[other] Why is there no requirements for US cabinet members? | > I believe the Surgeon General MUST be an MD I don't think that's actually true, it seems that the president could nominate anyone he wanted to that post as well.

Why are Powerball and Megamillions paid out by the state that the winner resides in? | The state is typically the body that sets up and runs the lottery. The ones you mention do cross state lines, but ultimately the state still had to allow the lottery to come there in the first place.

why a c note on a piano sounds different than a c note on a trumpet | Are you sure they're at the same frequency? Trumpets are transposed instruments so a B-flat trumpet playing a note written as C is actually playing B-flat. |
Obama's student loan forgiveness act. | Reward people who borrowed too much, and went into unprofitable careers. That idiot that paid Harvard Tuition and came out with an degree in Feminist Poetry?

Isn't Google killing other websites by displaying most of the content in search results? Why do these websites allow this? | 1. They don't have to ask for permission. It's not protected by copyright, most of the data is open. 2. Google brings them more visitors than it takes . So it's still a good deal for them to allow Google to let their site be indexed. 3. Google is a commercial company and it has their interests in saving traffic on thei... |
What do the infantry do? | Infantry is still a significant part of the fighting force, but that's usually lumped in with armored units as part of the Army, usually, so you don't see any specific advertisements except for the Army as a whole. |
Why hasn't Youtube tried to remove Adblock? | I interned at a company whose main source of revenue was serving ads on the internet, and the question of Adblock came up once in a meeting. The general consensus of that meeting was that Adblock and other ways to get around ads is not nearly ubiquitous enough to be considered a problem, and not worth the work and poss... |
How can this professional belly flopper survive belly first from extreme heights in a small kiddie pool? | If you watch right before he hits the water he brings his arms down to impact the water first. This breaks the surface layer of water reducing the impact. Also there is a layer of foam under the pool that helps absorb some of the impact. I remember an episode of stan lee's superhumans that covered this. Its probably on... |
Why does a bullet stopped by kevlar do damage, but the recoil from the other end of the gun doesn't even hurt my hand | Theoretically. The amount of force that you feel when you fire a gun is equal to the amount of force you feel when you are hit by a bullet. {I have only fired a gun, never been shot by one. But this is what they say in training} So imagine firing a gun, the force you feel on your hand is spread out over your entire pal... |
What is the biology behind being a light sleeper vs a heavy sleeper? | is there such a thing as the best of both, or neither? I'm a deep sleeper in that I can sleep; in under 5 mins of laying my head down, in the middle of a loud party, on a bus or train, with an infant sleeping on top of me, with an action movie blasting on the tv, in the middle of the day if I'm tired. I'm a light sleep... |
Why were US quarters, dimes, half dollars, and dollar coins that preceded 1965 made of 90% silver? | Totally spitballing here but maybe had something to do with them being physically worth their weight in silver? Back then they were actually worth something. Now they're physically worth nothing, just like paper bills. |
Why are the glasses used for different drinks shaped differently? | It also depends on the type. Mostly it's for the smell.

How is light created in a lightbulb | Electricity heats up small piece of metal until it starts to emit photons . Make the metal heat up in a vaccum so the metal doesn't oxidize and when it gets really hot, it glows really brightly and makes a lot of light. For a more detailed explanation of how the photon is ejected look up black body radiation; it will a... |
My city just outlawed sleeping in public areas. Is this constitutionally legal? | It's dicey. The US Justice Department says such laws are probably [unconstitutional]. > “[T]he Supreme Court has held that laws that criminalize an individual’s status, rather than specific conduct, are unconstitutional,” explains the DOJ |
Why is it that every single video on YouTube now has an ad, where as ads used to only be on certain videos/channels? | Because any user can monetize their videos now, rightly so. When you monetize your videos, ads will appear. The user can configure which types of ads will appear as well. For example, you can make it so only those ads which pop up from the bottom of the video appears, or you can keep skip-able video ads on. The more ty... |
Why are we not actively domesticating any new species? | True domestication takes a very long time and changes the animals way of thinking and if memory serves me genetically as well. Most pets aren't actually domesticated like dogs are, they're just nice to us humans. I think i heard that the current level of domestication we have with dogs took nearly 50,000 years so Yup �... |
How do you find the density of an object without the Mass? | Weight is mass times gravity. So you can weigh it to determine the force that gravity exerts on the object, divide by gravitational acceleration , to arrive at mass. Then measure the volume, and compute density as you've described. |
I have every symptom for ovarian cancer, but other ailments have the exact same list of symptoms. How does a doctor differentiate between ailments that share identical symptoms? | First of all, the symptoms of ovarian cancer equally well describe far more common ailments. So that's what they'll look for, first. They'll also take a family history to see if it runs in your family, and your own history to see about risk factors. Then they might do a transvaginal ultrasound to see if there are any s... |
Why do words translated to english from another language, such as Chinese, sometimes sound nothing like they're spelled? | Because the words you mean generally aren't *translated* to English; they're imported. You're referring to [loan words], which are imported foreign words . If words are really *translated* to English, that's called a [calque] or loan translation, and the pronunciation of those loan translations is generally familiar.My... |
Does my butt have Capsaicin receptors, or is there some other mysterious reason my day after Thai food is so miserable? | Peppers have heat in the seeds and in the ribs. The seeds are what hurts coming out, they don't digest and are just as hot *but* in the wrong place. I love heat but hate the exit pain so I take the time to scrap the seeds off the ribs. Ribs *are* digested and so don't hurt on the way out.The rule is: "If it burns going... |
If you ate 20 thai chilies (~50,000 SHU) would it be as spicy as eating 1 ghost pepper (~1,000,000 SHU)? | Other terrible answer aside; I would say they are not equal in terms of perception, but there are a number of factors in play in both directions. The biggest factor here in play is how much of the heat is getting into contact with you and at what rate. The same number of SHU spread across a lot of food might not be as ... |
Why should I vote in the current American Presidential Election if I have strong negative feelings towards all runners? | The question isn't if you have negative feelings towards them both, it's whether those feelings are equally strong. Imagine one candidate in charge, and what you think worst case and most likely case would be. Now do the same for the other. If you truly believe there's no difference, even with potential nomination of s... |
Why does getting a credit check hurt your credit? | A hard credit inquiry means you are applying for credit somewhere, and people who apply a lot for credit are higher credit risks. Soft credit inquiries, such as when you pull your own credit report, don't affect your credit score. |
What are Freemasons, what do they actually do, and why are they so proud of being Freemasons? | My Dad and Brother are both Freemasons. From what I've been able to get out of them, they do a lot of charity work and it's basically a men's club with some ceremonial stuff thrown in. They also hold fundraisers for local and UK charities. They really do look after their members as well. Back in 2013, my dad was diagno... |
Why does the United States have so many military facilities on foreign soil, while other 'superpowers' do not? | There are no other superpowers, first of all. To answer your question: America is isolated from the Europe-Asia-Africa landmass by two large oceans. Over 80% of the world's population lives in Europe, Africa, and Asia, meaning that that's where most geopolitical problems are going to occur. It is difficult to support a... |
Why are people suddenly removing Confederate memorials? | First off, these are just statues and not gravestones/grave markets. And technically, they are memorials for traitors who decided to break apart from the United State in order to keep owning slaves so fuck 'em. The real question should be is why they were built to begin with and why they've been allowed to remain for s... |
There are so many porn videos for free, how do porn stars and producers, and distributors, etc... make money, and how much? | The most amount of money in amateur porn these days appears to be in live web cam modeling.

It's like any media content though,... |
Why are humans naturally psychologically damaged by taking another human's life, or killing most things? | I took a life. A guy was actively and without a doubt attempting to kill innocent people. He had to die. The best thing that ever happened to me was when I went to see the required shrink. They told me that it was okay to not feel bad about killing someone. I felt fucked up at first because I felt zero sadness or empat... |
Why did the Titanic's watertight compartments not have a watertight top? | They didn't need to be watertight at the top, as long as the top would sit above the waterline when that compartment was flooded. Remember, water will only rise to the waterline, no higher. As long as the ship was buoyant enough to remain afloat with the weight of water in that compartment, and would not sink low enoug... |
I smoke a well known brand of light cigarette. Why do I get really sick whenever I switch brands for a night? | More expensive brands have smoother blends which will not hurt your wind pipe as much as the cheaper brands.

Why do people hate Yoko Ono? | Some people dislike her because they believe that she broke the Beatles up.Some disliked her because she was too avant garde for 70's conservative BritainSome because she was not avant garde enough and they believe her art lacks substance. I don't feel that it does personally. I think she's a far more interesting figur... |
Why are there so much violence and crimes that occur in low income neighborhoods? | Many crimes are crimes of necessity. This may not just be Aladdin robbing the merchant of an apple, but a young kid who wants to enjoy his life and sees joining a gang as the only way of accomplishing this. In higher income neighborhoods there are better schools and in turn more opportunity to have a happy life without... |
Why aren't insects afraid of me? | Surprisingly enough, insects don't have a medulla oblongota.could you define what fear is to an insect?I 'd be willing to bet that most insects don't experience what we call "fear"Oddly though roaches seem to be terrified of me and quite smart about hiding from me. |

Has Anonymous actually achieved anything? | The collective works of the loosely affiliated 'anonymous' have done quite a bit.

Why isn't alchemy possible? Isn't it just protons, neutrons, and electrons that move from one atom to another? | It is possible, it isn't practical. It's not like you mix stuff in a vial and make a chunk of gold, you need a particle accelerator eating absurd amounts of power and the gold output is microscopic.As others have said, intentionally making gold is possible but prohibitively expensive. On the other hand a nuclear reacto... |
Why do we wake up each morning? What is the process of waking up? | I am not an expert, just a student studying A-Level Psychology. The light from outside is an 'External Zeitgeber', or an external cue, which enters through your eyes into the SCN in your brain. This SCN tells you it is time to wake up, and also sends you to sleep when it is dark. |
With the earths core being extremely hot and the sun constantly warming the planet, how come the earth still has cold weather and frozen continents? | The light from the sun hits the earth more densely in some parts than others, which creates a disparity in the amount of heat that is absorbed.

How are all-you-can-eat buffets profitable? | They calculate with what a average person would eat and choose a price after that calculation. There are also person who don't eat much . |
Why do switches on fans go "off- > high- > med- > low" and not "off- > low- > med-high"? | From what I understand some fans don't have the power at the low setting to overcome the resistance caused by static friction. The high power is needed to overcome this and have the fan start spinning. Then once the fan is spinning, you can switch to slow, because it would then have enough power to overcome the resista... |
If the universe is constantly expanding, then how is it infinite? | We don't know if the universe itself is expanding, but we do know that for whatever reason, if you look at a finite section of the universe, it's expanding . Where is it expanding into? Who knows. But it is expanding as shown by the aforementioned light thing .The other answers claiming that it's only the observable un... |
Why is the NES Classic in extreme hot demand right now when it's essentially a glorified emulator? | The majority of people don't know about emulators. Also emulators are technically in a legal gray area as the makers of the games are not making money off of the downloads. In this case the games that are on their are licensed and some money is being distributed. Not to mention these are plug in play. Most emulators re... |
How is it that we can breed a lion with a tiger and not a human with another type of Ape? | First, there's a huge taboo around bestiality to even try. Second, species are defined by their inability to produce viable children, meaning that the children can't survive past birth or produce another generation. We can make ligers and tigons, but the ligers and tigons can't reproduce. edit: i overgeneralized, sorry... |
How do cell phone towers route calls? Is it the same way the internet routes to different IP addresses? | . Broadly, pdjudd and AcusTwinhammer are correct: the tower is the medium through which data is sent, and the actual routing is done elsewhere. As the name implies, a cellphone's service area is divided into 'cells'; each tower handles calls for one single cell. As a device moves around the network, it broadcasts the S... |
What is the meaning of the catchphrase: "Stupid is as stupid does."? | I'm quite glad that I am not the only person who has sincerely wondered this.From my understanding, it basically means that if you are thought of as a stupid person, then everything you do will be thought of as stupid.

Why don't new shoes come laced up properly? | I've never had that problem but I know that when they receive the new shoe on the store they often have to lace it themselves meaning that different people will lace it different ways. That and if you had to do that at work all day wouldn't you want to lace shit weird ways to screw with people lol. I would.Likely becau... |
Why does pop like Sprite and 7-UP not have caffiene but the large majority of cola like Coke and Pepsi do? | Colas are made from [Kola nuts], which grow on trees in Africa and already have caffeine in them. That is the distinctive flavor of cola. Clear sodas such as sprite or 7-Up are made with non-caffeine containing things like lemons and limes. |
No Man Sky's Release and Subsequent Blowback... what exactly happened? | NMS had a lot of hype surrounding it. Some of this hype was due to promises made by the developer for unique features and other exciting stuff that hadn't really been done before on that scale. The rest of the hype was just gamers hoping for stuff that hadn't really been shown or promised, but speculated on endlessly. ... |
How DNA from blood is changed when getting a bloodtransfusion | Any DNA that was transferred to your body would soon be replaced by your own DNA because the cells constantly die and get replaced. For a few hours/days they could get mixed up, but they don't replicate so it wouldn't matter as long as your body didn't reject it. |
Aside from any odors, does "fresh air" exist? Oxygen is oxygen, right? | As well as all the scientific reasons you can't really argue with the psychological ones. To me opening windows gives me an emotional boost, especially in the winter, since just hanging out in the cold is miserable. It feels like I will actully survive to see spring. The house seems very closed in and dark in the winte... |
If microwaves and wifi routers operate at the same frequency (2.4 GHz), why doesn't a wifi router warm up objects around it? | It's a matter of output power. A microwave may generate a 2.4GHz electromagnetic wave at about 1,000 Watts, whereas a wifi router's output power is a mere fraction of that. Edit: There are some wifi transceivers meant to support networks spanning multi-kilometer ranges those antennas, you really don't want to go hangin... |
Why are eye colors so varied but all pupils are solid black? | I believe what you're referring to is that the iris consists of two layers - the epithelium and the stroma. The epithelium lies deepest and is black in all people. In fact, when people have black spots on their iris, that is the epithelium peeking through. The stroma is what gives the eyes their color. The stroma mainl... |
What is the theological justification for God killing Job's wife and children in the Bible? | > He just made them go to Heaven, which is a better place for them anyway.' Which makes negative sense to me, because by that logic John Wayne Gacy and Westley Allan Dodd are saints. If you believe most of the theology about Judaism or Christianity, at least the more traditional kind, you'd likely respond that all huma... |
Why to these new "hoverboards" keep setting themselves on fire? | There are two guys, Adam and Bill. Adam and Bill both sell toys to make money. Adam buys only the best toys so kids everywhere can enjoy them safely. Bill, however, buys cheaper toys and pretends they are expensive so he can make even more money. People buying the toys won't see much difference in the toys other than t... |
how were languages created? | Last I knew, we don't know much about how they were created. We can give a rough estimate of *when* give/take 1,000 years but no true estimate. One can safely assume, however, that different primal tribes had different words for different things and as tribes intercommunicated these systems merged into multiple, struct... |
Why gifs seems shorter the 2nd time I watch them ? | Your brain is a filter, and it filters out things that it already knows and things it finds unimportant. The first time you hear a song your brain is really paying attention but the second, third, and other times it realizes it's already done this and it's wasting precious focus if it's dealing with the same data all o... |
Why aren't all economics professors rich? | The average annual salary of an American economics professor is $95,000. Roughly 95% of Americans *with non-zero incomes* make less than that.

What exactly is inside a water tower? | You were right. What's inside a water tower is water. Water is pumped to the top, and then gravity is utilized to provide water pressure to the surrounding area. |
Why are right-wing parties so often connected to religious belief? | I am not entirely sure to what extent I buy it, but there is this claim that an important element in right-wing thought is the idea that the world is ruled by forces that are fundamentally beyond our control. Whether it is God or the market or tradition or common sense, we can do our best to play the game as well as po... |
How easy is it really to crack a safe? | For a safe you normally place in your home, its pretty easy given time and equipment. The key here is, that burglars don't really like spending extra time in your house, making loud noise and carrying heavy equipment. Of course no one uses a stethoscope, they use power tools. Maybe the stethoscope worked in long ago, b... |
If being attractive is an important aspect of sexual attraction, why hasn't natural selection turned us all into super models? | Because even if average people can't get laid by super hot people they can still get laid by less attractive people. You take what you can get. |
Why do supercars redline at 10-12 thousand RPM, but my truck redlines at 4 thousand RPM? | From what I understand it has to do with 3 things. Strength of components - high end motors are made with stronger piston rods, etc. Balance - As you'd imagine, a slight shimmy at 4k rpm is annoying, at 10k it's catastrophic, so all rotating parts are balanced to even tighter tolerances. Longevity - I think to a degree... |
Why is it that free university education in countries like Germany doesn't lead to higher proportions of college graduates? | Here in Denmark there's a limit to the number of students accepted to any given line of study. For the same reason, the grades required go up/down with popularity. This year I think roughly 25% of all applicants didn't get in.I think because Germany has an economy that allows for trades to be as well paying as universi... |
What is a RSS feed and what's the best way to use them? | I use Google Reader to view my RSS feeds, but there are plenty of others out there. But you have it exactly right, it aggregates all of the different sites you've subscribed to so that you don't have to manually go to every single one of your favorite sites to see if anything new or interesting has come out. It also le... |
What causes my green eyes to vary in color throughout the day? | I've looked this up before. According to [Wikipedia], there isn't exactly any such thing as green eyes - or rather, a green iris. Rather, your iris is a sort of hazel color, and a trick of the light called Rayleigh scattering imparts the blue color. Combined, they make your eyes look green. When the external light chan... |
Why is manual transmission preferred so much when it comes to sports cars? | Sports cars aren't just to get you from point A to B - they're built so that you have more fun doing it. Putting the driver more totally in control is more fun - manual sports cars are great on windy roads like Mulholland Drive near me because you can feel whether or not you're shifting correctly in order to corner saf... |
What is genetic drift? (I've yet to find an explanation that I understand) | Gingers, as you know, are rare. When you think about all the humans in the world as a single population, less than 5% of the members of this population are red heads. Now let's say a bus full of gingers were on their way to a ginger pride festival, when something happened and everyone on earth died, except the people o... |
Someone please tell me... Why is Shark Week such a big deal? | It is cool to see a group of shows dedicated to a majestic predator of the sea? Shark Week goes back pretty far, I remember being excited about staying up late and watching all the shows in high school in the early 90s. Back then it wasn't like you had the internet at your disposal to where you could sit there and watc... |
Why do time zones exist?? And who came up with them?? | Time zones are around to help make people living in an area easier on them, plus to standardize what time people actually agree it is. Places like China, where there is only 1 time zone, and is the length of approximately the US, are a bit strange. For example, in western China, which is about 3,000 miles from the east... |
How do we have depth perception when viewing objects millions of lightyears away in space? | Up to a certain distance, we get depth perception from the Earth moving around the Sun. We look at a star, and then six months later when the Earth has moved to the opposite side of the solar system, we look at the star again. The star will appear to have moved slightly, because we're in a different spot. The closer th... |
Why do some countries have different birth rates between men and women? | As for China They don't just have more boy babies, more of them survive to adulthood because the parents kill or neglect the girls. Men are considered more valuable, women as property. It's sick but its true. There are environmental factors to Ukraine's gender imbalance, not just birth rate but emigration, death, etc. |
How did Haggen get Safeway and Albertsons stores and then go bankrupt ? | They pretty much over extended themselves without knowing what they were getting into. They went from a regional 18 store chain to a store with over 150 locations in several states almost overnight. The customers in the new states didn't like them so much and their customer base dropped out from under them. Add on the ... |
At what point is someone an addict | This is a default sub so you're going to get a lot of answers from 19 year-old armchair scientists. You should ask r/askscience or a similar sub. |
The reason for the long lifespan of the Greenland shark. | It has thick skin, allowing it to stay in colder waters where there isn't much competition for food, and it has a very slowed metabolism which causes the heart to beat slower, allowing for it to survive longer in its environment. Hope that helps |
Why are people outraged at animals being kept in captivity at sea world, but not in regular zoos? | There are 2 things SeaWorld does that most zoos dont. 1. Whales and dolphins need much more space than elephants or rhinos. It is easy to fence off several acres of land for an elephant. But to build a several acre pool for a killer whale to swim in is much harder. SeaWorld and many other aquariums don't have the recom... |
Despite of 21st century's digital communication, which is instant, why do bank's transaction takes forever to post on my account? | Banks and their IT departments prioritize security, stability and every form of risk management over any type of technology improvement. Bank IT folks literally fear change and create massive bureaucracies to protect against it. It's a terrible place to work, but it's a great place to not do any work. |
It hurts like hell to step on a pin. How did ancient humans walk barefoot through forests full of sharp twigs etc? | have you ever seen the fingers of a guitarist?They are hardened, right. Similarly, the skin on your feet will harden to an extent that it does not hurt/ matter when you walk on twigs or rocks in the forest. Also, pins are not found in the forest. Thorns are found in the forest and they hurt like hell, even to animals. ... |
Why can't we ground ourselves/clothes to discharge static electricity? | In addition to other answers that touching something that's grounded will ground you touching the same thing with a piece of metal like a car key or a fork will ground you while acting as a resistor so you won't feel the shock nearly as much |
How do the opsin proteins we have in our eyes convert light into an electrochemical signal? | The general class of receptors that sense light are found all over your body and are also responsible for hormone action, smell, and neurotransmission, among many other things. What's the same about them all is that they sense the presence of substance that binds to and activates them, usually a small molecule or signa... |
Why the new Microsoft operating system is called Windows 10 and not Windows 9 | Because 7 8 9. At least that's what I tell myself.Code in older systems, while checking if you are running Windows 95/98, check for "Windows 9" Not the only reason, but a big one. _URL_1_', "Because Windows Nein wouldn't sell very well in Germany.Well for one thing it got them a lot of free advertising |

What is the purpose of humans having baby teeth? | Children need to eat solid food as well. We couldn't sustain ourselves on mother's milk until age seven or so when our adult teeth start growing in.Same reason people don’t come out of the womb as adults they need to come out small and get biggerI would think they come in partially to signal to the mother that it’s tim... |
Why do UV reflective surfaces not show in broad daylight | The point you're missing is the principle of fluorescence. UV as you rightly point out, is beyond our visible spectrum, but what UV reactive ink does is fluoresce.
