Hi, My name is Sebastian, and I'm new to this whole community. I know absolutely nothing about physicsforums.com and would like to have some basic information to get me started here. My general goal here (on physicsforums.com not on this specific thread) is to learn from people with years of experience in the field of physics about books, courses, recourses and advice in general that truly shaped their insights and careers. I am a senior in high school. Thank you very much in advanced, Sebastian.
