If Rainbows are caused by how human's eyes perceive light, why are rainbows visible on video? | Rainbows are a very real consequence of the interaction of light and water in the air. That is to say, they represent a physical reality. However, *vision* is the human perception of light, so a rainbow is only seen by the interaction of the actual physical phenomenon, and your perception of its results. Is that what y... |

Why can we cross our eyes inwards but not out? | Because there's no need for it. Some animal species use their eyes separately . Humans don't. We look at the same thing with both eyes, and we use the slightly different view from both eyes to recreate 3D and estimate distances. Now, when we look at the same thing with both eyes, sometimes we need to cross our eyes inw... |
How does increasing torque increases traction? | You're right! If a car has more power, thus more torque at a given RPM, then the only thing that will give it more traction is the design of the tire tread or an increase of the weight of the car.

Why can we kinda sense people watching us? | You cant, but heres a scenario: You are riding on the bus when you get this feeling that you are being watched from behind. You turn your head around sharply to try and catch them in the act, and you see like four or five people looking right at you! What actually happened was: nobody was watching you before you turned... |
Whats the difference between turbocharging and supercharging your car? | Engines produce power by mixing air & fuel and then burning them. On a *naturally aspirated* engine, there's a limit to how much air it can suck in, meaning there's a limit to how much fuel you can burn, limiting power output. Super- & turbo-chargers are devices that force more air into the engine, allowing you to burn... |
What is the aspect ratio of real life? Is it widescreen? Or a perfect square? | Hold your hands out to the side of your face on each side, staring straight forward. move them farther back until the disapper and make a mental note of where they are. do the same above and below.

What does steam really do when it verifies the game cache? | Cache is just a word for somewhere pre-computed/pre-downloaded data is stored. I don't know which it is in your situation, so i will just say generally. When you play something that requires graphics models that are not currently on your computer, it will download them. Instead of downloading it every time it will save... |
how can you reattach a finger (or any body part) after an amputation? I don't get how the parts would reconnect after it's been severed, especially the bone. | Broken bones will heal together if you put them close. Think about it this way--if your bone is totally broken but not amputated, you can still put them back together and they'll heal. The damaged tissues like each other and release chemicals that say "hey let's bond." The microsurgery is how they "sew" tiny arteries a... |
Burning up when re-entering earths atmosphere, would it be okay if rockets, shuttles or whatever it is nowdays just did it slowly? | Yes. A spacecraft in low earth orbit is going at 17500mph. If it fired its rockets to slow down to say 100mph its orbit would quickly deteriorate and it would gently reenter the atmosphere However that would take as mush fuel as it did to get up there in the first place, excpet you would now need even more fuel to laun... |
Why do characters in movies always take off their bullet proof vests right after being shot? | From a movie sense, to show the audience that the vest stopped the bullet, and that the shootout is over. From a realistic perspective, bulletproof vests are really only designed to take one bullet. Once they take one bullet, their ability to stop more bullets drops off drastically. After the first one, you'd probably ... |

The amp makes the electr... |
Why do laptop screen colors change at different viewing angles, but phone colors remain the same no matter what angle, and what causes this effect? | It comes down to the displays used in each. Most desktop and laptop monitors use TN panels , they are cheap and fast but that is at the tradeoff of colour accuracy and viewing angles. IPS panels are slow but have more accurate colour and can be viewed from near any angle without distortion. What actually causes the dis... |
Why can't we remember the first years of our life? | I can't remember the first few years because there was no "I" then. It developed laterForgive me for the repost :) - maybe you'll find it interesting: I think this is the reason; Our memories are not like copies of things. We don't remember visuals like a camera takes photos or film, and we don't remember sound like it... |
Why do plants, which rely on the sun, burn in the sun? At what point does this occur? | Why do humans, who rely on heat, burn with too much heat? Obviously everything has tolerances for heat that it can and can't take. Exact tolerances depend on the species and even the breed. For example, huskies can't really handle the tropics, and chihuahuas can't really handle Alaska. The burning point of plants depen... |
When choosing from a menu, why am I "in the mood" for a certain type of food. | Nutrient cravings combined with enjoyment/emotional attachment to various foodsBecause your body requires many different kinds of nutrients to run smoothly, and no single food has all of them.

What is the purpose of 'Press any button to start' screens in video games? | This is legacy from the old days. A computer game would take a long time to load. LONG time. This is because instead of being on a CD-Rom or harddrive, we were loading them via a tape drive. Think cassette tape. A load time of 10, 20, 30 minutes was not unheard of. While you are waiting, you would walk away, get some c... |
Why are the bottom of plastic bottles a funny shape and why can't it just have a flat bottom (eg. Mountain Dew, Pepsi ect)? | I am old enough to remember when plastic soda bottles did have flat bottoms -- it was a separate piece, like a cap. The part containing the liquid was round, like the bottom of a test tube, and that sat inside a glued-on black plastic piece. Without that piece, the bottle would not be able to stand up. Then someone fig... |

and12] What is a game engine and what does it control? | One way to look at a game engine is as a lego set. It basically is the platform in which you construct the game -- the levels, the models, etc. If you want to take it a step further, old lego sets had simple blocks. You very much had to use your imagination to fill in the gaps of where perception meets reality. In much... |
How come there is no better medications for simple sicknesses like cold and cough other than minor relief meds? | Colds and flus are caused by viruses. We have antibiotics that are used to kill bacteria, but viruses are much harder to kill without also killing healthy cells. We can give vaccines that help prepare the body's acquired immune system to target specific viruses, but once your cells are infected with a virus usually the... |
How do we calculate the fat and protein percentage in meat? | As far as I understand it, as a 5 year old myself, it's based on a calorimeter reading, which is essentially destroying an identical food in a controlled chamber to evaluate its energy potential based on heat changes, combined with density and weight values already known. So, for example, a 12 oz sirloin can be calcula... |
Why does it say to not exceed 2 gummy vitamins a day? What would happen if I were to eat the entire jar? | It is possible to overdose on fat-soluble vitamins.

What are the effects of an explosion's shock wave on the human body? | The main dangers of a shockwave is that it can burst blood vessels in your lungs and you can drown. This depends on the size of the explosion and the medium. Shockwaves through air have to be very powerful, to the point that it's the blast you care about and not the shockwave. If a shockwave traveling through water hit... |
Why do so many songs have the phrase 'California dreaming' in it? Also, what does it even mean? | California Dreamin\' is the title of a famous song by the Mamas and Papas.

2008 financial crisis and Wall Street | It was mainly precipitated by a housing bubble. There was a prevailing thought that housing prices could not fall. You could get a house without having to thoroughly prove you were able to pay for it. The thinking was that if you weren't able to pay for it your house would have gone up in value and cover the loss. Furt... |
Among animal species, why do humans have a need to be clothe, especially in public | I'm pretty sure it's just a societal thing. If you look at pictures of indigenous tribes in Africa or South America some of them don't dress for modesty at all but for tradition and whatnot. Basically, our society and culture has decided that the naked human body is something that should be covered up when in public so... |
What is the difference between having more or less blades on an airplane or helicopter propeller? | There are a lot of factors at play but I'll try to summarize. Firstly is efficiency. The more number of blades means that the system is less efficient. This is because the blade operates in the wake of the blade in front of it. The blade moves air out of the way and therefore the following blade cannot lift as well sin... |
What prevents the US from declaring peace with N0rth K0rea? | The US doesn't like to deal with totalitarian governments.

Why can't we make a glass bottom plane? | A lot of the time, the answers to "why can't we make " are just because it's not economical. Yes, we could make a glass bottomed aircraft. It would involve extra engineering costs and manufacturing costs. And it turns out that people don't want to pay a lot of money for things like this. So the answer is not that it's ... |
How do T-rex sleep with the big legs and small arms | This might be better directed at /r/askscience They have nerds there who will tell you all the current theoriesProbably similar to birds, seeing as they are the evolutionary descendant of dinosaurs. I think the ostrich is the most related to the t-rex, I could be 100% wrong on thatThey would squat down and place their ... |
How do our bodies get "use to" cold water? | Temperature sensing nerves work by temperature difference . So when you first jump into a cold pool, your nerves will react strongly to the cold water. Then, as time goes on, the temperature of your skin drops, so the nerves don't react as much.Same reason your house doesn’t have a “smell”, and why you can tone out a n... |
Is there a historical reason why the majority of Americans don't care about soccer even though it's wildly popular in the rest of the world? When and why did that divide happen? | A couple of reasons for this: - Firstly, soccer had bad timing. Soccer was becoming popular in Europe as baseball was becoming popular in the US. There was initially only room for one new major sport every now and then. Imagine, there's this new sport that everyone is talking about that is made in America called baseba... |
How do audio cassettes work? | Audio cassettes have a spool of magnetic tape, divided in to microscopic little sections. The information is stored depending on the polarity of each segment. When the tape passes through the machine, it 'reads' the sequence of norths and souths. It then transcribes them into electrical signals, which are sent to the s... |
How can the universe be both deterministic and non-deterministic at the same time? | The quantum world is inherently non-deterministic , but on a large scale it doesn't matter. Let's say there's a small chance that an electron in your body can quantumly tunnel somewhere it shouldn't be and interacts with another electron. So what? That will have zero effect for you. . The probability of non-determinist... |
How do phone calls work? How does entering a specific string of 9 digits put me in touch with that specific number? | Think of it like a mailing address. The phone company receives your call with the requested destination and then routes it first to the correct country , then to the correct area and then finally to the local telecom, who looks up the rest of the phone number and delivers the call to the correct person. Bonus: this is ... |
How are we able to know exactly when astronomical events will occur with a such a seemingly small margin of error? | Newton. Objects in motion stay in motion unless acted on by an outside force. We know where things are and where they're going. We might not know how gravity works, but we know the effects of it. Unless something comes and changes stuff around, we can easily calculate where things will be in the future. |
How exactly do the different settings on dryers (i.e. "Permanent Press") affect clothes? | According to [Sears]: > A washer on permanent press will wash clothes in warm water and rinse them in cool water, maintaining a mild agitation and spin.

Why is Sunday considered to be a weekEND even though in some countries it is the first day of the week? | The beginning of the week is also one end; Sunday is at the front end and Saturday is at the back end. Imagine the week as a ruler, with Sunday at one end of the ruler and Saturday at the other end. See how they're both on the end of the ruler? I had thought that in most English-speaking countries, the week was structu... |
How a happy person can still be depressed | There are 2 types of depression. Endogenous and exogenous. Endogenous depression is the type that is caused by chemical imbalances in the brain. For this reason it often responds well to antidepressants because they fix the brain chemistry. Exogenous depression is the type that is a human reaction to certain life event... |
Why does heated metal make clicking sounds as it cools? | Materials expand as they're heated and contract as they cool. What you're hearing is metal rubbing on metal where different parts contact each other as they expand and contract. |
When microwaving bowls of food, why does the bowl get hotter with certain items of food in it, when they time in the microwave is the same? | Microwaves work by agitating the water molecules in your food. If the food doesn't contain very much water, then the interaction is weaker and the food is heated less. |
what commonalities are there when large cultures abandon widely practised religions for another, such as the Greeks, Romans, Egyptians, etc.? | Well, the one commonality is their civilisation/empire collapses and breaks off into smaller bits.

Why aren't the Great Lakes considered seas? | Generally speaking, seas are bodies of salt water, which the great lakes are not. Seas are also generally considered to be bodies of water that are larger than lakes, but this distinction can be fuzzy, since there's no 'standardization' where a salt water lake becomes a salt water sea. Similar to the lack of a sharp di... |
Why dont we have hovercars and other hoverthings :D | > 1) Why cant we just use magnets on a car and use a magnet field on a road. Im not really an expert in this kind of stuff. And other things, a car is just the first thing that came to my mind. Mag-Lev, in its current form, must follow a rail. If we were to retrofit existing roads and cars with Mag-Lev technology we wo... |
What about a material (on the molecular or atomic level) causes it to be sticky? | What you call stickiness is known to scientists as [adhesion] . There are several different mechanisms of action - some things are sticky because they form chemical bonds to the material, some things are sticky because they infiltrate microscopic ~~pours~~ pores on the surface, etc. The Wikipedia article has a very goo... |
Cell phone flashlights shine a very bright white light. When you cover it up, your finger glows a very deep orange/red. Why is this? | It’s reflecting the light through your skin. Your skin is an orange/red color so it’s shining through that. |
Why do some words feel wrong after reading them a number of times? | I personally am a fan of this one. It's called semantic satiation, or sometimes verbal satiation. Basically, what it comes down to is, when people lose interest in something, they stop paying close attention to it. When you're exposed to the same word over and over again, it begins to feel like it's losing its meaning,... |
What exactly is soap and why does it do a better job cleaning than straight water? | Soap contains stuff that helps make grease and oil "stick" to the water, so that when you rinse, the water rinses it away. Water alone will take some of the grime away, but the soap enables it to get most, if not all of the grime. Often, the foam and suds that you see when you use soap actually isn't even necessary, bu... |
Why does ISIS in this video seem to be using equipment marked "US"? | They got it when ISIS overran Mosul.

Why is Direct Democracy not a viable system as opposed to what we have? Would it result in massive indecisiveness, if implemented? | Two main problems with direct democracy I can think of off the top of my head: - stability: the will of the masses tends to change quickly. News report on minor being raped and killed? Let's introduce death penalty. Mass shooting? Let's forbid guns. Note I'm not taking a stand towards either death penalty nor gun contr... |
how come certain animals don't need to lay down to rest? | cows lay down to sleep. some animals never fully lose conciousness while sleeping. usually they're prey animals that at any time need to run from a predator. if u were an antelope and you just passed out in the middle of the field, you'd wake up to a lion chewing your flesh.Some mammals are able to even continue swimmi... |
Why is orange juice from a bottle different from literal orange juice that's squeezed directly from an orange? | Supermarket OJ needs to be available year round to meet demand. Oranges are not in season all year. Orange juice is stored in vats and bottled with flavor packs to replace lost flavor. |
how do organ transplants work, specifically a kidney | > the doctors said it started producing urine immediately after being translated Producing urine on the operating table just means you've successfully hooked all the tubes up.

Now imagine the molecules of a bouncy thing a... |
if we drop a nuclear bomb on the Sahara desert, would it turn to glass from all the sand? | Yep. The first nuclear explosion, known as the Trinity test, is actually famous for being in the desert and producing [very impure and rough green glass shards]. This specific type of glass is known as [trinitite].If you're asking whether the *entire* desert would turn to glass, then no, not unless you drop a *lot* of ... |
Why does prolonged hyperglycemia cause nerve damage? | Hyperglycaemia tends to cause nerve damage, termed *neuropathy*, by damaging the microscopic blood vessels that feed nerves.

Training you on how to put a parachute rig on while we're crashing at 600mph isn't going to go well.To all the parachuter commenters. Doesnt matter. The doors wont open. Lets say you bail at 10000 ft. The diff pressure would... |
Would someone who enjoys performing anilingus have a more diverse, and thus potentially healthier, microbiome? NSFW | That's unlikely. But they probably would have a good shot at e.coli, c. difficile and maybe even toxic shock syndrome. |
What happens moments before someone plunges to their death. Shock? If so, what does that mean? | I once jumped off a 40' cliff into the water. There was fear, exhilaration, disorientation, but mostly, it happen too fast to experience much of anything. Even a 100' fall would take only around 3s. |
Why does soap work? The two major components (I learned this from Fight Club) Fat and Lye seem like they'd just make you feel dirty. | Soap is made from fat and lye, but saponification creates a new substance out of those two things that we call soap. Here's how soap works: First, remember that oil and water don't mix. So when you have grease and oils on your skin or your clothes, it is difficult to wash them off with just water. You could wash them o... |
Does 'BIDMAS' apply to strung together simple equations or only in complicated equations? | Neither, it equals 0. You always perform multiplication before addition/subtraction. When there are operations with the same precedence, you perform them from left to right. So 2-2x2+2 = 2-4+2 = -2+2 = 0. The order of operations always applies. Edit: oops, typoNot at all sure what that I is supposed to stand for, the a... |
Why are power companies allowed to hold entire cities/states in its monopoly? | They are regulated monopolies. There is no practical way to have multiple sets of power poles carrying electricity so you can have a choice. Electricity is a fungible commodity. It must be delivered to us at a standard voltage and frequency. So states and the Federal Government allow them to operate as monopolies while... |
What makes mould on food appear in a specific place before it reaches the rest? | Mold is spread through the release of spores into the air. The colonization of food is entirely dependent on where these spores land because they grow outward from there. |
How do mountains (ex: Rocky Mountains) form with no plate boundary? | 1. Take a piece of cloth and lay it flat on a table or bed. 2. Put your hands a foot or two apart on the fabric. 3. Push your hands together. That raises mountains up, then erosion shapes them. ETA: there are always plate boundaries in play, but the mountains are not necessarily near the boundaries. Also, the type of r... |
Why do DVD covers always look different than the movie posters, and usually much less cool? | I imagine it's because movie posters are designed to convince people to go see the movie for the first time at release, trying to cater to an audience that of course hasn't seen the movie yet, so they have to make the poster, and by extension, the film, look more impressive. DVDs are marketed to people who've already s... |
What is it about potatoes that cause them to retain the heat of four suns as opposed to the other ingredients in the soup? | Potatoes are made of mainly water. Water has a very good ability to store heat. You may be thinking "but suop's water too".

As for the injured, it depends on the degree of the damage - from normally, to a catheter, to an [urostomy]A tube called a catheter can be inserted into the bladder in practically any situation. That simply drains into a bag. |
Why does Norway have some of the world's highest gas prices despite being the 15th largest oil producer (1.9M bbl/day) | It's mainly because they tax it ALOT. This is to make an negative incentive to drive as much because of the negative effects of traffic, the impact it has on local environment and the global environment. This is also a huge way for the government to earn a lot of taxes which go to building infrastructure or other goods... |
Why are indoor-only shopping malls dying in the USA? | Most indoor malls depend on the very large "anchor" stores to pull people in. These are your Macy's, Nordstrom, and other department stores, for the most part. These stores aren't doing nearly as well with the advent of online shopping, so the foot traffic to the other stores suffer. With less foot traffic, the smaller... |
Why do paper cuts hurt so much for such tiny injuries? | As has been posted, they're still a cut and all wounds would hurt but it's speculated that a paper cuts sting so much more to a person because the cuts are so much more perfect they cut through more tissue exposing more to the air.It's not like a wider cut would "hurt less" paper cuts hurt because they're a cut just li... |
How is the movie "Airplane" only rated PG? | Mostly because PG-13 didn't exist until 1984, and Airplane came out in 1980. But also because people were less sensitive and lazy.Oh man, the 1970s were *awesome*. You should have been there.Because there wasn't enough objectionable content to raise it to an R rating, and at the time the movie was made, there was no PG... |
If we stopped moving through space, would we stop moving through time (i.e. stop aging or growing)? | As far as you're concerned, you already aren't moving through space. Everything else is moving around you. Relativity means that movement only makes sense when compared to the movement of other things. If something else is completely still relative to you, then you experience time the same way. If something is moving r... |
Are there tiny planets in the universe? If so, would potential life on there be relative to size? | The smallest "planet" that we know of is [Ceres] which despite only having a diameter of 952km is spherical. It is not considered a true planet however as it has not cleared its orbit of other objects, instead being part of the asteroid belt.

What is "Thundersnow" and why would someone get so amped about it? | It's when thunder/lightning occurs during a snow storm. To create lightning you need some really strong upper-air dynamics in place. Normally this is created by rapidly rising warmer air - like in a thunderstorm. In the winter, there is no warm air in place to rise and destabilize the atmosphere up where the clouds are... |
When someone says they’re not going to laugh, they usually are more inclined to laugh or just burst out laughing. Why is this? | If someone feels the need to say "I'm not going to laugh" - They're not going to say that in a situation where they don't feel naturally compelled to laugh. I don't walk into the office in the morning and tell my coworkers randomly "I'm not going to laugh" - it's in situations where I WANT to laugh, but am trying to ho... |
Why (if they are) does Quebec seek Independence from Canada? | Much of eastern Canada was a part of a colony called New France, with the areas near Montreal and Quebec City being the most heavily settled. When the Seven Years War between Britain and France ended in 1762, France ceded these lands to Britain. Most of them were unpopulated, and eventually settled British colonists, b... |
Why are there so few aircraft remaining from World War II? Aircraft were built in quantities that are hard to comprehend, yet many models have vanished entirely. | WW2 ended in a period of hyper-rapid aircraft development. New high tech fighters and bombers were practically obsolete by the time they were deployed. A new front line fighter type could be expected to serve for only a few years before it was obsolete. Old planes were surplus, a drain on resources, and after a few yea... |
How does triangulating a call work and how are police able to determine the location of a caller? | Mobile phone base stations often have multiple sectors - each sector will have an antenna or antennas that cover a certain direction. It's common to cover a 120º arc with a sector, using a three-sectored site to cover a full circle. Because of this, you can then tell vaguely which direction someone's in when they made ... |
why do large indoor areas use one giant flat fan instead of a couple small fans? | The purpose of those big fans is not to "blow" air on the people in the area. They are instead for [destratification]. When you have a building with a high ceiling you end up with very different temperatures on the floor vs. up at the ceiling. This causes a couple of problems. If your area is something like a gymnasium... |

What exactly is my printer doing when it's performing maintenance on itself? | This largely depends on the kind of printer you have . Lots of cheaper/personal printers rely on ink instead of toner. Because of the mechanism involved in ink printers it can easily get clogged. In order to unclog these, the printer ramps up the amount of ink being output - essentially changing the dial from "sharp st... |
Why are guns called M#, but have different names like M16, M4A1, M9, and even AR-15 if they're all made by different manufacturers, and sometimes describe the same gun? | "M" is just the US military code for a small arms gun. Afterwards it is assigned a number, like "M-14". They don't care who makes it, it now is beholden to the military rules For example in other areas, "F" is fighter jets, as in F-16 and "AGM" is for air to ground missiles as in AGM-114 ', "> Also, how can an M1911 be... |
why do posts on here have to start with "ELI5"? | Because people who subscribe to ELI5 have the posts peppered into the rest of their front page and feed, so seeing "Why does a high gear produce less power than a low gear?" in your feed along with r/askreddit and r/askscience might cause someone to give a very advanced answer without realizing that the post is an ELI5... |
