I'm studying computer engineering which requires me to take the fundamentals concepts of physics (classical mechanics, electromagnetism, optics, and a bit of modern physics). I have truly found a passion for physics throughout my studies of these topics, although unfortunately I don't have to take any more physics after I finish with optics. I was thinking that I should continue studying physics independently (maybe as a hobby, just to keep feeding my curiosity). However, I don't know where to start. What should be the order of physics that I should take next? What good books would you guys recommend me to buy for them? Thanks.
