Why does unplugging and plugging back in a device work so well with troubleshooting? | Imagine you're playing a game of chess and in the middle of the game you realize both bishops are on the same color. You don't remember which piece was which, and you don't know how many moves to go back to fix the problem, so the only solution is to return all the pieces to their starting positions and start again. |
Why do songs always sound much better in films? | It's often because they very slightly alter the speed of the song to match the scenario in the movie, they also EQ the track to sound 'more cinematic', There are other tricks at play as well sometimes they can cut out the more boring parts of the track so you are only hearing the best bits. There is also the fact that ... |
Why whenever I'm sleeping in a car ride home, i wake up right before i reach my house? | It's all that screaming from your passengers right before you drive through the garage door.I used to live in New Jersey and had to commute into Manhattan for my job. For years I had to take the bus and I 'd often fall asleep on the ride back home. And yet I never once missed my stop. So I started to wonder the same th... |
Why do animals sometimes just let us do what we want with them? I.E. Picking cats up. | Just wants to say that my cat loved being carried, it was the snuggle train where he had the superior view and didn't have to walk, and when he had enough he just jumped off. You make it sound like the animals does not get something out of it, many of them are social enough to like the treatment of attention.My cat lov... |
How do companies know not to use the same barcode on different products from other companies? | There are over a million unique UPC's in the controller of the grocery store I work at. Not all of them are active, but they are there. |
How is it legal to post a persons image on the internet without their consent | Television only has to blur someone image if the picture or video is being used for commercial purposes. Many reality shows will blur the image of anyone who doesn't sign a waiver just to be on the safe side since one could argue that a reality show is a commercial venture. News shows do not have to blur the image of a... |
why multivitamins have over 100% DV of certain vitamins and minerals. | From what a friend of mine tells me is that the main reason they put extra vitamins and minerals is because your body doesn't always manage to absorb all of it, so by adding extra it helps you hit your goal of 100%. Vitamin B I believe helps your body convert carbohydrates into energy quicker, that is why it is loaded ... |
Why do clocks often make two alternating noises (like "tick" and "tock")? | Mt grandparents had grandfather clocks when I was a kid. I used to listen to them as well, I usually didn't have much else to do. It was only after I'd phase out that it stopped bein tick tock and would be all ticks or all tocks which always led me to believe the sound difference was an illusion. |
Why can't satellites be used to search for aircraft crashes? | I can't wait for NASA's facebook page comments to be full of this again for the next month. Same rubbish happened during the Malay Airlines crash. |
Why do animals of the same race/species look very identical but humans, same or not of the same race/species, look different? | Individuals from a particular species are better recognising individuals from their species rather than individuals from other species. Recently I read about a face recognition test on chimps. They were faced with photos of humans, testing them to recognize their faces, as expected, chimps did poorly, they were as good... |
Why (or how) do SSRIs make people feel suicidal? | Typically, not always, the issue is that they were suicidal before, but depression made them unmotivated. So the medications help with the depression, but not the suicidal thoughts. So now they're motivated enough to kill themselves. |
Why does putting frozen meat in very cold water defrost it fast? | Water transfers heat much better/faster than air. Metal is also a good conductor of heat, so placing something frozen on a slab of metal, will defrost it better than putting it on a plank of wood etc. I remember an infomercial product that was supposed to be a 'miracle defroster' or something like that. It was just a m... |
what does the freezing of hiring federal civilian employees across all boards of the executive branch mean to the average young American adult? | IT means you aren't getting a job with the Federal Government for awhile unless you work in the defense sector. It also means any interaction you have with the Federal Government will likely take a little longer.It means there will be an increased cost to the government resting in unnecessary debt, reduced efficiency o... |
- Why Gandalf chose Bilbo. | Because Tolkien wanted to write a book about someone ordinary who finds inner strength when thrust into extraordinary circumstances. The in book explanation is that Gandalf is super wise and his intuition told him Bilbo was the right person for the job. This is a common theme in storytelling. Usually the reader accepts... |
Why do hiccups disappear when someone shocks you? | When my husband and I started dating, he taught me his method of making hiccups stop. Breathe normally, and concentrate very hard on the next hiccup, wait for it. 95% of the time it works, but it takes practice. My husband never hiccups more than twice, the only time it doesn't work for me is on those days when they're... |
How can so many mobile games be blatant ripoffs of games belonging to larger, more successful companies without their makers being sued into oblivion? | Others have commented on not being able to patent a game. They're totally right There's also the aspect that it can be not worth the time/resources to strictly track down every single illegally copy . Its expensive to sue,if you can even find them.or they may be in a country like China which makes it harder to sue over... |
How is milk made biochemically? Do we understand it well enough and have the means to make it artificially (either cow or human milk)? | Milk is basically water that has proteins, sugar, fat and salt added to it. It is created by epithelial cells arranged in glands . The glands then release it into the ducts. I'm sure we could make it artificially , however it is significantly cheaper to get it from cows. |
Why are books better than other forms of media? | Though there are exceptions, movies are generally pretty expensive to make and distribute . So studios usually want as many people as possible to watch their movie/show. Quite frankly, the average person just isn't that intelligent, and the average show/movie is usually something that can appeal to 'everyone'. Even if ... |
As a foreigner visiting the U.S., I couldn't help but notice how there's insurance for everything here. Why is this? | It's a catch 22 situation. Take Health insurance. You need health insurance because the price of anything for health is very expensive. Why is it so expensive? Because it's paid for by insurance companies so the health companies charge higher prices, and because the charge higher prices, you need insurance. |
Stocks are down worldwide (apparently as bad as the 2008 financial crisis). What does this mean for your average Joe? | This is nowhere near as bad as the financial crisis. From peak to trough, the S & P 500 declined by 55% during the financial crisis. It lost literally over half of its value . So far in this latest episode, the S & P 500 is down 11% from its peak. It's scary but it's *worlds apart* from the financial crisis. |
If WhatsApp chats are encrypted then how Facebook is going to collect data from WhatsApp chats for targeted advertising? | Only the actual chat contents are encrypted in transition. So if Person A is chatting with Person B, then texts that they send each other are encrypted. But Facebook can still use the fact that A is talking with B, how many times and when they talk, where they are located, whether they are friends on facebook, etc. It'... |
How was cursive handwriting invented? Why was it ever considered important? | Modern cursive handwriting using pens developed out of the script used with quills, which itself had an evolving script that evolved out of writing methods like wax tablets. For someone intimately familiar with it, cursive handwriting is faster than using block letters. Good handwriting reads as well as print if you're... |
How do horse racing odds work and why can some work out to 3-5, where you can only lose money? | 3-5 odds mean with $5 on you'd win back your original bet plus $3, so $8 altogether. You'd have to be pretty sure of a win to bet at those odds. |
Why in the US cops can kill and people are allowed to own guns and kill too in self defence? | > In Europe they can't and it's a lot better. Its better due to the lack of guns, not the lack of ability to kill in self defense. Cops and citizens cant just kill however they see fit. Most of the problems we have with guns aren't due to any self defense claim. Cops and people can shoot to kill in order to save their ... |
What exactly is an ethical dilemma? | I presume that the question is asking you to find a situation in which there is a difficult choice to make, and that this decision is in a morally grey area in the sense that it is hard to tell what the 'right' thing to do is . An example would be whether to end a person's life for them when they are suffering a lot. S... |
How did they get the background to move in "The Max Headroom Incident?" | Gonna guess it's just a metal sheet attached to a swivel that someone is rotating back and forth. It looks like whoever is smacking Max on the ass at 1:40 was the one moving the background since it stays still from that point on. |
Why do only people in the military widely use 24-hour (Further than 12)? | It's true only for USA. Think about other countries around the globe. Here in Argentina, for example, we prefer the 24-hour format. The 12-hour is bound to the old mechanical clocks, so it is mostly an inherited tradition than an effective way to tell the hour.almost all countrys in the world use 24 hours not just mili... |
Why do we associate the color white with "plain" and "empty"? | For some people. White is the lack of colour. Black is technically all colors combined but white is pure and lack any impurities. That's why you can't ever make something white unless it already is, but you can make black from many sources. It's all about pigments.If you do it's because it's the most commonly used colo... |
Why is "IZombie" able to talk about copyrighted material like "Warm Bodies" and "Sons of Anarchy" | Plus it's not really uncommon on genre shows. Buffy used to mention things like Bond and Star Trek all the time. |
Why does human and livestock feces contaminate/pollute rivers when fish and native species also poop near or into the water? | > fish and other animals have been pooping into the water and they've been drinking that with no problem for thousands of years Animals in the wild are generally less healthy than humans in cities. If you lived with the same level of sanitation, your life expectancy would drop significantly. It's like how an indoor cat... |
Why are revolver type pistols still popular during our modern time? what advantage do they have over clip based more modern designs? | Throwing in another reason that seems to be overlooked. Cost. Revolvers have fewer parts, and fewer moving parts, requiring less precise manufacturing techniques. I'm exaggerating, but it's basically the same reason we still have screw drivers even though power drills are better. |
Why are movies still shot ~30 fps and not 60 or more? | I believe it's mostly for aesthetic reasons. The higher the frame rate the more realistic the images appear, 24 fps gives video what you would call the cinematic feel to it. If you film with a point and shoot camera you get roughly 60fps , if you were to watch a film in that kind of footage you'd probably be rather uni... |
Why can't I eat or drink anything before surgery. | Because they don't want you throwing up while you're unconscious. If that happened, it'd be easy for you to inhale some of your vomit into your lungs, which is generally a bad thing. It's tough to deal with that in a person that's been put under, because their body might not respond appropriately to clear the lungs. |
Why does it seem like my body will "wait" until I have time off then I get sick | Hans Selye's GAS. General adaptation syndrome. It has three stages. Alarm, resist, and exhaustion. When you work hard and stress build up at work, you resist. Once your body has experienced enough stress or work you enter exhaustion.Cloverfield. Actually everybody else in the theatre felt the same way, and a few guys b... |
Why did we choose 360 degrees to represent a circle? | While the true reason isn't known for sure, the wiki states a few theories. It could have been to match the number of days in a year in the Persian calendar. Or it could have been from Babaloynians who used the number 60 frequently in their system, representing circle measurements with six equilateral triangles, each o... |
If corporations are moving to different countries because the U.S. tax system sucks, why do politicians blame the corporations and not the U.S. tax system? | Some of these answers are well thought out but miss the point. Companies are moving abroad because labor is cheap, period. They say it's taxes because it benefits them, but that is simply not true. Tax what you want, can't beat $5 an hour labor.Because "The U.S. tax system sucks" grossly oversimplifies the situation. T... |
Do I really need an oil change every 3000 miles? | I run a F150 as a daily commuter and beat the hell out of it on unpaved mining/oil roads all summer long. I try to change it every 5,000k but usually get up closer to 6k due to procrastination. If you're running a newer full synthetic in a car, I don't see why would couldn't hit closer to 8.5k But I'd keep an eye on th... |
Why aren't there many movies when the bad guy wins? | You need to watch the Usual Suspects. Or Momento. Or No Country for Old Men. Or There Will Be Blood. Or The Wicker Man. Or One Flew Over The Cuckoo's Nest. Plenty of movies in this genre out there. |
why are camera lenses round but the pictures rectangle. | Round lenses are much easier to make. It's simpler to make a round lens, and only capture a rectangular part of the image formed by it, than to make a rectangular lens. The unwanted portion is absorbed by black painted areas inside the camera. |
Why do I get lightheaded when I stretch my body? | As others have said, changes in your body's blood flow while stretching can contribute to lightheadedness. This is worsened if you are dehydrated. I suggest drinking more fluids throughout the day . You are the most dehydrated in the morning after going without any fluids for 8 hours of sleep, so drink a nice big glass... |
Why are anti-virus programs pretty big in size? | Something to keep in mind is that Antivirus scanners don't *need* to be very big at all. I use Webroot Secure, which takes up a little less than 6MB. |
What is an engine then, really? | Finally joined reddit to answer this question. It is most definitely NOT an internal combustion engine. It is a compressor, likely for air conditioning or a cooler of some sort. Carrier makes HVAC equipment, not engines. It's meant to be driven by either an engine or an electric motor . If there's a walk-in cooler in t... |
Why does it take several years for human babies to fully develop control over their bladder and sphincter muscles? | Related medical question: Is it that human babies cannot control their bladder and sphincter muscles, or is it they don't know that they're supposed to? |
What is laughing and why do we do it? | Laughter, at it's core, is a natural reaction to avoiding death/danger that evolved in order to alert others in the tribe that you are alive and the area is safe. This is the reason we find slapstick humor so funny. Simple things like a pie-to-the-face, or slipping on a banana are funny even to chimps, because they als... |
Question from an actual 5yo: Why don't we let the smart monkeys live with us? | They're not like dogs or cats which have been domesticated over a long time, they're still wild animals. They're usually far stronger than a human and can be quite dangerous. Houses are our natural environment not theirs. Jungles are what they understand so unless you have a lot of expertise, time and money to manage t... |
Double Jeopardy, Can it be overturned if obvious evidence is produced? | Not unless there is judicial misconduct involved, in which case the first trial is declared a mistrial. While it might seem unfair, society is in far more danger from an abuse gov't trying people over and over for the same crime until they get a conviction, than they are from the occasional murderer going free. |
How do we manage to communicate with space shuttles and other objects that are SO far away? | For any sort of radio communications, you are dealing with a [Link Budget problem.] Essentially, you add up all your things that boost the power of your communication signal, then subtract the things that cause losses, and if the amount of signal you are left over with is far enough above the ambient radio noise, you c... |
The Baha'i Faith. | I am a an 8th generation Baha'i, so I hope I serve as at least a somewhat reputable source of information on the subject. The mentions of anti-homosexuality I've read in these replies need context. The Baha'is as a general rule do NOT view homosexuality as sinful. Sin as a concept doesn't actually play much part in the... |
Will eating only one meal a day have any long term effects? | You are just fasting. Probably quite extreme fasting but it shouldn't be bad for as long as you get enough calories. It's pretty hard to eat one ~2500 kcal meal though. |
Why is it so difficult for some people to remember how to do simple "computer things" even though they've been shown it dozens of times? | Chances are, they have no other knowledge about the field. If you're familiar with computers, operating systems, browsers, tabs, search engines, email and whatnot, it's simple to expand upon that existing knowledge. In contrast, if you don't know anything substantial about the systems in place, it's hard to remember fr... |
Why isn't there a flat tax rate? | Taxing people more or less based on how much money they make has nothing to do with fairness. It's about collecting MORE taxes. It's simplest way for the government to collect more money in taxes without making too many people angry. Just because something is equal, doesn't necessarily make it fair. |
Why do so many Pagan/Polytheism religions have so much in common even when the cultures never or rarely interacted? | In terms of types of gods, it's because they draw upon elements commonly found in nature. The most common example is the sun god. The sun creates light, day, helps grow food, etc. So back when food, and general survival, was completely dependent on the whims of these natural aspects, of course someone would start to th... |
Why are gay men generally effeminate? | Can't explain that because I'd dispute your base contention. *Some* gay men are effeminate but many aren't. |
Why can a page take forever to load but as soon as I close it I catch a glimpse of the completed page? | I really wasn't expecting a legit answer to this problem. I always just thought the world hated me |
Why is it considered unsafe to refreeze food that has been thawed? | It's not actually unsafe, but there were concerns that people would lose track of how long it had been in the thawed state, than frozen. Of course, what really matters is how long it's been warmed up for. And keeping track of that can be tricky - for a start it depends on how you warm it, where you warm it, how fast yo... |
How hard is it to implement a global standard of 120V or 240V? | Actually I think the choice is now between 115V and 230V. The nominal standard in Australia changed just a few years ago from 240V to 230V and I believe it's part of a global standardisation move. As for how hard it would be to choose one or the other, the answer is that the cost would be much more than any benefit. Th... |
Why are completely unrelated issues (like abortion) able to be tacked on a bill about an unrelated issue like motor cycle safety to be voted on? Why is this legal? | The congress has complete authority under the constitution to decide how it passes it's own bills short of a couple provisions . They decided not to make it illegal to combine multiple issues into one bill so that's the way it is. If they wanted it to be illegal they could make a law to do it. |
Why is the MI6 building located in an open area where it is prone to attack? | It has already been attacked with terrorist firing RPGs at it. They didn't do any damage; _URL_0_ I had the chance to go work there once but decided against it because the pay was shitty and I don't like London. Moved to Australia instead.Ever heard of kill zones? On open area with no cover that must be crossed to reac... |
Why are americans so obsessed with dinosaurs? | Because we're stupid and like things that look like real life monsters? Wtf? Do you honestly think Americans alone have a fascination with dinosaurs.. I'm wondering where you developed this idea. |
Why can phones make such a loud noise for an amber alert? Why can't they normally go this loud? | Assuming you're talking about the 'emergency alert system' tone that sound is just two sine waves mixed together. A sine wave is a pure sound consisting of just one frequency at a constant volume. This will sound louder than music, which is a complex combination of many different frequencies. Plus with music, the dynam... |
How much information does the IT department have about what their coworkers are viewing during work hours? Are there any privacy laws or can they tattle on me? | Sysadmin checking in. We can find out, we will find out, but we dont care until someone asks or complains. do your shit at home on your time unlike me who's playing on reddit ", 'How much information depends a lot on the company and how everything is set up, but it is safe to assume that have access to most if not ever... |
How did it take 100 years to discover the happy birthday copyright was invalid? And do they have to repay the people they collected royalties from? | It's also worth noting that whether or not the copyright was invalid isn't relevant to the situation. Large companies have been known to use their legal departments to bully their way through things that they legally cannot do. If you sang Happy Birthday in a movie and someone threatened legal action, claiming to be th... |
How is College Board(SAT test company for the US) not considered a monopoly | They don't have a monopoly on making standardized tests. They have a proprietary test, but so long as they aren't actively preventing competition from producing tests, they aren't doing anything illegal.Others have said "they're not a monopoly". But I 'd like to add that it's not illegal to be a monopoly. It's illegal ... |
Why everybody hates
Hipsters? | I'll re-post some copypasta that I found a while ago, don't know the original source, but it should be interesting in this thread: > “Hipster” is a term co-opted for use as a meaningless pejorative in order to vaguely call someone else’s authenticity into question and, by extension, claim authenticity for yourself. It ... |
ELI: Difference between "legal" and "decriminalized"? | I don't know what other people are using as sources, but they don't seem to be very clear. First, it's important to recognize that some terms, like misdemeanor, have different meanings for different states. These meanings also may be different for other countries. My explanation here doesn't run into this problem. Lega... |
Why is Geneva the main place for peace talks? | Switzerland has a long-standing policy of neutrality - it doesn't take sides or get involved in conflicts of other countries. They haven't been involved in a war for over 200 years. That makes it a good place to hold international talks and make treaties, where it's in a territory that doesn't favour either side. |
Why should you buy insurance. | If it isn't required by law, then the answer depends on how much you can afford to lose. If you have enough money in the bank to buy a whole new house, then there's no point in getting fire or flood insurance. Why pay somebody else when you've already got yourself covered should something bad happen? If you can't affor... |
If taste buds are on the tongue, why can't I taste food until I chew/bite it? | Most of the spiciness in peppers are in the seeds. Until you bite down, those chemicals aren't exposed to your tongue. The outer skin of a pepper is pretty bland and flavorless. Many foods are like this. |
how come we are legally adults and we can be tried as adults if we can't still buy alcohol? | Here are just a couple of reasons. Let me just preface these reasons with this: if you do not agree, that is fine. They're the governments reasons for them. 1) Scientific studies have proven that the decision making part of the teenage brain is not developed yet. 2) A lot of mothers decided that teenagers were dying to... |
Why do they serve Wings with Celery Sticks? | It's mostly just tradition. There is something to be said for having a crispy, cool, bright little calorie-light snack in between wings, but it's not some sort of magical pairing with reason or rhyme to it. It's just tradition. |
How come Asian countries that were relived from European colonial rule have been somewhat better off than Africa ones? | Much of Asia was an advanced civilization to begin with, having a strong understanding of mathematics, written word, and architecture. When these nations became colonized, this didn't change. Slavery was achieved by hiring tribes to capture rivals. Much of Africa has been tribally divided and deeply entrenched in super... |
Why is the back of my tongue a greyish yellow color? | Because it's buildup. It looks gross because you probably don't typically brush back there. Try brushing back there more often and it'll clear up. :) |
Why aren't [can't] TV manufactures make 4K 3D TVs? | From my bosses mouth for us to tell customers-\r\rThe resolution is so high and clear that a decent 3d picture requires too much money and processing power. That's why all 4k tvs will come with passive 3d but not active. Also, 3d is on its last legs anyway. 4k gives you precise and realistic detail without the need for... |
Why are cable boxes so big, yet more technologically advanced devices such as smart phones can fit in the palm of our hands? | All of the below: 1. The cable boxes you are using are not New products, they are fairly old. a Newly made cable box could be small. 2. Cable boxes are technically Leased to households, with 36+month ROI to the provider 3. There's not much incentive to invest in R & D for anyone in the industry 4. Nobody is canceling c... |
Why do countries which aren't even at war, spend billions upon billions of dollars every year to fund the military | When ~~we~~ the United States entered WW1, ~~we~~ the United States was terribly unprepared. ~~We~~ The United States Army didn't even have helmets and had to borrow some from the British. For most of it's history, the United States didn't have much of an army. Most of what ~~we~~ it did have spent most of it's time fi... |
Why restaurants have policies to throw out food at the end of the day instead of donating/eating it? | Where I work, we are happy to donate our leftover food, but for us at least, the responsibility lies with the place we are donating them to. It's up to them to pick up the food, but sometimes they are very inconsistent in when they pick it up, and we don't like having days old food now taking up space in our store. |
Why hasn't Bill Cosby been arrested? | All they have to go on is testimonies. No DNA evidence or security footage. It's mostly he said she said. You really can't arrest someone without evidence. |
Why is it legal that I can google an US citizen and find out he or she was arrested for something? | Because if the state can bring secret charges against people, it can lead to widespread abuse of that power, causing the government to subjugate part of the citizenry it deems undesirable or politically inconvenient. I am very glad to hear that Germany doesn't have problems like that. |
Is it theoretically possible that our vitamin D production from the sun is a small, minuscule step in evolution towards wider nutrition gains via some process that resembles photosynthesis? | I don't think the case could be made. Plants turn energy from visible light into stored energy in the form of carbohydrates. AKA photosynthesis. Humans on the other hand do not get energy from the sun. UVB rays bump into molecules of cholesterol, irradiating them, and turning them into vitamin D. Very different process... |
Why do athletes make significantly more money than people like the president who have greater responsibilities in society? | Not all athletes and sportspeople are paid a lot. I remember reading earlier this year about some Olympic Athletes that were barely paid minimum wage; yet they were training for longer than what a full time job would take up. I suppose; that the very high paid athletes and sportsmen and women that you hear off and that... |
How do they make sex scenes in movies? | yep, they're covered up and not actually having sex. it's why you won't see a vagina, becuase there's a sheet between them. and anytime you see boobs but not a face, that's a body double. |
What in the world is going on at the end of 2001 A space odyssey | Dave reaches the Monolith in orbit around Jupiter. The monolith opens a wormhole and he travels very far very fast and sees some weird stuff. At the end of it, he arrives in a room. That's weird, I thought he was just in space. Is he alone here? Who built the room? Wait, who's that over there? Also Dave, but now he's o... |
Why is the Windows Explorer so bad in calculating time? | I'm guessing you copied thousands of files with a few large files in between, and not 1 large one. From what I can tell it assume a zero latency file creation rate, when really it's significantly slow. It would appear to the software that a 500 byte file took a relaively vast amount of time to finish, thus a slow estim... |
Why is the American flag backwards on the uniforms of Military personnel? | It's not backwards it's blowing in the wind as the soldier moves forward towards combat and kicking ass.The British flag is also flipped the other way tooThe field of stars always leads in the direction of travel. As if the flag is streaming behind. On Greyhound buses for example, the flag decal on the Driver side is "... |
why do people naturally dislike the taste of some food? | I think that taste is more of a learned behaviour than a natural one. People's tastes change throughout their lives. Anecdotal: I used to hate tomatoes as a child, not I'll eat them with no problem. |
Since people pay for a college class, why are there attendance requirements? Why can't you pay for the class and show up for just the tests to get a grade? | Don't know about US. But in my country it is because if students were given a choice only a handful of them would actually show up at morning classes. Imagine if you're 40 years old with tonnes of research work that you would rather be doing than lecturing only to find out 5 out of 100 20yo students actually bothered t... |
What happens if you give out your social security number? | Well, it's one more bit of information that can be used to identify you and access your data. For instance, whenever I call up my internet provider, they ask me to identify myself with the last 4 digits of my SSN. Someone without that information would find it harder to impersonate me. |
Why do companies expect people to give 2 weeks notice before quitting but won't give 2 weeks notice before firing or laying people off? | I think the concern is that people who have been told they are being fired don't make the best workers. Some companies actually escort people out when they give notice, for the same reason, but others don't, since many workers are motivated to want to leave on good terms.My notice period has always been mutual / same e... |
Russian bombers probing US defenses | With those aircraft yes, there is a 100% interception rate. Russia doesn't have the stealth technology that the U.S. air force has that we know of. And even then, those planes can still be tracked. They're just flexing their muscles, telling us, if we really wanted to, we could reach you. They don't really mean anythin... |
Why does the period table end at atomic number 103? Why can't there be elements with higher atomic numbers? | It doesn't end at element 103 , currently it ends at [118] , although with the way the table is set up if element 119 is found it'll slot right in under francium. The bigger the nucleus gets the more unstable it gets. Elements higher than lead generally aren't terribly stable and undergo radioactive decay down to more ... |
Why do birds move their heads around to look, in quick 'jerking' motions, and not smoothly like human and animals? | Nobody's mentioned [saccades] yet, but humans are also incapable of moving their eyes smoothly. Try it. Unless you are tracking an object that is already moving smoothly, your eyes will jerk from point to point as well. The difference, as some others *have* pointed out, is that most birds can't move their eyes independ... |
Did the dinosaurus really go extinct because of a meteor? | > It just seems to clicheish What do you mean by this? Is it a cliche for extinctions to be caused by meteor strikes? I can't think of many times this has happened that we know of, other than the one. It is theoretically very possible, and there is a lot of evidence to suggest that something like that happened around t... |
Why am I miserable when the temperatur rises 10º, but I can take a hot shower for 10 minutes and it feels great the entire time? | ~~Because in the shower, the water can still carry away the extra heat from your body, despite being hot itself.~~ ~~But in the air, the water needs to evaporate in order to take heat away from your body, which it can't do very quickly if it is humid.~~ See lizzyshoe's and maxmidget's comments below. |
Why do pharmaceutical companies air commercials for prescription drugs when laypeople can't actually directly buy these products? | Patient: I need that drug I saw on TV, I think it will really help me. Doctor: Sorry ma'am, that drug won't help, it's for something else entirely. Patient: But I saw it on TV. I'm positive it will help. Doctor: I'm certain it won't. You're fine without it, you just need a better diet and more exercise. Patient: Well, ... |
- Why I was blond till I was 5, but now have dark brown hair, and why my beard is dark brown while short, but turns redish as it grows longer | I was also extremely blonde as a kid but have since turned to brown hair around the same age you described so I'm also curious. As far as your beard I would guess that it gets highlighted by the sun the same way hair does. The longer you grow your beard, the longer it's exposed to sun, the lighter it gets.I have no ans... |
How come countries in the northern hemisphere seem much colder than countries in the southern hemisphere at roughly the same distance from the equator? | 1. There just isn't much land past about 40^o to make a comparison to.2. Most of the land is near enough to water to have a moderating effect on temperature.3. Most of the land, especially near population centers, is at low elevation. |
why is Greenland not its own continent? | The most commonly used map drastically distorts the size of things near the poles. This is fine for having a general idea of where things are.

Why is suddenly considered modern to design websites / software in this flat style, even though it's technically less advanced? | It's like a sinusoid, common in any kind of art. First you do something simple, then you add some 'special effects' to it, then those effects become too common and don't impress anyone any more so you turn to minimalism. In some time we will become bored with this minimalistic style and invent something flashy again. B... |
Why do animals like being stroked so much more than humans? | You don't like resting your head in someone's lap and having them caress your hair?", 'I dont know for animals outside of big mammals, but cats and dogs tend to be licked by their mothers and siblings to show their affection and to get clean/healthy when babies. Our stroking probably gives the same sensation of some so... |
