Hey guys, I'm new here. I read Zz's 'So you wanna be a physicist', great post and I learned a lot about it. However, I have some questions pertaining specifically to theoretical physicists. Are there less theoretical physicist jobs than experimental physicist jobs? What constitutes a theoretical physicist's job anyway? I'm under the impression that they work a lot with mathematics and [duh] theory, but do they do any experimental work at all? This seems as though they're confined greatly to faculty positions at universities. I have a great passion for mathematics and physics, especially theory, but I don't want to major in mathematics or computer science because I really love physics and that incorporates both (or all three). What exactly do theoretical physicists work on? I mean, is it more difficult than experimental physicist jobs? Are there actually jobs for theoretical physicists to actually work as theoretical physicists? Also, I have a few questions about research. Do undergraduates often do research simultaneously during semesters? When do they usually begin? I'm very eager to start but I don't want to get off on the wrong foot asking researchers for things that aren't even feasible or sensible. Any advice at all is appreciated, thanks.
