The character of physical law

A series of classic lectures, delivered in 1960 and recorded for the BBC. This is Feynmans unique take on the problems and puzzles that lie at the heart of physical theory - with Newtons Law of Gravitation; on whether time can ever go backwards; on maths as the supreme language of nature. This collection demonstrates Feynmans knack of finding the right everyday illustration to bring out the essence of a complicated principle - for example, the brilliant analogy between the law of conservation energy and the problem of drying yourself with wet towels.
