I did not study chemistry in high school and i finished my year-1 study of physics and math in college. I want to do research in Physics after i finish undergrad. 1.My first choice will be Quantum Physics. However i have no chemistry knowlegde so i might not be able to do condensed matter research. Therefore what particular field of quantum physics with little requirement of chemistry can i do research on(except quantum information)? 2. My second choice will be geophysics. This is quite a dangerous choice as Geophysics requires much knowledge of the chemical properties of rock/earth. Can i still be able to do reserach on geophysics? I know that i will be pretty safe in relativity, string theory or astrophysics(maybe?) as these fields do not require much knowlegde of chemistry. However, i know that i am not smart enough to do string theory while i have little interest in astrophysics so i am really worried after my future. Thanks for the reply.
