W. Patrick McCray,Every night, astronomers use a new generation of giant telescopes at observatories around the world to study phenomena at the forefront of science. By focusing on the history of the Gemini Observatorytwin 8-meter telescopes located on mountain peaks in Hawaii and ChileGiant Telescopes tells the story behind the planning and construction of modern scientific tools, offering a detailed view of the technological and political transformation of astronomy in the postwar era. Drawing on interviews with participants and archival documents, W. Patrick McCray describes the ambitions and machinations of prominent astronomers, engineers, funding patrons, and politicians in their effort to construct a modern facility for cutting-edge scienceand to establish a model for international cooperation in the coming era of "megascience." His account details the technological, institutional, cultural, and financial challenges that scientists faced while planning and building a new generation of giant telescopes. Besides exploring how and why scientists embraced the promise and potential of new technologies, he considers how these new tools affected what it means to be an astronomer. McCray's book should interest anyone who desires a deeper understanding of the science, technology, and politics behind finding our place in the universe.

Dernière édition parue pour le centenaire des Editions Flammarion en 1976.Le Fac-similé de l'édition originale de 1879 accompagné d'une postface de J.-C. Pecker, président de la Société Astronomique de France, directeur de l'Institut d'Astrophysique, présente cette édition en ces termes : « A côté de publications modernes exposant les résultats de la science d'aujourd'hui (et dont la validité sera toujours plus éphémère, les connaissances progressant à une vitesse fantastique, toujours plus grande), il était nécessaire, à nos yeux, de publier en fac-similé la première édition de l'Astronomie populaire de Camille Flammarion, celle de 1879, celle qui, pour des générations, faisait le point sur la science du ciel : on y rencontrera un enthousiasme admirable pour le ciel, et aussi cette sorte de joyeux dévouement à la diffusion des idées, dont nous pouvons regretter qu'il soit plus aussi efficace aujourd'hui qu'alors. Pour tous, cette joie d'enseigner, cette volupté de connaître devraient nous rester un modèle permanent... »

Esta obra se ha dividido en dos partes: Parte 1, "Introducción a la Relatividad y a la Física cuántica" y Parte 2, "Aplicaciones". Los capítulos de la Parte 2 son completamente independientes entre sí y pueden desarrollarse en cualquier orden. Un curso de un solo semestre comprenderá probablemente 41 la mayor parte de los temas de la Parte 1 y varios capítulos (o, al menos, parte de ellos) de la Parte 2.

Esta Introducción a la Física del estado sólido, es un texto para alumnos avanzados de Ciencias e Ingeniería que han de iniciarse en el tema. Es el texto más citado dentro de su campo. En él se estudian las propiedades que resultan de la distribucion de los electrones en los metales, semiconductores y aislantes. Tambien se nos dice como comprender las excitaciones elementales e imperfecciones de los solidos, cuya potencia y utilidad estan firmemente establecidos en la actualidad.

Superconducting quantum circuits are among the most promising solutions for the development of scalable quantum computers. Built with sizes that range from microns to tens of metres using superconducting fabrication techniques and microwave technology, superconducting circuits demonstrate distinctive quantum properties such as superposition and entanglement at cryogenic temperatures. This book provides a comprehensive and self-contained introduction to the world of superconducting quantum circuits, and how they are used in current quantum technology. Beginning with a description of their basic superconducting properties, the author then explores their use in quantum systems, showing how they can emulate individual photons and atoms, and ultimately behave as qubits within highly connected quantum systems. Particular attention is paid to cutting-edge applications of these superconducting circuits in quantum computing and quantum simulation. Written for graduate students and junior researchers, this accessible text includes numerous homework problems and worked examples.

Con el objetivo de reflejar las nuevas investigaciones y los métodos de enseñanza de la física más recientes, esta edición ha sido actualizada completamente. Los cambios varían de la inclusión de elementos recien descubiertos en la tabla periodica a la adicion de ejercicios nuevos en cada capitulo. Ademas, se han agregado nuevos“Ejercicios de version multiple” a formarse una comprension conceptual, a aprender a relacionar las cantidades fisicas diferentes y a reconocer problemas.

This book is an exposition of semi-Riemannian geometry (also called pseudo-Riemannian geometry)--the study of a smooth manifold furnished with a metric tensor of arbitrary signature. The principal special cases are Riemannian geometry, where the metric is positive definite, and Lorentz geometry. For many years these two geometries have developed almost independently: Riemannian geometry reformulated in coordinate-free fashion and directed toward global problems, Lorentz geometry in classical tensor notation devoted to general relativity. More recently, this divergence has been reversed as physicists, turning increasingly toward invariant methods, have produced results of compelling mathematical interest.
