After 1905, Einstein''s miraculous year, physics would never be the same again. In those twelve months, Einstein shattered many cherished scientific beliefs with five extraordinary papers that would establish him as the world''s leading physicist. This book brings those papers together in an accessible format. The best-known papers are the two that founded special relativity: "On the Electrodynamics of Moving Bodies" and "Does the Inertia of a Body Depend on Its Energy Content?" In the former, Einstein showed that absolute time had to be replaced by a new absolute: the speed of light. In the second, he asserted the equivalence of mass and energy, which would lead to the famous formula "E = mc2," The book also includes "On a Heuristic Point of View Concerning the Production and Transformation of Light," in which Einstein challenged the wave theory of light, suggesting that light could also be regarded as a collection of particles. This helped to open the door to a whole new world--that of quantum physics. For ideas in this paper, he won the Nobel Prize in 1921.

Esta guía escrita por un observador lunar experto y afamado, constituye una obra práctica elemental para quienes aspiren a observar la Luna. Tanto los principiantes como los experimentados en astronomia practica encontraran en esta obra una gran ayuda para pasar a un nivel superior y avanzar mas alla. En esta segunda edicion, el autor incorpora las ultimas novedades tecnicas para tomar imagenes lunares, entre las que se incluyen la fotografia digital, las imagenes con CCD y la observacion con webcam. Entre las ventajas fundamentales del libro se cuentan su enfoque practico y su combinacion de fotografias vistosas con mapas y cartas esclarecedores.

Presenting the fundamental concepts of meteorology in the context of everyday weather observations, this text blends theory and application in meteorology. The book features a traditional yet flexible organization, moving from atmospheric elements to air movement to severe weather, then finally global and climate change. Ahren''s successfully excites the student reader by teaching them to actively observe the weather.

Graduate students who want to become familiar with advanced computational strategies in classical and quantum dynamics will find here both the fundamentals of a standard course and a detailed treatment of the time-dependent oscillator, Chern-Simons mechanics, the Maslov anomaly and the Berry phase, together with many worked examples throughout the text.This new edition has been revised and enlarged with chapters on the action principle in classical electrodynamics, on the functional derivative approach, and on computing traces.
