<p>Physics major from Ga. Tech here, but my experience was so long ago as to be irrelevant to this discussion. I did not contemplate going to grad school in physics, but one of my professors did invite me to apply as a PhD candidate for research in his area. It was way too narrow for me. I first did a stint teaching HS physics and math (2 years), but then returned to grad school (back at Ga Tech) in Information Science (sort of a theoretical computer science). I’ve had various research and academic jobs since, including a 2-year appointment in the Comp Sci Dept at CMU (AI Lab). My big interest, physics-wise, was cosmology, but that’s not exactly a wise career choice.</p>
