What happens when a ski lift breaks down? How does everyone get off safely? | Well when it happened to me, we just sat there annoyed until it was fixed. But a ski lift is essentially a giant conveyor belt, so there's probably a way to rotate it mechanically without power. |
If all our cells renew themselves every 7 years, why do we appear to age over time? | Because the regrowth is not perfect, the body also needs to grow until its twenties, and because wrinkles are not affected by replacement. A wrinkle is like if you squished a cloth a bunch of times, it would have wrinkles and replacing all the individual threads of the cloth would NOT make the wrinkle go away, because ... |
Why do Dogs have a much shorter life expectancy than humans? | Why Humans Live Longer Than Dogs Being a veterinarian, I had been called to examine a ten-year-old Irish Wolfhound named Belker. The dog's owners, Ron, his wife, Lisa, and their little boy, Shane, were all very attached to Belker and they were hoping for a miracle. I examined Belker and found he was dying of cancer. I ... |
The philosphical point of life | It is your task to design a life of your choice and complete it to the best of your ability. |
How is Judaism a religion and at the same time being a Jew, a race? | Judaism isn’t big on converting non-Jewish people, so the religion never really branched out beyond the ethnic group that started it. For the most part the only people who are Jewish are so because their parents were Jewish and so on and so forth, leaving most Jews being of one common ethnicity. Additionally, inter rel... |
Can windfarms strategically placed in the middle of the USA stop tornadoes? | That is like asking if we put enough pennies on a railway track, could we stop a runaway train or if man had a harry enough chest, could it stop a bullet. There is so much energy in the weather system that anything we have or currently can do would barley be measurable if at all. Short answer, No. Long answer, Nooooooo... |
Being fluent in more than one language, why sometimes you can't remember a word in your native language, but know it in the other(s)? | Imagine a bunch of boxes. Each box is a concept, not the thing itself or the word, but the idea of the thing. When you learn words, you put them into the corresponding boxes. The word "tree" goes into the box for the concept of a plant with a stem and leaves, the word "mother" goes into the box for the cincept of the b... |
Why do companies say "no purchase necessary" when they run contests? | So, in some parts of the United States, contests that require you to purchase something are considered a lottery, and lotteries are legally only allowed to be handled by the state. As such, they need to make it not a lottery, by allowing people to enter by sending a letter to the company instead of buying something. No... |
What happens when both litigants in a lawsuit generally use the same lawyer or firm? | A single firm can't agree to represent both litigants in a lawsuit. When the second person tries to hire them, they have to say "sorry, there's a conflict of interests, you need to find another firm".As NOT a lawyer, that's conflict of interest and they wouldn't be able to handle both cases. There was an episode of the... |
How is comet Oumuamua (C/2017 U1) able to come closer to the sun than most of the planets in our solar system, and escape without going into solar orbit? | It's going fast enough -- higher than *escape velocity* -- for its momentum to overpower gravity's pull. |
Why does sleeping help you get better when you are sick? | When you are sleeping your body is able to put all it's energy into repairing you and healing in any manner. Including fighting stuff off. |
How come when power resetting electronic devices such as a cable box or router, you are instructed to unplug the power and wait about fifteen seconds? why is the wait necessary? | Inside electronic devices there are things caused "capacitors." These devices take in the electricity and help make sure that it is released to the device at a steady stream. Fluctuating power is bad for sensitive electronics. When you pull the plug, or turn the device off, you are giving the capacitor time to empty th... |
The Beatles (John, Paul, George) began by playing guitar and bass. Later songs have John and Paul on piano. Who taught them? | Pauls dad played piano while he was growing up so he picked up some stuff from him. He also took piano lessons in the early 60's. John probably just picked it up over the years, once you know one instrument its a lot easier to learn another especially piano. You can make it sound good without mastering it |
Why is cell phone service non-existent in basements or certain buildings? | Concrete can block cellphone signals. It is thick/dense enough to stop cell phone frequency waves from passing through it. |
How is Zionism antithetical to Judaism? | Some Jews believe that the Jews are not allowed to have a homeland in Israel until the Messiah comes. This is the reason Jews don't believe Christ was the Messiah. The Messiah was supposed to establish a kingdom for the Jews to live in peace and prosperity. But Jesus didn't do that, so they're like "he couldn't have be... |
ELI 5: How does reddit's voting algorithm work? | To explain it like you're actually 5. The posts on the frontpage is shown in order of newest to oldest, however each upvote makes it so a post is treated as newer by a certain amount, which is less and less for each upvote. A downvote is pretty much exactly the opposite of an upvote. |
why are urinals not shaped to prevent splashback? | There are lots of options available that were designed to prevent splash back, they naturally cost more than those that weren't. Because the guy that pays to construct the building doesn't give a crap about your shoes, he buys the cheap ones and places them uncomfortably close to one another. This toilet has a fly stic... |
Why can't we send radioactive waste into space? | It is really expensive, and the risk of failure a bit too high. Rocket blows up in our atmosphere, radioactive waste everywhere!My guest would be either ethics or the cost to accelerate things out of orbit. |
How do graveyards make money or sustain themselves after they are full? | It's pretty complicated and gross. Graves are turned over in some countries. After around 100 years, grave sites lower caskets and bury new bodies over them. In some countries rights are perpetual. _URL_0_ |
How do websites use images or trailers of movies in their articles and reviews if it infringes on copywrite laws? | [Fair use] allows for using copywritten material for "transformative" use. The extent of transformative is debated but generally includes things like parody and criticism without having to ask permission from whomever holds the copyright. It doesn't allow you to use the entire work, just parts that are relevant to what... |
is hearing the last sense a human has before dying? | We don't have clear data on this since it's impossible to interview dead people. For example they may or may not keep a sense of touch, or of internal body sensations, slightly longer. |
Why was Richard Nixon pardoned? | To put it very simply, president Ford said he wanted to put "this long national nightmare behind us" by pardoning Nixon. Basically he didn't want the country to get bogged down in all the trials and endless continuing investigations into Nixon and staff post-WH. However, many Americans wanted to see Nixon and his co-co... |
Why is the spine arched (in the lumbar area) instead of just being straight? | Rigid things crack and break under repeated impact. Flexible things bend, absorb, and stay intact. The bends in your spine work the same way as rubber tires on a car or the shock absorbers on bumps in the road when you're driving. If you had solid wheels and no shock absorbers then your car would absorb all the shocks ... |
Why is being a lawyer drastically different from other professions? | It's not really unique -- doctors of all sorts have to go through a similar process. Basically what it comes down to is that they are jobs that require a great amount of trust from the customers -- doctors and lawyers are both in a position to *really* fuck over their customers without them realizing it. They go to sch... |
What is the importance of the 'Closed Circuit' part of Closed Circuit TV? | It means that the data/stream is kept internally in the system. If the internet goes down, you don't lose your connection, it doesn't require a wireless system that could be interfered with, and hacking requires physically wiring into the system or direct access to the controlling computer. |
Cable TV speed vs. internet video | TV channels are like giving a speech to everyone. You talk once, and everyone hears the same thing. This is **broadcast**. The system is designed to send the same channels to everyone, at the same time, all the time. Your cable box just has to "listen." Internet videos today are like you talking to each person individu... |
Why was James Holmes, the 'Dark Night' movie shooter, declared 'mentally ill' and not 'legally insane' in court ? | Insanity is a legal term, not a psychological term. Insanity is simply an inability to distinguish between right and wrong and an inability to function within our society as a result of mental complications. If a killer knows they shouldn't kill but do it anyway, they understand this difference between right and wrong ... |
Why does everyone use danish cookie containers as sewing containers? | Yeah man, it starts with old ladies being the least wasteful people you will meet. So, they get these old lady cookies from other little old ladies in their social group- then reuse it for sewing stuff since the lid is just the perfect height for the thread spools. The small ones stand upright and the big spools lay on... |
Why do imgur gif's have to slowly load the entire gif while playing, when sites like gfycat can load before playing? | The GIF format was originally designed for looping animation. It's not very good for videos; the normal video compression excludes a lot of information that is redundant between frames, but the GIF format can't do this. So GIF files used to show a video are excessively large and take a long time to load. Gyfcat does no... |
Watts, volts, and amps. | Sorry, but this one is one of the more frequently asked questions here. I highly recommend using the search bar to answer this one. It is being removed for that reason. |
Why does reddit some times hide the scores of comments? | It prevents groupthink. We have a natural tendency to agree with our peers and are impressed by early success. If you see three comments all at +1 and then one comment at +3, you may subconsciously think "the one at +3 must have more merit since it's higher", so you're more likely to upvote it yourself. Hiding scores f... |
Why/how do actors choose their "stage names"? | Many reasons! Some pick their own, some are given one. * Avoiding confusion with someone else, sometimes per Screen Actors Guild rules. There was already a Diane Hall, so Diane Hall became Diane Keaton. * Hiding national/ethnic background, especially in the past. Margarita Cansino didn't want to be stuck with "exotic" ... |
How is the price for commodities such as oil/gold determined? | Supply and demand is what is comes down to. During summer time, when travel is more common, people use more gas/oil. Since the supply is controlled and kept constant, and the demand increases, there is less extra supply to go around. Prices go up, because people are willing to pay more for the access to oil, since they... |
Youtube's copyright policy on music. | If a video of your contains obvious music that belongs to someone else, it *might* get caught by Youtube's filters. Otherwise, Youtube doesn't care, until the intellectual property holder contacts them about your video. At that point the rights owner can choose to put ads on your video, the revenue from which will go t... |
Taurine Manufacturing in energy drinks | You already answered your own question, testicles basically do what we do in the lab, they provide the right temperature, substrate, enzymes required to chemically alter a molecule. From animal sources would be time consuming , and you'd have to add some steps to isolate taurine from the rest of the biological material... |
Why are car model years not displayed on the car itself? | Because people don't want to advertise how old their car is. It would therefore be detrimental to sales. I can tell you that I've seen examples where the model year was incorporated as part of the license plate. People absolutely *hated* it, and complained vehemently until that law was repealed. |
Why is the flow on the discharge side of the fan much faster than on the suction side of a fan. | Its only because the air is concentrated at the discharge. You're pulling in the same volume as discharging. |
What Twitter does with the extra 20 characters | On Twitter, you can have other people's tweets sent to your phone through text message. If the max was 160, you wouldn't be able to tell who sent the tweet because the tweet took up all the characters allowed in a text message. So basically, 20 characters for usernames, 140 for content. |
if I check myself into a mental hospital, who takes care of the things like my job, my property, my bills, etc? | It's correct that you would need to make arrangements on your own or arrange for them to be arranged -- which really sucks because that's pretty freaking difficult to do when you're experiencing that kind of crisis. A few notes: - Your employer may offer something that in the states is called an Employee Assistance Pro... |
. What is a quantum computer and what are the applications. | A quantum computer is like a normal computer, but instead of using 'bit's that can be either 0 or 1/on or off, they use a quantum mechanical object that can be both at the same time in a process called superposition. The object is called a quantum bit, or qubit. The effect of this is to be able to, in essence, run mult... |
Why are street lights clear and bright white when they turn on, but then turn into that orange color we are all so familiar with? | Orange streetlamps are low-pressure [sodium-vapor lamps]. The clearer, pinker/whiter glow when it first turns on is the lamp heating the solid sodium inside. As the lamp heats up, the sodium vaporizes. The sodium vapor is what gives off the orange-ish light. Sodium vapor lamps are extremely energy-efficient, and they d... |
Since nose hairs act as a filter for germs and bacteria, when you trim your nose hairs are you more susceptible to illnesses? | The relatively large hairs in the nose don't do much for bacteria and viruses. The large ones might be helpful for dust etc. but I'm not 100% on that. The 'hairs' that are important for protection against bacteria and viruses are the microscopic hairs , which line the rest of the respiratory tract. Smoking and other co... |
Why do Sport drinks like Gatorade hydrate you with that much sodium in it? | The purpose of Gatorade is not to rehydrate you . It's main purpose is restore electrolyte balances . Professional atheletes sweat excessively, and when they do they lose both water and salt. Drinking just water doesn't replace the salts, Gatorade does. |
Why do I sometimes get the feeling of a splash of water dripping on me when really there's nothing there? | There is something there. Me. Flicking water. At you. And you'll never catch me. |
How are those scary clown pranks not illegal? | I didn't watch the entire video. I just scanned it. We're they dressed as clowns when they "impersonate policemen"? If so that's not a crime. Since no police officer would wear clown make up on the job. So it's clearly not a police officer. However if not then it's a crime. It's not illegal to dress as a clown and scar... |
Why are there still so many electronics devices like printers that give cryptic error codes instead of just a plain English explanation of what's wrong? | Two things, the first is complexity, devices with a tiny 16 character display really don't have much of an option to display a full error message and might not have the capability to store that text internally , error codes are a simple way to give the user a very condensed description, where they can look it up. Secon... |
why do browsers have to put from where did you acces to that website: (utm_source=chrome-ntp-icon)? | It's google analytics tracking code. The site you are visiting wants to track the source of the traffic. either that or you clicked on a link that uses this code - more common in newsletters tho. |
Why do we wake up if we are falling in our dream? | The jolt of adrenaline that rushes through our body wakes us up. Falling or dying feels very real, and our brains and emotions work overtime. *It's that feeling of falling you get that jolts you awake. It snaps you out of a dream.* The "Kick". Most times, it feels like Inception. That feeling of falling or near death e... |
Does someone with stronger, bigger muscles have a greater resistance to pain than a skinny, scrawny person? | The 220 would be vastly more prone to injury and pain in this example due to weight. Imagine if at 110 he landed feet first with just an ankle sprain. Now add another 110 pounds and maybe that's a fractured tibia. In some examples, like when people take cannon balls to the gut, sure strong muscles are why they can do t... |
Why do political parties try to be opposites of each other instead of working together to solve problems? | It's much harder to get elected that way. If I'm running for office and you're not sure if you should vote for me, which sounds more convincing: "Hey, vote for me or the other guy, we'll each tackle these problems in our own way and arrive at a reasonable solution." "That other guy stands for everything you oppose and ... |
How speeding was enforced before radar guns | Two lines were painted on the road at a measured distance and police would check the amount of time it took to pass both lines. Using that information they could figure out your speed. They would also get behind cars and pace them with their own speedometersIn South Africa, the police listen to the time in between the ... |
After a few deep breaths of cold air, why are my lungs so sensitive? | The purpose of your upper respiratory tract is to warm and moisturize air before it gets to your lungs because the cells lining the inside of the lungs are very sensitive to these conditions. If you're breathing really cold air then there isn't time for it to reach ideal temperatures, and it can irritate or damage the ... |
How come 100% humidity doesn't mean that water takes up all of the air and we arent walking in swimming pools. | 100% humidity doesn't mean the air is entirely water. It means that there is as much water vapor dissolved into the air as it will hold. Basically, it's the point where if you left a glass of water out no more of it would evaporate.100% humidity means the air is saturated with as much water as it can hold in vapor form... |
how do telescope cameras take long-exposure photos of extremely far away things? Wouldn't the rotation of the earth/ earth' orbit screw up the focus of the picture? | The aim of the telescopes is adjusted in real time to match the rotation of the planet, using electric motorsMost telescopes have a computer and motor for this purpose. You need to align the telescope first based position of the telescope and time and when that is complete you can basically tell the computer the coordi... |
Does Earth's core really keep on rotating? Why? | Earth's core rotates for the same reason the rest of Earth rotates, which is because of retained rotational momentum from its original formation. Also, if you heard about it from the movie The Core you should probably just forget it. That movie is horrendous from a scientific standpoint. |
String Theory, why people like and don't agree with it | I won't get into trying to explain String Theory in five-year-old terms. That's probably better suited for someone else. But I can probably help with the second part of your question - Why some people like it - String theory aims to solve one of the biggest problems facing particle physics - how to reconcile quantum gr... |
How can the tone knobs on a guitar amp change the way a single frequency sounds | No. When you play a note on a guitar you are playing SO much more than one frequency. You are playing a FUNDAMENTAL frequency plus lots of quieter frequencies called "harmonics" or "overtones." The amplitudes of these frequencies are one of the main factors in determining that your guitar *actually sounds like a guitar... |
The difference between The Patriot Act and the Prism program. | The Patriot act is a bill that grants additional rights to congress and the president. The Prism program is a bunch of things the NSA seems to be able to do under that bill. Maybe. Some people think they have done illegal things, but plenty of people think it's a natural outcome of the patriot act.Prism is simply the N... |
Why would the Cleveland kidnapper plead not guilty when their is so much evidence against him? | Sometimes people plead not guilty by reasons of insanity. By that I mean he may attempt to argue he shouldn't be punished because he didn't have control of his actions. That seems pretty unlikely due to how normal he seemed most of the times, but it is an option that's used in situations like this. He also doesn't real... |
Why was getting dizzy fun as a kid but makes me sick as an adult? | Things that are new can be fascinating but once the excitement wears off, you know how much of an annoyance something likedizziness can beSame thing with drinking, everything is fun when you first try it. |
- What did the Glass-Steagall act do exactly, and why did its repeal contribute to the recession? | I think that "The Newsroom" did a really good EL5 year old job. [Olivia Munn]Basically it allowed for 2 different kind of banks to become one kind of bank. That one kind of bank had the ability to make riskier investments with money that is supposed to be relatively secure. |
The strange jolt euphoria you occasionally get when certain things happen (Friday afternoon, driving through nice weather, etc.) | When things happen, i.e. Friday afternoon after work, this is perceived as a reward due to culture . So, this perceived good activates the brain to release dopamine. Dopamine is a compound, a neurotransmitter, that acts as a messenger. This messenger activates the reward system, which reinforces the connection between ... |
Why are there no hooved predators? | Soft padded paws are a feature of most mammalian predators because it provides for stealth when hunting. Hoves do not offer the advantage of this adaptation. But do not think that hooved creatures are not dangerous-they will fuck you up. A bison will clean your clock and trample you to death. A wild boar will chase you... |
How do internet providers make the internet they sell? | They don't. ISPs give you **access** to the internet by running wiring between your house/apartment to a CO . The CO serves as a hub for traffic, allowing lots of small connections to be joined and sent through larger connections . All these connections allow you to contact different people or servers . To get to serve... |
How can bugs fly in through the smallest crack in a window, but can't leave through an open door? (Or choose not to?) | Well, it's the one bug out of thousands that made it into your house by accident, but only one out of one that you want to get out as quick as possible. ;-)", 'They follow smells coming out from your house through the cracks. Once inside, there are no strong enough outside smells that can lead them outBugs that make it... |
In the United States you can serve in the military at age 18, but you need to be 21 to consume alcohol. Why is that? | The more we learn about brain development the more we understand that a young person's mental development isn't finished until at least their early 20's . It is fair to say that we probably cannot assess risks clearly when we are 18 - so you are right to raise the point - we should probably raise the enlistment age to ... |
Why do a lot of government entities and other companies insist on using Internet Explorer over other browsers such as Chrome or Firefox saying that IE is more secure? Is there any truth to this? | Usually requiring IE isn't by choice. in my experience it is typically because the business have spent a ton of money on an IT system that depends on some IE specific feature, like ActiveX for example. In many cases the business might even have two browsers installed on all their systems, one for their expensive legacy... |
Why can't you scream loud enough to hurt your own ears? | Generally, nobody can scream loud enough to hurt your ears. There simply isn't enough power generated by your lungs in a single scream to do it. Sound is merely a type of pressure wave that your ear is able to sense, decode and turn it into something you understand. Sound is measured through a scale measured in somethi... |
why can i be tired all day long, only to get home and into bed but then suddenly be wide awake when i lay down? | I know this pain I am usually up till 3am :(', "Because your body is exhausted and when you finally lie down, the body gets it's rest and the head is free to think about anything it wants |
Why can't/wouldn't a medical dispensary be able to switch freely to become a recreational one? | Supply and demand and you need to put together a whole board of regulators and you need to grow a shit ton of weed. Also why would you want to take away the cannabis that the medical people need when you just wanna smoke a jay for recreational purposes.The same reason a pharmacy can't just become a bar. The laws, once ... |
How does the popcorn button on the microwave work? | I recently protested the popcorn button against my girlfriend and my mother's wishes. I set the timer to the recommended time on the bag and burnt the shit out of the last bag. |
What is happening during the time a beverage is being aged? | It really depends on the beverage. There are actually multiple different methods. For the most part, that means keeping it in a wood cask/barrel in a cool, dark, dry place for a long time. However, sometimes it is just kept in it's own bottle instead and aged that way. For example, some types of beer are brewed to get ... |
How can vision decrease unequally in our eyes? | What you are referring to is termed [Anisometropia]. The reasons for it are poorly understood, but there is some [evidence that one's dominant eye is often the one which needs more "correction," or has more refractive errors] than the non-dominant eye. [The Miles Test] is a simple, easy test to self-administer to deter... |
NSFW] I'm currently in the hospital attached to an oxygen monitor and an EKG. What will happen if I masturbate? | They'd probably notice your pulse going up. But it's not gonna be like OH SHIT HE'S GOING INTO ORGASMIC ARREST or anything, if that's what you're asking.Keep your pulse under 100/min. Depending on machine, it may go crazy after you go over 120. They ARE watching your monitor thoughReally what do you do if you are in th... |
What is the definition of a lack of empathy? | The inability to understand someone else’s emotions and feelings from their perspective. Eg, if you were obese and I called you fat and it hurt your feelings. If I lacked empathy I genuinely wouldn’t understand why it upset you. Which is different from me understanding why it would upset you and calling you fat anyway. |
Why was NASA based in Houston, Texas rather than any other of the 49 states of America? | The site required access to water transportation by large barges, a moderate climate, availability of all-weather commercial jet service, a well established industrial complex with supporting technical facilities and labor, close proximity to a culturally attractive community in the vicinity of an institution of higher... |
Why is horse racing such a tossup? | They are set up that way. Track stewards assign weights to horses to even out the odds. A very good horse must carry more weight. The less weight the faster the horse runs. More weight also means more injuries. The horse's trainer weighs all of these factors when choosing what races to enter. The goal is to win every r... |
What's the difference between .com, .net, etc? | These .com, .net etc are top-level domains. In the beginning, the different top-level domains were used for different groups of people: COMmercial entities. US-based EDUcation. NETwork prodivders. US-base GOVernment. Not for profit ORGanistaion. US-based MILitary machines. INTernational organisations. And that was enou... |
how is it that waterfalls freeze while falling? | It's not the entire waterfall that freezes. It's a little at a time. The rocks below it, where water sits for a few moments, get cold enough and the water freezes. The water dripping from the top gets cold enough as well, and a little bit of water freezes there. Anywhere along the entire length where water sits for a m... |
What is the difference between a brownout and a blackout? | In a brownout, there's not enough power to maintain normal usage levels, but it's not completely off. You generally see things like flickering / dimming lights, reduced power to buildings, surge protectors going nuts, that sort of thing. In a blackout, the power goes completely dead. E: Wow, that was unexpected, but ve... |
How did no one notice that tens of millions of cars were not meeting their emissions standards until now? | They were meeting their emission standards. That's the whole scam. I assume you're asking about the VW situation going on now. The software that runs in the computer that controls the engine and emission control systems was written to detect when the emission tests were being performed and *only while the tests were be... |
Why do we say 'Boo!' when trying to scare someone? | The B is [plosive], which is a sudden sound - and that suddenness is potentially more surprising. And compared to a few other plosives , it's easy to say loudly - and that sudden and unexpected loudness will more likely shock and scare someone, in the same way that a sudden, unexpected, and loud bang or crashing sound ... |
I am constantly hearing about how adrenaline allows people to complete incredible physical feats. So why is it that I've never heard of adrenaline being abused in sports? | If you give someone a straight shot of adrenaline, you would immediately notice it. They would not be able to sit still. Adrenaline is typically used only in serious medical conditions, often emergencies, like heart stoppage. These factors make it difficult to abuse for sports, and it can put a dangerous strain on your... |
how my phone captured this picture right as it was dying and made it look like this | The interesting thing about that image is that it's two versions of the same photo -- were you taking an HDR photo? You have two different exposure settings, one slightly underexposed and one slightly overexposed. The software then combines the two images for a large dynamic range: the slightly overexposed version ensu... |
At what point did organisms become gendered? | The 'when' question was already answered, do I'll answer the one about the benefits. It allows for greater genetic diversity. When you reproduce asexually, the offspring only receives your DNA making it more likely to get sick . When you reproduce sexually, the chance of a genetic defect is much lower. I have no idea w... |
If everyone I know hates pop music, how does it get so popular? | You tend to hang out with people who share views similar to your own so your sample is skewed. Either that or you don't know enough people. ;)", 'Well,everyone I know voted for John Kerry in 2004 and look what happened. Everyone you know does not equal the majority of the buying publicEveryone you know != everyone in t... |
What determines the power of an engine? | HP is unsurprisingly a unit of power which is the amount of energy delivered over a time. So when comparing two different engines you would pick one time period that is the same for both engines and measure how much energy over the time period the engine produces. |hey, let's make an engine with EXACTLY 218HP" or do th... |
what (specifically) would happen to a house-sized treehouse as the tree grew? Would it be possible to live safely for many years (20+) in a large treehouse? | Trees can grow quite big. A few species ) are big enough to support a house. There are more risks than structure tho. You would have to take great care of the tree so it stays healthy If you started with a small tree, it would likely split whatever bindings you used to keep your house in place as it grew to its mature ... |
If flushing the toilet wastes a lot of water, why don't we pee in the sink? | My brother-in-law is a builder. A few months after one of his jobs he was accused of installing a faulty sink. It was not draining properly. On investigation it turned out that the husband had been habitually pissing in the bathroom sink and had blocked the pipe with crusty pissy mineral build up. Don't habitually pee ... |
Why are most circuit boards green? | It's the natural color of the epoxy. No other reason, really, and since no one spends a lot of time looking at them, they don't dye them unless requested by the buyer. |
Why are VR games so much more difficult to make and why do they require so much more processing power? | > Is having those two corresponding viewpoints active simultaneously much different than split-screen on a FPS where each player has a different view? Not hugely different in principle but significantly in execution. First, your average console peasant is used to their game being presented at about 30 fps and somewhat ... |
Why does the IRS send tax return checks to people when there is so much fraud? Isn't there a more secure way? | You have it backwards. The IRS does allow direct deposit of refunds. And most of the return fraud that happens is through direct deposit, not through physical paper checks. Now if they sent it to the employer, that could help cut down on fraud somewhat, but the fraudsters would just claim to be self employed and so not... |
Why does every material tell me its origins (ex: Made in China) and why do I give a shit? | The easy answer is that it's US Law to name where the product is from. We don't trade with certain countries so if a product says it's from some country we don't trade with, it could be a counterfeit/illegal. Also from the countries perspective, they obviously want people to know where it came from for obvious reasons.... |
Why do all men and women in old radio/tv recordings have "that" voice? | The neutral radio voice was a requirement in Hollywood for along time in order to not alienate some audiences. I speak neutral English and can get a job on any radio station in the US.

Tesla's Dynamic Theory of Gravity | No one has a damn clue what Tesla was talking about. He died before publishing anything, and his notes were never made public after the US government confiscated his belongings after his death. Not much more to it than that. We do know that he thought Einstein was fundamentally wrong, his statements on the subject show... |
