I want to ask a professor or two about possibly doing research for them. I'm only a sophomore and my major is Astronomy and Astrophysics. His field of research is loop quantum gravity, string theory, cosmic matter-anti matter asymmetry, singularity resolution, electroweak symmetry breaking and more cool stuff like that. Of course I don't have a formal education in that kind of thing. The most I know about it is stuff I read in popular books like the elegant universe, stuff I see on the history channel and so forth. I can go pick up books at the physics library and stare at them, but the mathematics is far too complex for me. I do have a decent understanding of a lot of physics concepts. This includes calculus, vectors, mechanics, E&M, Astrophysical subjects, statistical mechanics and so forth. But not the level of theoretical physics that he studies. I suspect that if he were to employ me, it'd be with really simple stuff like fixing code in computers or whatever. But I'll still get the experience and resume stuff. How do I go about asking the professor? I do get a little nervous about these things. No idea why. Any pointers?
