I don't think I will be accepted into graduate school because of my very low GPA. Is it still possible to make physics a big part of your career for the rest of your life? I want my career to be physics related. Could I perform my own experiments like designed a cyclotron outside a university? I will have no problem obtaining physics graduate books to study on my own , since I live near a college library that holds all the physics grad books that I am interested in . My own problem would be conducting physics experiments off campus, since equipment needed to conduct the physics experiments you want might be expensive. What kind of advice would you give to a person who wants a career in physics, despite not being accepted into grad school.
