I wonder if minoring mathematics helps career/physics. In my department, some math courses are offered to physics major to make sure that they can accquire enough math tools(since some are compulsory). So, why do some people take math courses in math department or even minor math? I have to declare minor in a few months later. I don't know whether I should spend more time in math or physics such as experiemtal skills. Would you please offer some suggestions? p.s. I am a year 1 student and I want to get PhD after graduate if I can. But I have not yet decided going "theoretical stream" or "experimental stream"
