How can global warming cause more extreme winters like those seen in North America this year? Isn't that kind of counter intiutive?
[ "Basically, we're not necessarily going to see just warmer weather- we're going to be seeing more *extreme* weather in general. Global warming is what it sounds like- but it's taken by the year, on an average, and the entire global climate is taken into perspective. \n\nAnd that average temperature is increasing an...
Why do our shoelaces come loose?
[ "A shoelace bow is a modified square knot. If you do it wrong, it's a granny knot, and it'll come loose.\n\nMake sure the crossing of the loops/ears is opposite the first crossing.

What's so great about Linux?

The software is written by people who want useful software more than th...
Bilge Pumps
[ "It's probably ballast water, not bilge water. When the ship is empty they pump water into ballast tanks to lower the ship into the water deeper and keep the ship more stable. As they load the ship they pump that water out." ]
how does a computer delete a file. Where does all that information go?
[ "Your computer keeps a list of where all your files are located on the hard drive. When you make a new file, it checks this list to make sure you don't use space that other files are using.\n\nSo when you *delete* a file, your computer just deletes that file's entry from the list. Then, if you make a new file and t...
How do hackers earn money?
[ "It depends really on their nationality.\n\nMost hackers in america at least will moonlight as normal people for most of the day. Think of the opening of the Matrix. Neo works an average desk job as a computer programmer, yet he still hacks. This is more common then you think. A lot of hackers (see when Anti-sec wa...
Why, in Australia, are we subsidising the mining industry?
[ "Due to corporate influence in our political system and media.\n\nSince about 2011 or so, just after the Rudd years when the Mining Tax was proposed, high-level corporate figures - mining and otherwise - [colluded to manipulate public opinion](_URL_0_) around the mining industry and corporate regulation within Aust...
In Law, what criteria do they use to separate real threats and banter?
[ "It depends on your legal system, but most first world legal systems have a prosecutable charge for the *threat* called \"uttering death threats\", which is entirely different from the *intent* to actually go through with it. That's called \"~~planning~~ edit *conspiracy* to commit murder\" or \"attempted murder\" ...
I was told once that you wouldn't feel pain if your intestines were cut but would if they were stretched. Is this true? And if so, how is that possible?
[ "There are different receptors in different parts of your body passing on different information to your brain. Your internal organs have a lot of stretch receptors that help them know to move food along or tell you you’re full (in the stomach). You don’t have pain receptors in many of your internal organs. An examp...
Why America doesn't have Home Economics?
[ "So the big thing is that America USED to have it. But budget cuts have meant that most public schools have been forced to remove those sorts of programs because they have to focus on just the basics. Many schools can't even afford art classes or music. \n\nThat being said, most Americans I know would love it if Ho...
How different/similar is Android to other traditional GNU/Linux Distros (targeting desktop/other platforms) out there ?
[ "You're right that Android runs on the linux kernel. That's about the only similarity it has to traditional Linux distros. Everything else in Android differs completely because there are almost no GNU components in the rest of the system (the exception being the kernel itself)." ]
Why does our hearing muffle when we stretch?
[ "The ear has a Eustachian tube which is a pressure regulator in order to prevent your ears from popping out. When pressure changes in your ears the Eustachian tube which is normally closed opens. It also opens when you chew, yawn or stretch.\n\nSo the reason we don’t hear external sounds as well when we stretch/yaw...
