The popular introductory course in theoretical physics covers all the essential areas for the diploma across seven volumes. Each volume thoughtfully provides the necessary theoretical and physical tools for the respective semester. Numerous exercises with detailed solutions serve to deepen the understanding of the material. The second volume addresses mechanics in the Lagrangian, Hamiltonian, and Hamilton-Jacobi formulations. This new edition has been fundamentally revised and supplemented. The two-color presentation allows for a very clear and quick access to the teaching material.
