This comprehensive and modern presentation of theoretical physics is a treasure trove for advanced students and professional physicists facing theoretical-physical problems. This volume covers the traditional material of classical mechanics; however, it is presented with a focus on modern physics in both its presentation and selection of applications. In addition to the general theory (Lagrangian and Hamiltonian formalism), applications to important concrete and modern examples (Kepler problem, particle decay, collisions and scattering, Rutherford formula, molecular vibrations, resonance, gyroscopes) are discussed. The conservation laws are given due emphasis. The presentation is characterized by physically intuitive reasoning while maintaining formal rigor. The addition of... is very valuable.
