Motion Mountain - "The project aims to produce a simple, vivid and up-to-date introduction to modern physics, with emphasis on the fundamental ideas of motion. 'Simple' means that concepts are stressed more than formalism; 'vivid' means that the reader is continuously challenged; 'up-to-date' means that modern research and ideas about unification are included."
