Why do some programs crash/become unresponsive when minimized?	[ "Let's say your computer is a line of students (programs) in primary school waiting to be served lunch (processing resources). Skyrim, the school bully, has the notorious reputation of beating other kids up to get the Fullscreen pass which allows him to cut in front of the lunch line so he gets the highest priority...	[ "Imagine a needle in a haystack that is 10 kilometers wide, and there are only 10 people designated to finding said needle. It would take them an insanely long time. They might find a few of the needles in their allotted time frame, but likely not all of them. When a game is released to the public, it's the same wa...
How are those laser-pointer temperature guages able to take a temperature by hitting something with a laser?	[ "They use infrared sensors, since heat (or thermal energy) falls within the infrared spectrum. The sensor can interpret differences in heat just like we can determine differences in the brightness of visible light with our eyes. The laser is just there for aiming, they have nothing to do with measuring temperatures...	[ "There are a few different technologies. I assume you are thinking of the touch screen on your phone screen. That works because the screen is electrified just a little bit, not enough for you to even notice. When you touch the screen it messes up the electrical field. The computer can measure how the field changes ...
Why is the understanding of nutrition so far behind?	[ "I think it's also important to consider how much power the large food corporations have. They provide research funding to help promote their own products which creates a lot of contradictory/confusing information out there. For example, some people who helped develop the government recommended food guide in Canada...	[ "Back then people still needed jobs, now they dont and can practice harder for longer. And science helps by showing then methods on improving motions. You cam find cool videos on youtube" ]
The Royal Frankish Annals contain references to "Saracens" and "Moors". Is there a precise distinction between these two terms for the Franks?	[ "I cannot comment on the Annals, but in the Song of Roland, it's clear from the text that the author has very little real knowledge of those the author calls Muslims. He makes all sorts of descriptive mistakes that a person with even passing familiarity would not make (For example, Muslims are extremely monotheisti...

Why is it common to see the flag of the Confederate States of America in states which were never members of the Confederacy?	[ "Every state has Confederate apologists in it. It's the modern way to fly the Nazi flag without flying the Nazi flag. The Confederate flag, whatever it may have once represented, is now the flag of American White Supremacists, de facto Nazis, and other far right-wing extremists like the Bundy family, whose patron, ...	[ "Greetings everyone. In the few minutes this sub has been up, it's attracting sub-standard responses.

Why the DMV is considered hell?	[ "You have 10 to 15 people waiting on a mindless task that is complicated by short staffing and bureaucracy. Then, you get a damn number. The number is normally associated with letters. You must wait. Someone is taking a shit and someone is out to lunch (at all hours of the day). So, you wait. All you had to do was ...

Biologically, what is happening when an individual is withdrawing from heroin?	[ "Just a reminder to all that personal experiences with dependence/withdrawal are not appropriate for /r/askscience. Have a wonderfully scientific day!" ]	[ "I'm sorry that I'm no expert, but I remember reading about this the last time a similar question was asked: _URL_0_ Basically, you percieve time faster after your run because of endorphines released during the work out, which means that the music seems slower. This is apparently also why a lot of rock musicians pl...
Why is it legal in the U.S. to disseminate anti-democratic and/or fundamental rights infringing propaganda?	[ "I'll answer your question with a question; how does someone displaying a symbol or flag violate your rights? What right is being violated? Freedom of speech applies to everyone and everything, that's what's so beautiful about it. While I am in no way supportive of what these symbols may or may not represent, I h...	[ "If the prosecution is still gathering evidence, then telling others _how_ they are gathering said evidence may limit their ability to do so. For example, lets say that you are prosecuting fraud at a bank and you indict a couple of low level people in hopes they will flip on higher managers. The evidence you have o...
Why isn't Windows Based on UNIX	[ "Because Windows was built on an existing framework - MS-DOS. UNIX was built for workstations, not personal computers. So it would have been impossible to cram it onto on a lightweight machine like the original PC. It was also wholly unnecessary, as its core feature - multi-user processing - was impractical on an...	[ "Misogyny. It is considered admirable for a woman to be like a guy. Guys would be debasing themselves to become like a woman. The unspoken assumption being that men are better than women. It's changing for the better right now, but society still clings to traditional values." ]
Why do fishes go "belly-up" when they die?	[ "Basically the same reason any animal floats when it dies, bacteria grows and creates air inside the corpse causing it to rise. The intestines of fish, where the bacteria starts growing after death, are located on the lower half of the fish, causing it to float belly up." ]	[ "Modern cars and trucks have multiple points of adjustment in their suspensions: Caster, camber, toe, and myriad finer points as well. C,C, and T are the major ones and, at highway speed, caster is very important. The best analogy is a motorcycle vs a shopping cart. At higher speeds, the axis upon which the front w...
Where do deepsea anglerfish get their bioluminescent bacteria?	[ "The bioluminescent bacteria species, usually [Vibrio fischeri](_URL_0_) or Photobacterium sp., are primarily symbiotic, but can also live as free living bacteria in the ocean.

How does the meat industry worsen climate change?	[ "A cattle farm produces as much waste as a small city. Meat production is highly inefficient; they have to grow grain to feed to the cattle, and the animals produce waste and gaseous emissions. It takes 3 times as much crops to feed the animals we eat than if we just ate the plants we grow. Animal farms use a third...	[ "That's quite a big topic. The [IPCC](_URL_0_) would be a good place to start; there are reports that cover most of those questions." ]
What would happen if for some reason the earth were to suddenly and instantaneously stop spinning?	[ "Yes, you'd go flying, just like if you're not wearing a seatbelt and slam a car into a wall, but this would lessen the further away from the equator you are. Really close to the poles it wouldn't do anything to you. Not that this would matter because even if it slowly stopped spinning those near the equator would ...

He also did another video on a simmilar line of - could you survive: _URL_0_" ]
Why does getting hit in the shin hurt far more than say your forearm?	[ "The \"sharp\" edge of the shin is the part which hurts the most. This is because there is almost no muscle over the bone, just a thin layer of skin and fat which makes any hit go directly against the periostium, the tissue covering the bones, which has A LOT of nervous endings. Also, as it is a sharp area, most of...

Why are we being bombarded with so many superhero movies?	[ "Because they make god awful amounts of money. Not that I'm complaining either, I have enjoyed this run this far." ]	[ "Lawyer and former state-level prosecutor here, How: That's the way history happened. The Federal Gov't has limited power, and didn't really do much in the early years, e.g., under Pres. Washington. Each time a need for a specific task would arise, say to investigate counterfeiting, a new police force would be born...
Can someone explain the basics of anti-matter to me in laymen's terms?	[ "Antimatter is matter with opposite charge. Anti-electrons (positrons) have the same mass and spin as an electron, but an opposite charge. When particles collide with their antiparticles, they release a lot of energy." ]	[ "To a 5 year old? Only Carl Sagan can do that.... _URL_0_ _URL_1_" ]
Why is it that some people can kill, skin, and prepare an animal for dinner but can't handle the sight of a kid puking?	[ "Because a puking person can be a sign that something everyone ate all together is poison (ie gone bad) and thus the people who also felt sick and puked after seeing someone else puke were more likely to survive such an ordeal and reproduce. While the people who balked at hunting animals didn't get meat and thus we...	[ "Hi OP, this is a cultural question, so it would greatly assist anyone considering answering if you could specify which culture you're asking about. For example, the name of a cultural group / country / geographic region, plus a rough time period. Otherwise, this question is simply too broad, as it encompasses almo...
If there are no size regulations regarding goalies in the NHL, why doesn't a team just throw some really obese person out there to block the whole net?	[ "An NHL goal is 6 feet wide by 4 feet wide. I doubt there's many people actually large enough to block that entire area. And if there is someone that big, I doubt they'd be able to stand up and skate their way out to the net." ]	[ "Hospitals, like most services in the U.S., are a business. It is hospital policy to not perform such operations unless some form of payment is secured. This payment could be credit, of course, where the person then pays their credit debt; or in some cases, a payment plan can be established where that patient is in...
Why does a horse need to be put down if they break a leg?? a dog or cat doesnt	[ "It doesn't NEED to in some cases. People put horses down because they are no longer \"useful\" and rehabilitation doesn't suit their financial interests. I'm thinking specifically about race and show horses, cart mules, packing burros and forest service equines. A compassionate owner would rehab the horse. But, de...	[ "Computers run on sets of instructions telling it how to run all the parts of the computer and build an interface so you can use those parts. Say you're following a recipe for a cake.

Can Australian Tsunami Warning Beacons data be used to pinpoint 370 crash site?	[ "Highly unlikely. a/ if it could, they would already have noticed it. b/ a plane crash would create only a localised splash wave that would soon be absorbed by the water itself. c/ Tsunami meters dont work like seismometers, they work in a number of ways but need fairly significant readings before they start sendin...	[ "No computer which controls a power plant should ever be directly connected to the Internet. Stuxnet worked because of the incompetency of the operators. Nuclear accidents never happen as acts of god, they _always_ happen because people made layers upon layers of mistakes." ]
Why must the singularity of a black hole be infinitely dense ?	[ "if it had volume, you would need to explain what force was strong enough to counteract the gravitational force. No such known force exist. the strong and weak nuclear forces simply are not strong enough. The force of gravity rapidly diverges to infinity when mass is very close to other mass." ]	[ "The Schwarzchild solution describes the vacuum outside of a spherically symmetric mass distribution. So if you drew a big sphere around a large enough part of the universe and removed all of the mass outside it, that would be sphere with radius smaller than the Schwarchild radius. But since there is mass outside a...
How can Zero-g flights simulate low gravity (lunar and martian gravity)?	[ "Yes. Technically you can do anything between 0 g and 5 to 6g. The high limit is more due to the aircraft limits and the fact that you wouldn't be able to stand anyway. The issue is that this is only of limited usefulness since you can only do 20 to 30s duration of \"modified gravity\". For example during the train...	[ "You're right to be confused. It is 100% wrong as depicted in the movie, and a lot of people of wondered about why they made such a grave error considering the rest of the movie was somewhat realistic. It is likely that the reason this happens in the movie is that it makes things more dramatic. Artistic license i...
After getting off a treadmill why does it fill like you're still on it?	[ "_URL_0_ Basically, it's velocitization. On a treadmill you can be running 12+ mph, but as soon you get off you got back to 0 or 2 mph. The difference of speed makes you feel like you're still moving even though you're not moving much. You might also feel dizzy, with high heart bpm because you didn't slow down for ...	[ "Those anti theft scanners use electromagnetic fields to detect those magnetic sensors that are attached to the clothing (and removed by the clerk upon checkout). As you walk past, these electromagnetic fields will induce some alternating current in your earbuds, and that's where the buzz comes from." ]
Hypothetically, if everyone used condoms for any sexual activity and they were 100% effective, how long would it take for STDs to become extinct?	[ "Only one generation, but unfortunately the human race would go extinct as well. Assuming you were able to continue the species (cloning, artificial insemination, or insuring only people known to not carry STDs had unprotected sex) you would have to consider that many animals carry STDs as well, so anyone \"monkeyi...	[ "It's determined at fertilization - it depends on which sperm makes it to the egg. Your genetic code is made up of 26 chromosome pairs. The 26th pair is the sex pair.

if we can absorb things through the rectum (e.g. alcohol), what prevents us from getting sick from the fecal matter passing through it?	[ "We can only absorb stuff that can be absorbed through the lining of the intestines. The stuff in faeces that make you sick is generally bacteria, which comes from the conon in the first place. Waste products excreted faecally are secreted into the colon and most of them aren't reabsorbed." ]	[ "Oh I have a great poop related historical fact! The death of Uesugi Kenshin. Kenshin was a 16th century Japanese daimyo who is notable for many things in his life but his death is what applies to this thread. How he died is not entirely agreed upon by historians. The generally accepted theory is that a stomach can...
Lens flare or Venus?	[ "Definitely lens flare. 1) It's in the right place for lens flare, which is generally opposite a bright light source, across the center of the photo. 2) Way too large to be Venus.

How does the nervous system work for conjoined (siamese) twins when the twins have separate minds and can think independently from each other?	[ "For most conjoined twins, I believe that the majority of the nervous system is separate. [Craniopagus](_URL_2_) twins seem to usually not share much if any brain material, although wikipedia notes [this set](_URL_0_) who share brain material and can pass thoughts between them. The [Hensel twins](_URL_1_) apparentl...	[ "The change came with the meeting between Nixon and Mao. Reading up on that meeting might be a place to start.

How important is the conductor in an orchestra?	[ "In an orchestra, more important than you would think.

how do flashbangs work?	[ "They're really just a grenade designed to be non-lethal and incapacitate. Usually something like aluminum+potassium perchlorate will be used to provide an extremely loud explosion and bright flash." ]	[ "In reading just now excerts from \"Stalingrad: The Fateful Siege: 1942-1943 By Antony Beevor\", Its talks of how Chuikov had ordered an emphasis on night raids because the Luftwaffe could not respond and that he was convinced it struck fear into the Germans.

How common was the Irish language in the US during the peak periods of Irish immigration? How many Irish monoglot were there and were there any communities that were primarily linguistically Irish?	[ "Maybe a silly question, but I'm genuinely curious: is the Irish language you're speaking of here equivalent to Gaelic? Because I always thought of the predominant language of Ireland being English. Edit: thank you for the responses! This is enlightening. For whatever reason I had always thought the vast majority o...

How much damage would the Cretaceous–Paleogene extinction event asteroid have done had it impacted the Moon instead?	[ "The crater would be about the same size as the one on earth (180km ish) although debris would have dispersed more widely.

Why do we feel nauseous when we watch someone else vomiting?	[ "In the social environment in which humans developed if one member ate something poisonous then likely the others did as well. It would then be helpful to also vomit to avoid being sickened too." ]	[ "Imagine you are made of genetic soup. Some people have ingredients that just don't go well together and make the soup taste bad.

The developer sets up an HOA with some basic rules about how the neighborhood will work. In the contract the developer writes up to sell a house, the person buying the house must join the HOA. Also, the c...	[ "Well, for one, that's not true. You can often haggle for any number of different types of purchases. But in general, arguing over the price of a tomato just isn't worth the hassle.

Why do things like eggs or dough become more of a solid when they are heated?	[ "> On my limited science background, I am aware that when energy (heat) is added to something, it would tend to progress from a solid to a liquid to a gas from the freed molecules. This is true for physical changes. > However, when cooking eggs or baking something from dough (cookies, bread) it toughens up under ...	[ "chocolate obviously sets hard, unless you add something to it to keep it from doing so. Typically this is done by making a ganache.

How do scientists prevent the submerged water in Lake Vostok from exploding out of the bored hole like a geyser?	[ "The density of glacial ice is actually slightly lower than the density of water, so the column of water that would go up the borehole (in theory, as in practice there is no space around the drill) would not actually reach the surface.

Does any other chemical produce fire other than oxygen? If so why does this not occur on Earth?	[ "Any strong oxidizer will do. It's just that elemental oxygen is the most common. Many explosives will burn without air because they have the oxidizer built in to their chemical structure." ]	[ "The amount of heat needed to convert an element is [momentous](_URL_0_).

Why is Quantum Physics incompatible with General Relativity?	[ "General relativity more or less assumes things are real particles, as you know them, and things can be broken down infinitely. Also, gravity is a thing in general relativity. Quantum physics is about breaking things down until they can't be anymore. Quantum is the same root as quantity. We broke things down into ...

Why does sticking one leg out from the covers make you comfortable instead of one leg being cold and one still hot?	[ "Same reason as elephants have big ears. The blood looses heat while flowing through your exposed leg/elephant's large thin ears, and then carries on round the body, thus cooling the body as a whole." ]	[ "Our brains didn't evolve with cars in mind.

How are animals so easily able to determine whether other organisms are predators or not?	[ "One of the main ways animals distinguish prey animals from predators is by the eyes.
