Six Not-So-Easy Pieces: Einstein’s Relativity, Symmetry, and Space-Time

Richard Feynman

“Richard Feynman became a legend among students and physics teachers thanks to his hilarious and brilliant teaching style. At the California Institute of Technology, Feynman gave lectures that transformed how physics was taught between 1961 and 1963. In Six Not-So-Easy Pieces, a collection of excerpts from his renowned Lectures on Physics, Richard Feynman explores one of the most groundbreaking advancements in twentieth-century physics: the theory of relativity. Both scientists and laypeople initially found it disturbing to consider that the passage of time is not a constant, that an object’s mass depends on its velocity, and that the speed of light remains constant regardless of the observer’s motion. However, as Feynman demonstrates, these perplexing concepts are not merely dull physics laws; they are things of beauty and elegance.

No one, not even Albert Einstein, was able to convey these complex, counterintuitive ideas with greater lucidity or enthusiasm than Feynman. Six Not-So-Easy Pieces is an excellent introduction to the principles of physics written by one of the most famous and approachable physicists of all time. It is full of wonderful examples and ingenious visuals.”
