    At 8:50  mind=blown.... How come I didn't learn this in school? I mean we used pythagorean theorem, but we had no idea what it really was.

    And it seems in many schools, teachers suffice themselves with teaching you how to solve a problem without telling you why that works. And I personally believe retention is better attaned when one nows why something works just as much as when they learn how to do the something.
