Six Not-So-Easy Pieces

Professor Feynman's teaching style has inspired generations of physicists. His lectures have been transcribed and published in Six Not-So-Easy Pieces. In these lectures, Feynman addresses one of the most revolutionary discoveries in twentieth century physics--Einstein's theory of relativity. The notion that the flow of time is not constant, that the mass of an object depends on its velocity, and that the speed of light is a constant no matter what the motion of the observer initially seemed shocking to scientists and laymen alike. But as Feynman shows, these tricky ideas aren't merely dry principles of physics; they're things of beauty and elegance.
