I have a B.S. in Mechanical Enginerring and I am almost done with a PhD in Nanotechnology. Through these years I realized I really like physics and I would like to learn mmore advanced physics than the one I know so far. I would like to know how to study physics. My plan is to follow the academic program for a physics major and read all the books they read. I just started by reading the lower division courses books. Does anybody has any suggestions?
