why musicians on youtube need to wear headphones while they record but live musicians don't | Live musicians use stage or in-ear monitors which do basically the same thing - allow them to hear themselves.Live musicians often also have ear monitors. They're just not as noticeable. |
Why are test scores so crucial in schooling? | we need a way to assess kids in a way that is as neutral as possible. Higher grade says a lot about your work ethics, motivation, ability to follow instructions etc.It is not a simple assessment of your intellgience. it is an objective way the adults look at you and your potential. although more people are realising gr... |
What is the difference between Android and iOS regarding how both operating systems work? | It's a very broad topic, but to answer your specific question, > I just heard that iOS is somewhat a closed system in itself and Android isn't. But then again I don't even know what that means either. Basically, this boils down to the fact that the only way to make and publish an application for iOS is to submit it to ... |
What happens to my $15/hr job if the minimum wage is increased to $15? | Companies have no obligation to increase your pay, so you'll probably see no immediate change.That being said, over the course of a few months, depending on the company, you might see an increase, so that they can keep workers/~~higher~~ hire new workers. |
Why does it take 20 minutes for my stomach to tell my brain that it's full, when messages from my nervous system travel thousands of miles/kilometers per second? | When you eat, the sugar level in your bloodstream rises. This is in by muscle and fat cells as energy. When the fat cells get the energy, they release leptin which your brain recognises and tells you that you are full, and you can spend energy. While this process takes some time, it also has the added benefit of being ... |
Why is so much land only just above sea level? | Well, the mean elevation worldwide is something over 800 meters. But, a large percentage of the human population lives near sea level, for reasons of food and commerceThis is a spectacularly good question. I think there's no definitively good answer. The sea level does change. During Ice Ages, it's several hundred mete... |
Why does regular Panadol exist when Panadol Rapid works 2x as fast? | It doesn't work 2x as fast. its an advertising lie. _URL_0_ “It doesn’t make a huge amount of difference at a clinical level,” Dr Kyle told _URL_1_.For the Americans here they are talking about Tylenol. I have never heard of a "rapid" formula, but it appears to be something that is being marketed in Australia and New Z... |
Do the same species of animals have different accents if they are in different places in the world? | Yes, animals do have regional accents. It has been *"proven"* for various animals like cows, goats, parrots, dogs and whales. For example, cows in different herds will moo at a different pitch. Not only do they have different sounds, outsider cows who are introduced in a new herd will by time moo the new moo. Another e... |
what happens if a lactose intolerant person chugs/eats A LOT of dairy? | Lactose intolerance is essentially a severe deficiency in the enzyme lactase, which breaks lactose down into digestible sugars . Humans at some point started drinking milk well past infancy, and eventually evolved the ability to continue expressing lactase throughout their lives . However, there still remain some peopl... |
Why do different areas of the U.S. have such dramatically different "accents"? | Because, when people started moving to America, they weren't all from the same countries. People living in different places had different ways of talking to each other. When they came to American, all their different ways of talking blended, like the dinner on your plate. A lot didn't mix, but some did. When you look a... |
Why do people always land a perfect high five when looking at the other person's elbow | The elbow stays relatively fixed and can accurately predict where the hand will be when you strike. Extrapolating the position of the hand based on it's movement around the elbow-axis is relatively harder, when using the moving hand as the input info. That said, there is a lot of bias in this theory since most of the t... |
How does HBO use so many brand names and products? | HBO has it easier because they don't have commercials in a show. One of the biggest reasons regular TV blurs out brand names is for future advertising. If your TV show always shows people drinking Coca Cola, you're guaranteeing that your show will never have Pepsi as a sponsor after it's in Syndication and Re-runs. HBO... |
Why do they let the Juno probe crash on jupiter after the mission? | There is no possible alignment of the planets that would enable Juno to escape Jupiter's gravity. And if it did return somehow to Earth, it would burn up in the atmosphere. It isn't designed for atmospheric reentry, as those features would make it heavier. |
What exactly happens in your brain when your reflexes "kick in"? | I think OP means like intentional no intentional actions. Such as avoiding a threat from a visual stimuli, not the mechanics of basic reflex. |
Why are precious metals, uh, precious, within the context of a world economic collapse? What good would having gold and silver without rule of law? | Because people would believe they were valuable. Throughout history, people have figured out that barter is a pain, so they have taken some arbitrary, largely valueless item, and giving it artificial value. It has to be rare enough people don't just dig it up, but not so rare there isn't enough of it to go around. It h... |
What is the difference between 87,89,91 | The octane rating deals with how easily a fuel ignites, with higher numbers being more resistant to igniting. For higher-end sports cars, this is important because their engines typically create significantly higher pressure before combustion to harness more power. If the fuel ignites prematurely the fuel can ignite be... |
Why are so many people allergic to Gluten? | Many people are jumping on an anti-gluten bandwagon -- they're uninformed, and think that it's bad for them, or that their one symptom in common with true gluten sensitivity is actually indicative of a real gluten problem. A headache is a symptom of a cold or a brain tumor -- you're more likely to have a cold . Regardi... |
Why does cheese taste so much better when melted and browned? | One reason, as /u/snigglesnort mentioned, is texture. It becomes creamy when molten and crispy when browned. Also a lot of food tastes better when warm because you can smell it better and every "taste" that isn't "sweet |
Why does taking vitamins on an empty stomach cause an upset stomach? | Vitamins are a little often-hard pellet of one or more various compounds, some of which are acids depending on the type you're taking. When you swallow that pill whole without anything else buffering it down there, it basically sits on your stomach lining, sometimes reacting with or penetrating its protective lining an... |
Why are websites promoting crazed use of infinite scrolling? | The most common time for someone to leave your website is when the page ends. So if the page never ends, the theory goes, you're less likely to leave. |
Why does the weight we gain from food based off of the food's calorie value instead of its physical weight? | The parts of food that don't contain calories aren't absorbed by our bodies and come out as urine and feces.So imagine the difference between, say, gunpowder and C4. Both are explosive, but C4 is a lot *more* explosive. There's more energy stored in the molecular structure of C4 than there is in gunpowder. So that's th... |
Why does a higher fps mean slower footage on a Slow Motion Camera, when in Videogames, it means faster? | Higher FPS doesn't mean slower footage. Time passes at the speed time passes. However, if you want to shoot slow-motion stuff, you need to shoot with a higher framerate or else the camera is not recording enough data for it to look good when you slow it down. Slow-motion stuff is shot at high framerates. It still recor... |
Why is having some fat on our bodies beneficial for us when were sick? | I'm not exactly sure of the complete reason but a part of it has to do with the fact that we use fat to get energy. When you're sick, your body needs to increase its energy use to be able to overcome the sickness. For example, If you have the flu, your body increases its temperature to destroy the viruses in your body,... |
Why does road-rage make people behave the way they do? | I had heard that it was related to people's personal space. Some people, those more inclined to road rage, viewed the vehicle as being their personal space. That means when other cars "wrong" them, they see it as a personnel attack rather than an incident on the road. I had read a study that talked about people who had... |
How would the global economy grow if we returned to the gold standard? | This isn't quite as huge a problem as you make out. With a fixed supply of money prices would simply fall as the total amount being bought and sold increases. . During the 19th century, most currencies were tied to the value of gold and they had periods of both deflation and inflation as well as considerable economic g... |
How are illegal immigrants able to afford to come to the U.S., support themselves and send money back home while so many citizens are dependent on government assistance? | It's a combination of working their asses off and also living as cheaply as possible, which is why you hear the stereotype of an illegal family of 30 people living in a one-bedroom apartment. A "living wage" becomes much lower if you make your idea of "living" much cheaperwork ethic, they'll work any job necessary to s... |
Why after running for a while do my lungs get that painful burning sensation? | I'm surprised no one's given this answer yet, so here goes: Congratulations! You're using a lot more of your lungs than you used to. While you're running, you're building up an oxygen debt as your muscles start to use more and more oxygen than you've asked them to in the past, and your lungs are struggling to keep up. ... |
Why did some old programming languages like PL/I and "real" BASIC completely die out, while some like Fortran and COBOL never get replaced? | The rise of Unix brought C and C++ to the fore, and these replaced many languages. Fortran and COBOL have been on the decline for a long time. They stay alive because of large code bases that would be expensive to port to a new language. |
How did 209 countries attempt to qualify for the 2014 FIFA World Cup if there are only 195 countries in the world? | There's a lot of "countries" in the World Cup that other governments don't recongnize such as Palestine. There are also multiple teams in one country like England and Wales each have their own teamAnguilla, Bermuda, Aruba, the British Virgin Islands, the US Virgin Islands, the Cayman Islands, Curacao, Montserrat, Puert... |
Why are Carlights in the distance still very blinding even if they have no visible impact on the surroundings. | They produce a narrow cone of light using focusing optics, since most people only want to see what they're pointing at/where their car is driving towards. It would take *a lot* more power to illuminate a wider cone equally well. Now, I'm going to hazard a wild generalization, and inform you that American cars suck badl... |
how does 'flipping' houses work? | It can be a scam. It can be a hobby for some people. Ideally you buy a house that's an ugly/old house on a nice block and renovate it. This is a bit of a gamble because you'd want to buy a house in a new or upcoming neighborhood so the property value will increase over the course of the renovations. Just to make it eas... |
How did early people give birth to children without proper tools and sanitation? | Tools aren't generally required. Babies have got quite a bit bigger as people have got better fed, so years ago they were a bit easier to squeeze out. Sadly though, the most important thing is that lots of mums and babies died. Infant mortality was high, and things like puerperal fever killed a lot shortly after birth. |
Recently, a man tripped and punched a hole in a 1.5MM painting. How is the value determined, and why is it so high? | I 'd like to try and answer this, but source would be nice. Namely a painting name, but a news article would be better. Generally value of paintings is determined by these things : * Is it authentic/the original. This is pretty obvious, the real one is worth more than a fake one.* Who painted it, and how popular/trendy... |
If there were bacteria on Mars, why wouldn't it be everywhere like on Earth? | Mars lacks a functional magnetosphere to protect the planet's surface from the Sun's radiation, and the atmosphere is incredibly thin and diminishing more every day. As a result there are very few locations on Mars where bacterial life could live for a prolonged period of time. To put this in perspective, even after a ... |
If I'm moving at 100 mph and throw a ball forward at 100 mph does that ball now travel at 200 mph? | Relative to the ground yes, provided you throw it in the direction you are moving. Relative to you no, it is traveling at 100mph. Relative to the sun it's probably closer to 67000mph |
How did so many people end up left behind by the decline of the coal industry? | It was a self fulfilling destruction. Coal jobs paid pretty good. Right out of high school you could start out making very decent money, or try to go off to college and do something else, where after 4 years in school you'd start out making less than your buddies back at the mine. My own father works a brutally physica... |
Why do the majority of automatic guns have 30 bullets in their magazines? | Military clips come with 10 rounds a piece. A magazine using them is best off loading in multiples of 10 rounds. So you're looking at choosing between 20, 30, or 40 rounds. 40 is just too much for standard use. It makes the magazine stick down too far to shoot from prone , and it makes the rifle too heavy . 30 rounds i... |
Why do you see prismatic light when wearing polarized sunglasses and look through a tinted window? | Light initially hits the tinted layer of the glass which only lets through light that wobbles in one direction . The light then continues on in to the non-tinted glass which has a property called birefringence. The important thing to know about that fancy word is that the glass will change the direction that the light ... |
Why is CNN so upset over the wrestling gif and not directing their anger at the president when he retweeted it himself? | Because there is a new goal with this one. They want to stifle any kind of negative CNN comment or posts. It's sad as fuck and it clearly shows that they are scrambling to maintain any perceived legitimacy they think they have left. Spoiler: They have zero legitimacy or ethical acumen. Every single person I have spoken... |
How can water stay in liquid form even below 0C/32F? | Temperature isn't the only variable that determines the state of some substance. Pressure also plays a vital role. However, in our day to day life the ambient pressure won't vary by very much. At our normal pressure, water *always* freezes at 0C. So how do we get water to stay liquid below 0 degrees? We have to mess wi... |
why do basketball games look slower on tv then they do in person? | I don't think they look any slower, but rather the camera view that most games are shot from is the ideal angle where you can see the entire half court and every player moving. You can therefore anticipate where players are going to be and cannot see their subtle quick movements as well. If you were to sit at a live ga... |
How does Steam Guard Mobile Authenticator work even if your phone has no internet connection? | It's difficult to know exactly steam's implementation since they don't expose much information about how it works, but it's likely similar to other Authenticator apps like you use with Google / Dropbox / Hotmail / Blizzard, etc. Effectively what happens with the types of authenticators I mentioned is that the server pi... |
How do scientists come up with names of drugs such as diphenhydramine and benzodiazepine? | The funny looking syllables denote functional groups in the chemical structures of the drugs. The naming of functional groups have sometimes logical reasons, for example decane denotes a ten carbon alkane some of the namings are completely arbitrary, as /u/Opthalmology mentioned. IUPAC has a standardized nomenclature f... |
Why would anyone make estimated quarterly income tax payments? | If you run a small business from your house, or you are a smaller scale giging musician, then there is no withholding. The government doesn't like that, so they fine you if you don't make payments. |
Why is Judge an elected position? | Perhaps not the answer you're looking for, but electing judges is an almost uniquely American habit. Much of the rest of the world performs judicial appointments via the legislature or executive, or from within the judiciary itself. Seems to be working out fine for us so far.Perhaps to help avoid overt corruption? If t... |
Why it's harder to breathe during strong winds | When air move around an object it usually creates differences in pressure. Much like a plane wing. Now imagine a strong wind moving past your mouth. This will generate a low pressure in your mouth. This will now feel like it’s harder to breathe because there will physically be less air in your mouth.Do you know when yo... |
How did the first ever translation between two different languages come about? | Likely the same way you would learn a new language if you were thrust into a foreign country. You would find common necessary objects and learn those names and expand your vocabulary over time. With enough vocabulary you can start getting context and syntax clues to be able to piece together your own sentences in the n... |
What is the difference between a SSD and a HDD? | The short and sweet version is, a hard disk drive uses a spinning disk to store the data, which is read by a special sensor on the tip of an arm. It works the same as a record player, just on a smaller and faster scale. Solid state drives use flash memory, similar to the SD card that phones and other devices use. Solid... |
If the entire world uses either 110V or 220V, why there are so many kinds of power plugs? | Power plugs were developed independently by different countries at around the same time. There was never a globalized standard set at the time, and even though people travel around the world now, it would be too expensive to change all the plugs.They were all designed before travel and portability became important. For... |
How does the Pirate Bay keep maintaining a well known easy to type DNS address? | Well, you mainly need to understand the politics of domain names and ICANN. ICANN, or the Internet Corporation for Assigned Names and Numbers, is the organization that oversees the internet in general through two primary tasks, IP address allocation to ISPS, and DNS. They "oversee" DNS in a bit of a weird way, here is ... |
How is it my 8 year old can pick up and learn to play music, but I a grown man of 38 have absolutely no comprehension. | Kids brains are much more elastic than adults and they can pick up things very fast with the right motivation. For instance, in Viet Nam they put them in a basement and tell them no rice until they've made 40 pairs of shoes. Makes them learn incredibly fast. |
Why do we have different cups for different drinks? Wine Glasses for Wine, Coffee Mugs for Coffee, etc | The aromatic compounds of alcohol are intensified depending on the shape of the glass. So a brandy smells better in a snifter/large goblet, and wine in a wine glass. Champagne glasses direct the bubbles to the nose. Shot glasses are for rapid drinking and convenient measurements. Soda/water glasses are for volume drink... |
why does FaceTime Audio call sound so much clearer than regular calling? | FaceTime audio uses data, which has a higher bitrate than a regular call. More bits = more information = better quality :)', "Human hearing extends from 20 Hz to around 20,000 Hz. If you communicate over telephone networks, the high quality sound is limited from 150 Hz to 4,000 Hz. In addition, there is lots of noise b... |
What makes it so difficult to cure paralysis? | Nerves do not regenerate the way other cells do. Nerves when cut quickly close themselves off to the matrix outside of the cell, and can grow back a little bit, but we don't see nerves re-fusing together frequently. If we are able to manipulate the severed nerves to join together and the functionality stays the same we... |
Which parties are currently making money from the conflict with Russia, and who are likely to make most from an all out war? | I'm just submitting this opinion piece - not because I stand behind it , but because it's another point of view. _URL_4_ Fact is [the US is a big oil producer now]. And [at least some try to push for exports]. While there are articles trying to refute that the US will become an exporter of *oil* it seems that this is m... |
What would happen to a lawyer if they defended somebody that they knew was guilty of the crime? | They 'd have done their job. That is what they are *supposed* to do. They're not allowed to lie in court of course, but they can absolutely defend their client even though the client is actually guilty. They can present mitigating circumstances, they can argue for acquittal due to various technicalities . > Then the la... |
Could the U.S military (or someone with a boatload of money), technically just upscale those R/C toy robot dinosaurs to create their own 'Metal Gear' programme? | Theoretically, but why would they? Metal Gear would be a bit pointless in reality.It wouldn't really be upscaling an R/C device. The larger the end product will be, the greater the stresses involved at all points of operation. Something the size of metal gear would mean the only thing taken from the original R/C design... |
What do US senators and congressmen/women actually do all day? | Former Capitol hill photographer here! Members of Congress serve populations ranging from several hundred thousand to several million, so they need lots of people to keep track and organize stuff. Members typically are engaged in one of the following: 1. Constituent meetings - this is lobbying, both from corporations a... |
Why can't we use vacuums for buoyancy? | > Wouldn't a space with no material in it have a much lower density? It would! The problem is the materials we have that could support such a vacuum chamber without it crushing are too heavy for the displacement of the vacuum. If we somehow had a magical material which wouldn't collapse under the pressure but was light... |
Is 3D printing the exact replica of a copyrighted item illegal? | Yes. Copying a copyrighted item is illegal, no matter how you do it. That's what "copyright" meansGenerally there is a fair use doctrine. I do not do copyright details. But if you are copying something you own and do not sell it then you are okay. If you go into commercial production of the item, or if you are using it... |
How can we compare two different ratings? | There's no way to know for sure. However, a low number of ratings is probably highly *variable*. That is, if you randomly sample people and ask them to rate the business, there's a larger chance that you'll "just happen" to ask the only two people who think it's a 5-star business if you are only asking ten people - and... |
Difference between kingdom, empire, and dynasty | A dynasty is a line of rulers descended from one family. An empire is a territory ruled by an emperor or empress that may contain one or more kingdoms. A kingdom is a territory ruled by a king that may contain one or more smaller constituent political entitiesA kingdom is a geographically centralized state ruled by a k... |
Why is the Christmas hype starting earlier every year? | Yes, it's all about marketing. Some retail businesses don't turn a profit at all without the Christmas shopping season. Moving everything up earlier extends the number of days that consumers will have to 'get in the spirit' of it all, and leads to more sales.Consumerism. The earlier Christmas season starts, the sooner ... |
how can hot water freeze faster then cold water ? | This is known as the [Mpemba effect] and currently has no solid explanation. Personally, I think it is that the hot water evaporates more than cold water - thus, less hot water exists than cold water when trying to freeze it, and as such the freezing is quicker.As most everyone has said, it hasn't been explained yet, b... |
Is there any reason why, in a car, the acceleration pedal is vertical while the brake pedal is horizontal | It makes the brake pedal wider than the accelerator so that if you hit one by mistake, it's more likely to be the brake than the accelerator. It's a safety thing.If you need to press the brakes really hard you can get both feet on a wide brake pedal. A gas pedal is designed to be held half down for hours at a time. |
How did sheep evolve to have wool if they can't remove it themselves? | We evolved them that way. [This is what a normal wild sheep looks like.] Wooly, but not ridiculously wooly. It would never block their vision or become a major hindrance. When humans domesticated sheep, we deliberately bred only the ones that had the most wool. Every generation, we'd breed the wooliest 10%. The resulti... |
How did they discover that adding all those random ingredients together would make a cake? | It is sort of evolution. You start out with our ancestors cracking open eggs and slurping the liquids inside. Some other ancestor found wild grass seeds and chewed on them. A third one saw a calf drinking from an utter. A fourth one found salt either in a cave or on a rocky shore. A fifth one ate some sugar beets or su... |
What makes the ejaculation of seminal fluid feel so good during orgasm and why does this sensation differ from urinating? | Part of it is evolutionary; to encourage you as a male to propagate the species. First, there is a lot of stimulation which occurs before, during, and after orgasm all of which are *usually* deemed pleasurable; arousal, touch, build up, and orgasm. All of these reinforce the desirability of the act of copulation . When... |
When discussing a cars performance, why are 0-62 times sometimes used rather than 0-60 times? | Because 62mph ~100 kph. It makes it easy to understand rather than posting a 0-60 mph and a 0-100 kph, you can just use 0-62 mph. |
How do school TV systems work? | You should for sure take that class. There are basically faders and computers that people operate, as well as audio people and people that push play on recordings. If you're asking this question, you're 100% guaranteed to enjoy this course as much or more than anyone else.What /u/Messisick said. But the way they go "li... |
Why did it change from Chinese New Year to 'Lunar New Year' if multiple other cultures have lunar calendars with different dates for New Years (ie Islam, Judaism, etc)? | It is technically called Lunar New Years because, as you know, the calender is based off the phases of the moon. It is commonly called Chinese New Years in the west because "white people" first heard of this from the Chinese immigrants who came during the California Gold Rush of 1849 to 1860s. Chinese New Years has bee... |
Why do some dishes heat up quicker than the actual food contents? | Today you learned there's a difference between scold and scald.Certain materials have different heat capacity. This affects how quickly it warms up, and how long it stays warm for. Water has a high heat capacity, which means it takes a long time to heat up, but it also takes a long time to cool down, whereas something ... |
Why do extremities puff up when they experience frostbite? | Frostbite occurs when parts of the body get so cold that the water in the cells freezes. When water freezes, it expands. This bursts cell walls, including arterial walls, and can cause fluids to leak into surrounding tissue instead of continuing to circulate around the body. This leaked fluid builds up over time and ca... |
How fast do you regain blood lost and what are the downside of having less blood in the body? | All of the components of the blood are replaced at different speeds. It takes about 4-6 weeks to completely replace the red blood cells, which are the oxygen-carrying components of the blood. Drawing a bit of blood does not really have a major effect on the body because it's a small proportion compared to the overall a... |
How do we know/deduce what color dinosaurs are? | We don't. It's all just educated guesses based on the animal's supposed environment and modern relatives. |
Is sign langue the same all over the world? | No. You have many different sign languages, and some languages differ between countries. American Sign Language is different from British Sign LanguageSign language isn't the same across languages and sometimes it's not even the same across countries. American Sign Language is Different from British Sign Language to th... |
Why do some people come on the Daily Show? | America has become so partisan that conservatives, especially older ones, really have little clue what the Daily Show is about. So when they call they agree to it not realizing that they are going to be made fun of . Not everyone is politically savvy and the Daily Show takes advantage of that. They've become too well k... |
How is the panel of judges determined for Olympic events and how do they ensure that the judges aren't biased towards a certain country? | Well in London 2012, in the women's epee fencing semi-final, the timekeeper delayed starting the clock so that time wouldn't run out and the German fencer would have time to score a touch on the South Korean fencer. So whatever system is in place, it's clearly not perfect. |
What about Subway makes it so unhealthy? | Subway brands itself via subs like the 6" veggie delight or turkey which are relatively healthy. However, when most people order at Subway, they order much less healthy options are much higher in calories, fat and sodium than the worst McDonald's hamburger. |
How does a quantum computer collapse into the right answer? | You don't. I know that answer makes people cringe, but that's the point of quantum mechanics. A traditional computer typically works by reading a high or low voltage. When you're talking about quantum mechanics you're dealing with spin states of electrons. There's a possibility to where you won't be able to distinguish... |
Why are there creases in our palm and why are they permanently there throughout our lifetime? | Creases form on our hands in the womb. They allow our hand skin to squeeze and stretch without bunching up. These creases are called Palmar Flexion creases. |
How some people can will themselves awake without the use of an alarm. | Habit. I've woken up at around 6AM for the past 6 years. Except for the weekends when I stay up late, I generally go to sleep around the same time during the week and usually wake around 5:55AM. I still set an alarm though in case I happen to not wake up by myself. |
Why is it called Hardy's on the East Coast and Carl's Jr. on the West Coast? | Because Carl's bought Hardees. Instead of changing Hardee's to Carl's, they kept the name and gradually changed the menus to be pretty much the same things. I would guess that Hardees has a loyal following, so they left the name alone. |
Why do humans generally avoid eating other predators? | As far as I know, the main reason is cost. If we want to farm meat, we can either: - Grow crops, feed them to herbivores, and eat those, or - Grow crops, feed them to herbivores, feed those to carnivores, and then eat them The first one is cheaper - more meat per unit of crops, plus one less stage in the production .It... |
Why are there harmful chemicals in cigarettes? | The lists of hundreds of harmful chemicals you see are things found in cigarette *smoke*. The analogy I like to use is that burning a cigarette is the chemical equivalent of a tornado hitting a house. If you walk through a house after it gets leveled by a tornado you might think "Man, there's all kinds of splintered wo... |
Non-HD TV looks worse than it did years ago. Have I just adjusted to HD or is the quality actually worse? | A lot of TV channels are more and more heavily compressing their signals in order to run more channels. For example, here in Australia, 7 used to run at 10Mbit, then they switched to 7Mbit on their main and 3Mbit on a secondary channel, and now 4Mbit/3Mbit/3Mbit across three channels, all of which look a lot worse. It ... |
Why do cars tell you if the passenger airbag is on or off? | In some cars the passenger airbag gets disabled if no one is sitting in that seat to prevent having to pay to have it replaced in the event of a collision. The indicator light is a fail safe of sorts to let you know if the airbag is actually on when someone is sitting in the seat Cars have a pressure plate in the passe... |
How is it allowed for publishers to make textbooks and homework codes so expensive? | What do you mean by "allowed"? Who would have the power to prevent publishers from charging what they want to charge?Because what else are you going to do? I hate to sound like an ass, but that is exactly the reason. Your professor told you to buy it, and you have to. Period. Since the professor does not have any veste... |
Why isn't the Flint water crisis fixed yet? | Short explanation: the water quality problem is due to a sprawling, hard-to-access system of outdated plumbing infrastructure. This is hard to fix and the local/state government does not have much money. Specifically, they have much less money than they did when they laid the pipes, which was a time of economic prosper... |
Do reincarnation theories account for population growth, and if so how? | The way it was explained to me is that reincarnation isn't linear in time. You can come back at any point in time, even at the same time as previous or other versions of yourself. You can even be friends with yourself. One of the crazier but awesome ideas I've heard is that all life on earth could all be the same being... |
How can cybercriminals like people behind ransomware stay anonymous when receiving money? | I don't know exactly how they did it in past years, but these days, they've started demanding money in bitcoin form. Bitcoin lends itself very well to anonymity, if done right. |
How were different languages first translated? | Daniel Everett cracked the language barrier with the Pirahã of South America. I watched what I believe was a TED talk about it and he commented on this matter. Social barriers aside , he says you pick up a stick and you say "stick". And then you write down phonetically whatever they say. Then you pick up a rock and you... |
How come some shows blur faces where others do not? | In the UK, you can show faces if they have been convicted for what they are being shown doing. Truth is a legitimate defense against a defamation action in most juristictions. However, if you showed an action that could be interpreted in a way other than it is being portrayed, you might be in difficulties if it hadn't ... |
What happens in America if someone rings 911 for an ambulance and that person is dying, but they do not have health insurance? | The ambulance comes. They get cared for, taken to the emergency room, get treated. Then they start getting really large bills that they cannot pay and end up declaring bankruptcy. |
The relationship between Rome (the city), the Roman Republic, the Roman Empire, the Western Roman Empire, the Eastern Roman Empire, and the Byzantine Empire. | The City State of Rome is where it all started. From there, the Romans conquered the surrounding territory to form the Kingdom of Rome. In 508 BC, the last king of Rome was overthrown and the Roman Republic was instituted in it's place. In 27 BC, Octavian became the Emperor of Rome, converting the republic into the Rom... |
how can we know things like how far away planets are from the sun, or how large the sun is? | Parallax. It's a way of using simple geometry and observations to calculate distance. Orbits are ellipses, which are geometric shapes, which means if we can measure some parts we can calculate unknown quantities. Kind of like how you can measure the hypotenuse of a triangle if you know one of its sides and an the angle... |
Why does club soda taste salty when bubbly and sweet when bubbles run out? | Carbonic acid. Club soda is water plus CO2 bubbles. But flat club soda is not just water. Dissolved carbon dioxide actually changes the water. Water with dissolved CO2 is called carbonic acid and like it's name suggests, is mildly acidic which gives it a slightly bitter or vinegary flavor. Club soda also often has non-... |
What's this ongoing drama with Benjamin Netanyahu about? | He is also going to be addressing the US Congress in a couple weeks, which was controversial due to the circumstances of the invitation being extended. Additionally, he is coming under fire for his personal expenses.I'm not sure if this is what you mean, but with the latest anti-Jewish terrorist attacks in France and D... |
Are 'Tha' and 'Thee' as in "Tha Home" and "Thee Houses" two separate words, two separate pronunciations, or some other plural english weirdness? | The two pronunciations of the word "the", that is, sounding like 'tha\' or 'thee,\' follow the same rule as "a" vs. "an." When the *the* follows a vowel sound, you use 'thee\' . And if the doesn't, you use 'tha\' . They are both only one word, howeverPronunciation of "the" is entirely arbitrary. You can say 'thee\' or ... |
Why American films/tv shows look so different to others... | It's partially a technical issue, America has always had a different TV system to most of the rest of the world. Traditionally it was 525 lines and 30 frames a second, whereas almost everywhere else was 625/25. Therefore American programmes have always looked a bit odd here in the UK and there's presumably the same iss... |
