Why do so many password requirements specifically forbid spaces? | There's no *technical* reason for this, and quite honestly I've not seen many password requirement that actually *forbid* spaces. Most password requirements will tell you want they *require*, and that will be letters and numbers and occasionally a *selection* of special characters. In the Olden Days, when password list... |
Can you guys help me explain to my friend that this isn't a nuke starting WW3? | It was just artillery hitting a munitions depot. It would be plastered on every channel that Russia did this and of course, Russia wouldn't nuke rebel territory", 'If it were a nuke there would have been reports of an artificial earthquake from Ukraine almost immediately. |
Why do cats freak out about cucumbers. | It's got nothing to do with cucumbers. Put something fairly large behind it when it can't see, and when it turns round it thinks 'something' is creeping up on it. |
Why do people say IQ tests (new ones) are biased??? | No one wants to seriously consider that different racial groups could have different IQs because that has lead to genocide in the past . So they create other explanations for why differences in performance never change. |
Why are there multiple stock exchanges when everything is done on computers anyway? | If stocks were all traded on one big market, the world wouldn't explode. It would probably work, but the idea of capitalism is that it wouldn't work for long. Derivatives are really good sometimes. The idea has been around for 2000 years but say a simple corn future contract didn't exist. If I created the corn future c... |
Why is height always used as a requirement to ride amusement park rides? Why not weight or age? | People already mentioned the obvious: the safety restraints won't hold you in place and there are people with uncommon proportions . There's also the fact that height is VERY easy to measure without any specialized equipment. All you need is a stick with a line on it. Weight requires a scale, age requires identificatio... |
What is the evolutionary reason for two genders? | Good answers. In addition to what's been said, I also like to think of sexes as an early form of work division. Specialization leads to increased efficiency, and even though it's obviously not relevant in modern times, back in the age of hunter-gatherers your sex was your profession. Having both sexes be equally good a... |
Why Moore's Law actually have predictive power | I think of it as working in roughly the same way that something like [Boyle's Law] works. Gasses are very chaotic things, and if you try to predict the path of any particular molecule in the gas, you will fail. It can't be done, because all the molecules are flying around and bumping into eachother all the time, and an... |
how do we fall asleep? | And after you ELI5, can you explain it to my five-month old? Because she doesn't want to ever!!", 'I still can't wrap my mind around how I actually slip into unconsciousness without actually realizing it. Every single night it happens, and I have yet to have a single "Aha! I got you now! You wanted to lose consciousnes... |
Why do (more) women not take birth control pills continually to never have periods? | As a female, even though periods are indeed unpleasant, they are also kind of a hormonal release and an indication everything is all good in the hood, know'm sayin? Men don't really understand the hormonal tempest that can swirl inside the female body. A period is the calm after that storm . Also the only time I have n... |
Countries whose habitants don't pay taxes: where does the money come from? | Oil. Saudi Arabia and Qatar are two countries that don't require it's citizens to pay tax. |
how can someone be allergic to water? | My Mom once had an allergic reaction to bottled water, but it wasn't the water itself she reacted to. She actually had a bad reaction to some of the minerals that had been put into that specific brand of bottled water. |
Why does the U.S. say "Merry Christmas" and the U.K. say "Happy Christmas," and when did this distinction appear? | There is little ELI5 summation because there are many reasons, but this is a good link, i'll include some excerpts after: _URL_0_ *What accounts for the difference? Queen Elizabeth, a woman of serious low-church piety, is said to prefer “happy” to “merry” because she dislikes “merry’s” connotation of boisterousness, ev... |
why we go TO work, and we go TO school, but we don't go TO home | home" is not a noun but rather and adverb. You're not saying a place where you're going, but rather something like the direction in which you're going, since "home" is not a place, but a concept - hell, "home is where the heart is". And you don't put prepositions before adverbs. [Here is a more lucid ELI5.] Edit: oh, a... |
Why does your stomach “growl” when you haven’t eaten? | Your stomach always growls, but when you have food in your belly you can't hear it as much, when it is empty you can hear it a lot more due to it being empty |
Why, even though New York and Spain are approximately 40° latitudinal, do they have vastly different climates? | Ocean Currents. Both are along the Atlantic Ocean which plays a huge factor as far as climate goes. The waters that comes up from the caribbean are really warm compared to those coming from the north atlantic that hit Spain's Atlantic coast. This warm water coupled with the jet stream that comes from the western US to ... |
Numbers Divisible by 3. | I'll try to explain using two digit numbers. A two digit number is worth 10 times its 10's digit plus 1 times it's ones digit. We'll express this as 10x+y. When we add the digits together, we have x+y. The difference between adding the digits together and the actual value is -=9x. 9 times any number is divisible by 3, ... |
Why is push-back from power utilities against solar power such a big deal? | Selling back is commented on well here. So I won't say more about it. Other tactics used are that the energy companies are making implementation so impossibly expensive that no one is willing to invest. Around my area, solar panels are taxed, which *GOES TO THE ENERGY COMPANY*, and they require expensive permits, on th... |
Why do I want to hold my penis while falling asleep/sleeping? | I read once that it's instinctual. Our ancestors slept on the ground where there are bugs and animals. The penis is sensitive and very important. They would protect it from bugs and animals by covering it with their hands while they slept. |
If water takes 2 days to be absorbed(because it has to travel to the large intestine) why do I have to pee after drinking water? | Sometimes your body already has too much water, and what happens is that your brain senses that you have too much water, and your brain stops releasing a hormone which tells your kidneys to absorb more water. This causes more water to be lost through your kidneys. Also, water absorption is very very fast. I don't know ... |
Why does salt water naturally exist on Earth and why is there so much more of it than regular fresh water? | It's the size of the pool. Dissolves ions exist in fresh water too- but just in very low amounts. When enough of it constantly flow into a a big pool of water you get more salty water. Sea water is only 3.5% salt anyway too, but the difference is, it doesn't flow away like fresh water streams could but stays largely in... |
Glasses and visual aids in general are a fairly recent invention. How did people with eye problems manage anything before then? | Glasses were a curiosity before the invention of the printing press. The only people who routinely had to read tiny little figures on paper were monks transcribing books. Unless somebody were really myopic, they likely wouldn't realize they had a problem with their vision. After the invention of the printing press, boo... |
Why is it so hard to de-salinize sea water? | The processes are well-understood; it's just that they are expensive in terms of energy. A nuclear reactor like those used to power aircraft carriers can generate power for purifying water - but the 150,000 gallons a day it can make are tiny compared to the water needs of the desert southwest. California uses about 38 ... |
How does legalizing a drug lower it's usage? | 1. When something is illegal, there is an increased desire to use it. Compared to alcohol, heroin is much less 'acceptable' to society because of their legal status, so the value of 'rebellion' or rejection of society for using heroin is much, much higher. That increased statement makes the desire to use heroin higher.... |
What does it mean when someone says that China is "devaluing their currency" | Your Currency, let's say it's the US dollar. Now: the exchange rate is: If you give $1, you get RMB 6.5. Forget it we'll call it the RMB. You have $1, and you give it to me, and I give you RMB 6.5 So let's say that you can buy a Coke for RMB 2. . . you can go to the store and buy 3 Cokes and still have RMB 0.5 TOMORROW... |
Why does social isolation screw humans up so badly? | A couple of things: lack of social interaction doesn't strictly imply you are only not speaking to people. It inherently implies something about your lifestyle. It would be hard to avoid interaction with people if you were involved in a diverse amount of engaging activities. If someone isolates themselves, stays in the... |
when looking up a song on youtube on my phone, why do all the results end up only being live versions? | Because they don't want you playing awesome music in your car. EVER. You used to be able to visit YouTube as a non-mobile site and that would work, not sure if you still can though.In this thread - mostly made-up explanations. Regardless of who uploads the song, YouTube is able to recognize the content and allows the o... |
Why the body (legs/arms) spasms sometimes when asleep or when nearly falling asleep ? | I think I heard that this is your brain testing to see whether your body needs to be used. If you respond to these spasms, your brain keeps you awake. Otherwise you fall asleep. Presumably everyone would respond differently though. To be honest, I have NO idea whether or not this is true, it's just something I remember... |
What happens when you press the elevator button more than once? | Especially crosswalk buttons are often placebo buttons that do nothing at all. Imagine if all the crosswalk buttons actually would have an effect - all the carefully planned traffic routing would be messed up constantly because traffic lights are suddenly out of sync etc. But modern humans love to think that they contr... |
Why does the UFC still use PPV? | It's a matter of deep vs wide support. UFC has deep but narrow support. What that means is that while most people aren't fans, the ones that do enjoy it like it a lot. That makes it ideal for PPV. Football has wide support - a lot of people watch it. That makes it ideal for advertisers. See, an advertiser just wants to... |
How do animals that camouflage themselves know what color are they? E.g. how do brown moths know that they are safe on brown surfaces and not white ones? | So I looked into the octopus and according to Scientific American, we flat out don't know. We know that they use their muscles to change pigments. Some think they are color blind and learn when a predator can see them and use retreat as a secondary defense. Others say that they use their arms to see and match colors. W... |
Why is it that TV shows can show vulgar images of sex, rape, murder, suicide, racism etc on TV shows but have to censor out the word Fuck? | Because it's fake, no actual sex or suicide occurs, and no actual blood is shown. Mr. Robot is TV-14, they could easily uncensor the cursing, but then it would get a TV-MA rating, which is very bad for viewership, meaning very bad for advertisers and very bad for the studio.Inappropriate words are pretty cut and dry, a... |
Can you detonate a bullet with blunt force? | the primer on a bullet contains a crystaline form of mercury fulminate. in a rim-fire bullet, this is in the base of the cartridge. to fire the bullet, you need to hit the primer hard enough to break the crystal of mercury fulminate, at which point it will spontaneously decompose, releasing a LOT of heat, which will th... |
What are the differences in the formations in soccer? | The formation you use is based on the type of players you have. I'm going to simplify this a lot but it's never this simple. Let's say you have 3 great Center Backs, 5 Great Mids and 2 Great Attackers. You're not going to use a 4-3-3 you're goign to run a 3-5-2 because that is what your personnel calls for. The type of... |
How are cell towers able to transmit different information to every cellphone as opposed to broadcasting everyone the same information when listening to the radio? | Basically all modern systems work by sending all the data out at the same frequency and getting the phone to only see the part of the data that is meant for it. Encryption means that you can't overhear someone else's data. The fundamental way this works is by having the phone and tower agree on some scheme by which the... |
On a coin toss how is the chance of getting Heads still 50% even after getting 4 Heads in the previous tosses. | > statistics states that out of the remaining 996 coin tosses on average 500 should be tails and 496 should be heads Statistics doesn't state that. |
Why do some people function better in the morning and other function better at night? | The circadian rhythm is endogenous. But it can be affected by light and dark patterns. Otherwise, I have no idea. I've always had a preference for the night and was a night owl until I had a kid. Now I have trouble sleeping past 6am since 6am isn't my bed time anymore. |
Why is it that diesel locomotives in North America seem to all have the same basic design, whereas here in the UK they come in a much bigger variety of shapes. | Just to add to what digahole said, Norfolk Southern and CSX are the biggest Class 1 RR's on the east coast of the US, and they're using mostly EMD's or GE's. . For some of the longer haul routes, you'll see a huge fuel tank beneath the main body, between the trucks . Big railroads will place a big order for better pric... |
- Why don't US Americans use bidet's? | I bought [this] and installed it about six months ago. I don't think my girlfriend has noticed it yet. That type of bidet sprayer were all over the place in Dubai. The only other kind of bidet I'm used to are the ones I had living in Italy [like this] and I can't see many Americans figuring that kind out on their own. |
I've heard the term "Chapter 11" used frequently in the context of bankruptcy. What specifically does it refer to? Is there more than one kind of bankruptcy? | Yes, there is more than one kind of bankruptcy in Title 11. The most common ones are Chapter 11 where a company tries to get it's debts changed but stay in business, and Chapter 7 where a company is liquidated.Chapter 11 is a chapter of Title 11 of the United States Bankruptcy Code, which permits reorganization under t... |
Why are CGI effects so expensive to produce, when they are a virtual tool, that seemingly only requires software? | CGI Effects don't have to be expensive! Check out the cheap CGI in lots of low-budget B-movies. However *good looking* CGI that can pass for real is very expensive as it requires very skilled artists a long time to make. Just because these artists work exclusively with software doesn't mean they don't need to paid. Goo... |
If I were to drop an insect from the Empire State Building would it survive? And how do beetles fall off a height and survive that people can't? | Two reasons. One, things that weigh less have a small terminal velocity, like a feather, it will never accelerate past a certain very slow speed. Second, the square-cube law. The structural integrity of an object is determined by its surface area, or x^2, but the weight, ie, the stresses that will be put on it, is dete... |
why Europe has 230volts and US has 110V? | No real reason. Early electrical generation was very local, and everyone did things a little bit differently, even within a country. Electrical appliances tended to be large and fragile, so there wasn't a huge expectation people would be moving them from place to place. By the time people realized the problems with hav... |
I went on a 5 day drinking binge, and was never more exhausted in my whole life yesterday, yet my body refused to let me go to sleep | To put it simply, abruptly stopping extended heavy alcohol consumption can result in alcohol withdrawal syndrome along with insomnia. Alcohol really messes up your brain's chemistry. While still maintaining an alcohol fueled diet, again alcoholism, it takes more time to fall asleep. I got my answers from [here].I like ... |
Teeth grinding at night and how it can be so loud. Also how can our jaws clench that hard unconsciously but not awake? | I have to wear this two piece night guard that has a titanium spacer to keep my top and bottom teeth from touching. I had a sleep study and they found I was clenching down so hard while sleeping that I would actually stop breathing. Fortunately my appliance was covered under my medical insurance since the diagnosis was... |
Can firearms function in space? | Interesting factoid: The Soviet [Almaz] space station had a 23 mm autocannon, to test the use of this sort of gun for use in self-defense. It was actually test-fired at the end of the station's mission, and as far as I can tell, is the only recorded instance of a gun fired in space. It gets kind of crazy when you think... |
How do all political cartoonists have the same art style and handwriting? | If it helps any, the handwriting is a typeface at this point. And it is difficult to learn to stay inside a certain art style's rules, but once you learn the rules, it's easy to make them bend and contort into your own style. So it's a lot of practice and using a computer to include the text. |
Why does the Gambler's Fallacy hold true? | Ok, here's another way to think about it that might help. Say you have a coin and you flip heads . Is outcome is just as likely as if you'd flipped tails . Let's say you flip again. You flip tails. Because tails and heads are equally likely, the chance of this is 25% , identical to two heads in a row . One more flip an... |
Why does filming someone on the street when they've asked you to stop not constitute harassment? | In the US the act of filming is protected under the First Amendment as free speech, and is legal as long as the person's privacy is not being violated. If they use the video for commercial gain or upload the video to the internet, on the other hand, it could become illegal in certain jurisdictions. Note that this appli... |
If there have already been 2 unsuccessful NFL teams in L.A. why do Dean Spanos and Stan Kroenke think that it will work now? | It is a fair question. LA is the second biggest city and media market in the US, and its cultural influence is behind perhaps only NYC. By the numbers, it *should* be able to support two football teams. However, unlike other big cities, it is highly decentralized. It is less a city with suburbs, and more a bunch of cit... |
What is the weird tingling feeling people often get when they watch ASMR (or other things) | I get the tingling feeling, but for me it presents itself in ONLY my right kidney. It's really weird.Pleasant tingling in the top inner scalp and at the top of the spine. Def not sexual but alot of youtube channel's have taken it that way, its hard to explain why you watch people talk on your computer but its way easie... |
Why do westerners prefer black tea while Asian countries prefer green tea? | Asian countries don't prefer green tea. I don't know where you get your information. I grew up in an Asian country and have visited many others. Black tea is the most common choice when it comes to tea.Japan != Asia. Most of the traditional teas drank in the rest of Asia is black tea I think you are mistaking your own ... |
Does substituting the recommended 8 hours sleep a night for 5-6 hours and a cup of delectable coffee in the morning have any long-term side effects? | For 2 years or so I could go to bed at 1am, wake up at 5:40am, and occasionally get a 1 hr nap from 8-9pm. So, 4:40-6 hours a night max. I could function just fine, but I required the weekends to make up for it -- I would sleep 9-10 hours Friday night and another 8-9 Saturday night. On Sunday night, I often would only ... |
Why, at least in the United States, is it common to say "Merry Christmas" despite saying "Happy ___" for other holidays? | You've gotta bet it was furiously popularized by the distribution of holiday cards - in particular, Hallmark. Traditionally, greeting/holiday card companies standardized the phrases they would use for certain holidays and then just switch up the visual design of the cards. So they helped. They aided in popularizing the... |
How do cars float? | It's the same reason why much, much, much heavier ships float. can displace over 500,000 long tons) Air is very good at keeping things afloat and you don't need a lot of it to offset the weight of a car, because air is a lot less dense than water. |
How does the UK justify that they have a reasonable claim over the Falkland Islands? | They weren't actually there first, New Spain was, then they withdrew from it during the peninsular war, which resulted in it going to British hands. The claim is strengthened by the fact that Falklanders overwhelmingly wish to be British instead of Argentinian, and Britain's military might further strengthens the claim... |
What is "The Cloud"? I understand it's internet storage, but who runs it and why should I trust it? | Say you have a portable hard drive. You plug your laptop into it using a USB cable and you save a file to it. That is the regular way of saving files. Now instead of using a USB cable to transfer the data, you use a wifi connection. That's the cloud. The advantage is that say you have 10 people all working on one docum... |
Why is it okay to drink Everclear but it isn't okay to drink ethanol? | Industrial ethanol is specifically poisoned to ruin it for consumption, a technique that goes back to the Prohibition. One reason is that there's separate higher taxes on alcohol intended for consumption. Methanol is commonly used for this poisoning, but other substances are used, too. In the body, methanol turns into ... |
How is it that once outside our body fecal matter is harmful/infectious, but when it's still in our bowels it isn't? | It still is harmful when it's inside of us, it's just in a self contained tube that prevents it from reaching other parts of the body. |
Why does the US use commas and periods differently on currency than other countries? | Marking decimals was a complicated business, but in the middle ages Arabian mathematicians began using a small mark between the units and the tenths. It was a very short vertical line written below the text baseline, and to some people it looked like a dot while to others it looked like a comma. When French mathemetici... |
why perpetual energy doesn't work? | Laptops _consume_ energy. Others here mentioned losses as heat and all, but _even if the cable can transfer electricity without loss_, how this is setup any different from having your normal laptop on a battery? Any energy from the USB comes from the battery, and any energy going in the charger comes from the USB. If t... |
Have any governmemts made any serious attempts to come up with ways to deal with an alien invasion? | If they had evidence that one could occur, I'm sure they would. At this point, a Zombie apocalypse, or a massive Unicorn stampede would be just as likely a scenario. |
Why do video games have to be ported for different OSs? | This is kind of like asking why can't you just put a human brain in a robot body. How the brain expects the body to be controlled could be completely different. The brain is kind of like the software in the above situation and the robot and human body are like two different operating systems The OS supports the softwar... |
Why is Chinaman considered racist while Englishman, Frenchman, Scottsman, etc are not? | I'd say it's because Chinaman was historically applied to other asian people who are not actually chinese, whereas the other descriptors were/are usually only used in the corresponding cases. |
Why are Americans so patriotic? | We are still riding high from the last century of kicking a ton of ass in multiple fields, Many world changing things have come from the US, plus its been ingrained into us from birth. We may not be in the best spot right now, but I cant think of a country I would rather live in, and I'm not even overly patriotic. Also... |
Why haven't we started using nuclear energy to generate electricity at a large scale? | Because there are several concerns that still have to be answered for it to be somewhat safe and reliable. The main problem here is the storage and/or disposable of the nuclear waste that is left over from the fuel that enters the factory. Right now, some plats bury it deep underground in special containers that don't ... |
What exactly are those people at the doors of Walmart checking on your receipt? And can they legally stop you from leaving after you have already paid for the items you are leaving with? | This typically only with membership stores like Sam's and Costco. Then can do it because they put it in the membership agreement you sign. You could legally walk out, and the could legally terminate your membership. |
How did the ice cream truck come to be? And how do they stay in business if they only sell product in the summertime? | Food stands/carts/trucks have existed as long as markets have existed. People want to sell their food, they haul it to a market and sell it. Live chickens hanging tied up from cheap wooden stalls in markets have been a thing as long as animal husbandry. When portable refrigeration powerful enough to freeze water was in... |
Why does everyone hate Lena Dunham? Can anyone give me a simple timeline of her reputation tanking? | This is a hard one to answer objectively because everyone has different opinions about what's ok and what's not ok, but here's a non-exhaustive list of the things she's said and done that many people find inappropriate or distasteful in no particular order: * Her show, *Girls* was very white, there were only a handful ... |
Why does FM stations starts at 86 to 110 rather than other numbers? (Atleast where im from, SEA) | Also different countries use different settings we import a lot of cars from Japan and you can't use any station but 88.5. |
Why do dogs have different breeds with very noticeable differences, while cats appear to be pretty much the same just in different colors? | Do you even cat fancy? There's a world of difference between different breeds of domestic cats. You can get as small as munchkins, which are bred to not have lower legs and not get much bigger than a kitten, all the way up to maine coons that can hit 25+lbs on average. Short hair, long hair, no hair. Not to mention the... |
How is renewable energy more feasible than the alternative if it relies upon rare-earth materials? | There are strategies for renewable energy that don't involve batteries, such as flywheels, or using available energy to pump water up a hill, and then using that to generate hydroelectric during peak usage. Plus there is a lot of active research in batteries. There's a good chance we will invent a better battery soon t... |
Why do we have to install games on this generation of consoles before we play them? | Games are getting much bigger, and for many, especially big open world games like GTA, the amount of stuff that the game has to load in is just too much to do from the disc. Forcing the user to install ends up decreasing load times a ton. If the game didn't force you to sit through that initial install process, and ins... |
Why is Kayne West such a controversial figure ? | Kanye West is controversial because enough people view him as erratic enough to ask why he's so controversial. Besides people's unwavering interest in celebrities, he's just a narcissistic drama queen, whom I suspect has extreme delusions of grandeur, and he just happens to have a lot of people's attention. Humans are ... |
Why don't people just run away when they get in trouble? | Even more serious question: Why do criminals actually brag openly about crimes on social media? Same answer as op: Criminals on average are stupid. The smart ones you don't hear about them, because nobody knows about them.They do, all the time. That is why people who are at high risk do not get offered bail and are hel... |
If time was paused while music was playing, would the note being played at the time of the pause be constant, or would the music drop and silence ensue? | I'm no scientist, but assuming that everything stops moving, there would be nothing vibrating in order to make sound waves. Right? |
How and why are bowels able to create such audible sounds? | It's gas production in the intestines. They get louder the more empty of solid mass they are. In most people, they all but go silent when you eat and get progressively louder as you approach the ext meal time. That's how you get the stomach growling sound. |
Why are so many people against background checks for purchasing weapons? | In theory, people don't support background checks because they can be tied to a registry and thus confiscation. In practice, legislators won't put a bill through committee that doesn't also have a ton of other amendments that do not simply provide for background checks.As others have noted, "so many people" are not nec... |
What do they mean when they say Jupiter is a "gas" planet? Could a rocket be shot through it? Could an astronaut (or spacecraft) "land" on it? | No. Although Jupiter is indeed comprised of mostly gas, specifically hydrogen and helium, at the pressures that you would find near Jupiter's center, the gas does not behave anywhere close to how it would behave on the surface of the Earth. There is very likely no solid core with a surface that could be landed upon, bu... |
How do multi-day freeclimbs work in rock climbing? How do you get ropes above you to catch your fall? | Climbers carry the rope up with them and attached it to the rock face as they go. There are two approaches : In sports climbing the rock will have metal fixtures drilled into it that they can clip the rope into. The climber will have one end of the rope attached to themselves and the other to the belayer*. Whenever the... |
Is crooked teeth an advantageous trait in humans? Is wanting "Straight" teeth purely a cosmetic desire? | Traits we get through evolution do not necessarily have to be an advantage, they can just not be a big enough drawback to be an evolutionary factor. Man having nipples, as another example, have no real survival/reproductive value, but they won't get you killed, so the genes for them don't get sorted out. |
Why do all soldiers wear camouflage nowadays? | It's better to fight in camouflage. It makes you harder to see which makes you less likely to get shot. Most militaries also have dress uniforms or alternate work uniforms.The current reasons for use camoflague should be self explanatory. Militaries these days can effectively command and control units through radios. A... |
What causes 'speed wobble' while riding bicycles/skateboards etc. at high speeds | Lifelong skateboarder here that did downhill longboard racing from 2009-2012. Skateboards wobble because you're constantly standing with all your weight on the turing system which is only restricted by 2 little bushings in each truck. With little experience, for what ever reason, if your truck goes into a turing dive w... |
How does an ebrake work/how is it useful if you can still drive with it engaged? | It's worked for me. Last week with heavy snow fallen, I drove home. A truck in front of me stopped all of the sudden and I had to hit the brakes. I was sliding and I was not stopping because it happened too soon. I pulled the ebrake and it stopped me completely. I did not hit the truck |
Why isn't waste just melted down and poured inside a volcano. | Sadly, lava does not work like minecraft lava in real life. I've checked too. :( |
Why do people think it's racist that there are no black actors in the Oscar nominations, but not that there are no white people on the NBA All-Star team? | Member of a sports all star teams is mostly objective. Sure, you can argue whether someone is the 12th best player or the 15th, but the pecking order is usually pretty clear. Oscar nominations are much more subjective, and that gives people more opportunity to exercise their biases, and be accused of biases even when t... |
Why is it sometimes easy to peel a hard-boiled egg, while other times the shell sticks and fragments into bazillions of tiny pieces? | I know it's much easier to peel eggs if you hard boil them when they're a few weeks old. Hard boiling fresh eggs makes for difficult peeling. I'm not sure why this is, but my grandmother taught me this and she was right. Hope this helps.As a rule, the fresher the egg, the more difficult it is to peel cleanly. The album... |
why is it such a big deal when someone falls asleep after a concussion? | It's basically a myth/urban legend at this point. There's nothing dangerous about sleeping after a possible concussion. The only reason you wouldn't want someone to sleep is so you can monitor them and make sure they're alright. A sleeping person can't tell you how they're feeling and you can't check their pupils or se... |
What exactly does it mean that the N64 runs on 64 bits? | A 32 bit computer stores most numbers as 32 bits. This gives you a range from 0 to 2^32 -1 to use. You'd probably think that 2^32 is an enormous number and you'd never need more than that.

This prediction video—it outsmarted me. Is it possible to win? | It's a trick of logic more than anything else. By moving an odd number of spaces in each round, there are some spaces that it's logically impossible to move to, like a bishop on a chess board. |
Laws that require you to prove you're 21 (or other age) if you're under age X | X represents the apparent age at which even an inaccurate guess would put you over 21. If X is 35 and I judge to be that old, I might be wrong, but I am probably not 15 years wrong. It has provides some cover to cashier and bartenders, who want to comply with the law, but don't want to hassle senior citizens. |
Could allergies eventually by phased out by evolution / natural selection? Or do genetics play no part? | Regardless of whether it's genetic or not, no. Natural selection only works when people with or without certain traits straight up die without reproducing. As long as there isn't some huge event of worldwide eugenics, there will continue to be more and more genetic *defects* entering our gene pool. If anything we'd be ... |
What happened to Gandalf the Grey in Fellowship of the Ring? Why did he come back as Gandalf the White? | I just want to say that this is the most thorough and well thought out discussion of a two sentence question that I've ever seen. Well, well done folks. |
The universe is constantly expanding. Well what is it expanding into? | Imaging a 2d world where we live on the surface of a balloon and some energy is causing the balloon to be blown up. Of course the balloon is 3d while we are 2d. So we can think of the surface of the balloon as never ending, as we have no concept of the 3rd dimension so can't look at the balloon as a balloon rather we s... |
Why is it not okay to pet guide dogs? I mean, those dogs need love too. | Guide dogs are working dogs, and petting can distract them.

Some guide dogs are also highly protective of their humans, and cou... |
Why is it, in China, when horrendous crimes are being taken place, pedestrians just keep walking? | This is actually a pretty complex issue that must be understood in a legal, historical, and cultural context. As /u/faloi points out, [Good Samaritan laws] haven't typically been around in China . Basically, you could be sued for helping someone if you're unqualified to do so. Since most people aren't doctors, it is sa... |
How can my phone with a 5 inch screen be 1080p, but my TV which has a 55 inch screen hot be 11 times the resolution? If that makes sense. | Pixel density.

If you walk up to your TV you will see the individual pixels. There are TV screen with higher number of pixels, for exam... |
Why can't we do like a hundred airstrikes a day against ISIS | Ex-military intelligence analyst here, The limiting factor for air-strikes is identifying targets. If they know where a target is, and the target is going to be there by the time the airplane shows up, they will bomb it. However, people are very poor targets, since they tend to move around and be around other people we... |
Why is Tony Abbot, Former Prime Minister of Australia, so Loathed? | From what I've read, he was a very conservative leader and Australia is becoming more progressive so his leadership ideals directly conflicted with what the people wanted as their country moves forward. |
Why are bathrooms all gender specific, rather than having one restroom with all stalls, for both genders? | Also, women deal with menstrual products in bathrooms, and as a teenager, the sound of opening up a pad was loud, I probably would have been very embarrassed if a man heard that.
