I am an aspiring physics major attending a small liberal arts college this fall, and lately I've been considering whether to go for a second major. My long-term goal in my academic career is a PhD in physics, and to that effect I plan to take courses in physics and mathematics beyond the requirements of the major. (Besides the fact that most of them excite me, it is also good for graduate school admissions, right?) Unfortunately or otherwise, I am also quite enthralled by the prospect of going for a second major in philosophy or a social science. My reservations are: I'll have to overload consistently for a few semesters. I'm afraid that my GPA will be affected. I'll have to do two theses in my senior year simultaneously. I might not be able to take as many physics courses as I would have been able to otherwise. I'm afraid that my GPA will be affected. I definitely don't mind having to work harder for it to happen, but I am quite worried about the possible consequences for my admission to graduate programs. Do admissions place heavier weight on one's overall GPA or major GPA? What looks better - a higher GPA or a heavier and more varied course load? This has ramifications too on whether I'll be inclined to take more classes in the other liberal arts even if I don't go for the second major. The interest is there, but so is the fear. I was also previously tempted by the 3-2 engineering program with Columbia. Engineering in general doesn't excite me as physics does, though I'm quite interested in aerospace engineering, specifically aerodynamics and orbital mechanics, and have often toyed with the idea of working in the aerospace industry. Going for the program however would mean having to work for a year or two after graduation due to certain financial circumstances, delaying graduate study. It would also mean missing the thesis year in my college, which honestly sounds quite exciting. My college has quite a reputation for the rigor of the senior thesis too, and I think graduate schools will look upon the experience favourably? Well, I've been babbling on for quite a bit now, and I'm not even sure if I've been coherent. I'm sorry if I seem to be fanatically focused on not hurting my prospects for graduate study. In summary, should I do a second major? If you have anything to say regarding my decision with the 3-2 program, please do comment too. I will really appreciate any help with this. It's been bothering me quite badly for a while now. I know I can probably wait to decide, but I [STRIKE]want[/STRIKE] need to have at least some idea of what I'm intending to do.
