What blew your mind?
pavelludiq: My mind is like a war zone, i blow it up very often. Most recently it was my realization that is math easier(and much more fun) if you approach it as a mystery to be solved, rather than a sport, like they teach you in school. Yes, they do teach it like a sport: learn the skills, and then apply them to 4 problems in 40 minutes, each problem is harder than the previous, and if you succeed, you get rewarded with a better grade. This is the most boring sport ever! This is mind-blowing to a 19 year-old who spend 12 years in pointless training of a sport that isn't fun, to get rewarded with something he doesn't care about. Man, i feel cheated.Other examples of recent mind explosions include:when i "got" recursion last summer.when i  "got"(sort of)pointers in C.when i "got" what trigonometry really is, now all i have to do is "get" it itself.when i found hacker news :D
