Why does my doctor prescribe me 800mg ibuprofen when he could just tell me to take 4 200mg pills? Is there something better about 1 800mg pill over 4 200mg pills? | /u/omfgzakum seems to make a lot of sense , but I think /u/HoHoHo_Its_Santa raises an interesting point about stomach upset. A tiny tiny fraction of any given coated pill is the actual medicine which is why both the 800mg dose and the 200mg dose of ibuprofen are probably the same physical size, so each of those four 20... |
The difference between "civil" and "criminal" court. | Criminal court is when someone breaks a law. Civil court is when someone feels they are owed something they haven't received. |
Venus is never a topic for space exploration but Mars is all the time. Why? | Venus is toxic and constantly boiling . Mars, on the other hand, is kinda chilly and has next to no atmosphere. Humans can't well colonize either easily, but technical equipment will fare **much** better somewhere where it's nippy, as opposed to somewhere where the atmosphere is made up of an extremely hot acid that co... |
What is the difference between permanent markers (sharpie) and wipe away markers (expo)? | Random tip: you can use Sharpie on dry erase boards. It won't erase when you erase the dry erase market, but if you apply Windex, it will wipe off with a paper towel. Was useful in college, we drew graphs a lot and used Sharpie to make the axis lines. |
Why does the internet hate the Big Bang Theory show? | It's not a well written show meant for smart people, it's a bunch of cheap jokes mocking nerds. |
why is bad eyesight so common even though it carried a huge evolutionary disadvantage until pretty recently? | > If I was born 500**,000** years ago, there's no way I would've survived with my terrible, awful eyesight Fixed that for you. If you were in a standard family 500 years ago, you quite possibly would have been fine. First, let's go way WAY back to when we first started ambling about on two legs. Odds you'd survive with... |
Does a man retain ownership of his semen after it leaves his body? | This begs the question - what do you mean by ownership?Biologically? Yes - it matches his genetic code.Legally? It's not considered a body part and more of a excreting body fluid so I would argue no, unless it was specifically retained for a purpose. |
Why are geeks and nerds becoming a part of the "mainstream" culture? How does this effect the definition of what qualifies a person as a geek/nerd? | I read an article a while ago where somebody said that geek culture and mainstream aren't actually integrated. It's more like there's a thick wall between geek culture and mainstream and the mainstream occasionally fires a harpoon through the wall and pulls something out from the geeky side into the mainstream side, an... |
How do cast saws not cut the skin, but effectively cut the cast off of a limb? | The saw isn't actually that sharp and it just moves a small amount in each direction so it kinda works like a file or a thin line of sand paper. It just tickles skin but it'll zip through plaster or fiberglass.By no means and expert but have had many cast in my days. The way a doctor once explained it to me was that th... |
Why is New York (Or any other similar American city) the 'go to' city to destroy in movies? (Action movies or otherwise) | I can't speak for *all* movies set in big cities, but here's what one wit said about *The Avengers* last year: > Rather surprisingly, it turns out that the alien infantry, while numerous and well armed, were completely unarmored as were their vehicles. A single well-placed 9mm round from Black Widow’s sidearm or even H... |
Why do we get an urge to crack our bones? | I regularly crack many of my joints and more recently my neck. I find that my fingers and neck, but mostly my back, feel looser once I've cracked them is there a physical explanation for this is is it just in my head? Also, over time I have found that the cracks/pops/click/sounds have become louder and more frequently ... |
How do people walk across hot coals? | Thermal inertia. Different substances transfer heat at different rates, and you probably know this, even if you don't realize it. Try this: you're baking a cake in a 400-degree oven. The instructions say the cake is done when you can press on the surface and it springs back. So you put your hand in the oven. What is th... |
Why Discovery Channel and similar knowledge channels are replacing their programs for non-knowledge related ones | In addition to the comments about low production costs and higher viewership with reality shows, you have to consider that the internet provides us with on demand information. We no longer need to wait for a TV about a topic we're interested in, we can just look it up.I hate it I hate it I hate it reality red neck stup... |
Why do the skeletons of people that died hundreds of years ago have perfect white teeth but mine will yellow within days without brushing? | They aren't, they just look like it in comparison to the rest of the bones, especially the skull because other bones are more porous than teeth and stain more easily.One word: Junk food. Our foods today are much more processed than even a century ago. Also, many people had bad teeth throughout history. That smiling ske... |
What do the gauges on a shotgun actually represent? | The gauge of a gun are a measure of how many lead balls the width of the inside of the barrel it takes to equal a pound. In other words, 10 lead balls with the width of the bore of a 10-gauge barrel to weigh a pound. It takes 12 lead balls with the width of the bore of a 12-gauge to weigh a pound. It takes 20 lead ball... |
why arent there any federal universities in the US? | My memory of my high school APUSH class is fuzzy, but I do recall this coming up and there having been a proposal to create a federal university that largely never got any traction, mostly because of the state university system was already largely successful. Yup, found it. [Here's a Wikipedia page] that has a bit abou... |
How do things grow on you mentally? Why can you start to like something over time that you initially hated or disliked? | Good experiences connected with said thing will create happy associations with said thing. For instance, you meet a person who is just seriously butt-ugly. As you spend time with them, you realize they are an amazing storyteller, and very generous, and etc. You'll associate that face with things you value, and therefor... |
How is Seattle's minimum wage 15$ an hour without a raise in the cost of living or inflation? | It's currently being phased in gradually - $11 this year, $13 next year, and $15 by 2017 so we won't see the full effects until then. Anecdotally, I've seen restaurant prices edge up by a buck or two on a typical $14~18 entree recently, but I've been trying to cook more anyway and this is a good motivation to do so . |
Why does your brain make the past seem better than it was? | Memory is biased for most of us because we prefer positive memories and experiences to negative ones, so those will be the types we prefer to think and talk about both when we're alone, and when we're with others. A certain song sparks a feeling of nostalgia because it was related to a special occasion or your first in... |
Where does data go when it is deleted off of a phone or computer? | Simple answer: It isn't physically deleted. Your computer forgets about that data in a sense, but the data is still there. It will still be there until some other data overwrites that location on the disk.It doesn't "go" anywhere. The most common way of erasing data is to just erase the filesystem pointer to it. Each f... |
What can Congress actually do to Facebook for censoring news feeds? | The first Amendment doesn't apply to Facebook. It only applies to congress, so they probably won't do anything. |
How do people spray paint graffiti on top of a overpass? | You climb and hold on for your life while you do whatever you're doing, tagging or bombing.These places are called heaven spots. |
Why is the battery life of a smartphone shown the least amount of improvement year to year in comparison to other specs (processor, display, data speed)? | Let's compare my current smartphone with my first smartphone. The CPU is faster. But the apps are more demanding, so the CPU doesn't feel faster. My data connection is faster. But in stead of the short pieces of text on simple websites, I now browse huge websites and stream video, so I still wait just as much. My batte... |
How has 1% of the population managed to accumulate nearly half of all global wealth? | A variety of factors are well described here, but don't forget the capture of our government by the wealthy. Are you aware that income made by investments is only taxed at half the rate of income made at a regular job? This and a zillion other loopholes that work to the advantage of the wealthy create a less-than-level... |
Why are so many scam call centers located in India? | A lot of people speak relatively decent English and labour is cheap. It's similar to the Philippines in those aspects as the Philippines also has a lot of call centres. As for why there's lots of scam centres, I would guess that people are less picky about what they're doing. Working at a call centre is already a relat... |
How is it that the remains of dinosaurs and other ancient living things were able to escape the fate of being consumed by scavengers, and decomposed by bacteria long enough to become preserved as fossils? | They often didn't. The vast majority of animals decomposed to nothing. A few were covered in mud or dust or other substances swiftly enough to prevent decay. |
How the NRA has so much influence when it comes to American politics | Because there's a huge number of people that support their stance on gun laws. The NRA has millions of member, and they're very vocal and active in defending their rights. |
Why do muscles like the heart and diaphragm not get fatigued like other muscles? | Because they are different kind of muscles. You have three kind of muscles: 1. Skeleton muscles, in your arms and legs. You control them. 2. Smooth muscles, in your guts and your pupils. You don't control them. 3. Cardic muscles, in your heart. They work by themselves but can be increased by the system .30% of them is ... |
why is extinction such a big deal. | Given that 99.9% of every plant and animal species that has ever existed on this planet is now extinct I honestly don't know if or why it matters. I know that we should try our best to not have a hand in destruction of habitat or loss of diversity but I can't help but have a nihilistic view on it. |
why we only go by solid hours for timezones. Could there techinically be a place in between time zones that is only 30 minutes ahead of the previous zone? | There are time zones that are 30 minutes off most others. There's no reason why there couldn't be. In fact there are a few that are 45 minutes off, too. There's no reason why there couldn't be a time zone that's any amount of time off most others. This has very little if anything to do with physics. It's just people de... |
Were Lena Dunham and Josh Duggar treated differently? | Well they're pretty different situations to begin with. Dunham was a pre-pubescent 6? 7? And legitimately curious about body parts. I mean, that's what I gleaned from reading the book; there was nothing sexual in it. The Duggar situation seems like it was exclusively about sex and sexual fulfillment.The right wing medi... |
Why can some people draw naturally? | I don't have a scientific answer to your question but I will recommend that you should start small. Attempting to draw the composition that you were trying to replicate takes a degree of skill you likely haven't built up yet. Maybe try drawing squirrels; then try practicing trees; you could maybe try practicing colorin... |
Why do so many websites ask me what kind of credit card I have when it is encoded in the number I need to enter anyway? | Employed in retail for decades. Background in computer programming and systems analysis. It always bothers me when any system asks you to tell it what kind of card you're using. First digit always tells you the card. 3-Amex4-Visa5-Mastercard6-Discover |
How do you read betting odds? | Also, please be aware of 'for' bets . 20 for 1 is not the same as a 20 to 1 bet. As has been previously stated, 20 to 1 winner means you get your $1 back in addition to the $20. A 20 for 1 bet means you get $20 total for the bet if it is a winner. I've seen this mostly on craps tables, but I would assume that the casin... |
How does anti-venom work, and why does it require more venom to be produced (or is this a misconception)? | Your immune system is not just for viruses and bacteria. They work on rogue enzymes too in this case venom. Anti-venom is essentially antibodies for venom. Like viruses they mark specific proteins that signal your immune system to attack the foreign bodies. But due to the chemistry of the venom, you can't rely on your ... |
The difference between "Decriminalization" and "Legalization" | Something that's been decriminalized means that it's no longer a felony or misdemeanor, but something lesser -- like a speeding ticket or something else that may incur a fine, but doesn't end up on a criminal record. |
Why did the indigenous Australians population decline so much? How did it happen? What were the causes? | I've got the slightest feeling you're fishing for essay research, but I'll bite The biggest decline in population was associated around the time of the 'stolen generation'. This was the Australian government's attempt to systematically breed out indigenous Australians. It included forcibly removing children from their ... |
Why Can Dzhokhar Tsarnaev Be Sentenced To Death (For The Boston Bombings) When Capital Punishment Was Outlawed In Massachusetts In 1984 | Long story short Massachusetts doesn't have anything to do with a federal case", 'He was charged with violating federal law. Federal law allows for the death penalty in certain cases . His case was a case in which a guilty verdict can allow for the death penalty.Because it's a federal crime and federal laws allow for t... |
Why are Graphic Cards like Quadro 6000 so expensive, even though they dont look like something that special? | You can't tell how powerful a chip is by looking at it. Smaller chips are often more powerful than bigger chips.Because looks dont matter, it whats on the inside that countsWhile investigating 10 bit color displays, I found that only the higher performance Quadros supported this display type. See: _URL_1_A lot of time ... |
if you are injured in Mars is there a risk of infection? | I'm not sure if I'm just misinformed here, but at what point did we conclude that Mars was sterile? I know that we have not been able to find any forms of life on Mars, but I hadn't realized that we'd made the assumption that this meant there was none And to parrot what other people have already said, yes, there is a c... |
EFI5: Why are upload and download rates not the same? | Because it isn't the cable that matters; it's the equipment on either end of it. And that equipment adheres to a standard These standards are designed for *consumer* broadband applications, and as such, they are designed for much higher downstream rates than upstream rates, because *consumers* are likely to do a lot mo... |
Why aren't all major national decisions made by a "yes/no" vote by the people? | Leaving aside the sheer number of issues the people would constantly be voting on, the problem is, people are biased, misinformed, and stupid. Everyone has an opinion. Most of these opinions are worthless. Just because a majority of people want something doesn't make it the right thing to do. It's called the tyranny of... |
How do you know that the amount of gasoline displayed by the pump is actually the amount you are receiving and you’re not getting ripped off? | Check the pump for a recent inspection sticker. They are pretty tightly regulated and required to be tested once in a while. That said, it's actually fairly common for the numbers to be off significantly. Sometimes this is intentional, sometimes not. If you think you're being shortchanged, you can complain to whatever ... |
When you're hungry and your stomach is "growling", whats going on in your stomach/intestines? What is growling? | Nothing unusual, it's just the walls moving about The growls always there, it's just louder because it's empty and more echo-y. |
Why do scientist assume the big bang was the beginning of the universe and what do they think happened before it? | I doubt that many scientists do assume that. The basic idea is that when we look out into the universe, we see that everything is moving away from everything else - at least on a large scale. This means that in the past, everything was once very close together - all squished together in one place. All of that is actual... |
Why are Republicans against giving the LGBT community equality? | Cause the government spends all of it's energy pretending to be useful and milking whatever funding they possibly can for it's maximum personal profit. They have shown by opting out of anything they force on us that they are not interested in us in the slightest. |
why are semi truck engines diesel, while passenger cars' are gasoline? Why are there no gasoline big rigs? | Heavy trucks in the U.S. were gasoline engines until the 70's when they started building diesels. One of the reason for this is that in the oil refining process you get a wide variety of fuels from a barrel of oil, such as gasoline, diesel, kerosene, jet fuel. Since there was an abundance of diesel at this time the pri... |
How come when a camera is pointed at a monitor, it looks like there are lines in the picture? | It's an optical illusion caused by the refresh rate of the camera. People in this thread are focusing too much on the properties of the monitor. It has less to do with the refresh rate of the monitor and more to do with the camera. The important element of the monitor is that the images on the monitor are not static. W... |
What would happen if, in this age, a country fell under a personal union with another country? | This actually kind of exists: the French president is simultanously Co-Prince of [Andorra]. But as /u/JimDixon says, that doesn't mean that the countries would unite, it's just an additional job for him. |
Why does the search for alien life focus so much around the existence of water? | Because the only life we know of is deeply associated with the water molecule. Yes, you could come up with all kinds of theories about other types of life that don't need water, but there's zero evidence that that could actually happen.All life on Earth is based around carbon and H20 so if extraterrestrial life exists ... |
How are bows and blades treated under US law? | It depends on the location. I live in New York and crossbows recently became legal again. Long and compound bows have always been legal. I went to college in Connecticut and I was told you can possess a blade longer than your palm is wide, though that seems a bit arbitrary considering that's different for everyone. The... |
How are we so precise about time, to the point where we skip skipping a leap year every 400 years, when our reference points are millions of miles away in space? | Because otherwise beginning of seasons would stop being aligned, which would mean that farmers would have hard time planting crops and church holidays would eventually start overlapping. These were at least the first reasons for leap days. Now that we are highly computerized and expanding beyond Earth, it's good to kee... |
What is a 401k and why is my job offering it to me? | First of all, 401K is an investment account for your retirement, basically you put away money into this account consist of investment options , and depends on your company's policy, they may give money to your account for FREE! Most company do a 4% match, meaning, they will put in money equal to what you put in, up to ... |
Why are most images from space B & W when we have so many tiny, light, color, high resolution cameras on the market? | Don't forget that most of these probes reach there targets almost a decade or more after being launched. Rosetta for instance was launched 10 years ago in 2004. |
Why do people have "neck beards" when the term is normally used as an insult? | If it's a possibility, someone thinks it looks good. Some people think mullets look good. Some people think 'the Canadian tuxedo' looks good. Some people think worn out thrift store t-shirts worn with a scarf and beanie in the summer with their scruffy beard, skinny jeans and horn rimmed glasses look good. People are t... |
What's the difference between laundry detergent, hand washing soap, and dishwashing soap? Why can't we have one soap for everything? | _URL_0_ The sunlight bar in the link is a very good soap. I'm willing to bet no black South African home is without it. We use it as bath soap, shampoo, dish washer, to wash clothes, general cleaning and as a laxative . It had other uses I can't recall off the top of my head. |
Why was the native american code during WW2 so hard to break? | It's mostly because they are languages that Native Europeans would have never been exposed to. Whereas most European languages share one of a few root languages, Native American languages such as Navajo are based off root languages that never existed in Europe. |
What is happening in Egypt? And why is it happening? | After the 2011 uprising the Muslim Brotherhood rose up to the charge with the leadership of president Mohamed Morsi. They were recently ousted from power by the Egyptian military in a coup d'etat as their leadership started to resemble dictatorship more and more and following this, their supporters have gathered to the... |
Why doesn't America teach their kids how to manage their money (do taxes, compare interest rates, etc)? | Education in the US focuses on academic skills, not practical ones. It's a long feedback loop. We rate schools based on academic test scores, performance is judged, budgets are made. Spending time on non-academic activities lowers performance in academic ones. We don't reward doing that, so we don't do it. |
Why is it that when you cut a magnet in half you get 2 magnets and not a South Pole and a North Pole? | Unfortunately, the only correct answer is: we don't quite know. [Newer particle physics theories say that isolated north and south poles should be able to exist], we just have no idea how make them. |
Why did Germany lose World War I? | First: while large part of Belgium was occupied, Belgium did not capitulate. The Belgian army held a frontline behind the Ijzer river. After years of war, a devastating blockade in the North Sea ,the loss of millions of soldiers and having a smaller industrial base than the allies , they suddenly faced revolt in the ho... |
My chemistry doubt since ages ? | Unfortunately, no. Atoms aren't that simple. To begin with, we can't really *see* electrons and neutrons because they're too small and their properties are such that they don't interact with light the way larger objects do. Because we can't actually see them, all our models and theories on atomic structure are based on... |
Why does soda taste better cold, and coffee taste better hot? | Leaving iced coffee and cold-brewed coffee aside for a moment, the fact that coffee is better hot just isn't correct. Your ability to taste things gets worse as things get hotter. If you're downing a cup of freshly brewed hot coffee to get you going in the morning, then fine. If you want to savour the taste, then you'r... |
How have scrubs, which are essentially pajamas, become socially acceptable for medical professionals to wear to work? | Scrubs are designed to be simple so that contaminants don't have any hidey holes", 'While we have scrubs here in Aus, I have never seen medical professionals wearing them around town like I have on a regular basis in the USA. |
Why do American employees get so few days paid vacation compared to Europe? | Large companies have a much larger ability to influence congress. Requiring large amounts of mandatory vacation time would be seen as harmful to the companies, as opposed to helping the workers. Legally speaking, we're not even guaranteed 10 days. Many companies give you absolutely nothing.It seems like hogwash when pe... |
Why do the Oscars tend to favour more critically successful 'artistic' movies, whilst the Grammy's favour more commercially successful 'mainstream' music? | I have this art conversation with friends all the time. People seem to be able to appreciate contemporary visual art , more than contemporary music. Jackson Pollock rarely offends but its musical counterparts , still does. People are always more turned off by music that doesn't fit their preconceived notions than film ... |
What's the difference between Manslaughter, Murder, First and second degree and all the other variants? | Very simple: first degree means there was planning and an act of premeditation ie you staged the murder to look like an accident. Second degree means you meant to kill someone, but acted in a spur of the moment fashion Manslaughter, both voluntary and involuntary, mean you acted in a way a reasonable person would know ... |
Why is the moon so perfectly spherical, when other moons in the solar system aren't? Does it have something to do with orbit? | As people have pointed out, it's mass/gravity. Anything heavy enough will pretty much turn into a sphere, because gravity is pulling equally on every point. That's why planets and stars are spheres^*. What I want to add to this is that Earth's moon is actually pretty huge. It's a quarter of the size of your planet. Any... |
Why is the Turing test considered at all relevant? | It's an excellent benchmark for the computer's intelligence in a heuristic capacity as opposed to high functioning calculators. |
Why does the US use letter while the rest of the world uses A4 paper? | I'm American: What on Earth is A4 paper?", 'i believe the answer you are looking for is the metric system. it makes scaling easier when going from one size to the next. unfortunately, i am no good at explaining things to 5 year olds _URL_2_Just like the metric system because it would be a big hassle to change. Why chan... |
Why do accents disappear when people sing? | It's rather arbitrary. With bands like the Arctic Monkeys, Sex Pistols, etc. you can clearly tell they're British. The Scorpions are a German band. When you hear the studio versions of their songs, it's hard to tell where they're from. But when you hear the live version, it's obvious they're German.Google "Korean pop" ... |
How do plants know when to flower? And how do flowers become fruits? | > How do plants know when to flower? I don't know if all plants do this, but in one of my biology classes we learned that plants measure the length of daylight hours to determine what season it is, and that tells them when to flower. They do this using a protein in their cells called phytochrome red that changes shape ... |
Why is biting your nails bad? | My wife was a nail biter. When she stopped, she noticed she did not get sick as often. It must introduce a plethora of bacteria into your throat that normally wouldn't get there. |
Why are gay men more susceptible to HIV? | Anal sex is more likely to tear the lining inside your rectal cavity, and since HIV is only transmitted via blood, the semen can enter the bloodstream via these tears. Because vaginal sex has natural lubrication, the risk for these types of tears within the vagina is decreased. It's actually possible not to transmit AI... |
why do we tear up when we laugh for a long time? | Not a doctor and probably shouldn't. Tear ducts respond to stress and hormones. When I yawn big my tear ducts act up. I can fake cry. Coughing can cause it. As can getting things in your eye. When crying from sadness, there is a hormonal release. Joy does the same thing. We can actually tell which is which because thes... |
What did AMD do wrong and why did they fall behind Intel in terms of processors? | For most of my life I was an AMD fan and only owned AMD and ATI products. The Athlon 64 days were the golden days of AMD where Intel had the awful Pentium 4 paired with super expensive and unnecessary RAMBUS DRAM. AMD processors were actually better than their Intel counterparts. Unfortunately Intel is a behemoth and p... |
What causes people to pass out when enduring harsh pain? (Getting punched, slapped, hit, etc) | When you get slappedIt's not the pain that knocks you out. It's trauma that makes your whole body shut down for a moment |
Why are there 360 degrees in a circle? Would there be any changes to mathematical eqts. if it was, say, 100 degrees? | Didn't change much for the 6400 mil scale. Don't confuse graduation or unit of measure with abstract mathematics. You'll seriously bake your noodle. |
What is the scientific explanation for making us feel "cuteness" when we see something cute? | We're hard-wired to protect the young to make sure the species carries on, even if it's not your own baby. Cute things reminds us of babies, so we are wired to like cute things. |
What's preventing people from setting up their own ISPs if they don't like Comcast? What actually enables an internet connection? | An internet connection is more than just putting a wire into the phone line and then off you go. When a internet order is requested, the ISP requests an engineer to connect your phone line to the ISP's DSLAM and this is what connects you to the internet. The ISP may or may not own the equipment your local telephone exc... |
What does the phrase "twice removed" or even "removed" mean when referring to a family member? | Maybe it's a cultural thing, but all of my parents' cousins are my aunts and uncles, and all my cousins' kids are my nieces and nephews. |
Can you explain why Russia doesn't want NATO forces close to its borders? | If you're trying to quietly break into someone's house you don't want the police parked outside. |
Why did human babies evolve to be so loud and demanding? Wouldn't a constantly screaming baby be an extreme problem for the safety/hunting of our ancestors? | I think your premise is wrong. When I watch a family of ducks, the ducklings are constantly beeping for attention. When a mother sparrow comes to the nest with a freshly caught worm, hear the little ones scream! I've heard a goat kid bleat incessantly for weeks after it had been weaned. We and our babies evolved so tha... |
How Do Some HOA's Get Away Charging $300+/mo? | You're comparing and condo and a house which means what you own and what is shared in your community is completely different. If you own a house you probably own the land you're on and the entirety of the structure. Which likely means the HOA is not responsible for maintaining anything on or attached to your property. ... |
Why are so many people upset by Common Core being taught in US schools? | I'm sure I'll get lambasted for this but when I was a child we also did not have the use of calculators until we began advanced geometry and calculus. Everything before that was hand calculated. I'm genuinely curious as to how these steps that have been created for 'estimating' purposes are more useful than just doing ... |
Why is restaurant food vastly more calorie dense than preparing food at home? Even at restaurants where they cook everything fresh, the calorie count is insane. | Lots of Sugar, breading, and fats. Butter, honey, sugar, gravy etc in the sauces, where most of the calories reside. If you have the grilled meats and veggies and they aren't drowning in butters or sauces, you should be fine.Restaurants rarely care about calories, they only care about taste so they will use more fats ,... |
Why does shaking soda release the carbon dioxide? | You're making tiny bubbles that serve as nucleation points for the dissolved gas. The liquid is basically saturated with dissolved gas that really wants to escape. |
How can a computer based on rules and logic generate a truly random number? | That's true. To generate a truly random number, one has to resort to measuring truly random processes in nature, like the decay of atoms. Truly random computations based on algorythms do not exist. For on this subject, watch _URL_5_ |
Why everything in old films moves so quickly | In the film Hugo, which deals with early silent filmmaking, we see a scene on a movie set with a hand cranked wooden camera. Just before the cameraman starts cranking a metronome is set going, a detail of early filmmaking I hadn't known of but makes perfect sense since the metronome could regulate the cranking speed pe... |
Why should I care if pandas go extinct? | > it doesn't effect me if they die or does it? It doesn't. The panda is a symbol. If you don't care if it dies out, you probably don't care if many other species die out. And these other species might be affecting you. |
- Why do we just not globally exterminate mosquitoes? Since this insect is a major cause of disease-spread and has no solo-purpose that can't be replaced by another existing insect? | It's all about the eco-system. If for some reason a type of fish carried diseases then killing off that species would have massive impacts on the rest of the species in the ocean. |
How does a car manufacturer decide which side of the car the gas cap should be on? | it's more convenient to have the gas cap on the same as the driver. however since some models are imported/exported and due to where you are, the driver could be on the left side or the right side, it doesn't make sense to also change the design of the gas tank/cap to be on the other side. so for the majority market, g... |
Why is card counting considered cheating by casinos? | Blackjack is a game of probability. By counting, you're bettering your chances and hopefully betting higher when the count is high ).
