Stephen Hawking, página 3 de 8

Hawking se pregunta de dónde surgió el cosmos, si hubo un principio en el tiempo o si el Universo es infinito. En Historia del tiempo hay revelaciones sobre las fronteras de la física, la astronomía... y el valor. Tambien Hawking intenta, el mismo asi lo dice, comprender el pensamiento de Dios, y repasas las teorias desde Aristoteles hasta nuestros dias.

Una manera clara y amena de acercarse a los misterios del universo. En esta esclarecedora obra, el gran físico británico Stephen Hawking nos ofrece una historia del universo, del big bang a los agujeros negros. En siete pasos, Hawking logra explicar la historia del universo, desde las primeras teorias del mundo griego y de la epoca medieval hasta las mas complejas teorias actuales, siempre con su caracteristico tono didactico y accesible a todos los publicos. Newton, Einstein, la mecanica cuantica, los agujeros negros y la teoria de la gran unificacion desfilan por estas paginas acercando al lector los misterios del universo. Reseña:"Un libro exquisito. En definitiva, autentica poesia del infinito."Leer

Stephen Hawking, author of the multi-million copy bestselling A Brief History of Time, and his daughter Lucy explain the universe to readers of all ages. George''s parents, who have always been wary of technology, warn him about their new neighbors: Eric is a scientist and his daughter, Annie, seems to be following in his footsteps. But when George befriends them and Cosmos, their super-computer, he finds himself on a wildly fun adventure, while learning about physics, time, and the universe. With Cosmos''s help, he can travel to other planets and a black hole. But what would happen if the wrong people got their hands on Cosmos? George, Annie, and Eric aren''t about to find out, and what ensues is a funny adventure that clearly explains the mysteries of science. Garry Parsons'' energetic illustrations add humor and interest, and his scientific drawings add clarity; there are also eight 4-page full-color inserts of scientific photos.

Stephen Hawking, uno de los pensadores más influyentes de nuestro tiempo, se ha convertido en un icono intelectual no sólo por la osadía de sus ideas científicas, sino también por la claridad y agudeza con que sabe expresarlas. En este libro, Hawking nos conduce hasta la frontera misma de la fisica teorica -donde la verdad supera muchas veces a la ficcion para explicarnos en terminos verdaderamente sencillos, y en ocasiones muy divertidos, los principios que rigen nuestro universo. Con su peculiar entusiasmo, el profesor Hawking nos incita a acompañarle en un colosal viaje por el espacio-tiempo, hacia un increible pais de las maravillas en el que particulas, membranas y cuerdas danzan en once dimensiones, donde los agujeros negros se evaporan y desaparecen llevandose consigo su secreto, y donde habita la pequeña nuez -la semilla cosmica originariade la que surgio nuestro universo. El universo en una cascara de nuez es imprescindible para cuantos deseamos comprender el universo en que vivimos. Como ya sucedio con la Historia del tiempo, el nuevo libro de Hawking nos ilumina y nos conmueve porque a traves de su lectura experimentamos tambien nosotros la misma emocion que embarga a la comunidad cientifica a medida que va arrancando al cosmos sus secretos.

Stephen Hawkings phenomenal, multimillion-copy bestseller, A Brief History of Time, introduced the ideas of this brilliant theoretical physicist to readers all over the world. Now, in a major publishing event, Hawking returns with a lavishly illustrated sequel that unravels the mysteries of the major breakthroughs that have occurred in the years since the release of his acclaimed first book. One of the most influential thinkers of our time, Stephen Hawking is an intellectual icon, known not only for the adventurousness of his ideas but for the clarity and wit with which he expresses them. In this new book Hawking takes us to the cutting edge of theoretical physics, where truth is often stranger than fiction, to explain in laymens terms the principles that control our universe. Like many in the community of theoretical physicists, Professor Hawking is seeking to uncover the grail of science the elusive Theory of Everything that lies at the heart of the cosmos. In his accessible and often playful style, he guides us on his search to uncover the secrets of the universe from supergravity to supersymmetry, from quantum theory to M-theory, from holography to duality. He takes us to the wild frontiers of science, where superstring theory and p-branes may hold the final clue to the puzzle. And he lets us behind the scenes of one of his most exciting intellectual adventures as he seeks to combine Einsteins General Theory of Relativity and Richard Feynmans idea of multiple histories into one complete unified theory that will describe everything that happens in the universe. With characteristic exuberance, Professor Hawking invites us to be fellow travelers on this extraordinary voyage through space-time. Copious four-color illustrations help clarify this journey into a surreal wonderland where particles, sheets, and strings move in eleven dimensions; where black holes evaporate and disappear, taking their secret with them; and where the original cosmic seed from which our own universe sprang was a tiny nut.

BRAND NEW PAPERBACK (B FORMAT) (1184 pages) helps the reader understand the progression of mathematical thought, and the very foundations of technologies. this book includes landmark discoveries spanning 2500 years and representing the work of mathematicians such as euclid, georg cantor, kurt godel, augustin cauchy, bernard riemann and alan turing.

Stephen Hawkings worldwide bestseller, A Brief History of Time, has been a landmark volume in scientific writing. Its authors engaging voice is one reason, and the compelling subjects he addresses is another: the nature of space and time, the role of God in creation, the history and future of the universe. But it is also true that in the years since its publication, readers have repeatedly told Professor Hawking of their great difficulty in understanding some of the books most important concepts. This is the origin of and the reason for A Briefer History of Time: its authors wish to make its content more accessible to readers as well as to bring it up-to-date with the latest scientific observations and findings. Although this book is literally somewhat briefer, it actually expands on the great subjects of the original. Purely technical concepts, such as the mathematics of chaotic boundary conditions, are gone. Conversely, subjects of wide interest that were difficult to follow because they were interspersed throughout the book have now been given entire chapters of their own, including relativity, curved space, and quantum theory. This reorganization has allowed the authors to expand areas of special interest and recent progress, from the latest developments in string theory to exciting developments in the search for a complete unified theory of all the forces of physics. Like prior editions of the bookbut even more soA Briefer History of Time will guide nonscientists everywhere in the ongoing search for the tantalizing secrets at the heart of time and space.

HISTORIA DEL TIEMPO es un libro de divulgación sobre el espacio y el tiempo escrito por uno de los físicos teóricos más prestigiosos de la actualidad. En él STEPHEN W. HAWKING presenta de forma clara y concisa los conceptos fundamentales de la mecanica newtoniana, la teoria de la relatividad, la mecanica cuantica y la cosmologia contemporanea, temas todos ellos que, junto a su interes intrinseco, permiten enmarcar el problema de fondo tratado en el libro: el origen del universo y la creacion del espacio-tiempo, llegando a asomarse a campos mas amplios y aventurados, como la metafisica e incluso la teologia, al plantearse la naturaleza de Dios creador, o mas bien garante del sentido del universo.

Desde Einstein, y sobre todo a partir de su teoría de la relatividad general, sabemos que los fenómenos naturales tienen lugar en un marco geometrico de cuatro dimensiones, en el espaciotiempo. En este libro algunos de los fisicos y divulgadores cientificos mas importantes de nuestro tiempo exploran las posibilidades mas llamativas que nos abre el espaciotiempo einsteiniano. Tras una excelente introduccion, en la que Richard Price suministra las herramientas conceptuales basicas para poder comprender que es eso que llamamos "espaciotiempo", Igor Novikov introduce a los lectores en las posibilidades de los viajes en el tiempo con sencillas explicaciones y modelos que evitan las tipicas paradojas que se producen cuando el viaje conduce a tiempos anteriores al de partida. Sin embargo, los viajes en el tiempo son, tal vez, imposibles porque pueden violar leyes fisicas que aun no hemos descubierto: esta es la cuestion que aborda Stephen Hawking con su maestria habitual. Por su parte, Kip Thorne mira a un futuro en el que se pueda comprobar una de las predicciones de la teoria de la relatividad general, la de la radiacion gravitacional, que ha desafiado hasta el momento todos los intentos de ser detectada, mientras que Alan Lightman y Timothy Ferris abordan aspectos mas "externa
