Upon doing background research and looking at faculty in my department, it seems that it is easy to move from studying physics to studying applied mathematics. However, I have seen few, if any cases of the reverse, where someone started studying applied math and moved to study physics.
To this end, I am currently an applied math major applying for graduate schools, and although I will be applying to applied math graduate programs, I would like to move into the direction of physics, particularly applied physics. I am wondering if anyone here can describe how one can successfully transition from applied math to applied physics? In particular, what kind of background in physics should you have to be taken seriously? Would it be sufficient to get this background knowledge through reading textbooks on my own, or is there a bias toward learning from classes?
