The difference between polygons and voxels | A voxel is almost a box. It has volume, takes up space, but it lives in another dimension where every corner of it is equally far away from your eyes. However, stack others next to it, and their co-ordinates can be represented in true 3d space. Think of voxels as sand weird sand, but it's not that complicated, really. ... |
Why do elderly people tend to drive slower? | I'm sure there's some science behind this, but just think about how old people are. Their reflexes aren't what they used to be. They process things slower . Senses are dulled to an extent - vision, hearing. And they're probably a lot more cautious than younger people. Younger have the reflexes and reaction time to navi... |
How are houses investments? It seems like they're just more expensive all around than renting. | Houses are investments because they generally appreciate in value. So, sure, maybe my parents could have saved a little money month to month by renting a place instead of buying that house for $40,000. But now they have a $150,000 home that's completely paid for. |
If a dog's hearing is better than a humans, why don't dogs seem uncomfortable when the TV volume is loud? | It's the difference between range and intensity. Dogs have a bigger range of hearing so they can hear pitches that the human ear can't, but the intensity is something separate and is more similar for both humans and dogs. Maybe this is a bad analogy, but let's compare it to being colorblind. My eyes aren't working hard... |
Why was a VW exec arrested while no bankers faced jail for the housing crisis? | So, this is probably a completely different situation, but didn't Iceland jail its bankers? Is there something that they specifically did that the U.S. bankers didn't do? Are the laws on banking different enough there to hypothetically cause a problem if a U.S. banker had lived there instead?", 'Because politicians and... |
Why are certain human senses more prone to annoyance than others? I.e. hearing the same thing over and over is annoying, while seeing the same thing over and over is not | Some people have different thresholds. For example some people are inordinately irritated by open-mouth chewing, and yet my wife WON'T STOP DOING IT. |
Why is Shakespeare taught in English class? | Because it's hugely relevant to English, even today. A few weeks ago I saw a good production of Hamlet, and it's simply amazing how many lines from that play are still in use today as common idioms. Shakespeare is one of the great English writers of all time. Loads of things that came after are influenced by his work, ... |
Why do I have to pay or jump through 1000 loops to get my credit report but cell phone and other companies can see it instantly? | What are all these hoops? Last time I checked my credit report, it took less than five minutes. Make sure you're doing it through a reputable site, such as _URL_1_ |
Why has no one created an electric vehicle with infinite range by putting large (somehow waterproofed) alternators in all 4 wheels of a car? | The concept is nice, and seems workable But, in fact it's not. The alternators themselves wouldn't be the issue, but rather the physics of the whole system. Electrical resistance keeps self-propelling generators from working indefinitely, as small amounts of the power are lost per length of wire. This factor is not the... |
Why is making fun of Jewish people seen as Anti-semitism whereas when people mock the prophet it is seen as freedom of speech and not islamophobic | Because Jews don't try and kill people when they do make fun of them, so there's less incentive to do it.Being antisemitic is utilizing still freedom of speech. You are fully allowed to do that. |
Why does the Sun and Moon look way bigger when you first see them rising? | If you go and measure the size with a [sextant] or something in [diameter]). There are several suggestions as to what causes this. Here are a few: #The domed sky We perceive the sky as a sort of flattened dome. This means we interpret the moon as *nearer* than when it's near the [zenith]. The change in size we perceive... |
What makes ending the cycle of domestic abuse "impossible" for a majority of abusers? | Maybe it's a commitment fallacy. From the abuser's view they might know that they did something horrible, but as long as the relationship isn't over they can make ist up to their victim. So they stay and try to make ist work, but it happens again. Then they feel like it becomes more and more important to make their vic... |
How can Netflix instantly stream very high quality/HD content but other online video players require significant buffering and much longer load times? | As well as the other answers here, also remember their player is extraordinarily good at matching your down speed. You'll notice it seamlessly switches between SD and HD as it is able to get more data faster. I notice if I download on my laptop while netflix is streaming on the TV, it can affect the quality of the vide... |
Why do fountain drinks at different restaurants taste different? | Also, find a store some time that has well water. Totally different taste. Just don't drink the fountain soda in Flint, MI. |
Why are most countries' borders' outlined in such ziggy-zagged patterns? Wouldn't it just be simpler to have the borders be straight lines? | Most countries' borders are based on natural boundaries, such as rivers and mountain ranges, that have tended to dictate where their peoples settled and what places could be defended. Respecting the terrain and demographics is one form of simplicity. In North America and Africa, straight borders are often the product o... |
Why diamond is a good conductor of heat but not electricity? And what is the actual mechanism of heat and electric transfer? | The mechanism for conducting electricity is shared electrons. Metals have electrons shared between atoms in their structure. That makes them good conductors. Heat conduction comes from atoms bumping into each other, so it's a function of the structure of the solid. Diamonds are uniform crystals, and wood is made up of ... |
What's the big fuss about Coachella? | * It's the first major festival of the season.* Hollywood types go there to get their pictures taken, and the media loves to go on about what the Hollywood types are up to. |
How Do Websites Know Which Website You Came From/Where You Go After? | Your browser tells it. **::Facebook::** Yo Chrome, suprised to see you here, where'd you come from? **::Chrome::** You know, just got back from Pornhub. **::Facebook::** NICE. Check out these ads about dating! EDIT- formatting |
How could it be that American schools are second-rate, but American higher education is the best in the world? | American universities have the best minds from all over the world, including all over America. American high schools just have whatever kids are in the area. You very rarely have a high school with enough prestige that people move across the country to attend it. So while there might be 1 or 2 bright kids in each high ... |
Why does Google Maps request WiFi be turned on when I'm not connected to a network | By allowing your device's WiFi to scan for access points, it can figure out the device's distance to each point without having to sign in to them. If you know the positions of the points, you can triangulate your position. That combined with GPS brings accuracy to even a few meters or less. |
why do some authors write books using a pseudonym? | If an author is known for, say, fantasy and wants to write sci-fi, publishers will often be uncomfortable with it. Fantasy is safe, so they want him to stick to what they know will sell. So one reason would be to break into a different genre. I'd imagine J.K. Rowling did it so her novel would not be compared to Harry P... |
Why are races usually measured in distance rather than time? E.g., 5k instead of furthest distance achieved in 15minutes. | Because to judge it you only need one person standing at the known finish point, instead of one judge per competitor who needs to be standing exactly where the competitor is after 15min , presumably the judge gets there by being an athlete who is as fast or faster than the olympic athletes you're measuring ", 'The fini... |
Why don't things 'count' anymore if they're not on the internet? | > Don't people just do things for the heck of it anymore without the need for digital footprint? Yes, millions, in fact. You just don't consider them because they're Not posting it on the internet. |
How did the United States' Republican party develop the position to be for drug control when generally they are for less government. | Because there are many hypocritical things in the Republican platform. They don't want government to control anything except the things they want government to control. Drugs and abortion are examples. Neither of the two major parties want less government , they just want different government.They want the government t... |
Why are other drinks not as effective in hydrating as water when they have water in them anyway? | Because they're not 100% water. 100% of something is generally more effective than less than 100%. Add to this many drinks have compounds that that might make it harder for your body to retain the water they contain. Alcohol and caffeine for example are things that generally cause your body to release water rather than... |
How can an image take seconds to load on my phone, but on the same connection Netflix can show a whole video with no buffering? | I'm a video engineer and support Netflix, Microsoft Smooth Streaming and Silverlight. If you watch closely, the first few seconds of a Netflix video are pixelated and blurry. Within 12 seconds, it will clear up. This is because Smooth will give you the lowest possible presentable stream while it fills its buffer. It ch... |
How do pilots manage to land on runways so perfectly, and not go 10 meters to the left or right and crash? | Another system is the VASI it's a visual indicator of whether the pilot is on the correct glideslope, too high, or too low. The ILS does not need to be active and any pilot with any skill level can use this for a good approach where visability is not a issue.I want to know how the hell they can see runways from the air... |
Why is CPU development slowed to a crawl? What is the next "hurdle" in CPU innovation that needs to be overcome? | We're pretty close to the limits of Moore's Law and standard physics where traditional materials and processes are used in chip manufacture, so we need to look at different materials and techniques if we want to get faster and smaller. [This crystal] can store 360TB of data for millions of years, but that's storage, no... |
Why changing amplitude in a simple pendulum has no effect on frequency | We have discovered a mathematical equation to calculate the frequency. It turns out that to figure out what the frequency is you don't need to know the amplitude, i.e. the amplitude is not inside that equation at all. Here is the equation to calculate the frequency: f = * √ You don't need to understand it - the only th... |
Why do we need to take all of our prescribed antibiotics even after we get well | > Why do we need to take all of our prescribed antibiotics even after we get well Because you're not well yet. You just *feel* well. But your body is still infected with bacteria, since some of them will be slightly more resistant to the antibiotics than others. Finishing the entire regimen of antibiotics ensures that ... |
Why does turning an electronic device off and on again often fix most of the problems? | Because when devices turn back on, they usually reinitialize everything back to known and sane values. The error happened when one of those values became unexpected and the device didn't know how to cope. How that value became unexpected is a wholly different topic. |
Why do we have different musical preferences? | If you're going to start that line of questioning: why do we enjoy music at all? It doesn't seem like other animals enjoy music . If you're not actually five, check out the book [Musicophillia]. It's not amazing or anything, but you'll probably find it interesting.This video sheds some light on this topic: _URL_1_ |
How do drug addicts stop being drug addicts? Why can some people do it and others can't? | People are addicted to drugs because they need to self-medicate themselves due to unbearable mental suffering, some of it conscious, some of it unconscious. Getting rid of this suffering by working through it is the only way out. The people who do this stop abusing drugs. The people that don't, either continue to abuse... |
Why does it take so long to execute someone on death row? | From what I understand, and I'm not a lawyer, there are usually automatic appeals that happen. This can lengthen the time a inmate is on death row. Also, laws change constantly, so there may need to be a new trial to take into account a new law. It actually costs more money for taxpayers to execute a criminal then havi... |
What is happening when we feel someone/something staring at us? | Throw away for obvious reasons When I was a kid, my house overlooked A LOT of bedroom windows. Seeing as how the computer was pretty well locked down, horny young boy me decided binoculars were a grand idea. I'd sneak upstairs after everyone was in bed, shut off all the lights, and peep through the binoculars into peop... |
Why does ray/path tracing lighting look more realistic than regular video game lighting? | Ray tracing is the use of actual, real world calculations of light, to represent light. This is very heavy for most computers. Rasterization is used for video games because it's MUCH easier on calculations and hardware and can be calculated much faster, though, it looks worse, most people can't tell the difference that... |
So 'when' the next financial crash happens, is it better for the average US citizen to owe lots of money or to owe no money to anyone. | I don't think that is right. If you owe, lets say, $100000 in mortgage to a bank, and the bank collapses, the banks creditors will come and recover the money you owe, and will take the house if you cannot pay up. - > You owe them money, you lose. On the other hand, if you have $100000 in the bank, and the bank collapse... |
How our lungs prevent/eliminate dust ? | As people have pointed out there is mucus to trap dust and whatnot and little waving hairs to push said mucus up to be swallowed/coughed up . Of note those hairs die off if you're a smoker and grow back and work again once you stop, hence why a newly quit smoker may get one hell of a cough as they are clearing out a lo... |
Why doesn't the one dollar US bill have no details to help determine if it's a counterfeit? | All US currency is designed to be hard to fake. However, some is made harder than others. One dollar bills don't have all the security features of a $100 simply because it just isn't profitable to counterfeit one dollar bills. It might actually cost a counterfeiter *more* than one dollar per bill to make them. And obvi... |
I am right hand dominant, yet my left hand has no problem keeping up when typing on either a keyboard or my phone. Why? | You learned how to write using your right hand, I'm guessing. And you learned to type/use your phone using both hands. Your left hand is just not trained in writing. |
Why are cell towers so big? | Imagine that a hundred people are hanging out in a park. They all want to be able to talk to each other, but the park is too big to just shout at someone on the other side. The solution you come up with is to have one person sit on a tall hill where they can see everyone. That person has a sensitive microphone so they ... |
Why do cicadas spend such a long amount of time underground? | Hard to be eaten when you are underground, and there's a lot easier access food down there Basically, maybe at one time some cicada grubs tried to make it above ground. I mean, there's generally plenty of grass and smaller insects to eat. But, there's also birds and other animals that love to chow down on large, slow m... |
Why is the genre fantasy always set in medieval times with knights and swords? | Because you're from a Western, European or European-descended country - so its same the reason why western history is featured in most of your culture and Hollywood movies. Because its part of *your* history. Go to China or Japan and you'll find that most of their fantasy works are based around their historical periods... |
What is 'octane' in fuel and how does it make your vehicle preform better or worse? | An actual eli5 answer goes something like this: An engine builds combustion as the piston goes to the top of the cylinder, fuel and air are inside and get compressed. At the top of the stroke your spark plug goes off and ignites the mixture, sending the piston back down. Onto octane ratings. In order to get higher perf... |
Why do you tip a % of the bill in a restaurant? Isn't serving two plates of lobster the same effort as two plates of Mac and cheese? | The whole concept of obligatory tips is retarded. The original idea behind a restaurant is you go there to pay people to give you good food in a pleasurable environment. That is literally why you go to spend money there. Then to expect that someone tips because you did your job, is *in principle*, illogical. It would b... |
can your hair really turn grey from stress? and how? | It can't happen overnight like some people claim. Stress is more likely to cause hair loss, and losing some hair can make the grey more obvious. Additionally, things that are traditionally considered stressful, such as having children, happen about the same time as aging would turn your hair grey anyway. The only direc... |
why I'm not bald despite the fact that I lose about twenty strands of hair in the shower a day? | I hope somebody has a scientific answer. My girlfriend is whining every time she combs her hair and gets around 10-20 strands curled up in a ball and says she's going bald. I have tried telling her constantly that it's normal and that you grow hair all the time, but noo let's buy expensive masks and oils and what not t... |
How does modern recycling work? How are containers filled with food handled? What percentage of recyclables are actually thrown out? | According to my friend that works in that industry food containers are thrown in with the normal trash because they can't be recycled. . the other stuff is sorted, some by hand, and bailed like hay and then sold to other countries that do the actual recycling. The USA doesn't have the facilities or the funding to do mu... |
How does Fort Collins connect its fiber lines to the internet? | Consumer ISP's are not the only ISP's out there. If you want a big multi gigabit or terabit connection, there's bigger tier 1 ISP's that'll sell it to you for $20,000 a month or more. |
What the reasoning is for store front businesses to leave one side of their double front doors locked? | The two I'm aware of are both maintenance issues. Doors/latches not working well and with the tight purse strings these days it cost more to fix than it's worth. I previously assumed it was to slow down crooks that would be moving to fast to read the use other door sign. |
How does a company like Facebook buy another like Snapchat | If the company being bought is public, they approach the Board of Directors and negotiate a buyout. This could be in the form of a dollar amount per share like what happened when Amazon bought Whole Foods, or this could be an exchange of shares, where two shares in the company being bought is now worth 1 share in the c... |
why do we sleep 8hrs on/16hrs off instead of, say, 24hrs on/48hrs off? | There's another more obvious reason a lot of people are missing, *other animals are awake in the daytime* and *humans can't hunt at night*. There's no practical advantages to being able to stay awake for one complete cycle.Also if you take away sunlight and live in almost complete darkness you adjust to a 48 hour cycle... |
Why strong, muscular animals such as gorillas don't need to lift weights to build a ton of muscle mass but humans do? | Genetics. ELI5 mode: You see Billy, although we say all men are created equal, that's not precisely true. Inside every cell of your body is a blueprint for how your body is supposed to develop and look. Your blueprint is a mixture of your mom and dad's blueprints, which is why your height, eye color, and other family t... |
Why do our eyes get "tired," but our ears/nose don't? | Your nose definitely gets 'tired' If you commonly wear cologne/perfume you'll definitely be aware of the scent as you apply it and for a few hours after you apply it, but after some more time passes you cannot smell that scent as acutely. But ask your SO to give you a whiff, and they'll absolutely smell whatever scent ... |
Is the sound of wind caused by the wind hitting things? Or the wind hitting its own particles? Or something else entirely? | When air moves past something, it creates eddies, which are unstable areas of disturbed, rotating air that form behind corners and obstacles. These eddies grow and shrink, move back and forth, and change direction randomly, and, in so doing, push the air around. This 'buffeting' is the cause of most 'wind noise'. |
Why humans newborns/children seem so helpless when compared to other species? | Humans have an extremely long developmental period because we're building a biological supercomputer. To fit that giant brain through our tiny hips, human babies are born pretty undercooked. So you have a species that is born early *and* develops slowly, leading to a very long juvenile period. The evolutionary trade-of... |
Why do Third World Countries have problems with possessing water, when the earth is 79% of it and we have the technology to purify water? | I live in a third world country for me acesibility to drinking water is not a problem there is plenty of water for everyone BUT sometimes the water can't be used for drinking because of dumping of industrial wastes without purification into water bodies this makes the water undrinkableDue to strict acts taken by the go... |
Why don't I stutter when I'm alone? | While I don't have an answer, I bring forth an anecdote. My dad has been in commercial radio for nearly 40 years. He tells the story of a news guy they had who would stutter like crazy, right up until he put his headphones on. As soon as he was listening to himself talk, he didn't stutter at all. Maybe there's an exper... |
Why do numbers to the power of 0 always become 1? | Look at powers of 3. 3^3 = 27 3^2 = 9 3^1 = 3 3^0 = < WHAT SHOULD GO HERE > 3^-1 = 1/3 If you follow the logical sequence, the only reasonable value for 3^0 is 1. That's because at every stage, we've divided the previous value by 3. |
Why are the latest phones upwards of $700-$800, while the latest tablets are only around $200-$300 | When talking about pricing your first thought should always be: What are people willing to pay? Normal users use their smart phones around a high 2 digit number or a low 3 digit number per day . A normal tablet user uses her/his tablet maybe 3 times a day. Additionally most people see smart phones as a basic need while... |
Why does water give off more steam after you turn off the burner? | It doesn't. Water vapor is transparent, the mist you see is condensed water in tiny droplets. The visible steam is cooler than water vapor so seeing more mist when the heat is decreased just makes sense. |
Can anyone break down what Endianness is all about? | The same bits are transmitted but the order in memory is different. This must be taken into consideration when moving between different systems otherwise you will interpret them incorrectly. Say a little-endian machine wants to store the two-byte sequence `0110 1001 ` into a network link that will end up on a big-endia... |
What does a Pre-pay penalty mean? | I think it means there is a charge on early repayment. Your bank expects to make profit from you by charging interest. If you pay back the loan early, they don't get as much interest. Therefore, they give you a penalty for repaying early, to discourage you from doing so and/or to offset the lost earnings.There are so m... |
The specific "reason" for Muslim women wearing hijab. | that's the exact question i got from a taiwanese friend while i met her in Germany. i'm a muslim and i wear hijab merely because i don't want to disappoint my parents. i grow up in a muslim family and society, that's why. i took my hijab off while i was in germany , cause i feel more comfortable without it. albeit, i a... |
How does wifi actually work (Internet 101) | At the physical level, the access point sets up a carrier signal wave that other devices lock on to. They broadcast their packets in sync with the carrier, and all devices listen out for packets addressed to them. They don't know in advance when it's safe to transmit, so collisions do happen, so a device listens for th... |
Why are there so few engineers and scientists in politics? | Simply put, the job of politicians in the executive, legislative, and judicial branches is to enforce **laws**, write **laws**, and interpret **laws**. So by definition, lawyers and those in law are more naturally suited for a career in politics. Business requires intimate knowledge of law; taxes, property, finance, et... |
How these type of walls stay intact when sea levels react the top. | They are designed to, basically. Water presses on walls with a very predictable force called hydrostatic pressure . Structural engineers will figure out how much hydrostatic pressure will be on the wall based on how tall the wall is going to be. Hydrologists will figure out how likely it is that the water level will br... |
Does flooding in a place like Texas mean their drought isn't a problem anymore? | I'm from country Victoria in Australia, the best I can describe drought is when the annual rainfall is below average, meaning that it is not at the recorded previous average levels, just because their is one big dump of rain does not mean that the annual rainfall average is being met. Another good thing to consider is ... |
How do companies make sure representatives don't vote against them after getting money? | Companies don't give money to politicians and tell them how to vote, they give money to politicians they know will vote the way they want. A lot of issues are divided along party lines, so it's not that difficult for companies to identify which politicians will vote which ways and back them accordingly. |
Why can't a car give more details with a dashboard warning light? | The mechanic can get much more data, with a reader, from the car's ODB2 maintenance data port. The car manufacturer only lights the MIL to tell you to take you car to someone who has a reader. There are thousands of codes, and cluttering up the dashboard with space for all the message details would not meet the car com... |
Why is it so hard for tinkerers to use parts of consumer electronics (smartphone cameras, etc) for their projects? | in addition to the below comments, manufacturers are doing whats called 'potting' components. instead of putting the chip onto a ceramic part, then having the part soldered to the board, they install the chip directly onto the board and place a blob of epoxy over the whole thing. This makes it impossible to remove with... |
How do we know for sure that cancer and other deceases aren't caused by being constantly exposed to small radiations from electronic devices and 3G, 4G, WiFi, LTE, Bluetooth-signals? | Wifi is just radio waves, a well researched technology we've been using for a long time. Cell phones emit a small amount of radiation, but studies by the WHO have shown that even extended exposure is safe.The signals you mention are non-ionising electromagnetic fields and yes we are constantly in contact with them in t... |
Why is 4:4 time the "standard" time in western music? | it makes it easier to 'chant' to and easier to predict. if theres a historian here then please back up the chanting aspect since all i can say is that we, as humans, like to chant things on a primal level dating way way back to the earliest armies. and the predictability comes from our brains always wanting us to be co... |
Why does an aircraft carrier store all the planes on deck? What happens if they need to scramble jets? | A lot of people aren't aware of this but the aircraft carriers have two decks, [forward deck blue arrow and angled deck red arrow]. Although both can be used to launch aircraft, when underway the forward deck is usually a parking lot. Planes can be parked in such a way that the back half of the plane is hanging off the... |
Why most Canadians seem to dislike French Canadians | A lot of people don't like the fact that politicians traditionally have had to pander to Quebec to get elected. So Quebec winds up getting a lot of money and favours given to them that other provinces don't seem to get. Not all people in Quebec are French, but almost all French Canadians are from Quebec. |
why is President Obamas amnesty executive order being brought before the Supreme Court? | NPR actually talked about this today. It isn't that Obama made an amnesty executive order, it is that it grants amnesty to such a large amount of people. So the courts aren't really deciding on if presidents are allowed to do this sort of thing, but to what scale they are allowed to go without congressional approval. B... |
Why do Men and Women have different size numbers for the same size article of clothing? Why not let them be the same? | I didn't know about shoes. My brother and I wear almost the same size About clothes I read in some article that men's clothes have standard measurements because during war times they needed to create uniforms massively so they created patterns and started having the official sizes. With women the sample size was very l... |
Does "0.999..." and "1" have infinite numbers between them? | Assuming you mean 0.9 repeating, no, there is not an infinite amount of numbers between 0.9 repeating and 1. They're the same number. It's well explained here:_URL_0_ |
How does Facebook find 'Friends you may know'? | Facebook is built on a *huge* 'graph' of data for each person, and *every* interaction feeds into that graph of data and relationships. Does your company have a Facebook page, and do you have any details of your company as part of your profile? It could be that the candidate visited or liked your company page and there... |
Why does the US have such a suing culture? | It is primarily a myth. Usually the 'horror stories' are the media sensationalizing facts. The most famous example is that lady who spilled coffee on herself and sued because it was too hot. The facts of the case weren't nearly as absurd as the media made it out to be and there is a great documentary on it called [Hot ... |
How can somebody like Tom Cruise be so successful in life and yet simultaneously come across as a complete nut? | Tom Cruise is really good at what he does. You could argue he always plays a similar character in his movies but that character sells. Personally, I don't think I've ever seen him in a movie I didn't enjoy on at least some level. Even his weaker movies are pretty enjoyable . This makes him bankable, meaning studios can... |
Why do presidential candidates typically say and do unintelligent things? | This has not always been the case. Unfortunately, American politics has devolved into a mindless sludge of keywords and directed hatred and this is ESPECIALLY true with republican candidates. None of the current republican candidates deserve to be president, not because I disagree with their views, but because they sim... |
Why can't we send the satellites we use in things like Google Maps to places like Titan or Mars? | I'm glad you mentioned Mars specifically because, not only are we doing that, but an imaging satellite actually managed to catch a picture of a rover on the ground, seen [here]. |
why do android apps want to see my media and contacts? | These are free apps, yes? Why do you think they're free? They want your contacts, and media and all the information they can get on you. Somehow this all turns into money on their end. That's the main way they make money on the app, not the ads you and everyone else ignore.Other than the already mentioned possibility o... |
Why is it that when I convert .wmv files to .mp4 files using VLC, the file size halves but there is no noticeable reduction in video quality? | WMV files and MP4 files both store compressed video. When you store a video uncompressed you have to store the color of every pixel of every frame separately. This gets big fast. If you watch a video though you notice that most pixels tend to be the same color as they were in the previous frame, and a similar color to ... |
Why chubby women sing better/ have better voice (especially in opera)? | I am a vocalist and I've been training for about 13-14 years in classical music . I'd like to agree with NerdyDasty about the misconception of weight being a factor of how well you can sing.I myself weigh about 190lbs but it makes no difference. As you practice, it reinforces your abdominal muscles, you diaphragm, and ... |
Why and how are rocket engines working in the vacuum of space? | Newton's laws of motion _URL_0_Third law: When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction to that of the first body. It sounds like to me that you are confusing the atmosphere as the second body. The second body is the bazillions ... |
What is attorney-client privilege? | Basically anything that you discuss in private with your attorney cannot be used as evidence against your or disclosed to any other person. For example, if you are in fact guilty of something you're being charged with, you can tell your attorney so that they can better build your defense, but they can't tell anyone you... |
how can you determine if a potentially valuable signature is authentic? | You need to find an expert on that person or field of history first. These are people who extensively study the person or field in question, and can compare previously authenticated signatures to the signature in question. Often, they can tell with a brief glance if a signature is fake/forged. If the signature passes t... |

why is it that all 6 zimmerman juries were all females? I thought they need to have a mix for a fair trial? | Both sides get to agree on the people.
