This two-volume book systematically lays out the basics of physics on a more modern basis than is commonly accepted. The questions of mechanics are organically related to the theory of relativity and the uncertainty relation. Conservation of Energy , momentum and angular momentum? with the principles of symmetry of space and time, fundamentals of thermodynamics ? with molecular statistics and the structure of matter, hydromechanics ? with the theory of shock waves . The second volume of "Fundamentals of Physics" deals with: vibrational and wave processes, including optics, modern ideas about the physics of atoms, molecules, solids and their most important properties. All sections of the second volume, as well as the first, are organically connected by the theory of relativity and quantum mechanics. The reader is required only a thorough knowledge of physics, algebra and the beginning of trigonometry in the volume of the eight-year school. However, this is not a book for entertaining reading, working on it will require serious efforts from the reader. The book is intended for high school students. It can also be useful for teachers of physics of schools and technical schools and students of universities .
