how can animated shows, like the simpsons, be cranked out episode after episode so fast? | They're all being worked on simultaneously. This way, every episode is in the same stage of production at the same time which greatly cuts down the amount of chaos and time spent in total. How do you think shows that are Netflix originals can release all the episodes at once? It's kind of the same thing but on TV, they... |
Why is there such a huge gender gap among Wikipedia editors? | I had no idea this was true. It suggests a problematic bias in Wikipedia.> Why is there a huge gender gap in < profession/interest/field/ > ? Because people of different genders have different interests, goals, capabilities, desires, etc. As long as everyone has equal opportunity to do whatever they want, there's nothi... |
We have 4G on phones and tablets that allows us to access the internet anywhere, so why can't we have the same for laptops? | You can. You can get 4g dongles for them. You have to sign up to a data plan for it and away you go. Presumably they are not usually built into laptops because most people use laptops where WiFi is available. |
What is happening inside the brain during lucid dreaming? | Dreaming is kind of like an altered state of consciousness. You're still conscious, but you're dreaming, and there's different areas of the brain that are activated and other parts that are shut down. Being drunk is a good example: when you're drunk you fall a few levels down the consciousness scale, physiologically an... |
Why Don't I Have Nightmares Anymore? | More recent research shows that dreams and nightmares are a playground for your mind to play out scenarios so you can "learn" to react.

How is it possible for Cam Newton to pay a 198.8% tax rate, as claimed by Forbes? | He's not paying all of those taxes on his Super Bowl winnings. He's paying taxes on his normal salary too. And his normal salary is about $20 million a year, so even a small fraction of that is more than what winning the Super Bowl pays. The article's point is that, if he *weren't* playing in the Super Bowl in Californ... |
why are gas prices going down so quickly? | They always do this time of year Colder weather climates require a different fuel octane ratio or a car wouldn't be able to start. The increase in regular gas lowers the demand and therefore the price. |
Climate change, how is the earth warming, and making some parts colder at the same time? | Climate change can, among other things, alter prevailing trends in global wind currents. For instance, some studies in Europe have suggested that the loss of sea ice could contribute to a phenomenon where artic air currents predominate more steadfastly over Northern Europe than they do now. So even though the Earth as ... |
How come the British colonization of Ireland was able to spread the English language but not religion? | It did spread religion. England was originally Catholic, and they spread that Catholicism to Ireland. Then, during the rule of Henry the 8th, England split from the Catholic church, so that Henry could get divorced and remarried. That's how you get the Church of England. |
why does a coke machine sometimes give me 2 cans instead of one? | It's just a basic cost-risk trade-off. A more accurate machine costs more money than a less accurate machine. Soda is cheap, so giving one out for free every once in a while is less costly than buying the expensive machine. That being said, If you are regularly getting 20 cokes from the machine it is likely in a state ... |
How do UV lamps dry nail polish? | There are groups of materials that react in a specific way to certain circumstances. Sometimes it's water, sometimes it's air, sometimes its light etc.It's mostly related to the way the material is built, internal structure, how particles are arranged and connected. In this case, there is a substance called photoinitia... |
Why if our body temperature is 98.6* do we sweat and feel hot if it is 90* outside? | There are lots of chemical reactions going on inside your body at any given time, and most of them generate heat. In fact, since your body is thick and solid , and made mostly of water , you generate enough heat raise your body temperature above 98.6 easily. Much like a computer, you need a heat sink to keep yourself f... |
do vegetables, or meats take longer to digest, and why? | Digestion is the process of breaking up food into a form that can be absorbed by your body. There are 3 major groups that we distinguish in the type of the food we digest. Sugars, proteins and fats. Both meats and vegetables can contain all 3 of them and depending on the type of the meat or vegetable in different amoun... |
The difference between 4WD HI and 4WD LO. | 4 Low is a lower gear set, for when you need more power. You're using a gear set that moves more pulling power to the tires, in exchange for extremely limited speed. 4 high is a higher gear set, for when you want power to all 4 tires, but don't want to be as limited in your speed. It's the 4WD equivalent of first and s... |
If there isn't such thing as a sugar high, then what causes you to act hyper after eating candy or drinking a can of coke? | [Peer pressure and placebo, mostly.] Similar experiment involving non-alcoholic beer produced "tipsy" people even though the drinks contained absolutely no alcohol. Look at people who drink vitamin water/fruit juices which contain almost as much sugar yet don't act hyper since they believe they aren't drinking sugar.We... |
Why do computers, as they get older, slow down even if there are no viruses/spyware on them? | Computers don't get slower. Badly written OSs get slower. This is particularly a problem with Windows OSs but it is not confined to them. Its just more prevalent in them because of the architecture of the constantly updated shared libraries and registry. There are a couple of things that slow down windows machines over... |
Why do movie studios disclose everything about their movies' budgets and revenue but game studios don't do the same for their games? | Movie studios generally don't disclose everything about their budgets. The stuff you see is just a publicly releasable number regarding an approximation of the production cost of the movie. Thats just one aspect of the overall process, and its a fundamental part of the movie processes, so its often a pretty well known ... |
How does Hand Sanitizer work, and how effective is it? | The active ingredient in most hand sanitizers is is isopropyl alcohol, which works by disrupting the lipid structure in cell membranes. It's also quite effective against common viruses since they are usually enveloped in a phospholipid shell as well. It's [quite effective] with some caveats. |
Why do phones need SIM cards? Do they actually allow connection or are they just data storages? | Well 'need' is a strong word. Technically they don't need one, and they can make a 911/999/112 call just fine without one if they're in range of a tower. Your carrier requires it because it's a means of authentication. It's reasonably secure for use as an identification. The SIM is how the network knows your phone from... |
why planets rotate on a flat plain? | The solar system was developed from a cloud of gas. That cloud of gas condensed and started to spin for whatever reason The condensing and spinning flattened out the cloud. The center became the sun, and the remainder of the cloud that wasn't taken into the sun became the 8 major planets of the solar system, all in the... |

The most common are basal cell carcinomas that don't often invade to become malignant. But can come back. There are also genetic factors and past history factors that can make them more likely to recur or having genetic traits that can make ... |
Why are electric cars and hybrids, which have more powerful motors, quieter than power drills and blenders? | The power tools and such might be using brushed motors which are notoriously louder than the brushless design I would imagine a serious car would useThey have space for more sound dampening. Your car is quieter than a lawn mower for similar reasons. |
Why do classic arcade machines have players look at the screen through a mirror rather than looking directly at the monitor? | Those monitors were HUGE. If they had put them facing you, the back of the machine would have poked out really far, so they put them in the bottom, reversed the image , aimed them up and have you look at the reflection. Basically, they did it to save space. |
How come prisoners in supermax prisons where they're not allowed to talk to anybody don't all go crazy? | They do. It's a real issue, solitary confinement causes massive mental trauma on those inflicted by it. |
Why do accents exist, and how did they develop | Going back hundreds of years a lot of people would never go more than a few miles from home. Communities tended to keep to themselves. So throw in a language to two communities that are a distance apart, fast forward the clock through decades and centuries, wouldn't it be even stranger if - after all that time - the tw... |
Why does putting salt on a slug kill it? | > I'm comfortable with the idea of diffusion . This is the key to understanding osmosis, along with the idea that **water is no exception to this rule**. The salt ions will try to move from one side of the slug's skin to the other until they're evenly distributed but they can't, because the slug's skin doesn't allow sa... |
Why do stars twinkle if the light we're seeing is from thousands of years ago and most things aren't big enough to block its light? | Stars twinkle due to atmospheric interference. If you 've ever seen "heat waves" shimmering above a road, you're seeing a similar principle at work. Gasses can cause interference with light passing through them. In the case of a twinkling star, you're seeing the atmosphere scattering the light as it passes through.Just... |
how the website Kickstarter works and how it helps people who want to use it. | ok, if someone has is a good idea, but no money to fund creation or production of said idea. what they usually do is to find investors, people that will give you money to fund your project in return for a slice of your profits. what kickstarter lets you do is to get funding directly from the people who want your servic... |
Why do companies trap the back button? How can making it very difficult to get off a page be good for their site? | without running such a site, I assume that these overtly obtrusive sites are only in it to make a dime once. They dont expect you to return but they will get as many page loads as they can while you are there.One way would be to load a Web page after their home. So you go to _URL_1_ and it takes you to _URL_0_ you hit ... |
How it is made that cars speedometer's arrow shows the car's speed at crash moment? | This isn't something speedometers do. Many cars now though do have black boxes that record the speed at moment of impact. It can do this because its a computer that records data as it happens and then can sense a crash via sensors. |
Our cell phones update our pictures and contacts to the cloud, why can't a planes black box do the same? | Because it lost contact. The point of the black box is to store information *after* the plane loses contact. All of the pertinent information prior to losing contact is already transmitted.Black boxes only record a certain amount of data before the over write existing data. About 4 hrs of recent data at all times. But ... |
Public vs. Private Citizenship in America | If you're talking about the sovereign citizen types, who claim that you aren't bound by tax or other laws, there **isn't** a way to do it, and trying it will get you fined or sent to jail when you break one of those laws they supposedly aren't bound by. It's a scam, pure and simple. Up here in Canada, they call themsel... |
Why do humans think other sentient beings would use radio signals to communicate with other intelligent life? | Most of scientists who are looking for other species, accept that other species might use other methods of communication but since WE don't have access to those methods, radio is our best option. The scientists looking for radio waves aren't expecting all other life to use radio waves but they are hoping that if we stu... |
What happens to our social media accounts when we die? | I can't speak for the others, but Facebook actually has a feature where you can have your account 'memorialized' or permanently deactivated in the event of death. With a memorialized account you can link another account, friend, relative, whatever, and they're given some control of your account; they can't read your me... |
Why doesn't taxidermied animals rot like other dead animals? | A) Because the gut is removed, which contains the bacteria that cause the body to rot in the first place and B) because the skin is embalmed to prevent it from rotting. |
The drug levothyroxine for Hypothyroidism. | Levothyroxine increases your overall metabolic rate and thus, helps your body manage fat better. It shouldn't have any effect on muscle gain, assuming you eat enough to ensure your body doesn't start metabolizing protein/muscle for energy. Having greater than normal amount of thyroxine in the body can have several bad ... |
How do phones like the Nokia Lumia charge wirelessly? | This is called '[Inductive Charging]'. What happens is that the charging station uses electricity creates a vibrating magnetic field. In the phone , this vibrating magnetic field causes a electricity to flow within a coil. That electricity charges the batteries. The principle is is to use some process which allows for ... |
Why aren't shampoos and soap used interchangeably, and how do those shampoo-body all-in-one soap work? | IIRC shampoos and soaps have different levels of hardness. You CAN use regular soap on your hair, but it'll treat your hair more harshly than shampoo. |
Why aren't more electronics waterproof? | It is significant extra expense and engineering challenge for something most users don't need. Most of your life is in a dry environment, why spend a lot of work so you can dunk your laptop in the tub?", 'Because it can cost a lot. Most electronics needs to be opened up to put new batteries in, for repair, or ease of m... |
why is it more instinctual to hold our breaths while lifting something heavy, than it is to breath properly? | when lifting an heavy object, your body needs to become rigid enough to lift such object. So you start tensing your muscles to create a strong enough structure capable to lift. Breathing involve the diaphragm to expand and retract the rib cage. in order to do so, the upper chest needs to be "soft" enough to allow the c... |
Why does it seem like all of Africa is politically unstable? | Many African countries are quite stable, but there are a lot of African countries so the number of unstable ones in Africa can seem high. Much of Africa was also under colonial rule at some point until this century; as a result their borders got drawn somewhat arbitrarily, artificially dividing and grouping cultures an... |
What happens--physiologically-speaking--when someone returning to riding a bicycle builds up immunity(?) to being saddle-sore? | A few things. Just like you form calluses on your toes, heals, hands, etc. Your tissue also toughens in response to the added stress targeted in that area. Your sensory also becomes a bit dulled as use goes on just like you get used to wearing glasses for example.Mostly what's happening is in your legs. Early in the ye... |
Facebook application request limit reached | Welp, i was just directed here after a search, glad to know, this is more of a widespread issue. Hoping it'll get fixed |
Why does a broken mirror show many tiny images instead of one image with lots of cracks? | The glass is all pointing in slightly different directions, and so the light reflected off of each little surface is coming from a different place before being reflected to your eye. |
What would happen if a nuke were to explode in space (not low atmosphere)? | Let's assume we're dealing with an early Cold War ICBM for our nuke. The explosion would go off just fine. It wouldn't resemble a mushroom cloud, though. That has to do with gravity and air currents. It would look relatively spherical. Anything in the immediate blast radius would be damaged quite a bit, less than you m... |
The Abramovic Method. (Specifically, as used in the new Lady Gaga Video) | It's Performance Art. It doesn't sound like there's anything even *remotely* scientific about it; rather just her personal views on how to be 'more aware of your surroundings'. |
Why Do Cars "Squat" | Because by applying torque to the drive shaft, differential, and then the rear wheels. There is a secondary reaction in the car's rear springs. They are "winding up", or "loading up". So for example, if you had stiffer competition springs, you 'd notice less squat. On a front wheel drive car, this whole scenario takes ... |
Why can't I start my own nation? | It becomes recognized whenever other countries recognize it. That's not a satisfying answer, but it's the truth. Just ask Palestine. There are only two things stopping you from finding an island and starting the People's Democratic Free Opensource Republic of Doge: finding an unclaimed island or convincing a country to... |
Why is such an emphasis placed on only a couple states during the U.S. presidential elections? | The "swing states". Most states are typically majority conservative or liberal. It's a waste of resources to go campaigning there. The majority party wins all of the electoral votes. But certain states are very close to 50/50 splits. These ones are worth a focus because a few points swing in voting makes a huge differe... |
What is chloride in a hydration IV and why do you need it to be hydrated instead of just water, sodium, potassium, etc? | Simple answer is to maintain your blood's PH and isotonic balances. IV fluids are usually sodium chloride solution, .9 & #37;, which is the level that you would find in human blood. WIthout the right balance, water would be an irritant and change the electrolyte levels in your body, causing potential problems with elec... |
Why is it that we can consume substantially more liquid by weight than we can food? | Liquid is absorbed faster. Water fastest of all as it needs 0 digestion. Solid foods start chemical reactions and your body notices it and has to work before it can be advanced to the intestinesMy understanding is that liquids leave the stomach within minutes, while solids take a few hours to break down enough to move ... |
How did US voters figure out which presidential candidate was the best in the early days of America? | Mostly, they didn't, that's why the electoral college is a thing. In Theory, you'd vote for the most intelligent/well informed guy from your county, and then he would go vote for the candidate he thought was best. In practice, you voted for the delegate from your political party, and he would vote for whomever the part... |
What is going on with the top post on /r/wallstreetbets? What will the stream be about? | There are two ways to invest in stocks and shares - normally you buy them, and if the company makes a profit they give you a dividend, and you can sell the share if the compnay value goes up. You can also 'short' a stock - that is bet that a share's value will go down. You do this by borrowing some shares, selling them... |
if the cabin of a commercial airplane is pressurized why do I have to "pop" my ears while ascending and descending | Because the cabin is not pressurised to the equivalent of surface level. It is pressurised to the equivalent of around 8000' - significantly different pressure to the surface, but not so low as to be dangerous. As you climb or descend, the pressure inside the cabin gradually changes between surface pressure and 8000'. |
How do movies & music albums get leaked? | Many times it is leaked by either a store who sells the CD's or by early reviewers. The stores will always receive their copies before the release date so at any point it's in the inventory, it's subject to leaking. |
Is face blindness restricted to humans or is this something that's been observed in other species? Is it understood what causes it? | Not many animals rely primarily on sight to recognize others, and fewer still rely primarily on facial features. I would imagine if it happens in animals, it is pretty uncommon and restricted to our closest animal relativesIt's due to a problem with a particular brain region, the fusiform gyrus, whether as the result o... |
The process of dry cleaning. | Check out the [_URL_0_] if you want to know more specifics but here is a TL;DR for the lazy. The process is basically the same, the only difference is dry cleaning doesn’t use soap and water as the medium for dissolving dirt. It instead uses another liquid that is equally as adept as dissolving oil and dirt. Usually a ... |
How do digital cameras know when an object is in focus? | You can tell if an image is in focus by looking for sharp edges. Out of focus objects that look blurry will not have sharp edges. The camera looks for sharp edges by scanning through the photo pixels and comparing each pixel to its neighbours. If a pixel is very different to its neighbours it is an 'edge'. The auto-foc... |
The origin of "your mom" jokes. | according to recent archaeological finds, it seems to be from ancient Babylonian philosophy or writing students, about 3500 years ago. a tablet had a list of riddles, most condescending or conceptually funny at the time, such as: The deflowered girl did not become pregnant. The undeflowered girl became pregnant. What i... |
If salt water is left alone does it separate into Na+ and Cl- ions? | Yes they do. Most salts, including NaCl, naturally dissociate into cations and anions in water. Looks like this: _URL_0_ |
What's so hard about taking CO2 out of the air and putting it in the ground? | You know how you get energy when you burn carbon? Well, if you want to split CO2 into carbon and oxygen, you have to put that energy back. Plants get this energy from the Sun. [Methods for replicating this process artificially] are still an active area of research, not economical for widespread use yetI think if you ju... |
Why does every RV/Winnebago you see seem to be made by a different company? Is there like no consolidation in that sector? | What you're seeing on the side of the RV is the "brand" not the manufacturer. There are probably 20-ish big manufacturers that make 80% of the brands you see on the road. Each manufacturer usually specializes in a particular "class" of RV, for instance Fleetwood makes almost exclusively Class A motor homes while Skylin... |
Why do some vegetarians eat fish? | They're not vegetarians, but because the term "pescatarian" isn't familiar to most people, they find it easier to describe themselves as vegetarians who eat fish. The obvious followup question is why do they eat fish if they're against eating animals. Part of the answer is that some vegetarians aren't against eating an... |
When burning a CD, does a 4x vs a 1x write speed change the quality of the end product? Is there anything different about a 4x vs any other speed other than, speed? | I always thought this harkened back to the old days of CD burning, where buffer underruns occurred frequently. A buffer was created for the data being burned, and if the buffer emptied before the burning process is complete, it would fail. Burning at a slower speed meant you didn't empty the buffer and cause problems. ... |
How do copyright laws work? How heavily are they enforced? | Copyright law is the idea that when people make creative content, they and they alone can decide who profits from it for a limited time. Generally, this means that if you want to use content from something with copyright, ask first or be prepared for a lawsuit. However, there is something called Fair Use in the United ... |
Is there a reason we ejaculate in spurts rather than a continuous stream like peeing? | So imagine you have a turkey baster. You have a certain amount of fluid in there that you want to get out. If you squeeze it gently, you'll get a dribbling stream. It doesn't go very far and a bunch is still left inside. Now take that same turkey baster, and squeeze it hard. The fluid shoots out and goes further, right... |
When does a date become a girl/boyfriend? | Probably when the individuals involved start calling each other boyfriend/girlfriend. I don't think there's a solid definition beyond that.When you stop dating other people and stop looking for others to dateThis is determined largely cultural. Generally people become a couple if they agree on itWhen you spend time wit... |
Why do people have different kinds of laughter? | Lots of factors. Some of them are physical - people have different pitched voices, different body sizes and differently-shaped insides, and that changes the way anything that comes out of their mouths sounds. And some of it is psychological. Some people, perhaps through shyness or social convention or just a habit of k... |
Lysenko's approach to agriculture, Lysenkoism | Lysenkoism is the byword for bringing politics into science. Marxism-Leninism claims that any competition between individuals is a result of an unjust society with private property. If you allow a revolution to overthrow the bourgeoisie, and build a society of advanced socialism, you will produce the utopia of communis... |
In extremely obese (~1,000lbs) individuals, why does fat tend to collect in uneven pockets, particularly favoring one area or another, instead of being more evenly distributed throughout the body? | It may be because there hasn't really been any natural selection or sexual selection among humans regarding fat distribution. Being able to become obese at all has historically been rare enough that humans haven't evolved to favour fat being distributed symmetrically or evenly, so fat distribution is still very varied ... |
How Does an Oven Cook Food Enough to Eat if It's Off for 2 Hours? | Beef is a relatively "clean" meat. Because it's so dense, all the nasties tend to live in the outer layer, which of course cooks first. And an oven heated to 350 will maintain a good temp for quite some time so It's a combination. I certainly wouldn't do the same thing with chicken or pork because they both need to be ... |
Why don't you feel the same way listening to a song like you do the first time after you've listened to it too many times? | Just natural human reward center mechanics. Think about it like this. If I gave you a million dollars tomorrow you would feel great. Possibly the greatest day of your life. If I came back a week later with another million that would feel great too. But what if I came back the next week? And the next week. And the next ... |
what Flat Earth Theory is, and why believers are called crazy | It's pretty self explanatory. Flat-Earthers believe that the earth is flat, that if you start walking in any direction, you will eventually fall off the edge. It's crazy because the evidence to the contrary is so convincing that no scientist has seriously considered it for over 2500 years. |
Why poison frogs don't poison themselves | Time for a little cellular biology. So quick rule of thumb, a lot of what makes up biology is the shape of molecules. The reason why certain things act a certain way in biology is usually because a particular molecule is shaped in a useful way. So toxins have their own shape. Likewise, the proteins they affect have the... |
What are the benefits to the United States in constructing the Keystone XL Pipeline? | As a Canadian who works in the Oil Sands I have to say I strongly oppose the Keystone XL. The political message in Canada is that it will create jobs. In reality, our high paying refining jobs will move to the states, where the weather is more favourable, the standards more lax, and the lower wages make it more afforda... |
How are fingerprints formed? | You have 3 layers of skin - the epidermis, dermis, subcutis. Now the epidermis and dermis have to mesh together like a jigsaw puzzle - this is called interdigitation. This is done because you can't have your epidermis and your dermis sliding over each other as you touch stuff. Your body is a very well evolved piece of ... |
how do sports commentators know all the players and their backgrounds so readily? I realize they are fed the info beforehand but they seem to spit out the info at appropriate times and so easily. | They typically have notes on hand during the broadcast, additionally they have a producer in the truck feeding them information60 minutes did a feature on Chris Collinsworth a couple years ago. He does not just show up and announce the game. He spent over 60 hours a week preparing for the game he was going to call by w... |
how do you determine the 'pack years' of a smoker? | 1 pack = 20 cigs So 10 cigs per day x 20 years = 1/2 pack x 20 yrs = 10 pack yearsIf you smoke after the age of thirty, you are going to have a bad time.One pack year is one packet of cigarettes per day for a year. So 2 pack years could be 2 packs a day for 1 year or 1/2 a pack per day for 4 years. As Plavix75 said, a ... |
How can a 500mg pill be the same size as a 10mg pill? | The pills aren't 500mg, the dose of the drug is. Some drugs need to be buffered differently so they will be absorbed by your body properly without causing a reaction. That could very well make a 10mg dose require a bigger pill than a 500 mg dose of a different drug. |
I have allergies. Why do I get sneezing fits every time I get out of the shower? | I'm no doctor, but it may be because the humidity in your shower loosens the particulates in your nose which causes a reaction.Personal anec-data, but with medical support: I was having ridiculous sneezing fits every morning with tons of excess mucus production and assumed I just had allergies. Went to the doc for test... |
The current European economic mess. | The European Union is a collection of states that are integrated at a level never before seen in human history. Part of that integration is a shared currency and many other economic ties. Several of the European Union States are experiencing an aging population, which combined with very generous social benefits have co... |
Why are Japanese game titles often just strings of arbitrary words? | These are titles that were released in Japan with the title in English, so there is a bit lost in translation as they are trying to make their titles work with the way the game is. Here is the reasoning behind the titles in your example: *Bravely Default* is an RPG where you have a "special ability" to either be "Brave... |
Why are passwords said to be safer if I use uppercase, lowercase, numbers and symbols? | The longer the password, the more potential passwords a hacker or cracking program would have to try before guessing yours. Using more randomized passwords, increases the odds that it won't land on yours. It depends on the program and goal. I have lists of passwords for different penetration testing that I am doing. Fo... |
How does my mobile phone know when there's an incoming call? | Your phone constantly pings or sends information to cell towers for information. Cell towers route the call to you so when your phone says, "hey, do I have anything?" The Tower responds by giving your phone the call or a text message or just the time. |
Why is it that when it's a really cold night outside, the sky is so much clearer & crisper to see the stars more clearly? [Serious] | The sky isn't clear because it's cold, it's cold because the sky is clear. Clouds act like a blanket that keep the warmth radiating from the earth's surface escaping into the upper atmosphere so easily. Without the clouds, the heat escapes. This is why deserts are usually freezing cold at night - no moisture for clouds... |
Why does our voice sound different in a recording than what we hear ? | When you talk, you hear your voice both through vibrations in the air , as well as through vibrations in the bones of your skull . A recording accurately recreates the part that everyone else hears When you speak the sound vibrations reach your internal ears partly through your body. You hear yourself partly internally... |
Why do airplane staff have to open/close the windows at set parts of the flight? | I actually asked a flight attendant this. She told me that it is a safety thing. They want people to be able to see if there are any hazards outside the plane. Also, keep in mind that a plane has no rear view mirrors. It is literally impossible for a pilot to see their wings. If some thing was wrong the only way they c... |
Who do bruises turn blue? | As you may know, your body contains a lot of small pipelines carrying blood to everywhere in your body. What happens if you bruise, is that one of these pipelines or veins burst and spill blood. Now you may wonder: Why is that stain blue, while blood is red? It has everything to do with how we see colors. If white ligh... |
What is the difference between using < tables > or < div > in webpage layout? | Web development has moved towards more semantic markup. In a super small nutshell its kind of like the idea of using the right tool for the job. A table is *supposed* to be for tabular data, not layout -- this is why it is generally not used for layout anymore. It doesn't make semantic sense to. In other words, if you ... |
why do email clients on android require access to calls and calls details? | The only explanation I could think of is so the app knows the phone is in use, and it won't attempt to transmit or recieve and fail unnecessarily. As for call logs idk. But it could all be for marketing purposes as well.If you tap a phone number in your email, it will send the number to your phone app. So it needs acce... |

Why aren't there any fruit-bearing plants that grow underwater? | Fruit is there for the plant to spread its seeds through fruit eaters' feces. In water, the seeds would float away once pooped out, so cut out the middle man and go straight to floating away. Submarine fruits aren't evolutionary beneficial.Most under water "plants" are actually algae, which never got around to using se... |
Why does the Japanese language use so many English words, even in cases when you know they must have an equivalent word in their language? | While Japan does have inherently Japanese words, what they're translating is a franchise name, not a word. Trying to be faithful to the original name does have its advantages: firstly it shows some respect for the country's culture and secondly it increases cultural diffusion, and thus, globalisation. Japan, as you mig... |
Why are male nipples fine to show, but females are taboo? | It depends on the culture. You're assuming a Western focus. It's much less taboo in Europe, and even less so in other parts of the world. There's no real good answer beyond that. Culture doesn't really have to "make sense". A lot of it goes back to when showing any type of skin was considered immodest. Gradually that s... |
Why is the divorce rate so high in the US? | Who says it's high? It's high*er than it used to be* because nowadays we advocate divorce when relationships are abusive, dysfunctional, or unhappy. In the past, you were expected to stay married even they beat you, if they were a junkie, if they molested your kids, if you just weren't in love anymore and wanted to mov... |
Who invented the internet and how is it owned by nobody? | The inventors of the internet are Robert Kahn and Vint Cerf. Internet is not a single thing. It is a set of thousands of other things. No one owns it. A nice analogy would be agriculture. No one owns agriculture, agriculture is a set of techniques. The parts of the internet are owned by various people and companies tho... |
Why do companies wait till the Super Bowl to make good commercials? | I suppose the best time to invest a lot of money into the production of an ad is when it is guaranteed to be seen by many, and be talked about later on. And in order to have the ad stand out in front of the others, so that the investment in the spot was worthwhile, it has to be very good. It's an ad competition. |
When we crave certain foods, is it because our body knows we need it? | My brother is a pediatrician and says the same thing. Some caveats though: sugar and fat is so scarce in nature that we are hardwired to want it when it is available - which is not good in today's society. My brother does also refer to a theory that one of the reasons we have so many nutritional issues today is because... |
