American physicist Richard Feynman - one of creators of quantum electrodynamics, Nobel laureate, but foremost is the outstanding many-sided personality not written into the usual scopes of character of "science man".He was known for the predilection for jokes and drawing, wrote amazing portraits, played the exotic musical instruments. Magnificent speaker, he converted every lecture into keen intellectual game. Not only students and colleagues but also people simply led away by physics broke on his performances.The credo as a science popularizer he described one brilliant phrase: "If you are a scientific, quantum physicist, and can not in few words explain to the five-year child, what engage in, - you are a quack".
