Although I asked a similar question two days ago, i'm still seeking an (biased would be nice) answer. So far Physics major seems like the right choice, Physics is still my passion. But, there are always "buts", I would like a major more applicable in the real world. My major choices are: Physics, CS, EE, Econ. Don't really like the idea of being a Engineer( maybe my idea of being one is misconstrued) seems way to practical and day to day life would have no theory or abstractness. I have a tenacious interest in Econ, well rounded major, interdisciplinary, involves math, etc. Comp Sci appears to be the most applyable, you can do almost anything with a degree in CS, apply it to math, any science, business, etc. But I would really like the possibility of a PhD, but the way I see it a PhD in CS seems obscure , since i's not that pure(although it is developing at an outstanding rate). What I would really want to do is R&D but with the possibility of starting my own business/lab relating to my major, specifically research in Quantum computing, AI, Energy, photonics, and Nanotech.
