we have enough grain and milk sitting in silos around the USA to feed the world why do we give farmers subsidizes to burn it instead of using that money to give it away?
|
Short answer is time and money. Milk goes bad relatively quickly, and it would be ludicrously expensive to ship it around the world. The people who don't get milk don't get it because *they can't afford it.* Yes, it would be nice if we could just ship it off to anyone who needs it, but who would foot the bill? Grain is the same, though time is less of an issue, as it doesn't spoil as fast as milk. Money still is the reason that we don't just give it away. It's cheaper to burn the excess than it would be to ship it around the world.

If you don't want people poaching elephants for ivory, why don't people just farm them?

Elephants are very big and very intelligent. There's no practical way to keep them inside a farm; they would just knock down something like a picket or chain-link fence.

How is it that we can take pictures of the Milky Way galaxy in the night sky when we are part of it?
|
The same way you can take pictures of the interior of your house from inside your house. These are pictures of our galaxy from our point within it. We're looking edge-on to the dense part of the galaxy, and that's what appears as the Milky Way in the sky.

How come _URL_0_ still has links to torrents from years ago despite having their servers seized?
|
Backups of TPB exist. Also, remember that Pirate Bay is basically a directory where one can download the torrent files, and they're not storing anything directly, so a backup of that directory could be relatively small when all things are considered.Files are not in one spot together, TPB is a place to tell you where they are

what percentage of calories do we actually take in? If I eat 2000 calories of food today, how much do I actually take in? I must poop some out?!
|
I didn't see a good answer in here that explained this well, but the listed calories on a food, are based off what humans can digest. The listed calories in a granola bar is the number of calories a human will get when it is digested. So if you eat 2000 calories, you get 2000 calories, and this varies only a tiny bit from person to person. Also, your metabolism isn't how much energy you get from food, metabolism is how much energy your organs use while resting.

How would raising minimum wage help the economy?
|
It could do what you say, but it could also increase profits by increasing volume of sales, even at the same price. It could also cause employers to hire more people to handle the greater demand. The most important thing increasing minimum wage would do is put to work money that is sitting around in rich companies' hoards. An economy is a living thing and you should not starve it of money.The idea is it would give citizens more disposable income, which in turn would help the economy. I am skeptical though, very ballsy move from Cameron, Osborne and co. Even the left are skeptical of it. Will be very interesting to see how it pans out!Repost removed.

How do you tell the difference between propaganda and news?
|
The line between them can be very blurry so don't feel bad about being able to tell the difference. If you're trying to learn about something read different sources, the differences between their coverage will help you discern their biases. You can also check on the Wikipedia entries for news agencies and reporters to get a sense of where they stand on issues generally.Love your description of online comments lol Anyway, as others have said all news sources have some sort of bias. The best route is to follow several sources from both the left and the right to get a better idea of the big picture.

Why do birth control pills need to be taken at the same time every day?
|
I haven't seen a really great ELI5 answer, so I'll give it a whack. Imagine you've been drinking amd you're now drunk. You know that feeling as you sober up? How it gradually happens over time. Imagine you wanted to stay buzzed for as long as possible, but you were only allowed a certain amount of drinks. Would you drink them all right away and get super-wasted? No. You'd have a couple now, wait until the buzz started to die, then have another to give it a kick. The idea with birth control pills is the same. Eventually your body processes it . Scientists designed the dose so that this happens after about 24 hours, simply because the 24 hour mark is really easy and really convenient. I would hate to take a pill every couple hours or even twice a day. Once a day is annoying, but manageable. Edit: Spelling", 'Progesterone only pills need to be taken at the same time. Combo pills with estrogen in them have some leeway.This is more important for progestogen-only pills, as they don't always inhibit ovulation, but prevent pregnancy but making the uterus unsuitable for implantation. If you don't take the pill soon enough, the hormone levels may drop to a point where implantation can take place. The more common combined oestrogen/progestogen pills inhibit ovulation, and you can often get away with missing a day here and there , as long as you have taken enough in your cycle to prevent ovulation.

Why can't you knee someone in the gut and have them throw up poop?

For the same reason you can't pump their arm up and down and jack their head up until their neck is like five feet long. Or, for the same reason you can't eat diamonds until you turn into one. Because that's not how it works.This question made me laugh really hard at work.. XD

Why do aircraft entertainment computers behave so slowly, in comparison to other electronics, like phones?

Likely because they're really old computers that haven't been upgraded because there's not much reason to upgrade them if they're not broken.

Because us white folks are like chameleons that can't control when our colors change. We turn blue when we're cold, red when hot, green when sick, etc. Being tan reduces those other colors.
|
Why do men seem to be more tolerant to colder temperatures and often times feel warmer to the touch than women?
|
There's some evidence that women have a 0.25 degree Celsius higher core temperature, as protection of foetus during pregnancy. This would lead to a greater difference between core temperature and periphery and therefore a perceptual difference of ambient temperature. In contrast women has a more even distribution of sub-cutaneous body fat. These two combined lead to women feeling cold more readily but actually able to deal with rather well . Women for example make excellent ultra distance cold water swimmers. ) and an extreme cold water swimmer.)", 'I often wondered this as well, my dad would get our woodstove red hot and my wife would be wrapped up in a blanket laying next to the stove and not one drop of sweat will occur but with me I cant even stand being in the room because it would be too damn hot.

Why does coffee smell so nice, but after drinking it, your breath smells terrible?
|
Well, the dry mouth bit is true its known to cause bacteria and tooth decay but I feel like thats more of a long term thing and explains constant bad breath, but not so much the immediate bad breath after a cup of coffee. I think personally the main reason coffee makes your breath smell bad is cause of the milk/cream that is in it. For some reason, dairy makes your breath smell bad and it can be very noticeable, to you or people around you. I'm curious if you would still think your breath smells bad if you drink your coffee black.

Why don't we have a "microwave" equivalent of a freezer that could take a beer, or whatever, down to zero degrees in 60-90 seconds?
|
Here's what I do to chill beer quickly. It doesn't take a minute but it works way faster than just putting it in the freezer or a cooler with ice. You soak a paper towel and wrap the bottle in it. Throw it in the freezer and in 10 minutes you got an ice cold beer. I've been using this trick for years.

Why don't we have $25 bills?
|
Australia got their coins right. 5cent - Smallest silver coin the size of a dime with a echidna on it.10cent - Slightly larger than 5c, this silver coin represents a Lyrebird .20cent - Slightly larger than 10c, 20c is a silver coin just larger than the US quarter with a awesome platypus.50cent - largest of all Aus coins, the 50c is 12 sided and shows the Aus coat of arms . 1 dollar - The $1 coin is similar to the 20c except for the gold colouring and portrait of 5 Kangaroo's.2 dollar - A small gold coin roughly the size of the 10c coin. This coin is thicker and features an Aboriginal Elder. We also minted 1c & 2c coins however they were discontinued due to inflation over the years. The quarter works perfectly well except for the large gap between 25c & $1 and I would discontinue the penny asap!

Would it be possible for a colo(u)r to have a negative hue?
|
It's a fair question. Typically no, there's no negative hue; it ranges from 0 to 359. But when they were doing early experiments with getting TV screen and monitor colors right they found out that there are colors we can see in the real world that monitors can't recreate. Typically screens like the one you're looking at right now create colors by adding different hues of lights together - a lot of closely packed pixels combine to make an overall hue. Naturally this is called an additive process. Physically mixing colors, like with paints, you'll get a different color, even if you mix the exact same red, green, yellow, or blue that you did with lights. This is because paints, or physical pigments, only reflect certain frequencies of light; they don't emit them. Mixing various colors this way ends up subtracting the hues, or colors. So when they first started calibrating the colors in the color TV system they learned subtractive mixing of colors could give you hues that the additive process can't, and never will. They did figure out a way to quantify the difference though. They got two shades, one from adding colors and one from subtracting, as close as they could visually be. Then they added colored light to the physical pigments until they got a match. This was then found to be what needed to be subtracted from a screen to match the real world. So in a way your question is spot on. Edit for spelling

why airplanes must land with a certain amount of fuel
|
Many airplanes have landing gear that isn't rated to withstand the shock of landing fully loaded - rolling down the runway is fine, but absorbing the impact of landing puts more strain on them than just supporting the plane's weight. I recall reading that this was a particular problem with the B-24 bomber of WWII - as a bomber, it was designed with the assumption that its payload would be dropped before landing, but when they were used as cargo planes this obviously wasn't the case, and so they were susceptible to landing gear failures on landing. Another factor is that, if a rough landing is expected for any reason, the pilot may jettison excess fuel, so as to reduce the fire/explosion risk, as well as putting less strain on the landing gear.

direction", etc. He lives far away from you, so you can't demonstrate or direct him. How can you teach Tom what "turn left" means, using what he already knows? The instructions "turn right" are a _function_ that Tom knows how to do. We can teach Tom to use "turn right" to accomplish a new function: "turn left" = "turn right" 3 times. Programming is like teaching computers, like Tom, how to use functions they already have to do something new!I go to law school. Law school is where people go who never knew what they wanted to be when they grew up. At law school, they teach me all the different ways that people can fight with each other without using their fists or guns, and they teach me how to be as good at it as possible so that other people will pay me to fight *for* them one day. Being a lawyer is a good job because a lot of lawyers make a lot of money and sometimes they get to help people who really needed it.

What is libertarianism? ELI5
|
Libertarians are people that usually think that people should be allowed to do whatever they want as long as it doesn't hurt anyone else. Not all libertarians think the exact same things, though. Some think that the government should only make laws about a few things like protecting people from bad people and making sure that people fulfill their contracts . Right now, the government also does things like helping poor people and building schools, but some libertarians think that regular people and NOT the government should do those things. There are many other details, but that's the general idea of it.

Hey LI5, what's the difference between Sunni and Shiite Muslims?
|
The Sunni branch believes that the first four caliphs--Mohammed's successors--rightfully took his place as the leaders of Muslims. They recognize the heirs of the four caliphs as legitimate religious leaders. These heirs ruled continuously in the Arab world until the break-up of the Ottoman Empire following the end of the First World War. Shiites believe that only the heirs of the fourth caliph, Ali, are the legitimate successors of Mohammed.

Why is gold valuable?
|
Gold is rare, but not so rare that it's impossible to find, like rare earth metals; it is also a distinct color, like copper, but harder to find; it can be divided into tiny bits or put together into bigger bits without fatiguing; and it doesn't tarnish . It's heavy so it's easier to tell if it is genuine. It's kinda pretty. Those are all reasons gold became valuable. Now it's used for its conductive properties in computer parts. But mostly, it's valuable because everyone agrees it's valuable. See [rai stones]

E=mc²: What does the speed of light have to do with anything?
|
I'm not going into anything here. I just remember not being able to put any mental use to work on that theory.. just the theory of it, I'm le suck at maths. But I still like to examine scientific theories and think about the universe. I found a BBC documentary - a two parter - called Everything & Nothing. Its starting out from a nice angle - explaining the process in which we were able to determine the size of our planets, galaxies and finally look further into the universe. And this is the part where the speed of light becomes very relevant all of the sudden. tl'dr found a nice and easy documentary on it _URL_2_", 'There are some smart 5-year-olds in this post. I think I need an "Explain like I'm an Embryo".

the Crips and the Bloods.
|
Once upon a time in Los Angeles, there was a group of black men that wanted to protect their neighborhood from other gangs. They called themselves the Crips. Over time, the Crips grew large and forged alliances with other neighborhood gangs. However, in this growth, there was some disagreement. As the Crips were themselves a gang, this disagreement grew violent. Eventually, one of the allied gangs left the alliance and began to call themselves the Bloods. The fight between the gangs raged on, as the Bloods had taken a lot of territory and drug business from the Crips. That's really it.These are two huge street gangs that started in LA. They kill people and commit other crimes.

How can the Hubble take brilliant images of galaxies millions of light-years away, but no clear images of Pluto exist?
|
Pluto is really small. From the earth, its diameter is at most about 0.115 arc seconds. By comparison, the moon is at most 2046 arc seconds and Jupiter is at most about 50 arc seconds. The Hubble can resolve about 0.04 arc seconds, which is not much in relation to Pluto. [This is about all you can get] with the HST. The HST can do a good job with Jupiter, but Pluto is 1/500 its angular diameter. It's ridiculous how small Pluto appears from Earth. Almost everything is bigger, including moons of Mars, Jupiter, Saturn, and even Neptune.

how the moon affects tides
|
Imagine the earth and the moon are like a fat person and his kid respectively. Gravity works by the fatty pulling the kid toward him, but the kid is being spun so he never actually gets any closer. Now all objects exert some degree of gravity. The kid, being much smaller than the fatty can pull as well, but not as strongly because he's small and young. But still, the kid tries to pull whatever it can towards it. The clothes on the fat person are like the oceans of the earth. They're on the earth but they're loose and not really attached. So the kid grabs onto the clothes and pulls them towards him, causing a bulge. This bulge is essentially the tides we get every day.

why does it hurt when you get hit in the testicles?
|
Your body makes you feel pain so that you avoid damagin parts of your body. When you twist your ankle, your body makes it painful to walk on it so that you don't do further damage by just walking on it normally. Your body makes you feel more pain in areas that are either very easy to damage, or are super important. That's why a punch in the ear hurts more than a punch in the arm. Your ears are super important, so your body sends you lots of pain when they get damaged to make sure that you don't let anything happen to them. Your testicles are both easily damaged, and very important, so your body sends lots and lots of pain when they get hurt to make really really sure that you know not to let whatever hurt them happen again.One of the main focuses of all life as we know it is to reproduce, and your testicular health is vital to your ability to do this. If you could knock them around with little hurt, there is a high chance you will lose full reproductive potential. So, through weeding out people who were literally "numb nuts" over time, the evolutionary process has left us with people who now guard their groins from harm due to the increased sensitivity to pain in them. Due to this, these people are more likely to pass on this trait as they are more likely to have fully functioning testicles

Why doesn't the Moon get sucked in by the Earth's gravity... or fly off into space?
|
technically we ARE losing our moon. Over time, it will be gone. This is happening very very very very slowly though. So don't sweat it. > Yet celestial bodies maintain that delicate balance for millions of revolutions. How?? Look at it this way It didn't start out perfect. You had a bunch of gas that gravity pulled together into a star. You had a bunch of star dust hanging out as well. Gravity pulls this stuff together into a planet. If this matter wasn't in a solid orbit it would be lost. Over time gravity collects all the matter into the planets we have now. Gravity also pulls this matter into a mostly spherical shape. Now you have planets! and any other matter that didn't have a perfect orbit either was lost, got sucked into the sun, or was pulled into another planet. There are a few exceptions to this like our asteroid belt, comets, and outer clouds. But basically, our orbits are a result of time and gravity. You are only witnessing the end result, not the chaos that took place before hand.

How was the first computer program made?
|
You can compile a program into machine code by hand, it's just a lot more tedious.Take a look at this book: [Code] The book starts off with a switch and builds a whole computer from there1, 0, 0, 0, 1, 1, 0, 1, 1, .Simple answer: by flipping switches. It's entirely possible to enter data into a computer's memory by using switches to represent 1's and 0's.

Why water evaporates even though the temperature doesn't exceed the boiling point.
|
Taking a shot at a good old-fashioned ELI5 analogy. Sorry if it's a bit low-brow. Pliskin01's response is right on, just more technical. Instead of a pot of water, you have a bunch of people with . . . hmm . . . hang gliders standing on the edge of a cliff. Big plateau. And there are some people flying next to the cliff. People standing are the liquid, people flying are the gas. So, somebody standing with a hang glider needs a certain amount of room. Someone flying obviously needs lots more. But if the people on the edge of the cliff see that there's enough room for them to jump off and start flying, a couple of them are gonna do that. That's evaporation. As long as there's enough room in the air, some people will jump off and start flying . The people not on the edge won't notice, and will just keep milling around in the crowded space. Boiling is when it gets so hot that no matter where they are on the plateau, people just bolt for the edge and jump off. And no matter how crowded it is in the air already, it's so bad on the plateau that they're all jumping off. So, ass Pliskin01 said, evaporating is a gradual process to reach equilibrium, whereas boiling uses energy to force the water into a gaseous state.

Why America never switched to the metric system (or SI), whereas most other countries did.
|
i have no idea but i think that the reason is most likely cost, both financial and mental. it will cost billions of dollars to change everything from one system to the next. road signs, maps, literature, everything will need to be edited. conversion systems will have to be designed and maintained for decades for people who are already too used to the imperial system. as for the mental aspect, people just don't like to change. i think it's just that simple. it'll be like when scientists took away pluto's planet classification, except this time it'll be with something that actually matters. i'm sure others have a better explanation of this, but i'm too lazy to google anything.

What string theory is...
|
We know everyday objects around us are made up of atoms, which in turn are made up of proton, neutrons, and electrons. Protons and neutrons are in turn made up of even smaller particles called quarks, on the scale of electrons. As far as we know, particles on this scale cannot be further subdivided. So what do they actually look like? They're often drawn as circles, but there's no reason to think they'd be spheres. After all, they could just as easily be cubes or pyramids. One possibility is they have no size at all, and they just exist through the forces they convey on other particles. String theory proposes that they are in fact made up of little loops, called strings. The strings can vibrate in different ways, and the way in which they vibrate determines what properties they have, and thus what particle they are. Again, from pure observation, we have no reason to think these particles are shaped like strings over cubes. However, physicists were able to do theoretical calculations assuming that matter was made of strings, and they found that this would solve many of the unresolved problems in physics, like how a black hole works or how gravity affects these really small particles. As they continued these calculations, they also came to some unexpected conclusions, such as that there would have to be 11-dimensions for the hypothesis to work.This sets a really good base to understanding it _URL_0_Well, im still a little confused but the lava lamp was probably the most helpful. Now if only I knew what quantum mechanics were I could start my paper!

How does healthcare work in the US?
|
I know it sounds really ignorant, so the bill that Obama passed recently that was quite contraversial, what was that all about? By the sounds of it to me, health care has reached the point where it is almost unattainable for the poor and middle class because of so many insurance rules and over charging by the hospitals and doctors. Why has nothing been done about it? I live in a country where health is available to almost all people, and insurance companies usually don't have the power to deny you a claim, or if they did, we could easily fight against the decision.First you call a doctor and you make an appointment for a few days later. You go there and a 15 minute visit costs about $200. Insurance only covers a small portion. He/she writes you a perscription for a $100 medication with about 10 or 15 pills. You pay for your perscription and find out insurance "saved" you $8 on your perscription. At the end of the month you pay about $100 to $200 a month for insurance whether you used it or not.

Why does cold water taste so much better than room temperature or warm water?
|
It's cultural. I spent part of this summer in Malaysia, and ~~everybody I met there drinks~~ I was always served hot water .I'm not going to try to explain it scientifically, but you taste things that are cold less. Heat brings out the flavor in food and drink. Maybe it has something to do with vapors and particles, but like I said, I'm not going to try to explain it scientifically, more like if you were five.When it comes to water, the less "flavors" the better. Edit:Unless your drinking pure fresh water, in which case it would taste amazing no matter the temperature.I used to love cold water, but since living in hotter countries, I've learned to prefer room temp water, it gets into the system quicker and is easier to drink in larger quantities. Now I can't stand water that's too cold.My best guess is that cold water disables your taste buds to a degree. I know that is one of the benefits of soft serve ice cream rather then normal ice cream. Your taste buds are actually heat sensitive. This is only a slightly educated guess, but I would say that this is probably pretty close to the correct answer', "It's an evolutionary trait. Cold clear water is most likely from a stream, and safe to drink. While warm water is likely from a standing pool and stagnant. It's the same reason hot food is so much more enjoyable than lukewarm food.

EILI5: The difference between marxism, trotskyism, leninism, stalinism and maoism
|
Just a note -- calling the Kim regime a 'Stalinist' one is a deeply divisive issue within the Korea scholarship community. I think that most scholars have agreed that Kim Jong Il, unlike his father, has strayed from most traditional definitions of 'Stalinism.' In fact, some scholars have gone as far as to claim that KJI is not far left, but rather far right. B.R. Meyers has one of the better explanations of regime ideology, if you're interested. [Link: Foreign Policy]", 'Any time a person does something different, they get *-ism* added to the end of their name. Man has a label fetishThis question would probably be better suited for /r/AskHistorians or /r/AskSocialScience.

Why warm water freezes/cools faster than colder water.
|
I've worked in the ice rink business for several years, and I can tell you that hot water does appear to freeze at the same rate as colder water, we use hot water when we resurface because it makes the ice smoother, it does this by melting and refreezing, if the hot water took too long to freeze we wouldn't use it, btw, we use 140 degree water and the ice surface is usually about 22 degrees.
