It deals with one powerful obsession that preoccupied Escher: what he called "the regular division of the plane," the puzzlelike interlocking of birds, fish, lizards, and other natural forms in continuous patterns. Schattschneider asks, "How did he do it?" She answers the question by analyzing Escher's notebooks." Visions of Symmetry includes many of Escher's masterworks, as well as hundreds of lesser-known examples of his work. This new edition also features a foreward and an illustrated epilogue that reveals new information about Escher's inspiration and shows how his ideas of symmetry have influenced mathematicians, computer scientists, and contemporary artists.

    His skill as a reviewer is particularly notable: never content merely to assess the ideas of a writer and the theses of a book, Eagleton, in his inimitable and often wickedly funny style, always paints a vivid theoretical and political fresco as the background to his engagement with the texts.In this collection of more than a decade of such bracing criticism, Eagleton comes face to face with Stanley Fish, Gayatri Spivak, Slavoj Žižek, Edward Said, and even David Beckham. All are subjected to his pugnacious wit, scathing critical pen, and brilliant literary investigations.

    Now he brings his considerable talents to the history of one of math's most enduring puzzles: the seemingly paradoxical nature of infinity.Is infinity a valid mathematical property or a meaningless abstraction? The nineteenth-century mathematical genius Georg Cantor's answer to this question not only surprised him but also shook the very foundations upon which math had been built. Cantor's counterintuitive discovery of a progression of larger and larger infinities created controversy in his time and may have hastened his mental breakdown, but it also helped lead to the development of set theory, analytic philosophy, and even computer technology.Smart, challenging, and thoroughly rewarding, Wallace's tour de force brings immediate and high-profile recognition to the bizarre and fascinating world of higher mathematics.

    In these lectures, Heidegger reviews and makes critical appropriations of the hermeneutic tradition from Plato, Aristotle, and Augustine to Schleiermacher and Dilthey in order to reformulate the question of being on the basis of facticity and the everyday world. Specific themes deal with the history of ontology, the development of phenomenology and its relation to Hegelian dialectic, traditional theological and philosophical concepts of man, the present situation of philosophy, and the influences of Aristotle, Luther, Kierkegaard, and Husserl on Heidegger's own thinking. Students of Heidegger will find initial breakthroughs in his unique elaboration of the meaning of human existence and the "question of being, " which received mature expression in Being and Time.

    Ten dimensions? Most of us have barely gotten used to the idea that there are four.Using simple geometry and an easygoing writing style, author Rob Bryanton starts with the lower dimensions that we are all familiar with, then uses those concepts to build one layer upon another, ultimately arriving at a way of imagining the tenth dimension.Part scientific exploration, part philosophy, this unique book touches upon such diverse topics as dark matter, Feynman's "sum over paths", the quantum observer, and the soul. It is aimed at anyone interested in leading-edge theories about cosmology and the nature of reality, but it is not about mainstream physics. Rather, Imagining the Tenth Dimension is a mind-expanding exercise that could change the way you view this incredible universe in which we live.

    Bob Smith, founded Alcoholics Anonymous in 1935, his hope was that AA would become a safe haven for those who suffered from this disease. Thirty years after his death, AA continues to help millions of alcoholics recover from what had been commonly regarded as a hopeless addiction. Still, while Wilson was a visionary for millions, he was no saint. After cofounding Alcoholics Anonymous, he stayed sober for over thirty-five years, helping countless thousands rebuild their lives. But at the same time, Wilson suffered form debilitating bouts of clinical depression, was a womanizer, and experimented with LSD.Francis Hartigan, the former secretary and confidant to Wilson's wife, Lois, has exhaustively researched his subject, writing with a complete insider's knowledge. Drawing on extensive interviews with Lois Wilson and scores of early members of AA, he fully explores Wilson's organizational genius, his devotion to the cause, and almost martyr-like selflessness. That Wilson, like all of us, had to struggle with his own personal demons makes this biography all the more moving and inspirational. Hartigan reveals the story of Wilson's life to be as humorous, horrific, and powerful as any of the AA vignettes told daily around the world.

    For centuries, the power of zero savored of the demonic; once harnessed, it became the most important tool in mathematics. Zero follows this number from its birth as an Eastern philosophical concept to its struggle for acceptance in Europe and its apotheosis as the mystery of the black hole. Today, zero lies at the heart of one of the biggest scientific controversies of all time, the quest for the theory of everything. Elegant, witty, and enlightening, Zero is a compelling look at the strangest number in the universe and one of the greatest paradoxes of human thought.

    In the four main sections of the book, Stein tells the stories of the mathematical thinkers who discerned some of the most fundamental aspects of our universe. From their successes and failures, delusions, and even duels, the trajectories of their innovations—and their impact on society—are traced in this fascinating narrative. Quantum mechanics, space-time, chaos theory and the workings of complex systems, and the impossibility of a "perfect" democracy are all here. Stein's book is both mind-bending and practical, as he explains the best way for a salesman to plan a trip, examines why any thought you could have is imbedded in the number π , and—perhaps most importantly—answers one of the modern world's toughest questions: why the garage can never get your car repaired on time.Friendly, entertaining, and fun, How Math Explains the World is the first book by one of California's most popular math teachers, a veteran of both "math for poets" and Princeton's Institute for Advanced Studies. And it's perfect for any reader wanting to know how math makes both science and the world tick.

    It now has 600,000 to a million page hits daily. Every now and then, Munroe would get emails asking him to arbitrate a science debate. 'My friend and I were arguing about what would happen if a bullet got struck by lightning, and we agreed that you should resolve it . . . ' He liked these questions so much that he started up What If. If your cells suddenly lost the power to divide, how long would you survive? How dangerous is it, really, to be in a swimming pool in a thunderstorm? If we hooked turbines to people exercising in gyms, how much power could we produce? What if everyone only had one soulmate?When (if ever) did the sun go down on the British empire? How fast can you hit a speed bump while driving and live?What would happen if the moon went away?In pursuit of answers, Munroe runs computer simulations, pores over stacks of declassified military research memos, solves differential equations, and consults with nuclear reactor operators. His responses are masterpieces of clarity and hilarity, studded with memorable cartoons and infographics. They often predict the complete annihilation of humankind, or at least a really big explosion. Far more than a book for geeks, WHAT IF: Serious Scientific Answers to Absurd Hypothetical Questions explains the laws of science in operation in a way that every intelligent reader will enjoy and feel much the smarter for having read.
