"Я не червонец, чтобы всем нравиться" (Бунин И.)

Physics is like sex. Sure, it may give some practical results, but that's not why we do it. (Richard Feynman)

A little learning is a dang'rous thing;
Drink deep, or taste not the Pierian spring:
There shallow draughts intoxicate the brain,
And drinking largely sobers us again.
