Why do computers/programs freeze/crash? | It means theyre working. when you get to the theoretical side of computer science, it's actually impossible to tell when something is in an infinite loop, or just taking a very long time. Generally, the computer has just come across a large amount of data it must go through, or may perhaps be waiting on a callback from... |
How much of the music does a songwriter actually write? | It is sort of complicated. Generally, the person credited as the "writer" comes up with the main composition, or chord structure and melody for the song. For instance- Sting is listed as the sole composer for "Every Breath You Take", because he came up with the chord structure- but when you think about that song, it is... |
Why do we use implants for breast enlargement instead of something biological like stomache fat? | Fat is a living tissue. Transplants of living tissue are more expensive and have higher risk of complications. Implants are biologically inert and relatively easy to implantThis actually is a thing, but you have to use large amounts of fat as not all of it "takes" and has arguably more complication potential than impla... |
Why does the svartifoss waterfall cliff have squares | It looks like [basalt pillars] erroded from the bottom. Basalt, due to the crystalline structure or something like that, naturally forms these shapes.According to the paragraph under the picture, they are hexagons, but I agree they look square. Anyway, if you use Ameoba's idea of the natural basalt crystals, plus that ... |
How to catch up/develop a well informed opinion on world news and politics? | Personally, I like Christian Science Monitor and The Economist. The BBC is also good for factual stories on world events.Not sure this is exactly the right subreddit to ask this question, but I would advise the most important thing is to read from a *variety* of sources. There are a number of places I personally get my... |
The political structure of Bosnia and Herzegovina | Bosnia and Herzegovina consists of two "entities", Republika Srpska and the Federation of Bosnia and Herzegovina. The borders between these two are more or less defined by the territory the opposing forces of the Bosnian war held. The two entities are mostly autonomous, but they are both represented internationally by ... |
The ItWorks! business model. | [This article] suggests that, as you might expect, it's very hard to get anywhere near the income advertised. |
Tomatoes and peppers are native to the Americas. Why are they identified with traditional Italian/Indian/Chinese/etc food? | A handful of centuries is an extremely long time. I wouldn't be surprised if the foods you mention almost completely supplanted traditional foods in Asia and Europe. Many New World crops offered vastly superior yields and nutritional value -- the introduction of potatoes to northern Europe caused an increase in availab... |
Why are nike shoes $150 or more and how do they enhance performance in sports? | It's a fashion statement mostly. Don't get me wrong - there's some technology and research there, but not nearly enough to really affect, well, anything that much. You may jump a few millimeters higher through some new bouncy sole and lighter material. And there is some stability enhancements that will slightly reduce ... |
How all these big websites lately have been getting their data hacked. | Properly securing websites is one of those things where if you're doing your job right, no one notices. If you're doing it wrong, no one notices until you get compromised. This is why it often doesn't get enough attention. In addition, because various sites are architected in many different ways in terms of software an... |
why is depression so common in our species when the ultimate goal is to pass genes on? Isn't that counterproductive? | Humans, because of the society we have made for ourselves, don't necessarily need to respond to environmental pressures genetically when it comes to passing on our genes. A person with clinical depression in our society can be treated and still have sex. It's not preventing genes from being passed on, and that's the qu... |
The "Economic gap" between the "1%" and the "99%" | This is obviously a very complicated question, ~~Nobel Prize winning~~ economist Thomas Piketty set out to explore it in his book Capital. What it comes down to is this: If you make enough money to keep you alive, you will never get any richer. Every day you will earn $5 and at the end of the day you will have $0 left,... |
What would happen if you were quiet for years? | The vocal folds are mucous membranes. Unlike muscles, which can atrophy and deteriorate from lack of use, using or not using the vocal cords doesn't really make a huge difference in their well-being. You might have some voice breaking or stammering when you try to speak again after a long time, but it's not like they w... |
Can imaginary numbers be represented visually? | One very helpful concept that helped me understand complex numbers is [this]. It makes a lot more sense when you think about it in the way described above. Real numbers lie on a real number line, going forward for positive numbers and going backward for negative numbers. But imaginary numbers force you to deviate off t... |
How do news outlets get a hold of all those secret tapes and documents that they reveal exclusively? | These usually come from whistleblowers or people who leak the info. Some news organizations pay for stuff, like TMZ or the National Enquirer. Most media companies don't pay . Usually sources give this stuff freely for a couple of reasons: - They want to expose corruption.- They have an ax to grind against a person or o... |
The difference between race versus ethnicity. | Simplistically and quite generally, race is what most people think of as one's physical form, and is based on outward appearance. Ethnicity is what most people think of as one's background, and is based on things like language, clothing, religious customs, etc. There are no hard lines between these designations, some o... |
Why do we get so much satisfaction out of popping things? | It's actually pretty simple. When we get surprised or something happens suddenly, our brains send blood and endorphins through our body. Popping something provides us with a "controlled" surprise where we know we are going to be surprised and we also know that we wont be harmed. So we get the benefits of being surprise... |
How do grown up (no longer in school) "bullies" work? | Well, its probably not a good idea to think of "bullies" like they are a separate population with their own tactics and strategy. Most people that we would consider bullies are just regular people like you or me, and I can guarantee that we 've all acted like bullies a time or two ourselves. Have you ever been rude to ... |
Why do we, and all other animals, breath and use oxygen when nitrogen is so much more available in the atmosphere? | The nitrogen gas molecule is extremely stable and hard to crack apart. Most living organisms can't do it - most of the biological nitrogen in existence came from specialized bacteria. On the other hand, the oxygen gas molecule is highly reactive, meaning its energy can be harnessed for useful chemical reactions, like t... |
What is it about potatoes that makes them go so well with so many different foods? | Potatoes are have a relatively neutral flavor. This means they can take on the flavors of other foods without greatly disrupting the flavor profile. They're also cheap way to add bulk and calories to a meal. Recall that calories are only a bad thing in societies and ages of affluence. In times and places where food is ... |
How are police sketch artists able to draw people relatively accurately based on descriptions? | It's something of an open question whether they are all that accurate. Often they are accurate only in the gross details and aren't otherwise recognisable. It's quite rare for a suspect to be identified purely on the basis of an accurate sketch, though. |
Why do most song lengths seem to fall between 2 and 4 minutes? | Much of the answer has to do with the length limitations of vinyl 7" 45 rpm singles, which for many years were the primary means of promoting a single song. You can only fit about 3 minutes of music onto a 45 rpm single. So historically, if you wanted to write a hit pop song, you had to keep it under that length. More ... |
Why is Kim Davis being held in contempt of court instead of just being fired for insubordination? | tl;dr: Elected officials cannot be fired - they must resign or they must be removed from office through impeachment proceedings. Kim Davis is an elected official. So she cannot be "fired." There are two ways that she can be removed from office - by impeachment and by resignation. In the same way, President Obama cannot... |
What is that falling feeling you get in your stomach when you go down a hill in a car or rollercoaster | Did you ever jump into a cool swimming pool or river or something, and notice after five minutes or so that it's no longer cold? That's because your body 'gets used' to things after a bit. Your body is used to gravity . So you don't even notice that your insides and the content of your insides, are all under one gee of... |
Why is the sea made out of salt water? | Almost all natural water contains salts and other minerals including rivers and sweet water lakes just in different levels. Rivers flow constantly so the salt they pick up from the ground does not have time to build up to the point where it tastes salty. But oceans and lakes get all of this salt poured into them by the... |
What do investment bankers actually do? Goldman Sachs, etc. | treedick is speaking about regular banks that give loans..not investment bank. Let's take Goldman Sachs' Investment Banking division Basically, they underwrite securities. Facebook is going public, they go to an investment bank to help them raise capital. Investment banks are financial intermediaries. |
What is bad about universities like the University of Phoenix and DeVry? | They admit anyone who has the money to pay them, regardless of whether they are ready or able to do the coursework. They provide subpar education at excessive cost. Their graduates tend to find themselves not particularly employable, and in a lot of debt. |
How do wireless speakers work? | Just like radio. There is a transmitter and a reciever. In the case of Bluetooth, the transmitter is something like a smartphone. Then the speaker recieves the signal, and amplifies it. |
Why does touching the contacts on a 9-volt battery not shock you, but something like putting your finger in an electrical outlet will? | here ya' go: _URL_1_ While potential is 9v, the current is very low. The batteries ability to shock is negligible. As is 120v given low current. However most home circuits are breakered to 15 or 20 amps. More than enough to kill a person who sticks a fork or tongue in an outlet. As for the difference in voltage vs curr... |
how do people deep fry ice cream? Wouldn't it melt? | First of all the ice cream for this is frozen at extremely cold temps, then it is quickly battered and fried, so while the ice cream softens up a little .it is still plenty cold.It's not the ice cream that's fried. It's coated in batter, basically a thin layer of donut around the whole thing. The dough is fried and ins... |
On what grounds can a gaming company sue an individual for creating gameplay hacks? (Aimbots, etc?) | When you pay for software, you're not actually buying it- you're buying a *license* for the right to use the copy that you have. This may seem like a minor difference, but legally this allows the owner of the software to determine *how* you're allowed to use it. The details of licensing are found in the EULA, which mos... |
Why does my nose get runny when I eat/drink something hot. | Spicy foods irritate the mucus membranes in your head and lungs. Your body reacts to this by making you create mucus, to coat and protect you from whatever may be causing the irritation. You also tear to protect your eyes, which drains into your nose, exacerbating your snot nose. You can also sweat because your body th... |
Someone dies before they get a chance to retire. What happens to all of their social security benefits? | US Social Security works less like a piggy bank, and more like a Ponzi Scheme . Unlike most pension plans, citizens do not have individual "Social security accounts" which they pay into while they're working, and later withdraw from when they're retired. Instead, every currently working citizen pays into one big pool, ... |
Is Magneto (from X-Men) good or bad? | Think of Magneto as ideologies. X-Men has always been a metaphor for people who are different, marginalized, etc. Thinking back to the Civil Rights struggles of the 1960's , you had people advocating non-violent protest and you had people who were, well, not necessarily violent, but definitely more militant . Both had ... |
Why does Bayern Munchen/Munich have the 2 names, and which one is "correct"? | Its official German name is "Fußball-Club Bayern, München e.V.", normally abbreviated to "FC Bayern München" or just "Bayern München". "München" is the name of the city -- its German name. To English-speaking people, the city is better known as "Munich", so in English-speaking countries the club is known as "Bayern Mun... |
Where do TV ratings come from? | The main ratings firm is the Nielsen Company. Hence the term Nielsen ratings. This works basically the same way a political poll works. There are statistical methods for looking at the way a small number of people answer a question and figuring out how the population as a whole would answer it. Just like they don't hav... |
The controversy surrounding the 2000 election (George W. Bush vs Al Gore) | It was an extremely close race, the deciding state being Florida. 537 more Floridians voted for Bush than for Gore, but across the board, in the entire country, Gore got more of the popular vote. So the supreme court made the decision that since Bush won Florida, the deciding state, by a margin of 537 votes, that Bush ... |
What's the difference between a flash drive and external hard drive? | An external hard disk is called as such because it utilizes a Hard Disk Drive . One of these drives has a metal platter with different magnetic sections, called sectors, that are read by a small magnetic sensor called a head on the end of an actuator arm. Many people are now moving over to flash storage, however, which... |
Why are colleges and universities so different from each other (Yale vs a local community college) but all of the information taught in school is the same for their respected fields ? | I studied physics at a reasonably high-ranked school, and I can tell you definitively that 90% of what I learned that actually stuck was from working with other students, not from lectures. The caliber of fellow students is hugely important in my opinion, and you simply get better students at better schools. I also con... |
How do various worms dig into people, and how do we not feel it? | they normally enter through food when they are very very small. alternately there are some parasites who can enter through cuts that already exist in the skin. |
why are transgender issues suddenly all over the place? | Causes are fashion for many people. And transgender issues are currently the most fashionable. I say this as someone who fully believes that trans people deserve equality and freedom from persecution, but also as someone who recognises that people clearly bandwagon. |
How can clams grow shells? | In a very similar manner to how humans grow bones and teeth. They capture the elements they need to form them from their environment, and react them together in such a way as to deposit a solid mineral in the places they need it. |
Do News sites still see that I watched their video even if I said screw this when the Ad came up? | If the video loads even for an instant, yes - that counts as a view. It does not technically count as a complete view if you left before the video ends, however, a view in the internet world is counted as an impression. They will also know if you left before the actual video by tallying up the number of times the ad an... |
Black athletes with hyphenated names | No I meant why is it so prevalent in black athletes. I know about hyphenated names with divorced parents. I want to know why it seems to only occur in black athletes and not in other races IN SPORTSHyphenated names=parents, for whatever reason, who don't share a surname. But saying it's "black athletes" is ignorant. It... |
Why do I get a feeling someone's watching me even when I can't see them? | I've always heard that the brain records and processes every single thing your eyes see. EVERYTHING. Although it sees all, it has to choose what information it presents to your aware mind at the moment in time. Although your brain saw everything when you walked into a new room, there is only certain information that yo... |
what is "old man" strength? | Nobody's mentioned this, so I figured I'd give my $0.02. Old man strength is typically from those who have been performing some form of physical labor for a long time, and have such developed incredible grip strength. This is the part that /u/WOT_IF_UR_LEGS is talking about where it feels as if they can crush your hand... |
I've been without an internet connection since June 12th. What's going on in the world? | Most major stuff has already been covered but: *The largest Ebola outbreak ever is going on right nowFor future reference, they still print newspapers and nothing on Reddit is actually noteworthy. |
Why is a mouse more accurate than a joystick on a controller | Because with a computer mouse you move it exactly X distance on the table so the cursor moves Y distance. With a joystick, you essentially 'toggle' the cursors movement in any given direction, for a certain length of time, until the cursor reaches what you need. It's also less accurate because you're dealing with a fix... |
When was the last time in human history it would be more common to see someone walking barefoot than with shoes or sandals? | It was common up until the 1950s in the south for children to go without shoes. It is still somewhat common in regions with lots of creeks.Right now, in a whole lot of poorer places. A good friend of mine didn't have shoes until she was 16 because her family couldn't afford them.It depends on where you are in the world... |
Why do some drinks seem to pass right through you whereas plain water is retained? | The sugar and electrolytes in Gatorade and other sports drinks actually increase how much water you absorb into your blood stream. This can be perceived as too much fluid and your body will try to get rid of it if you aren't actually dehydrated. Normal water, on the other hand, lacks the sugar and electrolytes that pro... |
How does a disease make a comeback like Ebola or the Bubonic plague have recently? | Ebola has no cure, or even a real treatment. It never really went away. It's just that humans aren't commonly exposed to it , and when they are it tends to kill quickly enough that it burns itself out. So you see a series of fairly quick and nasty outbreaks in the areas in which infected bat populations come in contact... |
why are some people are more prone to insect bites? | I don't know about other bugs but mosquitoes have a preference for type O blood. CO2 also attracts them, and pregnant women exhale more CO2. Also alcohol seems to increase their attraction to you; possibly because it raises your body temperature. |
What would happen if there was absolutely no US involvement (i.e. provision of weapons, logistics, drones, etc) in the Middle East? | the IS would take over. creating a bigger "nation" that's hostile towards US relations. puts israel and our trade partners in the middle east at risk. a middle of the road country is open to trade as long as such a trade agreement does't cause problems with its neighbor. if ISIS is their neighbor, they're less open to ... |
What does the "strength" of an earthquake acutally mean? | As you may know, an earthquake occurs when two slabs of rock move relative to one another over a surface called a "fault". Moment magnitude is simply the product of the area of the fault ruptured, the relative movement across the fault, and the stiffness of the rock . It is closely related to the energy released in the... |
How does the air-pressure sensor in rotating car tires report the pressure to the stationary chassis? | There are direct and indirect systems. Direct systems have some sort of sensor in the tires that measure the air pressure, and use wireless communications to feed that data to the car's computer. Indirect systems don't measure the pressure directly, but sensors on the rest of the car measure different variables on how ... |
Where do bugs go in the winter time? | Depends on the species. 1. They hibernate - like lady bugs in the leaf litter, or female queen bumblebees in the soil. 2. They migrate south - like monarch butterflies 3. The adults die, but leave their eggs/larvae in a safe space to "hibernate" over winter and their offspring hatch/emerge in the spring - like crickets... |
or[5] Electronic Tablets/E-books. | Sounds like you should look at the [Nexus 7.] Good size for portability, amazing price and three different storage capacities , lots of free apps, and it starts at $199. There are plans for an even cheaper $100 8GB version in the future, but that is unconfirmed for now. If that's too small, maybe look at the [Nexus 10.... |
How does an electron microscope work and can it be used on living tissue? | An electron microscope works by passing electrons across the object that it's scanning. Basically, the object is coated with a heavy metal, and the electrons that bounce off get recorded, and it gets put into a computerized image that gets manually colored for effect. Electron microscopes require the object to be place... |
What's so bad about Detroit? | Poverty Jobs left the city at an ever accelerating pace over the past few years and this has led to lower and lower incomes and, consequently, higher crime and lower property values. As it gets worse fewer companies would think of moving in and bringing back jobs and the situation worsens and worsens. Their economy was... |
Why do animals eyes light up in certain colours when shone at with a torch/light? | Many especialy night active animals have a layer of reflective tissue behind the light sensing cells at the back of the eye. That allows them to caputer more light in their light sensing cells. Additionaly that makes the eyes act as a retroreflector like in the bottom image here: _URL_0_ . The color comes from the tiss... |
What causes a stye or an Internal stye? | It is usually caused by a staph infection, and can be treated by putting a warm compress on it around four times a day and just leaving it alone. Let it resolve on its own and just take painkillers, or if it is very painful seek medical care. |
How come we can land probes on comets and send satellites around the galaxy, but we can't put a high resolution color camera on these devices? | We could now. But this probe was launched 10 years ago, and was designed and built mostly during the 90s.To put it simply, more megapixels = higher resolution = larger filesize = more 1s/0s. I'm not sure about the data transfer rate between the probe and Earth, but I'm assuming that it's not a quick process. The lower ... |
Why some credit card transactions require a billing address and some only require a zipcode? | CVV codes are not mandatory, it is up to the person/company as to whether or not they want to require it or not. In some cases their Merchant provider will offer cheaper rates on transaction when CVV is used, as it leads to less fraud however some retailers choose not to do that. Many merchants still refuse to include ... |
How do gradients work in tatoos | Hi there i tattoo and its exactly how they said. The needles dont need to penetrate too deep and the more times you go over it the darker it becomes you want to go from lightest to dark. You cant take dark back. We water down the black in different amounts or whatever colors and just like water color painting we blend ... |
How did the russian revolution start? | The Russian Revolution is actually two revolutions, the February revolution and the October revolution . During World War 1, in February 1917, a bunch of workers in Russia started a strike, and basically everybody ended up joining it, including the army and eventually some key figures of the Czar's government. They for... |
How do the water intake on this nuclear plant work? And how this guy managed to go from the inlet to the outlet without a scratch? | Nuclear engineer here. He was sucked from he ocean to the intake bay. At the far end of the intake bay is where the pumps push water through the plant. The intake bay water level is at a slightly lower elevation than the ocean, which created the pressure that sucked him through. He didn't pass through any pumps or the ... |
How do the mammals of the ocean hydrate themselves. | They have awesome kidneys. The kidneys are able to filter the water to hydrate the body and remove the salt. Human kidneys are not so awesome.Their skin really locks water in well. They have physical mechanisms to desalinate water during ingestion. They get a fair amount of water from the food they eat without drinking... |
"PTSD is a cultural product" what does that mean? | If I understand this correctly, what its saying is that PTSD only exists as a recognised disorder because of the ability we have to study it. It never used to be recognised. In wars, for example, people would get it and be labelled as cowards, because it wasn't understood what the sufferers were going through. I think ... |
Why can most things in the body be transplanted, except the eyes? | Whole eyes are really tricky to transplant for a few reasons: 1. The retina dies in only 2-4 hours without a blood supply. The donor and recipient would have to be right by each other. 2. The retina is part of the brain, so if a donor is brain dead, the eye would be dead too. You have to harvest the eye right after the... |
Weird vibrating eye "trick" | it's called nystagmus. It can appear as a problem for some people, in which it is uncontrolled, but some people are able to do it voluntarily. Other than the obvious vision problems for people who have involuntary nystagmus and can't 'switch it off', I'm not aware of it being a cause of any sort of damage. |
Why are some words considered more offensive/rude than others, despite meaning a very similar or even the exact same thing? I'm referring to swear words mainly. | Similar question has been asked more than once today. It's weird. All languages have curse or swear words; words used to describe acts, ideas, or concepts that are considered taboo by the culture that uses said language. These can vary widely from culture to culture, of course, but the common taboos in western civiliza... |
Why are highway and street signs usually white text on green (at least in the US)? | You're correct that white and black would provide the greatest contrast, but the primary issue isn't contrast. Highway signs are "retroreflective," meaning that at night, when you shine your headlights on them, the light not only illuminates the sign, but the sign also directly reflects a good amount of that light back... |
Why do vehicles that carry a lot of people not require seatbelts? | I asked a school-bus driver once about this, and he replied that kids would use the seat belts as weapons. I, for one, could definitely see my teenage self smacking my seatmate with a seatbelt.I've heard that buses don't need seat belts because they'd be useless in most cases. Buses are so heavy that unless they hit a ... |
I always hear about spacetime, but what proof do we have that it exists and that all theories based on it are accurate? | There have been [a number of experiments] that have shown general relativity to be a more accurate theory of gravity than the classic Newtonian model. For example, our GPS satellites have to correct for relativistic effects. The fact that your GPS works is proof positive that general relativity is a thing. |
Only 5 White Rhinos Left (alive) Worldwide--What does that mean for the Eco-System? | Specifically, little at this time. But it is a reduction in the biodiversity that keeps the environment healthy. Best way to explain it is to simplify things - let's just hope Disney doesn't sue me. Follow the circle of life - the antelope eat the grass, the lions eat the antelope, the dead lions decay and feed the gra... |
Are product restocking fees BS or is there some legitimacy to them? | How do you define BS? It costs the business money to have employees around to put the item back into inventory, makes their logistics less efficient, etc. The entire area of return policies is a strange one. Businesses are under no obligation to accept returns for any reason. Anything they do is strictly for marketing ... |
After an earthquake, how do we tell if a building is structurally sound enough to re-enter and use again? | If there's internal damage, there will always be some amount of external damage. The amount of external damage can be very small compared to the internal damage, misleadingly so, but there will always be some. And yeah there are a lot of things you look for. Small cracks are expected in certain materials, and don't nec... |
The psychology behind game grinding | There's two - there's MMO Grinding, and there's classic JRPG Grinding. With MMO Grinding, it's a [Skinner Box]. Push button, receive reward. Early in the game you're rewarded for doing damn near anything. Talk to someone - get a level. Cast a spell, get a level. As you go up in levels, it stretches out more and more, l... |
Why do you have to get your oil changed after 3 months if you haven't driven 3,000 miles? | And you're told this by people who sell oil. Maybe that should give you a clue. Certainly in modern cars, that should be unnecessary. Edit: Spelling |
Why is it the iphone (and other smartphones) requires a separate file type for a ringtone instead of being able to use mp3's already on it? | Because that's how they are set up, ringtones are a separate purchase, so they don't want to lose money buy allowing you to natively create a ringtone from song files on your device. There are of course super simple ways to manually make them into ringtones. It's just that when you pay for the song, you are paying for ... |
Why to high performance engines like drag cars and hot rods have engines that sound like they are out of sync at an idle? | They use really big cams that do not make power until a certain high RPM, its called the power band. At low RPMs the cam isn't working efficiently. Most drag car cam's power band might be from 3000RPMs to 7000Rpms. Drag cars, right before the green light will raise their RPMS to the power band which is where the cam is... |
The difference between DVD-R and DVD+R, CD-R and CD+R? | DVD-R and DVD+R are two DVD formats. This means that the way the data is stored on the discs themselves is slightly different. From a user's perspective they both function the same and have almost the same capacity . DVD-R came first and is the "old" format. DVD+R is newer and has some advantages. For example its forma... |
How can peristaltic movements transport liquids? | Peristalsis works like this:_URL_0_ Stick a drinking straw in a cup full of water, place your thumb over the end of the straw, and lift it out of the water so that the straw is full of water but no longer in cup. Pinch the straw flat with the thumb and forefinger of your other hand up near where your thumb is covering ... |
How does the ISS maintain it's altitude without crashing into the planet? | So you know when your throw a ball it follows a curved path down back to the ground? Well the ISS is moving so fast and is so high up that it's curved path equals the curvature of the earth, so it approaches the earth just as fast the earth curves away from it, so the distance between the earth and the station remain, ... |
Why do I have to pee when I'm nervous? | You may have heard of the 'fight or flight response.' When you are stressed your body releases hormones to help your body deal with the situation - the best known one is adrenaline. This hormone tells your body to do a whole bunch of things, and urinate is among them. It is suggested that this might be to lighten your ... |
What is stopping us from just replacing our natural adult teeth with synthetic ones? | Mostly Price. Where I live it costs around £1000-£1500 for 1 dental implantWe can and occasionally do, but why surgically rip out your teeth and implant fake ones when the originals do a fine job on their own? You still have to clean and maintain the fakes, bacteria will try to colonize them both.I think you're underes... |
Since whales are mammals, and need water to live like we do, how do they get it if they live in salt water, which is bad to drink? | They get it from the food that they eat. Whales, and dolphins, can't starve to death, they die of dehydration first. They do get a little bit from sea water but their kidneys can't remove much salt so if they accidentally drink too much sea water when they eat that could kill them. |
How exactly a silent approval of criminal acts by law enforcement authorities goes through in modern, western countries? | You've kind of hit the nail on the head. It tends to vary from place to place, but I think a lot of law enforcement organisations don't see a great deal of point going after small-time drug dealers. As you say, there's always going to be demand for drugs and if any police do turn up it's pretty easy just to disappear. ... |
Why do we move our body (by either dancing or simply bouncing our head) to music? What exactly in our body is causing this? | Actions speak louder than words. Movement can encode aggression or play or healing or prayer or mating or celebration or grief. Movement attracts attention because people need to know how to interpret your intentions. Someone dancing through the front door of a bank will draw a different attention than someone dancing ... |
How are outside noises able to be incorporated into your dream? | Brains are complex things. While dreaming you are thought to be basically consolidating the memories you want to keep and not keep, and you create scenes in your mind involving things that were important to you recently . So while your brain is doing all of that, your ears, eyes, nose, and mouth are still wired in. Inc... |
How does restarting something (i.e. a computer or a PlayStation or such) work? | PC hardware comes typically with only a single program baked in, called the "bootloader".

Why are we so reluctant to kill animals nowadays when, in the past, our society used hunt all the time and feel no remorse? | People live sheltered lives, some going through all of it without killing any animals or getting into a fight. There's also social conditioning, people being told since they're toddlers that it's a heinous act to hurt people and animals. People like to elevate themselves to a moral highground by bashing the 'barbaric' ... |
how does depression change the way you think? | So I'm not quite sure why you have this labeled as chemistry, so I'm going to do my best to mention chemistry, but this is more of a biology question. You have these things called **neurotransmitters**. Some of them dictate how you feel. Serotonin is a mood stabilizer, it's very important in making sure you can have "n... |
Why, when through binoculars or a telescope 'the wrong way' do things look smaller, but you can't make the same thing happen with a magnifying glass? | There is always more than one lens/curved mirror inside the telescope, so the result is different if you reverse the order light goes through them.

Germany, from an ally became an invading force of Italy. Also, the anti-Jewish laws were repealed by the new Badoglio government while the war was still going on. Basically, by the end o... |
The Operation Teapot video is one of the craziest things I've seen. What exactly am I seeing? | > but what are the "eruptions" coming from it? Was it detonated in the air? It was detonated on the top of a tall tower. The "eruptions" are the guy-wires that stabilized the tower being boiled into gas and plasma from the light of the explosion before the blast wave proper reaches them. |
How can they clone living animals? | Well, most people use the word "clone" to mean something other than it actually is. I blame the popular sci-fi use of cloning to refer to creating an exact duplicate of a person, along with their memories and personality and such.
