The Theoretical Minimum: General Relativity

Professor Susskind derives the weak-field approximation of Einstein's field equations, demonstrating their transformation into wave equations. He then develops the theory of gravitational waves from these solutions.

This lecture by Leonard Susskind rigorously derives the Einstein field equations, demonstrating the equivalence between spacetime curvature, quantified by the Einstein tensor, and the distribution of energy and momentum, represented by the stress-energy tensor. This constitutes a fundamental pillar of general relativity.
