I was wondering what would be the best choice of major to go into to prepare to do research on new types of non-combustion propulsion (that function in a vacuum, doesn't have to work in the atmosphere as well)? Most of what I read today seems to lead toward next generation propulsion being largely about electromagnetics, plasma, and lasers. I really liked studying about electricity and magnitism in physics 2, and while I've never studied it before, plasma has always fascinated me (And not the type I 'donate' to pay for school :P). Lasers are interesting, but while I would like to know a little bit about them, I really wouldn't want to concentrate on them. Does anybody have any ithoughts? Thanks for reading.
