• Savez-vous que vous voyagez à la vitesse de la lumière? Bien sûr, nous ne parlons pas ici d'un voyage dans l'espace en trois dimensions, mais dans la structure profonde de l'univers: l'espace-temps. Vous trouvez cela difficile à croire? Pourtant c'est bien ce que nous dit la fameuse équation d'Einstein: E=mc2!
    En talentueux passeurs de savoirs, Brian Cox et Jeff Forshaw nous révèlent dans ce livre les mystères de la théorie de  la relativité. Grâce à eux, même sans bagage mathématique, vous pourrez percer les secrets de l'équation la plus célèbre du monde!

  • Brian Cox et Jeff Forshaw révèlent dans cet ouvrage la signification profonde de la physique  quantique. Ils montrent pourquoi elle fournit une description de la Nature avec un immense pouvoir prédictif et explicatif, couvrant une vaste gamme de phénomènes, des puces de silicium aux fonctionnement des étoiles. L'histoire commence au tournant du XXe siècle, avec l'hypothèse de Max Planck  qui postule que le rayonnement lumineux dégagé par un corps chaud est constituée de petits paquets d'énergie qu'il nomme "quanta". Brian Cox et Jeff Forshaw explorent ensuite plus d'un siècle de découvertes et de questionnements, jusqu'au fameux boson de higgs, clé de voûte du modèle standard décrivant la matière à son niveau le plus élémentaire.

  • The Quantum Universe brings together two authors on a brilliantly ambitious mission to show that everyone can understand the deepest questions of science.

    But just what is quantum physics? How does it help us understand the world? Where does it leave Newton and Einstein? And why, above all, can we be sure that the theory is good?

    The bizarre behaviour of the atoms and energy that make up the universe has led to some very woolly pronouncements on the nature of all interconnectedness. Here, Brian Cox and Jeff Forshaw give us the real science, and reveal the profound theories that allow for concrete, yet astonishing, predictions about the world.

    This is our most up-to-date picture of reality.

  • We dare to imagine a time before the Big Bang, when the entire Universe was compressed into a space smaller than an atom. And now, as Brian Cox and Jeff Forshaw show, we can do more than imagine: we can understand. Over the centuries, the human urge to discover has unlocked an incredible amount of knowledge. What it reveals to us is breathtaking. Universal takes us on an epic journey of scientific exploration and, in doing so, reveals how we can all understand some of the most fundamental questions about our Earth, Sun, Solar System and the star-filled galaxies beyond. Some of these questions - How big is our solar system? How fast is space expanding? - can be answered from your back garden; the answers to others - How big is the Universe? What is it made of? - draw on the astonishing information now being gathered by teams of astronomers operating at the frontiers of the known universe.At the heart of all these questions - from the earliest attempts to quantify gravity, to our efforts to understand what dark matter is and what really happened at the birth of our universe - is the scientific process. Science reveals a deeper beauty, connects us to each other, to our world, and to our Universe; and, by understanding the groundbreaking work of others, reaches out into the unknown. What's more, as Universal shows us, if we dare to imagine, we can all do it.

  • The most accessible, entertaining, and enlightening explanation of the best-known physics equation in the world, as rendered by two of today’s leading scientists.Professor Brian Cox and Professor Jeff Forshaw go on a journey to the frontier of 21st century science to consider the real meaning behind the iconic sequence of symbols that make up Einstein’s most famous equation, E=mc2. Breaking down the symbols themselves, they pose a series of questions: What is energy? What is mass? What has the speed of light got to do with energy and mass? In answering these questions, they take us to the site of one of the largest scientific experiments ever conducted. Lying beneath the city of Geneva, straddling the Franco-Swiss boarder, is a 27 km particle accelerator, known as the Large Hadron Collider. Using this gigantic machine--which can recreate conditions in the early Universe fractions of a second after the Big Bang--Cox and Forshaw will describe the current theory behind the origin of mass.Alongside questions of energy and mass, they will consider the third, and perhaps, most intriguing element of the equation: 'c' - or the speed of light. Why is it that the speed of light is the exchange rate? Answering this question is at the heart of the investigation as the authors demonstrate how, in order to truly understand why E=mc2, we first must understand why we must move forward in time and not backwards and how objects in our 3-dimensional world actually move in 4-dimensional space-time. In other words, how the very fabric of our world is constructed. A collaboration between two of the youngest professors in the UK, Why Does E=mc2? promises to be one of the most exciting and accessible explanations of the theory of relativity in recent years.

  • E=mc2 est certainement la formule mathématique la plus connue au monde et pourtant peu savent ce qu'elle signifie exactement. Cet ouvrage explore la signification profonde de la fameuse équation d'Einstein et répond en termes simples aux questions qu'elle pose: qu'est-ce que l'énergie ? Qu'est-ce que la masse ? Qu'est-ce que la vitesse de la lumière a à voir avec elles ? Pour pénétrer les mystères de la matière, les auteurs nous entraîne au coeur du LHC, ce gigantesque acélérateur de particules situé près de Genève qui doit recréer les conditions de la naissance de l'univers. Au terme de leur enquête, vous comprendrez enfin pourquoi le monde est ce qu'il est !
