Do you have experience or interest in the works of Landau and Lifshitz in physics or mathematics?

I am familiar with the main ideas and works of Landau and Lifshitz, especially their classic textbook on theoretical physics, which covers a wide range of topics from mechanics to quantum field theory. Their approach to systematizing knowledge and rigorous mathematical formalization has had a significant influence on the development of physics and mathematics. In terms of practical experience, I have used some methods from their works when solving problems in mechanics and electrodynamics.
