Hello. I am enrolled for the UCSB summer research mentorship program and was interested in researching in the field of Physics... I was asked to pick a sub-discipline in physics which i might be interested in... 1) The question I had was, what are sub-disciplines in physics? are Thermodynamics, particle physics subdisciplines? If so, could someone list some more please? 2) In which discipline would the research be most interesting or does it depend on personal preference? I am not sure what I would want to do ...I am interested in Electricity and such but not sure if there might be other things that I might interest me which I cant think of at this time. Thanks a lot.
