Basically you make the computer try to solve really hard problems. When you find a solution to the problem, you can exchange that solution for a bitcoin, which is used as currency.
I think the craziest thing about bitcoin is not how you get them, but the fact that people have given them worth, despite not being an actual object, nor serving any purpose besides being exchanged in lieu of other currencies.
I don't understand this part of Bitcoin, the rest is golden to me. Are these math problems going towards anything, or is it just an arbitrary way of limiting the amount of bitcoin that can be "created" at any time?
People do like shiny things
I can do a lot of things for a silver or gold coin :)
