This 1977 volume is celebrated as one of the most elegant and accessible single-volume introductions to theoretical physics ever published in the Soviet Union. Boris Medvedev (1924–2000), a distinguished student of Nikolai Bogoliubov, possessed a rare talent for distilling the most complex concepts of modern physics into a clear, pedagogical narrative without sacrificing mathematical rigor.
The book is structured to lead the reader through the natural evolution of physical thought: starting with Lagrangian and Hamiltonian mechanics, moving into classical and relativistic field theory, and concluding with the foundations of quantum mechanics. Unlike the more exhaustive multi-volume courses, Medvedev’s "Foundations" emphasizes the unity of physical laws and the transition from classical to quantum descriptions. It has served as a "desk reference" for generations of Soviet experimentalists and engineers, praised for its clarity on subjects like perturbation theory and spin. For collectors and scholars, this "Nauka" edition represents the pinnacle of late-century scientific pedagogy.
