Hamiltonian Dynamics Theory and Applications
As a matter of fact, in his memoir and in the M´ethodes Nouvelles Poincar´e seems to end up with different conclusions. Just to mention a few results of his work, let me recall the theorem on generic non–existence of first integrals, the recurrence theorem, the divergence of classical perturbation series as a typical fact, the discovery of asymptotic solutions and the existence of homoclinic points.

Guide to Electric Power Generation
Like water, food, and air, electrical energy has become an integral part of daily personal and business lives. People have become so accustomed to fl icking a switch and having instant light, action, or communication that little thought is given to the process that produces this electrical energy or how it gets to where it is used. It is unique in that practically all that is produced is not stored but used instantly in the quantities that are needed. For alternatives to electrical energy, one must go back to the days of gas lamps, oil lamps, candles, and steam- or water-powered mechanical devices—and work days or leisure time that was limited to daylight hours for the most part.

LIGHT AND DARK
This book brings together a wide range of topics that would normally be found in separate texts classified as astronomy, zoology, technology, history, art or physics. The connection is the theme of light and dark, which may alternate either in time or in space. In the time domain, slow variations often determine when animals mate and sleep, patterns defined in seconds provide navigational information for sailors and flashes of almost incomprehensible brevity convey messages and data around the world. Spatial patterns in black and white define the area on which chess players compete and enable the computer at the supermarket checkout to distinguish baked beans from jam tarts.

GRAVITATION AND COSMOLOGY: PRINCIPLES AND APPLICATIONS OF THE GENERAL THEORY OF RELATIVITY
Now that this book is done I can look back, and identify two purposes which led me to begin writing, and which have guided the work to completion. One good practical purpose was to bring together and assess the wealth of data provided over the last decade by new techniques in experimental physics and in optical, radio, radar, X-ray, and infrared astronomy. Of course, new data will keep coming in even as the book is being printed, and I cannot hope that this work will remain up to date forever. I do hope, however, that by giving a comprehensive picture of the experimental tests of general relativity and observational cosmology, I will help to prepare the reader (and myself) to understand the new data as they emerge. I have also tried to look a little way into the future, and to discuss what may be the next generation of experiments, especially those based on artificial satellites of the earth and sun.

Designing with light: The art, science and practice of architectural lighting design
Lighting is an essential element in any well-designed space, and Designing with Light: The Art, Science, and Practice of Architectural Lighting Design offers students and professionals a hands-on resource for applying the proven principles and most recent technologies during all stages of the design process. Designing with Light is a comprehensive introduction to the thoughtful and aesthetic use of lighting to define and enhance a space. Written in an accessible style, this resource explores all aspects of the lighting design process, including information on the basic principles of lighting, the aesthetics involved, current trends in lighting technology, the psychology of light, and more. The book is filled with illustrative color examples that demonstrate the real-world effects of the concepts outlined. In addition, there is a companion website that contains video animations and challenging exercises that illuminate the art and science of lighting. Written by Jason Livingston, a noted lighting designer and instructor, Designing with Light contains lively discussions on color, light, and health, as well as the latest data on energy efficient lighting, control systems, and other technological advances. Designing with Light also includes information on building and energy codes, as well as guidance on photometrics and calculations. This resource contains the principles, strategies, and science that can empower lighting designers to create simple and elegant spaces, or work on more complex and demanding projects.

Geometry, Topology and Physics
This book is a considerable expansion of lectures I gave at the School of Mathematical and Physical Sciences, University of Sussex during the winter term of 1986. The audience included postgraduate students and faculty members working in particle physics, condensed matter physics and general relativity. The lectures were quite informal and I have tried to keep this informality as much as possible in this book. The proof of a theorem is given only when it is instructive and not very technical; otherwise examples will make the theorem plausible. Many figures will help the reader to obtain concrete images of the subjects.

GEOMETRIC OPTICS
Geometrical optics is both the object of abstract study and a body of knowledge necessary for design and engineering . The subject of geometric optics is small , since so much can be derived from a single principle , that of Fermat , and large since the consequences are infinite and far from obvious . Geometric optics is deceptive in that much that seems simple is loaded with content and implications , as might be suggested by the fact that some of the most basic results required the likes of Newton and Gauss to discover them . Most of what appears complicated seems so because of obscuration with mathematical terminology and excessive abstraction . Since it is so old , geometric optics tends to be taken for granted and treated too casually by those who consider it to be ‘‘understood . ’’ One consequence is that what has been long known can be lost if it is not recirculated by successive generations of textbook authors , who are pressed to fit newer material in a fairly constant number of pages

История кристаллографии (с древнейших времен до начала XIХ столетия)
В книге рассмотрены два начальных этапа развития кристаллографии. Первый, начинающийся с беглых замечаний о кристаллах в древнегре-ческой и римской литературе и кончающийся основополагающими трудами II. Стенова и Э. Бартолина, соответствует периоду зарождения науки. Второй этап — это период становления науки, он характеризуется трудами М. А. Канеллера, К. Линнея, Ж. Л. Бюффона, М. В. Ломоносова и завершается достижениями Ж. Б. Ромэ-Делиля и Р. Ж. Гаюи, заложившими прочный фундамент развития современной кристаллографии.
