I will be transferring to UCLA in the fall as a chemistry major (with physical chemistry concentration) and intend to pursue physical chemistry in graduate school afterward and have a few questions about pursuing physics alongside chemistry: -Physics is such an interesting field (particularly particle physics) and I feel like I'll be missing out if I don't pursue it at all past lower division courses. Would double majoring be a good idea or a waste of time (and effort)? -If I finished my chemistry degree and decided that I'd rather pursue physics, could I study physics in graduate school with a chemistry degree (plus a good background in physical chemistry and maybe having taken a few upper division physics courses and education from self study)? -Since pursuing a bachelor's in physics might not be an option for me, I was thinking I could perhaps purchase some books and teach myself about some of the topics covered in upper division physics classes. Does anyone on here have any experience with self-taught physics?
