Why is the "eye" of the storm so calm. Why isnt it the worst part because its in the centre | It's like when water's going down a plughole. When it spins, there's no water in the middle.

At the edges, you're moving much faster than if you just stand in the middle, beca... |
The science behind why I have the strong urge to yank the steering wheel, jump off high places and other stupid and dangerous things | This effect, called the High Place Phenomenon , is not entirely understood.

What came of the Occupy Wallstreet movement? Why did it end seemingly so fast and descrete? | Basically, because it had no coherent goals, and no ideological consistency.

Why are some NFL teams generally better than others over extended periods of time? Aren't new teams drafted every season? | New players are drafted not teams.

Evolutionary-wise, why did humans develop a fully functional language, whereas animals didn't? | Short answer. Brain. Long answer. They're doing fine without one and evolution can't plan so it can't go, "Wow, language is working great in humans so let's develop that in cats." |
Why is it impossible to film something in real life for virtual reality? | It would be possible, but you yould need a ton of 360° cameras and software that allows you to switch between each feed or even a super advanced program that stitched the feeds together, meaning you have a full 3D rendering of the room.

in America, why is traveling by train more expensive than traveling by air or bus? | From an energy perspective if all three modes of transportation were going from the same point A to point B via the same route the train should be cheaper as it's more energy efficient. One huge perk that planes have is that they can fly in a straight line to their destination where the trains can only follow their tra... |

What is net neutrality? And why it is good or bad. | Net neutrality was the concept that said that every website, regardless of the content or bandwidth requirements would allow the same amount of bandwidth and speed for every other site.

How can my prescription cost $400 at my local pharmacy, yet the same prescription cost $0 from a mail order pharmacy located in a different state? | It's how your plan is structured. Even if the cash price of the drug were the same your plan will pay less of that cost for going to your neighborhood pharmacy.

Why does string theory matter? | Physics, right now, is divided into two sections: general relativity and the standard model. To simplify it drastically, general relativity basically discusses the physics of really big things and the standard model describes really small things. The problem is, general relativity takes gravity into consideration and t... |
Why does it feel like you can't breathe when you get a gust of wind in the face? | When a fluid moves rapidly, its pressure decreases, thus sucking things into it. You may have observed this when your shower curtain clings to the stream of water from your shower. Similar effect happens here and makes it harder to breathe in air.According to [Bernoulli's principle], the faster a fluid is moving, the l... |
Why is it that after you say or type a word many times in a row, you'll begin to question yourself as to whether it's correct | It's called [Semantic satiation].

Why do people use AskReddit and eli5 subreddits when Google can usually answer their question? | I don't know, maybe you should Google that.AskReddit generally has more community input.

How is it possible to sleep for a few minutes, yet dream for what feels like hours? | Odd, for me, I sleep for hours, and it's lucky if I remember more than a couple of minutes of dreaming.The apparent passage of time from one's perspective is very subjective and dynamic. Time flows faster when we're happy, and slower when we are bored. If our brain is capable of creating the entire dream world, it's ea... |
What would happen if the Earth's rotation changed. For example the sun rises in the north and sets in the south. | The Arctic and Antarctic circles would expand to the equator. Summer and winter would be the same as day and night. The polar icecaps would be constantly shifting. |
If we could drill through the earth...and then jump in it...what would happen? | _URL_0_ This pretty much explains what you're asking.I have read about this a while back. Basically you would jump straight through and speed up all the way , and once you reach halfway you would gradually slow down again until you reach the other part of the hole. From there on you would have slowed down enough to lan... |
Why does pop-corn pop? | Popcorn is a specific variety of corn - most corn will not pop. What causes it to pop when heated is that there's a drop or two of water inside.

If I have 20 mb/s download speed, why do files generally download at only a fraction of that speed? | Make sure you are not confusing MB/s with Mb/s . Most speed tests and Internet Service Providers measure bandwidth in Mb/s , however some file downloads are measured in MB/s depending on what software you use.

Was scurvy actually particular to sailors? It seems like citrus wouldn't have been available to most of the lower classes | Scurvy is caused by a lack of vitamin C. Vitamin C can be found in peppers, turnip greens, cabbage, broccoli, tomatoes, peas, and other foods. A lot of those would be available to the lower classes at least some of the time.Citrus isn't the only source of vitamin C, it just happened to be a good one for ship-goers sinc... |
when one eye gets irritated, why is the body's reaction to blink both eyes instead of winking the irritated one? Is there a reason winking is a manual function? | Without going TOO deep it’s just an innate, automatic, “consensual reflex” to protect your eyes. When one eye blinks the other should too. When someone has an eye injury we usually patch it/cover it to protect it, that way your body’s automatic response to “flip out” and over-blink to remove the threat to its partner i... |
Internet network speed: What's the difference between "kbps" and "KB/s" transfer rate? | Little b, big B. Big difference. Little b = bit. Big B = byte. 8 bits in a byte. 10370 / 8 = 1296.25Capital letters are important here. "mb/s" should never be used, because it's ambiguous.

How can a decrease in the global price per barrel of oil create a negative affect on local, national or global economies? | Plenty of industrialized/first-world nations produce oil, so lowered oil prices means less profits for those industriesIf the return on money spent getting oil dips too low, thousands of people loose their jobs. As an aside, those people make ALOT of money doing it, and are generally giant assholes. So they have a hard... |
How does basic universal income work? | The basic idea is to give everyone a set income that they would first spend on housing/food/basic amenities, guaranteeing them their livelihood.

How Did Baby Boomers ruin the economy and housing market? | Well blaming it on ONLY them isn't necessarily true. Long story short: someone approved giving big loans to people buying houses.

When an episode of a series require several flashback scenes e.g. all scenes where people get slapped, do editors go back and scan all the previous episodes or do they keep some list beforehand? | To create a montage of clips where character A gets slapped, an organized editor could reference episode summaries or other tools to quickly locate those scenes. A disorganized editor might rely on memory and miss/forget a few. A truly awful editor might need to re-watch great swaths of the show to find the scenesThe e... |
Is a fat muffin top at your belly caused because humans wear clothes around their waistline? | Yes, but not by much. Your fat stores are all located in/around your hips/pelvic region, they swell and become distended due to an increase in volume of fat storage.

How can an igloo stay warm without melting? | It does melt a little bit. Heat is trapped on the inside, but on the outside, it is still very cold and kept frozen. All the ice the igloo is made of is in contact with more ice on 4 sides, and 1 side is facing outside in contact with very cold temps and wind. The blocks are also quite thick so the ice is better insula... |
Why do you instinctively gasp when falling? | I was told by a martial artist that it is the same reason they scream when they throw a punch or kick. It tightens up your core and gives you "extra strength". Why your body would do this instinctually is, when you hit the ground you are not a flimsy noodle that gets squashed. Not sure how true, just what I was toldbas... |
How do companies like Facebook and Dropbox get their profit? | Facebook has tons of ads and makes a billion dollars quarterly through advertising and promotion.> Facebook doesn't show ads or requires me to pay anything.

How is it possible for some childeren at a young age to enter college? | You don't necessarily have to finish all the grades to enter college. You can also take an entrance exam which determines if you have enough background knowledge, and then sometimes exams to skip prerequisites for courses. Lots of kids are accepted to community college before they graduate high school - my son took cal... |
How does a speaker work? | Many frequencies all sum to one wave through constructive and destructive interference. Think about the wave in air; the air can only be one pressure at a time, so no matter how complex the sound it results in just one waveform. |
Why do I feel like I need a shit after drinking coffee? | Some studies say coffee causes contractions in colon muscles. Apparently haven't been too many studies but I would say it's also combined with the natural time for most people to go #2. We could do our own study, next time trade your coffee for caffeinated tea or a Coke and see what happens :) we can at least see if it... |
If space telescopes are so powerful that they can see light years away,why can we still not see the surface of closer planets? | My eyes are so powerful that I can see a couple mountains from my office in Lexington Kentucky several miles away. However, I cannot read a sign on a shop window less than a block away. One must keep in mind scale_URL_0_ XKCD to the rescue. The core point is that planets are small, moving really fast and are spinning. ... |
When I pour water into a glass of ice, why does the ice make a crackling sound for a few seconds? | Well as you may know, water expands when it freezes. When you pour warmer water it warms the outside of the ice causing a temperature difference between the inside and the outside temperatures. While the outside of the ice is being warmed it contracts while the inside of the ice doesnt change much. This causes great st... |
Why it is perfectly acceptable to have people wearing only underwear in picture advertisements but we ourselves are not allowed to stroll around in just underwear. | Why do you think we're not allowed? A bathing suit has the same amount of coverage. As long as it is opaque it should be fine, though some cities enact ordinances otherwise. As far as private property, like a mall, they are free to set their own standards. They can kick you out for not wearing shoes even though it's pe... |
Is human knowledge just a tower of assumptions, each block reliant on another, that would collapse if a fundamental "truth" at the base was proven false? | Sure, if our Axioms were proven false the entire system built on that Axiom would collapse or at least take a heavy hit. Thing is that our axioms are pretty sturdy and are often self-defining. A triangle has angles adding up to 180 degrees. You cannot disprove that because any shape that has a different sum of angles i... |
Why is it so hard throwing an object straight upwards when lying down? | When you were a child you took a long time to learn how to throw properly, moving your body in just the right way. Throwing is actually quite a complex action, using lots of muscle groups, and if you try to throw in a particular way without having practiced a lot, for example with your non dominant hand, or lying down,... |
How do microwaves work? And why is that an empty container next to a container full of food will stay cool and the food gets selectively heated? | Microwaves use radio waves to excite the water molecules inside an item to heat it. Since the empty container has little to no water in it, there's nothing to excite and cause heat |
How does our body develop immunity against diseases such as smallpox after we recover from it. | > whats the mechanism for it? [Some basics on the immune system] Your body is constantly producing B cells covered in antibodies, which are Y-shaped proteins. On the arms of the Y shape, there are different shapes. They will react to foreign molecules, such as those on the outside of a smallpox virus . When a B cell wi... |
How are stock prices calculated? | A typical stock's price will change numerous times throughout the day, based on its last known sale price. Stocks are quoted in two different numbers, the "bid" , and the "ask" . When a transaction actually occurs, the exchange computer registers it, and that becomes the latest quoted stock price on your Yahoo or your ... |
What exchange rates mean? | It doesn't really matter if one is higher or lower. What matters is the change in exchange rate over time. So if country A to country B exchange rate was 2:1 last year, and today it is 1:2, then that matters because it affects prices of goods that are traded between those two countries. But if they stay relatively stab... |
What's going on in your head when you have a "deja vu" moment | During Deja Vu short term/current experiences are being written in real time to the area of the brain used for long term storage, and then immediately recalled concurrently.

Why does giving babies peanuts earlier on decrease the risk of them developping peanut allergy? | Parent of a peanut allergic kid here. Unfortunately science doesn't know yet the exact mechanisms that lead someone to develop a peanut allergy, except that certain genetic factors predispose one to allergies, asthma, and eczema For many years the medical wisdom was that early exposure before the immune system matured ... |
Why does an image formed by pixels on a screen remain sharp, when light tends to spread out over distance? | The image from the screen *does* become wider as you get away from it, the same way it does from a torch That's why if you and I sit a few metres apart, we can both see the same screen. However, unlike the torch, each pixel is generating light in a very tiny place. From that place, light is emitted in all directions - ... |
Why do certain shots hurt more and for a longer time than others? | The three main routes are intradermal injection, subcutaneous injection and intramuscular injection. Each type targets a different skin layer: Subcutaneous injections are administered in the fat layer, underneath the skin. IM causes painful bruising because the needle is going into your muscle. |
Garden centres and pet shops have dirt cheap "bird feed" peanuts. Why can't I eat these instead of regular grocery peanuts? | You can. I grew up in a pet shop family and ate tons of bird seed seeds and even dog treats. I would check the country of origin on the label though, as some countries may use pesticides that you want to avoid.Food products like seeds and nuts that aren't meant for human consumption may be processed in ways that make t... |
Why is it bad that the 85 richest people on the planet are worth nearly as much as the poorest 50 percent of the world's population? [Serious] | It's not bad if you take advantage of the situation and think smart. If rich people have more money then half the world you start a billionaire protection service, complete with drones/cyber-shielding/etc and military veterans. Sounds like they are gonna need it. Oh and if you do, make me a VP or something. Don't let a... |
As I am falling asleep, why do I see images and hear sounds that are almost like hallucinations, and how do they differ from normal dreaming? | It's called hypnagogia. As you transition from awake to asleep, you pass through a weird bit where it is possible for bits of dream to get mixed in with external sensations, and/or for lingering bits of external sensations to get mixed into your dreams. This experience of dreamstuff while not entirely asleep can make y... |
Where do our eyes focus when we close them? | The eye focuses on light, and thus when you close your eyes the muscle involved, the cillary muscle, relaxesI was taught that with the eyes closed they tend to focus at about 1 Diopter or about 1 meter from youI remember that when we were messing with our buddies during a summer-camp by opening their eyes in their slee... |
Why treads provide better traction than smooth surfaces. | If you are referring to car tires, a bald tire does have more traction but only when dry, street cars need the treads because it isn't going to have the ideal conditions a track car would have. |
How come there is so much money in golf? Tiger Woods is arguably the best paid athlete, yet no one I know watches golf, and neither has golf big stadiums like football. | It's about who the audience is. Advertisers and sponsors are OK with decreasing the number of consumers if they can reach a richer audience. Golf is more of a sport for the richer set whereas football is more of a sport for working class people.Endorsements, & sponsoships play a huge role. Also, I have seen Tiger Woods... |
When I call someone, why is the first ring always louder than subsequent rings? | This is probably due to sensory adaptation. When you experience something that triggers one of your senses multiple times in a row, the experience is less and less each time. This is also why you get used to smells. |
Why do the veins on my arms become less apparent when it is cold? But more apparent when it is hotter or I am doing physical labor? | This is part of your thermoregulation system. When it's hot, your body pumps more blood to veins near the surface in order to radiate heat from it. Likewise, when it's cold, blood is withdrawn from the surface to keep it warm. |
Why does "the big red car" sound better than "the red big car" in the English language? | Because adjectives have a specific order in English . The order of adjectives in English is > Quantity or number. > Quality or opinion. > Size. > Age. > Shape. > Color. > Proper adjective > Purpose or qualifier. As you can see size comes before colorBecause different languages have different adjectival orders. The rule... |

Why does adhd medicine calm people with adhd down and speed everyone else up? | ADHD medication does "speed up" the brains of people with ADHD; what looks like "calming them down" is really more like "speeding up the part of the brain responsible for staying focused."As a person who took Adderall for 6 years of their childhood; it seems like it calms down children but has the opposite effect on ad... |
Is being disgusted by fat people just social conditioning, or is there more to it? | It's a combination of biology and social condition. Biologically, we are coded to find attributes of the opposite sex that we perceive as an indication of fertility and ability to raise a child. In women that means wide hips , large breasts , and general fitness , and physical symmetry . In men that usually means physi... |
Do mosquitos know the risk they take when they land on us? | Mosquitoes in all likelihood don't even have a concept of death, so no. Their brains are incredibly simple so they can't even extrapolate that far into the future. |
Instead of aiding fleeing refugees, why not make them stay and fix their own governments/countries? | First of all, Canada is only committed to taking 25,000 refugees. That couldn't even take Rogers Arena, let alone a nation. For perspective, Assad has ten times that many political prisoners already, and the US government has released evidence that he tortured to death half that many people since 2011. Syria is an unwi... |
Einstein's Theory of Relativity and a phone call going across the galaxy | Ok, as simple as I can explain it. Time slows down the closer you get to the speed of light, but only from an outside observer's perspective. So, if I'm on a spaceship travelling near the speed of light and you're on a planet watching me fly by to you, time is passing normally and I'm in slow motion. To me, time is tra... |
Why don't razor/shaving cream companies push for men to shave leg hair? Wouldn't that increase their market and profits? | There is also a risk of a backfire.. If they push it too aggressively, then the brand may be seen as feminine by a large part of the target group. As you might have noticed, portraying a macho image with male-grooming items is seen as important in advertising.It's just a guess, but I imagine they've done market researc... |
Why do a lot of people(might be subjective) think Keanu Reeves is a bad actor? | His range of acting is said to be really limited, you generally know the general sense of his characters before going to a movie. Personally, I think he is the person for those roles. No one plays his type better than he does. I can't imagine anyone else has Neo, I know other actors would have their own variation, but ... |
How is the present defined with respect to the space-time continuum? | In relativistic physics, which events are simultaneous depends on the observer looking at the events. So every observer has their own present and if different observers are travelling at high speeds relative to one another they'll disagree about which events are in the past, present and future. |
how do zero acceleration and zero velocity work? | Yes, acceleration is when there's no change in velocity. Zero velocity is when there's no change in position . But velocity is a bit weird in that's it's kinda arbitrary. It needs to be relative to something. So it's perfectly legitimate to say that you are moving at 0 m/s, or 10000 m/s, as long as it's less than the s... |
Why can't I have a wild bird like a cardinal or a jay as a pet? | Being undomesticated, they retain the wild, primitive instincts of their velociraptor forebears. Eventually, the impulse to roam and horrifically mangle secondary characters without actually appearing in-frame will prove too much and they'll get loose. After that, it will only be a matter of time before they learn to w... |
What is the difference between "Equal" and "Stretch" tuning for pianos | In general it has to do with how far apart an ocative truly is .central A oscillates at 440 oscillations per second. One ocative in equal tuning would be doubled or halved that so the A above is at 220 oscillations and the one below is at 880 oscillations.

why is a fisheye camera lense typically used in skateboard videos? | The most important aspect of the fisheye lense is that it is wide angle. So much so that careful framing is not too important. Also, the wide angle minimizes jerkiness and vibrations. Then, you can have your cameraman chase after you while moving at speed, jumping and shit without needing a dolly or big steadicam rigA ... |
Fruit flies....how FAR can they be 'forcibly evolved' in a lab? | They 've been bred to the point where they weren't able to reproduce with other fruit flies. That's commonly considered a new "species". It would probably take too long to turn it into something very very different. |
Why does a processor, for computers, get so hot? How doesn't it just melt? How does a fan and a heatsink work so well? | There's an enormous amount of work happening in a tiny amount of space. Under load, CPUs use huge amounts of electricity, which generates heat. The heat in the CPU can be controlled with a fan because, while it's very hot, it's also a very tiny area. So the total amount of heat-energy that needs to be removed is quite ... |
If the vast majority of video cameras and websites support HD video nowadays, why is the porn industry still flooded with low definition videos? | My best guess would be that they want you to subscribe for the higher quality/full length content. Why give away your best product for free right? |
Knights and knaves logic puzzles | Lots start by seeing if person 1 is a knight? He said that both people are knights. If that was true, person 2, being a knight , would have to tell the truth. But he said that person 1 is a knave. There is no possible way for person 1 to be telling the truth. So if person 1 is not telling the truth, he's a knave. Well,... |
How do rush hour traffic jams form? | Traffic is like pouring milk through a funnel. If you pour more into the top than can escape through the bottom, the milk fills up the funnel and overflows. Only so much milk can move through the bottom of the funnel, and pouring more into the top doesn't make it move through any faster. But, a road is like a super lon... |
Why is the 1/4 mile stretch and 0 to 60 the benchmark cars are rated for? | The European standard for measuring acceleration is the time for 0-100 *kilometers* per hour. This is converts to about 0-62mph which was then rounded down, so both numbers are very similar and can be easily compared. The quarter mile seems to come from quarter horse racing ), but I figure that this is just a good dist... |
Why/ How are celebrities insuring their body parts!? And what does said insurance actually cover! | Celebrities do it because there are certain parts of their body or features that are important to the line of work they do or get people interested. For example, pornstar Kieran Lee insures his member for $1 million as his member is the only way he can earn an income thus if anything happens to it, the insurance compan... |
Why did George Lucas need an actor inside of R2D2? | Robotics in 1976 was primitive. The guy turned the top and made R2 wiggle the right way. This was way better than any robotics could have done without spending way more. I am certain that part of R2's personality and charm actually came from having a person in there doing some moves.Electronics, radio controls and actu... |
Do flightless birds still have hollow bones? | It depends on the bird in question! Hollow bones are the ancestral characteristic in all modern birds, but more interestingly they go back *much* further than the evolution of avian flight, right through to [theropod dinosaurs] and even [sauropods] ). Having evolved for reasons other than flight, there's no immediate r... |
