Where do my farts go when I hold them in? | Up your butt and around the corner. No really, Gas will just sit in your colon until you bear down to push it out. excessive gas build up can cause abdominal cramping though, so let em' rip! |
How vaccines work and why some people think they don't | I want to point out that the average lifespan of an American at 1900 was ~40 years old. At 2000 it was ~80 years old. No where else in history will you see life expectancy gain a +40 years in a mere century. Vaccines are considered the #1 reason why this is the case. It has saved more lives than people who have died in... |
Why do we get "Pee shy"? | Total speculation here: I think it goes hand in hand with the morning wood thing - we don't really notice it anymore, but there is a primal fear of leaving our scent in places that my be dangerous. Men get morning wood to prevent them from urinating in their sleep and alerting dangerous animals to their presence. We ge... |
Cellphone radiation and why people keep telling me it will give me cancer. | Cell phone frequencies are generally between 800 and 2700 MHz, this is the same range as radio waves which are literally flooding the atmosphere around us, and have been for nearly a century. Microwaves are what most people throw a fuss about, 'seeing as they cook food', but microwaves operate in that exact same freque... |
Sine, Cosine and tangent. | **SOH CAH TOA** Take a right angle triangle - and for a given angle you have three sides - the opposite, adjacent, and hypotenuse. [see this picture] see the A is the angle we are talking about - it's easy to see how opposite and adjacent get their names, and hypotenuse is simply the longest side. The sine/cosine/tange... |
why I blow cold air when I purse my lips, but warm air when I open my mouth. | It's air velocity. In addition to what people have mentioned, when you blow a fast stream, the low pressure created by the moving air draws in surrounding air which is cooler. |
Why we tend to wake up right at the good part of a dream | The 'exciting' part, especially it is sexual or especially satisfying leads to an increase in hormones or other substances in your body. It may lead to an increase in heart rate, breathing etc. This signals to your body that it is not at the appropriate condition to be asleep, and you therefore wake up. |
What exactly happens when you put metal in the microwave? | Ima give this a shot and say that the metal you put in the microwave can be thought of as a solid container filled with static non moving non flowing liquid when you place this metal 'container of liquid' in the microwave and turn it on, the microwave essentially causes the liquid inside to flow around inside the piece... |
Why does cough & congestion linger so long after the "cold" is long gone? | Coughs and congestion aren't actually indicative of being sick. They're responses by your immune system. Your immune system keeps those defenses up a little longer so that you're not so vulnerable right after you recover.I have this same problem. Looking forward to a response. |
How the universe is infinite and expanding? | The important thing to remember is that the Big Bang didn't happen in one place and now everything is expanding out from that central point. The Big Bang happened everywhere, all at once. That 'everywhere' explosion didn't make stars and planets and galaxies move away from each other, it made space itself stretch so th... |
If gravity is the weakest of the four fundamental forces of nature, how do black holes manage to become powerful enough to destroy or capture everything near them? | Because there are sooooooo much mass. Magnets don't naturally get very strong. Even the magnetism from the sun is quite weak, since it's just *very little* mass tha is *a bit* magnetic. The same goes for the other forces. Black holes have HUGE amounts of mass, and gravity is the only force that naturally builds up as y... |
Why don't most school buses have seat belts? | Conservation of momentum. Small thing going some speed hits really big thing going same speed. Path of really big thing isn't changed that much. |
How is time a "dimension"? | The important thing here is to not think about a dimension as if its some Star-Trek-type place you can go where Spock has a beard. A dimension is a degree of freedom, which is a fancy way of saying the ability to move in a direction. An easy way to think of it is how many pieces of information do you need to find somet... |
Why did Einstein say that if we could travel at the speed of light we would be able to time-travel? | The explanation I've always liked goes like this: Everything has a set velocity that is divided between space and time. As you move faster through space, you move slower through time, and vice versa. Your speed through space plus your speed through time is always constant, and is the speed of light. Light travels throu... |
How exactly does cancer kill? | Cancer cells reproduce rapidly due to a mutation in the cell's DNA, so one becomes 2 becomes 4 becomes 8 and so on. The resulting mass of caner cells is a tumor. As the tumor gets larger it will kill you, usually by stopping a vital organ from working. |
Why do all objects fall at the same acceleration? | It is because what makes things affectable by gravity AND resistant to acceleration is the same thing - mass. Seems pretty obvious but it is actually a big deal. Maths: Gravity force from earth F = Mass * Mass of earth * a constant / distance^2 Inertia equation Force = Mass * acceleration. Force on the object: ~~Mass~~... |
Why did Greek and Egyptian beliefs (among others) became mithologies but Jewish and Catholic beliefs became religions? | I'll throw out an idea. Mythology is the collection of stories and descriptions. Religion is the things people do. So for Christians, bible stories represent the mythology, while going to church on Sunday is the religion.Technically, Jewish and Catholic traditional stories *are* mythos, same as Greek and Egyptian tradi... |
Nuclear Fission Reactors: How is there a net gain in energy from both fusion AND fission? | If you're using one particular element, yes, one results in a net gain and one in a net loss. But you're not; fusion reactors use elements that release energy when they fuse, and fission reactors use elements that release energy when they split. |
Why honey never "expires" | Honey has a really high sugar concentration and this prevents microorganisms to grow in it. When you drop a bacteria in honey, the bacteria has a lot of water in it compared to the environment it's in. In other words, the difference in concentration between the inside of the cell and the outside is very big. This cause... |
Why I'm always tired even after 8-9 hours of sleep every night | How much do you exercise during the day? Are you an active person? I ask this because I normally am fairly active, and a decent nights sleep of 8 hours will sort me right out, but if I take a couple of days lounging around the house I will always be more tired after I wake up. In addition to wildgurularry's comment, th... |
Why is it so difficult to travel faster than the speed of light? | Skipping the explanation for why it's impossible to go beyond the speed of light, I'll address this misconception: > What makes light so special? Light isn't special. The speed of light isn't special because it's the speed of _light_. It's special because it's the _speed_ of light. It is also the speed of gravity. It's... |
Why do we still have an electoral college? | Formally getting rid of it would take a constitutional amendment, which requires the approval of 3/4 of the states. Smaller states that benefit from the current system wouldn't agree to get rid of it. |
what are Canker sores and why do they hurt so bad? | If you get them commonly, there's really no cure, but there's a few things that help. Mouthwash, though ungodly painful for a minute, will kill the pain for about an hour. There's also gels and liquids containing benzocaine which is a mild topical anesthetic from the -caine family generally available on your pharmacy's... |
The difference between the Republicans and Democrats. | The best way I have heard to think of it is to divide government into two major categories: economic issues and social issues. Today's Democratic Party believes in high levels of self-governing when it comes to social issues and low levels of self-governing when it comes to economic issues like taxes and welfare. The R... |
If nothing can travel faster than the speed of light is traveling to other galaxies impossible? | It's not impossible .if you are an immortal. As many people have already stated, you can get to another galaxy at subluminal if you don't mind the long commute. With suspended animation, cloning, uploaded/downloaded consciousness, some other form of life extension, it would be possible. Now if you wanted to get there *... |
How do knives work? | The edge of the knife acts like a wedge and wedges the cells apart in whatever you're cutting. It also helps that the knife takes all the pressure you are applying and focuses it into a tiny line. |
Why don't we sneeze when we sleep? | Just the other week I awoke in the middle of the night in a sneezing fit. I've had pretty bad allergies my whole life. I take Benadryl before bed, not only to help me fall asleep, but to help keep me from waking up midsleep sneezing. I take Claritin daily as well. |
Why so many people think the moon landing was hoax | I very much enjoyed the Mythbuster's episode on this. Netflix it if you have not seen it =]", 'Because the venture was huge and of course unheard of. At the time, the US and the USSR were in a restless race to space, always trying to "one up" each other with escalating achievements. Landing someone on the moon was a wa... |
What is the computer's BIOS and what does it do? | It allows you to change settings on your hardware before you load any operating system . It also handles checking things out and letting you know about problems that might keep you from using your operating system. Back in the day, you used to have to set up every little detail of your hard drive in the bios, now it's ... |
What's the difference between agnostic and atheist? | That is a matter of some debate. The atheist community likes to say [a]theism is whether you believe in gods, and [a]gnosticism is whether you are certain in that belief. But while agnostic atheists acknowledge they can't be 100% certain, anyone who takes on the atheist label is going to be very close to 100%, make the... |
Why isn't there thunder and lightning during snow storms? | > Why isn't there thunder and lightning during snow storms? Because you haven't been to Maine. |
why is gold so valuable ? | 1. There isn't much gold around and it's nice and shiny, so people want to have some of it.2. People know that other people want to have some of it . So they get some of that stuff and whenever they need money, there'll still be people around who want gold who they can trade with.3. There are also some other reasons wh... |
How does both fusion and fission produce energy? By that principle, couldn't we split and then put together atoms indefinitely for infinite energy? | You only get out more energy than you put in for fusion if you're talking about atoms lighter than iron doing the fusing. Similarly, you only get more energy than you put in for fission if you're talking about atoms heavier than iron. Stars actually die when they start making iron, because it keeps them from being able... |
Why does the American public value the ability to possess a gun so highly? | During america's formative years much of the country didn't have extensive or reliable law enforcement and the right and ability to defend yourself from criminals and nature was important and highly valued. This idea of violently defending yourself being an inalienable right of all people became ingrained in our cultur... |
why can people visit Chernobyl without effects of radiation today? | Radiation isn't all that dangerous. It takes quite a lot to hurt you. People are afraid of radiation because it is imperceptible magic that *can* kill, and can be spilled across a countryside like oil. The only place you could take a lethal dose in under a week is the reactor building. Some of the mess there is still e... |
The Monty hall problem- specifically one statement: Since the odds of choosing the car on the first round is 1/3, the odds of losing the game when you switch every time is also 1/3. | > specifically one statement: Since the odds of choosing the car on the first round is 1/3, the odds of losing the game when you switch every time is also 1/3. Wow! It took me forever to understand the solution - and you've just presented the simplest answer I've ever seen. Let's play the game - a million times or some... |
Why is the order of operations in the order that it is? | Since I somehow don't think this has been mentioned yet, the general mathematical understanding of this ordering is best expressed in terms of a [sequence of hyperoperations]. As other comments have alluded to, the ordering is entirely natural -- each operation is formed by using the previous one recursively. You can e... |
why don't planets travel around the sun in a circular trajectory? | So, consider a planet in orbit. It's got some energy from the fact that it's moving around, call that K. It's got some potential energy from being in a gravitational field, let's call that one G. So then the total energy T = K + G. This total can't change, because the planet and star aren't losing energy. So if one inc... |
Why Zebras weren't domesticated like horses. | Zebras are scary!!! The biggest cause of death in zookeepers are zebra bites. They tend to bite someone, and then not let go. There are records of persons being bitten by zebras, and then dieing from thirst as they are held there. Zebras also don't have the spine structure to be ridden. They have an arched backbone, wh... |
Why does the moon look so much bigger when it's close to the horizon? | The mind believes things on the horizon to be farther away than stuff overhead. Why? We're used to seeing clouds just a few miles above us, but the clouds on the horizon can be hundreds of miles away. So if we think it's farther away, and it's not, then it seems larger. |
How is Pluto, and very small celestial object that is very far from the Sun, able to orbit the Sun? | Others have already answered, but I was just playing Universe Sandbox and thought it might be interesting to post some images showing just how far out Pluto is. [For fun,] [and for science.] Not the most productive answer in the world, but it's interesting! |
How do the Reddit bots work? | They are written by people using the [reddit API]. Here's one written in Python: _URL_5_ |
What are the main differences between Sunni and Shia Islam? | I spent a year teaching in Saudi Arabia. It was the Shia who worked and were more open minded. I don't know if that's because they're the minority or if it was cultural.They disagreed about who should rule a long time ago. |
How we have a picture of the Milky Way galaxy? | There is no image of our Milky Way, they are either images of other galaxies as example of it or an artist's conception based on best current estimates. |
Why did we evolve to have one dominant hand and foot instead of just being ambidextrous? | It's not evolution so much as convenience. If you practiced using both hands for all your tasks every day, you could be ambidextrous, it's just easier to stick with the hand you're more confortable with. |
The Ireland and Northern Ireland conflict. | Wikipedia has a pretty good article on it called [the Troubles], it's a somewhat lengthy explanation, so rather than give you a complete rundown, read through the article and post back with any specific questions you have? |
Why do all the stars and planets look white when you're looking from earth? | As others mentioned, stars give off all types of light and all types of colors. Our eyes have two types of things for detecting light- rods and cones. Cones are very good at detecting differences in color. The rods are not as good as sensing differences in color but are good at detecting differences in the amount of li... |
Why are there much more right-handed people than left-handed people? | To take it one step further, what about those of us who are ambidextrous? I prefer to use my right hand for throwing things as well as anything that uses fine motor skills such as writing and drawing. However, I'd rather use my left hand for power swings and for some reason using eating utensils like forks and spoons. ... |
Why/how do stars "TWINKLE?" | You know how [heat haze] makes things on the horizon look all wobbly? Same thing happens to stars. Because it's generally cold at night they don't wobble *that* much, but they still wobble a bit and that makes them look like they're twinkling. If you were in space they would look like a constant light and wouldn't twin... |
where did the water on mars go? | Mars still has plenty of water remaining on it locked up with the CO2 ice at the poles, or as permafrost beneath the surface. Another interesting thing about water on Mars is that the southern hemisphere has more subsurface water than the northern hemisphere - by a considerable margin. A majority of the northern hemisp... |
Why does the statute of limitations exist? | Evidence degrades after a certain period. People have faded memories. Even alibis get increasingly difficult refute or confirm. Part of it is political in nature. Lets say Republicrats have absolute control over the government and Democans have a viable candidate against them. The Republicrats find a random crime a lon... |
Why does bottled water have and expiration date on it? | Actually it's not that unreasonable, UV rays begin degrading the plastic after not such a long time. If you leave a carton or something in the window for a few months you'll see it loose some of it's colour. This occurs because the UV rays can split bonds between the plastic monomers . When these monomers are released ... |
Why do planets orbit the sun on the same plane? | Actually they're not, although they are on the same plane *relatively*. They have all sorts of differenced and odd angles. However basic representations do not show this. |
If atoms make up everything, what makes up the space between an atoms nucleus and electrons | As others have helpfully pointed out, atoms themselves are made up of things smaller than atoms such as the nucleus and electrons which you mentioned in the very question. These in turn are made up of even smaller things , which are probably made of something even smaller, tho we are not sure. The thing is it is hard t... |
The difference between Communism and Socialism | If anyone is interested in discussing the political Isms, I'd be honored if you'd check out my subreddit /r/RedUnion. It is a place for peaceful discussion of the political isms. I am trying to build up a community of people who are willing to teach and to learn. :) |
Why are planets and stars only spherical and not any other shape? | Gravity pulls equally in all directions towards the center of mass. Gravity = gM1M2/r^2. Because the planets tend to have much more mass than neighboring matter, each point in the planet is pulled equally towards the center of that body, creating a sphere. That being said, because there is gravity pulling on each atom ... |
why you have to sneeze when you have a cold | Cold germs irritate the inside of your nose in order to make you sneeze because sneezing is a good way to spread the germs from person to person. It's evolution: the diseases that make people sneeze are the ones that reproduce and thrive. |
Why can astronomers see many distant galaxies but they don't know what's on outside of our own solar system? | Think of it like being in a field at night. You can see city lights off in the distance, but you can't see a tree 50 yards away. |
If the Earth is rotating eastward at 465 miles per second at the equator, how is it that planes flying East get to their destination in a reasonable time? | Because everything on the planet is rotating along with the planet. So when a plane takes off at the equator it's already going thousands of miles per hour relative to space, no matter which direction it's going relative to the earth. |
How does Wifi "work" | Here's my shot: Actually there are not notable differences between cellphones and Wifi. Both are using radiowaves, but with different strength and that affects coverage. Wifi home devices are using very little signal strength to operate and that's why the coverage is small. |
Why do I always wake up minutes before my alarm clock goes off? | Yeah, this happens to me too. After a long time of going to bed/getting up at the same time, your body just knows when to fall asleep and wake up. Once you set those boundaries, it's like your body can interpret the amount of time it within those boundaries that it needs to be fully rested. |
What is earwax and why do we have it? | It's like boogers in your nose. Dust and bugs fly in, your body deal with them by incasing them in goo. In your nose it's mucus that can either be runny or harden . In your ear, it's a waxy substance that should be cleared out with q-tips . Earwax itself isn't particularly special. It's made up of the same stuff as you... |
If species such as dinosaurs were around longer then humans (over 100 million years), why do they not evolve into more intellectual creatures? | Evolution is not an 'intelligent' process. It basically just generates random variations and the variation that results in more offspring, prevails.Additionally, there is no ctrl-Z. If the circumstances at the time of the dinosaurs favored power over intelligence, evolution will go down that way. Another example are ou... |
Why would raising the minimum wage help? Wouldn't it just increase inflation? | Well, that's not the typical argument. Typically, min wages are entry level jobs. The usual criticism of higher minimum wages is fewer entry level jobs; not labor or price inflation.It could. It may force businesses to raise the price of their products, but they might also respond by laying off workers. |
Why do black holes emit Hawking radiation? | I don't know what the answer is, but if you get no love here then maybe /r/askscience can help you out. |
Why do bacteria and viruses kill their host? | Bacteria are like a rampaging horde; they don't care about longevity. All they care about is reproducing as much as possible. And since each individual bacteria cell doesn't live for very long, each cell will try to reproduce the most in that short time that it's alive. This is best achieved by destroying the host in o... |
The difference between ®, ©, and ™ | Hypothetically, could the individual who created the Lil' Kim image that was lifted from this site for her album cover take legal action against her record producing company, since they did not use any of these annotations? |
Why exactly do animals like dogs and cats have such short lives compared to humans. | Same reason you hear dog years and cat years. They age faster. A dog is 7 years because they age 7 times as fast. Same thing for cats. |
If light is a wave, what is its medium? | Neither one of these answers are particularly great - they are correct, in a classical sense. When the other answerers talk about electric fields and magnetic fields, they are really talking about classical field theory. However, modern physics - specifically quantum field theory - has a different explanation. Light DO... |
Why does the USA still use imperial measurements and not metric? | I have heard that one factor has always been cost. Imagine changing every book in your house. Now make your house a large country that is in debt and is losing money. They aren't pressured that much but as US industry is significantly larger than Canadian industry their companies have the power to force parts be ordere... |
How can the Universe be both Infinite AND Expanding? | imagine an infinitely long rubber band, attach balls at regular intervals, now stretch the band , now distance between each ball has increased. |
Why can't we just terraform Venus, Mars, or even the Moon? | We probably could , but as you said it's very costly. It would cost MUCH more to terraform the moon then it costs to send out rovers or probes to other planets/moons though. And terraforming doesn't really give us the same scientific bang for the buck as rover research does.the vapor pressure of venus is too high so do... |
Could we do anything to survive a meteor impact like the one that killed off the dinosaurs? If so, What would we need to do? If not, why not? | If a > 1km asteroid hit us, we'd lose a massive proportion of the human race but I don't think it would be an extinction level event. We'd probably have global crop failures and an enormous die off but pockets of humanity might well survive because we have a remarkable ability to modify our environment that previous li... |
Why is there such focus on the exploration and urge to begin the process of colonizing the planet mars when our planet's Moon is so much closer? | we are not planning on colonising mars yet. we are looking for, amongst other things of interest, one key element: Water. There is none on the moon. Therefore any 'colonisation' would need to be sustained from earth and would be highly inefficient. If we find water below the surface of Mars we get a place outside of ea... |
Theoretically Speaking, Would a planet 65 million light years away, with a strong enough telescope, be able to see dinosaurs? (X-Post from r/askscience with no answers) | Yep! Relativity is awesome! It really helps you understand the concept of time in our universe with that! Now if you went to earth at a high speed and kept going to it, you would watch as shit really sped up! You would see everything go through time really fast! So yeah, the concept of time isn't really a past or prese... |
Physics tells us that energy can be neither created nor lost, so where does gravity's ability to cause motion, which requires energy, come from? | Something separates the stuff. That is either the 'big bang' itself, or some other physical, chemical or nuclear process. Energy is put in when the objects are separated, according to the standard work formulae, Energy = Force × Distance. Whatever separates the things provides the force . |
What is the difference between murder, homicide, and manslaughter? | Homicide is the general term: someone dying by another's cause. Murder is an illegal act, to kill with intent or extreme negligence. Manslaughter is killing by negligence, but not to the degree of murder.homicide - killing another human may or may not be criminal murder - intent to kill or death was a reasonable expect... |
Camera lenses are round... Why are the pictures rectangles? | The shape of the lens actually affects the way light enters the image, but it doesn't determine the shape of the picture. This means two things: first, light particles are circular because of the lens shape. If you look closely, or at a bokeh photo, you can see this effect. Second, if you remove the lens, you will see ... |
. why don't we fall out of bed when we are asleep? | Random fun fact, one theory on why we jerk ourselves awake while sleeping is because of primal instinct telling our body it's starting to fall out of a tree, and to thus to wake us up. > Another popular idea takes a more evolutionary approach to hypnic jerks, explaining that the spasms are an ancient primate reflex to ... |
The human origins, from ape to us. What happened to other human species other than Homo Sapiens? Do all modern humans come from the same individual? | We are apes. All the other human species became extinct, either because they died out or because they evolved into another species. Eventually there was just us left. And no, we don't come from the same individual. Individuals don't evolve, populations do. |
Why is life on other planets always thought to be more advanced than humans? | I guess the assumption that life on other planet is advanced gives people more the encouragement to look for them. Because let's face it , we are selfish and if this life on another planet can provide us with better advancements in our own planet then it appeals more us. |
The year 2038 problem. | That's pretty much it. Any program still running at that time that depends on a 32-bit integer to keep track of time will likely malfunction in some way. Those programs will have to be replaced or updated before then.Hopefully by the time that happens we will be on 64 bit programs almost exculsively. Heck we might be o... |
Why doesn't communism work in practice? | This thread is depressing. It's unbelievable how many people still buy into the whole 'human nature' thing to dismiss a political ideology.> why doesn't it work that well? You can't say that. Communism, according to the definition of Karl Marx, has never existed in an industrial society. According to Marx, Communism wo... |
Why is the middle class shrinking in the United States? | Robert Reich is all about this and just put out a movie, *Inequality for All*. It's a pretty good starting point if you can watch it. You can get it online and stream it in a couple places, too. |
Why do some people choose not to get vaccinated and not have their children vaccinated? | Because there's a lot of money and publicity to be had in making parents panic, pretty much. |
Where do ISPs get their internet? | Typically, 'small' ISPs will install cable in cities, between houses etc.. Bigger ISPs will install [under sea cable], satellites and other very expansive equipment. Usually the small ISPs will pay the big ISPs to be allowed to use their equipment.They don't "get" internet, they lay the cables to the servers that websi... |
What causes earth to tilt on its axis? | If you're trying to figure out how the seasons actually work in a song of ice and fire, it's magic. No double suns, no crazy tilting axis dance. As to earth's axis tilt, I can't answer. |
Why do you feel worse at night when you're sick? | The more active you are during the day, the worse you will feel at night. That's your body being fatigued from having gone about your day, plus being fatigued from your illness. It isn't uncommon for someone to feel absolutely fine upon waking up, but become progressively more fatigued as the day wears on. ** |
. Why do bees make honey? | honey is a bee's way of preserving food. it's comparable to what humans do making jelly and jam. |
If you were to die in space, would you decompose or stay the same? | The answer is likely you'd be freeze dried over the course of several weeks, and nearly all biological activity would cease. Freeze drying happens in high vacuum at low temperatures. If you died someplace in direct sunlight, the dessication process would be much faster, just a day or two. Your freeze dried corpse would... |
Why do we hear a ringing noise in our ears from time to time? | My ear, nose and throat doctor explained it to me like this. In your ear, there's fluid. Sometimes you eat something or take drugs that alter the amount of fluid being produced or they start to get rid of said fluid. What your hearing is the hairs & / bones & / cartilage vibrating at a certain frequency without said fl... |
If we were to allow division by zero to equal zero or infinity, would math get really messed up? why? | The best explanation I know is this: Multiplication is a shorthand for repeated addition. 4x2 is 4 +4. Division is shorthand for repeated subtraction. 10 5 is asking how many times you can subtract 5 from 10. So what is 10 0? How many times can you subtract 0 from 10? Certainly not 0 or 10. You could say infinity but t... |
What actually happens when we crack our knuckles/joints? | Also, I've done this for the better part of my life, and my fingers can sometimes be a bit numb and/or hurt. Is it because i crack my knuckles?", 'I wonder how many people began cracking their knuckles while reading through the comments. I certainly did. |
Why are internet upload speeds always much slower than download speeds? | Fiber internet usually has symmetrical upload and download speeds. That's why Google Fiber and other fiber internet providers only advertise 1 speed.Its also to slow file sharing of consumers as well as setting up servers in house. |
Why are pharmacists necessary? | My doctor prescribed a drug for me. As his writing is illegible, I couldn't tell what it was, I only knew what was being treated. The pharmacist pointed out that the prescription was for something I'm highly allergic to AND contacted my doc to get something else prescribed. So they saved my life and saved me a second t... |
What's the difference between volts, watts, and amps? | Watts is a measure of power consumption.Power.Current is a measure of flow of electrons and is measured in amperes.Voltage is a potential force.These three are all relative to each other, especially when you use them in a power triangle.P=VxI.V=P/I.I=P/V.So a 60watt light bulb running on a 110V system.I=60/110I=0.545 a... |
If black holes are so powerful even light cannot escape, now can we see them if the light reflecting them shouldn't be there? | We don't detect the reflection, we detect: 1. the absence of the reflection.2. the absence of any projection of stuff from them .3. the affect of the black hole on surrounding space . |
Why does fusion produce so much more energy than fission? | Although it's not a hard and fast rule that fusion produces more energy than fission, usually people are comparing hydrogen fusion to uranium fission. Fusion of light elements tends to produce more energy per mass of fuel used because the change in binding energy per nucleon tends to be greater for transitions from lig... |
Why do animals have mating seasons and why don't humans have one? | Having a defined mating season encourages the males to mate and move on. By having no external cues as to fertility, human males were encouraged to form long term bonds to increase the chances of passing on genes. Wikipedia quote on the subject: > Women concealed ovulation to obtain men's aid in rearing offspring. If w... |
Why does inbreeding create defects? | The short version: it doesn't. I just brings recessive genes to the surface. Some of those are very bad news. Inbreeding has a tendency to weed out bad recessive genes , while avoiding inbreeding lets them persist and accumulate. This can actually be a good thing, evolutionary speaking, as it permits multi-error mutati... |
