To effectively engage with Susskind's Stanford lectures on general relativity (GR), a foundational understanding of special relativity (SR) is essential, especially for those without prior exposure to the subject. It is advisable to start with Susskind's series on special relativity before progressing to his GR lectures. Supplemental reading can enhance comprehension; recommended texts include Geroch's book, which, while accessible, requires careful thought, and another suggested book that may provide valuable insights. Additionally, a solid grasp of linear algebra is beneficial, as it underpins many concepts in physics. Engaging with Susskind's broader series, from classical mechanics to cosmology, can also provide a comprehensive foundation for understanding advanced topics.
