Why are there so many programming languages, what do they do, and is there a 'best' language? | There are so many programming languages because there are so many different types of things to program. Each language has its own strengths and weaknesses that make it ideal for a certain type of application. Programming languages are high-level ways to communicate with a computer's processor. They allow us to tell a c... |
Why does ingesting grapefruit and grapefruit juice interfere with my anti-anxiety medication? | I'm surprised I have not heard of people abusing grape fruits with their meds to increase their high somehow.Side note: I believe the goal is less than a quart a day of grapefruit juice |
Why is liquid water considered such an important factor in the search for alien life? | I would assume that water on other planets gives us the most optimism that life exists there simply because of what we know about life here on earth, and the conditions for it.It isn't necessarily a condition for alien life, it's just a great base for us to narrow down the search. |
What prevents a company from simply stating "We are not liable for anything." and it being true? | Any claim that's made like that, only has validity in as much as it agrees with existing laws. It doesn't supersede them. If the firework is faulty - they are liable. If someone used the firework in a way that is clearly inappropriate and contrary to clear instructions given, they probably arent.I ran two computer/elec... |
Why do terrorist groups like ISIS publicly announce when one of their leaders has died? | When a leader is killed by the enemy, there are three basic options * try to keep it secret, to keep the enemy guessing* be unable to keep it secret, and let the enemy announce it and take credit for it* assume it won't be secret, and get ahead of it, announcing it with your own spin, to reduce the PR spin the enemy ge... |
Process of buying a home--start to finish. | I bought my first home last year.. 1- get pre-approved for a mortgage 2- get a realtor 3- choose a house 4- put an offer on the house 5- go back & forth until both parties agree on price 6-both parties will sign a contract the seller will likely have a couple as well . You will also formally apply for your mortgage at ... |
How reliable actually is Wikipedia? | People like to correct incorrect information, so it is fairly reliable. On the other hand, vandalism is fun. A good way to figure out if a piece of information on Wikipedia is valid is to look at the source of the information. If no source is cited, proceed with caution. If the information is sourced from a peer review... |
Why do men and women (typically) have very different and distinct penmanship? | I remember reading in a book about handwriting back in the 90s that, among adults of similar education, contrary to popular belief, there were no consistent handwriting differences correlated to the person's sex. Apparently when people actually tried to identify the sex of a writer without knowing it in advance, they w... |
How can causation be distinguished from correlation? | If A is correlated with B, you have three possibilities: * A causes B* B causes A* some unknown factor, C, causes both Much of the effort of proving causality is searching for all possible C's and ruling them out. Once you have done that, it is usually easier to determine which way the causality flows, either by chrono... |
Why do we "space out" randomly? | I don't know actually, but I found an article on NBC that mentioned a study that suggests it has something to do with recall. _URL_0_ |
How you can make an SOS call without phone service? | Another point that I don't see being mentioned is that for 911 calls the transmit power of your phone is set to maximum. This will drain the battery faster, but there is a much better chance of connecting to a tower at that point whether it's on your own carrier or not. Additionally, the tower may also boost it's trans... |
Does your DNA change after a full blood transfusion? | Wow, thanks guys for all the responses. I was never aware that chemo and radiation were sometimes used to eliminate your original bone marrow. This is a question I've wondered for a while and I've never been able to get a solid answer! |
- Why do public restrooms have automatic soap dispensers if you will wash your hands directly after applying the soap? | Hygiene - 95% of people do not wash their hands correctly. To touch a soap dispenser or faucet or door handle is like touching the genitals of 95% of everyone who have used it. If I can't wash, dry, and exit without touching a surface in a public restroom, I don't wash at all. |
How have we not noticed a planet in our solar system 10 times the size if earth? | The only way we will be able to detect it definitively is by actually seeing it. We can do this in one of two ways, either this planet is large enough and hot enough that it emits it's own infrared light, and we use a detector to find that, or we see sunlight reflecting off of it and shining back to us. It's unlikely i... |
Why does it take humans in some cases over 12 months to walk when animals like deer can walk within a few hours of birth. | I've read that it is because we have such a narrow birth canal, meaning our offspring have to be born much less developed. |
Often in movies there are lines of dialogue (subtitles) that aren't possible to hear. | A lot of people are confusing closed captioning with subtitles. Subtitles only mean the lines of text on the movies for reading, and when used alone, generally only for spoken sentences. Closed captioning includes all noise related things essential to watching the movie, including explosions sounds and whatnot. Now to ... |
Does killing cockroaches lead to the future roaches being smarter? | Don't actively kill them, put out roach baits. Then they all get a nice last meal. I also really doubt that rocahes are smart enough to notice the reasons other roaches get killed, that is way above their brain level. |
Why is it impossible to exhale into a bottle? | It might be because of pressure.Within the bottle you have the same air pressure as outside of it. As the bottle is closed and you try to exhale the air can't go anywhere and therefore you have to compress the air inside for which your lungs are not strong enough. |
Does Microsoft make profit from giving Windows 10 away for free? | Microsoft is only giving away Windows 10 to people who already purchased a copy of Windows 7 or 8. It still costs money to put Windows 10 on a new computer, and enterprises still have to sign expensive agreements with Microsoft to get all the features and support they need. Upgrades were never more than a tiny portion ... |
If light slows down in water, how does it speed back up again when it comes out? | The Feynnman lectures have a good example.of this. Don't have time to search for a link but it's on the refractive index or permittivity stuff. It comes down to the light wave cause atoms in the new medium to oscillate at the same frequency as the incoming wave. They oscillate out of phase however. It turns out the add... |
How did people in the days before daily showers and teeth brushing not have terrible acne, rotting teeth, infections, etc? | Acne isn't caused by hygienic reasons, it's more genetic. Teeth rotting only occurs with modern processed food consumption check out some modern tribal pictures and see they have perfect teeth. Infections? Yeah, they had plenty of those. |
So... what happened to the Malaysian flight? | I dunno, but this season Lost sucks. Like, we haven't even seen the monster yet. |
Why do NFL teams claim they cannot survive without a brand new state of the art stadium? | Because the owner really wants a new stadium. Older stadiums typically don't have large amounts of luxury suites that they can charge insane amounts of money for. The 49ers for example, were able to collect 400 million from Personal Seat Licenses just for their luxury suites. Keep in mind those aren't tickets to the ga... |
Where do wild animals go when they die? | It's not like dead wild animals leave carcasses that persist for lengthy periods of time. The flesh is quickly consumed by scavengers, and what isn't eaten rots fairly quickly.Mostly because they disappear very quickly. In cities, humans clear them away; in the country, various scavengers make short work of the carcass... |
What gives certain materials a cooler ambient temperature than others? Why is metal cool to the touch even if a room is warm? | It's not the one is cooler than the other. Metal and plastic sitting in a room will both be at room temperature. However, metal is a better conductor of heat, meaning the transfer of heat from your hand to the metal is more efficient. Because your hand is hotter than room temperature, touching the metal will cool your ... |
why don’t cars have brakes when the ignition is off—Why shouldn’t we be able to use the brakes? | Most cars nowadays have power assisted brakes. Can't use power assisted brakes with engine off. Same goes with the steering wheel |
How is Tesla worth more than Ford? | People buy Tesla's stock anticipating great returns in the future. They think Tesla will become the dominant car brand, with electric cars taking over the streets. With all of these people buying Tesla's stock, the stock price rises, and thus Tesla's overall value also rises. Personally, I'm more skeptical about Tesla.... |
When suffering with depression, what is the physical feeling you get in your chest? Sort of like an actual sinking feeling. | When you're stressed and/or anxious your body has a physical response. This is called the fight or flight response. It is a way for the body to prepare itself for a treat, which we call stress. The muscles in our body tighten up, which also happens in the chest area. Normally your body recovers easily from this respons... |
Why does the brain feel the need to correct inverted sight? Would it make a difference if humans grew up with only inverted vision? | It makes more sense to me to think of it as having evolved along with eyesight itself. The inversion correction is really just one aspect of perception. All of our perception is a consequence of evolution. Perception does not represent reality. Perception is only what provided survival benefits to our ancestors. We mus... |
Is there a scientific explantion yet for why we're sentient? | It's an illusion. Your body and mind are nothing more than an extremely complex, deterministic machine. |
is my phone eavesdropping on my conversations? | I read somewhere that WhatsApp tracks conversations and uses it to target ads. So if you've been chatting about it that may be the reason. I'm sure there's a way to switch it off too in the settings. |
Why is it near impossible to watch Bluray films on PC, whereas there is no problem with DVD's? | The complexity and security around the copy protection was stepped up a few notches with BluRays to combat piracy, consequently it's difficult for application developers get access to the decryption keys necessary to play encrypted discs as the organisations involved don't want it to be easy for application developers ... |
WWE, how is it so popular ? | I'll list a few things that are attractive about pro wrestling. *its a never ending saga. No season breaks. No finales. Just a new show every single week. *a cast of characters close to 80 or 90 deep *real athleticism and talent required *incredible spectacle. Lights. Music. Pyrotechnics. Costumes. Tons of drama. *hist... |
why is the two dollar bill so rare? | Some people have believed that they're bad luck, and some others considered them evidence that a person had been gambling at the horse races, since $2 was a traditional minimum bet. But they also aren't sufficiently different from the other denominations. Say you buy something with a $5 bill in the price range from $0 ... |
Is "tolerance" psychological, or is there a physical basis for it (alcohol,pain,etc)? | I have a chronic pain disorder that most people get when they are older if they get it but I started having symptoms when I was 14 and it kicked in fully by 17-18. I'm able to handle the pain a lot better than most others with the same illness and that is probably because they spent a large portion of their life withou... |
How did Donald Trump end up with so much money? | I heard he protects the Trump name and owns another company named something else. If something he does is successful, its Trump enterprises all the way. When something starts failing, he 'sells' it to the other business, and the flawless Trump record remains 'successful'. That, and he started with daddies 200 million. |
How to cook chicken in a way that isn't bland or dry | Chicken is mostly water. The hotter the chicken gets, the more water is going to get out and dry out the chicken, so you need to make sure the chicken doesn't get too hot. You can do this by cooking for not very long on a high heat, which keeps the inside juicy but the outside browned. This method is good for boneless ... |
Why does eating fried or oily foods give you a sore throat? | Very likely to be acid reflux from the stomach. It's common enough to be occasionally harmless, long-term it can cause permanent damage and may be a sign of something more serious.Not me. Do you notice a difference from specific oils? |
How my neighbor's radon exhaust pipe is not a health concern for me. | I agree with you that your neighbours having a Radon exhaust pipe is absolutely a cause for concern. However, the concern is not that their exhaust may harm you, it is that they have one and you, right next door, do not. It's a sign your local geology means you should be watching out for it building up in your basement... |
. How does the United Kingdom benefit from leaving the European Union? | One of the risks of leaving the EU, is that no one knows what is going to happen because what it means is that since the UK will no longer be part of the union they no longer abide by the EU's rules, and they will need to renegotiate contracts on every interaction with the EU. Trading and Immigration are the big ones. ... |
How come when it's 100 degrees outside it feels really hot to us even though our body temperature is almost 100 degrees at all times? | To add to the other answers, your body has a base metabolism of around 100W - that's energy that's constantly being burned and most of it ends up as waste heat. This'll rise if you're exerting yourself. The result is that your body needs to get rid off this heat or it will cook itself. That's done primarily through rad... |
The concept of wells/underground water. Is there just water everywhere beneath our feet that we can access as long as we dig/drill far enough down? | Wells work by accessing aquifers. Aquifers are not underground lakes, pockets of water, or underground streams. None of those actually exist. Instead, aquifers are usually made of loose or consolidated sand or gravel. There are small spaces between the grains, like in a box filled with marbles, and water fills these ga... |
How do skateboarders not take serious injury when doing an ollie from a height that would injury you otherwise? | Basically, they try to fall on the center of their gravity. For example if they fell from 15 feet they try land in a way that doesn't cause extreme stress on other parts of the body. |
Why in winter, on sunny days its really cold, and cloudy days its warm? | Explain like I'm 5. I'm seeing things on here that 5 year olds wouldn't understand. I'll take a crack at this. Clouds act like a blanket. So the days are warmer when there are clouds. Without clouds the warm air escapes and it gets really cold. That's an ELI5! |
What does it mean to be a carbon based life form? | We are mostly water and stuff like that, but most of the chemistry that happens in our cells that actually does much of anything is all based on structures based on the fact carbon can make super complex molecules. A few other types of atoms can make complex molecules too, and people can imagine life that used them, bu... |
Why do I still need glasses when looking in a mirror? | Because a mirror just reflects the rays of light coming from the object you're trying to focus on, so it's still like looking at it without a mirror. sorry about the shitty explanation |
. Why do communists seem to insist their subjects practice atheism, I thought communism was an economic policy. (Don't get China. ) | To follow up on the other explanations in this thread, China and Russia aren't/weren't communist, they were Marxist. They hoped to achieve communism eventually through other means, right now China is moving away from a socialist style economy to a more capitalist-leaning mixed market, but their justification is capital... |
How does missile "lock-on" work? | A simpler way of looking at radar 'lock' is that normally the radar 'beam' is sweeping back and forth, and maybe up and down, over a very wide area looking for targets. From the point of view a target, the radar sweeps over it slowly, perhaps once per second or two. The target is like _'Yeah, I see you peeping me, I ai... |
why are prices for video games sold by services like Steam so much higher in Australia compared to the United States? | Part of it is history, prices were high so they're still high because people will pay it. Part of it is the added costs of doing special versions of games for the australian market. Part of it is a currency issue - the AUD has shot up in value a LOT in 4 years and other consumer prices haven't fallen to match the USD r... |
What causes people to fall in love? | Similarity in the major histocompatibility complex. If you both stop using scented soap and deodorant and she doesn't take contraceptive pills and you still get the hots for each other, it's game on!", 'Sounds like you where friend-zone slammed hard and are now getting set up for a friend-zone piledriver. |
How a company finds out who is torrenting | In most instances, the methodology for finding who is torrenting copyrighted material is in the form of an anti piracy company - usually a law firm - joining torrent swarms as a 'fake' client, collecting data on which peers are in that swarm. From this, they can aquire the IP address of the torrent client. The next ste... |
why haven't nuclear weapons been used in war again after the USA used two in WWII? | Well, there weren't any world wars since then, for one. And, shortly after WWII, more than one country had nuclear weapons, and therefore there was deterrent to using them. That's really the main reason - we basically had a Cold War with a lot of proxy wars, where both sides had nukes so they didn't want to fight direc... |
If people complain so much about Facebook (layout, privacy issues, etc.), why hasn't anyone created a better alternative? | Google Plus is a much better site. The problem is that everyone is so comfortable with Facebook. Another Redditor said this was like when a new bar opens up, the new bar is awesome but everyone wants to stay at the crappy old bar because it's their crappy old bar. If I can find the comment I'll link it. |
Why do we see such distinct pictures of things when we look at clouds? | What you're referring to is called *Pareidolia* - it's a psychological phenomenon that happens when the brain perceives an object/sound to have familiar patterns that do not actually exist. It's thought to be the result of natural selection and the subsequent evolution of our species: the faster you can identify an obj... |
Why is it pleasurable to stay in bed an extra five minutes? Is there any physical benefit to this? | If you enjoy waking up slowly, you should try a wake-up light. I got one a few years ago and it's the best thing ever. It works like this: you set an alarm and 30 minutes before that it slowly turns on the light. You can program a longer or shorter period for that. It really helps to wake up slowly. I Was very skeptica... |
How are there enough variations for keys that every key in the world can only unlock it's specific lock? | As /u/Hexadecimal_String says, there *are* duplicates. They're just rare. [This article] talks about car keys: > Bob at Bill's Keys in Albuquerque, New Mexico. Bob said how many different keys are possible depends on the automaker. I could hear him tapping on a calculator in the background before he came up with the fi... |
The stuff about relative time in the movie Interstellar. | It's a weird relativity thing. Things aren't separated by space or time, there are events separated by spacetime. And gravity acts on this spacetime, compressing it. Events near large masses take place closer together. Each second on the planet near the black hole takes place closer to one another than each second furt... |
The New Youtube Rules About AdSense that has tubers leaving | I believe it has something to do with copyright management . I know one major source of tension between content producers and Youtube is the way ad revenue is split. |
How would a civilization that does not use money (like in Star Trek) work? | The Incan civilization had no money. _URL_1_ Command economies don't need money, because people interact without free trade. Economies can work without money. The natural economy of human beings is the gift economy, in which people work to compete with eachother as to who can give the best gifts. _URL_0_ Whenever peopl... |
I know this is ELI5, but can people stop moaning about answers having high-school vocabulary words and just use their head a bit? | We'll, at least it doesn't take the name as seriously as [/r/explainlikeImfour]. It could always be worse. I agree with the vocabulary, simply google Define:Whatever, to get a fast simple definition of almost any word, or use the search results when google is unable. |
Hey ELI5, you were in the media! | Wow, that's brilliant, thank you very much for the link, KK! It surprised me to see this, I'll admit, but it shouldn't have. It's now been a day, roughly, and thirty thousand people have subscribed! That's something worth toasting!", 'Like the dot-coms and the housing market, this subreddit is just a bubble and will bu... |
Why does an image get pixelated when I enlarge it. Yet the same image can be put on a huge billboard with no loss of quality? | The image on the billboard may be the same image but at a much higher resolution. You can't enlarge a 125x100 pixel image to much bigger than a few inches without seeing the pixelation, but if the same image was originally at a resolution of 1000s of pixels, you could enlarge it a great deal more. |
Can someone please explain the situation at the Gaza strip? | I can't really explain it like your 5, but besides all that is said below, about the Jewish people coming to what is now known as Israel and basically kicking out everyone else, there is a much larger historical context. So, let's go back to WWI. England, amongst others, was fighting the Germans and their allies. Among... |
Why do erasers fail to fully remove pencil marks? | Paper isn't perfectly smooth it has very small bumps and dips called the tooth. If you press too hard while writing or drawing you flatten out that tooth making your pencil marks into deep valleys that the rubber is too large to get into. Try to practise not pressing so hard when you use the pencil and you will find it... |
Why are there restrictions on liquid containers for planes? I know an attempted terror attack caused it, but how does it make sense? | It does not make sense. It's only in the US, where TSA is a bunch of old guys on a power trip. |
With such a small window of observation, how do we know how stars evolve and age? | I'll add that we've been recording observations about the stars and planets for thousands of years. That's still a short time on a stellar scale but it's not as small as you may have been thinking. |
Why don't cable providers offer 'pay per channel' packages for like $0.80 a channel? | In order to do that they would need to increase the cost of valued channels and decrease the cost of less valued channels and it would be far more than $0.80 per channel. Channels that people really want to watch would be $10-20 a month while others that are less popular would only be a couple dollars. In the end it wo... |
Why are there so many LGBT users on Tumblr? | Wow, we've got some over-explaining here. The answer is really simple. Lesbian, gay, bi and transgender people are small minorities. 1% of women are lesbian and 1.5% are bi, 1.8% of men are gay and 0.4% are bi, 0.1% of men are trans and the number for women is yet lower. If you have a high school class of 500-1000 peop... |
Why do we begin to pick up accents after only being somewhere new for a short period of time | I've always wondered this. Whenever I watch Welcome to Myrtle Manor, I'm stuck with a slightly southern accent for the next hour or so. Maybe I just want to be like them.. |
Why is it that, when you are congested, one nostril is a mucky swamp and one is dry as a bone but then they pull at fast one on you and switch?? | I have been sick with the flu since Thursday and I'm just now coming out of the worst of it. Now feeling like I have a terrible sinus and chest congestion/infection and I came to ELI5 to search for this exact question and you were on the front page before I could search! Thanks! |
Why are soccer player so notorious for faking injuries | We're just in the midst of a phase in football, that's all. As soon as camera assisted decisions become commonplace , it just won't make sense for the players to keep playing these dumb time consuming games. The only thing holding it back is politics And we've seen the positive change that goal line cameras have had. B... |
How do companies like Burt's bees produce bee venom products without killing millions of bees to harvest the venom? | A) [Burt's Bees doesn't make anything with venom in it]. B) While it was once fatal, [we now have nonfatal ways to collect bee venom]. |
Why is the US Oil Industry subsidized by the Government? | First things first, a tax break is not a subsidy. Secondly: It is politically popular and get's you lobbying dollars. No reason for politicians not to. |
Why it's difficult to remember dreams after waking up. | It's an unconfirmed subject, but I'll explain with my knowledge: Your long term memory is basically turned off while you dream. Although you may collect 'samples' or tidbits of your dream, it's most likely very distorted to what actually occurred. Additionally, Your dream is very illogical as it builds off of your ment... |
Why are we not able to make artificial human blood for medical use, or why is it not feasible if we are? | While 'blood substitutes' certainly exist, they're not safe for regular use; haemoglobin *loves* to bond with oxygen, which means that there's almost nothing left to oxygenate the tissues. Free-cell haemoglobin also damages the kidneys, and acts as a vasoconstrictor when it consumes nitric oxide. Researchers have exper... |
If people enjoy playing video games, but find studying boring, why aren't educators reformatting classes into videogame format? | You've never seen an educational game? Most subjects aren't easily condensed into such a medium, though. Even if they were from an educational standpoint, making games requires programmers, artists, musicians, etc - and schools are barely paying teachers as it is.There is a science called gamification and it is being a... |
Why Isn't It A Crime To Simply Be A Member Of An Organization With Known Criminal/Terrorist Activities? For Example: Bloods, Crips, Skinheads, KKK, etc. | The government is obligated to honor freedom of assembly, even with groups such as these. There is a divide between these groups and more actively militant groups, which the government will take action against. If this doesn't make sense, please tell me and I will do my best to clarify. Hope this helps. :)", 'Well, eve... |
When trying to carbon date an ancient man-made object, how do you differentiate between when the object was created and the age of material that was used to create the object? | You can't carbon date iron :) You carbon date carbon. So imagine that you have a kind of carbon which can only be created in a living thing, and that once that living thing dies, this carbon slowly goes away and can't be replaced. Carbon dating measures this left over isotope of Carbon and because we know how long it t... |
If vegetables are healthy for us, why don't many people like them? Shouldn't our body crave the nutrients? | What about societal terms? We see - or at least used to - it often on televion, especially on disney shows geared to kids, the characters getting grossed by vegetables and like. If they never did that, and ate vegetables as if it was totally normal like mashed potatoes, I think our children wouldn't be so resistant. |
why do we have finger and toe nails? | You have fingernails so you can pick your nose. You have toenails so you can pick your friend's nose.Wait, when did we start cutting our nails? Did they just wear down at the same rate they grew before that or did the romans have super long nails?To provide a backing to your finger tips to help you grip better. Also ev... |
What's the deal with Chemtrails? | It's basically just fog/condensation from the exhaust of airline jets. The air high up is cold and dense, where the heat from the airline jets is hot and sparse, creating a trail of essentially fog that appears as a cloud. Kind of like breathing in cold air just on a bigger scale |
Is there an actual not racist reason basketball is largely made up of people who are black? | Ugh, this question encapsulates what is wrong with this overly PC movement going on in the U.S. It is not racist to point out the fact that there are differences between races. African Americans are better athletes in general due to genetics. Not racist. Fact. Also, it's a huge sport in their communities in general. I'... |
why are there no plus-sized male models? | Maybe, and I'm just throwing this out there, not a lot of people want to stare at a ~~fat~~ *plus-sized* male model? |
What exactly do Pluto and Charon orbit? | Every planet and it's moon, as well as every planet-moon system and the sun orbit orbit around a point like this. Let me explain. Pluto and charon are relatively close in mass . That means that not only does pluto have a significant gravitational pull on charon, but charon has a significant pull on pluto as well. The r... |
Why is bottled water so expensive when it's something we can get free from our taps? | because they can, if you can get someone to pay 4 bucks for something that costs you a couple pennies you'd be a fool not to |
What can a hacker get from exploiting my laptop's camera? | It's exceptionally unlikely they would gain any useful information against you. Furthermore, they don't care about you. It's a different kettle of fish when you talk about celebrities like Mark Zuckerberg. People would love to spy on his comings and goings. And business webcams could be a source of leaked corporate int... |
How do Methamphetamine manufacturers routinely blow themselves up? | Many of the chemicals used to make meth are highly flammable. And most of the typical 'urban' manufacturers are making the meth in poorly ventilated locations. Combine this with open sources of heat such as a stove or maybe a water heater and you get your explosion. |
Why do police body cams have such bad quality when camera's like gopro's are so cheap? | Everyone has been discussing technical limitations however the likely answer is actually much worse. There are plenty of cameras with much better video quality available. When a municipality or county needs to buy something over a set dollar amount usually a couple thousand they have to go to competitive bid. Here they... |
Why do most American college and universities require SAT and or ACT scores? | They are called standardized tests. Meaning it is to show how everyone is ranked in a different sense. They do it because different schools can have different difficulties. Someone earning a 3.0 at one school might of had a harder time than someone that got a 3.4 at a different school. Because teachers/schools look bet... |
Why are there different power companies but only one power grid? | > I live in Texas where there is a statewide electric grid that covers Texas and only Texas. However there are several different electricity companies such as Relient and Texas-New Mexico Power Company and others. What exactly do these companies do? If they all provide the exact same electricity then why do there rates... |
How do scientists delete or manipulate genes? | Don't know if there's a LY5 answer. Researchers essentially trick the replication machinery into not making the part they don't want. Or tricks it into making stuff that wasn't there before. |
Why does meth make users skin so ugly and old-looking? | It has less to do with what Meth itself does and more to do with what a user of meth does while abusing it.Abusing meth, a stimulant, tends to make the user less apt to take proper care of themselves. Heavy meth users go days without food for example. Usually, because the user is more concerned about finding their next... |
Is there a reason why some people with Tourettes have swear words specifically as their tick? Of all words that could be their tick, why is it almost always profanity? | It isn't almost always profanity. Actually it almost always isn't. You just remember people yelling swear words for obvious reasons. The most common manifestation of Tourettes would probably be jumping in place or obsessive blinking |
The point of using Marijuana. (Aside from medical reasons) | I use it exclusively when I play live music. It has several benefits for me, and these are not necessarily true for other musicians: it lowers inhibitions - being tense or self conscious when performing just kills things for me. It starts a spiral of nervousness and shame that makes me perform considerably worse, becau... |
How did the world operate before alarm clocks? | Another way was that Native Americans would drink a good amount of water so they'd wake up earlier than they would have more naturally", 'Before electric lighting, most people would go to bed with the sunset and wake with the sunrise. |
If the "reddit hug of death" exists, how come it doesn't happen to reddit itself? | this is actually a pretty big problem for *any* website with a ton of users. At some point a server will just fail. So generally these websites mirror themselves onto many servers and rotate the IP's in the dns tables so that there isn't a single IP serving the entire internet.
