I'm a recent physics major and a recent math major. I wanted to do both because I've always wanted a graduate study in Cosmology and for some reason I though it was better to do both. Right now, I'm seriously inclined to study theoretical physics instead. However, I read in this forum (or another forum, maybe) that cosmology is an under rated study. I've been "forced" by society and economic pressures (pressures done by me on me too) to explore financial aplications of these disciplines. I've been exploring a bit. Right now I'm in a great actuarial sciences symposium and it is generally very BORING and sometimes it seems unethic in many aspects. There are few interesting topics and I've been thinking that I could enter this world and find something interesting, but I'm not sure of that. So my questions are: 1. In general, what should a mathematician which is also a physicist do? 2. Has anyone experienced this? What did you do? 3. What is your advice, in general? I would really apreciate your answer.
