Summary

We finish the chapter on The Great Conservation Principles, and move on to Symmetry in Physical Law. We understand what it means for an object to have symmetry, but what about a mathematical expression of a physical law?
This chapter is full of interesting concepts, delivered in Feynman's unique style as always. We discuss relativity, lightspeed, gravitational lensing, angular momentum, and how to tell an alien the difference between "right" and "left".
