This is the first book to show the development of Russian architecture over the past thousand years as a part of the history of Western architecture. Dmitry Shvidkovsky, Russia’s leading architectural historian, departs from the accepted notion that Russian architecture developed independent of outside cultural influences and demonstrates that, to the contrary, the influence of the West extends back to the tenth century and continues into the present. He offers compelling assessments of all the main masterpieces of Russian architecture and frames a radically new architectural history for Russia. The book systematically analyzes Russian buildings in relation to developments in European art, pointing out where familiar European features are expressed in Russian projects. Special attention is directed toward decorations based on Byzantine models; the heritage of Italian master builders and carvers; the impact of architects and others sent by Elizabeth I; the formation of the Russian Imperial Baroque; the Enlightenment in Russian art; and 19th- and 20th-century European influences. With over 300 specially commissioned photographs of sites throughout Russia and western Europe, this magnificent book is both beautiful and groundbreaking.

The Martians is the engaging story of five little-known Hungarian physicists who transformed 20th century science. They emigrated to the United States from Hungary in the 1930's, and were important contributors to such importants experiments as the Manhattan Project. Variously recognized with the National Medal for Science, the Presidential Medal of Freedom and the Nobel Prize for physics, these five remained close friends throughout their lives. Through decades of political and social upheaval, they held onto their Hungarian identities and were fiervely opinionated and politically active, reactionaries against the fascism and anti-Semitism with which they had grown up. Based on the author's personal relationships with the subjects and many interviews with their contemporaries, The Martians is an exhaustively researched, fascinating story of an important era in American, Hungarian, and scientific history.

The authors compare classical and quantum dynamics in the quasiclassical region of parameters and under the condition of unstable (chaotic) classical behavior. They estimate the characteristic time-scale at which classical and quantum solutions start to differ significantly. The method is based on exact equations for time-dependent expectation values in boson and spin coherent states, and applies to rather general Hamiltonians with many degrees of freedom. The authors develop a consistent dynamical theory for quantum nonintegrable Hamiltonians and provide explicit examples of classical-quantum "crossover-time," a very common and fundamental phenomenon in quantum nonintegrable systems. This book can be recommended to graduate students and to specialists.

Quantum Optics in Phase Space provides a concise introduction to the rapidly moving field of quantum optics from the point of view of phase space. Modern in style and didactically skillful, Quantum Optics in Phase Space prepares students for their own research by presenting detailed derivations, many illustrations and a large set of workable problems at the end of each chapter. Often, the theoretical treatments are accompanied by the corresponding experiments. An exhaustive list of references provides a guide to the literature. Quantum Optics in Phase Space also serves advanced researchers as a comprehensive reference book. Starting with an extensive review of the experiments that define quantum optics and a brief summary of the foundations of quantum mechanics the author Wolfgang P. Schleich illustrates the properties of quantum states with the help of the Wigner phase space distribution function. His description of waves ala WKB connects semi-classical phase space with the Berry phase. These semi-classical techniques provide deeper insight into the timely topics of wave packet dynamics, fractional revivals and the Talbot effect. Whereas the first half of the book deals with mechanical oscillators such as ions in a trap or atoms in a standing wave the second half addresses problems where the quantization of the radiation field is of importance. Such topics extensively discussed include optical interferometry, the atom-field interaction, quantum state preparation and measurement, entanglement, decoherence, the one-atom maser and atom optics in quantized light fields. Quantum Optics in Phase Space presents the subject of quantum optics as transparently as possible. Giving wide-ranging references, it enables students to study and solve problems with modern scientific literature. The result is a remarkably concise yet comprehensive and accessible text- and reference book - an inspiring source of information and insight for students, teachers and researchers alike.

The classical mechanistic idea of nature that prevailed during the eighteenth and nineteenth centuries was essentially mindless: the physically described aspects of nature were asserted to be completely determined by prior physically described aspects alone, with conscious experiences entering only passively. In the last century these classical concepts were found inadequate. In the new quantum mechanics theory, conscious experiences enter into the dynamics in specified ways not fixed by physically described aspects alone.

The authors explore the ways to improve the classical resolution limits of an imaging system, and provide novel approaches for achieving better results than would otherwise be possible with current imaging technology. The book begins by presenting the theoretical foundations, background information, and terminology of super resolution, and then discusses methods and systems used to achieve the super resolution effect. Various approaches to dealing with and exceeding the limitations of the lens aperture, the pixel size of the camera, and the noise generated at the detector are presented and analyzed. The last chapter illustrates several industry-related examples and potential applications to real industrial electro-optical systems. This book is intended for graduate students or researchers in academia or industry, and anyone else looking to improve the performance of their electro-optical system design.
