Hi all, I've made a few topics about my future master. Now the time has come for me to really decide and I still don't know. It's either nuclear physics of cellular biophysics. I'm very interested in both of them, but it's a huge decision I'm making and as always with big decisions I'm uncertain what to do. My first idea was to pick the most interesting one but obviously that failed, because I think they're both very interesting. I really loved the introductory course on nuclear physics (using Kenneth Krane's book) and also the few biology oriented courses I've had (human physiology, cell biology) I want to get into research (who in physics doesn't). Since biophysics is something interdisciplinary and I'm so far the only one with a physics background who has informed about the master, the chance that I'll be able to get a Ph.D. position is greater. But is this a valuable criterion? Also the possibilities seem very large from imaging techniques to statistical mechanics. What are other good criteria for choosing a master? What made you choose for a certain path in physics?
