Subscribe to my weekly science newsletter: https://sabinehossenfelder.com/ Everything I am talking about here is standard material of undergrad physics textbooks. My personal favorite is good old Goldstein https://en.wikipedia.org/wiki/Classic...) On variational principles more specifically I quite like this textbook: https://link.springer.com/book/10.100...
