Six Not-So-Easy Pieces: Einstein’s Relativity, Symmetry, and Space-Time
#Non-fiction
Thinking & Decisions
Why I recommend it
Feynman develops ideas from the relationship between physical laws and symmetry toward special relativity and curved space-time.
What stayed with me
Counterintuitive ideas become graspable when each claim is tied to what can be measured and which relationships remain unchanged across perspectives.
Who it’s useful for
Readers with some comfort in algebra and basic physics who want to move beyond popular summaries of relativity.
A tension or limitation
The title is candid: these pieces are not introductory in the everyday sense. The compressed format can require outside explanations and repeated study.
