Une brève histoire du temps: Les grandes théories du cosmos : du Big Bang aux trous noirs
Voici le premier livre que Stephen Hawking a écrit pour le grand public. Il y expose, dans un langage accessible à tous, les plus récentes découvertes des astrophysiciens. Retraçant les grandes théories du cosmos depuis Galilée jusqu'à Einstein, racontant les ultimes découvertes en cosmologie, expliquant la nature des trous noirs, il propose ensuite de relever le plus grand défi de la science moderne : la recherche d'une théorie permettant de concilier la relativité générale et la mécanique quantique.Stephen Hawking a lutté pendant plus de quarante ans contre une très grave maladie neurodégénérative. Malgré ce handicap, il a consacré sa vie à tenter de percer les secrets de l'Univers et à nous faire partager ses découvertes. Un livre fascinant devenu un best-seller mondial.
Shadow Of Night
Picking up from A Discovery of Witches’ cliffhanger ending, Shadow of Night takes Diana and Matthew on a trip through time to Elizabethan London, where they are plunged into a world of spies, magic, and a coterie of Matthew’s old friends, the School of Night. As the search for Ashmole 782 deepens and Diana seeks out a witch to tutor her in magic, the net of Matthew’s past tightens around them, and they embark on a very different—and vastly more dangerous—journey.
Discovery of Witches
It begins with absence and desire. It begins with blood and fear. It begins with a discovery of witches. When historian Diana Bishop opens an alchemical manuscript in the Bodleian Library, it's an unwelcome intrusion of magic into her carefully ordered life. Though Diana is a witch of impeccable lineage, the violent death of her parents while she was still a child convinced her that human fear is more potent than any witchcraft. Now Diana has unwittingly exposed herself to a world she's kept at bay for years: one of powerful witches, creative, destructive daemons and long-lived vampires. Sensing the significance of Diana's discovery, the creatures gather in Oxford, among them the enigmatic Matthew Clairmont, a vampire genticist. Diana is inexplicably drawn to Matthew and, in a shadowy world of half-truths and old enmities, ties herself to him without fully understanding the ancient line they are crossing. As they begin to unlock the secrets of the manuscript and their feelings for each
Harry Potter Et Le Prince De Sang-mêlé (Folio Junior)
Dans un monde de plus en plus inquiétant, Harry se prépare à retrouver Ron et Hermione. Bientôt, ce sera la rentrée à Poudlard, avec les autres étudiants de sixième année.

Discours sur l’origine de l’univers
D'où vient l'univers ? Et d'où vient qu'il y a un univers ? Irrépressiblement, ces questions se posent à nous. Et dès qu'un discours prétend nous éclairer, nous tendons l'oreille, avides d'entendre l'écho du tout premier signal : les accélérateurs de particules vont bientôt nous révéler l'origine de l'univers en produisant des "big bang sousterre" : les données recueillies par le satellite Planck nous dévoiler le "visage de Dieu" : certains disent même qu'en vertu de la loi de la gravitation l'univers a pu se créer de lui-même, à partir de rien... Le grand dévoilement ne serait donc devenu qu'une affaire d'ultimes petits pas ? Rien n'est moins sûr... Car de quoi parle la physique quand elle parle d'"origine" ? Qu'est-ce que les théories actuelles sont réellement en mesure de nous révéler ? À bien les examiner, les perspectives que nous offre la cosmologie contemporaine sont plus vertigineuses encore que tout ce que nous avons imaginé : l'univers a-t-il jamais commencé ?From the Back CoverD'où vient l'univers?

The Other Pandemic
Pulitzer Prize-winning investigative journalist James Ball takes us into the depths of the internet to trace the origins and rapid ascent of QAnon, the movement that mutated from a niche online conspiracy theory into the world's first digital pandemic.*A Financial Times Book to Read in 2023*Imagine a deadly pathogen that, once created, could infect any person in any part of the globe within seconds. No need to wait for travellers, trains, or air traffic to spread it, all you need is an internet connection. In this gripping investigation, Pulitzer Prize winner James Ball decodes the cryptic language of the online right and with a surgeon's precision tracks the spread of QAnon, the world's first digital pandemic.QAnon began as an internet community dedicated to supporting President Trump and intent on outing a global cabal of human traffickers. A short, cryptic message posted by an anonymous user to a niche internet forum in 2017 was the spark that ignited a global movement. What started as a macabre game of virtual make-believe quickly spiralled into the spread of virulently hateful, dangerous messaging – which turned into tragic, violent actions.Incoherent, chaotic, free from QAnon is a one-size-fits all cult conspiracy. From a standoff at the Hoover Dam, to the storming of the U.S. Capitol on 6 January 2021, to protesting COVID-19 lockdowns, this digital pandemic has spread globally and shows no signs of stopping. In The Other Pandemic Ball takes us into the niche pathways through which these digital pathogens spread, mutate and infect people all across the globe – but he also argues that the prognosis doesn't have to be dire. He shows us that it is possible to treat and cure this virus in order to build up our digital immune systems, and be better prepared to survive the next wave.
In Search Of Schrodinger’s Cat
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 nuclear power or nuclear weapons, no TV, 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 ever 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, superconductors 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.
