Well, actually I am a designer (UI/UX), and I didn't learned any math in schools and university. But, one day, my wife brought me a beautiful version of Euclid's Element. Since then I started learning math, the most beautiful subject that human beings ever possess.

Well, I am not a busy man. There are only three things in my life: learning math, skiing and art. So if you have any suggestion for my silly questions but don't want to comment publicly (in some case maybe), please feel free to contact me via email ([email protected]) or via iMessage ([email protected]).

Live long and prosper!
