Six Not-So-Easy Pieces: Einstein’s Relativity, Symmetry, and Space-Time
Why I recommend it
Feynman works through symmetry, relativity, and curved space-time. He builds surprising ideas from questions about what we can measure.
What stayed with me
An idea that feels impossible at first can become understandable when we follow the reasoning one step at a time.
Who it’s useful for
Readers with some algebra and physics who want to go deeper.
A tension or limitation
The title is fair. Expect to reread passages and look for additional explanations.
