The character of physical law, first published in 1965, contains the text of seven brilliant lectures, originally delivered to standing-room-only audiences at Cornell University, that demonstrate Feynman's unique ability to bring his subject to life to the non-physicist. Beginning with a discussion of the Law of Gravitation and of the essential interaction of mathematics and physics, Feynman goes on to explore the principles of conservation and symmetry and the irreversibility of time.
