21. Stress-Energy-Momentum Tensor (General Relativity)

Lecture 21 on General Relativity. This lecture covers: (1) how an observer extracts the energy density, momentum density, energy flux, and momentum flux of non-gravitational fields from the stress-energy-momentum tensor; (2) dust; and (3) components of tensors in Fermi normal coordinates.
