I think I might try to restart my attempt at physics, though I will do it on my own rather than go through a college. So I went looking for some recommendations. Here’s one really long list, from basic mechanics through quantum field theory and general relativity, susanjfowler.com. I can skip the calculus book, since I have practiced that twice with my oldest two kids. But I’ll have to squeeze it in with studying machine learning, Spanish, and raising a 16 year old, who is struggling with a subpar physics teacher.
