Why is it so satisfying to argue with people on the internet who you'll never ever actually meet? | I think it's because some people on the internet are just horrendously *wrong* about some things.

I often end up providing sources to rebut idiotic claims I suppose the rea... |
How can people not be in a "gender binary" | The issue here is that the phrase 'biological gender' makes no sense.

There are numerous cultures in which there is a recognised third gender - people ... |

Heavy drinkers require more alcohol to reach 0.1 BAC. They *also* are les... |

Why do teachers assign "odds" or "evens" assignments? | well, sometimes books have the answers to one set in the back of the book, but aside from that, a chapter has multiple sections with different types of problems, so instead of picking out 10 questions out of each of 4 different sections, they just simplify it and say just do the odd/even. plus, in a given section they ... |

What exactly happened to make Julian Assange and Wikileaks go from loved to hated? | Well, for one thing, in recent times they have been very selective in the information they distribute, all of which seems to further the political agenda of Putin, so they've lost the mantle of impartiality they had maybe 5 years ago. Questions like why you would leak the DNC information and not the RNC info just screa... |
why can't we take all the money being spent in court fighting over voter ID and just ISSUE everyone a free ID. | It's not about the cost of having IDs. It's about the process of applying for one, waiting in line during work hours, and about certain political figures suppressing the votes of individuals who are unable to obtain IDs due to time and money constraints. They don't want them to vote, so they're using this as a way to p... |
could you survive falling out of a plane, using nothing but an inflatable life raft, like in Temple of Doom? | Jumping out of a plane full stop is survivable. Terminal Velocity isn't an absolute death sentence. It's very bad of course, but there have been recorded cases of survivors, if they landed in snow or something soft. In this particular instance, the raft would increase surface area, slowing down the speed of terminal ve... |
Why is bacon sold in strips, instead of slabs, like steak or ham is? | Bacon is sold in slices for the same reason bread is: people find it convenient. However, as people have already mentioned here it *is* sold in slabs as well . It's a matter of marketing towards different types of buyers. The people who prioritize convenience over flavor will go for the sliced while more picky buyers w... |
Why can i carry a concealed gun to protect myself, but I can't carry brass knuckles or a switch blade? | Guns have serial numbers that can be tracked through the National Crime Information Center , which is what U.S.A. law enforcement uses when they encounter a suspect's firearm, gun of unknown origin, or when a gun is reported stolen. My guess is that knives and brass knuckles are infinitely harder to track, and easier f... |
How do I know that people see and taste things the same as me? | I have a friend who is colour blind, and apparently no one realised this until he started drawing yellow trees and so on at school. Also I used to work with a colour blind guy and he used to buy clothes before work and bring em in, and then check with me what colours he had actually bought. In this sense then, it's jus... |
Why does LASIK eye surgery cost so much and why isn't the price affected by the free market? | When laser eye surgery first came about is was thousands of dollars.

How can the US switch to instant runoff voting? | The main difficulty in adopting IRV is that both of the Big Two parties are strongly opposed to it, since it lessens their power.

Were our teeth naturally supposed to be yellow? And is it actually healthy for them to be white? | And isn't it a slight flaw, from an evolutionary perspective, that we need to brush our teeth every day to avoid dental problems when we lived thousands of years without doing so?

Whatever falls into the hole in which you shit is not something you... |
On D-Day the allies came in on boats, why didn't the fly airstrikes and clear the area out first? | They did. With 100's or aircraft, and then with ships of all kinds bombarding. But beach defenses are relatively small, and well concealed, or well armored.

How do budget airlines make money? Do they make more money than premium airlines? | The main difference is they cherry pick the most profitable routes out of the cheapest airports.

How do people get Aspegers? | Saying it can be removed isn't quite how I'd put it. You can learn to overcome some of its aspects, but it's not always easy. You can also learn to hide some of the effects, which isn't the same as overcoming them, but again that's not always easy or possible. |
Why does it take longer to copy 1GB worth of small files than it does to copy one 1GB file? | Every file has metadata -- information about the information. Things like the file name, creation date basic directory information, and things like where on the disk that it's located.

What motivates criminals to commit certain crimes that could have their freedom taken away for the next 5+ years? Is it a psychological difference between crime concious people or a hope they never get caught? | In this case I can only assume he is an idiot who didn't realize you do not joke about such things. Just because he has no history of mental illness doesn't mean that he isn't in the early stages of something or has been successfully hiding it for a while. As for criminals in general I am sure there are many factors as... |
Why does Israel, a high security country, have such a seemingly insecure passport? | It's a different type of security. Israel doesn't have an immigration problem like US or Australia, so there was never a real need for this kind of measures or a justification for the high cost of switching to it. If you're thinking of terrorists - most of the local ones have an Israeli ID of some sort anyway, be it an... |
Why is it that a "not guilty" verdict cannot be appealed, but a "guilty" verdict can? | It's a constitutional protection against government abuse.

Or they could punish someone by taking them to trial over and over until they are emo... |

-- Why are obvious jokes posted about school shootings taken legally serious while rape and death threats are largely ignored? | LOL" and "to see if I get arrested" make things obvious jokes.

How do authors like Danielle Steele, Nora Roberts publish so many novels while other great authors have only written a few? | Some are just prolific writers, others one they reach a certain level of success are able to hire assistants and co-authors or ghost writers.

what exactly are DJs such as Skrillex and Deadmau5 doing when they perform live besides just playing the songs from their album? | I believe that the main idea is not the live performance of the band. It's the atmosphere, the people, the experience of thousands of people coming together and looking silly while dancing! People go freaking loony at these things! It's quite the thrill. You just can't get the same feel from an iPod. |
How a site can display something in place of an ad that says "You are blocking our add and this hurts us" instead of just posting the ad | The advertisements are not controlled by them. They are given a script that links to a third party which controls what you see in that space. That's also how they know when someone has viewed it or clicked on it. If you block scripts, the third party is removed from the equation entirely and website owner doesn't get p... |
Do regional accents serve a purpose? | Phonologist here. Finally a chance to chime in on something I know a little bit about. /u/robexib is absolutely correct that accents are not genetic and are a reflection of local culture.

Why are snowflakes supposed to be unique? | Snowflake crystals start off as a very *tiny* crystal seed, which expands into a snowflake. **Any** small change in the crystal seed such as pressure, temperature, or shape means the snowflake will be dramatically different.

Why is it better to have income tax % go up by bracket instead imposing a flat tax. | This kind of system is called a progressive taxation system. It's meant to tax the rich more than the poor. Some of the reasons for this are: * It's a form of welfare for those in the lower tax brackets * It causes less of a total burden on people as a whole, as those most able to pay taxes pay the most * It offsets ot... |
Why does the US government feel the need to have such a high military budget when it seems every other field doesn't have enough funding? | The US military budget isn't just for the US military. The US military provides an umbrella for all American Allies. Many US allies have very small armies knowing that if they are forced into a war they will have the US to have their backs.

What are bayesian networks? | Not exactly an expert myself, but here's my understanding. A Bayesian network is like a map.

If you're currently living in Florida, then where are you going to mo... |
Why i'm (USA) being forced to have health insurance. | Because it's good for everyone if everyone has health insurance. You are included in everyone, therefore it is good for you on average.

Which ones have you played? |
Can a plane flown by air traffic control? If not, why? | If we started doing this, I'd imagine hijackings would just occur at the control tower and be more difficult to stop. If we're using it to stop hijackings, then there must be some sort of mechanism to make the cockpit controls useless, and transfer all control to the control tower. This mechanism would have to be absol... |
Why does adblock only block some ads but not others? | Adblock, as far as I know, recognizes code designed for ads . If an ad's specific code has not been added to Adblock, it won't recognize it as an ad, but rather an actual part of the website, thus not hiding it. It is the same reason why you must update your antivirus database, to add new viruses to look for. Tl;dr: ad... |
why are there so many more calories in restaurant food than food I make at home? | People who won't eat at restaurants because they are unhealthful will, when they cook for themselves, probably cook more healthfully.

How does the brain store memories, and how are we able to remember things after having not thought about them for years? | Right now our best understanding of this is the creation of networks of brain cells.

The links are not permanent which is why you can forget or why you remember things that haven't happened/ h... |

Dogs lick themselves too, but they generally need to be washed or else they get smelly. | I don't know but it's one of the main reasons I like cats more.

Why do schools still suspend kids when its usually pretty clear they don't want to be at school in the first place? | Practically, the biggest reason is that for students that require suspension, schools lack the necessary means to encourage acceptable behavior, unlike parents.

Why are Amarican car gas tanks mostly on the left but some cars have gas tanks in the right side? | I think it's for convenience. Most of the right side gas tank cars are probably also available in right hand drive, so that when you exit the driver's side, the gas cap is conveniently right there.Just a quick fact if you are ever unsure on what side the tank is on, the little fuel bowser on the dash has a nozzle that ... |
Why do general relativity and quantum mechanics not play well with each other and how are theoretical physicists going about discovering a "theory of everything"? | General Relativity mathematically describes the force of gravity very accurately, so accurately in fact as to have predicted the recently discovered Gravitational Waves a century ago. Quantum Field Theory mathematically describes *everything else* very accurately. So accurately in fact that its models - such as the [St... |
How do all the individual cells in our immune system communicate and know when to start fighting off an infection? | There are lots of different signaling molecules called cytokines that help to regulate the immune system.

Some of these cytokines even have antimicrobial properties themselves and directly at... |
Why do movies and TV shows insist that every electronic device make noise when interacted with? | I'm sure someone who is educated in film will correct me but: It's a way to communicate interactivity to the viewer. If you imagine a scene where two characters are talking and the camera is between them so character A is on the left side of the screen and character B is on the right. If character A was to pull out his... |
Why are most dogs/cats completely uninterested by television? | I don't know about you, but whenever my dog sees another dog that looks like it may be trying to do harm on tv he goes ape shit. |

How did the modern playground came to be? When did a swing set, a slide, a seesaw and so on become the standard? | I was in an Egyptian Nun-Run French Catholic playgroup in the 1950's. We had all these things there, and 'Alouette, chantez-Alouette', while the rather nice, fierce, trim, little French girls did things on see-saws and swings. What an influence on 5-year-old male British minds! Pity we can't all still be friends? - But... |
Why is America going through a heroin epidemic? | I know i'm gonna get flak for this, but with the US being in afganistan/iraq a shitton of our troops literally spent their days protecting poppy fields.

What is it that separates my brain or mind from that of a genius? | I'm pretty sure its more nurture than nature. If I gave you a piano, for example, when you were 5 years old and you spent most of your childhood playing piano and learning music theory out of genuine interest, by the time you reach your 20's you'd likely be as good at piano as most of us are with our native languages. ... |

- Why all those Africans who had their hands chopped off at the wrist with machetes are alive, but people who slit their wrists with a razor blade aren't. | The risk of death you're thinking about here is blood loss. In the case of an cutting hands off, the people doing the cutting do something to stop the blood loss. For example, if you burn a wound with something hot enough it can stop bleeding. . I don't know what they actually use to stop the bleeding in these cases, a... |
How can NASA's rockets fail, or explode? | There's not a lot of room between 'works perfectly' and 'explodes' when you're dealing with rockets of that size.

By this I mean that you're dealing with an organization with a lot of people, who are under... |
Why aren't parachutes installed on airplanes, so incase anything goes wrong people can just jump out? | You're cruising at high altitude in an airliner full of passengers.

Sometimes when i get up to quickly from the couch i feel dizzy and vision goes blurry what's going in the body? | Back in high school after sitting for an hour on the floor as my coach spoke to my team I stood up too quick and the next thing I knew my team was surrounding me. After that for a few years any time I stood up quick I ran into this same problem. Even a good stretch resulted in me quickly laying my head on my desk or si... |
