⃣ what Linux is and how a normal pc/windows user would ever use it. | Linux is an operating system, just like Windows. It is installed on a PC and used just like Windows would be. There's very little difference. Last week, my wife ordered a case, motherboard, processor, power supply, DVD, hard drive, and a few other things from newegg, assembled them, downloaded Linux and installed it. S... |
How redundant is "The Cloud"/Google drive and how do they make sure I never lose my data? | Google is ludicrously backed up, beyond all reasonable levels. There's reasonable evidence that they are maintaining backups of *everything* they have access to . Losing data isn't a thing that they're going to do.Companies store multiple copies of your data. For business customers, a contract will specify redundancy. ... |
The Gold Standard is 99.9% gold. But what is the 0.1% made up of? | Impurities. A standard of 99.9% gold means **at least** 99.9%, it could be more. You can't say 100% because if there is even one atom of something other than gold, that is not true. So you pick however many 9s you want and call that good enough. The remainder isn't anything in particular, just whatever is left over fro... |
Why is fruit good for you but fruit juice bad for you? | Most juices don't keep the pulp in. The flesh of the fruit has a lot more nutrients than the juice does. Do you eat meat? Think about it like drinking the blood of the animal instead of eating the meat: a lot of nutrients are missing, and it's not nearly as good either. If you want all the nutrients, go for a smoothie ... |
How can we continue growing seedless fruits? | Basically, they're propagated by cuttings. Bananas are a good example. Because pretty much all bananas are coming from the same plant , if a blight/fungus ever develops for it, it could wipe out all bananas, and we'd have to develop a different variety. |
The metal thing they press on fighters faces between rounds. | I believe it's cold like ice to decrease the swelling. Probably made of steel so it can be sterilized between fights. |
When commercials say "call within the next 5 minutes" do they really mean it? | No, I'm pretty sure it's to get a person to make a snap decision, as a technique to lure more buyers. That's my understanding of it |
Does having more blades on a Helicopter make a difference? | The speed limit of a chopper is directly affected by the maximum speed of the tip of the rotor on the forward moving side. If its speed relative to the air approaches supersonic speed you'll get nasty aerodynamics, so you can't get above that. An increased number of rotor blades has improved lift compared to a rotor wi... |
The story of Minotaur and what it symbolizes. | I may be wrong, but doesn't a labyrinth only have one path through, so you can't get lost? It winds around itself to make the walk longer than it would be. A maze is the one where the pathway branches off into separate paths that lead to dead ends. |
How Do Blind People Locate Signs That Have Braille? | [Here] is a thread asking basically this exact question. It's got a number of good answers. It's worth reading, but the short answer: > There are standards for where signs have to be located. A blind person picks up on these routines; a sign is going to be the same height and the same distance from the door frame wheth... |
why people with autism are usually recognizable | I'm not sure what you mean. I have autism and nobody knows until I tell them. They just think I'm weird, or different.A good friend of mine has autism.and REALLY REALLY hates getting a haircut . He would get nervous days, maybe weeks before getting his hair cut and kept prolonging the apppointmemt Although this does no... |
How do people in wheelchairs not get fatal blood clots? | I'm in a wheelchair due to a form of MD. I haven't had any blood clot problems and take no medication at all. What I do suffer from are small leg & ankle ulcers due to poor circulation. These are checked regularly and sometimes require antibiotics to kurb infection.Nursing student here who works frequently with geriatr... |
Why cant we point a space telescope to see living beings on habitable zoned planets in other galaxies? | The universe is fucking massive. There are billions and billions of galaxies, each having millions and millions of stars like our sun, each having multiple planets and moons orbiting them. Looking at all of them for life would take a very, very long time. Also we haven't yet had the capability to zoom in enough to see ... |
Why can my eyeglasses take constant dropping and abuse while my phones screen is so delicate? | The lenses in your glasses are thicker, and they are curved . They are also probably made of plastic, which is less prone to cracking. And your glasses don't have the added weight of the phone, which adds kinetic energy to the impact. |
What would actually happen if there is a government shutdown on October 1? | Federal government services will be classified as essential, and nonessential. Nonessential will get shut down or put into a dormant mode with minimal staff, essential will continue, many with reduced staff and/or service hours. Many gov't contracts will be suspended. You probably wouldn't notice a short term shut down... |
Why is only blue and blank ink accepted as professional? | It is easy to read and is copies well. Also, a piece of paper isn't a contract, a contract exists when we both agree, whether it is written down or not. The paper is *evidence* of the contract. In theory, you could write a contract in orange crayon on a napkin, but that would be weaker evidence, and easier for someone ... |
How do reddit "power users" like /u/pepsi_next submit 100+ links every 5 minutes and not get banned as bots? | Just did some extensive research on his posts. I feel dirty. Mainly because there's cum everywhere now. |
Why do we think verbally? | It is thought being processed through out the brain. It is all being interpreted just as if someone were speaking to us. Your brain analyzes the information, therefore it feels as if, ''you're speaking'' to yourself.Not everyone thinks verbally. I tend to think with images, although describing the significance of the i... |
The vaccination war: Aren't the only people at risk those who don't vaccinate | The measles vaccine is one of the most effective vaccines there is, and it still has a 3% rate of failure after two doses. Assuming a population in which 100% of people received the vaccine, 3 out of every 100 on average would not be immune to the virus. However, the chances of a healthy person coming into contact with... |
How can the sound barrier walls being along busy highways in new residential areas be worth the expense? Are they really effective? | No, they're highly effective at blocking *and reflecting* sound, especially compared to them not being there. |
Why are there so many holidays around 25th December? | The other answers are correct, but I'll just add that Kwanzaa is the same time as Christmas because it was specifically created as an alternative to Christmas, and Hannukah commemorates the Hasmonean revolt which just happened around the same time. |
What is the purpose of a clutch in a manual transmission? | I don't quite get the engage/disengage part - when you press down the clutch pedal, are you disengaging the engine? |
Why isn't Google+ really popular? | I think they kept it too long in invite only, but other reasons might contribute to why it hasn't caught on. I do think that the more Google pushes it as a platform to access or use their other products, its popularity will increase. Some people say that's unfair or shady, but it's actually good business. |
What the film Eraserhead is about | I feel like I read somewhere that David Lynch stated no one so far had correctly interpreted the movie. I thought I read it on IMDB, but I can't find any statements like it there.Who are your parents, kid, and why the hell did they allow you to watch *Eraserhead*?The pressbook says it best. "A dream of dark and troubli... |
What causes high rent prices like in San Fransisco? Wouldn't competition from new developments level out pricing? | It's mostly just still supply and demand. There isn't a ton of land in SF, and building up is very very expensive. Even if they built a ton of places, the supply would still be far higher than the demand. In addition, SF has a huge amount of very high-income people, so these people are willing to pay a lot for housing,... |
Can someone explain the new EU GDPR and how US companies can get fined for non-compliance? | EU laws affect companies doing business in the EU. If you want to sell a product in the EU, you must follow EU regulations to put a physical product in the EU. If you don't have a physical presence in the EU, as with software companies, this doesn't matter **unless you have a business presence in the EU**. Many tech co... |
Why do big cities have higher costs of living/wages? | They have higher costs of living because there's a limited amount of room available. This then means wages have to be higher for people to afford living there. |
I am 31 years old and could never understand algebra in HS or college. I had to do some math today and suddenly everything clicked and suddenly I get it. WTF happened? | For me, it's a lot harder to grasp an abstract concept that doesn't mean anything. But when you apply it to real life, you can see what you're trying to accomplish. It's tangible, and you care. |
Is there anything scientific behind homosexuals who develop a lisp? | See _URL_0_ I'm curious as to why this question has been asked so many times recently.It's a social thing, not a physical thing. Depending on what you mean by "scientific" that may be a yes or a no. To learn more, use the search. It comes up quite a bit. |
A car has a 2.5L 4 cylinder engine. What does this mean? | The cylinders themselves, where the gas and air is sprayed and combusts, will combined add up to 2.5 liters of volume. It varies a lot, the size of and number of cylinders certainly helps, but there are other methods to get more power out of an engine. Turbos, for example, compress the air into the cylinder, so there's... |
If potential energy is larger the higher I go, Is it harder to hold a cat at arm level at 1 km up vs ground level? | No. It would cost more energy to get it up there, but once you're there it would actually be slightly *easier* since you are further away from the center of the Earth and gravity is weaker. Potential energy is the amount of energy stored in an object based on its position in relation to a force. In the most common case... |
Why do piano notes keep playing when you hold the key down? | A piano uses groups of strings, a felt hammer, and bar that lifts off the strings to allow them to vibrate, and silence them when the key or sustain pedals are lifted. When you press the sustain pedal, it lifts this bar off the strings, allowing them to vibrate. Even if a string is not struck by the felt hammer, it can... |
If electric cars take the place of regular cars, won't the production and disposing of the batteries be an even bigger strain on the environment? | Lithium ion batteries are considered safe for landfills, as they contain no lead. However, they will likely all get recycled anyway to recover the metals inside, which isn't a terribly toxic process if done properly. |
Why are energy drinks with zero sugar or calories bad for me? | Isn't it because of the crazy amounts of caffeine in them that's not good for your heart? |
Why do these fancy restaurants all serve tiny portions or odd dishes I've never heard of? | First off, the meals themselves aren't tiny. This is a common misconception. You get small portions per dish, but you get a ton of dishes, usually 5-6 plus dessert. You will certainly be full after the meal. They're small portions so you can try a bit of everything. Going to a fancy restaurant is a rare event for most ... |
What is engine braking? | It's the process of manually shifting the vehicle into a gear that is not efficient at the vehicle's current speed, thus slowing the vehicle. |
How is it fair/what is the justification that a presidential candidate can win popular vote and still lose an election? | The president is elected by the states, not by the people . If you win the support of states which have a majority of the votes, then you win the election. It's the same idea as Congress, where laws must have a majority of the people and a majority of the states . It's not practical to require both majorities when voti... |
The difference between an Empire, Kingdom, Duchy and Republic. | The difference between an empire, kingdom, principality, caliphate, sultanate, and duchy is primarily the title of the monarch; emperor , king , prince, caliph, sultan, or duke . There are slight differences between type of monarch, but they also overlap in many cases so I don't think the differences are really that im... |
How much can my company monitor while using wifi? | They definitely can see all of that. However they may have trouble identifying exactly who you are if you are using a personal device. It might be that they can get some very specific data, like the name of your phone, the MAC address, etc. But if you are logged into public wifi then they may have trouble finding out *... |
If you stick food in a vacuum sealed chamber will it decay? | If you have water in a vacuum, it'll start evaporating. This is actually used to evaporate water if you don't want to heat the liquid up, for example when making juice concentrate, removing alcohol from beer, or freeze drying fruit. But if you have a fruit that has a protective shell, for example a watermelon, it would... |
how is the job market able to accommodate the increasing number of college graduates per year? | By devaluing the value of a college degree. It's a form of inflation. It is basically considered at this point to be a staple of your education that you have some form of degree, as opposed to it being a noticeable achievement. If everyone in your class got B's then you are noticeable for having gotten A's. If everyone... |
Is it legal for a United States president to change a law without congressional approval? | It is not legal for a President to change a law without the approval of congress.The ACA has been delayed several times, and it is probably legal for the President to do that. However, the Obama Administration is currently offering subsidies in states that have not created Health Exchanges. The law only allows subsidie... |
Jury Duty/Jury Nullification (USA) | They'll call in a whole bunch of people. Every one of them will get asked questions from the judge and the lawyers from each side. The judge can dismiss people from the jury for any reason he or she wants. The lawyers are allotted a certain number of people they can dismiss from the jury, and they do dismiss jurors for... |
How come when you're really hungry, to the point where you're shaky and feel nauseous, that if you wait, your stomach starts to hurt bad? | I would imagine it would have a lot to do with hormones and brain processes. Your stomach doesn't actually have any acid in it when you're not eating. It drains the mixture of acid and food called 'chyme' into the duodenum of the small intestine shortly after eating, then contracts and shrinks to it's resting state. If... |
What is BPA and why should I be scared of it? | It's a chemical called Bisphenol-A and is used in making certain plastics, including those used for liners of canned food and plastic bottles. The chemical has the ability to act like a hormone receptor in the body, which can potentially lead to problems with the nervous system and endocrine systems. There's some contr... |
Why does the same water feel colder on your hands than it does in your mouth when you drink it? | Probably because your spit isn't the same temperature as your hands So your mouth is used to feeling colder then your hands |
I can't think of a single Chinese food that has cheese? | A lot of Americans are surprised to learn that lactose intolerance isn't a deviation from the norm, the *majority* of humans are lactose intolerant. And it kinda makes sense, doesn't it? We evolved to drink milk from our mothers' breasts, not from cows. Our stomachs weren't made to handle cow's milk. But humans started... |
Why Scaring People feels so rewarding? | It's a dominance thing. On some primal level, you outsmarted them and could have hurt them, but didn't. They thought they were in actual danger and saw the scenario flash before their eyes. You're the top dog.Because scaring someone is taking control of their mental state, in essence, controlling them. If you like scar... |
What is the difference between 'spectrum' and 'gamut'? | As both can assume various meanings there isn't a precise difference, but generally speaking, a gamut is the full range of something . A spectrum can refer to a full range also, but often where the values within that range are undefined, such as electromagnetic frequencies - the primary origin of the term. |
In the U.S., how does policy allowing coal mining waste drain into streams help create more jobs? How is it in any way beneficial? | It doesn't. Coal is largely expensive as a source of energy in the US compared to any other fossil fuel. Some politicians thought that they could win an election by tricking people in coal mining country into thinking that jobs would come back to their area if regulations on coal mining were eased. If you were to drop ... |
Why did the hippie movement end? | We grew out of it. Once the 70's started marching on, most of us grew up, got married, settled down, found a job nothing earth shattering. By the time the 80's arrived, other than for a few hold outs and burn outs, the hippies had all become part of the establishment. |
how does capping the number of US House of Representative members as we do today mean less representation for urban city residents? | Because there is a minimum number of representatives a state can have, which is 1. Many of the more rural states wouldn't qualify for one any other way, so they 'take' delegates which are 'supposed' to be for the populous states. Though I like that better than a congress that needs to be housed in a stadium.Until 1964,... |
why haven’t we built a space station on the moon yet? | Its massively expensive, and there's just little political willpower to do so. Its being worked on around the planet, but less money from governments means less progress is made each year. |
why isn't PETA getting sued into oblivion for their "pokemon black and blue" edition? | Well, it was just released recently, right? Nintendo might not have heard about it and had enough time to send them a cease-and-desist letter yet. Usually, companies start with a take-down notice or cease-and-desist letter before they go all out with a lawsuit. Actually ramping up into lawsuit mode costs time and money... |
If there are sites, such as AliExpress, that sell products for incredibly low prices, why are sites such as Amazon so widely used? | AliExpress sells cheap, off-brand, Chinese products direct from China. You don't really have any guarantee of quality, you might wait 2 months for it to arrive & you're sort of fucked if you have any issues and want to return products. There are some gems in there, but you never really know what you're buying until you... |
What would the objective economic effects be if the United States allowed immigrants to freely come, work, and pay taxes? | OK let's assume a massive influx of new immigrants into the U.S. above what is already going on. Like, 2,3,4,5 times as many. At least. Considering there is already a 6% unemployment rate in the U.S., you'd need to find jobs for these people. Which means you would need to create jobs through public works projects, or j... |
What were naval battles (with cannons, muskets, etc.) actually like, and how were they different from what we think of??? | This is probably a good question for /r/AskHistorians. It wouldn't be a bad idea to post it there. |
What would really be the impact if everyone in the world stopped wasting food today? | On a small scale, it can make a difference. I volunteered at a rescue mission that did a very good job of turning donations into meals. We'd feed 80 to 120 people lunch every day with donations from farmers, Walmart, Chick Fil A, etc. They were good, balanced plate lunches that were pretty tasty. Especially during the ... |
Why does Socialism not exist anymore? | Almost every economy on Earth is a mixed economy. They have pieces of socialism, and pieces of capitalism. It's sort of like saying that America doesn't have any capitalist ideas just because it has welfare. |
Why is gold so valuable? What keeps the price so stable/high? Why is it a good investment? | Gold has value because we decide it does- the factors that make us value it are : * Rarity. There's actually not that much gold in the world if you look at it- all the gold mined in human history could fit into a cube 20 meters on a side. That's not really very big.* Beauty. We use it for jewelry and art, and it's valu... |
Since millions of years ago there was a much higher oxygen content, did fire behave any differently? | While these answers are interesting, I don't think any of them answer the original question. While fires were more frequent and faster moving, was the nature of these fires any different than the fires we know today?", 'Long story short, the more oxygen in the atmosphere, the faster fire can travel. I am sure wildfires... |
How can a 4K video look clearer on a 1080p display even though there aren't as many pixels on the 1080p display to show more detail in the 4K video? | Ok this is the second time in a week where the most upvoted answer is wrong. It has nothing to do about bitrate. The correct answer is already here in this thread. /u/MissArelin_URL_5_ /u/UniqueNameIdentifier_URL_3_ /u/michaelrcarroll_URL_4_ I sell apples Some kid comes to me and asks for 16 green apples and he's reall... |
Why is the primary braking force on a motorcycle applied to the front wheel? | On top of all the responses already here, a motorbike is heavy and has its centre of mass low. Pushbike is light and the cyclist sitting all the way up on the saddle makes for most of the mass, giving it a very high centre of mass. Therefore, a pushbike can easily flip, for a motorbike it's nearly impossible unless you... |
why is picking scabs satisfying? Shouldn't the small pain and delayed healing make us instinctively hate it? | You don't want an answer from this subreddit. I am not an expert but I strongly suspect the top voted answer is speculation. Try asking this question /r/askscience. There are verified experts in medical science there that can help you, it's also more heavily moderated for quality scientific answers.To the person who co... |
Why is it that homosexuals are considered to be born gay while pedophiles are considered to have a mental disorder? | the way i think of it is as such; straight orientation is the acceptable norm, it is 'average'. being gay is accepted because it involves two consenting parties and number's wise, nearly average. however, being attracted to children, having an attraction to animals, and those who are into inanimate objects, etc - isn't... |
Programs such as PCMatic, Advanced System Care, and Make My PC Faster | No, they don't. Some might if you don't know how to do basic maintenance of your pc, but they'll slow it down by virtue of being there.As far as I am aware, no, they do not. Generally programs that promise "we'll make your computer faster!" are a load of crap designed to get the computer-illiterate to pay for something... |
Why is the picture-in-picture feature basically dead in modern TVs? | That's cool that you actually got it to work properly. But we never could and there is no sound for pip. But most houses have multiple screens that are light and and don't take up much space. Old tube and rear projector tvs where big and heavy. When most kids have a TV in there rooms you don't need pip. So it's an obso... |
Why did Portugal's drug addiction rate halve after drug decriminalization instead of increasing? | I'm portuguese and this makes me proud!Some years ago our countrie started to be very liberal about this type of stuff, for exemple, all people can start to drink by the age of 16!All these measures educated people and where really good for the population.The number of addicts droped a lot |
How are dice fair? | YOU ARE 100% CORRECT But there's so little difference it doesn't really matter with most dice. If you roll a dice 6 billion times you might get 1 billion and 5 1s. But in everyday rolls its good enough. There are other forces the weight difference has to overcome for it to matter. Things like friction from the surface ... |
Why do cucumbers melt the cheese when placed next to a slice in a sandwich? | Not sure, but as an educated guess, I would surmise that the cheese is leeching water from the cucumber. Cucumber's got a fairly high water content, after all, so the cheese may just be getting waterlogged, not melted.Because you use crap processed cheese that absorbs water from the cucumbers. |
Why is the median household income gone relatively unchanged for the bottom 90% of Americans since the 70's? | Inflation increases, while employees stick to the same wages. They earn more for less labor costs which benefits the companies but not the employees. This is why there is a minimum wage system. In all respect, it's about making money, not giving your money to employees. |
if a movie isn't finished, how are the trailers made? | They are finished scenes, movies are made in sections and edited together at the end. The movie isn't shot from beginning to end, depending on location, actor availability, and what may be needed to make a sceen set, the end or the action scenes,could be the first part of the movie made. Some senses are also made first... |
How does Stockholm Syndrome work? | A hostage situation is traumatic. The hostages begin to associate themselves with the takers because they begin to believe themselves also as under siege by the police, for example. Humans are social creatures. They try to join a community. Sociopaths would not experience Stockholm syndrome. They don't experience empat... |
Inoculation/Vaccination. If you purposely infect me with a disease you're trying to prevent me from succumbing to, why don't I get sick/die? | To add to the correct responses about weakened or dead viruses being used, in some cases it's also possible to just use a particular protein from the outside of the virus, so you don't wind up with any viral DNA from the vaccination at all. Your immune system learns to recognize this protein, so if the full virus does ... |
What's Going on When the Gas Pump Shuts Off Every Few Seconds? How can I prevent it? | Do you drive a Saturn? Everyone I know with a Saturn has this problem. There's not much I've learned you can do. My problem stopped when I sold my Saturn and got a non-Saturn. |
Why do warmer regions (tropical/desert) seem to have so many more poisonous/venomous plants and animals? | This would probably get more and better answers on /r/askscience. They won't use much jargon and they'll actually know! |
why are credit cards so poular in the us compared to europe? | I'm assuming you are from Germany yourself? It's mainly a difference in cultural development. Americans, if you allow me the really broad generalization, really enjoy their comfort and convenience. Credit cards by nature just make the whole shopping experience so much easier. It also doesn't hurt that your credit score... |
Why are humans afraid of rejection? | I remember this answer given on Vh1's Pick-Up Artist from years ago, so take it with a grain of salt But supposedly, back when people lived in smaller tribes and societies, you may have only interacted with a small amount of potential mates in your lifetime, and there was a good chance that they all knew each other. So... |
Why is 60 a common level cap for RPGs? | I don't know if this is the reason, but 60 is really divisable: 2x30, 3x20, 4x15, 5x12, 6x10. You can structure different ability and attribute bonuses on these intervals. Just a guess. |
Why government agencies can't/don't proactively stop spammers. | Governments consider this a very low priority problem. They're generally far more interested in sending soldiers all over the world to kill people, or do other things that greatly increase their power, than doing things that will help out the common man. |
Why do people say you are only contagious with a fever, when you can spread germs long after a sickness to a door handle or steering wheel? | I can't speak for your doctor, or what illness is being referred to, but generally this is not true. It is, however, a semi-popular myth about contagiousness, which some people will repeat, like any other number of untrue but oft repeated 'facts.' |
Bicameral legislatures - how do they work and why do they exist? | Probably the oldest example of a modern bicameral legislature is the United States Congress. The House of Representatives is the lower house and the Senate is the higher house. The rationale behind the U.S. Congress having two houses was a compromise between the large and small states. The number of representatives app... |
Why don't criminals just burn the bodies of murdered victims in their fireplace? | Several reasons. First - Burning human flesh gives off a distinctive and unpleasant odor Second - The human body does not fully burn, our bones usually don't as an example Third - Criminals aren't that smart |
Why does the moon look reddish on certain days? | When the moon firsst comes over the horizon, the light reflecting off of it must pass through more of earth's atmosphere. Our atmosphere scatters light, so when you go through more of it, the color distortion is greater. The moon turns white later on because the light has to pass through less of the atmosphere. |
If dust around a house is dead skin cells, could a forensics expert tell who was at a scene by examining the dust? | Long time lurker here but I signed up just for this. The idea that household dust is up to 80% skin is really pushing it. It comes from ideas in the 70s and 80s and was sold to the public by pest control companies. While dust does contain human skin sloughed off by everyday activities the skin is difficult to find and ... |
Why do people enjoy music more when it's turned up loud, compared to at normal levels? | I agree with most of what people have said here, but also I have found that turning up the volume helped me notice a few things different from the song that helps my listening experience. Like I could hear the background singers better, or notice new notes of a paino I didn't quite hear, or maybe even some special effe... |
Why are nipples coloured differently than the rest of your skin? | My parents always laugh when they tell the story about how they thought I didn't have nipples when I was a baby. I guess you couldn't see them or my eyebrows. |
The difference between Architects and Engineers in the design of a project, and how they work together | Here's a rough oversimplification: An architect is an artist. An engineer is a technician. However, architects have to understand math and physics, and engineers need to understand human interaction with their design.This is a very simplistic description. Architects know a little bit about everything , but specifically... |
The Body Positivity/Fat Acceptance movement. | I like your question, but I don't think anyone is being aplauded for lack of health. I think there is some pushback on the health of the ideal healthy weight . Our ideal is miserably skinny. But I also think there is a desire to not use weight as the measure of health. If we looked at blood sugar, cholestoral, and bloo... |
How China became the factory of everything? | China had a ton of people and a ton of savings to invest. China's government runs most of the biggest firms in China, plows the governments savings into them to grow them and is willing to operate at a loss to keep people gainfully employed. China's SOEs were hugely important in directing investment into low skill manu... |
what are the fundamental differences between a police officer, a sheriff, a deputy, a ranger, etc.? | Jurisdiction, mostly. **City Police**- usually cover city. **Sherrifs** - usually cover a county. **State Police** - handle crimes that span multiple counties within the state **State Troopers** - handle only State highways & State govt security It's designed to make sure there is a balance: Enough resources to handle ... |
Why do we need Oxygen to live? | Imagine a candle sitting on the table happily burning away it's fuel, while releasing heat energy. It works because the fuel reacts with the oxygen in the air, this is called combustion.Put a glass on top of the candle, and the flame will die because it lacks oxygen. Your body does something that's a bit different to c... |
I have a question on Ohms and Speaker impedance. | I've searched tha seven seas fer an answer. Yer not alone in askin', and kind strangers have explained: 1. [Speaker impedance and amp loads. ] ^1. [ELI5: the Ohm rating on guitar amplifiers and why it's important ] ^1. [ELI5: Matching stereo amplifier with speakers using ohms ] ^1. [ELI5:Guitar amplifier and speaker oh... |
How do people manage to create these "0 calorie" food items such as in drinks whose counterpart may have many more calories? | Calories are a measure of the energy that food gives to us. So if you eat something like sugar or fat or protein, our body has the ability to break it down and basically burn it for energy. But if you eat something that the body can't burn, then it doesn't give you energy - 0 calories. If you swallowed a small rock, it... |
Why do we have to learn history in school, and to such an extent that it is considered as important as Math and Science? | This post borders between eli5 and /r/changemyview. If you're looking for more debate/convincing, I'd recommend deleting this and reposting to changemyview. If you're looking for a straightforward, simplified explanation, this is the subreddit for you. If this turns into more of a debate, a moderator will come by and r... |
Why are indefinitely high speeds allowed on the Autobahn? How can the freeway design account for such high speeds (in terms of safety)? | Most people believe that the entirety of the Autobahn is just do whatever the hell you want and go fast as hell. I've been to Germany and can tell you that there is a speed limit on a majority of it. It isn't just go fast as hell in your German super car and not care about the people around you. Most of the Autobahn ha... |
What is actually going on when i pop my back? How does this compare/contrast to when I crack my knuckles? | Crack your knuckles not your back. I've had scoliosis and just recently had a micro discectomy on my L5 for a herniated disc at 26 . Your spine is precious, never pop it unless at a chiropractors office for adjustment. I promise you, you're causing more harm than good. Popping and twisting will torque your back in ways... |
Why do some people insist that there is no such thing as different "races" when there is hard biological evidence that there are profound genetic differences? | Because many of the people who make that claim are more motivated by politics than by science. And they aren't exactly wrong, either. Far more harm has been done exaggerating racial differences than by underestimating them. Is splitting scientific hairs really worth giving bigots their ammunition? |
how people can be tracked with fingerprints. Is there some sort of universal database of everyone's fingerprints? What? | It's not a universal database - it's a database of people who have been arrested before. If you've never committed a crime before in your life, and go steal some shit and leave a fingerprint, they won't know who it belongs to. If, however, they are able to figure out it was you by some other course of events, they coul... |
How can you tell directions from sound? | Sound is slow enough at normal air pressure to arrive at slightly different times between our two ears. The difference in arrival time tells us the direction, and the change in timbre tells us information about whether it's above or below or in front or behind. The shape of our ears helps us to pinpoint sound as well a... |
