Robert Lawlor sets out the system that determines the dimension and the form of both man-made and natural structures, from Gothic cathedrals to flowers, from music to the human body. By also involving the reader in practical experiments, he leads with ease from simple principles to a grasp of the logarithmic spiral, the Golden Proportion, the squaring of the circle and other ubiquitous ratios and proportions.Art and Imagination: These large-format, gloriously-illustrated paperbacks cover Eastern and Western religion and philosophy, including myth and magic, alchemy and astrology. The distinguished authors bring a wealth of knowledge, visionary thinking and accessible writing to each intriguing subject.

    Students, researchers, historians, specialists — in short, everyone with an interest in mathematics — will find it engrossing and stimulating.Beginning with the ancient Near East, the author traces the ideas and techniques developed in Egypt, Babylonia, China, and Arabia, looking into such manuscripts as the Egyptian Papyrus Rhind, the Ten Classics of China, and the Siddhantas of India. He considers Greek and Roman developments from their beginnings in Ionian rationalism to the fall of Constantinople; covers medieval European ideas and Renaissance trends; analyzes 17th- and 18th-century contributions; and offers an illuminating exposition of 19th century concepts. Every important figure in mathematical history is dealt with — Euclid, Archimedes, Diophantus, Omar Khayyam, Boethius, Fermat, Pascal, Newton, Leibniz, Fourier, Gauss, Riemann, Cantor, and many others.For this latest edition, Dr. Struik has both revised and updated the existing text, and also added a new chapter on the mathematics of the first half of the 20th century. Concise coverage is given to set theory, the influence of relativity and quantum theory, tensor calculus, the Lebesgue integral, the calculus of variations, and other important ideas and concepts. The book concludes with the beginnings of the computer era and the seminal work of von Neumann, Turing, Wiener, and others."The author's ability as a first-class historian as well as an able mathematician has enabled him to produce a work which is unquestionably one of the best." — Nature Magazine.

    Would you believe that these five pieces can be reassembled in such a fashion so as to create two apples equal in shape and size to the original? Would you believe that you could make something as large as the sun by breaking a pea into a finite number of pieces and putting it back together again? Neither did Leonard Wapner, author of The Pea and the Sun, when he was first introduced to the Banach-Tarski paradox, which asserts exactly such a notion. Written in an engaging style, The Pea and the Sun catalogues the people, events, and mathematics that contributed to the discovery of Banach and Tarski's magical paradox. Wapner makes one of the most interesting problems of advanced mathematics accessible to the non-mathematician.

    But people want to know about a book that, they are told, defines Judaism. Everyman's Talmud is the right place to begin not only to learn about Judaism in general but to meet the substance of the Talmud in particular . . . In time to come, Cohen's book will find its companion-though I do not anticipate it will ever require a successor for what it accomplishes with elegance and intelligence: a systematic theology of the Talmud's Judaism.--From the Foreword by Jacob NeusnerLong regarded as the classic introduction to the teachings of the Talmud, this comprehensive and masterly distillation summarizes the wisdom of the rabbinic sages on the dominant themes of Judaism: the doctrine of God; God and the universe; the soul and its destiny; prophesy and revelation; physical life; moral life and social living; law, ethics, and jurisprudence; legends and folk traditions; the Messiah and the world to come.

    Now, for the first time since his classic Just and Unjust Wars was published almost three decades ago, this volume brings together his most provocative arguments about contemporary military conflicts and the ethical issues they raise. The essays in the book are divided into three sections. The first deals with issues such as humanitarian intervention, emergency ethics, and terrorism. The second consists of Walzer’s responses to particular wars, including the first Gulf War, Kosovo, Afghanistan, and Iraq. And the third presents an essay in which Walzer imagines a future in which war might play a less significant part in our lives. In his introduction, Walzer reveals how his thinking has changed over time. Written during a period of intense debate over the proper use of armed force, this book gets to the heart of difficult problems and argues persuasively for a moral perspective on war.

    But as Cemil Aydin explains in this provocative history, it is a misconception to think that the world s 1.5 billion Muslims constitute a single religio-political entity. How did this belief arise, and why is it so widespread? The Idea of the Muslim World searches for the intellectual origins of a mistaken notion and explains its enduring allure for non-Muslims and Muslims alike.Conceived as the antithesis of Western Christian civilization, the idea of the Muslim world emerged in the late nineteenth century, when European empires ruled the majority of Muslims. It was inflected from the start by theories of white supremacy, but Muslims had a hand in shaping the idea as well. Aydin reveals the role of Muslim intellectuals in envisioning and essentializing an idealized pan-Islamic society that refuted claims of Muslims racial and civilizational inferiority.After playing a key role in the politics of the Ottoman Caliphate, the idea of the Muslim world survived decolonization and the Cold War, and took on new force in the late twentieth century. Standing at the center of both Islamophobic and pan-Islamic ideologies, the idea of the Muslim world continues to hold the global imagination in a grip that will need to be loosened in order to begin a more fruitful discussion about politics in Muslim societies today.

    To believers, the Ark was the vessel holding the stone tablets of the Ten Commandments. The bible contains hundreds of references to the Ark's power to level mountains, destroy armies & lay waste to cities. The Ark itself, however, mysteriously disappears from recorded history sometime after the building of the Temple of Solomon. After ten years of searching thru archives in Europe & the Middle East, as well as braving the real-life dangers of a bloody civil war in Ethiopia, Hancock has succeeded where scores of others have failed. This intrepid journalist has tracked down the true story behind the legends--revealing where the Ark is today, how it got there & why it remains hidden. Part fascinating scholarship, part entertaining adventure yarn, tying together some of the most intriguing tales of all time--from the Knights Templar & Prester John to Parsival & the Holy Grail--this book will appeal to anyone fascinated by the revelation of hidden truths.

    They lived life to the fullest, loved unashamedly, listened to their heart’s desires, and created one of the most advanced, culturally sophisticated societies ever known. Is all that now dead and buried? Or only for the professors to mull over?One classics scholar, Dr. Stephen Bertman, answers this resoundingly in The Eight Pillars of Greek Wisdom. He shows how to bring passion and excellence to the center of your daily life, as the ancient Greeks intended them to be. The lessons they learned—that life is brief and fragile and time is too precious to waste; that we do not know who we are until we discover who we can be; that we cannot undertake our voyage through life alone; that there will be obstacles along the way, but the greatest obstacle is within—led them to develop what Bertman describes as eight guiding principles of wisdom: Humanism The Pursuit of Excellence The Practice of Moderation Self-Knowledge Rationalism Restless Curiosity The Love of Freedom Individualism These eight pillars are explored in the book. Each is illuminated through vivid examples drawn from the rich heritage of classical history and mythology, including tales of gods and goddess, heroes and heroines, adventure and exploration, and self-discovery and personal triumph.

    “Europe,” he writes, “is the place where Goethe’s garden almost borders on Buchenwald, where the house of Corneille abuts on the market-place in which Joan of Arc was hideously done to death.” It is, in other words, a continent rich with contradiction, whose many tensions—cultural, social, political, economic, and religious—have for centuries conspired to pull it apart, even as it has become more and more unified. But what lies ahead for a continent whose borders are growing and economic might is strengthening, even as its cultural identity recedes? A continent where, in Steiner’s words, “young Englishmen choose to rank David Beckham high above Shakespeare and Darwin in their list of national treasures”? This is the trajectory that Steiner explores so brilliantly in The Idea of Europe.

    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.

     The impact of Christianity on world civilization is almost incalculable, and in exploring this rich heritage, nineteen leading scholars range from the earliest origins to the present day to examine virtually every aspect of the faith. They discuss the apostle Peter and Roman Emperor Constantine, describe the role of Charlemagne in the expansion of the religion, and assess medieval scholasticism and the influence of Thomas Aquinas. The profound changes that occurred during both the Reformation and the Enlightenment are fully treated in chapters that offer revealing portraits of such key figures as Erasmus, Luther, Calvin, Wesley, and Rousseau. Fully one third of the book covers Christianity since 1800--with special studies of the faith as practiced in Britain and Europe, North and South America, Africa, India, and the Far East--offering a compelling continuous narrative filled with insight into the enormously diverse Christian world. In the final chapters, the authors consider questions of contemporary Christian theology, conscience and belief, and explore new concepts of Christian community. Over 350 beautiful illustrations--including 32 full color plates--grace the text, ranging from mosaics, paintings and sculptures, to architecture and modern art. There are also ten maps, a chronology of important events, and an annotated guide to further reading. Throughout, the book reflects the changing world in which Christians have found themselves, and the many ways in which, individually and through the institutions of the church, they in turn have influenced history. Comprehensive, vividly narrated, and exquisitely produced, this magnificent book captures the richness and vitality of Christian thought and culture throughout the ages.
