Is 'Race' a scientifically accurate term to use, given humans have only one species and there are no taxonomic differences amongst them? | A lot of these answers are really not eli5, more like eli_verysmart. I consider myself about as bright as a five year old, let's give it a whirl. Disclaimer, I'm not a biologist. I just play one on the internet. Let's step back from humans for a second and look at another example, dogs. Dogs are an animal species, or r... |
Why are cockroaches so hard to kill? | Compressed body form, when you say hard to kill I'm assuming your talking about squishing. A roach can flatten out like a piece of paper and get into crevices or slip into something tight. So when you stomp I think the object used isn't always rigid flat and the roach survives in the space or flattens enough to dampen ... |
Landfill. Surely it's a really really bad idea to fill holes with a partly rotting, gassy, mix of crap? Won't we run out of places to put it? | No, it's a reasonable way to dispose of solid waste. There is far more land than is needed to support solid waste disposal for hundreds of thousands of years.The landfills here get filled over and then holes drilled in to the rubbish. Then they put pipes coming vertically out of the rubbish to vent the gas. So I suppos... |
How or where do radio stations get their music? | For several weeks now my buddy has had a two hour radio show every Saturday on an independent radio station. It's his responsibility to find and purchase the music to play on air and online. This is obviously very different from your standard Clear Channel broadcasting. |
Can watch HD porn but EVERYTHING else buffers | Basically, the porn industry created broadband and fast streaming. Streaming porn was available years before YouTube or any other video streaming service.

Are the giant LED panels on every tough guy's pickup truck just the equivalent of a rack of roof beams, or is it something else? | When I work as a welder's helper we can be on the road 4 hours before the sun comes up. Driving on shitty oilfield roads is a lot safer when you can see farther up the road and anticipate hazards. These lights make a huge difference. |
If there's only so much gold available in the world, why does Goldschlager and edible gold flakes for baked goods exist. Aren't we depleting our supply? | Are you asking why aren't there laws that make it illegal for private use/ownership of gold? I'd point out, there's only so much of *anything* in the world. Land, iron, food, water, anything. |
Why did car trips seem so long when I was a kid? | As a child you are small, so traveling long distances are longer compared to yourself. Imagine the length between steps when a 5 year old is walking, and then compare it to that of a 20 year old's. |
How close is the reproduction of classical music (Mozart, Beethoven etc) we hear today is to that of the actual music composed ? | It's kind of impossible to know anything about what classical music sounded like before the advent of recording technology because interpretation style is subject to perpetually changing fashion. Even within our own lifetimes normative classical music interpretation styles have changed so radically that we sometimes fi... |
Why aren't urinals shaped better to prevent splashing? | In the army out towards Iran we pissed in pvc tubes hammered into the sand. Seemed to work fine. Never pissed on my own dick if I remember right. Shit in sandwich bags, Wagbags, aptly named for when you move them from seat to destination, and burned them in a pit filled with ashes of old breakfasts n dinner wagbags, pr... |
The psychology behind a mother blaming her child when said child is being molested/raped by the mother's husband. | Children, the elderly, and the mentally disabled are easy targets to blame for anything because they have little force of persuasion over others. Some people make up their own reality and when able to will tell lies, and manipulate or coerce others into accepting responsibility for things or bad treatment that they don... |
How do modern socialist states deal with the 'free rider' problem? | There are no modern socialist states. If you mean social democracies, they don't need to. The monthly check you get is less than any job you could get. You can live off it, sure. But some of the incentivizing children for the US's welfare queens doesn't really factor in because of the social democracy's systemic approa... |
Why couldnt general Grievous use the force? was he a sith or just a regular cyborg alien who learned lightsaber combat? | Too bad all those enhanced mental processes didn't help him think of interesting dialog in the movie.When I played The Force Unleashed, it said the Emperors Guard,the guys in red, had some use of the force. I dont understand how .. |
Why are movies sometimes released on Christmas Day? Wouldn't that lead to lower amounts of money? | I used to work at a movie theater. Christmas morning we'd have a small handful of customers. Come the afternoon or evening shows and all the people show up. Several sellout shows and is one of the busiest days of the year. Thanksgiving being the next busiest I believe. The night shows would have similar attendance to t... |
How can old films be remastered in 4K while digital video cannot? | Digital video is made up of pixels, it's a fixed resolution. Many movies today are only 2K, 2048×858 and 1998×1080 . Film is analog, no resolution. 35mm has a rough digital equivalent to 4K. 70mm IMAX like Interstellar have a digital equivalent of 14K-18K, or ~135 megapixels to 225 megapixels. |
When collecting DNA from saliva or a cheek swab, how do they know they aren't looking at the DNA from bacteria or bits of food in our mouth? | Because human DNA can be distinguished from non-human DNA. Humans have 46 chromosomes arranged in pairs while bacteria usually have 1 or 2. The chromosome pairs are also arranged in a way that are unique to humans so even if you took a sample from something else with 23 chromosome pairs it still wouldn't look like huma... |
How Can I Unlock The Front Door To The Apartment Block Where I Live With The Same Key I Use To Unlock My Apartment Door? | It's known as a maison key system. You know how the janitor at school can open all the classrooms with one master key? That means that 2 keys work for a particular classroom door: the teacher's key and the janitor's master key. The same idea applies with the apartment gate, except with possibly dozens of keys that work... |

Why do we use pillows? Babies/infants/toddlers seem to do just fine without them. What happens, causing us to eventually need to sleep with a pillow? | I don't sleep with pillows. I inevitably end up shoving them away after too long if I try. I like to just be flat on the bed. |

I'm colourblind but I see blue/black.I see black and blue. OP send us a different picture of what you see as absolute black and blue. |
Why hasn't a North Korean attempted to assassinate Kim Jong Un yet? | North Korea isn't bad because the leader is bad. It is a horrible place to live because of the Government. If you were to kill Kim Jong Un he would only be replaced by someone just as bad, perhaps worse. Besides, most North Korean's think of their leader as an almost godlike figure. They are told that the rest of the w... |
How do we know that a note is not part of the scale? | It's because you are used to hearing notes in that kind of scale. As you grow up you hear music which is built on the same kind of rules as the music you're playing on your saxophone.

Why do humans have such a horrible sense of smell? | The way I understand it, we as humans don't really rely on our sense of smell for anything extremely important since we have our other senses that do the majority of the work.

Why So many people on reddit hold negative views towards China? | There is the pollution. There are the jobs that left the US and went over there because labor is cheap and environmental laws are lax. The companies there tend to copy our stuff and undercut the prices of locally made products. There is the way they treat Tibet. They prop up North Korea and don't do anything obvious to... |
How can being homeless be made a crime? | This is a hard question. For me, I was homeless for three years, but I tried everything I could to get a job, get a place of my own, and get on my feet. I went from shelter to delete shelter, and sometimes lived in my car or camping in a public park. However, what I noticed while being homeless is that I was a rare ind... |
When we're trying to fall asleep, why do we fidget? | since the question has been answered, I'll just give helpful advice. If you want to fidget less, clench all the muscles in your body at hard as you can until just before it starts to hurt, and then release them.

How do anti-bacterial hand gels/soaps kill bacterial cells but not your own cells? | Skin cells and bacteria cells are built very differently. Because of that chemicals in soap are mostly harmless to us and dangerous to bacteria. Because bacteria cells are much more fragile it doesn't take much to disrupt their inner workings. |
How is it possible to have dreams where we believe in completely impossible things until we wake up? | Here's another way to see it: You indiscriminately believe whatever you see. If you're dreaming, you just believe it's real. If you're awake, you take that as reality instead. Really we just automatically take anything we see for reality. If you woke up suddenly as another person with their memories and their surroundi... |
Why was it easy to learn a language when I was younger, but now it is difficult to learn any new language as an adult? | I believe this is a myth; it seems counter-intuitive, but language acquisition is easier when you already have knowledge of grammar, sentence structure, etc. . |
Why, in North America, is diesel more expensive than gasoline? I just learned that in Europe gasoline is more expensive than diesel. | 14 years ago it was subsidized by the gov't and was cheaper than gasoline. When gas prices started to spike from under $2/ gallon to $4/ gallon, diesel bumped up.higher than gasoline, as it should've bc diesel fuel cost more to produce than gasoline. Asian governments and European gov'ts still subsidize diesel bc tbe t... |
Why are juggalos so hated on reddit (and in general), when female prostitution is viewed as for the most part completely acceptable? | this is the greatest reddit post of all time. OP is either a genius, or the complete opposite of a genius but this is the greatest thing i've ever seen on reddit. |
Why are many trains not designed very aerodynamically? | [Bullet trains] are aerodynamically designed but I think you're talking about regular trains. They did try to make regular trains sleeker in the 1930s [like this] but the efficiency gains were offput by how much harder it was to maintain them. So for regular trains how aerodynamic it is isn't the ultimate factor. |

That way patients that can use the drug without the stoner stigma. | There are already a number of drugs on the market related to THC.

why are sportspeople more likely to get injured now compared to decades ago? | Several factors: 1. In the NFL guys would play with non-obvious injuries. Concussions in particular, but also strained muscles and lots of things that can only be diagnosed with MRI. 2. In baseball, pitchers throw harder than ever.

Why famous people seem to date and marry other famous people. | Famous people tend to be in the same social circles as other famous people. Just like high school kids tend to date other kids from the same school, famous people tend to date the people they're around. |
- when people cut people open in surgey, why dont they bleed everywhere? | Can someone ELI5 why deleting comments is somehow better than posting comments with big words like 'cauterize'? If a comment is too complicated, reply comments can be less complicated - while still retaining the meaning of the original, informative comment. For instance, I'm no surgeon, but I'm good at explaining thing... |
what do hard drugs do that cause a permanent change to a person's looks. | Meth makes people feel like there's little insects crawling inside their skin, causing them to constantly scratch their face and make giant, bleeding holes in themselves.If you're addicted, I think "getting your fix" becomes priority one, even in front of basic hygienic standards.Doesn't meth make people grind their te... |

Why have humans not returned to the moon since 1972? | Cuz been there done that! Actually though. We have been there and seen all there is to see as far as our scientists are concerned. It's an expensive trip to make just to go there for the sake of going there. Unless there's any scientific benefit to earth or the country that's funding the mission there's no point in fun... |
Why aren't women required to register for Selective Service in the US? | Because the last time the draft was active women weren't allowed to serve in combat roles, which is what most draftees we used for. No one's too concerned about changing the rules because no meaningful amount of people have supported reinstating the draft in the last 30+ years. |
why do we get grumpier the more tired we are? | Basically yes, you run out of happy juice. I'm no expert in this field but basically as you get tired stress hormones begin building up in your system. Get enough of these and you get side effects, irritability being one. Theres a few different hormones but one of the big ones is cortisol I believe. Do this regularly a... |
Why are people against GMO's, Isn't every plant genetically modified? | I can't speak for every body on this topic, but I don't have a problem with GMOs. What I **do** have a problem with is all of the lobbying and political manipulation done so that the average consumer can't *know* if something is genetically modified. If GMOs aren't bad for us, why put a fuck ton of money in the lobbyis... |
Why are so many famous songs targeted at pre-teen girls? | Puberty and new emotions. This makes them an easy target for emotional pop songs about feeling upset over boys as they are chemically wired to react to this.Same reason 12-16 year old boys corner the metal market wired for agression. Parents will buy their kids their favorite album, which is basically an emotional supp... |
How the first human beings were able to translate from one language to another. | They're called pidgin languages _URL_0_ They usually start when a trader moving along the coast stops to trade with locals and there's no common tongue. You point to your mouth, then hold up some fancy thing you want to trade. Eventually a few words will become obvious, then an ad hoc grammar can develop. A couple doze... |
Why do so many games now not have local LAN? Is it hard to implement? | B/C the proportion of the user base that would use it is so small that it isn't worth allotting the time necessary to code it. Other features are more important so lan usually just gets chopped from the feature set. |
How will self-driving cars be able to determine the amount of friction there is on the surface of roads? | It should be no problem to figure out the friction of whatever surface you are driving on since you know how much your motor is working and how fast your tires are actually turning. I don't know though how they will be able to predict the surface properties of the road ahead of them. |
how long are skyscrapers built to last? If they are too old and needs to be put down, how will they be demolished? | It's estimated that without any repairs or maintenance, most skyscrapers would collapse after about 100-200 years. Now, they certainly can perform the repairs and maintenance and keep them up indefinitely. I don't know if a really huge skyscraper ever has been demolished. I'd imagine they'd use cranes and stuff to slow... |
Why is it that video games have loading screens after deaths? | Because, at the risk of making this sound political, naïve death systems that go through the same code path as loading are super easy to make, and well-designed death systems that squeeze out every drop of performance are hard. Every team competent enough to make a triple-a game _could_ make a loading system like the l... |
What should I not point my laser pointer at and why? | Not sure if someone has mentioned this yet, but don't point a laser into a DSLR camera, they can burn the sensor and all pictures taken after you've burned the sensor will have some kind of dot or line that cuts through the image. You can YouTube DSLR and lasers, and IIRC there's a video of a guy that used his DSLR at ... |
Why the Democratic party demanding Romney's tax documents is different than the Republican demanding Obama's birth certificate. | Not too many presidents probably get called out on their birth certificate, and so Obama provided the short form and didn't want to do anything further. I am fairly sure there is not a precedent for providing a long form birth certificate, but I could be wrong. So only people with an axe to grind really pushed for the ... |
Why do we need to test our smoke detectors, and how exactly does the test button work? | The battery can fail, or some other circuitry might go bad over time. While they don't give any active indication that they are working, they're still suffering wear and tear, as monitoring for smoke/carbon monoxide is a 24/7 operation. Smoke detectors can break just like any other electric device. We test them regular... |
Why is there ice in some urinals? | Sometimes it's just old ice dumped in there", 'They say to throw clothes or shoes in the freezer so the cold temperature kills the smelly bacteria, for a quick fix. Seems like a good way to reduce the urine smell in urinals by dumping ice in themdrunk people will focus on melting ice instead of just randomly pissingSom... |
Why do so many people think prostitution is bad? | It's basically not very high on most people's laundry-list of social changes desired and no politician is going to come within 1000 feet of any pro-prostitution legislation if they don't have to. |
How do dogs interpret human language? | I would imagine it's alot like talking a someone who only speaks Spanish and you speak English. It just sounds like jibber jabber but eventually you understand a word here or there. |
Why humans are attracted to butts and why we find them sexually desirable? | Men tend to be attracted to the look of secondary sexual characteristics, i.e. feminine curves.

Most animals have sex in doggystyle position, so our ancestors were probably originally mainly tu... |
Why does the Korean War get much less attention in history and modern culture than other wars? | It is because the scale of the conflict was small in relation to WWII a much bigger conflict which happened only a few years prior. People from the nations which made up the task force which went there were tired of war and therefore it wasn't mentioned much on the much tighter controlled media at the time. . Much bigg... |
When I have an overwhelmingly familiar dream, have I actually dreamed it before, or does it simply feel "familiar" because my brain knows what's going to happen next? | I dreamed same, or at least almost identical dreams a few times. A dream journal helps, if you're not sure whether you dreamed this before or not. |
Why does a good pair of headphones/earphones make it feel like the sound is coming from inside the middle of your head? | They don't. GOOD headphones try to reproduce the neutral sound of flat speakers as best as possible, including making it sound like the audio is coming from around you rather than inside your head. |
Why is vinyl considered the gold standard for music quality? | I digitized my vinyl collection. The clicks, pops and skips are like old friends. When I hear the same song without them, it's mildly disturbing. Vinyl sucks |
Why is PETA considered evil? | So one of the biggest complaints is that they [euthanize a shit ton of animals]. That seems a little hypocritical considering how much PETA claims to care about animals. They [try to justify it] by saying that they're euthanizing animals in terrible shape. But the reality is that there are plenty of no-kill shelters ou... |
How do sugar substitutes, like saccharine, taste sweet but have no calories like a true carbohydrate? | Some things that are listed as zero calorie actually have calories, but if there's less than 5 per serving size then they are allowed to round down to 0. Others do have calories, but the body burns more calories digesting them, essentially making them like a negative. Many artificial sweeteners are very similar to suga... |
How does Samsung and Apple release updates that "increase system peformance" if they cannot physically take each phone and change the Processors, Ram etc..? | It's like how console games released near the end of the consoles generation look so much better than the launch titles. The console didn't get better, the programmers just figured out better tricks to maximize the return from the system. |
American here - what does 'o levels' and 'a levels' mean? | Wait, does that mean that British kids only have to go to school until they're 16, if they don't want to go to college? And they can still get a good job in some trade, without the stigma of a US high school dropout?", 'O levels no longer exist. they were replaced by GCSEs primary school until age 11 > secondary school... |
Confused Canadian - How do I shower in Europe? | In England here, every shower in buildings I've lived in has had a curtain. I find the fully enclosed kind to be kind of claustrophobic |
Why is ISIS such a threat that needs worldwide intervention, when similar movements (Kmher Rouge, Bhurma) were allowed fizzle themselves out over the decades. | The answers given here are only half right. The main and foremost reason that ISIS is being attacked is that **there is no superpower backing up ISIS.** Is there was then ISIS wouldn't be attacked. Also ISIS is not a nation but an organization ISIS has no right to self-determination. |
Why does water act as hard as concrete if you land on it after jumping from a high enough point? | Water cushions a fall because it moves out of the way when you hit it, but not too quickly, which slows you down over a longer period of time than if you hit something solid. Since water doesn't compress much when you hit it, it only cushions your fall by slowing you as it moves out of the way- unlike, say, an airbag, ... |
Why does staring into bright lights help me sneeze? | It is because the sun's ultraviolet rays irritate the sensors in your nose, and you want to get it out", 'I know ucsf is doing a study on it. I have it too, very refreshing. |
What are the best tactics for monopoly? | Don't just buy everything. Get the railroads. Get the utilities if you can, but never at full price. Houses/hotels are the way to win -- if you can't get a complete set so that you can start building those, you're going to lose. Make sure everyone uses the rules and that free parking doesn't give you money somehow or t... |
Why were there ever 13 colonies instead of just one "British North America"? | Also, religious differences between the colonists made it difficult for them to get along with each other, it's easier if you just separate them under different governments. The Mayflower pilgrims founded Massachusetts , but they kept excommunicating each other for failing to be sufficiently Puritan, and those breakawa... |
How do companies find, choose, and start using a sweatshop? | Obviously I don't have any experience in the field, but I can imagine. So here is my guess. A tech giant advertises that it is looking for manufacturers to produce their product and they will take the cheapest option. Someone says I'll do it for half of what the lowest option you get is. The company agrees of course be... |
What do people mean when they say "I can understand X language, but I can't speak it"? | Think about when you're reading, and you come across a text with a lot of words you don't know, but you can figure out what's being said from the context and the words you do know. You're not going to turn around and use those words in conversation because you don't know the words well enough to recall them or use them... |
Why can't we improve the hardware of consoles such as playstation or xbox like we can with pc's? | because they aren't designed to be upgraded plain and simple. the console manufacturers don't want users messing with their hardware because it can only cause problems. |
Why do we taste eye drops after inserting them? | This is because of their lacrimal punctum. Go to the mirror and pull your eye down and look at the red bit near your nose, you see the hole? That's it. When you produce tears or have another liquid in your eyes, some of it drains into these holes and then into the lacrimal sac, the nasolacrimal duct, and eventually int... |
why do most canned fruits taste essentially like their fresh counterparts, but peaches taste completely different? | I'm not sure if this has an effect on the flavor, but [the canning process makes canned peaches at least as nutritious as fresh peaches], and sometimes more. > Researchers found almost four times more [vitamin C] in canned than fresh peaches. In addition, canned had comparable levels of vitamin E and a lot more folate ... |
Why does methamphetamine use ruin your teeth? | If you've taken Sudafed before, you've probably noticed a dry mouth feeling as well as your sinuses expanding due to reduced blood flow.

Why does it take so long to withdraw the US' troops from the Afghanistan, Iraq, and the other countries they're in? | Because you don't just walk into someone's house, break their vase, and then walk right back out. You try to fix the vase. |
Hows is the Commission on Presidential Debates legal? | Because political parties aren't part of government. It might seem like they are, but they are really just private clubs who decide to support certain candidates over other candidates. If two private clubs want to allow a third club to set up a debate, that is nobody's business but theirs.Of course it is legal. There i... |
Why do smokers get a calming response from cigarettes when they are distressed, nervous, or anxious; when it seems like nicotine (a stimulant) should have the opposite effect? | Part of addiction is Pavlov's good ol' classical conditioning. The more you use a drug in a predictable way, the more your body learns to predict your drug use. For example, if you take a heart rate stimulant every night at 8pm, then eventually by 7pm on following days you might start finding yourself with a decreased ... |
What it feels like to be stabbed. | I tried to break up a bar fight a few years back and got stabbed 3 times in the abdomen for my trouble. At first I felt nothing , but then after I looked down and realized I had holes in me there was a dull ache. The guy got me down the right side of my torso so it was really just fat + muscle, he didn't hit anything m... |
How can companies like Amazon go so many years without turning a profit? | As long as investors think you will at some point make a huge win, they will invest in you, pumping fresh money in, hoping for that one big win that they then will share. It's a gamble. You bet on the company making profit in the future. If they do, you win, if not your money is lost.They reinvest most of their profit ... |
Why was Mr Netanyahu's speech so popular in congress? Why is he so popular regardless of the controversy coming from POTUS? | Obama is attempting to normalize relations with Iran. Normalized relations with Iran means that Israel, foreign-policy wise, becomes less important to the US. The Democrats have slowly drifted away from their support of Israel over the past two decades and, while the Democrats support is still there, Israeli leadership... |
why does the U.S. refrigerate eggs when most of the world doesn't? | You have two choices when it comes to preparing eggs for sale. You can produce the eggs in clean condition by caring for the chickens and having clean coops. This allows the eggs to be packed and sold with no further cleaning required. In that case it's best not to refrigerate them because refrigerating them will cause... |
How are those ships put inside bottles? | If you buy one at a gift shop or store, it's likely that the bottle was assembled around the ship. A ship is created. A bottle is made, missing either the top or bottom. The ship is placed in the bottle. The bottle pieces are reattached and glued/melted back together. You see this most often on bottles that have decora... |
What exactly is your body doing during sleep to generate/recover energy for use the next day? | The purpose of sleep isn't to recover energy per se, rather it's a state of general recovery for the entire organism in question. To briefly clarify, your body can't 'generate' energy at all, rather we ingest energy and convert that to other forms of energy as needed. For example, we convert chemical energy to kinetic ... |
Why do we need REM? Why could't we just close our eyes and dream? | Cause they were a great band man, and their songs HELP us dream! C'mon! What's the Frequency, Kenneth??? You know what I mean?", 'Do I understand that your question is "Why do your eyes need to move?" Well, that's a question that has intrigues scientists for years. For a while, we just thought that it was just that our... |

How does non-scratch glass work? | The latest versions aren't normal glass, they're artificial sapphire, which is very, very hard. You can scratch it with diamond but your keys have no chance. |
Back in the 90s there were a few vehicles that came out with 4 wheel steering. Why didn't this become a thing? | I know the GM trucks that had Quadrasteer weren't that popular. It was an expensive option and most people who tow trailers have learned how to back up with normal steering. I would assume the cost and potential breakage were problems in other cars. |
