Описание: The developer of path integrals, Nobel Prize-winning physicist Richard Feynman, presents unique insights into this method and its applications. Feynman starts with an intuitive view of fundamental quantum mechanics, gradually introducing path integrals. Later chapters explore more advanced topics, including the perturbation method, quantum electrodynamics, and statistical mechanics. 1965 edition, emended in 2005.

Описание: Combining art and science, this indispensable reference focuses on the skeleton's impact on the external form and the attachments of the muscular system. Over 70 accurate illustrations -- standing and in motion -- cover everything from the neck, head, trunk, limbs, hand, and foot to details of the face.
Written for students in search of a single-volume account of both the methods used in dealing with the many-body problem and the physics that result, this book is not an advanced treatment, but nevertheless assumes a good basic understanding of elementary quantum mechanics. Beginning with single-body approximations, the authors go on to devote full chapters to atoms and molecules, second quantization, many-body perturbation theory, Fermi fluids, nuclear matter, superconductivity, many-boson systems, grand partition functions, and Green functions. Each chapter contains an introduction and a selection of well-chosen problems, while a series of helpful appendixes deals with such topics as the second quantized form of one-particle operators, Wick's theorem, the loop theorem, ring diagrams, the time-dependent Hartree-Fock theory of electron gas, and other matters. A carefully selected list of references rounds out this comprehensive text on an important area of theoretical physics.
Tired of doing the same basic stitches over and over again? Noted designer Hope Hanley can help you bring new excitement and beauty to your needlepoint in more than a hundred different ways. In this practical, extremely well-organized guide she presents a treasury of 101 decorative stitches, with an easy-to-read chart and an actual-size photograph for each one. Only stitches which adequately cover the canvas have been included in this versatile collection. In Tapestry no warp threads are allowed to show through, so why let canvas show in needlepoint? Enhance and individualize your needlepoint projects with expert advice on a host of exquisite stitches: rep stitch; fancy cross stitch; Renaissance stitch; cross stitch; Herringbone stitch; shaded stripe stitch; double stitch; mosaic stitch; French stitch; Greek stitch; velvet stitch; closed cat stitch; and scores more. The author explains precisely where and how to make best use of each stitch (as a filling stitch in small areas, as a background or a grounding pattern), and tells whether each is slow or quick to work up and whether it's best on mono or two-thread canvas. No stitch combinations have been included, just the fundamental stitch. Think up your own combinations -- there are hundreds of them Whether you're a beginner, intermediate, or advanced needleworker, give your needlepoint a vibrant new look with this modestly priced, indispensable reference work.
