What kind of advanced maths would I need to understand some advanced physics?

 

I know calculus inlcuding triple integral calc, differential equations, and statistics.

Advanced physics?

 

Too many to list.

partial differential equations is a big one. so is advanced matrix operations.

A good place to start would be looking at a college catalog, and noting what the prerequisite courses are for the various physics courses.

 

For instance, if you want to study quantum mechanics you need to know multivariable calculus, ordinary and partial differential equations, Fourier analysis, and linear algebra. As to linear algebra, you want a course that emphasizes a rigorous treatment of vector spaces.
