Bücher von Ian Stewart

The fourth book in the Science of Discworld series, and this time around dealing with THE REALLY BIG QUESTIONS, Terry Pratchett s brilliant new Discworld story Judgement Day is annotated with very big footnotes (the interleaving chapters) by mathematician Ian Stewart and biologist Jack Cohen, to bring you a mind-mangling combination of fiction, cutting-edge science and philosophy.Marjorie Daw is a librarian, and takes her job and indeed the truth of words very seriously. She doesn t know it, but her world and ours Roundworld is in big trouble. On Discworld, a colossal row is brewing The Wizards of Unseen University feel responsible for Roundworld (as one would for a pet gerbil). After all, they brought it into existence by bungling an experiment in Quantum ThaumoDynamics. But legal action is being brought against them by Omnians, who say that the Wizards god-like actions make a mockery of their noble religion.As the finest legal brains in Discworld (a zombie and a priest) gird their loins to do battle and when the Great Big Thing in the High Energy Magic Laboratory is switched on Marjorie Daw finds herself thrown across the multiverse and right in the middle of the whole explosive affair. As God, the Universe and, frankly, Everything Else is investigated by the trio, you can expect world-bearing elephants, quantum gravity in the Escher-verse, evolutionary design, eternal inflation, dark matter, disbelief systems and an in-depth study of how to invent a better mousetrap.

Examines seventeen groundbreaking equations that have altered the course of human history. This book explores how Pythagoras' Theorem led to GPS and SatNav; how logarithms are applied in architecture; why imaginary numbers were important in the development of the digital camera, and what is really going on with Schrodinger's cat.

Wozu brauchen wir im täglichen Leben Mathematik ? Warum es ganz und gar nicht «sinnlos» ist (wie viele zu Schulzeiten denken mögen), sich mit Mathematik zu beschäftigen, erklärt der renommierte Professor und Bestsellerautor Ian Stewart in seinem neuen faktenreichen und anschaulichen Buch. Tatsächlich würde unsere moderne Welt ohne Mathematik auseinanderfallen, denn sie begegnet uns überall: Wenn wir ein Selfie machen, einen Film gucken, ChatGPT nutzen oder eine Niere spenden , aber auch wenn im Supermarkt Regale aufgefüllt, ein Fall vor Gericht verhandelt wird oder eine Partei aus politischen Minderheiten Mehrheiten macht. Ian Stewart gewährt uns einen Blick hinter die Kulissen des Alltags und zeigt die Relevanz der Mathematik auch dort, wo wir sie nicht vermuten.

Don't poke your nose down a wormhole - you never know what you might find.Two universes joined by a wormhole pair that forms a 'loophole', with an icemoon orbiting through the loophole, shared between two different planetary systems in the two universes.A civilisation with uploaded minds in virtual reality served by artificial humans.A ravening Horde of replicating machines that kill stars.Real humans from a decrepit system of colony worlds.A race of hyperintelligent but somewhat vague aliens.Who will close the loophole... who will exploit it?Cover design: David A. Hardy

This highly interdisciplinary book, covering more than six fields, from philosophy and sciences all the way up to the humanities and with contributions from eminent authors, addresses the interplay between content and context, reductionism and holism and their meeting point: the notion of emergence. Much of today's science is reductionist (bottom-up); in other words, behaviour on one level is explained by reducing it to components on a lower level. Chemistry is reduced to atoms, ecosystems are explained in terms of DNA and proteins, etc. This approach fails quickly since we can't cannot extrapolate to the properties of atoms solely from Schrodinger's equation, nor figure out protein folding from an amino acid sequence or obtain the phenotype of an organism from its genotype. An alternative approach to this is holism (top-down). Consider an ecosystem or an organism as a whole: seek patterns on the same scale. Model a galaxy not as 400 billion-point masses (stars) but as an object in its own right with its own properties (spiral, elliptic). Or a hurricane as a structured form of moist air and water vapour. Reductionism is largely about content, whereas holistic models are more attuned to context. Reductionism (content) and holism (context) are not opposing philosophies - in fact, they work best in tandem. Join us on a journey to understand the multifaceted dialectic concerning this duo and how they shape the foundations of sciences and humanities, our thoughts and, the very nature of reality itself.

A workshop on Singularities, Bifuraction and Dynamics was held at Warwick in July 1989, as part of a year-long symposium on Singularity Theory and its applications. The proceedings fall into two halves: Volume I mainly on connections with algebraic geometry and volume II on connections with dynamical systems theory, bifurcation theory and applications in the sciences. The papers are original research, stimulated by the symposium and workshop: All have been refereed and none will appear elsewhere. The main topic of volume II is new methods for the study of bifurcations in nonlinear dynamical systems, and applications of these.

Sie kamen aus allen Schichten und lebten in aller Herren Länder; sie waren Exzentriker wie Isaac Newton, Außenseiter wie Alan Turing oder gehörten zum Establishment wie Pierre de Fermat. Sie starben früh wie George Boole oder wurden steinalt wie Benoit Mandelbrot, waren Wunderknaben wie Karl Friedrich Gauss oder mussten sich mit Vorurteilen herumschlagen wie Emmy Noether. Fünfundzwanzig Biografien von bahnbrechenden Größen der Mathematik versammelt Ian Stewart in diesem Band. 25 abgeschlossene Lebensgeschichten über 25 Jahrhunderte, die davon erzählen, wie und unter welchen Lebens- und Gesellschaftsumständen die ganz Großen zu ihren historischen Entdeckungen kamen. Wobei Mathematiker dieses Kalibers eben nicht entdecken, was schon da wäre, sondern das Neuland selbst erschaffen, das sie und wir anderen dann betreten. Drei Frauen sind darunter (Augusta Ada King, Sofia Kowalewskaja und Emmy Noether), denen Stewart besonderen Respekt zollt, weil sie nicht nur mit kniffligen Berechnungen, sondern auch mit rigiden gesellschaftlichen Hindernissen und Vorurteilen zu kämpfen hatten.Gibt es das Mathe-Gen? - Nein, sagt Stewart. Aber bei vielen gibt es durchaus einen hochentwickelten Hirnsektor für das Visuelle. Tatsächlich denken große Mathematiker mehr in Bildern als in Formeln; sie sind konzentrationsstark, haben ein gutes Gedächtnis, große Ausdauer und folgen gern ihrer Intuition. Die meisten jedenfalls. Allen gemeinsam aber ist eine Besessenheit von Mathematik, die sie über die Zeiten und Länder, über Herkunft und Status hinweg zu herausragenden Wissenschaftlern machte.

Warum haben Ihre Freunde scheinbar mehr Freunde als Sie selbst? Wie kommt der Leopard zu seinen Punkten? Wer lüftet das Geheimnis der 37? Warum sind Hexakosioihexekontahexaphobiker schlicht im Irrtum? Und wie löst man das 15er-Puzzle? Hier kommt Ian Stewarts dritte und letzte Sammlung bunter mathematischer Preziosen: Fakten, Anekdoten, Spiele, Knobeleien, Kuriosa, Grundlagenwissen und überraschende Neuigkeiten. Schmankerl für Krimiliebhaber: Conan-Doyle-Fan Stewart streut in seine rund 150 Kabinettstückchen immer wieder mathematische Detektivgeschichten ein, deren Helden ein gewisser Hemlock Soames und sein Sidekick Dr. Whatsup sind, wohnhaft in der Bakerstreet 222B. In den dramatischen Schlusskapiteln kommt es in der Schweiz zu einer letzten, tödlichen Konfrontation mit Soames' Erzfeind, dem teuflischen Professor Mogiarty... Die beiden ersten Bände, «Professor Stewarts Mathematisches Sammelsurium» sowie «Professor Stewarts Mathematische Schätze» haben Ian Stewart auch in Deutschland zum Lieblingsautor vieler Mathematik-Fans werden lassen. Dieser abschließende Band der Sammelsurium-Trilogien bietet wieder kurzweiliges mathematisches Infotainment, das kaum ein Autor so gut beherrscht wie Ian Stewart.

Enter the magical maze of mathematics and explore the surprising passageways of a fantastical world where logic and imagination converge. For mathematics is a maze-a maze in your head-a maze of ideas, a maze of logic. And that maze in your mind is a powerful tool for understanding an even bigger maze-the one of cause and effect that we call "e;the universe."e; That is its special kind of magic. Real magic. Strange magic. Infinitely fascinating magic. Acclaimed author Ian Stewart leads you swiftly and humorously through the junctions, byways, and secret passages of the magical maze to reveal its beauty, surprise, and power. Along the way, he reveals the infinite possibilities that arise from what he calls "e;the two-way trade between the natural world and the human mind."e; If you've always loved mathematics, you will find endless delights in the twists and turns of The Magical Maze. If you've always hated mathematics, a trip through this marvelous book will do much to change your mind.

It is only in recent times that infinite-dimensional Lie algebras have been the subject of other than sporadic study, with perhaps two exceptions: Cartan's simple algebras of infinite type, and free algebras.

Many of us already have at least a passing acquaintance with procedural languages such as BASIC or Pascal, but may not have met a functional language like Lisp before.

With over 25,000 copies sold since its first edition, this book provides an unrivalled introduction to the core concepts and basic techniques of transactional analysis (TA).

Bifurcation theory studies how the structure of solutions to equations changes as parameters are varied. Four broad topics are covered: group theory and steady-state bifurcation, equicariant singularity theory, Hopf bifurcation with symmetry, and mode interactions.

An eminent teacher and writer explores an idea both simple and complex, both multidisciplinary and unifying-the story of symmetry

The framework of 'symmetry' provides an important route between the abstract theory and experimental observations. From the reviews:"[The] rich collection of examples makes the book...extremely useful for motivation and for spreading the ideas to a large Community."--MATHEMATICAL REVIEWS

Students often find the subject of complex analysis very difficult. An opening chapter provides a brief history of complex analysis which sets it in context and provides motivation.

Offers 30 practical suggestions to help practising counsellors develop and enhance their Transactional Analysis (TA) counselling skills. After an introductory section that summarizes the uses of TA theory and technique, this book covers crucial aspects of best practice in TA.

Part of the "Key Figures in Psychotherapy" series, this text chronicles the life, contributions and influence of Eric Berne, founder of Transactional Analysis counselling.
