¿Cuánto calor hace en Venus? ¿Cuál es la diferencia entre un púlsar y un cuásar? ¿Hay un universo, o un multiverso? ¿Qué lugar nos corresponde dentro del esquema infinitamente grande de las cosas? ¿Como se cartografia el fondo cosmico de microondas? Y lo mas atractivo de todo: ¿hay alguien mas ahi fuera? En este libro hallara las respuestas a estas y muchas otras cuestiones de la ciencia moderna. Todos observamos el cielo, pero el viaje por los contenidos estelares de este libro dejara gratamente sorprendido a cualquiera. Una obra que concentra la pavorosa inmensidad del cosmos en pequeños bocados comprensibles para meros terricolas. El firmamento nocturno es la parte mas universal de nuestro entorno. A lo largo de la historia, la gente ha contemplado la misma boveda celeste, aunque cada cultura la haya interpretado a su manera. Desde los babilonios se han registrado patrones en los movimientos planetarios. La necesidad de contar con un calendario preciso y de navegar por los oceanos conllevo avances en la medicion del tiempo, la optica y las matematicas. De hecho, la astronomia siempre ha espoleado la tecnologia. Y, gracias a telescopios inmensos, sondas y computadoras avanzadas, la comunidad astronomica actualha descubierto el asombroso panorama cosmico que se describe en este libro. 50 descubrimientos increibles que descienden a la Tierra en no mas de dos paginas, unas 300 palabras y una imagen. Este pequeño volumen ofrece una gira por el cosmos que arroja luz sobre los objetos y lugares mas formidables, porque explica grandes ideas, conceptos y descubrimientos, y presenta a los cientificos y observadores que han trabajado tanto para esclarecer la vida, el universo y el todo. Bienvenidos a bordo.

The Encyclopedia of Thermal Stresses is an important interdisciplinary reference work. In addition to topics on thermal stresses, it contains entries on related topics, such as the theory of elasticity, heat conduction, thermodynamics, appropriate topics on applied mathematics, and topics on numerical methods. The Encyclopedia is aimed at undergraduate and graduate students, researchers and engineers. It brings together well established knowledge and recently received results. All entries were prepared by leading experts from all over the world, and are presented in an easily accessible format. The work is lavishly illustrated, examples and applications are given where appropriate, ideas for further development abound, and the work will challenge many students and researchers to pursue new results of their own. This work can also serve as a one-stop resource for all who need succinct, concise, reliable and up to date information in short encyclopedic entries, while the extensive references will be of interest to those who need further information. For the coming decade, this is likely to remain the most extensive and authoritative work on Thermal Stresses.

This excellent and novel scientific work has given an area of key research a significant step forward. The systematic documentation of the approach to describing phase transitions will facilitate further applications of the theory to important problems. | A thermodynamically consistent description of the transport across interfaces in mixtures has for a long time been an open issue. This research clarifies that the interface between a liquid and a vapor in a mixture is in local equilibrium during evaporation and condensation. It implies that the thermodynamics developed for interfaces by Gibbs can be applied also away from equilibrium, which is typically the case in reality. A description of phase transitions is of great importance for the understanding of both natural and industrial processes. For example, it is relevant for the understanding of the increase of CO2 concentration in the atmosphere, or improvements of efficiency in distillation columns. This excellent work of luminescent scientific novelty has brought this area a significant step forward. The systematic documentation of the approach will facilitate further applications of the theoretical framework to important problems.

#1 "NEW YORK TIMES" BESTSELLER When and how did the universe begin? Why are we here? What is the nature of reality? Is the apparent "grand design" of our universe evidence of a benevolent creator who set things in motion--or does science offer another explanation? In this startling and lavishly illustrated book, Stephen Hawking and Leonard Mlodinow present the most recent scientific thinking about these and other abiding mysteries of the universe, in nontechnical language marked by brilliance and simplicity. According to quantum theory, the cosmos does not have just a single existence or history. The authors explain that we ourselves are the product of quantum fluctuations in the early universe, and show how quantum theory predicts the "multiverse"--the idea that ours is just one of many universes that appeared spontaneously out of nothing, each with different laws of nature. They conclude with a riveting assessment of M-theory, an explanation of the laws governing our universe that is currently the "only" viable candidate for a "theory of everything" the unified theory that Einstein was looking for, which, if confirmed, would represent the ultimate triumph of human reason.

For junior/senior-level electricity and magnetism courses.This book is known for its clear, concise, and accessible coverage of standard topics in a logical and pedagogically sound order. The highly polished Fourth Edition features a clear, easy-to-understand treatment of the fundamentals of electromagnetic theory, providing a sound platform for the exploration of related applications (AC circuits, antennas, transmission lines, plasmas, optics, etc.). Its lean and focused approach employs numerous new examples and problems. Features The book features a friendly, informal style.Focuses clearly on basic electromagnetic theory, providing a sound platform for future exploration of related applications (such as AC circuits, antennas, transmission lines, plasmas, optics, etc.). A large collection of problems includes short, highly-focused problems that are placed immediately following the relevant text section while longer/more broadly-based problems are at the end of the chapter. Features a more extensive coverage of radiation theory than most texts at this level. Zum Seitenanfang New to this Edition Edits to the entire text have clarified arguments and eliminated ambiguities. New problems and new worked examples appear throughout, while selected unsuccessful ones have been eliminated. All 450 figures have been reviewed for accuracy and updated where necessary. A new section on magnetic work helps to eliminate teachers misconception that magnetic forces do not work.The new section fully explores the actual mechanism in cases where magnetic forces are actually working. Erroneous passages have been corrected. In particular, misleading copy (specifically the treatment of hidden momentum) has been fixed. Citations of recent literature appear throughout for those who wish to pursue a particular topic in greater depth. This literature helps reinforce the point that electrodynamics is a vibrant and dynamic field, even after 150 years.

Atoms, Radiation, and Radiation Protection offers professionals and advanced students a comprehensive coverage of the major concepts that underlie the origins and transport of ionizing radiation in matter. Understanding atomic structure and the physical mechanisms of radiation interactions is the foundation on which much of the current practice of radiological health protection is based. The work covers the detection and measurement of radiation and the statistical interpretation of the data. The procedures that are used to protect man and the environment from the potential harmful effects of radiation are thoroughly described. Basic principles are illustrated with an abundance of worked examples that exemplify practical applications. Chapters include problem sets (with partial answers) and extensive tables and graphs for continued use as a reference work. This completely revised and enlarged third edition includes thorough updates of the material, including the latest recommendations of the ICRP and NCRP.

Estas observaciones sobre la ciudad de Lima contienen una descripción topográfica de Lima, un examen de la calidad del suelo, naturaleza de sus aguas, influencia del sol o de la luna, eclipses, estado de la atmósfera. En la segunda parte del libro se examina la influencia que tiene el clima en la vegetación y la constitución del cuerpo humano. El autor procura explicarlo todo sin adherirse a un particular sistema fisiológico ni botánico, sino deduciéndolo de los hechos y observaciones.
