I am currently working towards a double major in Mathematics and Physics, so that I will have a very good background in both. My reasons are twofold: 1) I want to be well-prepared to study in a Mathematical Physics Ph.D. program like the one at Virginia Tech 2) I have a deep and abiding passion for physics, and I'm developing one for mathematics. The reason I listed the desire to be prepared for a Mathematical Physics Ph.D. program first is that, even though my current mathematical knowledge is limited compared to that of a working theoretical physicist, I already have some (currently rather) qualitative theories concerning the intersection of String/M-Theory, QFT, and GR, and I want to see if I can develop a consistent mathematical model from them. Also of keen interest to me are the theories of Shape Dynamics and quantum 'timelessness' (which seems to me to be more like a true quantization/discretation of time), posited by the British physicist Julian Barbour. I really hope all that didn't sound pretentious, especially since I'm going to be a good bit older than my colleagues starting out, should I follow this path. Certain people in my life won't quit trying to convince me to go to school to learn a trade, and I could likely do well at something like electrical engineering, but I honestly don't think I'm going to be happy if I never know whether these theories I have brewing inside me are viable or not. Thank you for your advice.
