why you can't pause a YouTube video and wait for it to buffer anymore | What was happening is that people would pause videos and then leave and never come back to watch the rest of the video.

What is the point of those robo-calls that just hang up??? | The computer making the call is much faster than the humans doing the scamming, so they just keep plowing ahead making calls. If all the scammer humans are busy when you pick up, there's nobody to connect you to, so the computer hangs up. The numbers still work out so that the instant a human is available to run their ... |

There’s really no way to... |
What happened to popular musicians writing their own music? | They still do. Also, they didn't do so as often in the past as you might think. In fact, I would say the ratio of artists who write their own songs to artists who do not is probably very similar today compared to 50 years ago. |
What's the simplest task our brains perform that super computers have trouble doing? | Actual AI stuff aside: Humans are really good at pattern recognition.

Why do we get the random feeling of bugs under our skin | I've experienced this myself. My best guess: hairs on your body move and bend and when the friction on your skin from your clothes makes the hair go in odd directions, you feel a little tickle from the hair jumping back into place. Or there are bugs eating you from the inside out. Sleep tight. |
Why is the American flag backwards when on uniforms? | It's supposed to represent the direction the flag would be streaming if the soldier were charging forward. Showing it the other way would suggest backward movement. |
Why are there no parachutes in planes as a security measure? | because it's kind of hard to have 300 people that don't know jack about putting a parachute on try to do it with the plane falling out of the air. and it's pretty lethal to jump out of an airliner going 500mph, even if you're a professional skydiver. and if the pilot was in control enough to slow the plane down to unde... |
What happens to the energy produced when an engine is revved? | It's going into heat, as any physics student could have told you. Specifically, the hot gasses are producing lots of hot exhaust blowing out into the atmosphere, and a good part of them are heating the cylinder head which will heat the coolant. Also the increased friction of higher revs will heat the coolant and oil. A... |

If humans already radiate infrared radiation, why is micro and radio waves harmful to us, if they are of lower frequency? | Microwaves and radio waves **aren't** harmful to us. Not unless they're powerful enough to cook us, which is also a danger with very strong infrared light.As mentioned below, low-energy microwaves/infrared/radio waves are harmless to humans; however, high energy waves, especially ones that have more energy than visible... |
If a non-smoker started a nicotine patch program prior to smoking, would they gain any benefit from this? | Nicotine is not the most dangerous part of smoking. It's all the other chemicals and the carbon monoxide and other stuff that I'm not remembering right now. Don't smoke. It's stupid. Unless you are already addicted to it, there's really no rational reason to have a cigarette. All it will do is create a dependency on a ... |
I have heard that in quantum mechanics, simply OBSERVING something can change the way it behaves. How is this possible? | I forgot where I read this, but this helped me conceptualize it. On the quantum level, we're talking about very very tiny particles. In order to "see" them, we need to shine light on it, which means we need to bounce a photon off of it. However at our small scale, a collision with a photon would alter the behavior of t... |
Why do people sometimes get runny noses when they eat? | It's called 'gustatory rhinorrhea' - in some cases a reaction to spicy foods which are an irritant; in other cases, like if your nose runs no matter what you're eating, its a mistaken stimulation of the nerves running to your nose that create mucous - the nerves that control saliva flow upon thinking about eating, or e... |
How do car keys work? | Are talking about electronic keys? If yes, then here's an answer. I can only speak very broadly about this but I can give you a better idea.

Why does it feel colder than it actually is when the wind is blowing? | First reason is that wind is forcing convection, that is, it's renewing the layer of air around you.

Second is that the wind mechanically helps evaporating water from your skin, which is a endothermic process . Ther... |
Why is testosterone legally prescribed for transgender but not bodybuilding/muscle gain? | Because the trans man has a recognized medical condition and the dude just trying to bulk up doesn't.

When you breath into a bag you will inhale some of the lost CO2 causing your blood to become more acidic again. Your brain likes this and slows down your respiratory rate. When running you accumulate CO2 in your ... |
Why is Linux more secure even though its open source? | > If the code is available doesn't that mean malicious people can find the vulnerabilities more easily? Yes it does.

What exactly is happening when a plane breaks the speed of sound? | It's called a Prandtl–Glauert singularity. It is a cloud of water vapor that forms due to a drop in air pressure as the aircraft passes the sound barrier. As an aircraft accelerates towards the speed of sound, the air pressure around the craft increases exponentially to infinite pressure. As the craft crosses the barri... |
Why can a guitar stay reasonably in tune for days at a time, whereas a violin may need to be re-tuned even within the same long practice session? | The shape of a violin causes the top to expand and contract regularly with the weather, which moves the bridge, which stretches against the strings and loosens them. [Source: see top reply, which is from a professional.] I would guess that a guitar's relatively heavy construction, large size, and big flat front surface... |
Why do subjects in pictures look clearer than they do in person? | Probably because 1. You are seeing very close up shots of the subjects in specific conditions to highlight a lot of detail, which is blown up to a high resolution on a big screen. 2.

When I use the Unreal Engine 4 to make a game and publish it, how exactly do I pay the devs of the Unreal Engine? | You owe Epic 5% royalties of any money you make from using Unreal Engine 4, after the first US$3000.

Users of GitHub: What is the difference between git merge and git rebase? | This is my first time trying to ELI5 this particular topic so I'll try my best. > I was taught to use git pull --rebase when doing group projects on github *hair turns white* rebase ostensibly rewrites the commit history of your project, and consolidates it all to one giant push, whereas merging simply ensures changes ... |
Why do people get dark circles/bags under their eyes when tired or sick? | It is fluid buildup under your eyes. Since the skin around our eyes is the thinnest skin in our bodies, it shows fluid retention more than other places. There are three main reasons why this might happen: 1. Salt. Osmosis means that fluids in your body travel from low-salt areas to high-salt areas. So if you're crying,... |
How does holding in our breath allow us to exert more force? | Valsalva tends to help stabilize your core by increasing intra-abdominal pressure, allowing you to apply maximal force.

If my TV is running at 60hz, how can it show YouTube videos or video files at 24fps? | your TV simply shows the same picture many times. 60Hz/24fps means your TV shows the same image 2.5 times. Now you might have noticed that the Hz on your TV and the fps on the youtube video doesn't split even. So some TV's mash up the "half" image together with the image that comes after that to make it smoother and wi... |
Why do birds all sit on power lines together? | There are also birds in trees, on rooftops, etc. Power lines provide a good perch for birds to look around for food without fear of predators on the ground. There are power lines all over so they can find them easily. |
What's up with the massive hype of Deadpool as opposed to other Marvel characters/movies? | It's an interesting character design because a) he doesn't give a fuck and will say whatever is on his mind, b) he breaks the fourth wall, literally all the time, which leads to other characters thinking he's insane, and c) the books have always been, to me, incredibly fun to read, and the fact that they are getting an... |
How do they make some new muscle/pony/sports cars sound like a carborated "gas guzzling" car, and what are the advantages/disadvantages to this modification? | In some cases they intentionally reduce the efficiency of the muffler.

I wish I were jokingThe sound has nothing to do with how the engine receives its fuel air mixture. It has to do with the exhaust. The q... |
Why is Google Chrome considered by many to be a better web browser than Firefox or Internet Explorer? | Historically speaking, Internet Explorer has always been behind the curve.

Historically, IE also lacked many features ... |
When you floor the gas in a car, why does your head get thrown back against the seat? | Your head ISN\'T getting thrown back. The car is moving into your head!

Fnet=ma is the famous equation. You'll notice that it's not Fnet = ... |
How do animals eat others without having them chew through their throats or stomachs to avoid being digested? | Most animals, if not all, kill their prey before eating it. Besides an animal would have to swallow their prey whole and alive for the prey to be able to eat it's way out, and most animals don't do this. There has been one instance though where I believe it was a giant anaconda tried swallowing a crocodile whole but th... |

"The Youth" in the UK | Youths are teenagers. Chavs are scummy, usually working class, ill educated delinquents.

What, exactly, is Petro-Yuan and how will it affect the US dollar? | It creates an automatic demand for dollars that keeps the value of the currency high.

It's pretty unlikely that China will make that move in the near future, since devaluing our ... |
Do coma patients need food or water while unconscious? | Yes. That's why coma patients always have feeding tubes.

What is it about sleep that restores our body in ways that simply laying down or relaxing for a few hours can't do? | Your brain needs to process today's events and other stimuli, REM sleep allows this unconscious process to proceed while simultaneously allowing your body to regenerate damaged tissues, fully flush toxins, digest food and allows the heart to rest by decreasing heart beats. The combination of these things allows you to ... |
Why is it that when I open a window on a nice day, there is a very specific "fresh" smell in the room, but I never smell the same smell outside? | It is all about balance. There is a lot of "fresh" smell on the outside than in the inside. When you open the window, the enormous amount of "fresh" smell from the outside will eventually overcome the "unfresh" smell of the inside. When you go outside, the reason why you don't smell the freshness anymore is 1) your bod... |
why Joe Paterno is guilty of covering up for Sandusky and why the recent punishment handed down from the NCAA was just. | Because child molesting is pretty darned serious, and Paterno and the other top brass knew that it was happening, yet decided to look the other way rather than upset their winning football formula and risk losing support from students and alumni. The sanctions are a wakeup call to Penn State and other universities that... |

What would the economic impact be, especially on inflation, if 100% of fast food workers' wages were suddenly raised to $15? | Probably not much. The question has been asked by a large number of people, and the general consensus has been that you'd expect the cost of a MacDonald's extra value meal go up around $0.75 if you raised the national minimum wage to $15/hour.

Why can't we just switch our brains to a new body when our body is dead, so we can live forever? | There are two big hurdles: making sure that the brain is still viable after transplant and that doctors can actually re-attach the brain.

how are there still mathematical formulas/problems "un-proven/solved" and why can't a computer do it? | There are some types of problems that we count on the fact that they are entirely solvable but take too long to solve even for the best current computers. An example is [factoring] large composite numbers for cryptography. There are some problems we know are not solvable at all using any method. Even any super-fast com... |
What happens to all the money that Presidential Candidates raise for their campaigns if they end up dropping out? | [Factcheck] does a good job of explaining it. > As Bob Biersack from the Federal Election Commission points out, most candidates don’t have much left over to begin with.

If the government has laws forcing people to protect themselves(seat belts, motorcycle helmets, etc) why aren't yearly mammograms and other cancer screenings mandatory? | The government built the roads and has a vested interest in not having to scrape you off.

Do animals inbreed/practice inset? If they do, do they minds deteriorate after each generation because the genes mix? Why do genes do that? | Incest alone won't cause all hell to break loose on a genetic level. It is only unhealthy when practiced by a small group for many generations. The reason is simple, lets say there is a recessive gene that causes a disease, or a bad trait. Now, lets say the Smith family has that gene. Lets say that there is one member ... |
Synesthesia: When people associate numbers with colours, do they associate the concept of that number, or its written symbol with a certain colour? | I have a mild synesthesia which associates numbers with gender. When I think of the number 7, one of the things about it is that it's male, but it's not the main, most interesting thing. It's just like when I think about my dad, maleness is part of what I think about, but rarely the most important or relevant bit. Simi... |
