The final sections on adiabatic invariants have been revised and augmented. In addition a short biography of L D Landau has been inserted.

Comprised of 16 chapters, this volume begins with an overview of non-relativistic quantum theory and the basic concepts of quantum mechanics such as the principles of uncertainty and superposition, operators, and the density matrix. Subsequent chapters deal with conservation laws in quantum mechanics; Schrödinger's equation and general properties of its solutions; perturbations independent of time and dependent on time; spin and the spin operator; and the principle of indistinguishability of similar particles. The atom and its electron states are also examined, together with diatomic molecules; elastic and inelastic collisions; photons and electrons; Dirac's equation; and particles and antiparticles. The final chapter is devoted to Feynman diagrams, paying particular attention to the scattering matrix, radiative corrections, and radiative shift of atomic levels.

This book is comprised of 16 chapters and begins with an overview of the fundamental equations of fluid dynamics, including Euler's equation and Bernoulli's equation. The reader is then introduced to the equations of motion of a viscous fluid; energy dissipation in an incompressible fluid; damping of gravity waves; and the mechanism whereby turbulence occurs. The following chapters explore the laminar boundary layer; thermal conduction in fluids; dynamics of diffusion of a mixture of fluids; and the phenomena that occur near the surface separating two continuous media. The energy and momentum of sound waves; the direction of variation of quantities in a shock wave; one- and two-dimensional gas flow; and the intersection of surfaces of discontinuity are also also considered.

This compelling book offers readers with no technical expertise beyond arithmetic an enlightening tour of the paradoxes inherent in the special theory of relativity, guided by a pair of eminent theoretical physicists.

Novel Prize physicist L. D. Landau and his distinguished colleague G. B. Rumer, employ a simple and straightforward manner to illuminate relativity theory's more subtle and elusive aspects. Using such familiar objects as trains, rulers, and clocks, the authors explain the reasoning behind seemingly self-contradictory ideas in which the relative seems absolute, but the absolute proves to be relative. A series of playful cartoons highlights the authors' witty observations on the laws governing inertia, the speed of light, the relationship of work and mass, and other relativistic concepts.

"The exposition is masterful . . . a superb book." — New York Times Book Review.

This volume deals with the properties of gases, the thermodynamics of a degenerate plasma, liquid crystals, the fluctuation theory of phase transitions, and critical phenomena. Other chapters discuss the topics of solids, symmetry of crystals, and the theory of rreducible representations of space groups as applied to physics of the crystal state. This volume also explores the fluctuation-dissipation theorem; the Fermi and Bose distributions; non-ideal gases; phase equilibrium; and solutions.

This book is of great value to theoretical physicists, researchers, and students.
