I'm about to enter University for a Chemistry major, but I've been throwing around the idea of a double major and also taking Mathematics. They do not offer a physics major, but it's my understanding that physics is heavily reliant on advanced math and that physics itself is so hard because many lack the mathematical understanding. If I were to take this road, would there be a significant learning curve if I tried to pursue a graduate education in physics? I'm currently reading through the Feynman lectures to get an introduction to a physics undergrad, but I'm unsure of what standards have been set for a student pursuing graduate school. I've heard of the physics GRE, but I'm not too familiar. I understand that it involves Classical Mechanics, Electromagnetism, Thermodynamics, Quantum Mechanics, and many other areas of Physics. Areas that neither a Chem or Math major would cover. Which is why I'm concerned about taking my current path. Anyone have some insight?
