22. More Stress, Energy and Momentum (General Relativity)

Lecture 22 on General Relativity. This lecture covers: (1) the variational principle definition of the SEM tensor; (2) interpretation of symmetry of the SEM tensor; (3) the correspondence between momentum flux and stress; and (4) energy and momentum conservation.
