Harmony is central. There are two key aspects to the visual structure of Islamic design, calligraphy using Arabic script-one of the world's great calligraphic traditions-and abstract ornamentation using a varied but remarkably integrated visual language. This art of pure ornament revolves around two central themes; crystalline geometric patterns, the harmonic and symmetrical subdivision of the plane giving rise to intricately interwoven designs that speak of infinity and the omnipresent center; and idealized plant form, spiraling tendrils, leaves, buds and flowers embodying organic life and rhythm.1.

    Itwas a time of exploration and conquest, but it ended in a retrenchment so complete that less than a century later, it was a crime to go to sea in a multimasted ship. In When China Ruled the Seas, Louise Levathes takes a fascinating and unprecedented look at this dynamic period in China's enigmatichistory, focusing on China's rise as a naval power that literally could have ruled the world and at its precipitious plunge into isolation when a new emperor ascended the Dragon Throne. During the brief period from 1405 to 1433, seven epic expeditions brought China's treasure ships across the China Seas and the Indian Ocean, from Taiwan to the spice islands of Indonesia and the Malabar coast of India, on to the rich ports of the Persian Gulf and down the African coast, China'sEl Dorado, and perhaps even to Australia, three hundred years before Captain Cook was credited with its discovery. With over 300 ships--some measuring as much as 400 feet long and 160 feet wide, with upwards of nine masts and twelve sails, and combined crews sometimes numbering over 28,000men--the emperor Zhu Di's fantastic fleet was a virtual floating city, a naval expression of his Forbidden City in Beijing. The largest wooden boats ever built, these extraordinary ships were the most technically superior vessels in the world with innovations such as balanced rudders and bulwarkedcompartments that predated European ships by centuries. For thirty years foreign goods, medicines, geographic knowledge, and cultural insights flowed into China at an extraordinary rate, and China extended its sphere of political power and influence throughout the Indian Ocean. Half the world was inChina's grasp, and the rest could easily have been, had the emperor so wished. But instead, China turned inward, as suceeding emperors forbade overseas travel and stopped all building and repair of oceangoing junks. Disobedient merchants and seamen were killed, and within a hundred years thegreatest navy the world had ever known willed itself into extinction. The period of China's greatest outward expansion was followed by the period of its greatest isolation. Drawing on eye-witness accounts, official Ming histories, and African, Arab, and Indian sources, many translated for the first time, Levathes brings readers inside China's most illustrious scientific and technological era. She sheds new light on the historical and cultural context in which thisgreat civilization thrived, as well as the perception of other cultures toward this little understood empire at the time. Beautifully illustrated and engagingly written, When China Ruled the Seas is the fullest picture yet of the early Ming Dynasty--the last flowering of Chinese culture before theManchu invasions.

    It is iconoclastic, crosses disciplinary boundaries, and finally it is calm and compellingly reasonable. The book was widely read on both sides of the Iron Curtain and the result was serious revision in both Western and Soviet strategy and doctrine. As a result, both sides were better able to avoid disaster during the Cold War.The strategic concepts still apply: defense, local animosities, and the usual balance-of-power issues are still very much with us. Kahn's stated purpose in writing this book was simply: "avoiding disaster and buying time, without specifying the use of this time." By the late 1950s, with both sides H-bomb-armed, reason and time were in short supply.Kahn, a military analyst at Rand since 1948, understood that a defense based only on thermonuclear arnaments was inconceivable, morally questionable, and not credible.The book was the first to make sense of nuclear weapons. Originally created from a series of lectures, it provides insight into how policymakers consider such issues. One may agree with Kahn or disagree with him on specific issues, but he clearly defined the terrain of the argument. He also looks at other weapons of mass destruction such as biological and chemical, and the history of their use.The Cold War is over, but the nuclear genie is out of the bottle, and the lessons and principles developed in On Thermonuclear War apply as much to today's China, Russia, Iran, and North Korea as they did to the Soviets.

    Whether you were the king's court astrologer or a farmer marking the best time for planting, timekeeping and numbers really mattered. Mistake a numerical pattern of petals and you could be poisoned. Lose the rhythm of a sacred dance or the meter of a ritually told story and the intricately woven threads that hold life together were spoiled. Ignore the celestial clock of equinoxes and solstices, and you'd risk being caught short of food for the winter. Shesso's friendly tone and clear grasp of the information make the math "go down easy" in this marvelous book.BONUS: This book has over 100 illustrations!

Many ancient cultures had specific gods and goddesses they credited with inventing mathematical skills. With the aid of divine inspiration and assistance, humans nourished this numerical invention, continually pushing their skills and seeking greater clarity of expression. “Our starting point may seem like a Zero. But for now, before looking at numbers and math, let’s simply see it as a circle. No matter what our spiritual practice, we each live within the circle of creation, each within the circle—the cohesiveness—of our own form...” From John Michael Greer, Grand Archdruid, Ancient Order of Druids in America and author of The Druidry Handbook:“As thoughtful as it is readable, Renna Shesso’s Math for Mystics is the book I wish I had when I first started trying to make sense of the mathematics that underlie so much of modern magic and traditional occult lore. Not the least of its virtues is the way it makes magical number theory accessible even to those who think they don’t like or can’t handle math. It provides a first-rate introduction to a fairly neglected branch of magical lore.”

    However, according to Hofstadter, the formal system that underlies all mental activity transcends the system that supports it. If life can grow out of the formal chemical substrate of the cell, if consciousness can emerge out of a formal system of firing neurons, then so too will computers attain human intelligence. Gödel, Escher, Bach is a wonderful exploration of fascinating ideas at the heart of cognitive science: meaning, reduction, recursion, and much more.

    The era covered by this book, 1950 to 1990, was surely one of the golden ages of science as well as the American university.Cherished myths are debunked along the way as Gian-Carlo Rota takes pleasure in portraying, warts and all, some of the great scientific personalities of the period Stanislav Ulam (who, together with Edward Teller, signed the patent application for the hydrogen bomb), Solomon Lefschetz (Chairman in the 50s of the Princeton mathematics department), William Feller (one of the founders of modern probability theory), Jack Schwartz (one of the founders of computer science), and many others.Rota is not afraid of controversy. Some readers may even consider these essays indiscreet. After the publication of the essay "The Pernicious Influence of Mathematics upon Philosophy" (reprinted six times in five languages) the author was blacklisted in analytical philosophy circles. Indiscrete Thoughts should become an instant classic and the subject of debate for decades to come."Read Indiscrete Thoughts for its account of the way we were and what we have become; for its sensible advice and its exuberant rhetoric."--The Mathematical Intelligencer"Learned, thought-provoking, politically incorrect, delighting in paradox, and likely to offend but everywhere readable and entertaining."--The American Mathematical Monthly"It is about mathematicians, the way they think, and the world in which the live. It is 260 pages of Rota calling it like he sees it... Readers are bound to find his observations amusing if not insightful. Gian-Carlo Rota has written the sort of book that few mathematicians could write. What will appeal immediately to anyone with an interest in research mathematics are the stories he tells about the practice of modern mathematics."--MAA Reviews"

    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.

    A historian and journalist who was one of the earliest and staunchest Afrikaner opponents of apartheid, Hermann Giliomee weaves together life stories and historical interpretation to create a narrative history of the Afrikaners from their beginnings with the colonization of the Cape of Good Hope by the Dutch East India Company to the dismantling of apartheid and beyond. The Afrikaners emphasizes the crucial role played by historical actors without underplaying the impact of social forces over which they had little control. Throughout their history, Giliomee's Afrikaners are both colonizers and colonized. Actual or virtual servants of the Dutch East India Company, the Dutch "burghers" nonetheless owned slaves and commanded servant labor. The British conquests of 1795 and 1806 extended the rights of British subjects to Afrikaners, even as they took away the Afrikaners' political autonomy and confirmed an economic and cultural subordination that was only partly alleviated by their dominance of South African politics in the latter part of the twentieth century.Demographically squeezed between far more numerous Africans (and other nonwhite groups) and their more affluent and culturally confident English compatriots, the Afrikaners forged a language-based national identity in which die-hard defense of privilege and opposition to various forms of British domination are inextricably intertwined with fears about cultural and even physical group survival. This nationalism underlay the Great Trek, in which Afrikaners opposed the abolition of slavery and legalized racial discrimination by the British; the irony of their becoming the twentieth century's first fighters against imperial domination in the Boer War; and the Afrikaners' rise to political dominance over their English rivals and nonwhite South Africans alike, even as they remained economically and culturally subordinate to the former. This same language-based nationalism spawned the blunders and horrors of apartheid, but it also led the Afrikaners to relinquish power peacefully when this seemed the safest route to their survival as a people.While documenting--and in important ways revising--the history of the Afrikaners' pursuit of racial domination (as well as British contributions to that enterprise), Giliomee supplies Afrikaners' own, often divided, perspectives on their history, perspectives not always or entirely skewed by their struggle for privilege at Africans' expense. The result is not only a magisterial history of the Afrikaners but a fuller understanding of their history, which, for good or ill, resonates far beyond the borders of South Africa.

    By locating social movements in history, prize-winning social scientist Charles Tilly provides rich and often surprising insights into the origins of contemporary social movement practices, relations of social movements to democratization, and likely futures for social movements.

    The story of information begins in a time profoundly unlike our own, when every thought and utterance vanishes as soon as it is born. From the invention of scripts and alphabets to the long-misunderstood talking drums of Africa, Gleick tells the story of information technologies that changed the very nature of human consciousness. He provides portraits of the key figures contributing to the inexorable development of our modern understanding of information: Charles Babbage, the idiosyncratic inventor of the first great mechanical computer; Ada Byron, the brilliant and doomed daughter of the poet, who became the first true programmer; pivotal figures like Samuel Morse and Alan Turing; and Claude Shannon, the creator of information theory itself. And then the information age arrives. Citizens of this world become experts willy-nilly: aficionados of bits and bytes. And we sometimes feel we are drowning, swept by a deluge of signs and signals, news and images, blogs and tweets. The Information is the story of how we got here and where we are heading.

    A brilliantly clear and penetrating exposition of developments in physical science and mathematics brought about by the advent of non-Euclidean geometries, including in-depth coverage of the foundations of geometry, the theory of time, Einstein's theory of relativity and its consequences, other key topics.

    This is an account of the world's greatest ‘intellectual virtuosos,' who are also humanity's greatest doubters and disbelievers, from the ancient Greek philosophers, Jesus, and the Eastern religions, to modern secular equivalents Marx, Freud and Darwin—and their attempts to reconcile the seeming meaninglessness of the universe with the human need for meaning,This remarkable book ranges from the early Greeks, Hebrew figures such as Job and Ecclesiastes, Eastern critical wisdom, Roman stoicism, Jesus as a man of doubt, Gnosticism and Christian mystics, medieval Islamic, Jewish and Christian skeptics, secularism, the rise of science, modern and contemporary critical thinkers such as Schopenhauer, Darwin, Marx, Freud, Nietzsche, the existentialists.

    George Saliba follows the rise and fall of the Islamic scientific tradition, and the relationship of Islamic science to European science during the Renaissance.

    Following closely behind is y, or gamma, a constant that arises in many mathematical areas yet maintains a profound sense of mystery. In a tantalizing blend of history and mathematics, Julian Havil takes the reader on a journey through logarithms and the harmonic series, the two defining elements of gamma, toward the first account of gamma's place in mathematics. Introduced by the Swiss mathematician Leonhard Euler (1707-1783), who figures prominently in this book, gamma is defined as the limit of the sum of 1 + 1/2 + 1/3 + . . . Up to 1/n, minus the natural logarithm of n--the numerical value being 0.5772156. . . . But unlike its more celebrated colleagues π and e, the exact nature of gamma remains a mystery--we don't even know if gamma can be expressed as a fraction. Among the numerous topics that arise during this historical odyssey into fundamental mathematical ideas are the Prime Number Theorem and the most important open problem in mathematics today--the Riemann Hypothesis (though no proof of either is offered!). Sure to be popular with not only students and instructors but all math aficionados, Gamma takes us through countries, centuries, lives, and works, unfolding along the way the stories of some remarkable mathematics from some remarkable mathematicians.-- "Notices of the American Mathematical Society"

    Yet it has not been an easy path; military catastrophe, political atrophy, and economic upheavals have made regular appearances from the feudal era to the present. Today, Japan is seen as a has-been with a sluggish economy, an aging population, dysfunctional politics, and a business landscape dominated by yesterday's champions. Though it is supposed to be America's strongest ally in the Asia-Pacific region, it has almost entirely disappeared from the American radar screen.In Japan and the Shackles of the Past, R. Taggart Murphy places the current troubles of Japan in a sweeping historical context, moving deftly from early feudal times to the modern age that began with the Meiji Restoration. Combining fascinating analyses of Japanese culture and society over the centuries with hard-headed accounts of Japan's numerous political regimes, Murphy not only reshapes our understanding of Japanese history, but of Japan's place in the contemporary world. He concedes that Japan has indeed been out of sight and out of mind in recent decades, but contends that this is already changing. Political and economic developments in Japan today risk upheaval in the pivotal arena of Northeast Asia, inviting comparisons with Europe on the eve of the First World War. America's half-completed effort to remake Japan in the late 1940s is unraveling, and the American foreign policy and defense establishment is directly culpable for what has happened. The one apparent exception to Japan's malaise is the vitality of its pop culture, but it's actually no exception at all; rather, it provides critical clues to what is going on now.With insights into everything from Japan's politics and economics to the texture of daily life, gender relations, the changing business landscape, and popular and high culture, Japan and the Shackles of the Past is the indispensable guide to understanding Japan in all its complexity.
