A lightning strike to an unprotected object or system can be disastrous - in the United States lightning is responsible for over 30% of all electric power failures, causes billions of dollars worth of property damage, and an average of 85 fatalities a year. This accessible text describes all aspects of lightning protection and includes many illustrative drawings and photographs. The author examines the physical behavior of lightning, various types of lightning damage, the role of lightning detection and warning in effective protection, as well as options for deflecting or eliminating lightning. U.S. and international lightning protection standards are discussed. This book will be essential reading for everyone involved in the business of lightning protection, including meteorologists, atmospheric scientists, architects, engineers, and fire-safety experts. Insurance practitioners and physicians will find this reference of significant value.

Superstrings - provocative, controversial, possibly untestable, but unarguably one of the most interesting and active areas of research in current physics. Called by some, "the theory of everything", superstrings may solve a problem which has eluded physicists for the past 50 years - the final unification of the two great theories of the twentieth century, general relativity and quantum field theory. Now, here is a course-tested comprehensive introductory graduate text on superstrings which stresses the most current areas of interest, not covered in other presentation, including: - string field theory - multi loops - Teichmueller spaces - conformal field theory - four-dimensional strings. The book begins with a simple discussion of point particle theory, and uses the Feynman path integral technique to unify the presentation of superstrings. Prerequisites are an aquaintance with quantum mechanics and relativity. This second edition has been revised and updated throughout.

Combustion, the process of burning, is defined as a chemical reaction between a combustible reactant (the fuel) and an oxidizing agent (such as air) in order to produce heat and in most cases light while new chemical species (e.g., flue gas components) are formed. This book covers a gap on the market by providing a concise introduction to combustion. Most of the other books currently available are targeted towards the experienced users and contain too many details and/or contain knowledge at a fairly high level. This book provides a brief and clear overview of the combustion basics, suitable for beginners and then focuses on practical aspects, rather than theory, illustrated by a number of industrial applications as examples. The content is aimed to provide a general understanding of the various concepts, techniques and equipment for students at all level as well as practitioners with little or no prior experience in the field. The authors are all international experts in the field of combustion technology and adopt here a clear didactic style with many practical examples to cover the most common solid, liquid and gaseous fuels. The associated environmental impacts are also discussed so that readers can develop an understanding of the major issues and the options available for more sustainable combustion processes. With a foreword by Katharina Kohse-Hoinghaus

This book presents theoretical methods and experimental results on the study of multipartite quantum correlations in spin-squeezed BoseEinstein condensates. Nonclassical correlations in many-body systems are particularly interesting for both fundamental research and practical applications. For their investigation, ultracold atomic ensembles offer an ideal platform, due to their high controllability and long coherence times. In particular, we introduce criteria for detecting and characterizing multipartite entanglement, EinsteinPodolskyRosen steering, and Bell correlations. Moreover, we present the experimental observation of such correlations in systems of about 600 atoms.

The handbook focuses on a complete outline of lithium-ion batteries. Just before starting with an exposition of the fundamentals of this system, the book gives a short explanation of the newest cell generation. The most important elements are described as negative / positive electrode materials, electrolytes, seals and separators. The battery disconnect unit and the battery management system are important parts of modern lithium-ion batteries. An economical, faultless and efficient battery production is a must today and is represented with one chapter in the handbook. Cross-cutting issues like electrical, chemical, functional safety are further topics. Last but not least standards and transportation themes are the final chapters of the handbook.The different topics of the handbook provide a good knowledge base not only for those working daily on electrochemical energy storage, but also to scientists, engineers and students concerned in modern battery systems.

This classic text provides a comprehensive exposition of the concepts and techniques of quantum mechanics. The phenomena treated are sufficiently simple to allow the student to readily assess the validity of the models so that attention is not deflected from the heart of the subject. To that end, the book concentrates on systems that can either be solved exactly or be handled by well-controlled, plausible approximations. With few exceptions, this means systems with a small number of degrees of freedom. The exceptions are many - electron atoms, the electromagnetic field and the Dirac equation. The inclusion of the last two topics reflects the belief that every physicist should now have some knowledge of these cornerstones of modern physics. This new edition has been completely revised and rewritten throughout, but retains the clarity and readability of the first edition.Born in Vienna, Kurt Gottfried emigrated to Canada in 1939 and received his Ph.D. in theoretical physics from the Massachusetts Institute of Technology in 1955.

El Universo esta formado por tres elementos básicos: Masa, que le da consistencia (Lo Tangible), Espacio, que le da volumen (Lo Intangible), y Energía, que le da Dinamismo. El resto son combinaciones cuantitativas de los tres. Considera esta Teoria como algo nuevo porque lo es. Presta atencion al leerla porque es algo muy importante, no es una novela. Teoria original basada en la logica y conocimientos actuales sobre el comportamiento de la MASA. La Teoria del Todo por Bepe Popu es una teoria del origen, presentando un mechanismo funcional del Universo, que se basa en la idea de que el espacio es una causa y no solo una separacion. Segun La Teoria, las masas absorben espacio, lo que genera trayectorias entrantes que se conoce como La Gravedad y desde este efecto se genera todos los efectos siguentes en el Universo. La gravedad es el efecto del espacio al ser absorbido por el componente Masa de las Masas. Esta Teoria es compatible con la ciencia tradicional, pero va mas alla. Explica los fenomenos que la ciencia no puede explicar, como el origen del Universo, Formacion y desarrollo del Universo, aparicion y comportamiento de la/s Masa, Espacio, Masas, Perspectivas, Dinamismo, Materia, Vida hasta el Conocimiento. Con base en los comportamientos presentados, es posible deducir TODO donde el Universo es solo una Etapa de un TODO Ciclico. Esta teoria niega el tiempo por ser solo una percepcion humana, en cambio, utiliza sucesiones de causas y efectos. Presenta Un Universo Finito y como resultado niega el Infinito o nada. El infinito en esta Teoria es solo el Limite Variable del Conocimiento en la etapa en que se emplea el termino y EL nada, solo es No Iniciado. CADA TEORIA ESTA SUJETA A APROBACION O DENEGACION, INCLUIDA ESTA. PERO HAY QUE COMPROBAR Y EXPERIMENTAR. Es una teoria original, una teoria del TODO como nunca ha existido, comienza antes de la aparicion del UNIVERSO y explica el caracter ciclico del TODO y da la logica, en esta teoria EL UNIVERSO es solo una ETAPA DEL TODO. No hay formulas, es una presentacion narrativa de la teoria y necesita ser estudiada, comprobada y experimentada. El libro es coleccionable, la teoria en si esta en Internet en su sitio web y es de lectura gratuita, el libro es coleccionable y no deben comprarlo si no se lo permite su condicion economica. Es una propuesta de estudio dedicada a todos los Seres Humanos pero en especial a los encargados del conocimiento del Universo.

he book is an introductory text to the physics of Bose-Einstein condensation. This phenomenon, first predicted by Einstein in 1925, has been realized experimentally in 1995 in a remarkable series of experiments whose importance has been recognized by the award of the 2001 Nobel Prize in Physics. The condensate is actually a new state of matter, where quantum-mechanical wave functions of atoms behave as coherent matter waves in the same way as coherent light waves in the case of a laser. The authors provide a theoretical presentation of the main concepts underlying the physics of dilute atomic gases in conditions of extremely low temperatures where quantum effects play a crucial role. The main effort is devoted to discussion of the relevant theoretical aspects exhibited by these systems, such as the concept of order parameter, long range order, superfluidity and coherence. The mathematical formalism is presented in a form convenient for practical use. The book develops the theory of Bose gases starting from the pioneering Bogoliubov approach and gives special emphasis to the new physical features exhibited by non-uniform gases which are produced in the recent experiments with magnetic and optical traps. These features include the determination of the equilibrium profiles, the collective oscillations, the mechanism of the expansion of the gas after releasing the trap, the interference patterns obtained by overlapping two condensates, the rotational properties revealing the effects of superfluidity (quantized vortices, behaviour of the moment of inertia), the Josephson-like phenomena associated with the coherence of the phase, the beyond mean field phenomena exhibited by quantum gases in conditions of reduced dimensionality (1D and 2D) etc. The book also discusses the analogies and differences with the physics of "classical" superfluids like liquid helium and introduces some of the major features of trapped Fermi gases at low temperature, pointing out the consequences of superfluidity.

he International System of Units (SI) is the world's most widely used system of measurement, used every day in commerce and science, and is the modern form of the metric system. It currently comprises the meter (m), the kilogram (kg), the second (s), the ampere (A), the kelvin (K), the candela (cd) and the mole (mol)). The system is changing though, units and unit definitions are modified through international agreements as the technology of measurement progresses, and as the precision of measurements improves. The SI is now being redefined based on constants of nature and their realization by quantum standards. Therefore, the underlying physics and technologies will receive increasing interest, and not only in the metrology community but in all fields of science. This book introduces and explains the applications of modern physics concepts to metrology, the science and the applications of measurements. A special focus is made on the use of quantum standards for the realization of the forthcoming new SI (the international system of units).The basic physical phenomena are introduced on a level which provides comprehensive information for the experienced reader but also provides a guide for a more intense study of these phenomena for students.

This book provides a comprehensiveoverview of the theory and practical development of metamaterial-based perfectabsorbers (MMPAs). It begins with a brief history of MMPAs whichreviews the various theoretical and experimental milestones in theirdevelopment. The theoretical background and fundamental working principles ofMMPAs are then discussed, providing the necessary background on how MMPAs workand are constructed. There then follows asection describing how different MMPAs are designed and built according to theoperating frequency of the electromagnetic wave, and how theirbehavior is changed. Methods of fabricating and characterizing MMPAs are thenpresented.
