Hi everyone, I am currently a double major in electrical engineering and physics, and trying to decide which area of physics I want to go in to for graduate school. I'll be a junior next year in EE and I have thus far only taken the physics classes needed by EE's. Will someone tell me, or point me in the right direction, where I could find a list of all the general fields of physics? At my school now, optics is the major area of research in the physics dept. I would also like to know if anyone has suggestions that would help to get into one of the top schools in physics (when ever I find out which field I want to go into). I know GPA and GRE subject test are very important. But if I, say, have a 3.75 GPA and a fairly good GRE score, then what will guarantee me admission into one of the top schools? I am currently only at a state university (no ivy league). Would I essentially have to be involved in ground breaking research to have a chance at the (very) top school? Thanks a lot in advance, and sorry if this is not in the right forum.
