Описание: Is design intuitive or is it consciously and methodically worked out? Are there basic rules governing design that, when learned, will facilitate the creative process? These questions have been asked by artists, art historians, and art critics throughout the ages. Convinced that design was not purely instinctive, Jay Hambidge (1867-1924) spent much of his life searching for the technical bases of design. He found his answer in dynamic symmetry, one of the most provocative and stimulating theories in art history. Hambidge's study of Greek art convinced him that the secret of the beauty of Greek design was in the conscious use of dynamic symmetry -- the law of natural design based upon the symmetry of growth in man and in plants. But Hambidge, who was not only a theoretician but also a practicing artist, did much more than analyze classical art and its principles of design: he worked out a series of root rectangles that the artist, using the simple mathematics supplied in this book, can easily follow and apply in his own work. Originally published as a series of lessons in Hambidge's magazine, The Diagonal, this engrossing book explains all the basic principles of dynamic symmetry. Part I sets forth the fundamental rectangles with their simple divisions based on the proportioning law found in nature; Part II explains compound rectangles, many of which were taken from or suggested by analysis of objects of Greek art. Whether read for its historical importance in art theory, for its illuminating insights into Greek art, or for its practical value to today's artists and commercial designers, The Elements of Dynamic Symmetry has much to offer anyone who is interested in the principle of design.

Описание: "The authors use an informal but highly effective writing style to present a uniform and consistent treatment of the subject matter." -- Journal of Chemical Education. The primary focus of this text is to introduce students to vibrational and electronic spectroscopy, presenting applications of group theory to the interpretation of UV, visible, and infrared spectra without assuming a high level of background knowledge. The text is divided into five chapters that address the fundamentals of group theory, qualitative aspects of quantum mechanics, vibrational spectroscopy, molecular orbital theory, and electronic spectroscopy. To make the exposition clear and meaningful, each new concept is applied or illustrated with experimental results as quickly as possible. In addition, each chapter features a large number of relevant problems through which students can test their understanding of text material. These problems are an integral part of the text and sometimes introduce new material. Solutions to the problems (often accompanied by detailed explanations) can be found in an appendix. Carefully written to provide a solid foundation in spectroscopic analysis, the book devotes significant attention to the interpretation and significance of vibrational and electronic spectra, including good introductory material on Raman and photo-electron spectroscopy, vibronic analysis, and transition metal complexes. Moreover, many of the concepts presented clearly here can be easily extended to studies in other fields of chemistry. Also included are numerous helpful figures and line drawings illustrating important concepts.
"What makes Gardner so appealing is his ease in exploring deep ideas . . . and making them accessible to the interested but nontechnical reader. This is a special talent and no one has ever displayed it quite as well as he does." -- Los Angeles Times "Absorbing; enlightening; lucid; witty; inventive. An exemplar of science writing at its very best." -- American Mathematical Monthly A substantial revision of Martin Gardner's earlier well-known work on mirror symmetry and asymmetry, The New Ambidextrous Universe takes readers on an extraordinary journey. With Gardner's guidance, they explore the two fundamental scientific discoveries of the past century: the asymmetric DNA helix and the overthrow of parity (left-right symmetry) in particle physics. Along the way, students will find absorbing and thought-provoking treatments of some of the deepest mysteries in modern physics. Author of more than 60 books, Martin Gardner has influenced and inspired generations of scientists, scholars, and other readers, especially those with an interest in mathematics. He originated Scientific American's popular Mathematical Games column, which he wrote from 1956 until his retirement from the magazine three decades later. This republication of his revised edition of an earlier work features a new appendix of notes and corrections.
