In the UK, there seems to be a healthy market for Ford, but Chevrolet is considered cliche. Why? | For a long time, Chevrolet did not make cars that fit European regulations or European priorities for cars. You need to remember that roads over here are very different to most North American roads. Ford have been producing effective cars for foreign markets for a much longer time and so have a much greater degree of c... |
When you practice holding your breath to "increase your lung capacity", does your physiology actually change? | A few things can happen, after a long time your lungs can increase in volume and your diaphragm can become stronger and more controlled . However the biggest change is in lowering your heart rate and increasing your tolerance to the burning feeling from CO2 build up in the body. All of these combined allow you to hold ... |
Why Oklahoma and Kansas get so many intense tornadoes | Apparently it's because of how they are situated in relation to the Rocky Mountains and the Gulf of Mexico. The way cold air from the north meets moist warm air coming off the Gulf and the way the mountains shape that air flow makes it particularly easy for tornadoes to form in those places, so they get more of them. [... |
How do doctors know a course of antibiotics is sufficient to kill off harmful bacteria? | Experience and experimental evidence. Once a doctor knows or has a good idea of what type of bacteria is causing the infection, they can prescribe the correct antibiotic . As for "how many pills would be just barely enough," that has come through experiment - it's likely that a couple of pills are enough to kill the in... |
When hate groups like the KKK, NSM, or WBC protest/rally, why do the police protect them? | They have the right to protest and rally. The 1st Amendment protects their right to protest and rally nonviolently. They are entitled to police protection, even though you don't agree with what they believe, just like you're entitled to police protection if you rally for something that they don't believe in.Because peo... |
Why is Uganda so anti gay? | It's a complicated issue. But here are two major but not-so-obvious factors: 1) Ugandans, like much of the world that was once colonized by the west, are concerned with protecting their society from excessive cultural influence by the west . Because many western societies have moved toward protecting/supporting/embraci... |
What causes you to hear a high pitched noise when a device, which has been fully charged, is still in the charger? | Small chargers today are switch mode power supplies. They work, simply said, by first rectifying the alternating mains current to direct current, then chopping it up again to pulses at a much higher frequency, transforming it down and rectifying it again. That sounds overcomplicated, but transformers for high frequenci... |
If a rainbow is made from light refracting on raindrops, why do we only see one static rainbow instead of multiple rainbows moving fast? | A given color of the rainbow is only seen from a particular angle from any given droplet of water. As a particular droplet moves it it either will direct a different color toward the viewer or nothing at all. The result is that a particular patch of the sky will appear one color while it is in fact made up of many movi... |
Why do photos of other planets look fake? | Some of the photos are false color, and not what they really look like. An actual photo of Saturn doesn't really look fake though. |
How do motor proteins actually "walk" within a cell? | A combination of experimental techniques and inference. * A laser is used to create a very short pulse of x-ray, which temporarily freezes molecules in place * Many motor proteins moving along strands of microtubule in-vitro are frozen and imaged simultaneously * Assuming that every protein motor has the same behaviour... |
Are there any countries which aren't primarily Christian where it's a different year than 2015? What year is it to, for example, Jews? | It's 5775 in the Hebrew calendar this year : 2015 Ancient Roman: Ab urbe condita 2768 Armenian: 1464 Ancient Assyrian: 6765 Bahá'í: 171–172 Bengali: 1422 Berber: 2965 Buddhist: 2559 Burmese: 1377 Ancient Byzantine: 7523–7524 Traditional Chinese: 甲午年 4711 or 4651— to — 乙未年 4712 or 4652 Copt: 1731–1732 Discordian: 3181 E... |
Why is colour blindness more prominent than any other sensory defect? | Most colorblindness is not brain-related, it's eye-related. Some colorblindness is brain-related, usually caused by brain trauma or damage. But colorblindness is mostly because of a deficiency of the cone cells of the eye. The cones are what allow you to see colors. Most people have three types of cone cells: red cones... |
Why do you feel light headed when you quickly get out of bed? | ELI5: Gravity pulls blood from the heart so your brain won't get enough oxygen and nutrients for the brain In depth :When you lay down, blood flow to the heart is facilitated by not having to work against gravity. To preserve a normal blood pressure in this scenario, blood vessels dilate and the heart beats with less f... |
Do dogs have a sense of right or wrong? | They don't have a sense of guilt like we might sometimes think they do. Rather, they know something they did was bad because they know that will be punished . They do it for the same reason any human misbehaves - they either don't think of the consequences beforehand or they'll willing to accept them |
What causes that feeling in your chest when someone "hurts your feelings"? | > According to a 2009 study from the University of Arizona and the University of Maryland, activity in a brain region that regulates emotional reactions called the anterior cingulate cortex helps to explain how an emotional insult can trigger a biological cascade. During a particularly stressful experience, the anterio... |

Why do animal like to be pet? I'd find it weird someone patting my head everyday. | I find I usually don't pat a dog/cats head, but rather give them a nice scratch/massage. Either belly/back scratch or head massage. I don't know about you, but I love when someone massages my head and gives me a back scratch . Though I do notice some dogs like being hard patted/smacked on the butt and that I'll never u... |
what is the significance of statistical power? | It is very important. The definition of statistical power is the probability that the result of your experiment indicates that the null hypothesis is rejected given that the experiment actually does reject the null hypothesis. Lets say you are developing a new medication called DRUGX for curing cancer. In your experime... |
What is the relative benefit of a full frame camera? How are the same or less pixels on a larger sensor better than more pixels on a smaller or same size sensor? | Bigger sensors deal with noise better. Larger pixels mean the signal to noise ratio is larger, so bigger sensors have better low light performance. I'm sure there are others, but this is the biggest aspect that comes to mind The downside being you need larger lenses that project a larger image which means you need bett... |
How do phones measure the juice left in the battery (ex. 27% left) | As a battery is used, the voltage it outputs will drop. By knowing how much voltage the battery should have, what its at now, and what it will be at when we decide it's dead, we can guess how much is left. The voltage is also related to the temperature of a battery as well, so this is kind of an in accurate way of meas... |
how can the Republican Party sue the president? | Anyone can attempt to sue anyone for any reason. Whether the courts listen to the suit is an entirely different question. The suit isn't for money, it's essentially a request for the courts to rule on whether the president has acted illegally or not. Regardless of the outcome no money will be taken from tax payers. |
Why you're supposed to back into a space when you parallel park | The way most cars steer, there's an effect called "front-end swing" where the front end of the car swings wider during a turn, and the back end of the car kinda just follows along. Because of that, you can be usually get a tighter fit if you back into a parallel space. First you swing your front end out, then back up u... |
why did my acl surgery (that took roughly an hour and fifteen minutes) cost just over $13,000? Where exactly is all that money going? | A few places. 1) The surgeon. These people make a not-so-small fortune for their time. They've paid an enormous sum of money and time to get the education and experience required to be allowed to slice you open. They expect to make it all back with interest. 2) The anesthesiologist. This person is responsible for injec... |
If we know the p53 protein is tumor suppressing, why haven't we been able to use this knowledge to cure cancer? | What p53 really does is it controls the cell cycle. Everytime a cell tries to multiply, p53 checks it for damage and tries to repair it. If it can't repair the cell, it calls for other proteins that cause cell death . It received the name tumor suppressor because tumors arise in it's absence, but there is no certainty ... |
What are the reddit bots? How do people go about programming them to do weird, mostly unsuccessful tasks, and why? | A reddit bot is an automatic computer program that polls reddit for new comments and/or posts and responds accordingly. This is done using [reddit's api]: just like you can go to _URL_0_ to get a nice page which shows you the subreddit and the newest posts, the program goes to _URL_1_ and gets a concise, properly forma... |
Why is Washington not in the news as much as Colorado about the benefits of legalizing marijuana? How different are the laws? | washington took a lot longer to get their recreational program up and running.

T... |
The difference between type 1 and type 2 diabetes. | The other comments are correct. I'd just like to add that with type II, your body makes insulin but your cells cannot use it, and eventually your pancreas will no longer produce insulin. Type II diabetics are the ones who usually lose toes and/or feet due to nerve damage. They also tend to go blind because of blood ves... |
Why is Tiangong-1 falling from space? | Low-altitude space stations like this are not *quite* outside the atmosphere. So the tiny bit of atmosphere at their huge altitude drags on them, slowing them down, which eventually make them fall.To add some more on existing answers: The ISS also suffers atmospheric drag and loses altitude with time. This is counterac... |
Why does the moon appear red in the "Total Lunar Eclipse" instead of being invisible as happening in "Partial Lunar Eclipse"? | When the earth is squarely in front of the sun, from the moon's perspective, you're still seeing sunlight through the edges of the earth's atmosphere. Like a 360-degree horizon. What does the sun look like when it's just at the horizon during sunrise or sunset? It's red. You're seeing every sunrise and sunset happening... |
Why does the pink insulation in houses make you itchy? | Have you ever broken a glass and you get those tiny shards of glass under your skin? You can feel that they are there, and it is a mix of itchy and maybe some slight discomfort? Same thing for the insulation. It has tiny shards of glass in itIt contains fiberglass, plastic fibres reinforced with glass. The fibres pierc... |
Why children will sometimes intentionally aggravate their parents to the point where they lose their temper. | Three reasons in combination: young kids can become frustrated at their lack of control, they haven't developed the ability to analyze the longer-term impact of their actions, and they are still learning how to use and handle emotions rather than have those emotions use and handle them. So younger ones can get really w... |
Why can't we use all the excess skin from people with extreme weight loss to treat burn victims? | Your cells have specific proteins on their membranes that serve as markers for your immune system to differentiate self from non-self. These proteins can vary from person to person, although they serve the same function. The reason you typically graft skin from yourself is that the skin will not be rejected by your imm... |
Why do certain people feel cold at a temperature, but other people feel warm at the same temperature? | Your body is unable to detect specific temperatures; in other words, you're not able to feel some temperature and say "oh, this is 82.35 degrees F." Therefore, the sensation of temperature that your body feels is relative to what you're used to. If you live constantly in cold environments, 50 degrees will seem warm to ... |
Why do mosquitoes crop up seasonally each spring? Is it a more "fit" group each year that is more adapted for colder weather, or does natural selection not apply? | they essentially lay "eggs" in stagnant water before dying off each year. once it gets warm enough the "eggs" come out of hibernation and develop into mosquitoes |
does an egg have the same amount of calories as a newly hatched chicken? | Not necessarly, when a chick forms it feeds on the yolk while it develops and grows, there actually may be a loss of calories in the process exactly as it hatches VS fresh laid. |
how does a candle burn so long? | The fire melts the wax which is drawn up into the wick which then evaporates under the even more intense heat of the center of the flame which then ignites, producing more flame, and cooling down the wick enough to keep it from burning. Basically, evaporative cooling. The wick does not burn because the wax evaporates o... |
how shows like Drugs Inc get dealers to be on their show and not arrest them? | Some shows, like [Moonshiners] do it with a couple easy tricks like, "careful editing," and "making shit up," and "lying." But real documentaries have some special permissions in the law, and they're careful not to reveal legal names or identities. That's why you'll often see the faces blurred or have interviews sittin... |
Why can we smell rain before it happens? | rain is preceded by particular atmospheric conditions. things like increased moisture, decreasing barametric pressure, etc. the natural world responds to these changes and you can smell the end result. kingintheattic has a point, mold spores love moisture, but there are lots of other plants that do weird stuff.With a t... |
How do smart watches/accessories detect things like heartbeat, steps, glucose level, etc.? | The step trackers just work by detecting the shock of your steps, just like a pedometer. Heartbeat and glocose levels bot work by shining an IR light through your skin. This allows a sensor to basically see your blood pumping. The light can also be analysed to get a rough idea of the chemical composition of your blood,... |
Why is that when we are sick, one nostril becomes really dry while the other is really runny? | Your two nostrils shift their workload back and forth; called the nasal cycle. Most of the air you inhale travels through just one nostril, while a much smaller amount seeps in through the other. The nasal cycle then reverses course and the workload shifts to the other nostril. The length of time between nostril switch... |
How do engineers get different amounts of horsepower out of engines that have the same number of cylinders without adding turbochargers etc? | The cylinder count isn't what defines the power, the displacement has a far large effect on power than cylinder count does. There are a bunch of knobs that can be turned to dial in the performance of an engine. Cylinder aspect ratio, engine displacement, cylinder count, piston weight, and valve timing all have signific... |
What is the difference between detergents for top loading and front loading washing machines ? | HE detergent has a higher concentration due to the washer machines using less water. It does not suds as much as top loading detergent. It is OK to use HE detergent in a top loading machine, you should use less detergent when doing this. NOT ok to use top loading detergent in a front loading machine, unless you're havi... |
How do child actors/actresses play roles in films and tv shows meant for mature audiences such as "Game of Thrones?" | Depends on the rules in the country, but in the US, child labor/acting laws are pretty restrictive. They have permission from their parents, they know they're acting, and they're well guarded from any potential abuse. If the parents are OK with it, and the kids are OK with it and no other laws are being broken, then ev... |
Why do people trust journalists when they say off the record? What's stopping the journalists from printing what they talked about? | Nothing is stopping them from printing such things, except the potential damage to their reputation. A journalist that gets a reputation for always printing stuff that was said 'off the record', will find it very hard to get people to agree to do interview with them / tell them anything else off the record. And when in... |
Why is it so hard for people to actually go to bed even when they are tired? | Could be a number of things. 2 biggest culprits I am familiar with are caffeine and electronics. Caffeine as a chemical inhibits the process that lets you go to sleep. So even if you feel "tired" the caffeine will prevent your sleep. Being exposed to electronics stimulates brain activity making falling asleep harder. |
What are chemical weapons and why are they considered much worse than other forms of attack? | Chemical weapons are any weapon that attacks with a chemical, such as chlorine or sarin gas. They are bannee for numerous reasons but among them is because they are non discrimination weapons that will contaminate and spread designed to kill people. Most weapons are actually not designed to kill large groups of people ... |
How common are rhymes/puns in languages other than English? | Even more common in some. In most latin-based languages, all verbs in infinitive form end in the same suffix, for example, in portuguese they end in either -ar, -er, -ir or -or. We also have suffixes for diminutive and augmentative forms, so that makes it easier to rhyme as wellTheyre extremely common in every language... |
Why wasn't Russia invited into the western world or NATO, after the fall of the Soviet Union? | Russia was part of a number of Nato initiatives and institutions but Nato's Article 10 requires a unanimous invitation to join. Russia is a proud country, it wouldn't want to aspire to Nato membership only to have a historic foe have power over them and require some sort of humiliating condition to join. That is a very... |
Why the world cant have a single currency? | Let's take a look a the Euro. It is an economic and monetary union . But it is fundamentally flawed in the sense that it is comprised of several, vastly different economies. Greece, Spain, and other southern Euro economies will never be able to compete with northern economies like Germany. Think about it, Greece produc... |
What is Sharia Law, is it laid out in the Koran, and do all Muslims wish for it to be implemented? | On your last point, definitely not! Less than half of the Muslim majority countries have Sharia law, it is not desired by all Muslims by any stretch of the imagination.It's a system of law that uses hadiths and surah for precedent rather than English common law or the equivalent. Only a tiny percent of Muslims want it ... |
Why do you need to turn a car wheel much more than 90 degrees to make a 90 degree turn? | If you imagine two gears spinning each other, where one is bigger than the other, the smaller one will have to rotate more to cause the bigger one to complete a rotation. This same principle applies to steering wheels, where you are using a gear system to control the wheels. |
How does it take minutes for a zit to form, but days for it to go away? | Its actually been slowly forming for quite a while before you can see it. When it actually becomes a detectable pustule, the infection has been increasing long enough for it to finally get pushed up to your skin enough to break through. This whole process takes several days. |
How does your stomach know when to evacuate bad food? | After you eat a "bad food", the stomach begins the digestion process and during that process some things are absorbed through the stomach lining . If bacteria, poisons or even a food that you are allergic to are sensed, it will attempt to protect itself by releasing fluid and by increasing the mucous lining. There is a... |
Why do I have to take the full course of antibiotics. Will I die? | Because if you don't, the more resistant strains of bacteria might survive . This means you've just bred a more-resistant strain of bacteria, which is now in you and can be transmitted to others . |
Why do gas prices rise in the summer? | Because summer is fun time, and fun costs more moneythey always rise a little, since speculators know this they try to buy the oil early while it is cheap . all that demand in buying futures drives up the pricehigher demand, more people drive, vacations outdoor activities and whatnot. |
What exactly is happening when a website is "under maintenance"? | It usually means one of two things. They could be editing/reconstructing the website, and that could range from small things like color changes to big things like code overhauls. The reason why they take the site down during this period is because they don't want you to be able to see the site in its unfinished state. ... |
Why do people want to restrict HB-1 visas, when the companies will just outsource after the visas are restricted? | jobs that require collaboration aren't so easy to outsource, as it's like 3x more difficult to work with someone remotely esp if the time zones don't match up. the efficiency lost makes the h1b cost seem reasonable.Also employment is a requirement of an H-1B visa. So if a job should pay $120k, the company can offer it ... |
What is the US government's role in an arms deal like the one with Saudi Arabia? | The US government is sort of buying it from the contractors. The way it works is the following: * Government put out a contract for X * Someone wins this contract* Contractors make whatever it is they were hired to make* Us government receives X and passes sells them to the foreign government. It is more complicated th... |
How is information burned onto a disc such as a CD or DVD, and how does it play in a CD/DVD player? | Tiny scratches or holes are punched in the disc by a CD/DVD/Blu-Ray Burner. When the CD/DVD/Blu-Ray is read, a Red or Blue laser is used to detect the holes and scratches so they can be read as binary code. |
What's actually going on when someone spaces out? | I think you're referring to dissociation. That can include everything from daydreaming, to losing track of the drive home, all the way to Dissociative Identity Disorder .Microsleep. Ever jumped in a car, started driving, then got where you were supposed to go but cant really remember how you got there? You were still a... |
How did the Eagle Creek Fire in Oregon jump all the way across the wide Columbia River and start burning in Washington State? | It was most likely a spot fire. Dry conditions and large gusts of wind can cause embers to leap and travel through the air hundreds to thousands of feet. I was a wild land firefighter for two seasons, and spot fires are something we are taught to be very wary and cautious of.One way it *could* have happened is some fre... |
How does time work in outer space? | Ultimately, time will function the same way. There will be some changes depending on where you go in space, but these changes won't be immediately noticeable. |
How does focusing a lens work? | A glass lens changes the direction of light that goes through. What happens with a focusing lens is that the light rays coming from an object at a specific distance in front of the lens will focus at another specific distance behind the lens. [Like this]. Objects at a different distance will focus at a different point ... |
If water is clear, why do clothes get darker when they're wet? | A wet cloth looks darker because less light is reflected from a wet cloth. Any cloth is woven from a yarn or fibre. That fibre is in turn made of smaller micro-fibres. Light comes from the room lights, or from the Sun, and lands on the cloth. Some of the photons of light are absorbed, but some are reflected and land on... |
the difference between rotten milk, yogurt and other dairy products? | It all comes down to bacteria. Different bacteria have different effects on milk products. It's the same way you get different cheeses when the base is just milk solids and lactose. The bacteria feed on the lactose and release lactic acid and other byproducts which provide each of the different products their flavor. T... |
What is meant by this FCC condition found on the bottom of my daughter's Little People® Lil' Movers™ School Bus? | FCC Title 47, Part 15 section 5.b should clarify this for you: > Operation of an intentional, unintentional, or incidental radiator is subject to the conditions that interference must be accepted that may be caused by the operation of an authorized radio station, by another intentional or unintentional radiator, by ind... |
Why are some people more prone to getting pimples? | Having suffered for a long time, I went to my doctor and they told me the following things: 1) Oil / grease. Our skin naturally makes oil to keep it healthy. The amount you make depends on many things, but genetics are the major one. Medication can control it, but - according to my doctor - consist of estrogen, and so ... |
When a movie makes significantly more money than its budget, where does all of the extra money go? How is it distributed? | Everything really depends on the individual movie. There is something called [Hollywood Accounting] which is a way studios can pretend a very successful movie lost money. Most actors and other crew just get a flat salary for doing the movie. Producers usually have a stake in the movie so if it does well they make more.... |
In the "Miracle on the Hudson" incident, were women and children given priority in evacuation procedures? | Women and children first is a common naval procedure it is called the brikenhead drill. On a plane I would have to agree with you on a orderly line being the best way |
How come it looks like your head is smoking sometimes after a workout? | It usually happens when there is a big difference in temp between your skin and the air, and it's dry out. Youre seeing steam as the moisture evaporates into the dry air. |
How do we know that the TSA hasn't stopped any terror attacks? Isn't the point of the TSA to be a deterrent? | The point of the TSA is probably to keep the honest people honest. It is the same as locking a door. You want to prevent the easy opportunity. Someone who is going to want to steal will do so, but a smart thief wants a soft target, not a hard one. Using a deterrent will not solve the issue, but it will weed out many po... |
The Smith Mundt Act (Propaganda) | The original Smith-Mundt act allowed the US State department to create and distribute US propaganda abroad. The updated version allows that propaganda to be distributed domestically. For the purpose of this act, "propaganda" is simply government telling the people stuff directly. It's not necessarily insidious, false o... |
What is the "The Right to Work"? | "Right to work" laws allow employees to choose not to belong to a union in a job that would otherwise require them to belong and pay dues. People who are for such laws argue that employees can choose whether or not to be a part of collective bargaining and that right to work laws are good for unemployment and improved ... |
How do we know the names of ancient Egyptian rulers? | If you're asking how we have a *phonetic* translation of hieroglyphics - the way the words *sounded* - it was the result of work by Jean-François Champollion and others. The Rosetta Stone hieroglyphics include names of Pharaohs that were familiar in Coptic, plus phonetic versions of foreign words which these researcher... |
How can someone hack a computer or a website? | By logging in. "hacking" is the process of finding a weakness that allows you to or, more often, tricking somebody into helping you to log into the system. At that point, you win. Hacking doesn't work like it does in the movies. You can't type furiously for ten minutes and then get into some system. You either need a p... |
Why do some people have higher pain thresholds? Why are childrens'lower? | Pain has an obvious evolutionary purpose - when something injures our body, pain is the negative feedback we get to discourage us from doing it again. Someone who didn't feel pain would be less likely avoid dangerous activities, and less likely to survive as a result. Physically, it's hard to know whether children feel... |
How does a strong blow to the head make one unconscious? | The brain is an electrochemical device. And slightly mechanical, in that it can make new physical connections. When that is bashed, it disrupts the current state, which is coordinating your activity. Blood flow, electrical signals, electrolyte balances, neurotransmitter packets, and hormones all get displaced, and all ... |
How do bees and flies get stuck inside ceiling lights? | Ok I've always wondered the same thing and I *think* I've come to a conclusion that may hold water. I think they come in through the actual fixture it's self. IE, they were inside the wall/ceiling/whatever and just sort of migrated their way towards the light and heat coming from the bulb. Makes sense to me and also ex... |
How do banks get away with withholding people's funds? | Lets you and all your friends like to play marbles. But there's a problem. Carrying around large sacks of marbles all the time sucks since they are bulky and heavy. So you tell your friends that you'll hold on to their marbles for them so they don't have to carry them around, but under one condition: They can only take... |
How long would it actually take for fictional places such as Minas Tirith/Mines of Moria to be built? | Well, in the timescale that the actual fictional places were built over, it's not *that* impressive. What's more interesting is the fact that they survived long enough to be built up so much. Moria was founded by Durin the Deathless sometime in the Years of the Trees, shortly after the first awakening of the Dwarves. T... |
Why do perfectly symmetrical cars in video games veer left/right when they are on flat surfaces? | I could be dead wrong on this when it comes to video game makers' intentions, but IRL most cars have less than perfect steering unless you just drove a brand new one off the lot. They'll slowly but surely veer off to either the left or right even on a perfectly flat roadway. |
What is the difference between those planes that leave a trail of cloud behind them and ones that don't, and what is that trail of cloud they leave behind? | It is the temperature and water content in the air that determines if a plane leaves a trail. It is the water vapor in the exhaust or pressure changes induced by the plane that triggers the formation of the trails. _URL_0_Basic hydrocarbon combustion looks like this: a O2 + b HxCy - > c H2O + d CO2 where the coeffients... |
Currently in US History class learning about Shay's Rebellion. I have no idea what's going on, can someone explain what it was to me? | Shays' rebellion was a rebellion by farmers in Massachusetts. It was bloodless, but it really spooked the founding fathers. They realized that the Articles of Confederations created a central government that was far too weak. A few years later, they scrapped them and wrote the US Constitution |
why do the majority of cartoon characters only have 4 fingers? | Drawing hands are HARD. If you try to draw a hand and it's not perfect, it looks SO WRONG and distracting to people. Instead, they don't even try. Hell, they try hard to make the hands look fake . This way it's so wrong it doesn't annoy people. It's like when robots are made to look as realistic as possible, but they j... |
How does Windows know wether I am plugin in a new printer/keyboard/mouse/etc? | every device has a chip that says what it is. like a person says his/her name to you. so you know name of that personWhen you put in the usb cord, the computer can feel something is connected. So it asks the device what it is and the ship in the printer/keyboard/mouse responds. |
How are black-and-white films colorized? | This has been something answered often on ELI5 if you do a search, but you're saying you already read several explanations. What are you unsure of - how they match the colours? Or how they actually *colour in* the colour? |
Why do humans care for their mentally/physically disabled offspring while other animals do not? | With a quick Google Search I found that there was a group of chimps who did take care of their disabled young. I think in most scenarios the disabled can't find for themselves, so outside of social animals like chimps the disabled young are the first to be eaten by a predator or fail to hunt properly. |
Why is The Wall by Pink Floyd considered an important album in rock history? | The Wall is a big concept album by a very big band, which presented it's concept - both musically and theatrically - in a very specific and very clear way, and went on to spawn a movie. It was also one of the nails in the coffin of Pink Floyd as a band. Many don't consider it to be a "real" Pink Floyd album at all. Fra... |
What is the value of stocks in companies that are too big to be bought? | Often, if you own a large chunk of stock, you're allowed to vote on the direction of the company and select the board of directors for it. Even if you don't own enough to get a significant vote, part of the value is in the ability to sell to somebody that *does* want to buy voting shares. and nobody's too big to be bou... |
Why Does Every Contemporary Christian Rock Band Sound Like A U2 Tribute? | So Christian music is developed around the ease of singing along- the real money is in licensing songs to be sung by churches during worship, so they have to have some key traits: A range that can be sung by most people, which means mid-range male voice.

how are movies being uploaded when they're not even officially out yet? (TS/CAM?/RIP/...) | Nobody has gotten it right yet. my time to shine. I used to work in the movie industry. People at work, and the academy award voters, are given DVDs of the movie for review so they can see their own work and so they can give it awards , especially if the movie comes out close to the awards and they need to see it and r... |
Why are the two sides of table-tennis racquets/bats always red and black? | They aren't always, you can get other colours. But for official matches, the international rules say that the two sides have to be different colours so your opponent can tell which side you hit with easily and quickly, since the two sides have different textures that can affect the spin differently.Source: I am Forrest... |
Why is it okay to kill animals, but wrong to have sex with them? | Personally I'd rather die then get raped by animals. In some places if you are caught doing it the punishment is death. I think it's because its fucked up and inhumane. Killing animals is also bad and frowned upon but we do it anyway for resources. |
How do "Magic Gloves" or "Touchscreen Compatible Gloves work while my regular gloves don't? | Capacitive touchscreens work by sensing conductive input. This is why you can't use your fingernail or regular gloves. The gloves you're talking about are made with conductive material inlaid into the fabric. |
Why aren't there good viruses? | It could be argued that virii [aren't life at all]. I think the best explanation is this. A bacteria, like any other animal, can make copies of itself without necessarily having to hurt anything. A virus on the other hand needs to steal things from the person it is infecting in order to reproduce. This destroys somethi... |
why does food get freezer burn | What's up dude. Master's in chemistry/ChemE background. I'm going to be dropping some science on you but in an understandable way. Air and moisture spoil everything, and I do mean everything. When the meat/food is not completely sealed, as in air/vacuum proofed, the air sucks the moisture out of the meet via an oxidati... |
Dwarf Fortress. What is it? How do I play? | A normal video game is a car. Dwarf Fortress is a car without a body, where you have to operate the windshield wipers by hand, or would if there was a windshield, where you have to blow into a tube to turn left, and where the engine is a V8 but you only get first gear, and to get it into first gear you have to poke a s... |
Why do car commercials have disclaimers on the screen (such as "do not attempt stunt driving"), but movies are not required to even when they have obvious car product placements? | The car is advertising a product, which means that a good chunk of what is being shown is factual/doable. The disclaimer is put there to tell the viewer that this is a stunt driver on a stunt course, and that you should attempt to imitate it; basically, that you shouldn't take what you see as something that can/should ... |
The difference between Java and C++ and the pros and cons of each language. | Java is like driving an automatic car. It's a lot easier, and a lot of things are done for you. There is something magical there that manages the gear changes . Everything is generally easier to do in Java, but you're going to have trouble having your car go as fast as it possibly can since that magical gearbox isn't e... |
Factors of Supply and Demand in an economic sense. | It should be pretty intuitive * If you have something for sale and 100 people want it, then you can charge a very high price for your item. Supply is low since you are the only one selling, and Demand is high since there are a lot of buyers. The "Invisible Hand" will push the price up as everyone bids high to try to be... |
