Here is my problem... On the one hand: I know I love mathematics, and enjoy being able to describe physical phenomena with it. Predicting the future with such an incredible degree of accuracy is FUN to me. I know I love fishing out the secrets of the universe, and mulling through the different possible ways to describe literally everything in it. I love picking apart equations, trying to fit the pieces together in a way that hums along with the reality. I love looking into the deepest level of detail possible to find flaws and insights. On the other hand: I really want to develop an alternative energy source that has a high efficiency rate and can be found throughout the galaxy. This means a combination of nuclear fission reactors and propulsion systems, nuclear fusion reactors, and possibly particle annihilation reactors and propulsion systems. I would like to be ABLE work on any/all of these technologies if I could. So, what do I do? What should I major in? I know I'm in physics for the long run, but nuclear? theoretical? high energy? ... I don't really know what to choose.
