- In the first Matrix, Neo asks for guns, how would he get to the other rows of guns? | > Are they just for show? It's a movie, it's all just for show. It looks cooler to have many rows, so that's what they did.This is probably better suited for /r/AskScienceFiction. If you are looking for an answer that fits in with the constraints and laws of a particular movie/game/work of fiction, that is the place to... |
I have heard that the Xbox One and PS4 are like high end gaming PCs. Why do they cost so much less? | * Bulk discounts: manufacturers specify one type of component and buy millions of them.* Consoles also have predictable ordering cycles: this means you can order parts many months in advance, parts manufacturers love this since they can order raw materials way ahead of time which makes them cheaper.* Consoles are desig... |
how come so many shows on Fox make fun of Fox so much? Why does Fox keep them on the channel? Shows like Simpsons and Family Guy. | Aside from the fact that the shows are very popular and make the company a lot of money, letting shows like The Simpsons and Family Guy make fun of Fox boosts the company's corporate image. By letting shows poke fun at the company, Fox seems like a "good sport" and like they don't take themselves to seriously . You'll ... |
How do PC games have "bad ports" when the games themselves were made on them? | Games made for consoles: * Are using different technologies, so a lot of code has to be rewritten for PC.* Have fixed hardware that developers can optimize for. On the other side, PCs have a variety of different hardware with different performance, and software can vary too * Have fixed screen resolution and FPS, compu... |
with glasses, can e.g. watching tv worsen your eyes? | No. The reason your vision goes bad is because they grow into an incorrect shape. Looking at a television isn't going to cause that to happen, and incorrect glasses are just going to cause eye strain. |
Why is it so easy to work yourself into an anxious tizzy, but it isn't as easy to calm down again. | My guess is that it's evolutionarily advantageous to be more scared and anxious than calm and happy. Fear can motivate you to do something now to save your life. Calming down quickly doesn't appear to benefit humans enough to have been favorably pressured by evolution. |
What happens when you reinstall your Windows OS over your computer? | The only risks you're really running are in deleting files you don't want to delete; re-installing Windows works best when you erase your hard drive and start over from scratch. Think of it like this: you buy some tropical fish, and every few weeks you scrub the gunk off the inside of the fish tank with a brush. This h... |
Why are drinks like coffee and tea gross when they are between luke warm and cold, but delicious when they are hot or iced? | I actually like the flavor of both at any temperature. It's probably just because I need the caffeine. According to [this] we have certain "channels" in our taste buds that affect the way we perceive flavor at different temperatures. These channels are called TRPM5. There was a scientific study done on the topic. Look ... |
Why do many herbivore's horns point backwards instead of forwards? | Many herbivores with horns such as those use them to show who the better mate between the males is. Or would be better to lead the pack. It is a show of dominance, but the intent is usually not to kill. You are right, horns facing forward would be better for killing, but that isn't what they are intended for to begin w... |
Why did people lose their retirement funds during the recession? Wasn't it protected or guaranteed? | Sensible investors didn't lose anything. The proper way to save for retirement is to automatically rebalance your portfolio as you get closer to retirement age. Basically there are some investments that grow faster, but can also lose faster in a recession - like stocks. Then other investments grow more slowly, but they... |
Do musicians get paid everytime one of their songs is played on any radio station at any given time? | They do get paid royalties, but it's not a one-to-one pay out . Basically radio stations report which songs they've played during what programs to performing rights organizations which then decide how to divide up the royalties appropriately and give each composer/publisher/author a fair share based on play-time of the... |
Why is the word ignorant used as an insult, when everyone is ignorant. | Ignorant is used as an insult regarding things you are supposed to knowWell to be ignorant isn't necessarily an insult. But if you are saying it to someone when discussing a topic you are essentially saying "you don't know what you are talking about". Which can be seen as insulting. But saying that you are ignorant abo... |
Why we dont forget how to talk when they erase our memories? | When who erases our memories? At the moment we don't really know enough about the brain to *intentionally* remove memories from one without also causing severe damage to other systems. But if we're talking in terms of accidental memory loss then it's very common for one to lose more than just memory -- challenges inter... |
Why don't people sense the pressure of the atmosphere? | It isn't our brain filtering out something constant. Everything on Earth, including inanimate objects, is being pushed on by that pressure, all the time. All that air above you weighs a lot. It's exerting a force on you, a huge one. So you, and everything else, need to push back. Your body is pushing out constantly wit... |
How does the 3DS work? | I assume you mean the 3D aspect? when the 3d is activated, the screen disaplays two slightly different images visible at different angles. one image is seen by your left eye, the other by your right. the images are such that they create the illusion of depth. |
how could the Romans build 220 ships in 45 days? | You really have to take into perspective of how massive the roman populations expanded to at that time. And it's not exactly to say they built cruise ships, but smaller more manageable ships and boats; *as well as* the high level of slave driving and forced prisoner labor that took place.slavery. it's the foundation of... |
What exactly gets lost when mass gets converted into energy? | Nothing gets 'lost' per se, that mass represents the energy that was originally bound up in the Hydrogen atoms. Helium atoms use less energy to keep everything together than two Hydrogen atoms, so some of that energy gets ejected from the newly minted helium atom. And that's how our sun shines. That little bit of mass ... |
Why is it a bad idea to put dental glue for braces all over your teeth to prevent damage or for less maintenance? | It's easier and less expensive to just brush and floss, but even if you could encase your teeth in a protective shell, you would still need to brush and floss to protect your gums from disease. People with crowns, which cover the exposed tooth and cannot get cavities, can still develop cavities around the edge of the c... |
What should I go to school for if I want the knowledge to fix audio equipment and gear? ( like synths, receivers, etc.) | Engineering, specifically electrical or electronic engineering. Luckily, Electrical engineering is a very broad field, so you could get your degree there and then decide later that you aren't super interested in audio equipment, but you'll still have a really great degree to fall back on in order to further your career... |
Why does the human eye see more shades of green than any other colour? | this is due to the Spectral sensitivity of the eye it perceve a larger intencity of green and red light than it does for blue, the eye has 3 type of colour receptors called cones and rods that are associated to the 3 primary colours, the amount of cones and rods for the 3 colours are not equal so you might perceve more... |
How can a telescope detect oxygen? | Spectroscopy. Different atoms and molecules absorb/emit light at different wavelengths. Spectroscopy is basically an analysis of the light we see coming from an object . We can compare that light to the emission patterns of elements and tell what a planet or star is made ofSpectroscopy. Atoms and molecules absorbed and... |
What are the origins of the Baptist church? | The original baptist church was started by a minister who had split from the Anglican church . From there it grew and spread, came to the new world, and became very diverse. Today it is not a guarantee that two baptists from different congregations will believe the same thing. The most unifying theology of baptists, an... |
Why can I never remember falling asleep? | Here's the scary thing: This must be what it's like to die, except you never wake up and have the memory of attempting to go to sleep. |
why we get goosebumps when we hear a particularly beautiful voice or a certain scene in a movie? | The human brain is pretty amazing; it doesn't have to actually experience something to respond to it. Some external stimuli can lead your brain to start acting like you are experiencing that scene in real life. This leads to the release of chemicals in the brain which cause the body to physically react. The reason you ... |
How can radio waves go through walls, but visible light can't? | Depends what the wall is made of. Various chemicals are transparent to various frequencies of light. Typically we also prefer walls people can't see through so we avoid materials that are transparent but you could choose the opposite. |
why do your pupils dilate when you take Psychedelic drugs? | depends on the drugs or your definition of psychedelic. if you mean sensory hallucinations then its because they generally act as stimulants and since your eyes are now processing more light back at the cerebral end and your heart rate is up to feed your brain , then you dilate this dilation is therefore twofold - your... |
Why are some former presidents referred to as former President and some referred to as President? | "President" is an official title, but it is also a job. If you were ever the President of the United States, you are entitled to use the title President for the rest of your life. Thus, everyone who was ever President is titled "President", but every one except Barack Obama is also a "former President"Just discretion. ... |
Why do sounds become 'distant' when you hang upside down? | Probably because gravity lets blood pool in some of the areas of your inner ear that normally aren't so full of blood, which slightly dampens how effective your ear drums are. Guessing. |
Why is that when someone sentenced to 20-30 year in court but sometime only need to serve a year or so? | Judges usually don't give a simple sentence, they usually give a fixed term over a variable term . The news reads "sentenced to 20 years", but really it is "sentenced to 20 years with parole eligibility after 8". There is a fucking colossal variation in the behavior patterns and temperaments of people sentenced for the... |
How do divers that don't have an oxygen tank not get brain damage from lack of air? | Mammals have bodily reflexes to being underwater known as [mammalian diving reflex]. Heart rates are reduced and our bodies let the outer layers cool so that it can conserve oxygen. As babies fresh out of the womb this reflex is generally very strong but we lose it overtime, free divers train to build this back up. Hav... |
Why do some businesses say no photos? | There could be many reasons. 1) Taking photos is discrating to the people working. This is common for performance venues. 2) Taking photos may capture information that the business is keeping secret. 3) The business may make their money by having people come into it to see what they have. You get this a lot with art ga... |
Why must an FCC approved device accept interference that may cause "undesired operation"? | It means that the device has a low priority on the hierarchy of communications, so if something is interfering with it, tough titty. As an example posted on a thread I found about this, someone pointed out that amateur radio and wireless LANs share a frequency band. Because amateur radio is on a higher priority than yo... |
Why is bureaucracy in India so stifling, and why does it seem to be accepted by everyday people? | A lot of things in India are blamed on the British . When it can't be blamed on the British it's blamed on Pakistan. When it can't be blamed on Pakistan it's blamed on India's less developed/poor states. When not them then it's the next village over, or the other political party, or that guy eating a hamburger. While i... |
what does it mean to wear your heart on your sleeve? | It is a metaphor. It means that you allow your emotions to show- people can tell easily if you are happy, sad, angry, etc- ether by what you say, or how you act/compose yourself.It means that you're very emotionally open and willing to share your deep feelings with other people. |
If water makes up 70% of our earth and we have things such as water purifiers, why are we running out of drinking water on our planet? | We're *not* running out. The problem isn't the amount of drinking water, it's the *distribution* of the water. Most developed countries could probably hydrate their population 50 times over, if they wanted . Whereas, for example, in hot African countries where water is scarce, contains diseases and there is little tech... |
why is it that we are able to subconsciously control our bladders when we sleep? How is it that we manage not to piss ourselves? | Your body releases a hormone while you sleep called vasopressin which inhibits the production of urine. You produce less urine while you sleep, and it's a thicker, more dense liquid . People who have lower naturally occurring levels of vasopressin have to take a synthetic form of it called desmopressin before they go t... |
Why are dinosaurs marketed so much toward kids instead of other animals? | Dinosaurs only exist in the toy aisle of the store. For contrast, ponies are a real thing. You can actually buy your kid a pony, and teach it all about how much a pony eats and the work involved in picking up after a pony. There is a mix of upside and downside with a pony. Where I grew up, many kids had a "pet" cow as ... |
How do basic circuits work, what is voltage, resistance and current? | I think of it in terms of water. Water flows from high ground to low ground. Electricity flows from negative to positive. A river is when you have a channel for the water to move through. A circuit is when you have a conductor for the electricity to move through. Damn the river, the flow stops. Break the continuity of ... |
Rugby and how its played | As an American, I hope someone will answer this question seriously. I'd like to be able to comment on that ludicrous display last night. |
why do oceans exist? | Oceans cannot be absorbed into the sea bed because below the sea bed there is bedrock and the water is already saturated within the sea bed. Open water sits on top of the water within the sea bed. |
Why do Americas call "Back Bacon", "Canadian Bacon" and when did that start? | It is called both Canadian Bacon and to a far lesser degree Irish Bacon or Back Bacon in the US. This is because they are the cuts that the Canadians and Irish call bacon. They are from the pork loin which is the back muscles toward the rear of the pig. But what we Americans call bacon is from the belly of the pig. Can... |
Why do we use the word "late" when talking about deceased people? | One lesser-known meaning of "late" is "recently, but not any more". If, for example, you say, "A man late of London," you mean he used to live in London until just a short time ago, but now he lives somewhere else. From that came the expression "The late Mrs Smith," which was used as a euphemism to avoid using the word... |
Why isn't a Bluetooth connection instant? | Whenever two electronic devices talk to each other they go through what's called a "handshake" - basically it's the two devices trying to negotiate a common ground and make sure they can continue speaking in a stable fashion. > Device A: "Hey! Hey is anyone there?" > Device B: "Yeah, I'm here. Hi, I'm B. Wanna talk?" >... |
Why is shampoo almost always colored but conditioner is almost always white? | Hm, I guess that hasn't been my experience. Besides white I've had pink, blue, and yellow conditioner. Maybe it's just the brand you're buying? |
Who notifies Google about newly made roads for their maps? | There are companies specialized in this sort of thing. They monitor local government announcements, planning permissions, etc., and when they see a new road is being constructed, they will go and collect the data. Google's maps business is big enough for them to own some companies like that as a subsidiary, but sometim... |
What is the difference between being a line cook and a chef? | Cool, that makes sense. I recently became the kitchen manager of my restaurant six months ago, the only reason why is because everyone else who worked there quit. But I make new recipes constantly and everyone calls me chef, but it feels weirdA line cook follows a recipe to prepare a dish. A chef sees what foods are av... |
What's the difference between the words 'Muslim' and 'Islamic'? | "Muslim" refers to people. "Islamic" refers to everything *but* people: "Islamic art" "Islamic architecture" "the Islamic world." Like thatA "Muslim" is a follower of Islam. "Islamic" is used to describe anything related to Islam.Islam is a religion and it's followers are called Muslims. Something that is called Islami... |
Why does the U.S. always side with Israel over Palestine? | There's no diplomatic way to say this — Israel is considered to be culturally similar to the US, it has a representative government with stable political institutions, and American Jews are an important domestic political constituency.This is slightly less to do with US policy and more with elections, but it is worth n... |
Why do those cheesy pictures that get shared on Facebook always looks so grainy and pixelated? | They tend to pick up artifacts because the original image has gone through a chain of hundreds of computing devices which used different file formats and resolutions and so on. People do stupid shit with their files like opening them in Paint to edit them and then saving them in a different format. A lot of image forma... |
why progress bars always hang on 99/100% | Progress bar values are basically made up by the developer. For some things they work pretty good. If you are downloading a 100MB file and have finished downloading 70MB then saying you are 70% done is pretty easy. For things like installing a game, where you have a huge number of files of different sizes it gets a lit... |
How do spark plugs break car windows while rocks can't? | concentration of force. a nail can break a window. a palm doesn't, even if there's more force applied. |
. Why is voltage proportional to resistance when voltage drops after going through a resistor | It's not perfect, but the water analogy is a reasonable one. You can think of resistance as the size of a pipe, with larger resistances meaning smaller pipes. Voltage is proportional to resistance as long as current is kept constant. Constant current is analogous to constant flow, so that means that if you take two pip... |
How come video compression is getting better all the time, but sound files are still the same size as ever? | Audio compression is already really good, and has been for ages. People tend to be a bit more picky about audio quality than they are about video quality, for some reason. The bottom line is we don't really need better compression for audio files. |
Online Universities and their value over a traditional degree. Is a degree from one just as good from the other? | In the UK this depends entirely on the reputation of the University. We have the Open University, which was established in 1969 specifically for distance learning regardless of previous qualifications. In 2009/10 it enrolled 250,000 students and in 2011 was ranked in the top 40 UK Universities and top 500 globally - qu... |
What is the IMF and what does it do? | The International Monetary Fund deals with money problems on a world-wide scale. Think of them like a bank, but for countries not people. It started by a bunch of countries putting in money, and other countries could borrow this money if they promised to change their economies to be more 'effective'. I put this in quot... |
Why should we keep funding NASA? | > So, what makes these investments worth while? We don't know ahead of time, which is the biggest reason. Advances made in the space program are both obvious and subtle . It leads to detecting threats to our infrastructure and insight into our environment . The point of exploration is that we don't know what is out the... |
What makes PewDiePie so popular? | The reason you find him childish and pointless is because his videos aren't made for you. PewDiePie is actually something of a genius because he knows his audience inside and out and knows how to entertain them. His target? Teenagers. They eat his stuff up because they're still at the stage where randomness is the funn... |
Why are emulators so tricky to make? | Emulation does not improve as the technology gets older. Emulation's difficulty depends on how different the platform is that is being emulated from the platform you want to emulate on. In the end it all comes down to the fact that emulators are non-profit, unofficial projects. Creators don't have the necessary documen... |
With an inherently limited number of sources from past centuries to examine, will there come a time that we "run out of history?" | It's doubtful. The more we find out about history the more wrong we tend to discover we were about things. Even very recent history is full of misconceptions, falsehoods, and propaganda to dig through.It's certainly possible that we will eventually uncover every single piece of historical evidence in existence, althoug... |
Why do kittens go into a state of paralysis when grabbed by the scruff? | you can also use scruff training for teaching discipline, but only for kittens not adult cats. I wish I'd known this when I adopted mine as kittens. My 3 cats are all rescues, grew up with no mum so they have a bad habit of biting, nipping & generally bratty behavior that kitty mom would discipline out of them. _URL_0_ |
Why are batteries charge measured in mAh instead of Coulombs? | No real reason. It's just because that if you know that your circuit draws 100mA and your battery has a 1000mAh capacity then you know that your battery is going to last 10 hours. Easier than using C and then diving by 3600 second to get the number of hours.\r\rSame reason we measure energy in kWh instead of J |
How are phobias acquired? | It's kinda like a psychological allergy. With an allergy, your immune system is overdoing a normal healthy response. A phobia is when generally healthy fears are exaggerated. When you have a phobia of something you shouldn't be scared of, there's normally a situational association. Like if you got lost when you were yo... |
What is this bizarre intersection? | It's called a [diverging diamond interchange]. It's considered one of the best recent innovations in interchange design because of all the [benefits it provides]. > It seems to make interchanging with I-77 easier Yep. That's just one of the benefits. > I imagine that it's super confusing for those unfamiliar with the i... |
In times of severe to hyperinflation, why can't the government mandate a price ceiling to counteract? | Hyperinflation comes almost always because of a specific supply-shock problem. Something has increased uncertainty of the economy so so much that goods do not have any sort of reliable delivery in adequate amounts. Severe uncertainty can come from people hoarding in fear of a war or in fear of supplies cut off. It can ... |
using coffee grounds to filter out lead ions from water. | scientists tested whether or not coffee grounds could be used to filter lead out of water. they found some interesting things out, firstly if more coffee grounds are being used more lead is removed from the water. Secondly neither water temperature nor bean type have any effect on the amount of lead removed. If the cof... |
How do we know life on other planets will be of the same type as life on Earth? | I took a class in college about this actually, it had nothing to do with my major, but you don't pass up the chance to take a college class on aliens. It's been a few years, but from what I can remember, you're right, we don't know that life would be exactly like ours, but based on what we know now, that seems the most... |
Why do I always feel like I need to piss right after I cum? | Because its your body's natural reflex to return your urethra to the proper pH to avoid bacteria growth and also to clean out and residual semen. If you fap, don't pee and go to bed. When you wake up to pee you might notice it splits in two streams, that's cause your piss is being blocked by a little bit of jism |
Why is when my body is freezing (like making snow balls without gloves) and I go and put them under a hot sink they ich like crazy? | When your hands get cold the blood vessels in them contract. When you run them under *hot* water they expand rapidly, stretching them and the area around them, causing discomfort.Don't have the answer to that question, but don't use hot water, use cold water first until your hands have warmed up from freezing to cold, ... |
Why is it worthwhile to separate colors from whites in laundry? | In the past, you would often add bleach to whites to help clean them. However, it would destroy colored dyes, so you would need to separate them first.i believe upon first wash , some of the dyes can run and influence the color of the whites. i don't fucking know. i've only ever seen it in the movies. |
Why does the TSA require a max limit per bottle of liquid/gel but no limit on the number of bottles? | Because the TSA's rules are arbitrary and meaningless.Because one 300 ml cream bomb can take out an airliner, but three 100 ml cream bombs cannot.The reason the liquids rule was implemented in the first place was because they were worried about people bringing liquid explosives on board . Breaking it into smaller bottl... |
Why is the bathroom light switch in hotels outside the door? | It is a precaution so that you don't electrocute yourself trying to turn off or on something with wet hands. In UK,only pull cords are allowed inside bathrooms. Having switches inside bathroom may land you to into legal trouble. |
How do scientists determine the calorie content of a food item? And the nutrient content? | They literally burn it, as far as I can tell. We got to do this in Chemistry with Pringles and a can of water suspended above the burning Pringles. We used a butt load of foil to direct all the hear towards the can. _URL_0_ Edit* My guess is that they use lasers to burn a piece and then measure the heat given off. As f... |
How can people be convicted for offensive statements? | Are you American? I ask because this is really weird for many Americans. In the rest of the world, it's pretty much agreed that inflicting emotional distress through offensive comments should be illegal. There's room for debate about just *how* offensive the comments must be, but it's basically only the USA that doesn'... |
Why does exposing factual information about a company lead to a successful lawsuit against you? | It depends on how that information was obtained and what kind of information you're talking about. If it's not public information, , think of it like insider trading. This information is an asset of the company, and by making it public, you stole this asset of the company. If it's whistleblowing of illegal activities, ... |
Why aren't germicidal ultraviolet lights used everywhere, to prevent the spread of disease? | They use a wavelength of light that is cancer causing. Do you want to sit under a cancer causing light? Plus, they aren't all that effective to stop, say a sneeze from transmitting to another person. It takes some time to kill the germs. |
How is kilogram a unit or mass and not weight? (flair physics) | Mass is a unit of how much "stuff" is in something - if two objects have the same number of particles , then they'll have the same mass, anywhere in the universe. Weight is a little different, because it's actually a unit of force - in most cases, it's the force of gravity we're talking about. And that'll change anywhe... |
Why wouldn't game developers make exact copies of good old games but with better graphics? | Well thats actually something that has been happening a lot in the game industry recently. There have been quite a few remakes / remasters. This year alone we got a re-releases of the last of us, kingdom hearts 2 and 4 Halo games so it's a thing that is happening. I think though that you more asking why don't they just... |
Why are button batteries so expensive? | Very often, miniaturisation *does* make things more expensive. However, I think you might simply be shopping in the wrong place. You can get packs of 20 LR44 button cells for well under $10 - it's a matter of shopping around.Common button cells contain silver or mercury for the cathode reaction. As silver is an expensi... |
Why was America reluctant to join the allies in WWII before Pearl Harbour? | The US was a lot more isolationist back then. Not only that, but they weren't the military powerhouse that they are today. The military might of the US was mostly untested. WWII is really when the US came into the forefront in that arena. It also wasn't that long after WWI; the US wasn't keen on getting themselves into... |
Why don't seizures cause the heart to spasm erratically like other muscles? | Seizures start in the brain and send electrical signals to the muscles. But the heart has its own separate electrical systemOther muscles are under voluntary control; heartbeat is controlled by a signal from the brain which comes down a special nerve, the [vagus nerve]You have a central nervous system and a peripheral ... |
Coughed up a tiny tooth? | Try to break it open. If it's tooth or bone, it'll have a soft interior where the marrow or pulp was. More likely is that it's either a tonsil stone that somehow didn't get stinky, or it's a piece of gravel that got kicked up into her mouth. If you can't break it, it's probably gravel, as a bone or tooth of that size w... |
why does the mentos and diet coke geyser have to be diet coke? | The process is called nucleation. See those bubbles that form on the sides of your glass when you fill it with soda? They're bubbles of carbon dioxide, formed when the tiny cracks and crevices in the glass give them a place to form. A typical mint Menthos candy is covered in millions of microscopic pits, which give the... |
Masturbation, oral sex, and other non-intercourse from an evolutionary perspective | its a way to bond and resolve conflict within groups. like with the bonobos.They do it for the same reasons we do. It's fun. They discover it through experimentation and/or observation. |
How is love any different to being overly-attached? | Love is about wanting what is best for *them.* Being overly attached is all about *you.*To kind of follow up on my other comment differentiating between infatuation and "overly attached", I think the root difference between love and being overly attached is that one is the emotion that one feels, and over attachment is... |
Why do we always think that dreams are real life despite them usually being obscure and unrealistic? | While dreaming, the part of your brain that determines if things are obscure and unrealistic is operating at a diminished capacity. In a sense, you are just not smart enough to realize there is anything wrong with an illogical situation.Same reason why we believe that vivid hallucinations are real . Our brains believe ... |
Why is the Mona Lisa worth so much money? | Think of it this way, little 5-year-old Billy/Sally: you have a really cool toy. All your friends look at that toy and want it. But you hold on to it, because it's special to you. Over the years, far into the future when you grow old, people still look at your toy and wish it was theirs, and think it looks really cool.... |
why is it that big dogs drool alot while small dogs tend not to drool at all? | Larger animals have to work harder to keep cool. Volume, which determines the amount of heat produced, goes up with the cube of the length of the animal but surface area, which determines the rate that heat is lost, goes up with the square. Dogs cool off by panting while producing drool instead of sweating. Large dogs ... |
Why are springy doorstops made with maximum compression? Wouldn't they be more effective if they could be compressed to cushion the door's impact? | The coil is just for flexibility . If the spring was not compressed though when the door was pushed into it the spring would compress, absorbing the impact , however it would the release this compression, flinging the door back towards the person opening it . The more force the door was opened with potentially the fast... |
Why do different people like different climates? | I live in the Las Vegas Valley and chances are if you lived here long enough you grew a tolerance to heat, went to Norwalk and I was FREEZING. After long periods of time we get used to the temperatures in our enviroment, the same way early humans adopted to breathing atmospheric oxygen. |
How is fire able to be on the surface of water? | There's something else on top of the water that is burning, like oil or fuel or flotsam. |
Why are taxes on gasoline a fixed dollar amount when nearly every other tax is a percent of the sale? | The price of oil fluctuates wildly in response to geopolitical events and supply factors that state governments have no control over. Rather than try to budget in advance for such an impossibly unpredictable revenue source many governing bodies opt to impose a tax on volume instead. It's not perfectly predictable eithe... |
Why Do Most Games These Days Indicate Loading With An Icon Instead of a Bar? | One less feature to support. Loading bars are actually pretty hard to do correctly. How much work is left to be done? What percentage of it is done? Keeping track of that adds development overhead to some overworked teams, and usually isn't particularly accurate. Modern game UIs tend to be heavyweight, too. Many of the... |
How does electroplating work? | You stick what you want to electroplate into a pool of metal ions. You then run a current through it . The metal ions will stick to the thing you are electroplating.
