Hi, I would like to ask HOW you become a theoretical physicist. By how, I mean what classes are needed? What is college like for one studying to become a theoretical physicist?I would like to specialize in Relativity and Quantum Mechanics. Of course this all depends on what college you attend and though I'm not entirely sure, MIT, Harvard, Princeton, and Cambridge are optional schools for me. I say this because I am enrolled in the STEM program and though it doesn't ensure that I would be accepted into these colleges it does improve my chances. If anyone has any questions feel free to ask and thank you very much for answering my question.
