The discussion centers on the feasibility of self-learning physics to a Ph.D. level, particularly in quantum physics and relativity, given personal constraints like previous academic failures and financial limitations. Participants emphasize that while self-study is possible, achieving a deep understanding of physics typically requires formal education due to the importance of mentorship, research experience, and structured learning. Suggested starting points include mastering basic physics and calculus through recommended textbooks and online resources. The value of community college courses and online platforms like MIT OpenCourseWare is highlighted as viable options for those unable to pursue traditional degrees. The conversation also touches on the intrinsic motivation for learning physics, with participants encouraging the pursuit of knowledge for personal fulfillment rather than solely for credentials. Overall, while self-study can provide substantial knowledge, the consensus is that interaction with instructors and peers is crucial for mastering complex concepts and conducting research.
