    In this Very Short Introduction, Robert C. Allen shows how the interplay of geography, globalization, technological change, and economic policy has determined the wealth and poverty of nations. Allen shows how the industrial revolution was Britain's path-breaking response to the challenge of globalization. Western Europe and North America joined Britain to form a club of rich nations, pursuing four polices--creating a national market by abolishing internal tariffs and investing in transportation, erecting an external tariff to protect their fledgling industries from British competition, creating banks to stabilize the currency and mobilize domestic savings for investment, and promoting mass education to prepare people for industrial work. Together these countries pioneered new technologies that have made them ever richer. A few countries--Japan, Soviet Russia, South Korea, Taiwan, and perhaps China--have caught up with the West through creative responses to the technological challenge and with Big Push industrialization that has achieved rapid growth through coordinated investment.

    This book gives a lucid, exciting, and accessible account of the surprising and counterintuitive ideas that shape our understanding of the sub-atomic world. It does not disguise the problems of interpretation that still remain unsettled 75 years after the initial discoveries.

    It is structured around six schools of thought that have received classic status. Sue Hamilton explores how the traditions have attempted to understand the nature of reality in terms of inner or spiritual quest and introduces distinctively Indian concepts, such as karma and rebirth. She also explains how Indian thinkers have understood issues of reality and knowledge--issues that are also an important part of the Western philosophical tradition.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics.

Ferber offers a definition and several general propositions about this very diverse movement, as well as a discussion of the word Romantic and where it came from. Finally, some two hundred authors or artists are cited or quoted, many at length, including Blake, Wordsworth, Coleridge, Byron, Shelley, Keats, Emerson, Hugo, Goethe, Pushkin, Beethoven, Berlioz, Chopin, and Delacroix.

    This Very Short Introduction discusses both the history and key debates of postcolonialism, and considers its importance as a means of changing the way we think about the world.Robert J. C. Young examines the key strategies that postcolonial thought has developed to engage with the impact of sometimes centuries of western political and cultural domination. Situating the discussion in a wide cultural and geographical context, he draws on examples such as the status of indigenous peoples, of those dispossessed from their land, Algerian rai music, and global social and ecological movements. In this new edition he also includes updated material on race, slavery, and postcolonial gender politics. Above all, Young argues that postcolonialism offers a political philosophy of activism that contests the current situation of global inequality, which in a new way continues the anti-colonial struggles of the past and enables us to decolonize our own lives in the present.ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area These pocket-sized books are the perfect way to get ahead in a new subject quickly Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable

    While there are distinctive themes and emphases that emerge from its early history and theology, there is little sense of unity in Anglicanism today.Here, Mark Chapman explores the fascinating history, theology, and structures of Anglicanism, and highlights the diversity of the contemporary church by examining how traditions vary from England and American, from South Africa to Malaysia.

    Even today, the war inspires countless articles and books, extensive archaeological excavations, movies, television documentaries, even souvenirs and collectibles. Butwhile the ancients themselves believed that the Trojan War took place, scholars of the modern era have sometimes derided it as a piece of fiction.Combining archaeological data and textual analysis of ancient documents, this Very Short Introduction considers whether or not the war actually took place and whether archaeologists have really discovered the site of ancient Troy. To answer these questions, archaeologist and ancient historian EricH. Cline examines various written sources, including the works of Homer, the Epic Cycle (fragments from other, now-lost Greek epics), classical plays, and Virgil's Aeneid. Throughout, the author tests the literary claims against the best modern archaeological evidence, showing for instance thatHomer, who lived in the Iron Age, for the most part depicted Bronze Age warfare with accuracy. Cline also tells the engaging story of the archaeologists--Heinrich Schliemann and his successors Wilhelm Dörpfeld, Carl Blegen, and Manfred Korfmann--who found the long-vanished site of Troy throughexcavations at Hisarlik, Turkey.Drawing on evidence found at Hisarlik and elsewhere, Cline concludes that a war or wars in the vicinity of Troy probably did take place during the Late Bronze Age, forming the nucleus of a story that was handed down orally for centuries until put into final form by Homer. But Cline suggests that, even allowing that a Trojan War took place, it probably was not fought because of Helen's abduction, though such an incident may have provided the justification for a war actually fought for more compelling economic and political motives.About the Series: Oxford's Very Short Introductions series offers concise and original introductions to a wide range of subjects--from Islam to Sociology, Politics to Classics, Literary Theory to History, and Archaeology to the Bible.

    Blundell illuminates the mysterious force of magnetism. For centuries, magnetism has been used for various purposes—through compasses it gave us the ability to navigate, and through motors, generators, and turbines, it has given us power. Blundell explores our understanding of electricity and magnetism, from the work of Galvani, Ampère, Faraday, and Tesla, and describes how Maxwell and Faraday's work led to the unification of electricity and magnetism—one of the most imaginative developments in theoretical physics. Finally, he discusses the relationship between magnetism and relativity, quantum magnetism, and its impact on computers and information storage, showing how magnetism has changed our fundamental understanding of the Universe.
