The book of authors from the USA is designed to teach the reader to simulate physical experiments on a computer (and thereby teach physics). All chapters of the second part are related to statistical physics and quantum mechanics. Each chapter contains theoretical material, methods for solving relevant problems, program texts, tasks and test questions. The authors share their experience of using a computer to study a wide class of physical problems from the fall of bodies in the field of gravity of the Earth, vibrations, the simplest problems of thermal conductivity to such modern sections as chaos in dynamical systems, percolation problems, the renormalization group method and the study of polymers by random walk.
