Che cosa succederebbe se Simplicio, Salviati e Sagredo, i tre protagonisti del "Dialogo" di Galileo, si incontrassero oggi e parlassero di fisica? Come reagirebbero all'ancora insuperato scandalo del comportamento quantistico della materia? Un grande fisico contemporaneo, Jauch, ha avuto l'idea di mettere in scena questo gioco, sulle rive del lago di Ginevra. E cosi ha scritto una guida illuminante e leggibile ai temi cruciali della fisica contemporanea.

Revving engines, smoking tires, and high speeds. Car racing enthusiasts and race drivers alike know the thrill of competition, the push to perform better, and the agonyand dangersof bad decisions. But driving faster and better involves more than just high horsepower and tightly tuned engines. Physicist and amateur racer Chuck Edmondson thoroughly discusses the physics underlying car racing and explains just whats going on during any race, why, and how a driver can improve control and ultimately win. The world of motorsports is rich with excitement and competitionand physics. Edmondson applies common mathematical theories to real-world racing situations to reveal the secrets behind successful fast driving. He explains such key concepts as how to tune your car and why it matters, how to calculate 0 to 60 mph times and quarter-mile times and why they are important, and where, when, why, and how to use kinematics in road racing. He wraps it up with insight into the impact and benefit of green technologies in racing. In each case, Edmondsons in-depth explanations and worked equations link the physics principles to qualitative racing advice. From selecting shifting points to load transfer in car control and beyond, Fast Car Physics is the ideal source to consult before buckling up and cinching down the belts on your racing harness.

Se recogen los trabajos presentados en esta cita, realizados por primerísimas autoridades mundiales en diferentes campos de la Física y donde se muestra parte de la actividad científica de nuestro pais, desde los aspectos mas fundamentales de la cosmologia y la fisica fundamental a la nanotecnologia, optica, informacion cuantica, plasmas o aplicaciones medicas, entre otros.

Covering all aspects of gravitation in a contemporary style, this advanced textbook is ideal for graduate students and researchers in all areas of theoretical physics. The 'Foundation' section develops the formalism in six chapters, and uses it in the next four chapters to discuss four key applications - spherical spacetimes, black holes, gravitational waves and cosmology. The six chapters in the 'Frontier' section describe cosmological perturbation theory, quantum fields in curved spacetime, and the Hamiltonian structure of general relativity, among several other advanced topics, some of which are covered in-depth for the first time in a textbook. The modular structure of the book allows different sections to be combined to suit a variety of courses. Over 200 exercises are included to test and develop the reader's understanding. There are also over 30 projects, which help readers make the transition from the book to their own original research.

Este libro traslada al lector una imagen del mundo diferente, la que ofrece la física de nuestro tiempo.Desde hace más de tres cuartos de siglo, sabemos que la naturaleza está regida por las leyes que determina una teoria fisica en muchos aspectos paradojica y contraintuitiva: la fisica cuantica. Sin apenas matematicas, situando aquello que se trata en un contexto historico, y utilizando unas atractivas ilustraciones que destacan las principales ideas que aparecen en el, este libro,La realidad cuantica, presenta los fundamentos de la mecanica cuantica. Su objetivo primero es explicar los desconcertantes conceptos de superposicion, colapso y entrelazamiento, que sostienen el edificio cuantico. Recurriendo a experimentos, los autores, dos destacados investigadores en esa rama de la fisica, van desvelando, de un modo intuitivo, esos conceptos, explicando, asimismo, resultados fundamentales como los producidos por John Bell, que precipitaron la caida del mundo determinista defendido por Einstein. Una vez establecida esa base teorico-experimental, y siguiendo el mismo procedimiento intuitivo, los autores presentan las modernas aplicaciones de esos conceptos cuantico: teleportacion, criptografia y ordenadores cuanticos. Todas ellas se enmarcan en la Teoria de la Informacion Cuantica, una disciplina tras la que se esconden importantes interrogantes que tambien se tratan aqui, tales como si la informacion es suficiente para interpretar correctamente la mecanica cuantica, o si el mundo se explicaria, en ultimo termino, como informacion.
