What does IBM do these days? How do they make money?
IBM isn't close to being dead. Their revenue is still in the order of over 100 billion USD. The difference is that they've moved on from consumer goods to goods oriented towards large businesses. It became removed from public knowledge, similar to how few people talk about ARM Holdings .
How has Banksy not been unmasked yet ?
Because Banksy is probably more than one person. Probably a team of artists are acting together as a collective and expressing themselves as a single entityMore than likely Banksy is a group of people.I'm pretty sure Banksy is 1 person. He had some beef with Robbo back in the day. Supposedly Robbo slapped the shit out ...
Difference between a typed and untyped programming language [Critique wanted on this explanation]
That's pretty good, imo. I would add that the type, e.g. spread, specifies some characteristics or behavior of the product without being fully restrictive, i.e. "it can be scooped with a spoon". This allows us to do the "scoop with a spoon" behavior with _any_ of that type, so you have flexibility in reusing that behav...
How does Facebook find people that I haven't had contact with in years or minimal contact ever and suggest them as friends?
Facebook gives you the option to use your email address book to look for people you know. If someone who has your email used this option, Facebook now knows there used to be a connection between you two. This other person might not have sent you a friend request, but Facebook still knows, so it might suggest this perso...

Why do we say that √9 is 3 when it is actually ±3?
giving one solution that solves the problem, solves the problem. so unless the question is asking for all solutions, giving just one solution is sufficient.Because there aren't many situations in which that needs to be specified. In whatever context this was brought up, the fact that the 3 is positive was likely unders...
What is the difference between the XBone's DDR3 and the PS4's GDDR5 memory?
It's the speed / amount it can take at one time. If you were hungry, would you want to eat 3 peanuts, or 5? Games are hungry for data so the faster and more peanuts they can chew at once the better", 'GDDR5 moves data in much larger chunks, what you want for processing video and gaming. DDR3 moves much smaller incremen...
Why "pure communism" was never implemented other than its derivatives and the differences between the derivatives?
If you asked any of those leaders, they would say, "I am implementing true communism." Then their governments fail. And people who support communism respond by saying, "Communism is still the solution. All the failures don't count, because even though the leaders read Marx, identified as communists, and attempted to le...
with the existence of OSHA and uman Resources, what is the point of unions?
Government regulations in the US are very pro business compared to other modern nations, and the purpose of HR is to find and manage people, not to shield them from the company. Unions provide workers a way to balance the scales in an imperfect labor market, and to help create and protect regulations made by governing ...
How is it not illegal for corporations to practically write laws and lobby them through congress, at the expense of the best interests of the people?
It's legal for anyone to write a law and suggest it to their Congressman. It's illegal for anyone to pay him to introduce the bill, but most lobbyists are smart enough not to do that. You don't know it, but you like this system. Because whether you support the ACLU or the NRA, lobbying does a lot of things you like. "L...
Why is it when we jump we push up with our arms to get more height?
> why does pushing your arms out and downwards increase your jump height? You are only seeing half the motion. It starts when you are at the bottom of the jump and swing your arms upward as you push with your legs. By having them moving at a higher speed upward you are storing momentum in them which is turned into move...
what happens when deodorant passes its expiry date?
It becomes highly explosive and must be cautiously disposed of using a pair of barbecue tongs. Joking! I'm JOKING! people have no sense of humor any more, I swear. Companies are obliged by law to put expiration dates on things that don't necessarily have a need for them. It's true, some chemicals may drift a bit over t...
Why does our face get puffy when we cry?
With emotional tears, the lacrimal glands are sent into overdrive, producing a continuous flow of watery tears. The fine tissues around your eyes absorb some of the overflow of tears, causing the eyes to become temporarily puffy and swollen.
How does a computer/digital watch know how long a second is?
Computers and electronic devices have an electronic component called a "Cristal oscillator", this component uses the mechanical resonance of a vibrating crystal of piezoelectric material to create an electrical signal with a precise frequency. This frequency is commonly used to keep track of time, as in quartz wristwat...
Sarte's example of the waiter and how it relates to the notion of 'bad faith'.
I am an individual with choices. Even when an outside party limits my choices, they cannot force me to choose a particular choice out of my remaining choices. When I submit to becoming an object or a stereotype, I am allowing an outside party to make my choices for me. In the waiter's case, he is striving towards becom...
What when wrong in this ↓ video, that the arms of the girl appear weirdly thin and sometimes seem to disappear completely?
She's not standing in a real room, but in front of a green screen. The software has troubles filtering the rapidly moving arms from the background.
Has pregnancies (in humans) always taken 9 months? Is there any possibility that the development time could increase or decrease in the future?
For reference, our closest relatives have gestations of 230 and 257 days, compared to our 270. Rhesus monkeys gestate for 164 days, baboons for 187. Our gestation time has slowly lengthened as we evolved to be a larger species, and could feasibly continue to do so. Essentially, bigger animals need longer in the womb. J...
Why is committing suicide against the law?
Because it creates a legal basis for the police to stop you. If it were legal, and your best friend was suicidal, you might call the police, who wouldn't be able to do anything about it. Making it illegal gives them some basis to prevent it, to seek medical treatment or institutionalization against your will, etc", 'Th...
Why does blue light make it hard to sleep?
It is related to how our bodies determine when it is time to sleep and when it is time to be awake. There is basically no naturally occurring source of blue light aside from the sun. Our bodies adapted to start producing melatonin only when we do not sense blue light. This is a good thing, because it kept us awake duri...
Why can't we feel the effects of accelerating and traveling through space?
Humans don't feel velocity - or the rate that we're traveling. Imagine driving in a car in cruise control, you really don't feel anything unless they're starting or stopping. Therefore we only feel acceleration - the change in velocity. Which is where orbit becomes interesting. Since we are moving in a circle, there wi...
, Why can't I just make my own connection to the Internet?
"The Internet" is a name for the collections of millions of miles of cables, routers, satellite links, etc. that allow computers around the world to communicate with each other. ISPs own the physical cables , and you have to pay them if you want to access their infrastructure. A good analogy to the Internet is the US r...
What is the optimum amount of sleep to have and why do we get tired more if we have a lot of sleep?
You're not tired, you're dehydrated. You go for 8 hours without drinking a thing while you're awake and you'll. Be lethargic and sleepy. Make drinking a pint of water the first thing you do when you wake up, you'll feel better in minutes.Give this a read, it's got more info than I could relay to you from memory. _URL_0...
For microwaves, why does more food equal more cook time?
You are only adding so much energy . That energy goes into the food, but the more the water molecules in the food weigh, the more energy it takes to raise their temperature the desired number of degrees.
Why do people shrink as they age?
There's also some spinal compression as you age. The discs between your vertebrae compress from gravity over time.
Why does a toaster make bread crunchier, but a microwave may make the same bread soggy?
It's because of moisture within the air. If you put bread in the microwave it has a lot of free space within it. The free space consists of a lot of oxygen thus when it is heated it makes the bread wet.The toaster in the other hand ensures the heat is exactly in contact with the bread with minimal space between the hea...
why is the Vatican City it's own country?
The Vatican used to be a far more powerful entity, controlling nearly half of what we now call Italy through the [Papal States]. When the modern nation state of Italy was formed the Vatican was stripped of all land. Eventually the Vatican agreed to give up the claim to the Papal States in return for it's formal recogni...
How cryptomining isn't just a massively wasteful system that just replaces wasting physical resources with wasting energy and computing power to create currency?
Mining isn't simply a way to hand out currency as a reward for wasting energy. The computing power expended by miners is what makes the blockchain secure, and the currency created in the process is a reward to encourage people to contribute computing power to the system. Mining is "signing" each block of transactions. ...
flat earth myth? Fact or fiction?
It was as obvious that the earth was round back then as it is now. The Greeks had even calculated the circumference a thousand years earlier. I mean you can literally see that the earth is round with your own eyes. All sailors knew that the first thing you see of an approaching ship is the mast. I think a large part of...
Why don't companies sell certain products in adjacent markets ?
Sometimes it is because something in the product specification means it requires different/additional approvals for some markets vs. others meaning they either A) delay the launch until they pass the different tests or B) decide not to bother going through that effort and just avoid that market. Sometimes it is because...
if some infinities are larger/smaller than others... Can we use this knowledge for anything in the real world, or is it just conceptual?
This is *highly* important to many areas. The concept of different magnitudes of infinities is used in several core mathematical theorems. The most common example would be in L'Hopital's rule, which basically tells you how to find an answer for infinity divided by infinity and is used in areas ranging from quantum mech...
Why does a Newton's Cradle work the way it does?
There's the energy explanation, but I can see why you 'd find that one as unsatisfying as the momentum one. I think it helps to think of the balls as collections of atoms, and contact as the repulsion of the outer electrons if they get too close. When the first ball swings down and makes contact with the second, there'...
why haven't other creatures developed their own languages?
Well, animals kind of do have languages. Bird calls, mammalian noises, whale songs, etc. They're not complex at all like ours though, and I'm guessing that's what you're really asking. Basically, no other animal has *needed* to develop a language like ours, so they haven't. I'd imagine that our language developed as hu...
Why hydrogen peroxide is used to clean wounds.
It's no longer recommended to use it unless under very specific circumstances and in very specific ways. The way most people use it is actually harmful, but since their mothers told them it's safe those stupid doctors don't know what they're talking about.
How do tv shows get their viewer ratings from people who just record them and watch them later?
There are many questions asked on how TV ratings work - please use the search function for a more complete answer. Short version: ratings are traditionally generated by a sample, not from the complete population. Nowadays, though, DVRs can *easily* report what you've recorded and if/when you watched anything. Not sayin...
Who profits from "campus custom textbooks" ?
Most likely the school and the professor get a cut from the publisher to make extra money. if you're having a generic physics class with the same lab as the hundreds of other universities/schools, it makes that material produced in mass and easier to copy and download. but if i custom make a lab specific to your school...
How rockets like the Saturn 5, the Soyuz, and the Space X rocket stay pointed up and straight. ELI5.
Before they launch, they're held in place with scaffolding. After launch, the force is controlled and directed such that up is the direction they mostly go in, with very minor adjustments in the nozzles to change direction.
How can the US go on with so much debt?
The amount isn't relevant. Its the % of debt to GDP that matters. [Sort by public debt as a percentage of GDP] and the U.S. is doing much better than other developed countries.
Why does it hurt my feet and knees to walk in shoes with really soft insoles?
It probably has more to do with the type of shoe and lack of support than the softness of the insole. If there is no arch support or something it would affect your ligaments by changing your stance.
Why are people in opposition to the Dakota Access Pipeline and Keystone Pipeline being built?
I don't have my facts 100% straight, but originally the pipeline was supposed to go through a mainly-white city that got veto-ed due to possible contamination of the water supply, but because it's going through tribal grounds, the government is totally for it. It's just harmful for the environment. Definitely not a pro...
Why do we close our eyes when we sleep? Also, why can't we fall half asleep by closing one eye for extended periods like dolphins do?
A few things: 1. we can sleep with one eye open, technically just like we can sleep with both open. 2. We don't have the capacity to put a single hemisphere of our brain into "sleep mode". This is the wonderful capability of the dolphin and it's not so much their eye it's their _brain_. Our brains can't do this - we're...
Why do media organizations ask for user permission before sharing submitted content from twitter but not reddit?
If you submit a link to Reddit, it's from an external source/site. Just because you shared it doesn't mean it's yours so there is no reason to ask permission from anyone on Reddit. You'd ask the owner of the original source of the link. Text posts and comments are easier to use under fair use - especially since you can...
Why does unhealthy foods taste better then healthy foods? Shouldn't our body make healthier foods taste better?
We evolved to crave foods that were nutrient rich- sweet things so we could get our sugar, fatty things to get fat, salty things to get salt. We need this stuff to survive, and for our ancestors millions of years ago, finding this kind of food wasn't always easy. Enjoying the taste was evolutionarily advantageous becau...
How can the governor of California sign a deal with China?
Because the "deals" he signed are meaningless. They're just a much fancier version of calling a press conference and saying "California and China will work towards reducing emissions!" The original Paris deal was the same thing: a non-binding gesture of supportLook into the Tenth Amendment for some insight. Lot of nuan...
Why do octopuses/octopi actually NEED three hearts?
As has been pointed out already, they don't necessarily *need* three hearts. They just evolved with three hearts, and because this didn't make it harder for them to reproduce, they didn't evolve them away again. On a linguistic note, "octopuses" is a perfectly acceptable form for the plural, and don't let anyone tell y...
How come a meal in Hong Kong costs a third of that in Finland even though the country has virtually no agriculture?
Price is determined by a lot of factors. Here are some: - The price of shipping . - Tariffs. If you don't know what this means, let's assume that the Swedish government wants people to buy Swedish-made vacuum cleaners only. Let's also say that people don't buy the Swedish-made vacuum cleaners because you can get Finnis...
Why is drinking too much Coca Cola/Pepsi linked with hyperactivity in children? And if this is true, how does it actually affect kids?
Other posters are correct -- Sugar has not be linked to hyperactivity, but since you asked about Pepsi and Coke, I feel I have to mention the stimulating affects of Caffine. Pepsi and Coke both contain caffine: 38mg and 34mg respectively. This is not much for an adult who consumes caffine regularly and has no sensitivi...
In the age of digital books and online publications, why are dashes still used when a word is too long to fit into one line?
You can't make your line of text indefinite--well, you can, but it makes for very uncomfortable reading. Compare reading a sentence the length of your entire screen versus one broken up over several lines When you have multiple lines, you must choose how to align them. If you left-align, there might be some space left ...
Why do people react to someone else vomiting by vomiting themselves?
My bio teacher in high school explained that it goes back to the days when an entire tribe would hunt and eat the same thing. So if one person vomited, then you would want to vomit too because you ate the same thing. Even though we all eat on our own now, the impulse remains to vomit when you see someone else do it. I ...
what's going on when you "crack" your neck or another bones?
I know that popping your knuckles causes the buildup of nitrogen bubbles to expand and "pop" it takes about 15 minutes to build back up. Thats why you can't crack your knuckles constantly. If you can crack your joints constantly, it's probably a lack of cartilage in your joints.
Why does being high make food taste better?
Inside the brain are special receptors called cannabinoid receptors. A natural chemical inside the brain called anandamide binds to these receptors. Anandamide regulates several things most notably mood, apatite, and the perception of pain . To make a long story short THC in the Cannabis binds to these cannabinoid rece...
why Cargo shorts are hated
Like Crocs , they are very practical but particularly unattractive. So people who wear them send a message "I don't much care how I look to others". So the other people respond with contempt -- if they actually care about this sort of thing -- unless it's obviously the practical thing you need for work. For example [th...
If our mathematics is base ten why is our time system based on 60 seconds=1 minute?
Because the Babylonians, who invented time used a base 60 system. This enabled them to do loads of fun things like invent accounting tables , basic geometry, and what you get in 8th grade algebra. They were awesomeBecause our measurement of time came from the Sumerians who used a base 6 counting system . Using 60 secon...
When a stock market crashes and everyone is desperately 'selling', who is actually willing to 'buy'?
The fact that not many people are willing to buy is what *causes* the crash. If as many people were buying as selling, the price would stay about the same. The fact people are desperate to sell means there are more sellers than buyers, so the price drops. The few people who are buying are either ignorant of the crisis,...
How do deep-sea creatures who live on the ocean floor survive the pressure of the ocean while submarines need airtight seals?
They aren't normal creatures. They live in the pressure, and that pressure is what actually holds them together. It makes learning about them incredibly difficult as pulling from from the ocean floor results in them basically exploding.
Why are swimmers completely ravenous after a swim meet while runners just nibbling on health food after a race?
Swimmer here, cross country as well in the fall during high school. Running uses about half of your body, your torso and arms really aren't doing anything. Being light is a serious advantage as your legs are carrying you. Its hard to hit your body's limit by running at a set pace. Swimming requires the use and control ...
Why are political ads allowed to say things that are outright untrue?
It's going to sound cliched, but the answer is Freedom of Speech. That gives people the right to say almost anything. Political speech has historically been given even more leeway than other forms of speech because there's the biggest risk of abuse if the government or courts were going to try and regulate it. The last...
How do tattoos work on actors in a movie or tv show?
On a bigger budgets film, tattoos tend to be encapsulated silicone prosthetics, that are painted using stencils, then applied to the actors skin by an appliance artist. This is done because tattoos aren't just a flat picture on skin. There's scaring and texture changes on the skin where the ink has gone in, and skin ev...
What about human behavior makes it so difficult to recreate it accurately in CGI without uncanny valley effect?
The motion of the human body has many complications including: - Muscle tremor- Vibration of muscle tissue, and differing vibration of fat tissue- Spring-like stretching of the skin- Constantly adjusting inputs to the muscles from the motor neurons', "It's not so much that human behaviour is harder to mimic than the be...
Why do cattle get nutrients from grass, but humans do not?
Cattle contain microorganisms in their rumen that are able to break down cellulose and turn in into glucose and eventually into fatty acids, methane, and carbon dioxide through fermentation. Humans lack the microorganisms to digest cellulose, but we have the enzymes to break down starch. Starch contains alpha-1,4glycos...

I do not have an answer for you, but I would like to know why as well becauseI find myself in a predicament for the past 6 months, at least 3 times per week I MINDRAPED byMilkshake" ] and since knowing is half the battle, I figure that as soon as I know why this mindrape can happen I will be ^this Much closer to a solu...
Magnetic and Electric Fields; Electromagnetism.
1. An electric field is essentially the radiating electrical energy coming from an electrically charged body. A magnetic field is when the electric field changes over time. The change can occur in field strength, or when charged particles move. This means that electric and magnetic fields are not exactly separate, they...
Why sometimes when we are too smart/too skilled we dont see simple solutions
In many cases people encounter what is called analysis paralysis. This occurs when an individual becomes so lost in the process of examining and evaluating various points of data that he or she is unable to make a decision with it. Basically over thinking, or thinking that the simple obvious answer was too easy.I'd wag...
What exactly happened to Gandalf after the snafu at Moria?
He slays the beast. He dies. While dead, he does things in the afterlife which he never talks about. He is reborn as the white, for I imagine his bravery, valor, and just doing the right thing. He then gets taken away by the eagle, taken somewhere where he gives advice, and such, I believe it was to the cliff of the bi...
Why is it socially expected of adults to describe sexual organs with euphemisms when around children?
It goes back to the old idea of morality that really became popular in the United States, and the fact that many people grew up with religious parents who didn't like to discuss sex and so when they grow up they don't like to discuss sex and so on . Its a cultural thing, in some countries it is taboo to discuss violenc...
Why aren't mental health checks a standard part of the gun purchasing process?
The main reason is that a mental health check is not quite as easy as a background check. Background checks are binary - you either have a disqualifying event in your history or you do not. They can be automated to scan relevant records, so they are easy and cheap. Mental health diagnosis requires an experienced profes...
Marginal and average tax rate
Marginal tax rate goes like this: You make 10 cookies, you keep 10 cookies . You make 10 MORE cookies, I take 2 cookies . You make 30 MORE cookies, I take 12 cookies . You make 50 MORE cookies, I take 26 cookies . So as you make more cookies, more is taken in proportion. It's marginal. BUT. Let's look at totals. You ma...
How do they forge the material that has the highest melting point, since you need something of a higher melting point for a mould?
I think you are actually thinking of the process called casting, not forging. In casting, the molds that molten metal are poured into are often not metal, but ceramic, or even sand. Only metals with relatively low melting points are cast in molds made of other metals. For example, check out the Wikipedia article on san...
Why do we "feed" bad emotions?
To be honest, it's really hard to say from a scientific perspective There are a few theories, depending on how you tend to associate yourself in psychology. Some theorize that it's a catharsis effect, similar to Greek tragedy. You sit through the music for example, in all its sadness, and at the end, when the song is o...
How does your phone know where you are tapping the screen through a plastic/glass screen protector?
Phones use something called "capacitance" to detect contact. Basically, your phone has a weak electrical current running through the screen. When something conductive gets close to the screen , some of the current travels through that instead of the screen. The phone can detect this change in current and, if it matches...
Why don't they sell bread in Zip Lock bags?
Because a Zip Lock cannot be square. It must be two-walled. So, either you would crush your bread getting it out, or you would need a zip lock bag that was much bigger than you needed it to be, which is wasteful for companiesThat packaging is more expensive? The bread I buy has a little clip that you can use to seal ai...
Why does netflix still ship DVDs? Wouldn't it be much cheaper to just stream everything?
Not everyone has broadband or wants to watch movies on their computer. Plenty of people still have TVs that aren't connected to the internet. Netflix can't get contracts to stream new movies but they can always *buy a copy*. The law says they can lend out any copy they buy, regardless of what the movie studios say.
What would a cataclysmic meteor look like to us on the ground?
If it's going to hit you directly, or somewhere near you, it will look like nothing. You'll experience nothing. The meteor will move into the atmosphere at around a minimum speed of 25,000 mph. You wont even see a flash of light. You wont even smell the ozone being produced as the atmosphere is burned off. You'll see n...
Why is there no universal Android image to install on devices?
I think the main problem is that the phone's use different hardware with proprietary drivers that aren't available to the general public.
Why is it that the majority of people require their wisdom teeth removed due to not enough room in the mouth? Or at all?
Mouths are not getting smaller. Dental hygiene is getting better. Previously, it was common to have lost at least a few of your teeth by adulthood, so the wisdom teeth would replace themWe used to eat a lot more meat and tough things so having those extra molars helped out with all the chewing.They're called wisdom tee...
How can one remember the lyrics of a song they last heard ten or twenty years back, but can't remember trivial stuff (like someone's name) that's much more recent?
Repetition reinforces neural pathways. So, as I understand it, singing along to your fav song over and over 20 years ago, build strong connections. The recent name you've probably only been told a few times, so the connection is weak.There are a lot of factors at play here but here we go 1) short term memory for new me...
Difference between a manual car w/ clutch VS manual w/o clutch (not auto).
They have clutches, just not controlled by a pedal. [Manumatic] gearboxes allow manual selection of gears, but automate the action of the clutch and engaging of gears. Also, F1 racing cars have a manually controlled 2-stage clutch for standing starts . Manumatic gearboxes will be a lot more expensive than the regular s...
How can makeup not be tested on animals?
Makeup is tested on animals .and interestingly enough some of the makeup that is tested on animals is produced using human plasma donations. If you see plasma donation centers that pay for you to donate, that product will never be used for human consumption! it goes to testing facilities and makeup producers! That is w...
Why is air from AC or Refrigerators less "breathable"
I think your question is: Why does it feel like cold air is harder to breathe? If so, 1. Cold air causes your bronchial airways to the lungs to describes in caliber = less diameter for air to come in. 2. Physiologically you have to warm and humidify the air that you breathe in before it hits the lungs. When you have co...
Why do all of my South Asian friends want to become some sort of doctor?
Asian cultures value hard work and productivity, both on a personal level and as it relates to the rest of society. Being a doctor delivers on both of those.
why do dogs tilt their head when you talk to them?
This article is speaking of humans, but I imagine the same applies for dogs. Seems to make sense for the head-titling interactions I had with my dog. "Tilting the head sideways can be a sign of interest, which may be in what is said or happening .. Tilting can similarly indicate curiosity, uncertainty or query, particu...
Why women cover themselves in movies after a raunchy scene is supposed to have happened ?
It's a convention to appease the movie ratings junta. Since ratings directly affect profits and "minutes of bare breasts" is a factor in ratings the behavior acts to maximize movie profits. Movies don't look like real life, at all, in this and many other waysThe latter option. Showing nudity can cause the movie/show to...
Why are ancient ruins nearly always found buried underground? Is the world getting bigger??
Ignoring the other comment here, the truth is that the world is not getting bigger. The reason that the vast majority of ancient ruins are found underground is because that's where they're safe. Things like dust storms and rain cause erosion, which simply moves material from one place to another. In some cases, this er...
Traffic lights that are very short.
Not every traffic signal has sensors. They would have to cycle periodically. Even with a sensor, they can fail to sense a small motorcycle , or bicycle and may be programmed to cycle periodically. In the other ELI5, they complained about hitting every red light. That is sometimes done intentionally to moderate speed. I...
Body parts are usually around the same size among mutual people, but why does penis size vary drastically? What determines that a person will have a two-inch or five-inch or seven-inch, etc, penis
Are you not talking extremes here? I did alot of sports so in the shower I inevitable saw alot of teammates their penis's. And there weren't to many extreme difference within guys with same cultural background. Just like somebody ears or nose can also be bigger or smaller. Different ethnic backgrounds is a different st...
1D, 2D, 3D, 4D & 5D
I assume you mean D for 'Dimensions' instead of the sides of a dice. A 'dimension' is just a measurement of some kind - the more 'dimensions' you have, the more methods of measurement are available. 1D is just a point. You can have two points, and they form a line - that line is in 1 dimension. Think of a ruler - it on...
What's the difference between Rock n Roll and punk?
I always thought punk was a subgenre of rock.It's called [punk rock]. Just because it's big & has many of it's own subgenres doesn't stop it from being a subgenre itself.
What causes that tiny piece of skin beside my fingernail to come loose and hang off occasionally, and why does it hurt so fucking badly?
It's called a hangnail and there are many explanations for why you get them. The most likely is that you have dry skin. Your skin is probably dry and, when stretched by the movement of your finger, it cracks or tears. Using moisturizer frequently may make this better, but hangnails are a pretty normal fact of life for ...
Why is that when it's really windy, I have to face away from the wind in order to gasp for air/breath?
You breathe by using your chest muscles to open up your ribcage. This increases the volume in your chest, causing low pressure, so the air outside your chest pushes its way in to fill the space. If you face into the wind, the air moving quickly past your face is already creating low pressure outside. If you open your c...
How much of someones sexuality relies on genetic disposition?
Nobody on the planet knows the answer to this question.This is an incredibly controversial subject, and there's also very little conclusive evidence to support the idea that sexuality is genetic at all. Also, we shouldn't assume that because something isn't a conscious choice that it's genetically-determined.
How is it that chips and bread become stale after a couple of hours of being out, yet stay fresh for days to weeks in bags filled with air?
It's not exposure to air that makes things stale. It's exposure to air *with the wrong level of humidity*. Bread is moist, and when it loses its moisture to the air, it gets hard and stale. Chips are dry, and when they absorb moisture from the air they lose their crispiness. When in the bag, these items are at equilibr...
Why windows has so many updates but looks like nothing has changed?
A lot of the updates are running in the background and don't affect the user interface. They can be things like tweaks to make certain processes run faster or be more fault tolerant, or the most important updates will close newly-found vulnerabilities in the system.
Why do some traffic/pedestrian lights have slots over the individual lights?

That's exactly what's happening. The problem isn't that we know of specific people who fight for ISIS and that they can then come back.
