Will two people searching for each other in a crowd reunite faster than one person searching and the other standing still? | I don't think the question is valid unless you know the behavior and layout of the crowd. * If the crowd is in a line , and the line is thin enough to where you could see each other on if one person was on one side of the street and one on the other, you could then solve it in one dimension. * If the crowd is in a squa... |
Why are so many NFL players supporting Richie Incognito? | Many players are defending the status quo / culture of the NFL more than they are defending Incognito.

The kid gets upset and quits the... |

Why do some people hate having fluoride in things we consume. | This usually turns into a debate on whether fluoride actually prevents cavities or is a rip on conspiracies of poisoning the people. If people want fluoride to prevent cavities, why can't they just go and buy it or get a cleaning from the dentist? Why must it be put into the water supply? Regardless of any debatable ef... |
How does stopping the affordable care act /Obamacare advance the Tea Party Agenda? | Because your post isn't asking a simplified conceptual explanation, but rather for an answer, its been removed. You should try /r/answers, /r/askreddit or even one of the more specialized answers subreddits like /r/askhistorians, /r/askscience or others too numerous and varied to mention. Rest assured this doesn't make... |
Why are time zones still a thing? | It would actually make travelling a lot more difficult.

How is it that your chances of winning the lottery are about the same as getting hit by lightning, yet when someone hits a big jackpot there are multiple winners? | There aren't *always* multiple winners. But when the jackpot size gets really large, a *lot* of people start playing; people who normally do not play the lottery at all. To use the lightning analogy, it's as if a hundred million people suddenly decided to go stand outside during a storm. It wouldn't be all that surpris... |
How Pirate Bay can still keep their website live and not get taken down for illegal file sharing. | And I'm pretty sure its run by the swedes who have little to no fucks to give about piracy.For the same reasons Google can keep their website live despite all the illegal things that are linked in the search results.

How come sharks have survived from the time of dinosaurs, but other large sea creatures such as Mosasaurs and Plesiosaurs did not? | The same reason that megalodon isn't around: environmental changes made those large creatures unable to live.

Can someone PLEASE explain the traditional garb thing? Why is everyone so aggravated with it? | Somebody posted a picture: [Transylvanian Women in Traditional Garb]. It wasn't that interesting to begin with, because the take-home message was Check Out These Hotties In Vaguely Ethnic Attire. Since then, every Redditor thinks they've got [just the funniest follow-up.] A few are amusing, but most are either racist o... |
Why are fatally ill patients generally not allowed to try experimental/non-approved drugs that may save their lives? | Because those stats get recorded for the drug anyway. So this guy is pretty much gonna die no matter what, and this drug that might or might not help is going through trials. Say, 100 test subjects. We could put this guy in and make it 101 test subjects, but since he's gonna die anyway Basically 100 test subjects 2 die... |

Processes and Threads in computing. What exactly they do and so on. | Or the more ELI5 version: Imagine working at a restaurant and someone orders a hamburger. You need to find out what they want to eat, prepare the ingredients, cook the hamburger patty, make the sandwich and then give it to them. There are somethings you have to do in order and others you don't . Processes and threads a... |
If testicles are so crucial for procreation, why are they so vulnerable and not inside the male abdomen like ovaries? | The maintenance of semen and sperm in humans requires a temperature that is significantly lower than the normal human body temperature. That requires the testicles to be outside of the main structure of the human body. Since one male can impregnate thousands of females, it is not very important for a human male's repro... |

How did New Horizonz technically photograph Pluto? | The human eye sees light in the visible spectrum of the [electromagnetic spectrum], but what we can see makes up a tiny fraction of the whole spectrum.

Why is it that some vegans don't consume/use products made from animals but don't consider fuel/oils an animal product? | Why would you consider fuel and oil an animal product?

If I am listening to two audio streams, what is happening when our brain switches from focusing on on stream to another | I'm not hugely knowledgeable in this field, but there's a part of the brain specifically devoted to focusing on different audio.\r\rThere's a condition / disorder where people are unable to concentrate on a single audio source, and makes being in a crowded place a very difficult experience. The name escapes me though, ... |
Why does my iPhone jump from 15% to close to 40% almost immediately upon plugging it in to charge? | Fast charge - think of it like colouring in a large shape. It's pretty easy and quick to shade in the empty space in the middle, but you need to slow down and be more careful once you get to the edges so that you don't go outside the lines. When you plug the charger in, it quickly shades in the middle area before slowi... |
Won't the Oculus Rift and other VR systems effectively half the graphics processing speed since it needs to render two images from distinct angles? | It does take a lot more horsepower. However, it doesn't take twice as much, because a) each image is only half the size, and b) not all of the work need be completely redone for each eye. I would be interested to know exactly what the tradeoff is. I imagine that a game designed specifically for binocular 3D would fare ... |
How is it that oxygen exists only on Earth but not in space? | It does. For example Saturn's rings made of water which is molecule of hydrogen and oxygen. Molecular oxygene is not so widespread, but you should understand that space is not very dense and 98% of the unverese is Hydrogen and Helium. If fact, Oxygen is 3rd most spread element in space.There is a lot of oxygen, for exa... |
How or why did our bodies evolve to have a normal temperature of 97.8-98.2 degrees and not something higher or lower? | You're kind of thinking of this backwards. Body temperature is the *equilibrium temperature* of our body. See, your body is constantly making heat. That heat is escaping into the environment. The rate at which heat is produced in the body, and the temperature difference between the body and the environment, determines ... |
How do we know the documents being released by Snowden are true or haven't been edited by a foreign power? | Remember that even though there are not a lot of people ALLOWED to comment on the material, there are a lot of people who actually do have access to it .

Actual question from my 5 yr old: Our cat sleeps most of the time and he grows up. Stray cats in our neighborhood are always alert. How do they grow up? | Sleeping is not actually related to growth, as far as I know, at least not significantly. Sleeping is more for letting your brain organize itself, and physically resting allows the muscles/tendons/etc to recover from the day's labors, but the amount of energy saved by not moving for hours a day is not nearly enough to ... |
why are food allergies like peanuts/dairy/eggs so common and potentially deadly? | Having any kind of food available anywhere in the world is a relatively recent phenomenon. For most of history certain foods were localized in certain areas, so people whose ancestors ate those foods regularly for generations process them differently than people whose ancestors never touched it. Take dairy, for example... |
What physical changes occur in a hard drive or USB stick to store information? | On hard drives it's the polarity of the magnetic material that coats the platters that stores the binary information", 'So how do HDDs generally compare to SSDs in terms of longevity?Basically millions of switches that are either on or off. They are ordered in certain ways to format whatever it is storingFlash sotage m... |
Why does everyone hate the Patriots so much? | I'd also like add that the AFC east has been a joke for almost 2 decades which virtually guarantees the Patriots get not only 6 easy W's but then they have automatic an playoff appearance. Plus the 6 easy W's help them get home field advantage in the playoffs during the coldest times of the year in an outdoor stadium. ... |
How is stomach acid formed inside the human body? | Two separate, mostly harmless chemicals are made in your stomach's walls. Then they throw them into the stomach where they mix and make acidon the other side of the snot lining inside your stomach.cells in the stomach produce chlorine Other processes in the body produce Positively charged Hydrogen Ions as a waste produ... |
If holding elections entirely online would be less costly, more eco-friendly, more accurate, and yield a higher number of voters, why doesn't the US government do it that way? | Many of the points you presume in your question are controversial, but folks have already started to jump on them, so let's try letting them slide. An important aspect of elections is trust. People have to trust that the system is legitimate in order to not object to the legitimacy of the result. Paper ballots make sen... |
How did every ancient civilization develop gods or religion separate from each other? Like why did they all just decide that there must be gods? | I remember hearing a discussion point from either Hitchens or Dawkins which went something like this : Our propensity for wanting to believe in the super-natural may have a lot to do with our evolution as a prey species. After coming down from the trees to forage for food and hearing a rustle in the bushes, 90% of the ... |
When you are stretching really intensely, like when you wake up, why does your ability to hear diminish greatly? | I realized that I could voluntarily do this as a young kid by yawning. I would yawn and feel it in my ears and just taught me self I could do it anytime. I would do it if I didn't want to hear something and it wasn't polite to cover my ears and I'm mind blown that it's actually a thing other people can do", 'Also, an i... |
Why do people think the moon landing was faked? | The ELI5 answer is very simple: A relatively large percentage of our population is stupid.

Stupidity is the inability to apply reason, especially to ones own opinions or preconceptions, and a significant portion of the population is afflicte... |
How many sentences can we form in the English language? | My favorite number is two", etc. There's an infinite amount of numbers, so you can build an infinite number of sentences by following that format.No. There is no strict limit to how long a sentence can be. As such there are an infinite number of possible sentences, and we obviously can't use that many. Note that most o... |
Why do Americans treat people in the Military with high regard but don't give the same respect to police officers? | Because they're two different things. The perception is that soldiers are defending us, and police officers are detaining us.For the most part, we do. The problem is that individual officers keep breaking the trust and behaving corruptlyThe vast majority of americans do respect police and hold them in high regard. This... |
Why is 350 degrees farenheit the optimal baking temperature for pretty much everything? | In the end pretty much everything is made up out of the same basic ingredients, in very slightly varying proportions. I used to work in a traditional bakery. The vast majority of things are made using the same liquid to dry material ratios. The doughs and pastries have very little individual variety to them. So then it... |
How much money do I need to start investing in the stock market? | You don't need any money. Just use something like Yahoo Finance to paper trade. TD Ameritrade if I recall has no minimum. Though for practical purposes maybe 1k. Really the most important part of this, is getting started. |
Why are over easy eggs safe to eat if the yolk is still uncooked? Wouldn't bacteria still live in it? | The main risk is salmonella, which can get into the egg through the hen's intestinal tract, ovaries, etc. Most eggs, however, are sterilized before shipping. If they aren't they are labeled as so, but even eggs that haven't been sterilized are pretty rarely contaminated. For instance, you're more likely to get sick fro... |
Before i go to bed i will weigh myself and again straight after i wake up and i'v lost 1-2kgs. Where did that 1-2kgs go? | First, you probably do sweat while you're sleeping, even if you don't wake up sweaty. You also lose water through your breath. Water loss makes up the bulk of daily fluctuations in your weight. Second, you're constantly breathing out the products of metabolism, especially CO2. That carbon is, pretty quickly, actually, ... |
How does AI ever lose at chess? | It would be possible if a computer wasn't bound by memory constraints. There is something called a [Game Tree] which essentially shows every combination of possible states that a game board can be in, and the transition from one state to the next by making a move. For a game like Tic-Tac-Toe, which only has nine square... |
What exactly is catnip and why does it do what it does? | There is a chemical released from the plant leaves that 'mimics' a pheromone that would normally come from other cats. The catnip itself has no pharmacological action. Meaning that chemically, it does not do any thing. When the cats breath it in, it attaches to receptors in their nose/sinuses and induces the release of... |
Woman gives birth and says she didn't know she was pregnant. Is this possible? | I knew a girl. She was hot. She quit going to dancing class and started to gain a little weight.

A few months earlier she had to t... |
Given a constant stream of oxygenated blood, can a brain think by itself (with no body attached)? | In all likelihood yes, assuming that waste was disposed as well as blood and nutrients were able to get in. Everything the brain needs, oxygen, nutrients, waste disposal, a system of moving all this junk around, is presumably taken care of so there's no reason to assume that the brain wouldn't function as normal.This c... |
How do the wings of a plane produce lift? | Lift **can** bee properly describe by Bernoulli's Principle [when it's applied correctly.] However, most people don't apply it correctly and imo it's more confusing than the alternative: Newton's Laws. According to Newton's Laws, the plane generates lift because it's [angle of attack]. When air hits the wing, it's dive... |
Why don't people who pay fines for crimes like speeding pay an amount based on their income, the same way it is done in taxes? | Bottom line, it comes down to people's ideas of fairness. Scandinavian countries believe that the rich and the poor should feel equal amounts of pain from a fine. Americans believe that both having to pay the same actual dollar amount is more fair, and paying a percentage of one's earnings is to punish someone for bein... |

The delta-epsilon definition of a limit | Think of it as a game. I get to pick a number and you have to find a number such that if x is within delta of x0 then f is within epsilon of a . If you can find a delta for every epsilon I give you, then we say the limit of f as x goes to x0 is equal to a. If not, then it isn't. |
What is the real world significance/ benefit of calculus? | Finding the volume of solids with sides that can be represented by an equation, like if you have a lathe that can move its cutting bit in and out based on an equation like y=x^2 , you can use calculus to find the volume of the piece of metal you machined with the lathe. You can also find the rate at which a container w... |
Cold beverage + cup = wetness outside of the cup. Why? | *Liquid* and *solid* are what we call *phases* of matter. There's another common one: *gas*. Liquid water is what we usually call water. Solid water is what we usually call ice. Gas water is called water vapor. And the air around us is actually full of water vapor! It's all over the place. In fact, if there isn't enoug... |
Why is Graphene not used to solve / better practically applicable aspects of life ? | It's expensive to produce in the quality that would make it useful, which makes it too expensive to use in Mass market consumer products. Right now the process involves a lot of time and human hand, so it is costly.Because all of those things don't exist inside a laboratory. Which Graphene, like any "20 years from now ... |

Refusal to Cooperate with Police? | I was prepared to just say it was Americans being stupid, but after watching that..I think in this case it's perfectly valid. They're randomly stopping people at checkpoints that are acting as a border crossing, but they aren't borders .it's just checkpoints they have put up in locations. They also aren't just asking s... |
During sunset, the sky acts like a prism, changing color from blue to red before going dark. But it skips one color of the spectrum -- green -- why? | The color change of the sky isn't due to the separation of the spectrum of light as in a prism, but rather due to scattering and the gradual increase in the amount of atmosphere the light needs to travel through as the angle increases. The orange and red light penetrate progressively farther so the total lighting is sl... |
Why does deep breathing help prevent pneumonia? | Med student here. This sounds like bullshit. I'm going to need a source for this. Life Pro Tip: if you're researching something scientific and the source doesn't contain .gov, or .edu, or .org, or CDC, or NIH in the link, it's not legit. |
Why is the discredited Laffer curve still so prevalent in conservative economics? | One simple reason that US Conservatives prefer the Laffer curve is simple: in general, US Conservatives are against taxation. The concept gives conservatives a simple and intuitively obvious way of justifying a tax cut. As McK pointed out, the problem isn't that the Laffer curve is wrong, the problem is that it's impos... |
When water boils, how does the air that bubbles up get to the bottom of the container? | Those air bubbles they are made out of water! Trouble is, too many books teach us that steam is a white cloud. No, steam is a transparent gas, same as air. If it's white, then it's not steam, it's fog, it's made of liquid droplets of water. If you have a whistling teapot on a stove, look at the little hole. The clear s... |
What is hunger a signal of? The need of nutrients or energy? (and some follow up questions) | Here's my jab at a 5 year old explanation for this question. Basically, when you get hungry, you're body can be telling you a lot of different things. Among those, its that your body needs some sustenance for energy and keeping your body working. Getting hungry can also be very psychological . When people are bored, so... |
Why doesn't the American government prop up the oil companies currently struggling the way it did banks during the great recession? | Why should it? The banking system continued liquidity and operation was critical to the economy continuing to function in any way, and the banks risked complete bankruptcy without aid. The oil companies are still doing fine, just not raking in money hand over fist as they had been and their relative well being isn't mi... |
Why does breathing suddenly seem to become "voluntary" the moment we think about how involuntary it is? | Your mind focuses on one thing at a time*. Breathing is something your body does by itself, without you having to think about it - like a heartbeat, or turning food you eat into something your body can use so you're not hungry any more. But unlike those things, when you think about breathing, you suddenly focus on that... |
How are protesters able to move through clouds of teargas with little to no visible effects? | I don't know that they do, but some people wear protection and some people, like me, just happen to be immune. |
Why are police lights sometimes only visible from behind the vehicle? | Cop here: Most control boxes have different settings. One of those settings is rear-only.

Why do some people constantly sway side to side when standing in one spot? | I don't know about everyone else, but once we had our first kid I found myself swaying back and forth when standing and talking while holding the baby. Pretty soon it became a habit I catch myself doing nearly anytime I am standing and talking. I laugh inside every time I catch myself rocking without a kid in my arms. |
Anxiety attacks , why do they happen only to certain people and how to cope with them or maybe eliminate them from your life based on expirience? | I would Like to know too.

So I Just go Home when he is there. Dont know what triggers it, maybe it's the unconscious hate aga... |
How Come Space Probes that travel to distant planets not collide with the smaller objects in space? | It is true that other people wrote - that it's not easy to hit something large because things are far apart in space. However, most probes and satellites are equipped with special multilayer honeycomb core protective shielding to give some protection from micro-meteoroids. Also probes are often rotating to use gyroscop... |
Why do people posting pictures of cars black out license plate numbers? If you've ever parked your car in public thousands of people have seen it | Your licence plate is registered to your home address so it can be extremely easy for someone to get a hold of your information and use it against you especially if you're famous. |
- How is it that Ticketmaster seems to have a total monopoly over all things tickets, or, why does it cost $18 to mail me tickets? | Performing arts has to get the majority of their funding from ticket sales. When the economy experiences inflation, and the government cuts grants and funding it costs more to produce a show and their receiving less money to do it with. That money has to come from somewhere.

Automakers are p... |
Network routing in particular OSPF | Easiest way to imagine it is to think of it sort of like Google Maps. Let's say you want to go from your house to the mall. You route the map and Google presents you with 3 different routes to take. Route 1 uses major streets and a highway and will get you there by driving 5.1 miles with only 2 stoplights. This route i... |
What was smoking tobacco like in the 1700-1800's before all the carcinogens were added, and was it as dangerous to your body as it is now? | Carcinogens weren't *added* to cigarettes. They're almost all a natural part of the tobacco or created in the burning process. It's not like every tobacco company on the planet has been conspiring to add carcinogens to their products for no reason and with no exception. Yes, smoking in the 1700s was as bad as it is now... |
What is really going on when you are in the hospital? | Mostly, he'll be lying in bed, maybe resting, or being bored watching tv.If he's physically capable, they'll probably want him to regularly get up and walk around, otherwise all sorts of other issues might start due to being bed-ridden.

Why can't surgeons "fix" paralysis? | Complexity. We don't know enough about nerves to fix them in all circumstances.. Reattaching bits of your body doesn't always leave you with feeling. |
Why are eggs at the grocery store only white? Most home-raised chicken eggs I've seen are different shades of brown. | They come from Leghorns, the commercial hen of choice. The Leghorn is an inspired egg layer, they average nearly an egg a day and they're big and incredibly consistent. Price per egg on the production side is driven by the cost of feed and the number of eggs a year a hen can lay so the Leghorn is the champ of the comme... |
How does Adderall (amphetamines) calm down those with ADD/ADHD. It seems counter-intuitive that stimulants calm someone. Explain! :D | As an Adderall user, it's not that it calms me down but it helps keep me focused on the task at hand. Instead of, at the end of the day, having 20 tasks that are all half-assed completed I will actually accomplish something. I'm not saying that I don't still lose focus and start other shit but the Adderall will help re... |
The importance in the increase of NASA's funding | There are three options: publicly-funded space research, privately-funded space research, and no space research.

why can cheese be matured for years but when it's in a store it has a reasonably short use by date? | Because between the point where the cheese was maturing and the store, it was usually cut up and put in plastic, exposing it to the environment. As a result, other bacteria can get past the outer membrane of the mature cheese and start interacting with the yummy contents. In most cases, aged cheeses can be used well pa... |
Why is men's fashion so much more limited than women's? | In general, we have this cultural idea that beauty is a lot more important in women than it is in men. So it's not just fashion and clothing but all appearance-related industries cater mostly to women and therefore give them a much wider range of options, because they're taught to care a lot more about their appearance... |
why an airline ticket can cost less with a layover than leaving directly from that layover city | It's all about demand. There are probably far fewer people traveling from Columbus to Philadelphia so they need to set it at an appealing price. There are a lot more people who will leave Detroit for anywhere. The price of a flight, after base costs of fuel and taxes, are pretty arbitrary in that they're set by what th... |
Why do some religious groups (e.g., Shinto, Amish) rarely or never commit acts of terror, but other religious groups (e.g., Moslem) frequently do? | I think even in Christianity there are brutal exterminations as well as verses that support violence. the truth is that if a muslim kills group of people. ..he's termed a terrorist but if a jew or Christian does the same he's termed a murderer and so on .In addition the media has also contributed towards propagating su... |

Why CRT TV's have that line going through them when recorded by a camera | Someone may want to confirm this, because it's just an educated guess, but I think the frame rate of the camera is such that it picks up the crt scanning lines in the way we see it .. similar to how a helicopter rotor may appear to spin slowly backwards. |
"Hearing" my own thoughts | Our brains aren't split into two halves that deal with thinking and doing. If you think about moving your left arm up you will use the same part of your brain as you do to move your arm up, the only difference is that a part of your brain called the basal ganglion blocks this from actually happening. I can not give you... |
