Описание: Illustrated with interesting examples from everyday life, this text shows how to create ellipses, parabolas, and hyperbolas and presents fascinating historical background on their ancient origins. The text starts with a discussion of techniques for generating the conic curves, showing how to create accurate depictions of large or small conic curves and describing their reflective properties, from light in telescopes to sound in microphones and amplifiers. It further defines the role of curves in the construction of auditoriums, antennas, lamps, and numerous other design applications. Only a basic knowledge of plane geometry needed; suitable for undergraduate courses. 1993 edition. 98 figures.

"Coherent and lucid...a valuable summary of a subject to which the authors] have made significant contributions by their own research." -- Contemporary Physics Offering an admirably clear account of the basic principles behind all quantum optical resonance phenomena, and hailed as a valuable contribution to the literature of nonlinear optics, this distinguished work provides graduate students and research physicists probing fields such as laser physics, quantum optics, nonlinear optics, quantum electronics, and resonance optics an ideal introduction to the study of the interaction of electromagnetic radiation with matter. The book first examines the applicability of the two-level model for atoms to real atoms, then explores semiclassical radiation theory, and derives the optical Bloch equations. It then examines Rabi inversion, optical nutation, free-induction decay, coherent optical transient effects, light amplification, superradiance, and photon echoes in solids and gases. Before the publication of this book, much of the material discussed was widely scattered in other books and research journals. This comprehensive treatment brings it together in one convenient resource. The style of writing is clear and informal and the emphasis throughout is always on the physics of the processes taking place. There are numerous helpful illustrations, excellent introductions to each chapter, and lists of references for further reading. "The authors have endeavored to create a primer for the field of optical resonance...they have succeeded admirably. Their coverage of the subject is remarkably complete." -- IEEE Journal of Quantum Electronics

Описание: The 746 designs contained in this volume represent some of the most ingenious and attractive applications of geometrical and optical motifs to be found today. Taken from an authentic, modern Japanese work, they are an intriguing new source of unique design elements for artists, designers, and illustrators. The designs employ circles, dots, squares, ellipses, curves, lines, angles, complete alphabets, and numbers in a seeming infinitude of balance, asymmetry, repetition, harmony, swirl, and mathematical exactitude. Some seem to recede, advance, shimmer, and dazzle in the manner of Op Art; others fool the eye with wholly unexpected shifts in focus; still others start with a basic theme and either develop remarkable variations or repeat the same element almost endlessly. But all, from the smallest design to those that take a full page, fascinate and delight. This book is an inexhaustible source of novel, appealing, and striking design elements for advertising campaigns, packaging, display, industrial use, crafts, textiles, and similar fields. These designs may be used as they are, or cropped, enlarged, reduced, repeated, rearranged, combined, screened, superimposed, cut apart, overlaid, or otherwise employed. All illustrators, designers, crafters, and commercial and graphic artists will find this collection immensely usable and the individual designs extremely effective.
