I am currently in my third year of a physics and mathematics double major. I've taken almost enough mathematics to fulfill the mathematics degree requirements. I plan on becoming a theoretical physicist and attending graduate school. I've listed the courses I've done, and registered for, and will definitely take. I've also taken almost every higher division physics class at my institution and am doing independent studies in advanced topics (another semester of E&M and quantum; survey course in modern physics applications like solid state, nuclear, etc; either QED or QFT/Fields). I have taken: Calc I- III ODEs Linear Algebra Numerical Analysis Foundations of Math (methods in proofs) Registered: PDEs Topology (Point-set) Will take: Abstract Algebra (group theory) Complex Analysis I have worked out my schedule for math and physics classes to take, but I'm not sure which of three classes would benefit me best for one of the spaces I can take a course. The three classes I would like to do are Differential Geometry, Interrelations in Math, and Mathematical Methods for Physics. It's worth noting a few things: The Interrelations course is somewhat unique, the course description reads "Topics include groups, complex variables, non-Euclidean geometry and differential equations with the theme that any two areas are related. Emphasis on examples, applications, and unsolved problems in contemporary areas such as elliptic curves, geometric surfaces, group-manifolds and modern physics. Appropriate for math majors, and non math majors who are interested in seeing what lies beyond calculus." The math-physics course would be an independent study. I attend a small liberal arts school, and I am one of two physics students double majoring in math.. I would like to do a survey of different topics, tensors, calculus of residues (I'll learn it in complex, but reviewing won't be bad), differential and integral equations, and some topics in Clifford algebras and dual spaces. I'm currently doing a little bit of study in differential geometry, specifically of surfaces and geodesics. So I'll have some exposure to the material, although I admit I'm not extremely comfortable with it. I'm not sure which of the options will benefit me most as a physicist. I'm fairly confident that they will all be beneficial. Any insight or advice is greatly appreciated.
