• Fascinantes sont les règles du monde quantique. Elles nous disent qu'un chat peut être mort et vivant à la fois et qu'une particule peut se trouver à deux endroits en même temps. Depuis près d'un siècle, les meilleurs esprits se heurtent à ces mystères. Or, appliquée, la physique quantique est à l'origine de certaines des plus grandes avancées de la science : les lasers, le gps, bientôt l'ordinateur quantique à la puissance de calcul incomparable... Les scientifiques font donc face à ce dilemme : continuer à effectuer des équations quantiques sans en chercher la signification ou tenter de déchiffrer la réalité qu'elles recouvrent.

    Par son talent de vulgarisateur, John Gribbin nous plonge dans le monde de l'infiniment petit à la découverte des six principales interprétations des grands physiciens qui ont relevé le défi de décoder la réalité quantique. Dans ce voyage au sein de la matière invisible, nous revivons les expériences d'Einstein, de Feynman, de Schrödinger... Leurs interprétations sont impossibles d'après le sens commun, et pourtant... Le monde n'existerait-il pas sauf quand nous le regardons ? Tout ce qui pourrait arriver est-il déjà arrivé et nous n'en aurions remarqué qu'une partie ? À vous à présent d'en décider.

  • La mécanique quantique permet de comprendre la réalité. Grâce au paradoxe mis en avant par le scientifique Schrödinger, prenant pour exemple un chat, l'auteur montre que la vision de la réalité n'a cessé d'évoluer depuis Newton en passant par Einstein et que, plus récemment, pour la mécanique quantique seul ce qui est observé est réel.

  • Quels points communs entre un séisme, un embouteillage et les tacites du léopard? ente la firme d'une fougère et celle des côtes de Norvége? entre la naissance d'une tornade et l'apparition de la vie? Tous ces phénomènes se caractérisent par une complexité qui a longtemps laissé la science traditionnelle perplexe.
    C'est seulement dans les années 1970 qu'elle leur trouva un début d'explication: la théorie du chaos était née. Souvent incompréhensible pour les non-scientifiques, ou jugée contradictoire avec la science classique, cette théorie repose sur deux idées simples: l'hypersensibilité de certains systèmes 3 leurs conditions initiales et les rétroactions qui accompagnent parfois leur évolution. Contrairement à ce qui a été trop souvent dit, la théorie du chaos ne remet pas en question les lois de Newton.
    Les récentes avancées montrent même qu'elle permet d'éclairer les comportements a priori inexplicables de la météo, des marchés boursiers, des séismes, des populations Véritable révolution clans notre façon de comprendre et d'interpréter la science contemporaine, cette théorie a mené les chercheurs à deux doigts de percer l'ultime mystère : l'origine de la vie. C'est ce que nous explique John Gribbin, en relatant avec une pédagogie et orle clarté remarquables quatre siècles de découvertes scientifiques, de la mécanique classique à la biologie moléculaire, de Galilée à James Lovelock.

  • Ce Grand Livre de l'astronomie nous fait voyager de la Terre aux confins du cosmos en neuf chapitres fascinants. À peine remis des merveilles de notre berceau terrestre, nous voilà emmenés sur la Lune. Compagne de nos nuits, c'est l'un des astres les plus remarquables du système solaire. Elle affecte notre vie quotidienne de toutes sortes de manières, plus surprenantes les unes que les autres. Il en est de même du Soleil, sans qui la vie sur Terre serait impossible, et qui est de loin le plus grand, et le plus chaud, des objets que nous connaissons tous bien. Des photographies splendides accompagnent la description de nos planètes voisines, au nom familier mais aux caractéristiques bien moins connues. Notre galaxie, la Voie lactée, contient un nombre incalculable d'étoiles et nous offre un stupéfiant spectacle nocturne. Les auteurs nous expliquent comment les étoiles naissent et comment elles meurent, quels périls elles font courir, notamment sous forme de trous noirs. La Voie lactée nous est aussi présentée dans le contexte des centaines de galaxies qui peuplent le ciel. Mais même cette immensité pâlit au regard des dernières idées sur le nombre infini d'univers qui pourraient bien exister. Cette invitation au voyage dans les étoiles se conclut sur les scénarios les plus vraisemblables du mystère des mystères : comment la vie est apparue dans l'Univers.

  • Décrit la quête rationnelle de l'origine, entreprise depuis 300 ans, et guide nos pas sur le chemin balisé par des générations d'astronomes et physiciens depuis Galilée jusqu'à Hawking. La grande vision qu'offre ce livre est le mariage entre physique des particules et cosmologie.

  • Popular science master John Gribbin takes us on a delightfully mind-bending tour through the 'big six' theories of quantum physics, from the Copenhagen interpretation to the pilot wave.

  • From the bestselling author of Science: A History comes the enthralling story of a revolution that shook the world. Seventeenth-century England was racked by civil war, plague and fire; a world ruled by superstition and ignorance. A series of meetings of 'natural philosophers' in Oxford and London saw the beginning of a new method of thinking based on proof and experiment. John Gribbin's gripping, colourful account of this unparalleled time of discovery explores the impact of the Royal Society, culminating with Isaac Newton's revolutionary description of the universe and Edmund Halley's prediction of the return of a comet in 1759. This compelling book shows the triumph not as the work of one isolated genius, but of a Fellowship.

  • Quantum theory is so shocking that Einstein could not bring himself to accept it. It is so important that it provides the fundamental underpinning of all modern sciences. Without it, we'd have no computers, no science of molecular biology, no understanding of DNA, no genetic engineering.In Search of Schrodinger's Cat tells the complete story of quantum mechanics, a truth stranger than any fiction. John Gribbin takes us step by step into an even more bizarre and fascinating place, requiring only that we approach it with an open mind. He introduces the scientists who developed quantum theory. He investigates the atom, radiation, time travel, the birth of the universe, super conductors and life itself. And in a world full of its own delights, mysteries and surprises, he searches for Schrodinger's Cat - a search for quantum reality - as he brings every reader to a clear understanding of the most important area of scientific study today - quantum physics.In Search of Schrodinger's Cat is a fascinating and delightful introduction to the strange world of the quantum - an essential element in understanding today's world.

  • Erwin Schrödinger was an Austrian physicist famous for his contribution to quantum physics. He won the Nobel Prize in 1933 and is best known for his thought experiment of a cat in a box, both alive and dead at the same time, which revealed the seemingly paradoxical nature of quantum mechanics. Schrödinger was working at one of the most fertile and creative moments in the whole history of science. By the time he started university in 1906, Einstein had already published his revolutionary papers on relativity. Now the baton of scientific progress was being passed to a new generation: Werner Heisenberg, Paul Dirac, Niels Bohr, and of course, Schrödinger himself. In this riveting biography John Gribbin takes us into the heart of the quantum revolution. He tells the story of Schrödinger's surprisingly colourful life (he arrived for a position at Oxford University with both his wife and mistress). And with his trademark accessible style and popular touch, he explains the fascinating world of quantum mechanics, which underpins all of modern science.

  • The quantum computer is no longer the stuff of science fiction. Pioneering physicists are on the brink of unlocking a new quantum universe which provides a better representation of reality than our everyday experiences and common sense ever could. The birth of quantum computers - which, like Schrödinger's famous 'dead and alive' cat, rely on entities like electrons, photons or atoms existing in two states at the same time - is set to turn the computing world on its head.In his fascinating study of this cutting-edge technology, John Gribbin updates his previous views on the nature of quantum reality, arguing for a universe of many parallel worlds where 'everything is real'. Looking back to Alan Turing's work on the Enigma machine and the first electronic computer, Gribbin explains how quantum theory developed to make quantum computers work in practice as well as in principle. He takes us beyond the arena of theoretical physics to explore their practical applications - from machines which learn through 'intuition' and trial and error to unhackable laptops and smartphones. And he investigates the potential for this extraordinary science to create a world where communication occurs faster than light and teleportation is possible.

  • Jim Lovelock is an iconic figure in British science, a prophet whose prophecies are coming true. This is his definitive authorised biography. Lovelock is best known as the 'father' of Gaia theory, which isnow established as the most useful way of understanding the dramatic changes happening to the environment of the Earth.But few people know about his early work as a chemist and inventor - work which included inventing the detectors used to search for life on Mars, and blowing the whistle on the depletion of ozone layer. In his personal life, he was a Quaker and conscientious objector in World War Two (later changing his mind in view of the evils of Nazism), supported his family for a time by selling his own blood, and gave up a salary and security to become an independent scientist based in an English village - from which all his best known work emerged.As he approaches his 90th birthday, looking forward to going into space, this book truly reveals an independent, original and inspiring life.

  • 'Gribbin takes us through the basics with his customary talent for accessibility and clarity' Sunday TimesThe world around us can be a complex, confusing place. Earthquakes happen without warning, stock markets fluctuate, weather forecasters seldom seem to get it right - even other people continue to baffle us. How do we make sense of it all?In fact, John Gribbin reveals, our seemingly random universe is actually built on simple laws of cause and effect that can explain why, for example, just one vehicle braking can cause a traffic jam; why wild storms result from a slight atmospheric change; even how we evolved from the most basic materials. Like a zen painting, a fractal image or the pattern on a butterfly's wings, simple elements form the bedrock of a sophisticated whole.Synthesizing chaos and complexity theory for the perplexed, Deep Simplicity brilliantly illuminates the harmony underlying our existence.

  • In this book, John Gribbin tells the story of the people who made science and the turbulent times they lived in. As well as famous figures such as Copernicus, Darwin and Einstein, there are also the obscure, the eccentric, even the mad. This diversecast includes, among others, Andreas Vesalius, landmark 16th-century anatomist and secret grave-robber; the flamboyant Galileo, accused of heresy for his ideas; the obsessive, competitive Newton, who wrote his rivals out of the history books; GregorMendel, the Moravian monk who founded modern genetics; and Louis Agassiz, so determined to prove the existence of ice ages that he marched his colleagues up a mountain to show them the evidence.

  • Does one planet really matter among the immensity of the Cosmos? John Gribbin is here to persuade us that it does. In this ground-breaking and provocative new book Gribbin argues that we owe our existence to the impact of a 'supercomet' with Venus 600 million years ago. But this is only part of the story, just one of the astronomical and geophysical reasons why the Earth is special. For the first time, he makes the link between the whole series of cosmic events that have affected the Earth and given rise to our intelligent civilization - a civilization, Gribbin argues, that is unique within our Milky Way Galaxy. Even if other Earths are common, and life itself may be common, the kind of intelligent, technological civilization that has emerged on Earth occurs only here. If humankind can survive the present environmental crises, the whole of the galaxy may become our home. And if not, our demise may be an event of literally universal significance.

    There are several hundred billion stars in our Milky Way Galaxy, yet out of all of these Earth is the only planet with intelligent life on it. Why? The author shows just what it is that makes our planet so special. He explores the biggest questions of all: why are we here, what does it mean to be alone in the universe - and do we have a future?

  • What are the boundaries of our universe? Can there be different physical laws from the ones we know? Are there in fact other universes? Do we really live in a multiverse? This book takes us on a journey, examining the most fundamental questions in science. It explores the frontiers of reality.

  • Navigating through the frontiers of scientific discovery, this work tells us what we really know about the history of the universe. It describes how the universe began; what the early universe looked like; how its structure developed; and looks to the future: is the history of the universe going to end with a Big Crunch or a Big Rip?
