Landau's Course of Theoretical Physics is considered too brief and lacking in pedagogical depth for those seeking a solid foundation in physics, especially for undergraduate students. A strong mathematical background, including calculus, differential equations, and linear algebra, is essential to navigate the series effectively. Alternatives like Calkin's "Lagrangian & Hamiltonian Mechanics" and Morin's classical mechanics are recommended for their clarity and problem sets. The discussion emphasizes the need for a survey book that balances technical rigor with accessibility, as many existing options shy away from detailed explanations. Overall, a solid grasp of mathematics is crucial for understanding the complexities of theoretical physics.
