Pre-Owned Six Not-So-Easy Pieces : Lectures on Symmetry, Relativity, and Space-Time

The spectacular reception of the book and audio versions of Feynman's "Six Easy Pieces" (published in 1995) resulted in a worldwide clamor for "More Feynman! More Feynman!" The outcome is these six additional lectures, drawn from the celebrated three-volume "Lectures on Physics." Though slightly more challenging than the first six, these lectures are more focused, delving into the most revolutionary discovery in twentieth-century physics: Einstein's Theory of Relativity.
