I am having a difficult time choosing which path to follow in school. Does anyone have, or know anyone with experience in either of the titular fields? Also, can one, with an undergraduate BSc in Physics, pursue either of the fields in graduate school? Since my interest lies in physics, and I don't want to enter academia as a vocation, I want to enter a field that uses the applications of physics and is lucrative enough to foster a comfortable living. As for engineering, that's on the backburner for now. These 2 fields intrigue me the most at the moment.
