# Relativity watch

1. Can someone suggest me , what mathematics should I master to understand genral relatvity properly?
Thnx
2. Eeeeee.

Look up the Kerr Metric.

That kind of maths.
3. Most of the equations are just algebraic. What you must master is the concept itself.
4. Tensors.

Tensors.
Do you think studying set theory would help me in anyway?

No, I can't think of any way that it's even related to GR.

ok thanks , I will start working on tensors.

What level of maths are you up to already? Because to understand tensors you're going to have to have had quite a lot of experience with vectors, matrices, transformations between coordinate systems and partial differentiation.

Well i finished my A level in maths and have done AS level Further maths f, but I do read quite a bit alot of maths related books and have a vague idea of general relativity.
I have done vectors and matrices but as you can imagine basic stuff. So i better start reading up those stuff.

Tensor calculus. Good luck with that. I did it in my third year of a physics degree and I still didn't master it properly.
12. The theory of relativity is a theory you only tell your relatives so shush
13. Depends on which relativity.
SR is a piece of piss. You need to learn basic algebra.
GR is a completely different beast. In which case, you want to learn Tensor Calculus, which prerequisites for include Einstein notation, Non-Euclidean geometry, prerequisite for which include vector calculus and SR.
14. Calculus of Variations would also help
