I'm a junior in university right now, hoping to attend grad school for physics. At my school, all physics students have a senior research project, and the professor that I'm most likely going to do my project with is a string theorist. The project is very theoretical (i.e. no computers; purely pen and paper). I do enjoy the work and I am very close with the professor. However, I'm worried that I'm hurting my chances for grad school by not developing more useful skills with this project. The student currently working with him has had difficulty with grad school acceptances (though he has done no other research as an undergrad, for the record). I've done (gentle) computational research as a sophomore, and I've been accepted for an external REU this summer, probably with computation or possibly experiment, so I have other opportunities, but will I be taking a hit by not doing another project? There are many other ones to choose (with experiment and computation), but I am interested in this one and this professor if it's not going to hurt me. Any thoughts?
