Why are some of my dino nuggets ice cold and the others lava hot, even when I place them in a circle?	[ "A microwave produces [standing microwave waves](_URL_0_) inside it to vibrate certain molecules in food to heat it up.\n\nThe issue is that the wavelength of the microwave is about 12 cm long. Due to the nature of the standing wave, this means that there are spots where the waves cancel out every 6 cm (nodes).\n\n...
why is it that when food is too hot to touch it doesn't necessarily burn your mouth when eating?	[ "Because the inside of your mouth is already around 37C and coated in slimy film, where as your hands are dry and have a surface temperature relative to the air temperature. \n\nIf you dipped your hands in say..slime, they could also pick up hotter objects. Your hands and other sensory organs are wired to tell you ...
why are animated gifs substantially larger than mp4 videos?	[ "An animated GIF is a series of images stuck after each other, like an old movie roll. So you have all the data of all the frames: Frame + Frame + Frame + Frame + [....] + Frame.\n\nAn MP4 video is a repeat of a full frame image followed by a series of incremental frames which show the differences with the full ima...
Why do people instantly grab/press a body part which just got hit/injured?	[ "I would assume people do this to prevent further damage to that body part. For example, if you are in a fight with someone and they punch you in the left arm, you would cover it to try to block more damage from happening. It could also be for applying pressure on a wound to lessen the bleeding." ]
Why are some websites updated with "© 2016" at the bottom while others may say "© 2012" or whatever year, when clearly they're still copyrighted?	[ "The copyright date establishes the beginning of the copyright (this is very simplified, but go with it).

Why do businesses seem to be stingy with ten-dollar bills?	[ "Often they have few if any to give. The thing is, fives are more versatile since they can break tens or twenties, but tens can only break twenties or higher. Higher than twenties the next up is fifty or a hundred, so youre better off breaking with twenties and fives (2 20s and 2 5s = 50. 5 20s = 100). Considering ...
What happens to the animals killed during crop harvesting?	[ "A farmer friend of mine said, yes they do occassionally clog up the works (bigger animals) but for the most part they end up in the harvester, and caught by various filters, and by the sorting devices later. Larger animals, once freed (they are obv dead), are often tossed off to the side for the predators/scavenge...
Why is disinfecting wounds painful?	[ "There's two main reasons. First, the wound is sensitive, as that part of the body has been damaged and is screaming at your brain to start taking damage control steps. Putting anything in an open wound is going to hurt some. Second, the things we use to disinfect typically do that by killing biological material,...
Why not sue the FDA when a product hurts someone? Why is it that the company that made the product is the one to be blamed when they assumed everything was all good and well after approval by the FDA?	[ "Oftentimes, the FDA was also a victim of fraud, specifically of fraudulent submission of bad safety research. Why blame the FDA when the company is 100% at fault?", "You cannot sue the United States without its consent. Congress has given this consent in some cases, where a government employee was negligent in...
When there is a catastrophic injury to a person's head, why is there a delay before blood starts pouring out? [NSFL]	[ "It isn't just the head but most flesh that reacts this way. An injury usually happens when force is applied to the flesh and this tends to compress it before tearing it, which pushes blood out of it into the surrounding tissues. Imagine if you forced a rod through a sponge; it would tend to squeeze the water out o...
How did (western?) musicians decide upon 7 musical notes?	[ "The seven-note scale is called the 'diatonic' scale (which, according to Wikipedia, means '[progressing] through tones' -- TIL). Musical archaeologists have found some evidence that it's been in use for many thousands of years, but nobody's quite sure exactly when it started.\n\nThere are all sorts of special reas...
Why most high caliber Sniper rifles are shown as having low capacity magazines?	[ "Because if you had a 30 round magazine of 50bmg, it would be 2 ft long, weigh 10 pounds.", "[.50bmg is a BIG bullet.](_URL_0_) This means it takes up more room in magazines and is heavier to carry around. \n\nThe most famous gun to use that round, the Barretta M82 (better known as the Barrett .50) is for the US ...
How are exchange rates decided? Who decides the actual numeric value of one currency in another?	[ "In the modern economy, most exchange rates are determined essentially by supply and demand. For example, if you are American you are paid in dollars, but need Euros to buy goods produced in Germany. When you want to buy a German good, you are \"demanding\" Euros and \"supplying\" dollars so the value of Euros incr...
Cold temperatures wake us up while hot make us tired, is this purely a matter of comfortability or is there something happening to our bodies?	[ "[There was a study done](_URL_0_) and it says the optimal sleep temperature is between 60-68 degrees farenheit. Too warm or too cold and you can become restless. It's interesting that warm temperatures make you tired, the opposite rings true for myself.", "When you're cold, your body's response is to move to war...
Fossil fuel subsidies	[ "I do not know all of them. All companies try to get favorable tax policies so they maximize their profit.\n\nCompanies buy equipment which will last for years but eventually become junk. This includes cars, trucks and actually everything else. So the value of the property declines over years. They argue with tax m...
What do they mean when they say the mass of the atmosphere of Pluto has decreased by a factor of 2 in two years?	[ "Uhhhh, Pluto is heading into it's hundred year 'winter' season. The atmosphere is freezing to the planet as ice. It's a 'dwarf' planet equivalent of a comet (sorta). Everyone saying it's lack of gravity is missing the fact that that process takes eons, not two years.", "Pluto was recently at its closest appro...
why wired data transfer is faster than wireless.	[ "I think it's mostly because wireless transfer is more prone to interference - it's very difficult to corrupt data that's being sent over a wire, but it's very easy to corrupt it (even unintentionally) if it's sent through the air. Particularly if there's any sort of obstacle between the transmitter and the receive...
If you were sucked out of a spaceship, how would you die and how long would it take? Would it be the cold to kill you first, the lack of oxygen, or the lack of pressure?	[ "Lack of oxygen would do you in long before anything else.\n\nThe pressure differential would cause a lot of pain, but wouldn't be immediately fatal, and the cold would take hours to do any real damage." ]
Why are search boxes in many websites so seemingly innefective, while googling the same thing almost always gives me what I was looking for?	[ "Google has been optimizing their algorithm for a long time.

Because Google is popular, a lot of people have used it, and so they hav...
Why are baby animals so cute? Is there a genetic advantage to this?	[ "There is some belief that traits we identify with 'cuteness' are traits possessed by immature animals, and as such there's a protective/friendly hardwiring in the brain. The advantage would presumably be that immature animals are less capable of caring for themselves, and therefore those that are cared for by adul...
What is ASMR? Can anyone describe what it’s like?	[ "It stands for Autonomous Sensory Meridian Response. Basically, it's a physical/physiological reaction to certain sounds. These trigger a tingly sensation esp on the spine and head. It can also be used as a relaxation technique. Others have a sexual response to it.\n\nSo it's kind of the reverse of nails on a chalk...
how come all my friends' houses and clothes have a distinct, separate smell?	[ "Ah, that \"Jeff smell\". This has remarkably little to do with showering routine and cleaning products, and almost everything to do with your personal sweat.

How is it I can spend 3 hours laying still in bed not sleeping, then doze off repeatedly in the middle of driving the next morning?	[ "Are you saying that you actually doze off while driving? Repeatedly?\n\nThis is not normal and is a grave concern to me. I have never dozed off while driving. You should not be risking your life and that of other drivers that way. I'm frankly totally shocked. If something like that happened to me, I think I woul...
Why are we charged 9/10th of a penny with gasoline?	[ "In addition to the other posts, another reason is that gasoline profit margins are extremely tight but high volume, and it adds up. In 2014, it ended up being an extra $1.2 billion in revenue. via [source](_URL_0_) (which has a nice history as well, if you're curious)" ]
If I let two chess engines play each other 100 times, how do they play 100 different games if there must be one optimal game?	[ "There is a field of Computer Science called \"Computation Theory\", which is adjacent to AI. \n\nWith our current computation power, we aren't even able to solve a single chess opening (a game after some set opening moves are played), let alone the game itself, so while working with Computation Theory has advanced...
How does a cars speedometer know not to increase when a cars tires are spinning?	[ "It does not know. It assumes the tires are in proper contact with the ground, and when they are not, it gives an incorrect reading.\n\nFuture speedometers may be corrected using GPS, but that generally is not done today.", "I haven't worked on a newer car, but on older cars the speedometer is driven by a cable/g...
why it takes so many years for a county like Iran to build a nuclear weapon when the technology has been around for over 60 years?	[ "eli5: imagine you are at school and little billy has made a paper crane. his friend johnny also knows how to make a paper crane, and they make lots of paper cranes together. they didn't tell each other how, and they didn't learn from a book - they just kind of figured it out one day, trial and error.\n\nso now you...
How do burning arrows stay lit after the immense acceleration they experience being shot from a bow?	[ "Depending on the fuel used, it can be almost comically challenging to put it out. If you've ever dealt with a gas fire, you'll know what I mean. I'd wager they were using coal-tar or peat or natural gas of some sort -- though I'm a little out of my depth here." ]
How is the US allowed to just raise tarrifs when laws that have minors effects on trade have to go all the way through the WTO?	[ "The premise of your question is mistaken. The European Union has initiated a WTO case against the US over these tariffs." ]
Why do we use the base 10 system, and what are its benefits over other mathematical systems?	[ "no benefit, other than a convenient correlation with the number of fingers.\n\nthere are better systems that work better with the base 2 of computers and which have more easily divisable fractions. Base 16 would probably be an ideal candidate for both things.", "tl;dr: The decimal (base 10) system came to be ba...
how does hand sanitizer make your hands clean when you don't use anything to wipe the dirt off them?	[ "Hand sanitizer is not the same as hand cleaner. Its only function is to kill the micro-organisms on your hands. \n\nThere are certain gels called hand cleaners that work like a pencil eraser though. Those ones do actually clean your hands by trapping dirt and then flaking away as you rub them together.", "Well...
The crucial difference between operating systems (Windows, Mac OS, Linux etc...)	[ "Windows - > Expensive. Sort of easy interface with many \"advanced mode\" options. Closed source.

If someone gets arrested but is later found innocent, why does their arrest and initial charge remain on the NCIC's database?	[ "if there is no record that it happened then the government might think they forgot to arrest you or something. if you are found innocent you can remove it from your publicly viewable record.", "Most people will never see a complete report from someone's criminal history on NCIC. I use it as part of my job, and s...
How is it so difficult for video game publishers to detect cheating on PC?	[ "The fundamental problem is that the user has physical control over their own PC and the only information the game manufacturer gets is whatever their PC sends.\n\n > Doesn't their code have digital signatures?\n\nSure, and those can always be defeated someone with enough time and perseverance. Let's say the code ...
why certain surgeries require months of recovery time	[ "Well, it really depends on the part of the body being operated on. Different types of cells in different areas of the body replicate and replace at different rates. A neuron, for example, can take as long as 7 years to replace itself (which is why brain damage is such a nasty injury). Shoulder muscles can take mon...
Why do Japanese albums often contain bonus tracks not available elsewhere?	[ "There is complex and lengthy process to be allow to sell albums in Japan.\n\nThis leads to the fact that most of the time, album are release in Japan later than in other country.\n\nTo make sure people wait for the japanese release and don't just buy stuff abroad through internet, companies put exclusives bonus tr...
How are Rocks Formed	[ "When lava comes out of a volcano and cools off, it creates rock and that's called igneous rock (granite, obsidian, pumice). \n\n\nWhen igneous rock has been ground down and combined with with other material and water (like at the bottom of a lake or river), it sticks together and dries to make sedimentary rock (Sh...
Where does the term "the birds and the bees" to explain sex-talk came from?	[ "Birds and bees are good animals to use to discuss sexual reproduction with children without the need to talk about sex itself, using processes that children are likely familiar with.\n\nBirds lay eggs, which is similar to female ovulation. Bees deposit pollen into flowers, which is similar to male fertilis...
how do we know when our sun will go supernova?	[ "Our sun will not go supernova, and when our sun begins to die, it will go big and red.\n\nWe know this due to calculations that we do and observations.", "Our sun doesn't have enough mass for that.

Why do people give Al Gore credit for inventing the internet?	[ "They really don't. Some people say it as a joke, but that's it. [The snopes article has more information.](_URL_0_) You only need to read the first three paragraphs.", "This is more of a question of older Republican/conservative wordplay than anything else. Al Gore never said he had a hand in inventing the inter...
What exactly is happening when a black hole 'burps'?	[ "Around some black holes an accretion disk is formed.

what prevents dangerous mold from growing on cheese during the aging process?	[ "During normal aging-for-production, no mold will infect the cheese by itself. Shortly after \"creating\" what will become a cheese, it is separated from the surroundings by rubbing a special, very salty solution on its surface frequently (depends on the cheese how often). Cheese which isn't treated that way freque...
Why did the DEA decide to make CBD a schedule 1 narcotic?	[ "Because there is a long history of pharmaceutical companies lobbying to have anything that might take some of their money made illegal.

Who decided that we need exactly 12 years of grade school? Seems like kind of a random number to me.	[ "OP, /u/Teekno has some decent points, but his information is a bit inaccurate.

What, exactly is happening when I have diarrhea? Why is liquid falling from my butt?	[ "Whenever you eat food or drink water, your stomach begins to digest it and produces a liquidy substance called \"chyme\" which is essentially just partially digested food.

The U.S. President just said in his Weekly Address that the U.S. Air Force is the smallest it's been since 1947. How is that possible since the AF was established in 1947?	[ "Because the US Army Air Force transferred all assets and personnel to the US Air force upon its creation and in 1947 they had a lot of assets having just finished fighting WW2. More pertinent should be just how stupid that talking point is in terms effectiveness. If you only measure the effectiveness of any bran...
What are crazy long math equations used for, and what do they solve?	[ "Not everything that is worth doing can be described simply.

How much executive power does the PotUS have to launch nuclear weapons?	[ "All of it. \n\nThey do not have to get the permission of anyone to launch a nuke as they are the commander in of the military and are the singular authority over them.

Is water truly a renewable resource? I know we have a lot of it, but could we ever run out?	[ "Water is absolutely a renewable resource. That is to say, (very very nearly) the same amount of water is \"on\" planet earth constantly.

Why is Nickelback so hated?	[ "The main thing for me is how ridiculously similar their songs are.

why are scientists trying to clone a wooly mammoth using ancient DNA when they could be cloning endangered animal species, such as the white rhino, whose DNA we can still collect?	[ "As has already been said, there are research efforts focused on both.

How does Windows estimate file transfer times, and why are they hardly ever accurate?	[ "Simply put it estimates the transfer time by the total size (to estimate the time it takes for the physical moving) and total number of files (to estimate the time it takes to \"make\" those new files, in newer versions at least) you need to transfer.

Why is network speed measured in bits but storage size in bytes?	[ "Because when information is transmitted over the network, extra bits are added to tell routers where each packet needs to go, and to add coding that will help minimize transmission errors.
