Stephen Hawking Livres

Voilà vingt ans, Stephen Hawking nous passionnait avec sa Brève histoire du temps et s'intéressait déjà aux questions les plus fondamentales: que savons-nous de l'Univers? Comment sommes-nous parvenus à cette connaissance? D'où vient l'Univers et où va-t-il ? Questions éternelles et toujours plus captivantes à mesure que se précisent les connaissances scientifiques. S'appuyant sur les plus récentes observations et les dernières avancées théoriques, il nous raconte aujourd'hui les progrès accomplis en cosmologie et en physique des particules. Il nous fait partager le fruit de ses dernières réflexions dans une histoire qu'il destine à tous. Il nous invite à cheminer pas à pas, éclairant les différentes tentatives d'explication de l'Univers, de la théorie de la gravitation de Newton à la relativité d'Einstein, en passant par l'accélération de l'expansion de l'Univers, les trous noirs, la possibilité ou l'impossibilité des voyages dans le temps. La théorie des cordes, qui tente d'unifier les quatre forces de la Nature, constitue le point d'orgue de son histoire. Mais laissons-lui le dernier mot: "Mon but, écrit-il, est de vous faire partager non seulement toute l'excitation que ces découvertes provoquent, mais aussi la nouvelle image de la réalité qui en découle."

Le jour où Georges rencontre ses nouveaux voisins - la jeune Annie et son scientifique de père, Éric - il est loin d'imaginer ce qu'il va vivre. Le garçon découvre chez eux un secret qui va bouleverser sa vision du monde... Éric possède Cosmos, l'ordinateur le plus perfectionné qui soit, dont la super-intelligence peut projeter Georges et ses amis aux quatre coins de l'Univers ! Alors, explorer l'immensité de l'espace, frôler des planètes, traverser une tempête d'astéroïdes devient un jeu d'enfant... Hélas, quelqu'un nourrit de sombres projets pour Cosmos ! Et, quand on sait qu'il n'y a rien de plus dangereux dans l'espace qu'un trou noir, Georges et Éric ont bien du souci à se faire...

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.
