Why did the US and Soviets continue to expand their stockpiles during the cold war, even after each side had the retaliatory power to obliterate the others' industrial centers many times over? | Most of those nukes were intended to be used to destroy the other's launch sites before they could launch. It's a critical part of nuclear strategy: why are all the silos clustered in a few places in the middle of North Dakota and Montana, for example? But why aren't the all in one big facility, just sort-of spread out... |
a company like apple reports profits in the BILLIONS. Where does that go and why are people disapointed? | Let's say you earned $100,000 last year, and you reported you were able to put just $500 of that into savings. $500 might be a lot to the guy pouring your coffee at Starbucks, but you kind of suck at saving money, and your SO who wants to save up for a house is probably going to be pissed at you. Apple did the same thi... |
Why is it that parents go to great lengths to see that their children receive the best education available, yet do not take the time and effort to educate them as well? | Depends on the parent. In my house it's the school's job to teach my kids specific information; it's my job to teach them how that relates to life. So when they learned about the Civil War, we went to Gettysburg. When they read *Hatchet* we went camping and built campfires with flint. When they learned about weather, w... |

Why is there a little symbol for a link to CandyBox 2 on the bottom left of /r/adviceanimals? | The short of it is because there is a line of HTML in the page source: < h5 > < a href="_URL_2_; The < h5 > tag is being formatted by the css file [muRL57ENy-52RGha.css]: position:fixed;bottom:20px;left:20px;z-index:1000;margin:0;padding:0;text-indent:-99999px;display:block;background:url;width:16px;height:16px which i... |
How does the Obama administration justify removing the tax credit from the college 529 savings plan? | > I realize many middle to low income families don't know about this and therefore don't take advantage of it That was pretty much the basis of the argument. 529's are overwhelmingly used by wealthy families, so they labeled it as a tax break for the rich. |
what stops people from "counterfeiting" digital currencies? | That is the genius of the invention of blockchain currencies. Satoshi Nakamoto developed a "mining"/"proof of work" system that solves the "double spending" problem.

How do machines that accept cash payment determine that a five dollar bill is a five dollar bill, etc? | Optical scanning. An optical scanner looks at the denomination Portrait, and other parts of the bill to reduce fraud.

Counter steering on a motorcycle | Here's how I think about it.. Because the bike is moving quickly and heavier than you, you can't exactly muscle the bike into a lean like a bicycle . so you initially kick the bottom out from under you in the opposite direction to generate the lean you need for the turn. after the lean is generated the bars revert to t... |
In ancient and medieval times, did people really just kill disabled people? | In some cultures, yes. The disabled can in some cases be an enormous drain on time and resources, to the point of making life much more difficult for others.

Why wouldn't gravity cancel entropy? | If u/taggedjc explained your question correctly, I firstly I want to clear up your misconception of entropy. Firstly, entropy does NOT mean "everything gets cold and freezes to a halt". The heat death of the universe is when the universe reaches thermodynamic equilibrium where no thermodynamic free energy exists and th... |
If electric fields produce magnetic fields, and our brain/nervous system operates electrically, how do we not have electromagnetic interference disrupting our entire body's operation? | 1. The brain/nervous system operates mostly *chemically,* with electricity being used as a bridge between chemical reaction sites. So it's much less susceptible to this interference than a purely electrical device.2. The amount of interference absorbed is low -- notice that your computer and phone, which *are* electric... |
How does sunlight fade colors? | Sunlight is a form of radiation. This radiation can excite atoms and break bonds in the molecules which cause colors, effectively fading colorsThe main thing in sunlight that fades things is the ultraviolet radiation. Most people have heard of this term before. Many things with color have something in it called a chrom... |
Why do people oppose the Trans-Pacific Partnership (TPP)? | > Now, I haven't read the actual agreement , and I assume most people haven't either. Nobody has.

How is the eye of someone who has 20/20 vision and someone who has, say, 20/15 vision different from one another? | Well 20/20 means that you see at 20 feet what a normal person sees at twenty feet. 20/15 means you see at 20 feet what a normal person can see at 15 feet, so you have better than average vision with 20/15. I don't exactly know why this is but just laying a base for understanding. |
Why do websites exist that take you from one sketchy set of links and data to another and another and another? Who is this benefitting? | Your attention has commercial value.

To increase... |
how does currency/money work? If we donate 100 million to a country, it's not like we send a crate of money over | Money is just a representation of value. Bartering, trading stuff directly is inconvenient. So we invented money as a "value holder", for example instead of trading my goat for your 100 apples. But I don't want 100 apples at once as they will spoil before I can eat them all. I instead get 100 apple tokens as a promise ... |
How do the different baseball pitches work? | Baseball pitch movement is often based on something called the "Magnus Effect." Essentially, when a ball is thrown with a certain spin, one side of the ball is spinning in the same direction as the ball's movement and the other side is moving in the opposite direction. As a result, opposite sides of the ball are affect... |
Why is French the preferred language for body care products. | I don't have anything to back this up but for the North American audience stuff in French sounds more sophisticated and refined as shown by the use of French to refer to more refined versions of stuff like eateries are called restaurants, underwear is called lingerie, perfume, cologne, rotisserie and so forth |
Why is it that double decker buses have only been used in North American for the past decade while they've been used in Europe for more than a century? | lots of low bridges and efficiency are the main reason. A bendy bus can load and unload at twice the speed. Also less handicap accessible. The ones being use in the US are in very few cities or just for fun. I know the one that started up in Las Vegas, is more for fun than anything elseBecause there was no need - indee... |

How come uninstalling is faster than installing softwares/video games? | The answer is pretty simple: When you install, you have to write all of the files in their entirety and decompress them from how they're stored in the installer, then make records of all the files and potentially entries in common places to tell the operating system how to reference specific files. When you uninstall, ... |
How do you develop the ability to perform a backflip? How do you practice? | Trial and error is the way, but they usually practice this with a 2nd person catching them if they go head-down to the ground or they give them an extra push to make the whole flip.

Why is gas so expensive? | The price is set largely by OPEC , they say how much they want to charge per barrel of oil and it becomes the price.

Neither Canada nor the USA are members of OPEC, but because th... |
What is exactly is a "gut feeling"? | It's pretty much intuition. Many people feel this in their gut. You aren't sure why, but you "feel" like you know the answer. I usually feel a tingle behind my right eye, but sometimes feel a sensation in my abdomen. I'm speculating that this feeling has to do with release of adrenaline into the blood system. Adrenalin... |
Why does most of the land mass lie north of the equator? | "Land mass" is a bit of a misleading concept when discussing planetary geology, and particularly in regards to the formation of a planet's surface, as what you are really referring to is merely the exposed planetary surface not submerged under water. It has a lot of significance for us, but in that realm of science is ... |
Why is the term "socialist" a dirty word in American politics? | In most Americans' eyes, socialism is irreversibly tied to communism, which is synonymous with the Soviet Union, the US' geopolitical rival for most of the latter half of the 20th century. The USSR was communist, and also socialist, so both have always had a bad connotation. Most people don't understand that you can be... |
why popular american fast food and snack brands are found nearly all over the world but we never see any popular foreign fast food and snack brands here? | You may not be aware that some snack brands are foreign because you grew up with them.

Probably the largest foreign fast food place in the U.S. is Tim Horton's which is a Canadian doughnut restaurant wit... |
how to game advertisements that use false gameplay mechanics (ex: mobiles games) in commercials get away with it | There will be a small disclaimer that says "not actual gameplay" or a simiiliar phrase .

But they'll put the disclaimer in anyways. |

How 5 hour energy actually makes you stay awake | Most notably caffeine. It's fine if you do it infrequently but if you make a habit out of it it'll no longer help wake you up, it'll just get you to normal.

If I eat a lot before going to sleep, why do I wake up hungry? | I am on board with you mate. I experience the same thing.

If it's foods high in ... |
How does a Tornado Intercept Vehicle avoid being sucked up into the air? | Some of them have pneumatically-operated spikes that they drive into the pavement when contact with a tornado is imminentOne major factor is avoiding getting any significant wind under them in the first place.

Why does an automobile depreciate in value the minute you drive off the lot? | Let's say a brand new Ford Focus costs $16,000. Would you be willing to pay $16,000 for a Focus that someone bought, drove around for a little bit, and then returned for some reason. The average consumer is always going to choose the new car over the slightly used car, so dealerships are going to have to offer the slig... |

Given the emphasis placed on the separation of the three pillars of the American government, how can the president grant pardons? Is this not the executive messing with the judiciary? | It's built on checks and balances, not separation. Each branch can limit the other branches so no one branch is all powerful. Congress passes laws. The President can veto but Congress can override. The Supreme Court can overturn laws passed by Congress. See how everyone can check the other branches? Pardons are one of ... |
How is it possible for a person who was born deaf to understand spoken language the moment their cochlear implants are turned on? | The video you linked is somewhat misleading. The woman is "deaf", not deaf. By which I mean that she was severely hearing impaired to the point that she is classified as deaf, but **could** hear with hearing aids. In other words, she was never completely unable to hear. Thus she could understand English because she had... |
What is happening when our nipples get hard? | Body parts which can be become erect - nipples, penis, etc can do so because they contain erectile tissue, which is like a sponge.

Where are we with gene replacement and what are the challenges that need to be overcome for it to work in humans? | I 'd say that 10 years is too soon, but I'm not going to speculate on whether it's 20 or 50. We have some techniques, like a relatively new one called CRISPR, which allow us to edit DNA more easily than before. In cases where we know that a single gene is the problem, we can use this technology to fix that gene, but ri... |
The grammar in "I am become death, the destroyer of worlds" | It's a valid, but archaic form of the [present perfect] tense, which is used to refer to a past event that has present consequences.

Why don't we use microwave waves for water heaters instead of natural gas? | The speed at which a microwave works depends on the mass of the materials. That's actually a FAQ here . I timed this and discovered for my own stove and microwave, the break even point is just about one cup. The microwave is faster for less than a cup, the stove top is faster for more than a cup. For the amount of wate... |
Why do birds not get electrocuted when resting on a power line? | Electricity will take the path of least resistance. The electricity could go through the wire, or from the wire to the bird and back to the wire. People get electrocuted because they are touching the ground.

Google Translate's forming its own language | An article about it from Google: _URL_0_Little bit about training neural networks: _URL_1_ An artificial neural network was trained for different language pairs.

Why does a wet trampoline feel like it makes you jump higher? Does it actually do that? | I recon it doesn't the only think I can think of is if it is cold water, the trampoline fabric/springs might get tighter as the materials contract.that sounds like a euphemism from a galaxy far awayI always thought that the water acted as a lubricant, enabling the fabric to move more freely. Therefore, letting you jump... |
Why don't Mac's get viruses? | They do, its just that there are a lot more Windows PCs out there.

There seems to be a ton of contradictory information on what causes diabetes... how much of a role does excess sugar consumption play in getting it? | I am not a doctor. Diabetes is caused mostly by the pancreas, which is the organ in your body that produces insulin, which is a hormone that helps regulate blood sugar levels. There are two types of diabetes.

Why does bending material such as metal, plastic, i.e. eventually wear it down so much that it snaps off? | Bending stuff actually breaks the inside of the material, but hopefully not enough to break the surface. Some materials like metal and plastic are secretly buzzing and jiggling around on the inside, and might even fix some of those breaks over time, when warm enough. Sadly materials like wood or bread don't jiggle enou... |
Why is it that almost all black guys I have met IRL and seen on TV always have their heads shaved? | Because it's not the 90's anymore. Also Black hair on men longer then a half inch looks "savage" to many potential employers and clients, so professionally we have to keep it short. I had a luscious footlong Afro until I was looking for an internship this summer and one of my interviewers, a Black dude, suggested that ... |
When checking out a library eBook via OverDrive, why is there a limit as to how many copies the library has when it's a digital format? | I work at a library and do AP for bills like overdrive & similar. Each time the ebook is "checked out" we get charged. What we do is prepay the account for the year for the fees accrued from what's borrowed and also prepay a contract for the content on over drive and another for the use of the database. Basically it's ... |
Why can't Greenland just play their home matches in another country, if the only thing stopping them from joining FIFA is lack of suitable playing surfaces. | Because then their own fans wouldn't easily be able to watch the games.

Why can't we process ocean water so it's drinkable, instead of relying on rivers/lakes for our drinking water? | We can. And in some areas we even do. It is incredibly expensive though. And seeing as that people like their water cheap, it is more advantageous to get it from lakes or underground sources than desalinate ocean water.We can, and we do. One reason we don't do this in California right now because of the drought, is bec... |
What happens to things that go in our eyes? Like where do all of the eyelashes go that we blink into oblivion? | They fall out.

How is North Korea so well hidden from our view when the US has such high tech satellite imaging? | A couple reasons: 1. You and I don't have access to military satellite images. 2.
