hello guys, this is my first post here.. i am a engineering physics undergraduate. however i hv more interest in theoretical physics and i want to hv further study in theoretical physics. The subjects taught in my programme is like applied physics which do not hv so much theory. I think having a good foundation of theory is extremly important. So, i would like a ask for a list of topics that theoretical physicist has to master. (both Mathematics and Physics topics) also, any physics undergraduate can share their programme list? thank you.
