Ian Stewart

  • Dans ce livre, Ian Stewart retrace les efforts de la pensée humaine pour faire des prévisions, à l'aide des mathématiques,  sur tout ce qui est incertain. Météorologie ou économie, mécanique quantique, justice, mécanisme cérébral d'une prise de décision, hasard ou nécessité génétique... Stewart explore les nombreuses applications des probabilités et nous fait comprendre que, malgré tous nos efforts, une probabilité raisonnable reste la seule certitude!

  • Leur pouvoir caché est immense Elles révèlent les secrets les plus intimes de l'univers Apprenez à apprivoiser les équations et à en faire vos complices.

    Vous qui avez peur des équations, et vous qui croyez déjà les connaître, ne passez pas votre chem

  • La biologie a connu cinq révolutions : le microscope, la classification de Linné, la théorie de l'évolution, les découvertes du gène et de la structure de l'ADN. Une sixième révolution est en marche : on la doit aux mathématiques. Grâce à elles, la biologie n'a jamais été aussi près d'élucider les mystères du vivant.Avec un enthousiasme communicatif, Ian Stewart décrit les passerelles qui existent entre la théorie des graphes et la classification des êtres vivants, la géométrie en dimension quatre et la forme des virus, la théorie des jeux et les stratégies de reproduction...Vous découvrirez le lien entre les lapins, un célèbre mathématicien italien et les pétales de fleur, et comprendrez enfin pourquoi la queue d'un animal tacheté peut être zébrée alors que celle d'un animal zébré ne peut en aucun cas être tachetée... Étonnant, non ?

  • Comment transformer un cornet de glace en cube ? Quelle est la forme d'une larme ? Ian Stewart propose une nouvelle sélection de 20 explorations mathématiques, du voyage dans le temps au comportement bizarre d'objets familiers...  Nous y découvrons entre autres la cadence mathématiques d'une marche de quadrupèdes, la relation entre nombres premiers et sauts de kangourous et, bien évidemment, la meilleure façon de se faire des noeuds au cerveau.

  • School maths is not the interesting part. The real fun is elsewhere. Like a magpie, Ian Stewart has collected the most enlightening, entertaining and vexing 'curiosities' of maths over the years...Now, the private collection is displayed in his cabinet.



    There are some hidden gems of logic, geometry and probability - like how to extract a cherry from a cocktail glass (harder than you think), a pop up dodecahedron, the real reason why you can't divide anything by zero and some tips for making money by proving the obvious. Scattered among these are keys to unlocking the mysteries of Fermat's last theorem, the Poincaré Conjecture, chaos theory, and the P/NP problem for which a million dollar prize is on offer. There are beguiling secrets about familiar names like Pythagoras or prime numbers, as well as anecdotes about great mathematicians. Pull out the drawers of the Professor's cabinet and who knows what could happen...

  • Since the dramatic discovery of the mathematical concept of chaos in 1989, the controversy of its contents has settled down. This revised edition of Does God Play Dice? takes a fresh look at its achievements and potential. With a new preface and three completely new chapters, it includes the latest practical applications of chaos theory, such as developing intelligent heart pacemakers. All this provides a fascinating new answer to Einstien's question which provided the title of this book.

  • Like its wildly popular predecessors Cabinet of Mathematical Curiosities and Hoard of Mathematical Treasures, Professor Stewart's brand-new book is a miscellany of over 150 mathematical curios and conundrums, packed with trademark humour and numerous illustrations.



    In addition to the fascinating formulae and thrilling theorems familiar to Professor Stewart's fans, the Casebook follows the adventures of the not-so-great detective Hemlock Soames and his sidekick Dr John Watsup (immortalised in the phrase 'Watsup, Doc?'). By a remarkable coincidence they live at 222B Baker Street, just across the road from their more illustrious neighbour who, for reasons known only to Dr Watsup, is never mentioned by name. A typical item is 'The Case of the Face-Down Aces', a mathematical magic trick of quite devilish cunning...



    Ranging from one-liners to four-page investigations from the frontiers of mathematical research, the Casebook reveals Professor Stewart at his challenging and entertaining best.

  • Anglais Calculating the Cosmos

    Ian Stewart

    Ian Stewart's up-to-the-minute guide to the cosmos moves from the formation of the Earth and its Moon to the planets and asteroids of the solar system and from there out into the galaxy and the universe. He describes the architecture of space and time, dark matter and dark energy, how galaxies form, why stars implode, how everything began, and how it will end. He considers parallel universes, what forms extra-terrestrial life might take, and the likelihood of Earth being hit by an asteroid. Mathematics, Professor Stewart shows, has been the driving force in astronomy and cosmology since the ancient Babylonians. He describes how Kepler's work on planetary orbits led Newton to formulate his theory of gravity, and how two centuries later irregularities in the motion of Mars inspired Einstein's theory of General Relativity. In crystal-clear terms he explains the fundamentals of gravity, spacetime, relativity and quantum theory, and shows how they all relate to each other. Eighty years ago the discovery that the universe is expanding led to the Big Bang theory of its origins. This in turn led cosmologists to posit features such as dark matter and dark energy. But does dark matter exist? Could another scientific revolution be on the way to challenge current scientific orthodoxy? These are among the questions Ian Stewart raises in his quest through the realms of astronomy and cosmology.

  • Anglais Nature's Numbers

    Ian Stewart

    "It appears to us that the universe is structured in a deeply mathematical way. Falling bodies fall with predictable accelerations. Eclipses can be accurately forecast centuries in advance. Nuclear power plants generate electricity according to well-known formulas. But those examples are the tip of the iceberg. In Nature's Numbers, Ian Stewart presents many more, each charming in its own way.. Stewart admirably captures compelling and accessible mathematical ideas along with the pleasure of thinking of them. He writes with clarity and precision. Those who enjoy this sort of thing will love this book."--Los Angeles Times

  • Anglais Flatterland

    Ian Stewart

    First there was Edwin A. Abbott's remarkable Flatland, published in 1884, and one of the all-time classics of popular mathematics. Now, from mathematician and accomplished science writer Ian Stewart, comes what Nature calls "a superb sequel." Through larger-than-life characters and an inspired story line, Flatterland explores our present understanding of the shape and origins of the universe, the nature of space, time, and matter, as well as modern geometries and their applications. The journey begins when our heroine, Victoria Line, comes upon her great-great-grandfather A. Square's diary, hidden in the attic. The writings help her to contact the Space Hopper, who tempts her away from her home and family in Flatland and becomes her guide and mentor through ten dimensions. In the tradition of Alice in Wonderland and The Phantom Toll Booth, this magnificent investigation into the nature of reality is destined to become a modern classic.

  • Anglais The Annotated Flatland

    Ian Stewart

    Flatland is a unique, delightful satire that has charmed readers for over a century. Published in 1884 by the English clergyman and headmaster Edwin A. Abbott, it is the fanciful tale of A. Square, a two-dimensional being who is whisked away by a mysterious visitor to The Land of Three Dimensions, an experience that forever alters his worldview.Like the original, Ian Stewart's commentary takes readers on a strange and wonderful journey. With clarity and wit, Stewart illuminates Abbott's numerous Victorian references and touches on such diverse topics as ancient Babylon, Karl Marx, Mary Shelley's Frankenstein, Mt. Everest, H.G. Wells, and phrenology. The Annotated Flatland makes fascinating connections between Flatland and Abbott's era, resulting in a classic to rival Abbott's own, and a book that will inspire and delight curious readers for generations to come.

  • Derrière les murs de l´Université de l´Invisible, une expérience périlleuse aboutit accidentellement à la création d´un univers en réduction, un univers absurde fondé sur des règles logiques, un univers où la magie n´a pas cours, où la matière tend à s´agglomérer en sphères pour constituer des étoiles et des planètes, où la vie naissante suit le cours de l´évolution vers l´émergence de l´intelligence, bref un univers insensé : un Globe-monde !
    Notre univers. Notre planète, la Terre.
    Et les mages du Disque-monde, incrédules, en prennent connaissance dans un déroulé accéléré de son histoire.
    Ponctués par le récit de Terry Pratchett, les chapitres de Ian Stewart et Jack Cohen proposent un parcours argumenté de nos connaissances scientifiques, de la naissance de l´univers à la nature de l´intelligence en passant par l´avènement de la vie et l´« affaire » des dinosaures. Avec humour, finesse et légèreté, impertinence souvent, mais sans esquiver les pierres d´achoppement, ils nous conduisent à travers les questions les plus délicates vers la recherche d´une philosophie de la science qui éclaire le siècle nouveau.
    De la vulgarisation scientifique sérieuse et rigolote !

  • Qui obtiendra la garde du Globe-monde (le nôtre) ? Produit d´un tripatouillage magique à l´Université de l´Invisible, il repose présentement sur une étagère de l´estimable institution.

    Et voici que l´Église des Omniens des derniers jours en revendique la propriété. N´a-t-elle pas toujours affirmé que le monde était sphérique ? Et le Globe n´en apporte-t-il pas la preuve irréfutable ? Le tribunal présidé par le seigneur Vétérini tranchera.

    Malencontreusement aspirée sur le Disque-monde, l´énergique bibliothécaire Marjorie Daw en sera témoin, et c´est l´avenir de son univers (le nôtre) qui se jouera devant ses yeux.

    Parallèlement, le mathématicien Ian Stewart et le biologiste Jack Cohen examinent l´évolution de la pensée scientifique, sans cesse en butte aux dénis que lui oppose jusqu´à nos jours la pensée magique et religieuse.

    Cerise sur le gâteau, on croisera au tournant la célèbre équation de Schrödinger, celle-là même qui stipule qu´un chat peut être à la fois vivant et mort.

  • Vous le savez desormais, notre univers est le produit fortuit d'une expérience concoctée par les mages du Disque-monde.
    Bizarre, ce "Globe-monde" : il obéit à des règles de causalité et la magie n'y a pas cours. Mais un jour, apparaît un primate qui croit au pouvoir des histoires. L'éveil de son regard imprègne le monde de motivations, de désirs et d'aspirations. De narrativium. Un terrain d'invasion rêvé pour les elfes du Disque-monde...
    Dans ce deuxième livre, Terry Pratchett, Jack Cohen et Ian Stewart alternent à nouveau la vulgarisation scientifique et les tribulations des mages pôur aborder une question qui nous touche de près : l'évolution humaine.

    Qu'est ce que l'esprit humain exactement? Comment a-t-il pu naître de la rigidité des lois physiques? Qu'est ce qui nous distingue du règne animal?

    Un voyage étiourdissant et raisonné à travers la philosophie, la religion et la pensée scientifique. Une ode à l'esprit critique solidement documentée. Un livre utile en ces temps d'inventaire de nos valeurs. Et marrant ce qui ne gâte rien.
