General Relativity (MIT 8.962)
Graduate general relativity: differential geometry and tensors, Einstein's field equations, experimental tests, black holes, gravitational waves and cosmology. 23 full lecture videos, prose lecture notes and problem sets give learners the working tools used in Carroll-level study.
Lectures on General Relativity by Frederic Schuller (Gravity and Light 2015)
Frederic Schuller's lectures and tutorials from the 2015 International Winter School on Gravity and Light, building general relativity from topology, manifolds, tangent spaces, connections, curvature and integration on manifolds. Afterwards learners can follow the geometric formulation of spacetime and gravity with mathematical rigour.
