This question already has an answer here:
I am currently a second year. I'm thinking about going to condensed matter physics grad school, but I don't know what degree combination would be the best. Does physics + chemistry sound like a good choice? I saw that many people going to physics grad school have a math degree. But I already run out of class slots to be a math + physics double major. I'm also afraid that physics grad school would not appreciate a chemistry degree.
I do have an interest in math. But I somehow feel that the math for physicists/chemists(specifically physical chemists) is a little different from that for mathematicians. Does it mean that physicists/chemists just pick up math along the way in their own fields? Which means I don't need to major in math in order to do physics research in grad school?
