Why were there so many different languages between the natives of the American west coast? | Yeah, I was thinking about Europe. That *did* happen in Europe though. There were many individual tribes and bands that unified into the basic nations we see now. [This map] shows about a dozen along the California coast alone. Also, since there aren't many prominent geographical features I couldn't see that being a se... |
Why when you oversleep, say 10+ hours, sometimes you wake up with slight headache? | Dehydration is probably he culprit. Your body is still doing it's thing during those hours of sleep and its 10 straight hours without any consumption of any fluids. Think if you went 10 waking hours without anything to drink, parched tongue, eh? If you do have the luxery of getting 10 hours or more of sleep try drinkin... |
Why has 'white cheddar' become the seemingly default flavor for any 'organic' or 'baked' version of snack food. | organic" or "non-fat/low cal" versions of snack foods lack flavor. Frying things in oil adds a lot of flavor, and that gets lost when they're baked insteadWhite cheddar sounds like more of a premium or luxurious ingredient, sort of implying that it is a smarter healther option in the process. It allows them to market a... |
How can you prove sqrt(24n+1) can give all of the prime numbers? | Write the equation: p = sqrt Square both sides and solve for n: n = / 24 So what you're really saying is that if p is prime, p^2 - 1 must be divisible by 24. p^2 - 1 can also be written as . If p is prime, both and must be even. Since they are both even, they're both divisible by 2. Since they're both consecutive even ... |
What are the consequences to an economy when people have tax havens? How do you and I have to suffer for this? | The premise of your question is partially wrong. In most cases, tax havens are entirely legal. They are simply countries with low tax rates. You're only looking at one side of the equation. If a person or business decides to put their money in a low tax jurisdiction, then the low tax country benefits. It's kind of like... |
How can 'magic mushrooms' permanently change your personality? | Okay, 5 year old Remember the first time you went to the zoo? There were all those animals you'd never seen before, and some you didn't know existed. There were ones you'd seen pictures or videos of, and ones you'd seen animated versions of, but it was a completely different experience to watch a lion prowling around r... |
How could falling foam insulation damage the Shuttle Columbia's heat shield? | I think the tank foam is heavier than pillow foam, more like house-insulation foam. But still, something traveling at 2000 miles an hour doesn't have to be heavy to do much damage. Here's an experiment: hang a light, fluffy pillow from some clips. Have a friend drive past it at 100 miles an hour with you in the passeng... |
how do big hotels keep their showers so hot and high pressured? | This is going to vary greatly based on how old the building is and where it's located in the world. Many different ways of achieving it but the most common I have seen in the US is combined boiler systems. Basically there is one boiler system that provides both heating and potable water. Some hot water goes to plumbing... |
What happens when I replay to an email that says "do not reply" | > Is there anything actually happening behind the scenes or is it so grandma doesn't think that the email is a way to reach the company and get things done? Option two. |
If I get 60Hz electricity from the wall, why don't my light bulbs flicker? | Your light bulbs do flicker. It's just that they flicker 60 times a second which is too fast for your eyes to notice. |
Why was homosexuality more accepted and widely practiced in the ancient days (e.g., Greece, etc.) | Actually, homosexuality in Greece may not have been as common as we think. In fact, some scholars believe it was only practiced with much frequency in the aristocracy. Also, organized religion was around long before the Greeks, and there may have been good reasons for not looking upon it favorably. For instance, homose... |
Why do your earbuds emit a high pitched noise whenever you walk past the detectors at a library? | The way those detectors work requires them to use electromagnetic fields . Electromagnetic fields can produce a current in materials , which is also how your speakers work- converting a current to sound. Your speakers don't have a way to tell the difference, so it makes whatever sound corresponds to that current Usuall... |
Why 2 liters of 100% pure orange juice cost ~4$ while it takes way more than 4$ worth of real oranges to get the same amount of juice? | I've worked in an apple processing plant in a previous life. The first stop is a rough sorting of apples that can be used and sold in stores, and the other nasty bruised deformed ones. Those get trucked down the road to the juicing plant. In general, the produce that gets made into juice isn't the same quality that you... |
Why are salaries at fast food places like McDonald's so low, even though they're multi-billion dollar companies? | Can they? Yes. Do they need to? No. The qualifications to be a McDonald's worker are so low that basically every person in the United States could do it. Not only that, but the amount of training required to get them up to speed is minimal. You now have a situation where if you work at Mcdonalds, every American is a po... |
Why is that near identical movies are often released at the same time (The Illusionist/Prestige, Armageddon/Deep Impact, Wyatt Earp/Tombstone, Ed TV/Truman Show) | Ideas can't be copywrited. Once the concept is floating around Hollywood, more than one version may be made. |
Why are some people against gun control? | History shows that anytime a villain wants to commit atrocities, he first makes sure that his victims are unarmed. Using the aurora colorado movie killer as an example, his weapons were used against unarmed movie goers. One would say, that if he didn't have access to guns, he couldn't have done what he did. But we've s... |
Why do special effects cost so much money? | The single largest expenditure on the cost of a shot is artist salaries - doing good-quality, complex work takes a lot of time from a large number of skilled people. A really big shot can involve a dozen or more people working for several weeks. For one shot. There are around 1500 VFX shots in your typical blockbuster,... |
How has Magic Johnson looked seemingly healthy while having HIV for the past 20 years? | HIV and AIDS are two different things. They're intrinsically linked, but different. HIV infection typically results in what's called a lysogenic infection, in which the virus writes itself into the host DNA and replicates with the host genome, without producing virions. In this state, HIV is essentially harmless; it's ... |
Why Do American's Take Halloween and Costumes So Serious? Why Is It Such An Important Event In The Year? | The answer with a lot of these questions relating to American culture is usually = does it make some people a lot of money? If so, that's why. |
Why do bicyclists and backpackers spend thousands to save just grams off of their weight? | Let's say that you are a long distance runner and you know from experience that during an average race you take 35.000 steps. If you were to switch to a shoe that's 10 grams lighter, that's 10 grams less for you to lift in each step. Or 35.000steps x 10 grams = 350.000g = 350 kilos in total that you no longer need to l... |
Why is it only possible for the coldest temperature to be -273 C, but the highest temperature can be a decillion degrees C. (Referencing the chart posted in /r/space. | Temperature is basically a measure of how fast the atoms and molecules that make something up are moving or vibrating . If there's no movement at all, there's no way to have *less than no movement.* So we call that temperature, 0K, *absolute* zero. On the other hand, there's no real limit to how fast these things can g... |
How do people in wheelchairs manage to stay at a average weight while not being able to exercise? | They don't eat at a caloric surplus. Diet has a lot more to do with weight loss than exercise.Assuming an unpowered chair, just getting around each day is a massive upper-body workout.Each day is a massive upper-body workout. Combine that with them often eating healthily and participating in group activities, and it's ... |
How do we function normally with our vision delayed? | Most of what you 'see' is reconstructed from a montage of about 10 - 20 seconds worth of information, read about 'change blindness' |
Why do computers last years without overheating or dying.. but consoles have a high potential to burn out after overuse or consistent use over time. | Because a computer is built for more general use, and for a wider variety of uses from the average user who will just take it for what it is and use it for years, to the person who cracks it open, switches stuff out, adds stuff, etc. A console is for someone who isn't going to do any modifying, just uses it. They want ... |
Can someone please explain how family members can be "removed" and what that means? How can someone have a cousin 1,2,3 times removed? | It is about how many generations they are out from you. So, your grandfather's first cousin would be your first cousin twice removed because your grandfather is two generations above you. Your son's second cousin would be your second cousin once removed because your son is one generation below you.This question concern... |
Why does one pay after at most dining establishments rather than before? | Also fast food really introduced pay before you eat. Fine or at least decent restaurants try to upsell you. Ive had a Dennys waitress ask me if I wanted dessert after breakfast. That was weird. Fast food chains just try to move you along as quickly as possible and hope you don't complain.If you pay before you cannot ad... |
What is "speculation" and how does it drive up gas prices? | Speculation happens when people think gas prices will be higher in the future than they are now. If they think it will be higher in the future, they can make money by buying some cheap gas right now and selling it later when it's more expensive. So if a lot of people are willing to buy cheap gas right now, that means t... |
Why was Uber's culture a big deal? | First off, it's just human decency to care about how people are treated. But Uber's culture also did and would have continued to hurt the business, whether because they cannot attract the best employees due to risk of harassment or distaste for culture that overlooks that; they are at risk of expensive lawsuits from ha... |
How does Dry Cleaning work? Is it truly dry? | Yeah, and what is dry cleaned, what is laundered and WHY must they ask me my preference? How do I know what they're supposed to do? Button downs vs slacks, please. |
What is the marketing strategy with putting ads everywhere? Will there ever be an end? | You're not imagining things, we see an average of 3000 ads per day in the US. Why is this? People have shown over the last several decades that they will not pay for digital media like movies, TV shows, music, etc The internet has allowed people to have access to essentially free, unlimited media. This comes from both ... |
The validity of Anarchism as a political view | Anarchism works well on a small scale, because with less people, there will be less people violating the social order. In the modern world, it isn't very viable. There's too many people, and too many external threats to a group of people who aren't organized.This is not a good question for ELI5. It's literally demandin... |
Privatisation of the British railway system, the pros and cons. | The tax pay wouldn't fund rail fairs only those who use the railway this hasn't happened. In theory it would lower prices and create copetiton, this hasn't happend mostly due to franchising the line. If I'm to go form Edinburgh to London I will be on Virgin. If I'm to go from Llanelli to Caerdydd I will be on Ariva. It... |
When I'm driving on the highway and I see a weigh station, 90% of the time it is closed. Why is this? | An open weigh station used to be much more common, in my experience. Over time, enforcement forces have found that mobile patrols and random checkpoints are far more effective at catching violators. Truckers tend to communicate very effectively and, if a weigh station is open, trucks in violation will often detour arou... |
Why is insurance on rental cars so expensive? | It is expensive because most cars come back unharmed and it is an easy way to make money for them. Fear is a very strong advertising tactic and many renters will agree to it. I never get the insurance unless: 1) I am traveling abroad especially if driving is on the opposite side. 2) I am driving a race car Some car ren... |
Why does diesel cost more than regular fuel? | Diesel and gasoline are both taxed pretty heavily, regardless of where you go. Diesel also has to be further refined to remove the sulfur content . Sulfur was removed because it ended up being a significant pollutant, which ends up causing acid rain. The other major point is that the oil companies basically adjust the ... |
When, why and how did rice become such an indispensable part of Asian cuisine? | You could say the same for pasta, potatoes, wheat. Any root vegetable or grain. They're staples of diets because they're inexpensive, don't require great hunting or farming skill, don't spoil quickly, and give you the carbs you need. |
How is possible for my cell phone to have zero reception but still give me the option to make "emergency calls"? | The way it works is, if you make an emergency call, the phone will use whatever network it can get access to, even if its not your own. For example, lets say you're Vodafone and have no reception but there is decent Orange reception. The Orange network will be used to make the emergency call. If there is no reception o... |
How does Powerline networking work? | Because this is ELI5, I want to make a minor clarification: those kits can use your house's power lines to transmit your existing internet from one location to another. With the paired endpoints, your can think of your existing electrical lines like a really long network cable. You don't GAIN any internet access simply... |
If getting out of Earth's atmosphere is "zero-gravity", then how does the moon orbit the earth? | It isn't 'zero gravity'. It is free fall. The moon and Earth are attracted to each other by gravity. They orbit each other. Orbit is just a fancy version of free fall that results when something is moving fast enough perpendicular to the pull of gravity to allow it to 'miss' hitting it and just keep falling around it. |
Why does America use high fructose corn syrup instead of sugar? | It's also an extremely cheap food preservative. Corn grows everywhere in the US. And it's cheap. |
The Uberman's Sleep Schedule... | Say you need to let the dog outside to go potty. You could let him go outside for a long time, but then he'll just spend most of it sniffing around and laying down instead of going potty. Then imagine only letting the dog outside for a minute at a time. He'll be confused at first, but once he's used to it, every time y... |
why sometimes it is hard to tell whether something is wet or if it is cold. | Although the human body has many senses, a sense of wetness is actually not one of them. The way we tell whether something is wet is by using other senses, such as noticing if it is cold or if it is slippery. We are pretty good at this, so we fool ourselves sometimes into thinking we have an actual sense of wetness, bu... |
why are clowns so prevalent in Mexican culture? | Actually Clowns are not prevalent in most Mexican cities. There are exceptions, for instance Monterrey has an abnormaly large amount of clowns for only God knows why. In Guadalajara there used to be a TV show that had a well known clown . In Tepic same thing , Mexico City had and has a couple of clowns and one of them ... |
After a woman gives birth and the organs fall back into place, is it possible for them to go back in the wrong way? | They don't really go anywhere, they're just super squished. It's not like they detach from their original locations and form organ soup, and just hope for the best afterwards. It's just pressing on your belly, even if you push for a while, it goes back to its original shape. |
Why are general ed classes in college required regardless of your major? | You have a misunderstanding about college. It's not to teach you about a specific topic, it's also to make you a better-educated person in general, and thus more rounded and capable. And also, I'd hasten to point out, a huge proportion of people in technical fields are pretty terrible at English, math, and sciences. Yo... |
In countries where people only use bidets and act disgusted by toilet paper, what do they use at concerts/festivals in port-a-johns? | Indian here. We don't use bidets but toilet spray guns. * Overnight festivals are not common here, so generally people don't take a deuce in port-a-johns.* Port-a-johns usually have a tap and water mug like this. You clean with your hand + mug and then wash your hands thoroughly at the portable handwash station next to... |
How are racing games able to show the time with an accuracy of 1/1,000 of a second when they run at only 60 FPS? | Well, I don't know how games actually do this, but I can tell you how to do this as simply as possible. First, games have two different rates you may be interested in. Tick rate, and frame rate. Frame rate tells how often you draw the current game state to be displayed. Tick rate tells you how often you update the game... |
- Why are all the bottoms of clouds have a flatness about them while the tops are very non uniform? | It all has to do with the dew point. The dew point is the temperature at which water condenses from vapor into liquid. Above the dew point, water stays vapor. Below the dew point it condenses. Then you have the fact that temperature generally decreases as you decrease in altitude . So it it's 90 degrees on the surface ... |
How it is possible to shut down an entire county's Internet? | Sometimes, it's as easy as [a shovel.] The above is a funny story, but also helps to illustrate the point. It's all about access points. Your home has a router and if I can find the IP address for your router, then I can target it. In the case of North Korea, they have a very limited number of access points to the inte... |
How does a company pay when purchasing another company? | This somewhat depends on whether or not the target company is public and what the consideration for the merger is. If the company is private, it is relatively easy to deal with the owners. For a simple cash transaction, a bank check can be cut or wire transfer into the target shareholders accounts. If the target is pub... |
What makes buying insurance rational? | Good question. Diminishing marginal returns of the dollar. If you have a million dollars in the the bank, one hundred dollars is nothing. If you're starving to death, one hundred dollars is a king's fortune. Insurance allows you to transfer your low-value dollars to a potentially high-value area. When it comes to thing... |
Why are politicians drawn towards increasingly divisive issues (ie gun control) rather than the myriad issues everyone can rally behind? Why aren't we attracted to unity? | If you listen to a normal campaign speech , most of what they spend time talking about are things everyone agrees on. Unemployment should go down, the economy should improve, kids should get good educations, apple pie is delicious, etc. The thing is, there's nothing to spend time on when everyone agrees. They shake han... |
LI5, most of the answers I am reading are coming across as explanations for an average intelligence adult. I thought we were supposed to "Explain it like I'm 5" | Yes, this, absolutely this. The point of the subreddit isn't to literally explain it like you're talking to a five year old, it's to explain things simply and with effective analogies so that it can be understood by educated adults who have little to no prior knowledge of that topic, which is a topic that is difficult ... |
Why is it ten-folds more difficult to sing and play guitar at the same times as compared to just singing or playing guitar? | The guitar playing becomes ingrained in your muscle memory after a while so it's just second nature. Often when you're playing and singing at the same time, the guitar part is relatively simple and can be put on autopilot once you're comfortable with the chords. Also the guitar part and vocal part will also have simila... |
Why do men have so much more flatulence than women? Is it something physiologically different between the sexes, social more acceptable for men, or something else completely? | Yeah it's more on an individual level and based on consumption levels, type of diet, and digestion functionality, but on the average humans all fart/burp about the same amount each. |
Now that I am no longer a climate change skeptic, how do we get rid of all this Co2? | A simple & partial answer: plant trees.Tress photosynthesize more oxygen, take up CO2, provide shade, and do wonderful things for your soil. Their roots help open up your soil which allows CO2 to get in where it's converted to humus by various microbes. Soil formation can store *a lot* of carbon, the trouble is that it... |
Why are eating disorders commonly thought of as under-eating? Why is over-eating not considered disordered? | [Habitually overeating is considered a disorder] The social perception of eating disorders hasn't quite caught up to this, though. And just like how not everyone skinny has bulimia or anorexia, not every fat person has binge eating disorder. |
Why don't we like the taste of everything that's edible? | I think what you're asking is, why would I like carrots and not peas when both are edible and equally nutritious and beneficial to the body? I'd say the difference comes down to your exposure to certain foods during adolescence. Evolution hasn't gifted us with an innate understanding of what's good or bad for us. Some ... |
do you still produce vaginal fluid when masturbating if you still have your hymen...if yes...where does it go/end up? | As everyone else said, the hymen doesn't cover the vagina, and having sex just stretches it. [this video by Laci Green] explains more. |
Why is this test able to predict your answer | White hoe. I guess I'm a horrible person.Probably because the tool most people think of is hammer and the most prominent color in color memory is red. Otherwise I have no idea. I thought about a blue hammer.I'm in the 2%, but it was 50% correct", 'A recent Radiolab episode touched on the way we categorize items in our ... |
how is it that we live in the 21st century but still can't invent uncloggable toilets | Outhouses and porta potties are uncloggable toilets. They exist. If you changed your home toilet to some other transport method , you could have one. It's mostly due to the shape of the toilet that is used so that we can have small amounts of water in use, and no reliance on electricity, merely pressure.Modern Asian-st... |
Why do we find dark or offensive humour funny? | Brevity is the soul of wit. It is the most sophisticated of all the defense mechanisms. Humor takes something horrific and obliges you to see it in another light. I recently spoke at a memorial for my bro. I started with a joke. If I had tried to get through a sentence about the feelings I had for my bro. I'd have neve... |
why does going for a drive clear your head and help calm you when you're stressed out? | One must note that this method didn't calm Matt Barnes down when he drove 95 miles solely to beat Derek Fisher's ass at his house. |
Where did the misconception that radioactive waste glows green come from? | Probably from [uranium glass]. Before we knew that tiny amounts of it were highly radioactive, we used Uranium based glass for all sorts of stuff. It turns out it's a pale green. If I had to guess, that's where this idea comes from. |
How is the average life of long-life products calculated? Some LED bulbs have a 24.8 year life. That seems unusually specific for a product that hasn't existed that long. | It should be pointed out that LED bulbs don't last even close to the number they claim. I've gone through 4 of the CREE LED bulbs in about a year. They keep failing on me. Also, if you look at the LED tail lights of cars you'll see that they often have LEDs out on them. Usually it's the power supply circuitry that fail... |
Why do exporting nations want to weaken their currency? | Weakening your currency has the short-term effect that foreigners can buy your currency cheaper. When people can buy the yen cheaper, they'll buy more of it and be able to buy more Japanese stuff with those yens. It also has the long-term effect that stuff will become more expensive for the Japanese people. Usually, we... |
What is safer for the baby, a natural birth or C section and why? | Med student here. It all depends on the health of the mother and baby. If there are no complications a natural birth is preferred if the mother's pelvis is large enough to accommodate. There are of course risks of tearing though.C-sections are risky because well surgery always carries it's complications and also it wil... |
Why does a lower resting heart rate give a person greater stamina? | Low resting heart rate generally is a result of good stamina, not the otherway around. It means each pump of the heart moves more blood therefore your heart doesn't have to pump as fast at rest. When your muscles get tired it's generally a result of them exerting themselves but not enough bloodflow to supply them with ... |
Why Picasso is revered as an artist. | Before photography, painting was considered art for how close to reality an artist could make the painting look. With the development of photography, making a reproduction of real life was easy. In fact, any normal Joe with a Kodak could do it with the push of a button. Painting evolved its purpose -- instead of realis... |
Why did the US invade Iwo Jima if they planned to nuke Hiroshima and Nagasaki? | Iwo was strategic in that it could be used to land bombers and fighters so the naval fleet wouldn't be exposed in the sea. Nice long runways are much better for B-29s to land and launch from. The nuclear option wasn't really around at that point in the minds of the Navy. It was still top secret. |
Why does it snow at sea level in America, but not at sea level in Australia? | Look at the map and look at the latitudes of New York and Australia. The closer you get to the poles , the colder its get. Then look at the seacurrents nearby if they're warm or cold. You could look to New York it's get very cold there. The current there is cold. You look at London it's not getting so cold there. The c... |
Why does the tissue on the inside of your cheek heal/regenerate so quickly? | There's [an episode of SciShow] that explains a little of what's going on here, but the gist of it is that human saliva, and that of some animals contains a protein called [Tissue Factor] which they claim helps with the blood clotting process. They add that saliva also has [Lysozyme], an enzyme which can inhibit bacter... |
What exactly happens when I press "door close" on an elevator? Nothing? | It may appear like it doesn't do much in normal service, but I assure you the button has to work. In fireman service the door close/open buttons are very important and have to function in a certain way for safety's sake.It closes the door. It still has a delay, but every elevator I 've ever used shortens the delay if y... |
why in the racing video games you always started at the back of the line/queue | To give you a challenge. Winning without any contest is often less fun than almost winning but then losing. and its always less fun than a hard earned victory. The computer can't hope to beat you otherwise without blatantly cheating. And while in nearly every game the computer does cheat, it's very easy to catch the co... |
what exactly is "pi"? | Pi is the ratio between the diameter and circumference of a circle. You multiply the diameter of a circle by pi and it gives you the circumference, which is really pretty useful. This is also the ratio between the square of the radius and the area of a circle, too. That relationship is what makes it useful. If you know... |
Why does infrared light transfer heat when visible light which is more energetic does not? | IR is absorbed by our tissues and the temperature rises, whereas visible light with its shorter wavelength is largely reflected, so the energy isn't absorbed and the temperature doesn't rise. |
Why are aircraft carriers uncommon in most militaries | Also, manpower. A single carrier requires THOUSANDS of men to operate. And that's not even mentioning the attendant flotilla of smaller vessels that these ships really need to be a viable force - they may be the most powerful warships in history, but 99% of that power is in the air group. The ship itself is woefully ou... |
Why are minimum wages in the USA so much lower than other places? | I wrote a paper on comparative politics that touched on this. I found that the US is a massive country with a large population. In order to get votes across such a large demographic you need money, a lot of it. This opens the door to corporate influence and I don't think many corporations would be in favor of increasin... |
Why is it so easy to confuse left and right, but seems impossible to confuse up and down. | Think about it this way. If you flip 180 degrees and stand on your head you still think of the sky as up and the floor as down. If you rotate 180 degrees and face the opposite direction everything that was previously on your left is now on your right and vice versa. Left and right are purely perspective based while up ... |
Why is music/lyrics so much easier to memorize than other things? | You'll find that the lyrics actually aren't memorized, but the song is. If you've memorized an essay, you'll be able to recite pieces of it from all over. However with song lyrics, you have to sing the song to get the words. It uses a different part of the brain that remembers the patterns of the song to fit the lyrics... |
Besides the initial excitement about a new planet, what is the appeal of Proxima B if it would take so absurdly long to get there to study it? | If and when we develop technology that makes that distance not so absurd, it would be the easiest place for us to go. If there's a potentially habitable planet there, it makes sense for that to be what we're shooting for.Part of the goal of planet hunting is to get an idea of how likely it is that life exists outside o... |
Why do humans like symmetry and patterns? | Human beings, and most vertebrate life is bilaterally symmetrical. So for about 500 million years , life has been attracted to things that are symmetrical. Because that's what you breed with. A lack of symmetry usually means a genetic disorder, or an injury, both things that mean something is going to be a worse mate. ... |
Where am I safer during a thunderstorm with lightning: NEAR the water (shore), IN the water (swimming) or ON the water (boat)? | Well it's not in the water! Water is an excellent conductor of electricity! If there is lightning, get the hell out of the water! |
Why is PewDiePie so popular? | The simple reason:He wasn't always a moron who posted lame 5 minute videos of garbage. I remember the first time I watched his videos back in 2011, like most people I was watching either Happy Wheels or an Amnesia custom story play through. If you haven't seen his earlier content you should check it out. |
how countries like Taiwan, Kosovo, etc operate. | Day to day, these countries function like most other countries. They have their own legislatures and governments, they collect their own taxes, etc. In foreign affairs and trade, it gets tricky. For big unrecognized countries, often times legalese and fake names are used to get around the legal non-recognition. For exa... |
Why is the dirt taken out of the hole rarely enough to fill it back? | When removing the dirt, try putting it on a sheet of plastic. You'd be amazed at the amount that get 'lost' due to the grass and left behind otherwise. |
What would happen if a person were given a lie detector about something they don't remember? | A lie detector doesn't detect lies. A lie detector detects if a person thinks they are lying or not. |
With 48 hours of video uploaded per minute, how does YouTube survive? | lots of servers. lots of cables. everywhere. not only is it youtube, it's google drive, everything google really, think about that, that's just google for you. always adding new servers to the collection constantly |
Why time seems to fly by so much faster as you get older? | Most of what I have read about this suggests that the cause is familiarity. The older you get, the less chance there is for anything to seem really new and unusual. That is everything you have learned in life has become highly automatic. Most new things you run into can be related to some experience you have had previo... |
How does only part of the moon show up when its not full? | After reading the other answers, for those of you who can tolerate Flash content, here's a simulator : _URL_0_ |
