Six Not-So-Easy Pieces: Einstein's Relativity, Symmetry, and Space-Time by Richard P. Feynman

2.0

Just like the title says, not as accessible as the first book. I enjoyed the first two chapters about symmetry even if I didn't get all of the specifics. Then relativity required too much work for me right now. Maybe I'll come back to it when I have more motivation.
