I am entering my second year in college, and I am thinking about majoring physics with an emphasis in astrophysics. If I were to go to graduate school in astrophysics, which minor would best complement a physics major? Mathematics? Computer Science? Or maybe even statistics? If I were to switch majors, I might graduate late because would have to take four quarters of lower division physics during my second year. So far I've only taken 3/4 quarters of calculus, and I'm taking a intro to abstract math course (logic/proof methods/set theory/induction/etc.) right now in the summer because I'm currently statistics major. Would it be not a good idea to minor in anything at all? If I were to minor in something, which courses would you recommend for graduate school?
