Available in PDF, EPUB and Kindle. Book excerpt: This new, third volume of Cohen-Tannoudji's groundbreaking textbook covers advanced topics of quantum mechanics such as uncorrelated and correlated identical particles, the quantum theory of the electromagnetic field, absorption, emission and scattering of photons by atoms, and quantum entanglement. Written in a didactically unrivalled manner, the textbook explains the fundamental concepts in seven chapters which are elaborated in accompanying complements that provide more detailed discussions, examples and applications. * Completing the success story: the third and final volume of the quantum mechanics textbook written by 1997 Nobel laureate Claude Cohen-Tannoudji and his colleagues Bernard Diu and Franck Laloë * As easily comprehensible as possible: all steps of the physical background and its mathematical representation are spelled out explicitly * Comprehensive: in addition to the fundamentals themselves, the books comes with a wealth of elaborately explained examples and applications Claude Cohen-Tannoudji was a researcher at the Kastler-Brossel laboratory of the Ecole Normale Supérieure in Paris where he also studied and received his PhD in 1962. In 1973 he became Professor of atomic and molecular physics at the Collège des France. His main research interests were optical pumping, quantum optics and atom-photon interactions. In 1997, Claude Cohen-Tannoudji, together with Steven Chu and William D. Phillips, was awarded the Nobel Prize in Physics for his research on laser cooling and trapping of neutral atoms. Bernard Diu was Professor at the Denis Diderot University (Paris VII). He was engaged in research at the Laboratory of Theoretical Physics and High Energy where his focus was on strong interactions physics and statistical mechanics. Franck Laloë was a researcher at the Kastler-Brossel laboratory of the Ecole Normale Supérieure in Paris. His first assignment was with the University of Paris VI before he was appointed to the CNRS, the French National Research Center. His research was focused on optical pumping, statistical mechanics of quantum gases, musical acoustics and the foundations of quantum mechanics.
Download or read book Terra 2008 written by Leslie Rainer and published by Getty Publications. This book was released on 2011-06-14 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earthen architecture constitutes one of the most diverse forms of cultural heritage and one of the most challenging to preserve. It dates from all periods and is found on all continents but is particularly prevalent in Africa, where it has been a building tradition for centuries. Sites range from ancestral cities in Mali to the palaces of Abomey in Benin, from monuments and mosques in Iran and Buddhist temples on the Silk Road to Spanish missions in California. This volume's sixty-four papers address such themes as earthen architecture in Mali, the conservation of living sites, local knowledge systems and intangible aspects, seismic and other natural forces, the conservation and management of archaeological sites, research advances, and training.

Download or read book Organic Solid State Lasers written by Sébastien Forget and published by Springer. This book was released on 2013-07-03 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organic lasers are broadly tunable coherent sources, potentially compact, convenient and manufactured at low-costs. Appeared in the mid 60’s as solid-state alternatives for liquid dye lasers, they recently gained a new dimension after the demonstration of organic semiconductor lasers in the 90's. More recently, new perspectives appeared at the nanoscale, with organic polariton and surface plasmon lasers. After a brief reminder to laser physics, a first chapter exposes what makes organic solid-state organic lasers specific. The laser architectures used in organic lasers are then reviewed, with a state-of-the-art review of the performances of devices with regard to output power, threshold, lifetime, beam quality etc. A survey of the recent trends in the field is given, highlighting the latest developments with a special focus on the challenges remaining for achieving direct electrical pumping of organic semiconductor lasers. A last chapter covers the applications of organic solid-state lasers.

Download or read book The Rhetoric of Religion written by Kenneth Burke and published by Univ of California Press. This book was released on 1970-04 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: "But the point of Burke's work, and the significance of his achievement, is not that he points out that religion and language affect each other, for this has been said before, but that he proceeds to demonstrate how this is so by reference to a specific symbolic context. After a discussion 'On Words and The Word,' he analysess verbal action in St. Augustine's Confessions. He then discusses the first three chapters of Genesis, and ends with a brilliant and profound 'Prologue in Heaven,' an imaginary dialogue between the Lord and Satan in which he proposes that we begin our study of human motives with complex theories of transcendence,' rather than with terminologies developed in the use of simplified laboratory equipment. . . . Burke now feels, after some forty years of search, that he has created a model of the symbolic act which breaks through the rigidities of the 'sacred-secular' dichotomy, and at the same time shows us how we get from secular and sacred realms of action over the bridge of language. . . . Religious systems are systems of action based on communication in society. They are great social dramas which are played out on earth before an ultimate audience, God. But where theology confronts the developed cosmological drama in the 'grand style,' that is, as a fully developed cosmological drama for its religious content, the 'logologer' can be further studied not directly as knowledge but as anecdotes that help reveal for us the quandaries of human governance." --Hugh Dalziel Duncan from Critical Responses to Kenneth Burke, 1924 - 1966, edited by William H. Rueckert (Minneapolis: University of Minnesota Press, 1969).

Download or read book Pit and Fissure Sealants written by Katrin Bekes and published by Springer. This book was released on 2018-02-27 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides wide-ranging information on current clinical and scientific knowledge on the various aspects of fissure sealing. Trends in the epidemiology of caries are first examined, followed by thorough description of the morphology of pits and fissures and types of sealant. The role of sealants in the prevention of caries is discussed. Diagnostic parameters are presented, along with step-by-step descriptions of clinical procedures for fissure sealing. Chapters are also included on alternative techniques of fissure sealing, sealing of carious fissures, and therapeutic fissure sealing. The final chapter in the book focuses on the cost effectiveness of the procedure. Tooth surfaces with pits and fissures are particularly vulnerable to caries development. Sealants were developed to help manage these sites of the tooth and safeguard the surfaces from decay. This book has been written by acknowledged experts in the field. It will be of value for all dental professionals seeking to deepen their understanding of current knowledge on the science and the clinical application of pit and fissure sealants.
