Stephen Hawking fue un físico teórico y cosmólogo de renombre mundial cuyo trabajo alteró fundamentalmente nuestra comprensión del universo. Profundizó en las leyes fundamentales que rigen la realidad, tendiendo un puente entre la Teoría General de la Relatividad de Einstein y la mecánica cuántica. Las innovadoras teorías de Hawking sugieren que el espacio y el tiempo tuvieron un principio en el Big Bang, y que los agujeros negros podrían evaporarse. Su legado intelectual reside en desvelar los misterios más profundos del cosmos y cómo puede ser descrito por las leyes de la ciencia.
Además de proporcionarnos un ameno y, en ocasiones, divertido repaso de la historia de las Ciencias Físicas, Stephen Hawking formula en este libro una de las más atrevidas y brillantes propuestas científicas de las últimas décadas: unificar la teoría de la relatividad y la mecánica cuántica para crear una teoría cuántica de la gravedad que puede resumirse en que el Universo no necesita tener un principio ni un final, sería un universo eterno, finito pero sin fronteras y totalmente independiente.
Aun antes de aparecer, este libro ha venido precedido, en todos los medios de comunicación, de una extraordinaria polémica sobre sus conclusiones: que tanto nuestro universo como los otros muchos universos posibles surgieron de la nada, porque su creación no requiere de la intervención de ningún Dios o ser sobrenatural, sino que todos los universos proceden naturalmente de las leyes físicas. En efecto, este libro de Stephen Hawking y Leonard Mlodinow sobre los descubrimientos y los progresos técnicos más recientes nos presenta una nueva imagen del universo, y de nuestro lugar en él, muy distinta de la tradicional e, incluso, de la imagen que el propio Hawking nos había proporcionado, hace ya más de veinte años, en su gran libro Historia del tiempo. En él el gran físico nos explicaba de dónde procedía el universo y hacia dónde se encaminaba, pero aún no podía dar respuesta a importantes preguntas: ¿por qué existe el universo?, ¿por qué hay algo en lugar de nada?, ¿por qué existimos nosotros?, ¿necesita el universo un creador? En los últimos años, el desarrollo de la teoría “M” (en realidad toda una familia de teorías enlazadas sobre física cuántica) y las recientes observaciones realizadas por los satélites de la NASA, nos permiten ya enfrentarnos a la pregunta fundamental: la Cuestión Última de la Vida, el Universo y el Todo. Si esta teoría última es verificada por la observación científica, habremos culminado una búsqueda que se remonta a hace más de tres mil años: habremos hallado el Gran Diseño .
Einstein’s essay, On the Electrodynamics of Moving Bodies, introduces his famous “principle of relativity,” one of the twentieth century’s most revolutionary concepts. In his introduction to this seminal work, the renowned physicist Stephen Hawking cuts through Einstein’s mathematical complexities to explain this revolutionary concept in language that excites and informs the reader. This book features selections from a translation of the original essay, The Principle of Relativity, as well as an insightful biography of Einstein and Hawking’s informative summary.
“God does not play dice with the universe.” So said Albert Einstein in response to the first discoveries that launched quantum physics, as they suggested a random universe that seemed to violate the laws of common sense. This 20th-century scientific revolution completely shattered Newtonian laws, inciting a crisis of thought that challenged scientists to think differently about matter and subatomic particles.The Dreams That Stuff Is Made Of compiles the essential works from the scientists who sparked the paradigm shift that changed the face of physics forever, pushing our understanding of the universe on to an entirely new level of comprehension. Gathered in this anthology is the scholarship that shocked and befuddled the scientific world, including works by Niels Bohr, Max Planck, Werner Heisenberg, Max Born, Erwin Schrodinger, J. Robert Oppenheimer, Richard Feynman, as well as an introduction by today’s most celebrated scientist, Stephen Hawking.
Have you ever wondered how the universe began? Or what it takes to put humans on the moon - or even on Mars? What would you do if you could travel through space and time?Embark on the adventure of a lifetime in this beautiful collection of up-to-the-minute essays by the world's leading scientists including Professor Stephen Hawking himself, plus mind-blowing facts and out-of-this-world colour photographs.
The book was on the cutting edge of what was then known about the nature of the universe, but since that time there have been extraordinary advances in the technology of observing both the micro- and the macrocosmic worlds. These observations have confirmed many of Professor Hawking's theoretical predictions in the first edition of his book, including the recent discoveries of the Cosmic Background Explorer satellite (COBE), which probed back in time to within 300,000 years of the universe's beginning and revealed wrinkles in the fabric of space-time that he had projected. Eager to bring his original text the new knowledge revealed by these many observations, as well as his most recent research, for this expanded edition Professor Hawking has prepared a new introduction to the book, written an entirely new chapter on the fascinating subject of wormholes and time travel, and updated the original chapters. This edition is enhanced throughout with more than 240 full-color illustrations, including satellite images, photographs made possible by spectacular technological advances such as the Hubble Space Telescope, and computer-generated images of three and four dimensional realities
Inspire kids to ask the big questions about Earth and the cosmos with this stunningly illustrated version of Professor Stephen Hawking's final message to humankind. We are all time travelers journeying together into the future. But let us work together to make that future a place we want to visit. Scientist and educator Stephen Hawking spent his life trying to unravel the mysteries of the universe. But, he still had many questions—and he wanted every reader, every child, to come together to help answer them: How can we save the planet? How can we learn to be there for one another? Adapted from Professor Hawking’s posthumous 2020 Earth Day message, You and the Universe is his first picture book and is a tribute to the littlest citizens of Earth, highlighting the power of coming together and creating a better tomorrow.
Stephen Hawking explains how such great men of science as Copernicus, Galileo, Kepler, Newton and Einstein built on the discoveries of those who came before them, and how these works changed the course of science, ushering astronomy and physics out of the Middle Ages and into the modern world.
"It is said that fact is sometimes stranger than fiction, and nowhere is that more true than in the case of black holes. Black holes are stranger than anything dreamed up by science fiction writers." In 2016 Professor Stephen Hawking delivered the BBC Reith Lectures on a subject that has fascinated him for decades - black holes. In these flagship lectures the legendary physicist argues that if we could only understand black holes and how they challenge the very nature of space and time, we could unlock the secrets of the universe.
