Hi, I'm new. I just graduated with a BS in mathematics (pure bent) from a state university in the US. I ended up taking 7 graduate courses - two semesters of measure theory, a semester of functional analysis, two semesters of complex analysis, a semester of general topology and a semester of algebraic topology - receiving 6 As and one A-. In addition, I took a variety of undergraduate courses (hyperbolic geometry, probability, two semesters of applied PDEs, numerical analysis, number theory, undergraduate algebra, etc), all with high marks (gpa in the 3.8ish range). However, what I have had precious little of is physics. Outside of the introductory course I was required to take, I've taken none. I've started studying Griffiths QM and EM books this summer. Getting to the end of my undergraduate degree and looking towards graduate school, I realize that I'd much rather be in physics than mathematics, for a variety of reasons. I'm going to obviously talk to professors in the physics department I just graduated from, but I was wondering if anyone could give me some advice on this: I'd like to go into graduate school for physics. I do not want to do another undergraduate degree. Is it possible to make the transition from mathematics to theoretical physics? Will my pure mathematics training be entirely wasted? Edit: Deep apologies if this would have fit better in the Career Guidance section.
