How do large sea animals leap so high out of water? | When you and I jump straight up, we can push ourselves upwards over the span of a few feet if we crouch down first. When a whale or a dolphin jumps, they can start off deep and get a "running start" towards the surface to build up speed. Humans can do this too, but only horizontally, which is why the world record long ... |
How it is possible that we haven't ran out of possible melodies in music? | The total number of possible melodies is finite, so we could theoretically run out of melodies, but it's a very big number. Define how long a sequence of intervals needs to be to be called a "melody". Let's say seven intervals, making the song eight notes long. There are twelve intervals, so 7^12 = 13.8 billion possibl... |
The reasoning behind the United States choosing to not ratify the Kyoto Protocol. | At the time, the US position was that since certain developing countries such as China and India weren't being asked to sacrifice more that the US shouldn't have to sacrifice either. |
What are the rational arguments that would convince average Americans that giving ISPs the right to control internet traffic is a good idea? | The best arguments I've heard is that if they're allowed to charge certain sites more then they'll be able to use the money to build out extra capacity to handle Netflix's traffic. Which is in theory good But that's not how it would work in practice. There's no incentive for them not to just pocket Netflix's money and ... |
Why commercial breaks have more volume than the shows on tv? | By law, in the US at least, TV stations and cable networks are required to play commercials at the 'same average volume' as the programs they accompany. The Commercial Advertisement Loudenss Mitigation Act was passed by Congress early in the decade and the rule has been enforceable by the FCC since 2012. The FCC's [Lou... |
Why can't the weather be predicted with 100% accuracy? | Greetings from your friendly neighborhood meteorologist: The short answer is chaos. The weather is physics, and the only way you can perfectly predict physical outcomes is if you can be sure of practically everything going INTO them. For example, the rise and set of the sun every day. We know what dictates that, and we... |
why does the Republican Party want less government intervention economically but more government intervention socially (and the opposite for Democrats)? Why isn't there a consistent "more government" party? | The Republican Party does not, categorically, want more social intervention--it is host to both libertarians and social conservatives, whose views widely differ. Some Democrats, for their part, advocate for some reduced forms of intervention as well , but the party also has a conservative faction. Your view of the part... |
What causes an Ovarian Cyst? | There's a large number of things that can cause a cyst, which are, simply put, an abnormal sack of fluid that collects and grows. Most ovarian cysts are benign, but they can also arise as a secondary effect from other conditions such as endometriosis. Cysts can also occur from menstruation where the follicle containing... |
Can someone explain the differences in tropes and style in romance ( novels, shows, etc.) through different time periods. | I'm gonna go on a limb here and try to explain part of it. If you look at the beginning of theatre then the Greeks divided it into two categories. They had comedies and tragedies. The comedies were funny and light while the tragedies had sad endings where everything goes to shit, like Oedipus . This is pretty much the ... |
How differences in how we fall asleep affect the quality of said sleep? | The short answer is the circadian rhythm. When you feel tired is not only determined by how long you have been awake but also by the time of day. Humans have been sleeping at night for a long time, so your brain will usually pick up on clues from the environment, such as darkness, and tell you to go to sleep. So you ha... |
please ELI5 ... why is the headrest part of most car's seats designed to be so angled forward? | Headrests aren't there to rest your head against, but to protect you from whiplash or worse if you're in an accident. When a car decelerates VERY quickly and you are wearing your seat belt, then your arms and upper torso will fly forward very quickly. The three-point seat belt keeps you from flying through the windshie... |
Where does the color in food go once we consume it? | Remember when you played with play dough as a kid. If you mixed all the colors up you just end up with a big brown lump? |
Why are the Israelis and Palestinians in a conflict? | Century? Thousands of years. They trace the fight all the way back to Genesis. God promises Israel to Abraham and Sarah's* descendants. Abraham and his wife are in their 90s. She can't have kids so she tells him to sleep with one of her servants. He does and they have a kid, Ishmael. God says, "No, dummy, I said with y... |
Why do some fruits have pits or seeds with cyanide in them? | To discourage animals able to digest the seed from eating the seed. In this way it is more likely to have the offspring survive, and thus reproduce themselves. |
Why do cops put white towels on the shoulders of saved victims in crimes scenes on the movies? | I don't know about white towels, but ambulances have foil heat blankets that are used to treat hypothermia and are also used for shock. One of the symptoms of shock is cold, clammy skin, so presumably these blankets, which can trap body heat, help with that. |
How does one get from observing the present universe to deciding how things must have happened in the past and how things are going to happen in the future? | I'm guessing you mean Big Bang. There are two big pieces of evidence to support that theory. We look at a galaxy that is some distance away and we see it going away from us. Then we look at a galaxy that is twice the distance, going twice as fast. Then we look at other galaxies and we see that they have the same patter... |
Why do night vision cameras cast a shadow? | Many night vision cameras use an infrared lamp to illuminate the scene being recorded. You can't see that light, but the camera can. Hth. |
Why is it that the hair on our head grows without a limit, while the rest of the hair on our bodies only grows to a certain length? | Because your head hair does grow to a limit. It's just a longer limit than the hair elsewhere |
East/West Berlin divide still visible from space due to different lightbulbs | East Berlin uses sodium vapor lamps for street lighting that look yellowish, West Berlin uses mercury vapor lamps, and those produce blue-ish white light. Both are commonly used for street lighting. Sodium is more efficient, mercury produces a better light spectrum.I'm guessing that the difference is the types of stree... |
How to calculators randomly generate numbers? | computers and calculators, assumin no input, cannot generte random nunbers. what the do is invoke an algorithm that generates what appears to be a uniform and random series for all purposes. wait long enough and the patter eventully emerges, be it a million digit long.They take the time in microseconds: let's say it is... |
Why do news channels care so much about who breaks the story now? Doesn't the internet make everything break at the same time? | You want people to watch your channel instead of your competition. If you have a reputation for only getting the story after everyone else, people will be less likely to watch your channel. Sure, the fastest way is to get the info online, but the majority of people who watch news channels do so because they don't want ... |
Why does toast bread keep all the cheese in while normal bread lets the cheese ooze out? | I understand your question. In lots of places in Europe, they have their usual bread, which most of North America would see as fancy bakery bread. It's either a sourdough, a fluffy white loaf or a dark rye. What they call "toast bread" looks what a North American would think of as regular bread. A pre-sliced loaf that ... |
How is it legal for to pay someone for sex as long as you film it and call it porn, but prostitution is illegal? | Check [this] out. Basically, "the distinction is that, at least in theory, porn stars are paid to act and prostitutes are paid for sex." Sex is a part of a porn star's 'role\' - you could argue that they're being paid to act, not to have sex specifically, and therefore they're protected under the First Amendment.In the... |
How did the Tupac hologram work ? | firstly, it wasnt really a "hologram" as we would think of in a science fiction movie or something like that. it is an illusion technique called "pepper's ghost." the wiki entry is pretty good on it:_URL_0_ |
Why are ancient ruins underground? | Not all of them are. Plenty of ancient ruins are above ground. That said, the simply answer is detritus builds up. In old forests you are walking on layers and layers of decomposing leaves. Every year new layers of leaves, wood, mulch and other detritus are added while at the same timethe lower layers slowly decompose ... |
Why do pictures of far away galaxies appear so crisp and beautiful but recent images of an asteroid near earth is grainy and of poor quality | The difference is like: * Asteroid looking at a golf ball, at night, located across the street from you. * Galaxy looking at a spot light, at night, pointed at you from a block away.The galaxies are really, really, really, like f-ing huge. They are also quite far away, but as it turn out a 1-mile wide asteroid in our c... |
We see meteor showers around the same time every year.I would assume they would come at different dates as we rotate around the sun. How are they predictable? | They occur when Earth passes through a large collection of space rocks. Since we go around the Sun on a round path that repeats every year, we know we are going to be back in that spot on about the same dateComets leave debris in along their orbits. The earth intersects these orbits at about the same time each year. Th... |
How come that sugar has such an intensive taste but does not smell at all. | Your tongue has sensors for very specifc things: salts , sugars , bitter compounds , certain acids , and lastly, glutamates None of these 5 flavors rely on smell, usually because their presence would be very hard to detect most of the time . because these flavors are hard or impossible to smell, they are detected by th... |
If you built a house several miles away from anyone else, is anyone (or any government department) obligated to provide you with electrical access? | It kind of depends on how they are regulated. Here in Sweden, for example, the power companies operate under concessions. One of the concession rules is that the power company must connect a new customer *who is willing to pay the actual cost*. That means, basically, that they are legally forced to give you a reasonabl... |
How, on a technical level, did Carnegie Mellon (reportedly) help the FBI unmask Tor users? | Here's my lame attempt to take something uber complex to ELI5 level: You know those card trick games where the guy mixes up the cards really fast and you're trying to guess which one it is? That's kind of like Tor. Tor gets a bunch of people to volunteer to be relays. When a request comes in, they pass it randomly amon... |
What determines the speed limit of a road? | For traffic engineers it's the 85th percentile. In other words there is an assumption that 85% of drivers will drive at safe speed for road conditions. Speed studies are done, and this determines the speed limit. Unfortunately, the traffic engineers recommendations are often ignored by politicians, who set speed limits... |
how foodstuffs can sit on shelf a long time and then must be refrigerated after opening... is it just exposure to air that flips the switch? | Right on, and exposure to bacteria. Moisture without oxygen in a sterile environment won't generate bacteria. Once opened you have all three, by refrigerating you actually just slow the enzymatic breakdown and reduce the suitability for bacteria to grow on the food", 'Yes. Once the seal is broken, the contents are usua... |
Why can't we tax everyone the same percent? | There is literally no government policy anywhere that *nobody* would complain about. In this particular case, it makes little sense to tax people who are already on government assistance . |
How a Jeep is able to climb an almost vertical incline with not much trouble? | a combination of low gearing, low center of gravity, and engine location. the engine being in the front means that the weight helps hold the front end of the jeep down, making it far less likely to flip while climbing. the low center of gravity also helps prevent flipping in the same way. the low gearing allows for ver... |
Why is it that transplanted organs only have a short life span once transplanted? | Primary reason is the person's immune system attacking everything that is foreign in the body, including the cells of organs that don't have the exact genetic markers that the immune system recognizes. So in a transplant situation, they have to match the blood type between the donor and the recipient, and it helps if t... |
What happens to someone who does not eat vegetables at all | Are they being replaced with anything? You could go into a severe vitamin deficiency, which would have different effects based on what vitamins are deficient. Also you could go into a calorie deficit and lose weight.

does drinking chocolate milk give the same benefits as drinking regular milk? | The normal positive aspects of milk will all be in chocolate milk.The downside is that chocolate milk usually has quite a bit of sugar added to it. Edit: and as for milk with chocolate cereal, it depends entirely on the cereal. You'd just get bits of the cereal leaking into the milk, and I can't see that being any diff... |
How is the maximum load of truss columns calculated? | The amount of load a column can safely hold is principally based on the material,the geometry, and the nature of the load. The material has a certain strength properties. Each material has a certain allowable stress before failure . Also each material has stiffness properties, meaning the amount a material deflects wit... |
At what heights do falls become dangerous? | There are a lot of variables in that question. People have fallen and died from a standing positionIt depends what part of your body hits first. However, falls from more than 10 feet in adults and falls from 2-3x the height of a child are considered severePeople have died from falls from standing position. It depends o... |
What this Tesla Model S thing is about? | 1. A New York Times reviewer wrote up a description of a trip he took in a Tesla car. He described instances where the car didn't get as much mileage as Tesla claimed, and that at one point the car ran out of power and he had to have the car towed. 2. The head of Tesla called him a god damn liar 3. The reviewer publish... |
How durable are pandas? | Like all bears, pandas have ridiculously large and thick bones which make them very durable in general. In addition, bears also have thick layers of fat which can absorb impact, as well as dense outer hairs which provide protection. These attributes combined with their huge muscle mass make pandas and other bears essen... |
How does crop rotation work? | Crops have different effects on the underlying soil. Vegetables tend to be taxing on the soil because they're grown really densely, they need a lot of nutrients, and they don't leave behind deep root systems to help replenish the soil by decaying. Legumes harbor nitrogen fixing bacteria in their root systems, so they a... |
why did the SpaceX exhaust trail (or what ever that was) stay illuminated for so long? | It was because of the time of day. While it was night down on the ground, the sun was still shining 100km up in the sky. It was so bright and so big because the exhaust contained a lot of water vapor. When you burn any fuel containing hydrogen, it combines with oxygen to create water. In space, that water-containing ex... |
Why aren't there automatic transmission motorcycles? | There are, they just aren't popular. Also, scooters are a thing. Automatics cars are more popular than manual , because we are lazy and don't like to swift and like to always have a free hand. For motorcycles, it's different, you almost always want two hands on and shifting is much more simple, not many people are text... |
How can someone see practically all you've done on a computer, even after you've deleted it, but recovering a phone doesn't always find everything? | If you delete something, it's only moved to the trashbin at first, where it's still 100% intact. If you delete it from there, you only tell your OS to clear the place. It basically makes the area on the drive available for being written over, but it's still there, as not every single switch is reset. Only once everythi... |
Why is it far easier to run up multiple stairs than down multiple stairs? | Actually I think this has to do with the mechanism behind climbing and falling. When climbing, you are working against gravity and have much more fine control over how much energy and power is needed to be supplied to your muscles to overcome gravity and attain the speed you desire to go up the stairs. When going down ... |
Is there a word, in any language -- that describes the deep, sinking feeling of knowing that life is short, and we're going to miss out on so much... | Existential dread. Plenty of philosophers in lots of languages have discussed that feelingTorschlusspanik - Literally, gate closing panic, but meaning the feeling that aging is limiting our optionsThere's a phrase in Japanese that might capture the feeling you're taking about: mono no aware.

what's the difference between .com and .org and .gov and .net and etc etc | Different rules apply to each TLD . ICANN is the organisation that runs the show, they decide what TLDs should exist and what rules or sub-organisations should govern them. .gov is a good example since as you guessed, it's restricted to use by the US Government. ICANN will not allow anyone else to register a domain end... |

Plasma, in the electrical sense. Why is it its own state/phase? | Plasma forms when you heat up a gas to really high temperatures. The electrons get ripped away from the atoms due to their high energy. This is called ionization. This makes plasma highly electrically conductive. Plasma is its own state of matter because its properties are so fundamentally different from a gas, in the ... |
What causes our muscles to feel weak when we are nervous/ in a high tense situation? | When you are stressed, you're body reroutes blood away from your limbs to supply your brain and other areas. The lack of blood can give you that weak feeling.Basically your body is continuously pumping out the stress hormone. The stress hormone is a stimulant, and being exposed to it for long enough can cause you to fe... |
Why is it that when ants or other bugs fall from the ceiling to the floor they don't die/can still walk, but me falling from a short height could break my legs? | Square cube law. They don't have nearly the volume per unit of surface area you do. So assuming approximately equal mass per volume, the ultimate force generated by the same fall and stopping with the same negative acceleration will be much higher for you because of the increased mass. F=ma Also chitin is quite a tough... |
Why people lost all their money in bank failures back in history? Did they have no insurance or other securities? | Insuring bank deposits is actually a fairly recent thing - back when the Great Depression started, your money in the bank was only backed up by your trust that the bank wouldn't fail. Which is why there were runs on the banks when that trust ran out - if the bank went under, your money was gone. In the US, the FDIC was... |
How do we get pictures of North Korea if North Koreans are forbidden from the internet? | Under the right circumstances people can get in and out of North Korea.

In children this function is still developing and sometimes it doesn't turn off all the way or at... |
Why is everyone against a one world government? | Because the needs and wants of society vary greatly depending on the region you live in, climate, available resources, opportunities, culture there's very few laws and policies that you can blanket across the world and make work.Because they fear other cultures controlling their own, or other people/cultures getting we... |
Why do Indians bob their heads forward and backward when they talk? [FIXED] | The culture is different in india. A left to right wobble means "I agree". If they sort of bobble their head in a circular motion it means they are listening. If slow its friendly if fast its more like "I really understand"The head bob is just a gesture. It sort of means "ok" or "if you say so". You can think of it lik... |
If Mary was a virgin (and had thus never 'known' Joseph), why does Matthew 1:1-17 explain the lineage from Abraham to Joseph as the Genealogy of Jesus? | The lineage was to establish Jesus\' royalty by identifying him as a son of David and heir to the Kingdom. It was not meant to establish strictly biological descendency. Notice that it does not say that "Jacob begat Jesus." It specifically says that Joseph was the husband of Mary, who gave birth to Jesus. *Right after ... |
Why do some companies or sites pay for annoying pop up ads when they only make us angry and less likely to buy their products? | I can only assume these ad bring in a sizeable return. Businesses don't play around especially if it would only serve to ruin their reputations - but if something makes them money then they clearly wouldn't be competitive if they didn't take advantage of it.Even though they anger us I think those ads are still somewhat... |
Why do we feel the urge to keep throwing up even if there is nothing left? | It's because of the physiological mechanisms involved in throwing up. When you first start, it's in response to the body trying to expel something. The muscles around your stomach contract and squeeze it to propel the contents out . After a while these muscles start spasming despite the fact that the stomach is empty, ... |

The cos... |
How can a plant which has always been an indoor plant and never been outdoors suddenly have ahids or gnats? Where did the bugs come from? | Aphids are small enough to get through window screens and can be windblown onto screen from nearby plants, and most houseplants are kept near windows. They can also hitch a ride on you when you brush by aphid-infested plants then go inside. Most gnats seen in houseplants actually come from the soil, their larva feed on... |
Why does hot water (or heat generally) clean better than cold water (or cold generally)? | It's all about the chemistry. Heat is a measure of kinetic energy, so hotter chemicals are moving faster. In most chemical reactions adding heat will speed things up as the faster moving molecules will collide more often and therefore are more likely to react. Because of this, hotter chemicals have a higher reaction ra... |
Why did the FBI publicly release the information about Patraeus's affair? Isn't that part of his private life? | If he has something he wants to keep secret, that's an opportunity for blackmail. And blackmail is a big concern when you have access to top secret information. By making this information public, they remove a potential security risk, because you can't blackmail someone over something everyone already knows. Damage to ... |
How is the quantum world random yet the world we know predictable? | The quantum world is random in specific, but predictable on average. An example of this is the tossing of coins; no single toss can be easily predicted, but if you toss a coin many, many times, you can bet that it will land on heads very close to 50% of the time. When you put a few things that are predictable on averag... |
How does gravity affect time? | More gravity makes time go slower. The reason stems from two observations. **The speed of light is always constant, no matter who measures or where it is measured.**. One important result of this is that time and space will change with speed. Since speed is distance *divided by* time, the only way to keep the speed of ... |
How are time statistics calculated? I.e: every 20 a kid dies and stuff like that. How accurate this kind of numbers are? What is the time interval used for sampling? | It's not literal It's just an average based on totals over a total amount of given time Like if you knew in 1 year 12 people died from auto erotic asphyxiation the you would say that 1 person dies from it every month. Wheras the reality might be that they all died the same day at an auto erotic asphyxiation anonymous s... |
Why are some people naturally talented with maths? How does it happen? | I think this gets in to a nature vs nurture situation.

Or just lots and lots of practice |
What would the United States look like today if no humans have ever explored the land? | A hell of a lot of Buffaloes and Wooly Mammoth's would be roaming around. The Eastern US would have more forest than it does now. |
Why do cuts burn when you put hydrogen peroxide or rubbing alcohol on them? | The chemicals in rubbing alcohol when applied to an open wound activate the same nerve receptors in your skin that let you know that a flame is hot, giving you a burning or stinging sensation. 🔥 |
What objective reasons explain why some people can hold their liquor while others can't? | Practice makes perfect. This does not just apply to tolerance, which indeed would be much higher in someone who drinks daily as opposed to yearly.

I'm teaching myself to sing, and I'd like to know why my throat hurts after a short while of doing it. Also, how do I stop it doing this? | I'm pursuing a BA in classical vocal performance currently. Almost all vocal fatigue is due to muscle tension when you sing. Do you feel like you are straining to hit most of the notes? If so, the song may be in too high of a tessitura for your voice type. By your username I'm assuming you're male; a lot of pop and roc... |
Why is the post-WW2 50s decade considered the quintessential time period for defined gender roles when throughout the 40s women were in "men's" roles for the first time? | Because after the war there was a push for women to go back to traditional roles, this didn't fly. So women have been fighting to gain equal footing as men in career roles ever since. |
why window tinting is black instead of white | sane reason sunglasses are tinted dark or a color instead of white. It aborbing the light prevents it from coming in. Also if it was white it would reflect on the inside too. Possibly making glare which is opposite of the point. Depends what is trying to be achieved - for 100% privacy a mirror tint is effective but thi... |
Why do they worry about rocket ships burning up when returning through the atmosphere from space, but not going to space? | A rocket shop starts at earth at standstill and speeds up to get into space. The rocket ship is not going really that fast in the sense parts of the atmosphere. When a rocket shop returns it has orbital velocity, aka is going really fast. To slow down it actually uses the atmosphere. With terribly big shoes out enters ... |
Types of UK visas and what they require. | Go to _URL_0_ all the information is there. Since you're on a tier 4 I'm assuming you're a student or have a post study work visa.

Why does the US have so much more aircraft than any other country? | One of the main tactics used by the American military relies on overwhelming air superiority. Ground forces discover enemy fortifications and locations, and call for bombing runs.

Why does folding a piece of paper both ways help to tear a straight line? | Folding paper weakens the bonds at the fold. The outer bonds are stretched more, so folding both ways weakens both sides at the crease. When you tear, the rip follows the path with the weakest structure which is usually the crease. |
why wireless devices/electronics can't be used in an airplane below 10k feet.. | Previously the FAA was worried that the small EM field generated by electronic devices could introduce interference to an airplane's internal electronics. This was well before shielded everything on these planes. Recently the FAA has come out in favor of consumers, saying they are going to recommend the allowance of us... |
Is Africa as unstable as the media portrays it to be? | Africa's a pretty big place, and the experience can certainly vary depending on where you go. Blood Diamond was set during a civil war in Sierra Leone, so the shitshow factor is going to be pretty high in such a situation by default. If you went to some place like Nairobi, Cape Town, or Johannesburg, it'd be more or le... |
How do American street names work? | Pretty simple, actually they are probably the same as the UK. The examples you mentioned "[street x] and [street y]" are cross streets. They are saying "at the intersection of Raven and 42nd". All our streets have 2 parts, the name, like Raven or 42nd or Main or what-have-you, and the postfix, which is usually somethin... |
What happens when we crack our knuckles? | The fluid in your bursa sacs are moving, and quite quickly at that. Sudden movement makes the popping sound.Like you're five: Look at your fingers.

How come I do not feel hungry in the morning if I don't eat breakfast, but if I do, I find myself wanting something to eat or drink. | It's actually kind of simple really. If you don't eat breakfast, you're body looks to other ways to begin fueling itself.

On some... |
why don't hockey teams hire a 500 lb. goalie to block the whole goal? | There is a sports science episode covering this. It basically boils down to 1)It does not cover the whole net. And with the assumption that a 500lb guy isn't too athletic, the open part of the net will just be free goals. Also regulation sized protective equipement does not cover a 500lb man. |
How do new, unpublished writers ensure that their original work is not copied/stolen by the publishing house they give their work to consider? | Copyright protection, unlike patent protection, exists automatically to protect a work.

why the news doesn't report on suicide (unless it's a celebrity)? | Because comparatively few people care. It is not a story that has an effect on a significant number of people. |
Why do game developers make exclusives when it limits their audience so much? | Usually because that console manufacturer publishes the game for them. For example ThatGameComapny made really odd and out there games that a big publisher wouldn't likely publish, for fear it wouldn't sell well enough to be worth their time. So Sony approaches them and says "We will publish your game, market it, and s... |
