Great Book!
This is such a great book that collected almost all well evaluated data in my research field. It's very helpful for me. The problem is, it's too expensive. Anyway, my boss buy one and I can share with him. ... Read more

Product Description
The Dirac Equation is a modern presentation of the relativistic quantum mechanics of electrons intended to make new mathematical results accessible to a wider audience. It treats in some depth the relativistic invariance of a quantum theory, self-adjointness and spectral theory, qualitative features of relativistic bound and scattering states, and the external field problem in quantum electrodynamics, without neglecting the interpretational difficulties and limitations of the theory. A novel feature is the extensive use of supersymmetric quantum mechanics in the discussions of, e.g. the nonrelativistic limit, Fredholm and Witten indices, the relativistic Coulomb problem, particles with anomalous moments, behaviour in the presence of magnetic fields, and soliton theory. The book is aimed at scientists and graduate students interested in quantum mechanics who want to learn about the mathematical foundations, the physical interpretation and important applications of Dirac's electron theory. ...

Product Description
Physics and astronomy are favorite topics among the general public as the popularity of Stephen W. Hawking's "A Brief History of Time" indicates. Popular works on physics and astronomy that entertain as they translate scientific principles, discoveries, and theories into common language are a main reason why these sciences remain favorite topics. "Popular Physics and Astronomy" provides general readers with an essential resource to this growing and important body of literature, many of which have been written by the leading lights of these disciplines. The 895 books, articles, and nonprint media are divided by subject and include chapters devoted to the history of physics, basic principles, books for children and young adults, and audiovisual presentations. Each entry contains annotations that describe the general level of mathematics used in the book, the writer's qualifications, the presence of visual aids, and evaluative comments. ... Read more

Product Description

This index is a guide to organic compounds which have material constants of general interest described in the Landolt-Börnstein / New Series. In total in the subvolumes G, H and I, 15775 compounds with 16123 references to numerical data are recorded (I: 6141 compounds). Compiled are volumes containing nuclear magnetic resonance (NMR) data for different isotopes (chemical shifts and coupling constants).

Product Description
This work might have been entitled The Introduction of Planck's Constant into Mathematics, in that it introduces quantum conditions in a purely mathematical way in order to remove the singularities that arise in obtaining approximations to solutions of complex differential equations.

The book's first chapter develops the necessary mathematical apparatus: Fourier transforms, metaplectic and symplectic groups, the Maslov index, and lagrangian varieties. The second chapter orders Maslov's conceptions in a manner that avoids contraditions and creates step by step an essentially new structure-the lagrangian ayalysis.

Unexpectedly and strangely the last step requires the datum of a constant, which in applications to quantum mechanics is identified with Planck's constant. The final two chapters apply lagrangian analysis directly to the Schrödinger, the Klein-Gordon, and the Dirac equations. Magnetic field effects and even the Paschen-Back effect are taken into account.

Jean Leray-who has been professor at the Collège de France for the past thirty years-has made fundamental contributions to theoretical hydrodynamics, to the study of elliptic, hyperbolic, and analytic linear and nonlinear equations, and to algebraic topology and its applications to analysis. His motivations always had their origin in physical problems, except during World War II: As a prisoner of war in Germany for five years, he concealed his interest in mathematical applications by making fruitful investigations in the field of pure algebraic topology. ...
