Key topics for the second year of a 'Maths for Physics' module typically include linear algebra and calculus, which are essential for understanding advanced physics concepts. Recommended resources include the book linked, which covers necessary mathematical foundations for physics majors, and supplementary texts like Gilbert Strang's linear algebra book for deeper understanding. For classical mechanics, Landau and Lifgarbagez's series is highly regarded, particularly for its treatment of Lagrangian and Hamiltonian mechanics. Students are encouraged to explore M. Boas' Mathematical Methods book for a comprehensive overview of relevant topics in a concise format. Additionally, for upcoming modules on statistical physics, resources on statistical mechanics and entropy are suggested, including Stanford's lecture videos.
