A middle-aged salaryman wishing to do Physics Ph.D. after retirement

My math sucked in high school so I chose not to do physics in college. Did Economics instead. I had kept reading popular books but felt deeply unsatisfied.

The only good thing coming out of COVID is the abundance of online material on advanced physics supplied by prominent physicists. So I think it was time I should start to self-study physics seriously.

My current reading list:
Weinberg, Gravitation and Cosmology (now in Chapter 3)
Peter Woit, Quantum Theory, Groups, and Representations (now in Chapter 10)
Weinberg, The Quantum Theory of Fields, Volume 1 (now in Chapter 2)
Michel Talagrand, What is a Quantum Field Theory? (now in Chapter 3)

It seems to me your are trying to read some advanced physics stuff for someone that doesn't have good mathematical background. I think the third book by Weinberg requires pretty advanced math.
