Do live wires actually flail around? If so, what causes that? | Large amounts of electricity can actually cause violent motion in cables. However that probably won't happen when they're severed. I work in a high power test lab. Once you get to the 10kA to 100kA range, the electromagnetic forces become strong enough to significantly bend copper bars which are 10mm thick. That happen... |
Why do songs always sound much better in films? | I would think it's because you associate the song with cool stuff going on on screen. You associate the music with the emotions you're feeling created by the images/photography/narrative/whatever. That's my completely uneducated guess. |
Why is the G string on a guitar always the one to break? | It's not. If your G-string keeps breaking it's most likely due to an improperly cut nut and/or sharp bridge saddles. Gibson-style Tune-o-matic bridges, in particular, are notorious for breaking strings due the the sharp, knife edge saddles themselves.our rhythm guitarist used to break G strings all the time on one of h... |
Why whenever I'm sleeping in a car ride home, i wake up right before i reach my house? | From what I've noticed, there are more red lights and tight turns as you get closer to residential areas. The increased stopping, starting, twisting, and turning never fails to wake up my passengers whenever I'm the one driving home, so I assume it's similar to your situation. Especially if you've been on a road trip w... |
Why do animals sometimes just let us do what we want with them? I.E. Picking cats up. | My leopard gecko has this now. Before she ran into her hide if you even entered the room. Picking up could only later be done by carefully scooping from underneath her. Nowadays you can just lift her up like one of those arcade claw things and she doesn't even react until like 5 seconds later when she starts to wonder ... |
How does light bend? | It doesn't really. It moves in a straight line in a curved space. Unless you're talking about refraction? |
D-Day and the events leading up to it | It was necessary because Stalin had been loudly demanding a second front against the Germans for three years. Several thousand Soviets had been dying every day during that entire period, and the vast majority of the war had been fought on that front. An invasion was necessary for political reasons , for strategic milit... |
In computer colors why is it RGB, and not ROB or RPB? What significance does green have that orange and purple do not? | The exact colors aren't that important. What matters is that the resulting [gamut] covers a decent range of colors. Orange is very close to red, covering only a small triangle. Purple can already be formed using red and blue; at best you'd have a slightly deeper purple or something, covering a sliver which isn't much b... |
How does my body wake me up before a nose bleed? | A nose bleed feels very different, and it's your body's natural reaction to wake you up when it feels that something is wrong. |
Diplomats diplomatic immunity and why are they considered "above the law"? | basically they have immunity from being prosecuted by the host country, this doesn't make them above the law. In the event they commit a crime the host country will inform the home country and the home country will decide to either take the diplomat home for punishment, allow the host country to punish them, or take th... |
How do translators capture the writing style of a writer when translating books? | With great difficulty, is the answer to that question; and many a book has been ruined for some audiences by terrible translating. The gold standard of literary translation is sometimes considered to be Anthea Bell and David Hockridge's translations of the popular French *Asterix* comics -- yes, not even an actual book... |
How is it legal to post a persons image on the internet without their consent | TV is using your image or likeness in a commercial enterprise, for profit. But [taking a picture of a stranger] is legal as long as you are in a public place, and there's also no laws against posting those photos online. Now certain online activities are prohibited. Canada won't let you use pictures during cyberbullyin... |
A pea can be chopped up into a finite amount of pieces and be rearranged into a ball the size of the sun. | It's not a finite number of pieces, it's a finite number of subsets. Those subsets are composed of an uncountably infinite number of pieces of the original object. |
How can companys require MANDATORY overtime. It's not in my scope of availability. | If you can't perform the essential functions of the job, they don't need to continue employing you. It sounds like they are now including 10 hours of OT as an essential function of the job. Obviously, some jurisdictions have labor laws that would make it harder to let you go, so it depends on where you live. In most pl... |
How did mankind learn to make (what we now consider easy) stuffy like bread and beer? | Recorded history doesn't go back that far, so we just have to guess. Fire goes back to homo habilis 100s of thousands of years ago. That's a lot of time. You have to expect that people tried stuff. The whole of recorded human history is only like 5% of that much time, and look at how much has been developed. It wasn't ... |
Why would Russia bother to attempt annexing Crimea when they already have insane amounts of land? | I think this past post will help answer your question. _URL_0_ Russia's only other major naval access is in the Gulf of Finland, where in the winter ingress/egress becomes difficult with heavy ice. Siberia is too far away to easily run a naval port, they have some small ones I believe, but nothing of significance. If y... |
What causes a company's stock to crash after something bad/scandalous happens to them? Who decides that their stock prices fall? | 1) Owners of the stock fear the stock will fall because of the bad news and try to sell and get as much of their money back as possible2) Possible buyers back off because they don't want to invest their money in a bad company. Too many sellers and not enough buyers means the price gets bid down. The opposite of too man... |
What is the difference between liquid and fluid? Is there such a thing as low pressure fluid? | Anything that flows is a fluid. All gasses are fluids. All liquids are fluids. Air is a fluid, but not a liquid. A fluid which exists at relatively low pressure. Liquids maintain a constant volume. As in, they don't dissipate. If it flows and you can hold it in your hand, it's a liquid . If you can't, it's just a fluid... |
How do the automated voices on busses and trains know which station to call? | I only know about train systems, but I imagine that buses use something similar. The announcements are usually triggered based on the location of the train. Imagine you are in your dad's car. You may not know where you are, but you can use some of the available information to make a guess: * GPS: Your dad's car may hav... |
why multivitamins have over 100% DV of certain vitamins and minerals. | From The Big Bang Theory: ** Sheldon: Oh boy. Penny: What now? Sheldon: Well, there's some value to taking a multi-vitamin but the human body can only absorb so much. What you're buying here are the ingredients for very expensive urine. Penny: ** Well, maybe that's what I was going for. Sheldon: ** Well then you'll wan... |
Why do clocks often make two alternating noises (like "tick" and "tock")? | The question has already been answered but I would *strongly* recommend having a watch of the YouTube channel [Clickspring], wherein a guy makes a skeleton clock from scratch. The video production is amazing, as is his engineering skills, but the videos also help show how clocks work as he makes and demonstrates all of... |
Why has technology progressed so much in the last 250 years, compared to the first 1-1750 years. | Technology started way before that. We've got tools that are millions of years old, although not everyone may appreciate them for tools because they aren't something like a claw hammer, mind you. Keep in mind that knowledge is cumulative, also. Each thing we learn, enables us to learn new things, use new materials, sto... |
Why do microphones stop working so easily? I see this happen a lot on stage, TV etc. | Anything electronic can fail. Radio mics in particular are tricky - they're battery powered, and although a lot of sound engineers will use a fresh battery for every performance it's difficult to tell from looking at it how fresh a battery is. Headset or lapel mics have very thin, easily broken wires which can break, o... |
How are people able to trick themselves into remembering something that never happened? | It's like Sinbad said in his role as the genie in Shazam!, you first think of something kind of close to it and then your mind will fill in gaps to make sense of the world. It's the memory equivalent of an optical illusion. |
Will computers ever have a point where they can't get any faster? | Yes it will stop becoming faster and that's what's keeping current chip and computer manufacturers really busy to come up with the next technology which is called Quantum computing.We have already kinda reached that point couple years ago. That's why CPUs nowadays come with multiple cores, instead of increased speed . ... |
I've been diagnosed with tenitus (loud ringing in the ears) what's making my brain generate that noise? | I'm also suprised you didn't ask the diagnoser. The brain is interpreting something and producing the ringing. There are several ways this can happen. Damage to the ear drum, damage to the hairs in the cochlea, damage to the nerves going to the hearing processing centers of the brain, damage of the processing centers t... |
why do people breathe into a paper bag when hyperventilating? | Yes. Finally I time when I can give a great explanation. It's very simple when you hyperventilate you lose a lot of CO2 from your body. Now this is important because CO2 is used in your red blood cells with the enzyme called carbonic anhydrase to produce carbonic acid. What this does is decrease your pH level. If you w... |
Why we say "hamburger" and not "beefburger". | It's *believed* to have originated in Hamburg, Germany -- thus we have hamburgers. Note on the word 'believed': > the meat product so called from 1880 , named for the German city, though no certain connection has ever been put forth, and there may not be one unless it be that Hamburg was a major port of departure for G... |
Why can't satellites be used to search for aircraft crashes? | They can be. But they still aren't going to do much unless you have a real small area to search for. |
How can a ghost pepper "burn a hole" in someone's esophagus? | Just to add to this, how do peppers burn peoples skin at all? I've seen multiple sauce labels and videos that talk about not letting it come into contact with your skin. |
Why do Republicans dislike the Department of Education and Common Core? | Yes, it would differ widely, but a lot of people dislike THIS common core, not the concept that the same thing should be taught across all the country Here's John Oliver highlighting a lot of problems with the system currently _URL_0_", 'Control over education is seen as an integral part of local government by Republic... |
Why do animals of the same race/species look very identical but humans, same or not of the same race/species, look different? | Fur hides most differences in bone structure for one. Completely shave 2 sibling dogs and they'll look a good bit different |
Why is the new Valve/Skyrim mod situation so controversial? | Before this fracas, there was little to no expectation that a mod would get finished, work as advertised or be compatible with others. Now with paid mods, the consumer certainly has that expectation but there is no way to enforce it. So if a mod is unfinished or broken and you paid $5 for it, you feel like you got shaf... |
What caused the fall of ancient Rome? | This is a very old question with no settled answer. As Lamb_Sauce says, it is likely more than one thing. Suggestions have ranged from Christianity to lead in the wine jugs to the taxation system. One theory is that once empire stopped growing, its military gradually decayed. Rome kept troops on the border for defense.... |
Why can some people hold their bladders for ages, while others have to run to the bathroom every hour? | I think it's just bladder size. My grandfather was that annoying road trip person, but that was because he had part of his removed not to mention some people have overactive bladders in general. |
; How much diamond has not been uncovered yet? And how much will the price of diamond be when all of it is uncovered? | When it's all uncovered, we'll just make diamonds in the lab. Diamondel, Diamonique, DiamondAURA, all that shit will be the new diamonds. Or we'll just use a different stone. |
Why do we need to wear underwear? | You don't. Most people find it more comfortable. No offense, but this is a stupid question. Would you wear jeans without underwear? Underwear is meant to be comfortable while your outside layer is meant to be practical.cleanliness. comfort. in case your pants happen to stretch out and sag a bit.So I don't have to wash ... |
Why are there almost never any relatively successful crash landings over water? I thought planes were designed to naturally "want" to fly even when the engines are cut. | Sea conditions are a factor. My father flew seaplanes in WW2. The sea conditions determined whether they could land, and that was under power, in a plane designed to land on water. They lost several trying to land to pick up airman and seamen in the water, as the waves were too large. I have a photo of the tail of my d... |
Why is it so hard to figure out the optimal diet for humans? | Humans live a long time so it takes atleast a human lifetime to determine whether the person made good or bad dietary choices. But there are so many variables - other lifestyle factors, exercise, availability of foods, food intolerances, people self reporting what they do not work in practise and so on. Science is a bi... |
Does Quantum Physics disprove true randomness? | Please elaborate: in the text body you say that randomness had been proven by quantum mechanics and you want to confirm if that's true. But in the title you're asking if quantum physics *disprove* true randomness? |
Why is it that we limit the terms for President and not for Congress (In the US)? | There never used to be term limits for President. But after George Washington stepped down after two terms it sort of became tradition. Then FDR came along and decided to run for a third and then a fourth term. His political opponents got butthurt and decided we need term limits. There have been movements to pass congr... |
Why (or how) do SSRIs make people feel suicidal? | I can't help with the scientific info you want, but having been through over a decade of depression and half a dozen different meds myself, maybe me saying what it's been like for me might help? Out of all the ones I've been prescribed, I've only had one drug temporarily make me suicidal. It didn't give me newfound ene... |
Why are politicians working against Tesla? | For a non 'oil companies are the devil' answer, it is not that politicians are directly working against Tesla, it is that they are not working towards Tesla. Many states have laws that make it illegal for a car manufacturer to sell directly to customers. These laws require that cars must be sold by local dealerships th... |
Is it better for your currency to be more valuable or less valuable? | A bitcoin costs 645 USD. A Japaneses yen costs .01 USD. That doesn't tell you much of anything about whether these currencies are worth owning . It's quite arbitrary. What does matter is if they're changing. If Bitcoin is going UP, you want to buy bitcoin. If it's going DOWN or an analyst tells you it's going to go dow... |
Why does putting frozen meat in very cold water defrost it fast? | This is from a physics point of view, if you want any further explanation don't hesitate to ask! Water is a much better conductor of heat than air is. Heat and temperature are, on a micro scale, the rate at which things are moving . Water is more dense than air so there are more particles for the particles in the froze... |
What is the logic behind alimony? | The idea behind alimony is to ensure the woman continues to have a reasonable standard of living past the divorce. For example, man and woman get married, both have promising careers. Both mutually agree that the woman will dial back her career so that someone will be at home with the kids. Doesn't really matter, all m... |
what does the freezing of hiring federal civilian employees across all boards of the executive branch mean to the average young American adult? | To the average young American adult, not much. The only people effected immediately will be those who are seeking employment with the Federal government. If you fall in that category, it sucks to be you. Over the long term, we will see the problems begin to mount as organizations lose efficiency. Most young adults don'... |
Why do AMD processors cost so much less than Intel processors? | It's been said already here, but the issue boils down to hardware features not just raw power. The Intel chip you linked is an i7, which means that each core actually is able to present as two logical cores. So it's a 3.7GHz 4-core, but it'll behave very similarly to an 8-core. Additionally, intel chips are generally c... |
- Why Gandalf chose Bilbo. | In LOTR, Wizards aren't human, or even mortal. They are essentially minor angels, sent to Middle Earth by Eru Illuvatar to protect the world. As a result, Gandalf has more senses about what he should and should not do than an ordinary mortal might due to his semi divine nature. This may have played a role in his choice... |
DNA and relationships between organisms | You don't share 50% of your DNA with your siblings. It is a *MUCH* higher number than that.What you share with your siblings are phenotypic traits that might be close to 50% . Phenotypic traits are things like brown hair, propensity for acne, chances of becoming bald. Those traits require a tremendous amount of DNA to ... |
What are white dots/lumps that form underneath nails? | The calcium/zinc deficiency myths are untrue. These white marks are the result of mild to moderate trauma to your nail. Nails grow slowly. If you start to see the spot, it's possible you bumped your nail weeks before the mark showed up and most likely bumped base of the nail. It's a condition called ***Leukonychia***. |
Why can't a nuclear missile be shot down/intercepted like conventional ballistic missiles? | It can. The issue is that there are *so many* nuclear warheads. The scale is completely different. Russia and America each have thousands of warheads. These missiles move much faster than the old rpg rounds Hamas is shooting at Israel, and they can be launched from land based silos, submarines, and airplanes. The confl... |
Why do some companies *cough*Reddit*cough* make their apps country restrictive? | Legal and/or customer experience. There may be laws in certain countries that require the developer to do certain things and the developer hasn't done those things for that country. Or the app is missing a lot of what a local audience may expect and the developer would prefer to just not provide the app at all than ris... |
Why do hiccups disappear when someone shocks you? | Whenever someone I know gets the hiccups, I get all up in their face demanding that they hiccup this instant. THIS INSTANT. HICCUP NOW! NOW! I'll give you 10 dollars if you hiccup NOW. It's got like a 75% success rate. |
Why can I remember some dreams very vividly for a long time, and others I forget within a minute of waking up? | I think I remember reading somewhere that dreams are usually useless information so your brain doesn't store them to long-term memory. I'm not too sure why this is not the case for all dreams though. |
Why did I get influenza the last three times I got a flu shot? And why did I get a full on infection and pneumonia the last two of those times? | Did you get the shot or the live virus. The live virus can be more likely to give people the flu because it's live and if you tend to be more susceptible then you are more likely to be one of the ones who will get it. . As for the pneumonia, you can become more susceptible to that when you have the flu but the shot its... |
How can so many mobile games be blatant ripoffs of games belonging to larger, more successful companies without their makers being sued into oblivion? | In most cases, the ripoff just barely skirts around being totally copied from the original. As long as a work is technically different, even if it's almost completely similar, the larger company can't sue because no plagiarism has taken place. Sometimes, even if a work was taken exactly from the original, some countrie... |
--What happens when you get a parking ticket--but some jerk comes along and takes the parking ticket off your windshield? | The city/town will probably send you a reminder by mail right before it's due. Also, if the city/town has a website for their department of revenue, you can probably find out how much it is and pay it. |
How far back in time do we need to go until we find a significant biological difference from today's humans? | A small tidbit - our teeth have changed in the last few centuries. When we see skulls dug up their teeth line up much more. Top and bottom front teeth touch but don't overlap like modern humans. This is because we cut up our food to eat whereas ye olde folk would have to tear bite sized chunks more.Pretty sure I got th... |
Why does food microwaved in commercial kitchens turn out much better than what someone can do at home? | proper equipment, things are being cooked at the proper temperatures. Home equipment is often cheaper and you aren't doing it the same as the restaurant. Like a pizza oven or things cooked on a flattop grill. If you used the same equipment, or paid more attention to the temperatures you are cooking at it would turn out... |
- Why does Hollywood keep churning out terrible sequels and remakes, that no one likes or asked for? | > Terminator 2: Judgment Day: 200 million > Tron: Legacy: 170 million > Rambo: First Blood Part II: 150 million > Pitch Perfect 2: 180 million > Austin Powers: The Spy Who Shagged Me: 200 million > Bad Boys II: 140 million > The SpongeBob Movie: Sponge Out of Water: 150 million > The Matrix Reloaded: 280 million > Rush... |
What ACTUALLY happens at an eye exam and what am I SUPPOSED do say? | > I recently had an eye exam and apparently one of my eye's prescription got better? That is not as crazy as it seems. If you prescription was off, you are going to suffer from eyestrain, which can make you eyes even worse. You next prescription is written against your strained eyes, and allows them to relax, and see b... |
If the earth is going around the sun at 67,000 MPH why can't we feel it? | The same reason you don't feel like you're moving in a car going 60 MPH down the highway. Your movement is relative to the car's, just as your movement is relative to the earth's |
How is milk made biochemically? Do we understand it well enough and have the means to make it artificially (either cow or human milk)? | Often times on Dairy farms, a milk replacer similar to baby formula is given to calves when milk supplies is short. The blunt of this strategy is that this replacer is more expensive usually because it has medications to prevent against common calf diseases such as scours. Milk is made by cows. And at this point in his... |
Why are books better than other forms of media? | Books are seen as the most intellectual form of media because they've been around for thousands of years. All of the very best thinkers in human history have written down their ideas, and the way we get to hear them is in books. Sure, some great movies have been made in the past 100 years, but how could that ever compa... |
Why do I have sudden spurts where I have to get up and pee every 15 minutes and the urine is perfectly clear even though I haven't drank any water? | I don't have any idea. You should probably consult a doctor or pharmacist about any medical related questions/issues you may have or at least go to _URL_0_ |
How do TV ratings create a profit for a broadcasting company? | If you want to sell widgets, you want to advertise them to the people most likely to buy them. The classic example is diapers. You wouldn't waste your money trying to sell diapers to people who don't have babies. They're not in your target market. So the value of a TV spot, to the advertiser, is a function of how many ... |
If water conducts electricity, why does humidity *prevent* static shock? | Not quite related to the question but pure water doesn't actually conduct electricity. Water is typically conductive because of the minerals and contaminants in it, not because water itself is conductive. |
Stocks are down worldwide (apparently as bad as the 2008 financial crisis). What does this mean for your average Joe? | As someone who has worked in the markets since 2007 I can tell you that reaction wise this is nothing like 2008. That's media spin talking. Back in 2008 there was real craziness. Watching companies die, and not knowing when the DOW was going to bottom out. There were a couple scares, and several layoffs. Somehow I was ... |
Why does bread stop expanding while it bakes? | That browning - which I believe is a form of the Maillard reaction - happens without the presence of water. I believe what happens is that the steam evaporating from the bread suppresses the reaction at first, but as the water either evaporates or gets incorporated into the bread's structure you see more browning. In f... |
What would happen to the economy if everyone tried to live frugally and save money? | It's a bit of a contradiction in that from an economic standpoint, saving is best done in moderation, but from a personal standpoint, you generally want to save as much wealth as you realistically can. Too much saving can be a problem if it's too widespread. It's an issue Japan has been grappling with- both individual ... |
Mechanic shops and how they determine rates for labor/repairs? | The computer program is doing some basic calculations based on things like the average time that task takes, the cost of labor in that area, the overhead cost for the shop, equipment and parts they'll use in that task, and the car's make, model, and year. The point of having the computer calculate the price is so that ... |
Why do we have to actually swallow to enjoy food that tastes good and not just chew it for taste, then spit it out? | I think the simplest answer would be that the rewards center in your brain isn't firing because if wasn't craving food. The biggest part of your enjoyment of eating is that your brain signals hunger, and then you eat, which directly satisfies a focus --hunger-- and therefore fires your rewards systems. Just eating when... |
If WhatsApp chats are encrypted then how Facebook is going to collect data from WhatsApp chats for targeted advertising? | How it works: you randomly generate a private-public key pair. The public key can encrypt a message which can only be decrypted by the private key. When you want to chat with someone, you send them your public key, they can then use it to encrypt their message, send it to whatsapp, which then forwards you the encrypted... |
How was cursive handwriting invented? Why was it ever considered important? | When people were writting with quills and fountain pens, often when you first put the pen to paper it creates a splotch upon initial contact. When trying to write really fast, and constantly picking up and putting down your pen, it can mess up a document really fast. With cursive you don't need to pick up the pen for e... |
What does it actually mean when a soap says it "kills 99.9% of bacteria"? | I'm gonna go out on a limb here and say that it means 99.9% of the bacteria that it comes into contact with cease to live.It means that the soaps most probably DO kill 100% of the bacteria present, but we lack the detection accuracy to prove that all of the bacteria is in fact destroyed.Means they don't want to be sued... |
Why is there so much hate for Israel, especially among those left of center? | Mostly its treatments of the Palestinians and its illegal expansion into Palestinian territories. It's not just outrage at the country's policy. As you said there are a lot of countries doing bad things. But this one is heavily supported by the United States in its policy. Just imagine if an African genocide was sponso... |
How do horse racing odds work and why can some work out to 3-5, where you can only lose money? | That's not what it means. You always get your original bet back on top of your winnings. So a $5 bet would have a payout of $8. |
Why in the US cops can kill and people are allowed to own guns and kill too in self defence? | **Why, in the United States, are police allowed to use lethal force, and why are citizens allowed to own firearms and use lethal force in self-defense?** Constitutional rights, for the gun ownership. As for lethal force, it is expected that, when a firearm is drawn, it will be discharged. For police and civilians, this... |
How do "Government Leaks" actually happen? For example Amber Rudd... Does someone steal a file? Forward an email? Take a screenshot....? What happens? | 99% of the time: a member of staff in the department takes the information in whatever format it is in and sends a copy to a journalist. It sounds all clever and tech-espionage but really it's just adding attachments to emails. |
What exactly is an ethical dilemma? | An ethical dilemna is when you're faced with a choice where both answers are morally wrong, and you still have to pick one. This then requires you to weigh different morals against one another and pick a favorite. Imagine, for a moment, that you find yourself back in time having lunch with Hitler's grandmother. She's a... |
How did they get the background to move in "The Max Headroom Incident?" | _URL_0_ Green screen technology has been around longer than you think. If it wasn't that it could have been rear projection. _URL_1_ Looking at the actual footage it looks like a section of corrugated roofing that's physically rotating. A practical effect, if you will. |
Why do only people in the military widely use 24-hour (Further than 12)? | Because if read too quickly, 8:38AM could be mistaken for 8:38PM. A can look similar to P , and both of them end in 'M'. If it says 20:38 then there is no mistaking what time we are referring to. |
Why do we associate the color white with "plain" and "empty"? | /u/sabrinapemberton suggested a lot of good contributors, but I'm going to add a couple more that are associated with largely white landscapes: winter, beaches and salt flats. Snowscapes, particularly during blizzards are often desolate, cold and empty. Life is usually largely absent and the environments are frigid and... |
How would an ISP realize that you're running a server on their network? | Same way they bust you for illegal file sharing: complaints. Abuse is a good way to attract complaints. Their legal language is intentionally vague, because there are many products on the market that are functionally servers. PVR boxes, home automation systems, network cameras, weather stations, multi-player gaming, VP... |
Why is "IZombie" able to talk about copyrighted material like "Warm Bodies" and "Sons of Anarchy" | It's usually not a copyright violation to mention the names of other copyrighted works. Often the names, by themselves, are too short to be subject to copyright protection. Some uses of a title could be a trademark infringement, but that would only be if it either creates confusion or somehow reduces the value of the t... |
Why does human and livestock feces contaminate/pollute rivers when fish and native species also poop near or into the water? | There are two basic answers here. The first is that water really ISN'T all that safe to drink. It's full of bacteria and parasites if not treated in some form or fashion. Hence when you need to boil, filter, use iodine tablets, etc. if you're drinking from most natural water sources - at least if your body doesn't have... |
Why are revolver type pistols still popular during our modern time? what advantage do they have over clip based more modern designs? | The biggest advantage is they can fire long or very powerful cartridges that would require a massive grip or don't work well in [blowback or short recoil operation] most semi-automatics use. Gas operation used in rifles and the [Desert Eagle] makes for a much larger, heavier pistol than a revolver. Single action revolv... |
How come google can return "About 9,630,000 results (0.17 seconds)," but it takes my computer several minutes to search for a file on my hard drive? | The reason is that Google doesn't physically check the webpages for what you're looking for when you're looking for. Instead Google is an indexing search engine. It looks at every website it can BEFOREHAND and then determines the words that map to that website. Therefore when you type in your search query, it doesn't c... |
The point of keeping documents "classified" for X amount of years | So anybody involved is dead. Example: In Ireland it's rumoured Eamonn De Valera had been told the English would not grant Ireland complete freedom. Knowing this, he sent Michael Collins to negotiate the separation of Britain and Ireland. This would of course make it look like Collins had failed or been an incompetent n... |
Why are movies still shot ~30 fps and not 60 or more? | Wasn't there a big brouhaha about The Hobbit being filmed at 48fps, and a lot of people didn't like the way that it looked? Sorry to answer this question with a question, but it is also sort of an answer. I think after that, many directors might shy away from a higher framerate. People said it looked too realistic - no... |
Why can't CPU's size (width and height, not memory size) increase? | In a 3ghz processor, electric signals travel about 6cm per clock cycle. Since processors aren't laid out in straight lines this quickly restricts how large a single core of a CPU fan be. That being said, there have been computers that did what you're suggesting in a roundabout way: they put two multicore processors on ... |

Pizza theft by no payment | Most pizza delivery people take payment before they give you the pizza. On the off chance they do give it to you first, you'll be reported to the authorities and the pizza place will blacklist you as a non-payer. |
Why can't I eat or drink anything before surgery. | There was a post on the front page of imgur today that had a story of a mom who fed scrambled eggs to her daughter before a surgery.

Why do a good portion of severely autistic people hit themselves? | > I understand that they can't fully process everything that is happening, but it doesn't make sense for the brain to attack it's own bod It's kind of the opposite. They can't filter everything that is happening, it's overwhelming, so a predictable stimulus with a known cause and effect is calming. |

Why can't the Youtube app keep streaming in the background, unlike Spotify or other audio streaming apps? | I've never heard a good answer for this. Honestly, there's no technical reason.

Oil is barreled and sold to smaller distributers who bottle and brand the oil for retailers. So now, you've already doubled or tripled the shipping cost as well as the cost of packaging. 2) Oil... |
Why did we choose 360 degrees to represent a circle? | 360 can be evenly divided by more numbers. 2, 3, 4, 5, 6, 8, 9, 10, 12 shoot, every number from 1 to 12 except 7 and 11. That's pretty convenient. |
