Hi, I'm 15 years old, and I'm sure I want to be a physicist. I was wondering if I could get advice on what steps I should be taking right now. Should I start looking for internships? If so, what are good places to go in the U.S.? (Please don't just say NASA). Also, what's the whole internship process like? How can I have a good chance of getting into somewhere? What classes should I take before the end of high school? What are good colleges to go to if I want to major in physics?
