Why do people fidget or move a lot when they have to pee badly? | Wasn't there this mechanism that blocks your bladder when you are being sexually stimulated? Might tie into that. Moving legs a lot/walking around to create friction down there, causing a false "will bang" alarm, preventing the pee.Naturally, you're going to want to try to move from the discomfort. Wether or not you ph... |
How is the value of currency determined? | I actually just read an excellent explanation for this on The Balance and honestly I don't think I could word it better. > The value of money is determined by demand for it, just like the value of goods and services. There are three ways to measure the value of the dollar. The first is how much the dollar will buy in f... |
Why do most large pride animals like flee instead of fighting few amount of enemies? | In this case, walruses are much more agile in water than polar bears. Walruses also tend to be somewhat near water when on land. Over thousands of years, the species has "learned" that the odds of survival are much higher by running away than by trying to fight. Standing up to a predator like that would require a coord... |
If highly-skilled economists understand money so well, why aren't they all insanely wealthy? | Because knowing what will probably happen does not mean you know exactly what will happen, when it will happen or if it even will happen at all. If you're an economist and you think that there is an economic bubble somewhere that will burst, does not mean that you know when that will happen and which companies exactly ... |
What are the possible ways of reducing the pollution around the world, more specifically Asia? | ok first off I'm going to assume this isn't a troll post, but please understand this is akin to asking some to explain physics. start here for further reading _URL_3_ , _URL_4_, and _URL_1_ a couple big options exist: solar: _URL_2_ pro: "free" green energy, available almost every where con: expensive/high pollution to... |
What keeps the baby in the womb sterile? | [They are not sterile]. But they *are* kept more generally germ-free than the rest of the body.

How changing a trigonometric function affects the graph drawn? | This isn't just trig functions, it works for any function at all. Start with a function f, and say you can draw its graph. Then: * f is the same graph, squeezed to half size horizontally.* 2f is the same graph, stretched to double size vertically* f is the same graph, shifted one unit right.* f-1 is the same graph, shi... |
Why does it hurt like hell when we hit our elbows on something? | Weird, usually when I hit something with my elbows it is the wall that cries pain Joking aside, when I hit something with my elbows it tends to hurt less than with my fists. |
If humans, especially males, are covered in hair, why don't we shower with shampoo instead of soap? | If you're just talking about cleaning, then you don't even need shampoo. Soap will clean your hair just as well as shampoo will. Shampoo only exists because people care about the aesthetics of their hair or to treat a condition like dry scalp. If you cared as much about the shininess of your armpit hair or the softness... |
How did team sports become such a massive influence on the education system? Specifically colleges. | Money. Colleges & universities earn a lot of money from ticket sales, merchandise, and television/radio contracts.

Accordin... |
The newest change in Facebook privacy settings. Do they actually use my info/pictures/messages? Can they actually make my account public? | This might be what you're talking about, and may help you. I'm not sure without more detail though. _URL_0_", 'No those stupid posts about "facebook cannot use my information blah blah blah" do. not. work. They fail to realise that when they signed up they accepted the terms and conditions of the site, which also cover... |
If sites like megavideo can be shut down by FBI then why those websites won't move hosting outside US? | My huge question is on what legal grounds they were shut down? They're just like youtube, they comply with DMCA. What the hell is the difference that made them get shut down?", 'They almost certainly will, but if they pass SOPA/PIPA/whatever the awful child-protection one from next month is called, any US citizen who l... |
What's so bad about Qatar hosting the world cup. | Essentially, Qatar has no work force whatsoever, so they have to bring in workers from other countries to build the stadiums. The problem is, the workers they bring in are forced into work contracts they don't understand that literally keep them in Qatar forcibly. Workers live in terrible conditions and are not given p... |
Why is America so obsessed with the Middle East? | The US would prefer to ignore them like they do with other unstable places like most of Africa. However the Middle East is a vital part of the world's energy market, which for the sake of energy reliability for the US and the rest of the world requires some degree of attention. |
Why do certain toys and boardgames have an upper age limit, usually 99. | For games designed for very young children, the mechanics might not be engaging for those who are older. Candy Land is great for a 3-year-old to learn colors. Not so much fun for a 12-year-old. For those with a high limit such as 99, it's simply a lighthearted joke, as they usually say from 9 - 99. If 100-year-old gran... |
How do monkeys know to peel a banana before eating it? | Monkeys in the wild don't [generally] eat bananas. Captive monkeys will and it varies from species to species and from monkey to monkey.

Why are interest rates for bank-funded credit (personal loans, credit cards, etc.) much higher than government bonds? | You're comparing the cost of someone else lending you money with you lending someone else money. Naturally, the interest rate to borrow money is going to be higher than the interest rate you're going to get from privately lending someone else your money - everyone wants to make money. Also, government bonds are more or... |
Why are some babies born with a full head of hair and others born bald? | I don't believe anyone *really* knows. Some say it's genetics or maternal hormones. Also, the hair on a newborn will shed anyway within the first six months, due to the hormones the mother was providing dropping off . Infants then go through a [telogen] phase where there becomes an even more noticeable loss of hair. So... |
How is it some people can consume whatever they want and still be lean? | While there must be some natural variation in the degree to which people process and metabolise fat-- in fact, genetic markers for predisposition to weight retention have recently been identified-- it always comes down to the amount of calories ingested relative to the body's needs and ability to metabolise fats, carbo... |
How can baby animals start walking basically immediately after their birth, but humans can't? | Some species of animals are *precocial* which means they are relatively mature and mobile from the moment they are born Humans are *altricial* which means our young are born pretty much helpless. But we are far from the only altricial species! Rabbits are born blind and hairless, for instance, which is why rabbits give... |
What happens to political campaign contributions when the candidate loses the primary? Who gets that money? | States and local governments create their own rules. At the federal level the funds go to anything other than personal use Typically donated to another candidate, party or charity.They spend that campaign money campaigning Or at least, that's the theory. I wouldn't be surprised if someone just pockets it.Usually they g... |
- Is Capitalism synonymous with "Survival of the Fittest"? | Capitalism is, by its very definition, win-win. Survival of the fittest is a very poor analogy for capitalism. Nature is cruel. The wolf's success comes at the cost of the deer's life. Its neither good nor evil, it just is. But its win-lose. The wolf won, the deer lost. Capitalism does not work like that. If I have a d... |
why is it medically recommended that people try to reduce swelling if swelling is an important part of the healing process? | First off, swelling causes pain. Secondly, the stretching and pressure that swelling causes can do some other minor harm. And can obscure other signs of a problem. But mostly it's less that swelling is part of healing, it's that swelling is a sign that something is wrong, and reducing the swelling is a sign that they a... |
Why do American police sirens go woop while European sirens go dee doo dee doo? | Sirens aren't actually as effective as you might think. Some drivers don't hear them , some drivers can hear them but can't work out what direction they're coming from, and other drivers panic and either crash or get in the way doing silly manoeuvres.

Why are people scared by and fascinated with seemingly supernatural occurences? | Basically? Evolution. Back in the day our ancestors that heard noises in the dark and assumed the worst outlived the ones that just went back to bed. Long story short, we confuse correlation for causation, and draw connections where there are none.The evolutionary response by /u/thesnack is the most direct answer. But ... |
How come the bombing of Hiroshima was never classed as a war crime? | All parties in WWII engaged in extensive bombing of civilian infrastructure. In a war of that scale it's simply not feasible to try and pick out military targets embedded in cities and towns, it's faster and more effective to simply pummel a city into submission. |
how does an airline such as United go about recovering from losing half a days worth of flights? | Airlines use a variety of tools to recover from irregular operations. The science behind most of these is called operations research. Recovering the crew and aircraft schedules along with the passenger re-accommodations is some hairy math. It's only been feasible to create combined solutions of all three with software ... |
How exactly do "memory" materials such as thermoplastic revert to their original forms? | So a thermoplastic is a plastic that becomes moldable at a certain temperature, and when it cools, it holds that shape. For instance, a glue gun melts a plastic to a liquid, which becomes rigid again when cooled. Thermoplastic. Now imagine we have a thermoplastic that when it gets hot, it doesn't melt, but it gets flop... |

Why do we continually need to search for new porn to arouse us? What exactly is it that eventually drains all previous porn off its original arousability? | Much in the same way we don't watch the same exact TV show episode daily, why we don't wear the same exact outfit daily, don't listen to the same song over and over in perpetuity or eat the same meal over and over in general. Your mind does not derive any more stimulation due to over saturation. The mind generally crav... |
Do high price exotic "trophy hunts" actually aid in wildlife preservation? | In theory, the hunter pays a lot of money to the park. Park then allows him to hunt down older animal or animal that is a danger to people. Money is then used to run or improve the park. In reality there is risk for corruption of the park rangers . For example: Hunter wants a trophy so he doesn't want to hunt old or il... |
What is the impact of the radiation from Fukushima on North Americans living on the west coast? Are the foods we eating really poisoning us? | No. The levels of radiation that are affecting any foodstocks are tiny. You could get more radiation exposure by eating a banana. |
[LI5]: How does Hinduism work? No dumbed down Buddhist explanations plz. Those aren't the same. | Inside the body of every living is a **soul**. The **soul** is like the inside of your head, like when you read to yourself. Hindus believe that this **soul** never dies. It just picks a new **body** when your current body gets too old or you have an accident and pass away. And this new **body** can be any living thing... |
the definition of 'chemical'. | It really depends on the context. Give an example of what it's referring to, and it will be easier to post defining distinctions. |
Why do some programs "not respond" but look perfectly fine? | The window rendering on your monitor is only part of the program. If one of the background functions fails, like fetching the next song from a server, the program can hang up while it waits for the operation to complete.

"To be dating someone" | If they're not your boyfriend or girlfriend, and you go out with them, you "went on a date". When they are your boyfriend/girlfriend, you're dating.

Since Reddit is part of the "slow the internet" movement, why can I access the website and move to subreddits without any latency? | The slowdown was metaphorical. There's a blog post, and a couple little style tweaks/images changed on the top banner and the sidebar alluding to this 'slow down', but performance-wise, nothing has changed. |
How does Cinavia on the PS3 work? (For science) | Devices that are Cinavia compatible they listen to the soundtrack of the movie. Somewhere in the movie there is an inaudible "key" and if this key does not match the media being played, Cinavia will kill the movie. You may notice if your movie gets killed you can skip ahead of the scene where it died and the movie migh... |
Would it be possible for consumers to boycott Mylan and if so would it help or hurt them? | The problem with boycotting Mylan is the same reason that Mylan is charging so much--lack of competition. Let's say you need a crayon. You have to have this crayon in order to finish your drawing. Kyle has a crayon for you to use, but he wants you to pay $600 for it. Most of the time, somebody else is going to be selli... |
How does a hazmat suit and gas mask work? how do they filter the toxins out and how long do they last for? | Gas masks work by passing outside air over a series of filters before it is allowed to enter the mask. The simplest ones use particulate filters that prevent large particles floating in the air from getting through. There are also chemical filters that form chemical bonds with harmful compounds and trap them in the fil... |
Why do probiotics sometimes cause diarrhea, gas, or other symptoms of IBS? | Probiotics and antibiotics can both affect the amount of 'flora' that live naturally inside your gut. Part of what those bacteria do is help digest things and create important chemicals that the body uses. Bacteria can act almost act like an organ in our body. Cows, for example need gut bacteria to be able to eat grass... |
The Green (sometimes Blue) Eyed Prisoner (sometimes Islander)Problem | If there is only one blue eyed person, then they know there are no other blue eyed people. The visitor says there is one, and they know there is one, and that it must be them . If there are two blue eyed people, then they both know there is only one other blue eyed person. They know the visitor has told that person tha... |
Why do corn seeds pop when cooked, and do any other plant seeds do this? | As the Industrial Revolution taught us, steam is powerful stuff. Inside the thick hull of a popcorn kernel is a jumble of proteins and starches called the endosperm, which also contains water. As you heat the kernels, that moisture turns to steam and the starch begins to “melt” into a goopy liquid, says Wendy Boersema ... |
Is there any reason we can't make computer cases airproof and make a vacuum inside to act as a cooler? | If my understanding is accurate, vacuum would work as an isolator, not a medium to dissipate heat. It would make your CPU radiate heat, like stars do, but the temperature on the surface would have nowhere to go making your CPU fry right away.A vacuum inside would be very very bad! The components in your computer are ge... |
Why do countries need so many nukes, isn't ten enough? | For countries like Russia and America, who are operating under the MAD assumption, if the situation is bad enough to justify using a nuke, you don't want ten, you want enough to make sure that absolutely everyone in the other country is dead. And you want to be able to do it even after potentially suffering a crippling... |
How much electricty would you need to apply to the ocean to harm animals in a larger scale? | electrons in a conductor repel each other. Take a solid conducting piece of metal. Free electrons will push themselves apart and thus to the edge of the conductor, the middle will get 1 electron that doesn't move, the outside will have a higher density of free electrons. The current will follow in a similar manner such... |
In the past ten years it seems that people have become more negative and less community-friendly, especially between age 16-30. What causes these types of social trends? | "We are we are the angry apes, we don't like to look at no empty plates." When the economy is strong and things are going well, people tend to be more community oriented. There's a sense that there's enough to go around, and that even if others are making the wrong choices or exploring lifestyles that are very differen... |
What exactly is it that gives a car its 'new car smell and why is it that the smell disappears over time?' | It's the off-gassing of carpet, upholstery, vinyl, glues etc. Same as a house if you install new flooring and such. Once the VOC's dissipate, the smell goes too |
Why is that a browser needs 5-10 million lines of code? | A browser needs to understand, and interpret, the various commands and files that web servers send; web pages are instructions for your browser on how to put together the text, images, videos, and menus, for you to see and interact with. You can right-click or go through the menus and you'll see an option to "view sour... |
How is it that you become so fatigued during long car trips when all you are doing is sitting down? | Not a scientist, but I'd guess it has to do with a few things. First, when you sit still for long periods your muscles get stiff, and compounds such as lactic acid and others get trapped in your muscles, leaving them stiff and sore. I'd imagine that sitting still in one place for so long also triggers other hormones to... |
how were shadows burned into the walls in hiroshima? | The objects blocked the radiation from damaging the surface behind them, the area around the objects were unblocked and therefore damaged. The shadows weren't burned, everything else was.Radiant energy from the bomb would have heated exposed surfaces; since the flash was brief, heat would not conduct significantly in t... |
If scratching rashes makes them worse, Why do we have a natural urge to scratch? | A good overall statement to make about mammalian biology is that not all responses are good ones. Many times we have "maladaptive" responses that end up worsening the situation. Two examples I have are when inflammation spreads from just a local site to systemic circulation in your blood and all throughout your body. T... |
How does repression work and why does the repressed memory subconsciously bother people if the memory is technically gone? | You probably couldn't find it mentioned in /r/psychology because the concept of 'repressed memories\' has never been accepted by mainstream psychology. Researchers like Richard McNally have written a number of papers on it ) but the general conclusion is that what people think of as "repressed memories" are in fact jus... |
What is it that lets us be able to know if a voice comes from a black/white/asian person? | The differences you hear between speakers of difference races usually are related to speech and language patterns. For instance, many African Americans use an accepted English dialect called African American Vernacular English. While many people would recognize this as an "accent" a dialect differs in that it encompass... |
Why isn't there a designated Sunday for Easter? Why does it change up every year? | The date of Easter is the first Sunday after the first full moon of spring. This is because the date is based off the Hebrew Calendar, not Gregorian calendarBecause the date of Easter is calculated relative to the date of the first full moon after the start of Spring, which changes every year. Why is it based on the fu... |
What is the Atwood machine good for? | When students are learning physics, they tend to use simplifications such as frictionless machines. That makes experiments difficult, as we don't have frictionless machines. The goal of experiments is to give students something real-world to work with, to increase engagement. Atwood's machine can be made relatively fri... |
What are Lagrange points and how do they work? | It's 1am here so this might be a little oversimplified and weird; lagrange points are points in space where gravity of different celestial objects cancel out. You might know that larger masses cause a larger gravitational pull. Also, gravitational pull is quadratically inverse to distance, meaning the further away you ... |
How does Avast isolate viruses in its virus chest and prevent them from spreading? | Because it doesn't store the entire virus, it simply stores a signature of the virus. Think of it like a wanted poster. The program knows what it's looking for even without needing to have the full virus in its database. EDIT: I just realized that you might be referring to quarantine and not the virus signature databas... |
How can South Park depict Richard Dawkins having sex with a transexual or Kenny crawling through Paris Hiltons gaping vagina without being sued? | They do get sued on occasion, from what I understand. The Church of Scientology has sued them several times.They claim it's satire, and have been taken to court and won enough that any cries about it harming their character is countered with the fact that everything on the show is silly and not to be taken as the news!... |
What do we use Quantum Mechanics for? | The most important technology we use that relies on quantum mechanics is semiconductors. Semiconductors are materials that are between an insulator and conductor in terms of how they conduct electricity. Rather than list all the uses for semiconductors, I'm just going to tell you that if you name a random electronic de... |
I kissed a girl and my eyes sting. | Assuming it is indeed the kissing that's leading to this, I'd agree that her makeup is the most likely culprit. Lots of people have allergies to certain makeup ingredients. If it's not too awkward, find out what type of makeup she wears and do a little research . |
Why do women (and people in general) have 2 breasts instead of 1? | Someone once told me that each species of mammal has a number nipples to accommodate the highest number of offspring the female can safely carry to term without medical intervention. Sorry, big words:Human women have two breasts because: TwinsSymmetry. Imagine how unhappy the guys over at /r/mildlyinfuriating would be ... |
Why are children kept in the dark about sex and sex related things until a much later age? | You are most likely from the US or maybe Canada. In many countries it is treated as natural and like a bodily function.The US was founded by very religious who shunned sex and all things related. Canada follows a little bit but usually this is due to our Southern neighbor. Quebec for instance has a much more lax view o... |
Does a reduction in the amount of protein taken in lead to reduction in muscle mass? | Yes. All your muscles need protein to maintain, due to tiny tears that occur in day to day life. Also, your body will force itself to lose muscle mass if you are in a calorie deficit, as they use so much protein just to exist.Calories In / Calories Out is actually a usually accurate approximation of the 3 macronutrient... |
Why do things smell different when wet? | The moisture level in the air has an impact on your ability to smell. For the most part the more moisture in the air, the better you can smell things. Just after rain the moisture level is very high. This combined with the water carrying particles as it evaporates creates a more 'intense' smell. |
Why do some body parts ache when in the same position for so long, but not ache after sleep? | You move when you sleep. Also your body and muscles relax in a way that they don't when you're awake. |
Why do many employers run a credit check on potential employees? Why is this considered a valid element in evaluating an applicant's qualifications? | There's a point everyone is missing here. Credit agencies make money off selling people access to your report, so they figured out that they could advertise it as a way to help screen employees, because huge companies are always looking for quantifiable ways to determine if people are worth hiring . Instead of just sel... |
How metal detectors work. | They work by reading changes in a magnetic field. Even though Ferrites are the most magnetic, all metals will "warp" a magnetic field to some extent based on the type of material, the density, the volume , and how much of that material is within the field radius. A metal detector sets up an electromagnetic field of a k... |
How is someone who has lucrative stocks actually rich? Do you have to sell your stocks to realize any fiscal return? | Those people are potentially rich, not actually rich. Your are correct. The shares/stocks would have to be sold while still valuable in order for the owner to be actually rich. Think of it like a collector. Your antiques are potentially valuable if sold at the right time, but you don't get to spend money that you haven... |
Why did it take European leaders a year to finally confront Putin? | * First of all, economic sanctions **have** been instated.* Secondly, Europe with so many countries that have to agree faces a much greater challenge to all get in line on issues like these than Russia which just has Putin to decide everything, or even the US.* Thirdly, Europe is much closer to Russia and would be dire... |
How does the sun provide us with vitamin D? | It does not. You store a substance in your skin that changes into vitamin D when exposed to ultraviolet radiation, which the sun happens to provide. |
Why do I look so ugly when I take a picture of myself, but look good on the mirror? | [This gif will help.] Lighting. Lighting can change how a person looks. In normal day-to-day life, light sources, whether they be from the Sun or lightbulbs, are usually above you. When the light is here, the shadows appear in locations the brain is used to. Everything looks normal. But in a camera picture, the light i... |
Where does all the money go from hugely successful movies? | Most of it goes to the studios, who provide the money to produce the movie. The writers and actors usually get an agreed upon percentage of the gross revenue the studio receives from theaters and DVD sales. The studios keep the bulk of the profits because they paid to make the movie. Funding a movie is a very risky ven... |
If 'competitive' products are both owned by the same company, what's the point in competition? | They profit from both products. The consumer's just feel like they have a "choice" between two products.Often they target different demographics. Generally, you want to have a product for each demographic in the same line. Like Proctor and Gamble make both Secret deodorant and Old Spice Deodorant. Recently Old Spice ha... |
Regarding the OnePlus5, why does inverting the screen cause the "jelly" scroll effect? | It's *probably* a trick of the eye combined with a software behavior. Especially considering some users with phones not made by OnePlus can get the same effect by inverting their phone and scrolling. The screen isn't updating the picture all at once. It updates chunks. If you go frame by frame on that video you may not... |
Why are you supposed to always add acid to water and never water to acid? | Water can absorb a great deal of heat. Acid, not so much. So if you add acid to water, there's more water than acid. As the acid mixes into the water, it produces heat. There's plenty of water to absorb the heat. But if you add water to acid--initially, at least--there's more acid than water. It can't absorb the heat, ... |
How is it possible that animals can fit so much complexity into such tiny brains? | Because nature creates bajillions of them, each of them a little different from the other, and lets them run wild. The survivors get to breed. With our technology we don't tend to create bajillions of experiments running in parallel. |
How could IBM photograph atoms? | Electron Scanning Microscope perchance? Someone more educated will probably have to tell you for sure, but quite obviously electrons are smaller than atoms.They don't photograph them in any conventional sense. Rather, they use a device called a scanning tunneling microscope which moves a very sharp needle over a sample... |
Why is 'austerity' being used for governtment budgets when in most places the total budgets are not even going down? | Austerity can consist of holding budget growth below revenue growth, until the budget is balanced. This can be preferable to larger cuts, that can hurt economic growth and reduce revenue by a greater amount than the budget cuts.Politicians very often do not tell the truth. I'm not sure what more there is to say on the ... |
I've had a few, so I apologise if this is a stupid question, but why is your piss clear after drinking a bunch of beers if beer dehydrates you? | Put simply, it dehydrates you by causing you to piss all your water out.

All of these different... |
Why is it when you download something, it generally downloads at a constant rate, until 99% where it seems to stop and take a lot longer to reach 100%? | because the file is most likely downloaded to a temp directory then copied in its final destination when it's finished. the last 1% is longer because of the time it takes to write the file on your disk. most likely, unless you use an SSD. |
How do speakers replicate so many different kinds of sounds? | Sounds are an air wave . Speakers reproduce this vibration so we can hear it. Of course they have limitation but the are made so common sounds that we can hear are reproducible. It will not create exactly the same sound as the original event but it will be close enough for most of usThink about how the ear works. There... |

Where does lost money from the stock market go? | It doesn't "go" anywhere because it isn't "lost" in the conventional sense. Let's say that you buy a Charizard card off of me for $100.

How do adhesive factories (super glue, caulking, etc...) prevent their machines from seizing up with dried glue during production? | When the glue is running in the pipes it's usually not exposed to air and it spends very little time in the tube so it can't clog up. These factories might be running the filling machines 24/7 or when the machine is turned off, they run a solvent through the pipes to clean the left-over glue. |

What would happen if Russian and American soldiers end up killing eachother in Syria? | Russian soldiers are not in Syria, and will not enter Syria. US soldiers are not in Syria, and currently have no plans to enter Syria. So I don't think your question is really answerable; there are a ton of things that would have to change before it could happen. |
What would happen if a person tried to live in Pripyat or any irradiated area ? | Radiation causes DNA to mutate. If DNA mutates in certain ways, this can develop into cancers. Living in these areas increases likelihood of developing cancer. EDIT: this is assuming there's only minor radiation in the area. With high levels of radiation, cells begin to die, leading to organ failure. |
