As the title suggests, I am looking for an online source for self studying physics. I am also interested in mathematics so if there is something for this to I am very interested. I want to learn it in university level. now I need classical mechanics but I believe in the future more advanced topics will be required. I've already purchased some old books online, waiting for them to arrive, but I will be happy to hear about something similar to MIT OpenCourseWare to watch some lectures or videos with good explanations. I used Khan Academy for a few days but it's not exactly what I was looking for... I also heard about edX. do you recommend any of these? or do you know about other sites which can help me?

  • $\begingroup$ May I ask why Khan Academy was not what you were seeking? $\endgroup$

  • $\begingroup$ Maybe I just felt it's not enough... Good for introducing new concepts, or sharpening old ones, but without something else (for example a textbook) this is not working for me... That is why I am looking for texts (if you know about any cheap ones from amazon this would be helpful, old editions are totally ok) $\endgroup$ Feb 4 '19 at 20:27
  • $\begingroup$ David Tong's lecture notes are a treasure trove of resources. They're mostly in the text form, however, they cover a lot of material and will be useful until you're in grad school. $\endgroup$
