How much of a crossover is there between Aerospace Engineer and Physics for a major as an undergrad. So is there any crossovers, and when taking the physics track, we have to do the Ph.D track?
For the first part, there is some overlap between a physics undergraduate degree and aerospace engineering, but really only for the first two years or so. After that they diverge pretty spectacularly.
I don't honestly understand the second part of your question about the Ph.D. track.
