33. Gravitational Waves IV: Energy and Momentum (General Relativity)

Lecture 33 on General Relativity. This lecture covers: (1) separation of the metric into background and perturbation; (2) series expansion of the Einstein tensor to quadratic order; and (3) the stress-energy-momentum tensor for gravitational waves.
