I have searched the forums for this thread and have read several threads but I still have a few unanswered questions. Which major will involve more of the interactions between subatomic particles? Right now, chemistry is very interesting to me because it deals a lot with the interactions of the atoms and how and why nature behaves the way it does. However, looking back on the advancements made in chemistry, I notice quite a few of the advancements were done by physicists. Also, reading about physics really has me interested because from what I can tell, physics is more involved with day to day things which excites me. Quantum mechanics especially. My original plan was to get a phD in physics and pursue a career in academia. Over 50% of physicists don't have a job related to physics, apparently. If you have received an education from an Ivy league, will your chances increase? Also, what are the career prospects in nanotechnology with a physics phD?
