Does anesthesia block the perception of pain, or just the memory of the painful experience? | I just had mine extracted a couple days ago. I believe they give you different medications. One to "put you to sleep" and the other as a nerve block. When my sedation finally wore off, I was still numb for a few hours.It depends on the specific kind of painkiller, but in general it blocks the pain signal. Your body doe... |
If the USA decided to go with full universal healthcare, what would happen to the private insurance companies? | There are a lot of models for universal health care, so it depends on how it gets implemented. For example, in the UK, the NHS covers all basic services, but plenty of people buy private insurance for increased convenience of services. Any way you cut it, private insurers are going to lose a huge number of customers an... |
If we were a computer, what would be our equivalent specifications? | Most of us would be the free calculator that you get when you open a new checking accountThere really is no way to measure it because we think in an entirely different way. On a computer it is relatively easy to measure this stuff, because *everything, everywhere* comes down to a flow of bits. With humans, it's not ent... |
How does an octopus know when its changed to the correct color of its surroundings? | There is a theory that their weirdly shaped pupils result in something called "chromatic aberration", the result of different wavelengths of light refracting at different angles. In humans this causes colored "fringes" around objects which can be observed at the edges of eyeglasses or if your eyes are dilated at an opt... |
Why does it take weeks (or months) to receive results from multiple choice exams when everything is corrected and generated by machines? | I would imagine they have tens of thousands of sheets to mark. Then keying in marks, typing out certificates, etc for some exams. I've been waiting on my UNSW ICAS results for MONTHS. |
Why do streamed movies cost the same as DVDs/Blu-Rays? | They charge that amount because people pay it. Yes, it's cheaper to stream than to produce a physical product, but since people will still pay the blu-ray prices for a streamed movie, that's what they charge.Its because people pay it for that price. If everyone stopped paying for digital copies at the same price as DVD... |
Why do we all make the same faces for x emotion? | Quite simply, because they're genetically ingrained. These expressions are not something learned, but rather are hard wired into our brain to express an emotion. |
- Why do we only ever see white people with down syndrome | Nobody is exempted from having Down Syndrome. But, there may be a variety of factors at play that have resulted in your lack of encounters with non-white people with Down Syndrome. First, according to the Centers for Disease Control, the mortality rate for black infants with Down Syndrome is higher than for white infan... |
What effects would consuming an excess amount of protein do in the long term? | According to the Wikipedia article on "protein poisoning" or rabbit starvation , excessive protein in the human body would lead to excess ammonia and urea in the bloodstream due to amino acid decomposition which leads to the blood becoming too basic. Excess urea usually gets deposited into the joints, and so one long-t... |
Who sets the start time for basketball/sports games and why do they start at random minutes? | Short answer: Because TV Longer answer: By starting 11 minutes early, in your example, the broadcast has time to start, do a little lead-in/pre-game show, if you will, and get things rolling before the actual game starts at the top of the hour. Also, it doesn't happen as much anymore with people DVR'ing everything and ... |
When i eat am I actually chewing as loud as it sounds like to me? | No, when you chew, vibrations travel through your jaw bone and directly to your inner ear, where you hear them. On the other hand, the vibrations have to travel through air to get to someone else's ear. Sound travels best in solids, followed by liquids, and worst in gasses. This is because molecules are closer together... |
How does a show like Survivor / The Amazing Race capture so many angles in a scene, especially the critical ones in the plotline? | I have an anecdotal answer for you. Several years ago, I spent a while working with a guy who won a season of the Israeli Survivor. Talking about how "real" it was, he said that all the tasks and results were legit, but that they often reenacted them shortly after they finished to allow the camera crew to get better an... |
Why can cops let you off the hook in certain situations? Wouldn't letting them do something illegal be illegal too? | He's hoping that he has scared you into learning the error of your ways. The best form of policing is *preventing* crime, and by doing things the way you described, it sounds like he's achieved his goal. You're thinking about it. "I got away with it this time - next time I might not be so lucky, so I won't do it". funn... |
Why can we walk for hours without our legs hurting but standing still for less than an hour starts to hurt | We evolved to stand as a way to walk, and everything about it is adapted to that purpose. Our balance is better when walking than standing still, circulation better, everything about it revolves around movement. To stand still is inefficient, joints don't work as well because they're not being regulated by a rhythm, we... |
Why do I gag when I put a finger down my throat but food doesn't have the same effect? | Because when you swallow, peristalsis is pushing the food down that way and your brain recognises that. Also, you tend not to hold food right at the back of your throat with your throat open. If breathing through your mouth, your tongue tends to hold the food away from the back of your throat anyway so you don't inhale... |
How do animals know who won a fight for dominance? | The victory for dominance comes when the an animal has established dominance over the other. Whenever the other animal feels powerless to continue, the dominating animal will psychologically feel being "in charge". The other animal might feel "under control", and thus he/she isn't dominative. How an animal "knows" who ... |
How do surfers speed up to escape a crested wave? | It's mostly unweighting off the bottom of the wave, the "flats", and hopping the board up onto the face of the wave, even ever so slightly like you see when she is near the white water. By unweighting and getting the board up, she can then redirect the board down and use both gravity and the push of the wave from behin... |
What would happen if The Moon was to blow up tomorrow? | We'd have to worry about several things: 1) the tides. The tides would be all messed up, and we certainly would see changes in the way our seas and oceans behave. 2) We'd have to worry, possibly, about pieces of the moon falling on us. |
When we launch space missions, what's stopping other nations from believing that's a targeted bomb or nuke and how is it different from an actual attack? | First of all, its not like a space agency fires up this massive and amazingly complex rocket with complete secrecey, and goes "surprise! Its STS-134. You know, delivering supplies to the ISS. Yeah, usually we plan these things but we had a spare shuttle stack lying around and a few astronauts were looking for something... |
Why do you get hungrier after we snack on something? | When you are really hungry for a while, your brain realizes that you're not going to feed yourself, so it shuts down the thingy that makes you feel hungry, after eating something small your brain realizes that you are feeding it and since you need the food it turns the thingy that makes you feel hungry back on |
why a manual transmission vehicle can sometimes stalls from a hill start | Manual transmissions work by manually selecting a gear and then supplying the engine with the right amount of gas to get a 3,000+ lb car going as you engage the gear. Normally, you're on a flat surface so the amount of gas required is that which generates enough energy/momentum to "push" the weight of the car forward. ... |
Why do Americans dye their cheese orange? | What color is cheddar cheese where you come from? All cheese is naturally white, or off white, or even a golden yellow, depending on the type of milk used. But you'll never find a cow that gives orange milk. The color instead comes from the flavorless Annatto seed, which gives Wisconsin cheddar that pumpkin orange hue.... |
What makes Unreal Engine 4 so... unreal? | In simplest terms, no other game engine has the sheer amount of man hours poured into it as Unreal Engine. UE has had a ton of resources available to hone their craft. Keep in mind this is the 4th iteration Unreal Engine 1 came out in 1998. [Here's a pretty comparison of versions 1 through 3]", 'So you ask why the Unre... |
Why do we hear our own chewing loudly when we close our ears? | Normally you're hearing the sounds from outside your head, that go into your ears. But, you also hear a lot of sounds from inside your head, that are less from the vibration of the air but the vibration of your actual body/head. This is actually why your voice sounds different recorded than it does when you speak - bec... |
Why don't we trigger our gag reflex when we swallow food, but we do if we put our finger down our throat? | Our body doesn't like something being both down our throat and out of our mouth at the same time as it will choke you. Same goes for toothbrushes. You mouth is very aware of the size and shape of things you shove it it. |
How does the "bidding website" scam work? | Those web site you see ads for that say PS3 just sold for $2.56. Well it did "sell" for that but the trick is that you must pay for each bid you enter like $1.And they will keep changing the end time of the auction so more people will pay that dollar to enter a bid. Technically it did sell for that, but that was after ... |
Why when you pour water into a pot with hot oil it reacts like that? | Oil floats on water, so the water gets under the oil, quickly boils, and the escaping steam blasts little droplets of oil all over the placeWater immediately falls to the bottom of the pot/pan, underneath the oil. Because the pan/pot is presumably at a high heat, it vaporizes very quickly into steam. Since the water is... |
How do meteorologists report what the temperature “feels” like | How the temperature "feels" actually matters. The feel is actually a better measure of how much heat loss/gain your body is experiencing than the actual ambient air temperature. For instance, say it is 1F today, and the Wind Chill makes it feel like -10F. As your body radiates heat, a buffer of warmer air forms around ... |
EL5: Honestly, what the fuck could happen if my iPad stays on when the plane lands? (I'll check this in 15 minutes when I'm on the ground) | Nothing electronic-wise. Its so you 1)Will pay attention if there is an emergency and not be listening or music or distracted. 2)In case there is a hard landing they don't want those things flying around the cabin . Off is so you won't be tempted to grab it anyways.The issue with electronics on a plane isn't so much "w... |
If I pay off my visa with a mastercard within my 21-day grace period, assuming the mastercard had said grace period as well, could I not just shuffle a debt indefinitely? | What you're describing is called a balance transfer. Most credit cards only give you the 21-day grace period for making purchases. You have to pay interest immediately on cash advances and balance transfers. TL;DR - probably not. You'd have to pay interest on your MasterCard from the day you use it to pay off your Visa... |
Why do I feel like shit after a nap? | You wake up in the middle of a sleep cycle. When you sleep, your body is reorganizing your brain. Waking up in the middle of a sleep cycle is like waking up when your body has pulled everything off the shelves but hasn't started putting it back yet. I started using _URL_0_ and it made a HUGE difference.I was always the... |
How is it possible that I can completely forget how to do something that I've done hundreds of times, even immediately after successfully doing it once? | I have discussed this with my Psych professor a few times. Our brains are still a deep mystery. I can give an example of myself struggling with this. I have put in my passcode for my dropbox hundreds of times. Then one day I forgot. I did not have the faintest idea what my code was. I didn't forget for a day or week. I... |
How does mopping clean the floor, if the soapy water just stays on the ground? | you will typically mop in back and forth passes. The mop will get the floor wet which will help dissolve dirt on the floor. A second pass will catch the dirt. You repeat multiple times until the floor looks clean. You then put the mop in the bucket to get fresh water and release the trapped dirt. You do not necessarily... |
Why does the scent of petrol, cellotape, glue, correction fluid and a few other objects that aren't used for their scent appeal to people? | A lot of those chemicals contain some amount of benzene. Benzene-like compounds are referred to as "aromatic". They have a fairly strong and often pleasant or sweet odor.I find the smell of gasoline and diesel appealing. Pretty much any fluid for a vehicle other than coolant I like. I assume it's because I am a gearhea... |
How does a speedometer work? | Speedometers work by linking a flexible cable to the car's transmission. As the engine powers the drive shaft, it spins the cable about it's central axis ? The cable then spins a magnet near the speedometer. The speedometer has a metal needle and a spring that pushes the needle towards 0 mph. As the magnet spins faster... |
How hard is it to change your name? | In the UK, it's similar to what RabbaJabba says about the US. Here, we call it "changing your name by deed poll". You obviously need to prove who you are, and there are rules about what you can change your name to. The really don't care why, although you do have to affirm that you aren't trying to get out of something ... |
why are certain products designed so differently in different markets? | Some of it is market preferences, which may simply have been set way back when products were first introduced decades ago. Could also do with things like what surfaces get cleaned most — Americans have more carpeting on floors while I think European homes use vacuums on hard floors, drapes, etc. Trucks are a combinatio... |
Why Intel and AMD don't make smartphone CPUs? | Because they were making a lot of money off of desktop and server CPUs. And smartphone CPUs need to be fundamentally different from desktop CPUs because they need to be very power efficient. Thus they would effectively have to start from scratch to create a mobile CPU or try to make their x86 CPUs more power efficient.... |
How Stephen Hawking has managed to survive with ALS for so long? | It is common knowledge that Stephen Hawking died long ago. His chair achieved sentience at some point, critics disagree on when, and is currently posing as the scientist.> Don't people usually die much sooner? Usually, but he got the [early and slow version]. Most ALS patients don't live past five years or so after dia... |
Why Google might possibly not go national with fiber when internet is an industry in desperate need of disruption. | They don't have to offer fiber in every single market to disrupt the ISP ecosystem. All they have to do, and all they're trying to do, is embarrass the ISPs into making progress. Google doesn't really want to be everyone's ISP because that's not their core business. |
Where did the idea that classical music makes infants smarter come from, and has it been proven? | There was a study that showed pretty well that listening to music made adults temporarily better at doing a spatial reasoning paper folding task. This sort of melted into "classical music only specifically makes people smart" to "classical music makes babies smart". It's some pretty big leaps from the original study. |
If elephants are being slaughtered for their tusks, why don't reseves remove them without injuring the elephant so the poachers have nothing to slaughter for? | Quite often, poachers don't kill the elephant first-just cripple or sedate as necessary. Removing the tusk is a severe enough injury that the elephant will die from blood loss soon after, while in debilitating pain for the remainder of their life. Keep in mind, they go deep into the elephant's face, often a foot or mor... |
the U.S. fiscal cliff approaching and why it's coming? | This was asked a couple hours ago and got a pretty good response I thought. I'll link it _URL_0_ |
What has atmospheric pressure to do with wind speeds and the wind force? More Info In Text | Atmospheric pressure is basically the weight of the column of air sitting on top of you, so it's directly linked to the atmosphere's density. Wind speeds are just, well speeds, it's an important factor but in physics, we know kinetic energy is directly proportional to the object's mass. Mars' surface pressure is only 0... |
What happens if you move a nocturnal animal from one end of the world to the other? | No, it would be active at night. In the same way that we adapt to time changes when we travel so would theyWe moved our cat with us across time zones and he adjusted to the new day/night schedule just like we did. |
Why is the Swiss National Bank saying it will buy all other currencies in unlimited quantities? ELI5 | The Swiss Franc is actually too strong verses other currencies right now. This sounds like it would be a good thing and too a degree it is but Switzerland relies on exports as a major part of its economy and if no one can afford your exports then you have problems so they wanted to cap the value of the Franc verses the... |
Why is the Middle East perpetually in conflict? | * Muslims have multiple sects and some of the members want the others dead. * Israel and Palestine both feel they have divine claim to the same portion if land. Neither side has a point of compromise and many would rather die than lose.* The US and Russia have enormous monetary interests in the area and use these count... |
why does turning on your wifi on your phone, even if not connected to a wifi, help pinpoint your location. | In the background the phone is scanning for which wifi hotspots it can see around you. Given this information your phone can ask Google/Apple/etc over your mobile data connection where hotspots with these particular names are located, these companies will have large databases of such information and can tell you roughl... |
Why can it be really bright inside and I can see my phone screen just fine but when I'm outside it becomes hard to see? | It's because the surroundings are really bright, your pupil contracts. This helps you see the surroundings. But your phone can't match the brightness. This makes your phone appear darker. |
Why do we get white marks on our fingernails? | Your nails are actually layers bind together. When something hits your nail the layers separate and the trauma spot will become opaque. The only way diet could affect it is when you don't get enough nutrient and your nail becomes weak and more prone to damage. |
When birds fly, do they know where they're going every time or do they just land wherever? | I live near a long string of parks. Over decades I have watcher the behavior of Canadian geese in particular. Groups will do to the golf course or another pond on a regular schedule. They fly a direct route between these locations. They definitely know where they are going. I remember one terribly windy winter day when... |
Where does the term 'ninja' come from if in Japanese it's 'sasuke'? And is ninjutsu something different in Japanese? Sasukejutsu? | Are you talking about the show Ninja Warrior? That show was called Sasuke. Ninja is a Japanese word, as is the alternate reading, Shinobi. The word literally stems from the character "endure." There's arguments that there was never really a historical ninjutsu, as a distinct art, but that most of the ninja aesthetic co... |
Why is the 1-2-3 on the top row of a phone keypad but on the bottom row of a calculator? | the first phones with an actual keypad used it to match the old rotary phones, which had the lowest number first. calculators existed before that, and had already established the 7-8-9 on the top row', "Numberphile did a video on this: _URL_0_ Tldw; The 3x3 grid style was settled on because it was the easiest to make. ... |
Why is the search for "intelligent life" so widely talked about and seems to be a prominent goal for NASA? | First of all, you're correct. Finding any life would be a big fucking deal. However, that's actually not very likely to happen. What's much more likely is that we will find evidence of alien technology, such as radio signals or something else that travels at light speed. Remember, any evidence that we find will have to... |
Why do we use White and Black to describe race when the skin tone is actually Beige and Brown? | Color vocabulary has evolved and expanded throughout time. I highly doubt the word \'beige\' was around when this usage was solidified. We do this all time time when it comes to naming binary pairs, in order to easily distinguish them, even when the designations don't match up perfectly. Think about white pepper. It's... |
Why do TV shows do the fake lines on the screens to make it look like a home recorder, when today they look the same quality? | To convey to the audience that the scene is taken with a recorder, in universe. They do a lot of shorthand like that. The "shink" sound of a knife being picked up. Dial tones on cell phones. People typing on computers and the individual letters appear on their face. It's not realistic but serves the story. |
We are one consciousness experiencing itself subjectively | Here's a short story that I think gets the idea across very effectively: _URL_0_ There might be more 'philosophical' ideas about it out there, but this introduces one idea about it in a very understandable way; with this context, it might be easier to understand the more complex ideas. |
Why the smoke curling off the tip of the cigarette is blue, but when you smoke the color of smoke is white? | It has to do with the lungs adding water vapor / stuff to the smoke which affects its Rayleigh scattering. Walter Lewin has a nice demonstration/explanation of this in one of his MIT lectures. [_URL_0_]. . |
How anxiety and stress cause physical symptoms (Specifically tinnitus, dizziness, headaches, numbness) | Stress causes your blood pressure to rise and this causes the headache and numbness. Higher blood pressure also makes it easier for your blood to transfer oxygen therefore increasing your stamina. This helps if you are being chased by a lion but is bad for your health if you are always stressed out. Check with your doc... |
when my phone is fully charged it tells me to unplug it to save electricity. Is it actually more efficient to run it off the battery? | power is being converted by the transformer even when it is plugged in and being converted to heat, so yes sort of.A phone uses an infinitesimal amount of electricity when charging. Let's do the math. 1 amp X 5 volts = 5 watts 5 hours a night = 5 watt hours. 365 days per year = ~2 kilowatt hours. In NYC right now, the ... |
Do twins get concieved from the same singular sperm that reaches the egg first? | There are two types of twins, identical and non-identical . Identical twins form when a single sperm fertilises a single egg, but somewhere, early in foetal development it splits in two and both continue developing into children, resulting in two children with identical DNA. Fraternal twins form when two different sper... |
Why do newly released blockbuster films only circulate on the internet when they have been released on DVD? | First of all, cinemas don't get their movies on DVDs . They used to get movies on movie reels back in the days of analog film. These days cinemas receive a Digital Cinema Package, or [DCP], which is basically a computer hard drive in a special enclosure which contains the movie. So, as long as a movie is still only in ... |
Why do guys insist on sending unsolicited dick pictures. Does that ever REALLY work? | Men are very visual creatures, and quick to arouse. A man can go from no arousal to immediately turned on just with a quick flash of a girl's boobs. As a result of this nature, many men don't grasp that women don't work the same way, and aren't interested much in seeing a dick unless already aroused. Combine that with ... |
Why don't phones just capture video in horizontal mode no matter which way you hold it? | The actual sensor in the phone that captures the image is itself also rectangular - in the same direction as the phone screen. To make the phone record video in horizontal mode when it is held vertically would result in using a lower resolution, as it would require ignoring a large portion of the sensor . To continue t... |
why storing 256mb of data in the 70s require a massive machine, compared to a tiny USB stick now? | There's two reasons, really: the second is as a result of the first, to some extent. 1. Our ability to manipulate minute things has improved, as has our capability to mass produce fiddly little things. 2. We've developed different things to store the data in/on. Back in the day electronic data storage was limited to ta... |
What happens if I bring a plant with a seasonal lifecycle indoors? Will it skip its dormancy or die out of confusion? | That depends. Plants are numerous and very diverse. The easiest example I can think of is the Venus Fly Trap. The biggest mistake short of not giving them full sun is that people bring them indoors to keep them warm over the winter. These plants require a cold, relatively dark winter dormancy or they will die of stress... |
Why don't submarines have cameras mounted on the outside to aid in the use of sonar? | It gets dark underwater really quickly. Without a visible light source, you probably wouldn't see more than a few feet, which is vastly less than what sonar can give you. And that's assuming you got clear water, which usually isn't the case. |
Why does my room not stink to me, but when my mom walks in she thinks it's horrible. | Animals rely on scent as a sense to understand their surroundings. Take a poodle, give it a perfumed bath, and it'll still sniff that fire hydrant given a chance. Take a retriever, have it roll in a carcass that it uncovered somewhere, and it'll still be able to whiff out a concealed hot dog. Our mammalian brains have ... |
Why does your jaw drop when you are amazed or horrified? | Does it actually do that for most people? I've always just thought that was a cartoonish way to show those reactions so it would be clear. |
why should the ex-partner of a marriage get half of their ex-partner's business when they divorce | You have to look at these things from the perspective of the "whole family". One spouse might be working day and night to build a business and generate a lot of money for the family. But in doing that, they're NOT looking after the house or the kids or the dog, they're not cooking or cleaning or setting up the house fo... |
Why do our noses run when we're outside in the winter? | In the winter, it's important that air becomes warm and humid before entering your windpipe and lungs. Cold, dry air would harm the delicate tissues there. One of your nose's jobs is to help make air more suitable for breathing. The snot your nose is producing helps moisten the air you're inhaling. It actually has fun-... |
Why is it obvious when someone deliberately avoids looking at you? | There are very few people who can exude a natural demeanor when they are actually forcing it. Basically, they are trying to physically fake what they think they look like when they aren't paying attention to a specific stimuli. It's easy to spot because people aren't good at this and it's apparent in their face, body, ... |
Knot, as a unit of speed | If you represent the earth as a circle containing 360 degrees, a nautical mile would be one minute of a degree. A knot is one nautical mile per hour, or one minute of a degree per hour. Very usefulA knot is a nautical mile per hour. A nautical mile is 6000 feet, so a knot is slightly faster than 1 MPH. |
Why does intense hunger sometimes cause nausea? That seems like the opposite of what should happen. | Because your body is trying to encourage you to eat! Here are the two possibilities I've read about: According to when you eat, your body will release a hormone called Ghrelin which makes you feel like you're starving, possibly to the point of feeling nauseated. So if you normally eat every four hours and you missed a ... |
Why do most SUV's, Hatchbacks, Station wagons, Vans all have rear window wipers, but almost ALL sedans, never do. | I think I know the answer to this one! The near-vertical boxy non-aerodynamic shape on the rear of SUVs vans etc tends to cause dirt from the road to end up on the glass, sedans don't suffer from this effect as much. |
What does the "Night Shift" feature on an iPhone actually do? What are it's benefits? | it basically reduces the amount of blue light that's displayed by the display when the ambient lighting is low. blue light can interrupt sleep patterns and is generally bad for your eyes in low light. |
why is the reverse side of a coin called "tails" ? | Typically the other side has someone's head on it, so the opposite of "heads" being "tails" is rather fittingBecause "Head or Ass?" is a question for a different situation. |
Why do we find organs and other insides of the body so revolting? | I would have to say that it's just a natural response. Those things are supposed to stay inside and when they come out your brain just automatically knows something isn't right.Because it's all one giant blob you see, and then realize that that stuff is inside you too! If you are over your initial shock and take things... |
How do you train a dog to do complicated tasks like grab something from the fridge? | Operant conditioning. Basically, dog does something vaguely relating to the task and gets rewarded. Teaching a dog to open the fridge would start with the dog being rewarded for approaching the fridge upon command. Them rewards would subside and they would be encouraged to interact with whatever handle is given to them... |
Why does attraction cloud judgement? | You have a reproductive instinct that drives you to breed. It is outranked only by basic survival - the hierarchy of needs Genetically, reproduction is your one and only purpose beyond survival, and even the quality of your attempt is secondary to any mating at all. The reproductive drive also doesn't need any rational... |
What causes the rhythmic beating of helicopter blades in motion? | Vortexes! A wing moving through the air creates high pressure below it and low pressure above it. At the tip of the wing, the high-pressure air from below spills sideways and swirls around to the top of the wing, creating a [wingtip vortex]. The rotors of a helicopter are just like the wings of a plane, so they have wi... |
Why is being fat less attractive? | I read somewhere once that attraction has a lot to do with a primal/subconscious desire to pick a mate based on chance of success for offspring. Like a woman would want a muscular man because her children could be strong. So maybe more obese people would be unlikely to out run danger and therefore not a good choice as ... |
How does wrinkle-free clothing work? | Fabric wrinkles because the chemical bonds that hold it in place are broken by heat and water. When they dry and cool the bonds reform and they get stuck in the new shape. Different materials are more or less susceptible to this. Polyester for example is not so bad. But it not so nice to wear. For example: Water breaks... |
Why dont other countries have military bases in the US, While the US has bases in many other countries? | The US has a huge military force with the primary mission of projecting force worldwide. Most other countries have comparatively small forces with a mission of only local self defense or regional force projection. Local self defense obviously does not require bases half the world away. Many countries also depend on the... |
How do pictures get from the hubble telescope back to earth? | Pictures are taken by instruments, digitized, and sent to Earth by radio. It's sent to a Tracking and Data Relay Satellite, from there to White Sands New Mexico, via ground optical fiber to Goddard Space Flight Center in Greenbelt Maryland, and finally to the Space Telescope Science Institute in Baltimore. About 125GB/... |
How did the word sanction come to have two completely different meanings: 1. to approve something and then 2. A threatened penalty? | It comes from the root sānctiō, meaning "a law or decree that is sacred or inviolable." The **verb** sanction still essentially means the same thing for the positive or negative - to 'sanction\' something is to give it official approval. So technically the **noun** also means the same thing - a rule or decree that has ... |
Why is it that mirrors flip images horizontally (i.e. Left to right) but not vertically (up and down)? | They flip front to back, up remains on your up, and your left remains on your left. You just see a face in the mirror and assume that you must have rotated, since you have an arm on your left and an arm on your right, you assume that they were swapped since that's the only way people can do that in real life. You don't... |
Why does inhaling helium from a balloon make your voice sound high pitched like a cartoon character? | Helium is 6x less dense than oxygen, so the sound waves travel through them faster and you sound like a cartoon character speaking quickly. Fun Fact: Sulfur Hexafluoride is 6x more dense so it'll make your voice sound slower. |
Why do I suddenly shake when I have to pee really bad? | When your bladder starts to fill the pressure sensing nerves present on its outer walls send a signal to your brain alerting you that you need to pee. The pressure sensing nerves send this signal before your bladder is completely full to prevent damage. When you ignore that signal, your bladder continues to fill. You s... |
Why does most graffiti look similar? | It looks similar to you because you haven't learned how to distinguish styles or quality. If you had, you'd be able to pick out good from bad. |
When scientific papers refer to the mass/size of the Mt. Everest (to compare), what numbers are they actually taking? | This is why *real* scientific papers use actual numbers and actual units, not "as heavy as a fully loaded 747" or your example. There is no official answer. They're winging itWhen you get to huge numbers like that, size comparisons are usually a pretty rough estimate. So it doesn't especially matter whether they mean j... |
what would the Catholic Church do if Jesus came back? | Probably flip a shit, when he turns out to be brown.They'd probably ask him to perform a miracle or two to prove it |
Where does award money on game shows come from? | The TV company producing the show.

I'm 27/m. How can girls on "The Bachelor" be ok with dating a guy who's making out with 20 other girls and in fantasy suite when there's 3 girls? | Most of them aren't. That's pretty much the entire plot line of the show. Jealously, cat fights, and falling in love for the "right reasons." The show has it all--except reality, basicallyYou'll come to realize that the term "reality show" is only half correct. They are shows that have almost no basis on reality. Heck,... |
Who authorises drone strikes and ground missions on foreign ground? | The person that authorizes it is different for each military. It is the person that is in charge of the military.

How are popular animated TV-shows made these days? Who draws all the frames? | Some are still produced in the West, usually with computer technology as a major enabler using tecniques like keyframing .

Hat happens to water/food when it falls in the lungs? | A small amount of water will usually be okay provided it wasn't contaminated with bacteria. The tissues basically just absorb it. Food almost invariably results in something called aspiration pneumonia, basically it makes your lungs really sick from bacterial growth, and because of that your entire body responds as wel... |
How does vacuum insulation (like in a Thermos) work? Why is it so good at keeping things hot or cold? | Heat travels in three ways, convection, conduction, and radiation. Convection is from an air or fluid flowing over the object. Example: the steam coming off tea, or when you open a hot oven and feel a blast of heat on your face. Conduction is from the two objects physically touching each other to transfer heat. Example... |
