The authors introduce the general reader to some of the most important basic findings, concepts, and procedures of evolutionary biology, as it has developed since the first publications of Darwin and Wallace on the subject, over 140 years ago. They show how evolution provides a unifying set of principles for the whole of biology and sheds light on the relation of human beings to the universe and each other.

    Travel fast enough and you could weigh as much as a jumbo jet, be flattened thinner than a CD without feeling a thing-and live forever! As for the angles of a triangle, they do not always have to add up to 180 degrees. And then, of course, there are black holes. These are but a few of the extraordinary consequences of Einstein's theory of relativity. It is now over a hundred years since he made these discoveries, and yet the general public is still largely unaware of them. Filled with illuminating anecdotes and fascinating accounts of experiments, this book aims to introduce the interested lay person to the subject of relativity in a way which is accessible and engaging and at the same time scientifically rigorous. With relatively few mathematical equations--nothing more complicated than the Pythagoras's Theorem--this VSI packs a lot time into very little space, and for anyone who has felt intimidated by Einstein's groundbreaking theory, it offers the perfect place to start.

    The results of Artificial Intelligence have been invaluable to biologists, psychologists, and linguists in helping tounderstand the processes of memory, learning, and language from a fresh angle.As a concept, Artificial Intelligence has fueled and sharpened the philosophical debates concerning the nature of the mind, intelligence, and the uniqueness of human beings. In this Very Short Introduction, Margaret A. Boden reviews the philosophical and technological challenges raised by ArtificialIntelligence, considering whether programs could ever be really intelligent, creative, or even conscious, and shows how the pursuit of Artificial Intelligence has helped us to appreciate how human and animal minds are possible.ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area.

    Here, Timothy Lim explores the cultural and historical background of the scrolls, and examines their significance for our understanding of the Old Testament and the origins of Christianity and Judaism. Lim tells the fascinating story of the scrolls since their discouvery; their cultural context through the archaeology and history of the Dead Sea region. He explains the science behind their deciphering and dating, and does not omit the cast of characters, scandals, and controversies that have hastened the scrolls' rise to the status of cultrual icon.Beginning with their discovery in the 1940s, through the political, legal, and scholary controversies that still persist today, public interest in the Dead Sea Scrolls has remained exceptionally high. This is an accessible and well-written mini-history that will appeal to anyone interested in the true history of these fascinating documents.

    Readers meet a people highly skilled in sculpture, astronomy, city planning, poetry, and philosophy, who were also profoundly committed tocosmic regeneration through the thrust of the ceremonial knife and through warfare. Dav�d Carrasco looks beyond Spanish accounts that have colored much of the Western narrative to let Aztec voices speak about their origin stories, the cosmic significance of their capital city, their methods of childrearing, and the contributions women made to daily life and the empire. Carrasco discusses the arrival of the Spaniards, contrasts Aztec mythical traditions about the origins of their city with actual urban life in Mesoamerica, and outlines the rise of the Aztec empire. He also explores Aztecreligion, which provided both justification for and alternatives to warfare, sacrifice, and imperialism, and he sheds light on Aztec poetry, philosophy, painting, and especially monumental sculpture and architecture. He concludes by looking at how the Aztecs have been portrayed in Western thought, art, film, and literature as well as in Latino culture and arts.

    But how did they come to be here? What were their agricultural, spiritual, and hunting practices? How did their societies evolve and what challenges do they face today? Eminent historians Theda Perdue and Michael Green begin by describing how nomadic bands of hunter-gatherers followed the bison and woolly mammoth over the Bering land mass between Asia and what is now Alaska between 25,000 and 15,000 years ago, settling throughout North America. They describehunting practices among different tribes, how some made the gradual transition to more settled, agricultural ways of life, the role of kinship and cooperation in Native societies, their varied burial rites and spiritual practices, and many other features of Native American life. Throughout the book, Perdue and Green stress the great diversity of indigenous peoples in America, who spoke more than 400 different languages before the arrival of Europeans and whose ways of life varied according to the environments they settled in and adapted to so successfully. Most importantly, the authors stresshow Native Americans have struggled to maintain their sovereignty--first with European powers and then with the United States--in order to retain their lands, govern themselves, support their people, and pursue practices that have made their lives meaningful. Going beyond the stereotypes that so often distort our views of Native Americans, this Very Short Introduction offers a historically accurate, deeply engaging, and often inspiring account of the wide array of Native peoples in America.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics.

    This very short introduction to the condition offers a clear statement on what is currently known about autism and Asperger's syndrome.

    Indeed it could be said that all history is colonial history, if one takes a broad enough definition and goes far enough back. And although the great historic imperial systems--the land-based Russian one as well as the seaborneempires of western European powers--have collapsed during the past half century, their legacies shape almost every aspect of life on a global scale. Meanwhile there is fierce argument, and much speculation, about what has replaced the old territorial empires in world politics. Do the United Statesand its allies, transnational companies, financial and media institutions, or more broadly the forces of globalization, constitute a new imperial system?Stephen Howe interprets the meaning of the idea of empire through the ages, disentangling the multiple uses and abuses of the labels empire and colonialism, etc., and examines the aftermath of imperialism on the contemporary world.

    But as Morris Rossabi reveals in this VeryShort Introduction, within two generations of their bloody conquests, the Mongols evolved from conquerors and predators to wise rulers who devised policies to foster the economies of the lands they had subjugated. By adopting political and economic institutions familiar to the local populations andrecruiting native officials, they won over many of their non-Mongol subjects. In addition, Mongol nobles were ardent patrons of art and culture, supporting the production of Chinese porcelains and textiles, Iranian tiles and illustrated manuscripts, and Russian metalwork. Perhaps most important, thepeace imposed by the Mongols on much of Asia and their promotion of trade resulted in considerable interaction among merchants, scientists, artists, and missionaries of different ethnic groups--including Europeans. Modern Eurasian and perhaps global history starts with the Mongol empire.

    In this Very Short Introduction, Thomas Forrest Kelly provides not only a compact overview of the music itself, but also a lively look at the many attempts over the last two centuries to revive it. Kelly shows that the early-music revival has long been grounded in the idea of spontaneity, of excitement, and of recapturing experiences otherwise lost to us--either the rediscovery of little-known repertories or the recovery of lost performing styles, with the conviction that, with the right performance, the music will come to life anew. Blending musical and social history, he shows how the Early Music movement in the 1960s took on political overtones, fueled by a rebellion against received wisdom and enforced conformity. Kelly also discusses ongoing debates about authenticity, the desirability of period instruments, and the relationship of mainstream opera companies and symphony orchestras to music that they often ignore, or play in modern fashion.
