How does someone have a "Natural Talent", where do they get it from?? | Natural talent isn't so much talent in a specific thing. It's talent in the micro-things that make up that thing.

Why heroin in the UK needs lemon juice to dissolve it but US heroin doesn't | Like many organic compounds, heroin can come as a "freebase" form and a "salt". It refers to functional groups on the molecule that can be protonated . Many of these compounds have low solubility in water, but when the base is protonated it gains a charge, and becomes much more soluble in water. So if your compound is ... |
Why is it that once pubes are shaven, they begin to grow back immediately, but once they are at a certain length the pubes stop growing? | All hair is similar in this respect. The hair grows at a fairly constant rate, but is programmed to stop growing and fall out, and allow the follicle to produce a new hair after a certain time. So the length of hair is dictated by how much it can grow before the follicle drops itDo they really stop? Or do they just slo... |
If there's no way to reach trapped miners, how do rescuers know they're there? | ELI5: No mining company is going to send people into the Earth without knowing: A) Where they're going B) Where the explosions will be C) What personnel are going and who they are D) Detailed map of the mine and it's ventilation shafts If you know where they are, drilling boreholes isn't the hard part, since that's wha... |
How is it that my satilite TV can play/record multiple HD channels at once and with no wait, yet my DSL can barely stream one video? | The bandwidth of your DSL is limiting you. HDTV channels that you can pick up on a "bunny ears" antenna run at 19.4 Megabits per second. You will be lucky to see **10%** of that speed with your DSL connection. Satellite receivers using the latest compression can stream [46+ Mbit/s] per transmitter, and the satellites h... |
What would really happen if bees went extinct? | I think they're major pollenators for almost 90% of our grown food. Without them things don't grow. We could find another way but it would be costly, not to mention all the other plants that would die besides human food resources. Anything like lumber and cotton would become exponentially more expensive too. |
Can somebody help me in correcting these sentences? | I think some context would help a lot. Given the rape survivor stuff, I think your first one should probably be "I never felt comfortable around him." Or "he always made me feel uncomfortable." Like, this is about that creepy vibe that a child molester gives off by being too close or touching in the wrong way, not abou... |
Why do older guys' eyebrows go crazy | Forget the eyebrows. I can deal with eyebrows. What I want to know about is all that growth inside the ears! |
Why is it that dogs can't eat chicken bones, but coyotes can? | Dogs can eat raw chicken bones. When chicken is cooked, the bones become brittle and prone to splintering. This is what creates the potential hazard for our dogs. They can cause a perforation in the esophagus or stomach. Dogs on raw diets eat chicken, bones and all, on a regular basis. Coyotes don't tend to dine on coo... |
How do websites like G2A, sell games at cheaper prices and still make money? | Fraud. Stolen credit cards are used to buy the keys, the keys get sold to third party websites who sell them to consumersWhen a game releases its not the same price all over the world, simply because you cant charge the typical American 60USD price in a place that has far less than the average American pay. People buy ... |

Why does Reddit hate Israel so much? | It could probably be ascribed to the demographic of redditors. Young. Liberal. Not foxnews or funamentalist christianA shill is a fake account that is used to manipulate public opinion.

Why does the "morning sickness" associated with pregnancy occur frequently in the morning? | 'Morning' is just a catchy term. It's all throughout the day for some. Some women have a rare severe form where she had to be hospitalized. It blows. I was sick well into 2d trimester. Many women..no side effects at all. And each baby is different. It's annoying. 2 boys and each pregnancy was different.My Dr told me it... |
Why don't manga characters look Japanese? - | Animated characters are rarely meant to "look" like any specific people. That specific movie is made with an art style that is fairly typical to Japan. Various features are exaggerated, like hair and eyes. Really, making one or two things exaggerated is a great way to easily and quickly differentiate characters. Good c... |
Where do studios store copies of movies that are completed, but not set to release for another year, such as Hunger Games MJ Part 2? | The editing house has it, the producers probably have a few copies that they've screened, depending on how far along it is.Studios own hundreds of secured servers that are guarded and copies of the movie are monitored and tracked to prevent leaks. |
How can websites like hotwire and priceline get you cheaper arline tickets and hotel rooms? | It is beneficial for airlines to fill empty seats and hotels to fill empty rooms, rather than to leave them empty.

This allo... |
Volts, ampers and ohms. | Volts is how much electricity you have, amps is how hard the electricity is pushing, and ohms is the unit for how well a substance resists the flow of electricity. |
What does Jagermeister taste like? | The most notable taste is "black licorice". It's not exactly such, but the Jagerbomb bomb-shot is near spot-on. Hell, it's close enough that it makes Red Bull have a somewhat bearable taste.Kind of like Licorice but nicer . It's a little bit sweet and the taste of alcohol is not very strong, which is why people tend to... |
What is all the controversy surrounding 'Rush Limbaugh'? (UK) | watch it for yourself. It'll explain everything for you. [Here's Sandra Fluke's testimony,] as to why women should be allowed the hormonal pills to be paid for by insurance instead of forcing women to pay out of their own pockets. **TL;DR:** It's not just for sex, but also for a whole range of diseases, and general eff... |
How does Saturn maintain such uniform patterns on its disks? | Saturn's rings are inside the Roche limit. That's the minimum distance a moon can orbit a body without being torn apart by tidal forces. Once a.moon gets closer than that it will break up and form a ring system. Initially it will be chunky and have lots of rocks of different sizes, but over time the larler rocks will g... |
How does a Tsunami actually kill you? | Buildings are good. In general, you want to be in something sturdy enough to remain standing, but more importantly, in something high enough that you will be above the water.

Why is anything to the power of 0, 1? | If you rewrite the exponent of some number N to the 0 power as a fraction, the numerator and denominator are equal, and therefore it is equal to 1. take /, this is equal to N^. To get N^ to equal N^0 , x must be equal to y. /=1 = N^=N^0 When you increase the exponent, you multiply. When you decrease it, you divide. 3^2... |
Why are judges, particularly those in the SCOTUS, able to have biases or leanings? How does this equal a fair trial? | Supreme Court justices do not preside over trials. They consider disputed legal issues and make decisions which set binding precedent for lower judges, like the ones which *do* preside over trials. For example, the Second Amendment tells us that “ the right of the people to keep and bear arms shall not be infringed.” T... |
If breeding endangered animals in captivity is so difficult, why don’t we use methods such as IVF? | To a large extent it seems to be inertia. There is a lack of experience and understanding of how to perform IVF in other species. We know a lot about how best to do it in humans, not so much in other animals, because we've never had much incentive to try. Eventually conservationists will embrace IVF for critically enda... |
Why do old women (40-50+) usually have this shorter hair, whereas younger have long hair? | As people age, their hair may thin out as well.

Also, hair can become more brittle and thin with age, making it more difficult to grow long ha... |
How do Formula 1 cars produce such an iconic sound? | A very basic answer: a relatively small engine, producing huge amounts of power, with no sound restriction, and then running at well over 10,000 rpm. Where most engines would be exploding, formula 1 are just getting started, and redline near 20,000 rpm. |
The difference between Calvinism and Arminianism. | ELI5: Calvinists believe that everyone is going to hell *unless* you're one of the lucky ones that God chose to save ahead of time. Arminians believe that God gives you the chance to choose him and be saved or to deny him and go to hell. In other words, Calvinists believe in predestination and Arminians believe in free... |
Why do squirrels often not know to run away from the car coming toward them, but if a person approaches they get away just fine? | Cars are going so fast that many animals do not think they are going to stop and eat them. Similarly, humans look like a predator and are clearly big enough to eat them if so inclined. We're a lot more scary than a car. |
H.R.2768 - To cancel public debt held by the Federal Reserve System and to lower the public debt limit by $1.6 Trillion. From Ron Paul | "How do we owe ourselves money and what would happen if we just chose not to pay ourselves?" Technically we do not owe ourselves. The Federal Reserve does have the name Federal in its title, but is not associated directly with the US Government. The Federal Reserve is a privately run with a board of Governors. We borro... |
How do people remember they have forgotten something without actually remembering the things/ideas etc. they have forgotten | Forgive the tongue-in-cheek response, but they don't. If they forgot something, they no longer remember it, and if they remember it they have stopped forgetting. Semantics I know. Ok more seriously now, memories are made by specific patterns of neurons firing in the brain. Each memory has its own unique pattern of neur... |

What exactly causes one to develop a phobia? | Not a scientific explanation, but I have a fear of when initiating a phone conversation, especially a stranger, but even friends.

Why is it theft if I accidentally walk out of a store with an unpaid for item, but if a store accidentally charges me twice for the item its considered an accident? | It isn't theft if you accidentally walk out of a store without paying. Theft requires the specific intent to deprive the rightful owner of possession. Meaning, you have to know and intend to take the item. If you walk out accidentally, that isn't theft. If you later realize you forgot to pay and keep the item, now it's... |
How did fire arrows not extinguish themselves when they were fired? | because the film team makes sure the wrap is dowsed in gasoline or some other accelerant before they're fired. fire arrows weren't actually used in history. it was made up for tv/movies.They did. Fire arrows in the sense of literally just being a regular arrow but on fire are essentially a myth. |
Why do our nails keep growing? Why dont they stop? | Nails = Claws. If we were still swinging from the trees, they'd be getting broken and worn down from use, thus they need to keep growing. In our case, we've evolved past the need for claws, so they're thin and pretty much useless as anything but a decoration but they're still part of us and thus, they keep growing. Sam... |
If you have solar panels installed at your home | There are a number of different ways you can use solar panels. One way is that you are completely off the power grid, so you also need batteries .

How does us gov make money on war on drugs or do they? | It's not that the government makes money. They *spend* money. A *lot* of money.

If a dentist makes money off people with bad teeth, why would I use toothpaste that 4 out of 5 dentists recommend? | When I was a kid, my dentist had dentures. He had become a dentist because he wanted to help other people take care of their teeth, since no one had taught him as a kid to take care of his. I've never met a dentist who was happy to see someone with a mouth full of cavities. |
Why does it hurt more when you are cut with a dull knife than it does when you get cut by a very sharp knife? | A sharp knife makes a "clean" cut; none of the skin tears or rips, it simply separates the tissue neatly in a thin line. With a dull knife, however, the cut is much less clean. Skin catches and tears, so the net damage is much more severe and spread out. Think of a pencil. If it's very sharp, it draws a very thin line;... |
How can you be below sea level and not underwater? | Go somewhere that is 100m above sea level. Dig 200m straight down. Congratulations, you are now 100m below sea level! That's how places that are below sea level work, except that most of them are valleys that formed naturally. |
How can you tell if a diamond (or any gem) is genuine? | Most commercial diamonds now are laser-inscribed with a GIA serial number, which can be tied to records that authenticate the diamond. I assume this is also done for other precious stones. You can see this serial number under 10x magnification if you know what to look for.With diamonds, there are devices that can test ... |
Why can it feel cold when the sun is out and the sky is clear? E.g. a December morning | Because the axial tilt of the Earth is causing sunlight to strike one hemisphere at a higher angle. This means that less energy is striking any given part of the region. Think of it this way. Point a flash light straight at the wall. X energy is hitting the wall in that circle. Now, tilt the flashlight at an angle. The... |
Who owns the banknotes in my wallet? | You have something called a Central Bank in countries/regions. They are the ones that actually print money and sell it to the government or banks, which in turn ends in your hands.You do. It is a crime to destroy them though.

Who were/are the native inhabitants of Britain/Ireland? | The Celts were one of the dominant ethnic groupings in the British Isles before the Romans arrived -- we know this for a fact because the Romans documented this.

Why are software development tools freely available yet photo and video editing software prices so high? | There are free options for photo editing as well. GIMP is widely popular. Why are there no free ones? Because programmers that write code for you without asking for anything in return are angels. And beggers shouldn't be whiners. |
How come when you spin a glass/bowl with water and ice cubes in it (or anything really) the objects and liquid don't spin when you twist around the bowl or glass? | Since water is a liquid, the cup spins but doesn't really have any way to "grab" the water and spin it with itself. It will grab the water only very, very close to the edge of the cup. If you spin it long enough, more and more of the water grabs itself and eventually all the water will be spinning along with the cup.Re... |
How a comment with 2000 likes can be above a comment with 5000 likes. | There is an algorithm! The first 10 upvotes have equal weight as the next 100 upvotes .

More information: [Upvotes]', "Reddit's default sorting algorithm,... |
Planck's quantum hypothesis and the theory of blackbody radiation | We have an oven. Not the kind of oven things like pizza come out of; more like a block of metal with a cavity hollowed out of the middle and a spy hole drilled in the side so we can peer into the cavity. We heat up the block and measure the light that comes out of the spy hole. Now, imagine we capture the light coming ... |
What are the dangers of using razor blades for too long of a time? | Dull blades will pull your hairs instead of cutting them. Some razors come with a lubricant on it that can wear away adding to irritation.Cutting yourself. Which happens because each shave wears down the blade.

Why is my breath terrible after 8 hours of sleeping, but totally fine after 8 hours of being awake? | When you're asleep, you're producing a lot less saliva.

Why are parts of the world (like the northern parts of Africa and the Arabian Peninsula) all desert when they are completely surrounded by water? | There are plenty of ways a desert can form, but those in particular are formed simply because of their distance from the equator. Due to the rotation of the Earth, global winds circulate in a way that brings warm and moist air to equator. The air then rises higher, cools, and loses moisture. Next, it moves north, and a... |
the difference between white noise and pink noise. How does each work to make sound and what sets them apart from another? | In white noise, each octave has the same amplitude. But higher pitches are more energetic for a given amplitude, so there's more energy in the higher pitches. Pink noise makes the lower octaves have a higher amplitude, so they all have the same power. |
Why arent satellite phones more mainstream? Can't the big guys like Verizon at & t etc send a satellite into orbit? | Except for the coverage area, satellite phones are inferior to cell phones. Reception can be quite spotty, so the sound quality is bad and calls drop out when a satellite is no longer in unobstructed view. The phone is by necessity large and power-consuming. It's more of a winning proposition for the major carriers to ... |
Why do some people feel the need to sing along with a song they hear on the radio, or their ipod ect.. | Because people like to sing. Do you not like to sing?', "To be fair, the singing sounds better to the person singing than to the people listening.

Why are bigger sizes of the same item of clothing the same price? | The materials cost is an insignificantly small portion of the cost to design, manufacture, transport, distribute, advertise, store and ultimately sell you the product.Because the difference in the cost of fabric to make a large as opposed to a small isn't that much in many cases, but sometimes you will see a higher pri... |
How does MRI works? | Boiled down to its most basic form, MRI scans work by measuring and mapping how water is distributed through your body.

Is there any difference between sleeping for 8 hours at 9 pm and sleeping for 8 hours at 3 am? | It depends a lot on your circadian rhythm. If you consistently sleep from 3-11am it would be less disruptive and feel more restful that jumping around all over the place.

Why do dreams evoke such strong, long lasting emotions after we have woken up? | While you may know it was a dream after the fact, while you were sleeping your brain likely perceived it to be very real, and secreted the various chemicals and hormones associated with whatever you felt in the dream.

Why does Harry Potter not want to be in Slitherin? And why is there an evil fraternity allowed? | I believe he sees people from Slitherin being jerks, including possibly being jerks to *him*, personally. So he obviously doesn't want to be placed there. The fact that *this* generation of Slitherin happens to have a bunch of jerks in it that, yes, turn out to be evil, doesn't make it an evil fraternity. Now, as to wh... |
On a site like Pornhub, what happens if you watch a video that contains underaged content without your knowledge? | No - you the viewer are not liable for someone lying to someone else and them lying to you. Now if you click a video that says "17 year old slut takes one in the ass" you would be liable because you are knowingly consuming child pornography. But if someone claiming to be 18 is featured in a video and is only 17 that is... |

How come our body can absorb protein from food like cooked chicken, shouldn't they denature? | We're using the amino acids that make up the proteins to produce new proteins. Digestion denatures them if cooking didn't. And cooking chicken does denature some proteins.

How we can video games from a very short time ago be terrible compared to today's video games. | HD display and much better processors, programming, and graphics units. Console games are highly optimized for their platforms which allow for more sophistication in the artistic design/vfx end of things and allow complex images with smooth movement.

I'm not an American so can anyone explain why there's a stereotype about African Americans liking watermelons? What started it all? | Watermelons have a historical reputation of being a messy fruit, and a fruit for lazy people, because they are easy to grow, and it's hard to eat a watermelon while doing work. Many black slaves were allowed to grow watermelons on the side, and when many slaves became free, they continued to grow and sell watermelons, ... |
If the prefix "Uni" means one and "Sex" means gender, why are products for both genders labeled unisex? | "Uni" does not strictly mean the numerical value of "one." It can also mean all-encompassing, thus being of one status. Some examples: a uniform , a union , or something that is universal . So "unisex" connotes something closer to "comprising all sexes" rather than "one sex." edit: wordsBecause the product itself is un... |
Why is it that most people can count down from 10 without any problems, but most can't say the alphabet backwards without trouble? | We use numbers a lot more than individual letters.

Given a little practice, you'll become proficient.because there's no real pattern to the alphabet . The first ten numbers are the ... |

Why do some consider laws that require voters to have identification discriminatory? | It's due to a few reasons: 1) The type of fraud that would be addressed by IDs is rare. Figures for in-person voter fraud within a state during an election tend to be single-digit number of voters. In other words, it seems sorta dumb to make significant legal changes to stop something like 4 people total from casting b... |
Why do movie critics use the same vocabulary in their headlines? | i guess these are common words to make the addressed audience curious and at the same time sounding professional.i bet a movie with critics that say 'STUNNING!'

Why does a computer need to be cooled? | Because every electrical current causes warmth due to resistance.At quantify a little bit of what people are saying.

How do big time movie producers create HD remakes of a film only shot in the quality it was then? | I believe it's the fact that these films were shot on film, which have a pretty high resolution |
Why do we look for asteroids on land but NOT in the Sea ,which is much larger?Did extinctions also happen in the sea? | It is much more expensive and much more difficult to explore the seafloor than the surface of the land. Plus, the seafloor gets covered with debris much more easily than land surface. |
Why is laughter contagious? | Because your brain is wired to react to social cues. These reactions, like joining in a laugh, are survival traits for social animals. To survive as part of a group, empathic behavior is mandatory, it sets in-group/out-group dynamics and group cohesion.There are a few theories about why we laugh. But i don't think ther... |
Why would any service (such as whatsapp) use lossy compression? | > because the user would retain image quality at a lower file size No, quite the opposite - if that were the case nobody would use lossy compression. Lossy compression usually results in a much smaller file size for similar image quality. The difference between a photograph encoded with JPEG and one encoded with PNG wi... |
Why are some presidents known by their initials? Why don't we call Obama "BHO"? | George W. Bush is not known as GWB. The GWB is a bridge in New York. Georg W. Bush is sometimes known as W. . I don't know why those three are known by their initials, but three presidents out of 44 isn't much of a trend, which means there's no particular reason for Obama to be known as BHO.In all those cases, there wa... |
- When filling up a deflated tire after a recent cold snap, I noticed that some of my tires were about 5 psi overinflated. What gives? | Imagine the air in your tire as a bunch of tiny little robots. Each robot has a little motor that’s powered by heat.When they get cold the engine slows and will, eventually, stop.Warm things up though and they start to blast off like a rocket.Robots don’t really like to go on trips, they just like zooming around and ne... |
What's going in with China's Communist Party officials being charged with corruption? | Difficult to know. I'd lean toward political enemies getting purged just because that's the nature of extremely centralized political power |
What is tensor calculus and how is it used? | A vector is like a number, but instead of just a magnitude, it has a chosen direction. A covector is a linear function of vectors to their underlying scalar field, often the real numbers. Linear means that if you lengthen a vector or add vectors together, the number you get by acting on the new vector with a covector p... |
In what moment on evolution did the humans realize about their own existance? | One sunny Friday afternoon 38156 BC. No, really, we have no idea. Oldest things with no practical purpose are some 40000 years oldWe're not entirely sure when and how we became conscious of ourselves, but it likely wasn't at a single moment. One interesting fact that comes to mind is that the development of complex hum... |
