I've just finished up my undergraduate degree and I have been looking at graduate schools for an MSc. Unfortunately, due to my B average, I'm down to basically one choice, which is the institution that I'm presently attending. I've gotten experience in two fields in my undergraduate years: -I spent two summers working in particle physics for EXO -I did an undergraduate thesis in medical physics, specifically bone densitometry As for choosing which field I prefer, I am very interested in both and can't really say that I prefer one over the other. If I were to choose medical physics, I would be in piles of debt down the road because these professors don't have very much grant money. However, down the line I believe there would be many career opportunities. If I were to choose particle physics, I would be much better off financially. However, I've heard that as far as careers go, particle physics is a much narrower field. I've heard stories of post-docs working in particle physics making the same wages as summer students. So I'm stuck with having two different fields that I'm equally interested in, each with pros and cons. One person suggested that I pursue an MSc. in particle physics, and then when it comes time for a PhD., I can pursue a different field. Is this even heard of? Thanks in advance for any suggestions/advice.
