I will start undergrad next year (majoring in Physics). I am very interested in classical physics especially electrodynamics, thermodynamics, and Relativity. I want to explore them and possible come up with new ideas. I also have an interest in Quantum theory and Astrophysics; however, I am more interested in electrodynamics thermodynamics, and Relativity. I know they are classical but I am very interested in them. Should I focus on them or focus on the new theories. Would I be a classical physicist?
