Why is my corporate e-mail inbox so small (250 MB) when Google gives me 15 GB for free? | There are good legal reasons to keep data retention low.

This results in long wait times for people legitimately calling in. If the c... |
When Bruce Banner in the Avengers says "That's my secret. I'm always angry". How does that make any sense at all? | Loki's Spear exerted subtle influence on everyone in that scene on the Helicarrier.

"Three guesses, and the first two don't count" | I think your last theory is correct. It probably derives slightly from 'three strikes and you're out'.

That might not... |
Trading in your car for another when you still owe money on it? | And just to add, trade-in an upside down car loan with new car loan is horrible idea.

Why do so many sitcoms and shows feature a fat, stupid husband and patient, long suffering wife? | So it's either appealing to women, who get to see a smart, sexy, competent representation of themselves and feel good.

I think it's worked well for t... |
How do games that run in 30 or 60 FPS record time down to the milisecond? | ~~Computers have multiple clocks. There's a clock used by video hardware to decide when to output the next pixel, and ultimately the next frame. When using some form of [vertical sync], this determines when frames show up.

Why classical musicians use sheet music and others do not | I may not be the best person to answer this but many classical musicians will have the song memorized if they are playing a single piece .

Using metal objects (like a necklace) while holding vitamins and using the way it swings to determine how many of the said vitamin to take. | That's one of the dumbest thing I've ever heard. There are multiple things wrong with it. Dowsing for vitamins won't do anything of value to pick the vitamins.

Why do big oil companies spend millions on stopping electric cars instead of investing that money in advancing the technology? It would seem that the ground breakers stand to make a lot of money. | What exactly is the evidence that oil companies are actively sabotaging electric car development?

Why do drug companies release generics of their own product? | They do this regularly simply because of the result.

Why are we able to "painlessly" put down our pets with drugs, but often botch lethal injections? | I haver never tried it but you hear heroin addicts say that the first time you try it it's amazing.

As an example of this, ... |

What exactly is gentrification and why is it considered a bad thing? | The issue is that it pushes out working class families out of their neighborhoods, as they get priced out.

How does the body wake up when being startled/jolted vs waking up on its own? | Side question - For those people with small kids who constantly get woken up in this way by screaming, how does the body adapt?

Why do mentally ill people self-harm? | Self harm is such a complicated thing. The reasons it happens are so different and numerous that it would be hard to adequately explain I think. I can't say for sure what the specific drive is, or necessarily a clear, defined reason it happened in my case. But originally, for me, I was raised in a very controlling hous... |
Why is the American drinking age higher than other contries'? | Car culture in the US plus irresponsible drinking habits. For many American youth, there's no way to get to a bar or even to your friend's party without a car- it's too far to walk, there's no public transit anywhere near where you live, and biking on the fast roads into town is too dangerous. That lead to a large numb... |
What proof do we have of Mole Theory? | We're absolutely sure that 1 mol contains that number of particles because the very definition of 1 mole is however much stuff that contains 6.02 * 10E23 particles. So it's not a theory, it's a definition. |

Why are my mustache hairs straight, but my beard hairs look like pubes? | The shape hair makes when it comes out is, funny enough, actually determined by the shape of the individual hairs themselves. Because of how the stuff hair is made of fits together, if a hair comes out perfectly circular, it's very straight and all of their hair will lie together flat and smooth. If it is just a little... |
my Asian neighbor puts steaming beans on their cars. What is going on here? | It's not beans, it's fern shoots. The quantity also doesn't mean they're trying to sell them. They cook them, then they shrink when they dry. Each one of those thick stalks dries up into a tiny twig. Once they're dry they can be stored like that for a very long time. The season to pick them is short so likely they're c... |
Why isn't there enough emphasis into exploring our oceans? 90-95% is still undiscovered. | You ever wonder why James Cameron gets so much ocean exploration done? He's rich and can do it as a hobby.

How come obvious political corruption happens in America, but we never do anything about it. | There are lots of orgs and groups dedicated to that. Just because 1 person isn't doing anything doesn't mean noone is doing nothing", 'One of the biggest "Obvious political corruption" things is lobbying's existence. Unfortunately, lobbying serves a good purpose, as well -- without lobbyists, experts from industries wo... |
How come when you wake up your bed feels entirely more comfortable than when you initially try to go to sleep (or even throughout the night while you're sleeping)? | There's like four different answers here all saying different things. Which one is the real one? Can I get sources for answers?", 'I don't think anyone truly knows.

How come Chinese don't get sick more frequently, or even start an epidemic, seeing as how they treat and handle meat? | This is because in the west we are WAY too overprotective and focused on cleanliness.

If we invent math to describe the Universe, then it matches so well because Newton were ... |
How tabloids in supermarkets like National Enquirer and The Globe are still alive, even they have low credibility? | I know two people who worked for The National Enquirer for over 15 years.

Why do some astronomers think there is a ninth planet in our solar system? | Because mathematically, we can see the effects of the gravity from another body, but we hadn't found it.

if I wanted to get up and move to a different country how would I go about that? | There's an entire subreddit dedicated to this: _URL_0_ With that being said, as an American the easiest would be if your occupation and education appear on the Nafta job list : _URL_1_ If it does and you find a job in your field in Canada or Mexico, it's fairly easy to get a 3 year work visa. You can continue to get 3 ... |
what was the reason to split programs into interpreters and compilers? | An interpreted language does not need to be compiled, this means that it is faster to change something and try again, so potentially better for learning to program.

How is it you can get a sunburn at the beach while sitting in the shade? | Unless you were sitting in a pool of total darkness, some light was still hitting you.

Renting vs Buying a home | So, lets say you get to 65, still working, still renting. You retire. How are you going to pay the rent ?

You might decide to downsize after all the kids have gone, giving you a place ... |
What is the point of this USB adapter? | I suppose you could use it as a standoff if you needed more distance from the port. Sort of like a [motherboard standoff screw]. Otherwise I'm not certain what the market would be. |
Why do people use cheque cashing businesses instead of a bank? | Some people do not have bank accounts or cannot easily get to a bank to deposit their check. A lot of check cashing businesses also offer high-interest loans for people who can't get them elsewhere. Check cashing businesses tend to set up shop in economically poor areas.

How to explain multiple passwords to elderly grandparent | Perhaps an analogy could help. Her passwords are like keys that she uses to access different content online.

what happends if a blind person takes LSD? | I will tell you this now if you take LSD just for the visual effects, you might not want to take it cause you will be in for a ride you did not expect. I taken LSD once and the visuals were minimal. It is hard to explain an LSD trip in words. Just know that it is very very very cerebral. It allows access to parts of th... |
Does a psychiatrist ever get treated by another psychiatrist? Do the treatments work since they already know the mental techniques used? Or does a psychiatrist treat themselves? | My personal bias here: it's unfair to treat clients when the clinician has never experienced what the client is experiencing. As for undergoing therapy while providing therapeutic services: it's mandatory in some training programs for good reason IMO. People come to you with their troubles, so personal problems aside, ... |
Why do we get scabs? | Do you mean scabs after we get cut? These things called platelets in our blood are designed to stop the flow of blood and help seal up the wound before skin can grow.

I am going 75 MPH down the interstate. What will happen if I jam the shifter into reverse? | Automatics just wont do it; drive by wire transmissions wont do it. If you find proper analog manual car. 75mph would be just plain too fast. Reverse is a large gear like 1st gear not meant for fast speeds. So you just can't do it at that speed. However if you were only going 5-10mph. I bet you could do it. |
What exactly is Obamacare and what did it change? | I never thought of Police, fire, and emergency services as something i am 'forced' to pay for but they are. What is the difference with someone dragging me from a fire and someone treating the burns? Wow. I was so adamantly against a mandate but I am mandated to pay for so many things already. And I wouldn't have it an... |
Why would we want/need to "switch" planets? | The most likely reasons we would is if we survive long enough for the Sun to start burning up our planet and making it unlivable. There's also over-population, but that wouldn't make us leave our planet all together; just send more people to other planets to colonize.Obvious, sci-fi style reasons : incoming asteroid, b... |
why does the body physically hurt when emotions are strong? | When I get really upset I experience this intense concentrated aching in my throat. It makes it extremely difficult to talk. It feels like my body is trying to stop me from speaking. I have no idea what's really going on there. |

Is there a science behind craving human contact at night more than any other time of the day? | I remember from psychology undergrad that oxytocin is released more when you are tired or under mild sleep deprivation.

How are DUI checkpoints legal? | In Australia this is perfectly legal. It has been legislated and passed as law. The police can stop you anywhere, any time and require a specimen of breath and a licence check. No probable cause needed.

Why does time slow down when you're about to be in a car accident? | Slow-Motion Perception! Our earliest record of slow motion perception is from a train wreck in the 19th century, leading some to speculate that this phenomenon did not exist in human brains before industry allowed people to travel at great speeds. Firstly, some obvious stuff 1) time doesn't actually slow down, and 2) t... |
Why is it that when people sleep talk, they say random gibberish that is structurally correct, but syntactically wrong? | Two things are at play: 1) In your brain, meaning is handled by Wernike's area and grammar by Broca's area [0]. 2) When you are awake, your brain activity is integrated , but when you sleep they become functionally disconnected [1]. So, while your GF is asleep, her grammar center gets a life of its own and spews nonsen... |
Why having two Sith or just the Dark Side of the Force, in the whole entire universe would be a bad thing for anyone who isn't a jedi? | The sith believe that their connection to the force can be made stronger through passionate emotion. Every aspect of their emotions are exaggerated to this aim, and the most easily expressed of these emotions is anger. Anger so often leads to violence that a very angry force-wielder could be a galaxy-scale catastrophe ... |
why do Olympic gymnasts like Shawn Johnson not compete in college? | -Gymnasts, women in particular, peak early. It's not uncommon to go to the Olympics at 16 and be considered a veteran reaching the end of their prime in your mid-20s. -Gymnastics in the US is FAR more popular in the runup to and wake of a Summer Olympics than in the other three years between them. -Both of these factor... |
In the Christian context, what is the "Holy Spirit?" | I'd put it in really simple terms like this: God is.Jesus physically is. The Holy Spirit actionably is. God is pure existence. Jesus is the physical manifestation of pure existence . Holy Spirit is the action taken by this pure existence. God is a musician, the Holy Spirit is the sound coming from his instruments.God l... |
Why do people get so excited about tax write-offs? | All other commenters appear to not have a full grasp on what it means to be in a different tax bracket in the U.S. I'll use /u/GenXCub's comment as an example with the 2014 tax brackets.I'll assume the $92,000 is the result *after* all standard/itemized deductions and write-offs. With *marginal* tax brackets, your tax ... |
What exactly is that target-shaped indent both of my parents have on their upper arms? Were shots just a whole lot stronger back then? | Should be for tuberculosis, if it's the same as my parents'. But they got theirs in a different country, way back when.It's MOST likely small pox vaccine. It's not just on shot though. It's actually a series of shots given at one time. 5-7 times is what I believe it is. Basically the nurse/doc pokes you 5-7 times reall... |
why is 9/11 considered such a huge deal while there have been events with much more death since? | Because it was a successful, foreign attack, on US soil, against civilians - in the middle of the world's most important financial capital. There hasn't been anything of that magnitude, especially during an era of *peace*. Only thing I can think of that comes close is the Oklahoma City Bombings. Yes, it was tragic - bu... |
With billions of stars in our galaxy, why is the night sky so dark? | > why is the night sky so dark? Surprisingly enough, nobody bothered to explain what light pollution is. Light pollution, well, it's exactly what it sounds like. If you live in a city or near a city, the amount of artificial light produced is so large that it significantly overpowers the relatively faint light coming f... |
How do scientists calculate the age of the earth/how do they tell the difference between a 4.5billion year old rock and a 10 year old rock? | The age of the earth was determined by the decay of Uranium, but it's important to know how much your total sample is. For example, we know that unstable uranium decays into lead. So when we dig up rock and we see: rock rock rock uranium lead lead rock rock rock This tells us that the lead used to be uranium, so we kno... |
Why do we still use X-Rays when ultrasound machines exist? | General: What imaging modality is picked largely has to do with the physics of how that modality works. If you want to see a fracture in bone you are much better off to take X-rays then to ultrasound. If you want to look for pathology in the lungs you are much better off taking X-rays then getting an ultrasound. Both o... |
How do enzymes function? | An enzyme doesn't make a reaction work faster; it reduces the amount of energy required to make a reaction happen. The substrates, the things that react with each other, fit into certain places on the enzyme. The enzyme then facilitates a reaction, and new elements formed from the old substrates drift away. |
