re: #151 Belafon

General Relativity is a classical theory.

If you’ve not had an intro physics class then it is good to start there, with the basic (calculus level) physics.

Then the next step is the upper division classical dynamics course. It will make you better at understanding the meaning of dynamics and playing with vectors and maybe tensors.

Then comes GR. GR as taught (not necessarily how Einstein first thought of it) mates differential geometry with classical dynamics.

I never liked tensors. The math is the easy part, the confusing part is understanding covariant versus contravariant variables in a physical system. I always found modern physics (quantum mechanics) more to my liking.

See if you can follow along with Susskind’s lectures:
