I'm now going into my Junior year of college looking to major in Physics. The last math course I've completed was Calculus 3. I read through the course outline and it listed that a the last lower division math I'll need to complete before I start their Physics program. It looks like Diff. Eq is apart of the Mathematical Physics course listed. I'm interested to know what other math classes would cover the rest: Mathematical Physics: prereq: Mathematics 250A (Calculus III). Survey of mathematical techniques required for upper division physics courses including differential vector operators, complex variables, partial and ordinary differential equations, special functions, Fourier transforms and series, matrices and operators, probability and statistics. Classical Mechanics: Classical mechanics and associated mathematical and numerical techniques: Newtonian dynamics; Lagrangian and Hamiltonian dynamics. Modern Physics: A survey of modern physical theories, their experimental foundations and applications: special relativity; quantum physics of atoms, molecules, and nuclei; introduction to solid state physics. These of course aren't all of the classes, but I hopefully someone who can shed some light on this subject. I'm a little confused though because I thought I needed a Linear Algebra and formal ODE course at least. Anyways, any help would be greatly appreciated.
