I am going to be a freshman in college this year, and I am not sure if I want my major to be physics or engineering. I love physics, and I think it suits me more. The only reason I question going into physics is the debt I could accumulate after a phd program. It would also be helpful to hear what the normal debt is after a phd program and to hear what it is like to work in both fields. I am interested in particle or nuclear physics or mechanical or electrical engineering. Thanks for input!
