Hi, I'm an about to be CS graduate but my interest in physics greatly outweighs that of programming or developing software. Especially theoretical physics or anything related to physics for that matter so what I'd like to do is to go into a physics job however not having a physics degree I don't know how I'll go about doing it or which job I can even go into. I think a wise choice would be to go into a career which is a mix of the computing/physics related work but then I'd like to work my way up to get into physics completely. What kind of career would be good for me in this case? And how can I go about doing the above? Also, does having a degree in one subject mean you're limited to careers only in that field in life or is it possible to switch to something else as you find your true interest.
