Yet Vikings were also traders, settlers, and farmers, with a complex artistic and linguistic culture, whose expansion overseas led them to cross the Atlantic for the first time in European history. Highlighting the latest archaeological evidence, Julian Richards reveals the whole Viking world: their history, their culture, and their legacy of overseas expansion for trade, colonization, and plunder. Viking identity is explored through what we have learned about their towns, art, shipbuilding, and religious rituals. Here the Viking story is brought up to the present, from the tales of adventure found in medieval Icelandic sagas, to their exploitation as a symbol of nationalism in the nineteenth century by Wagner, and later by Hitler and the Nazi party. The author also highlights their impact and influence on the history and people of Northern Europe. Vikings, a fascinating new look at a people and culture that have been reinvented throughout history, will take readers closer to discovering who they really were.

    It is impossible to understand the spread of an epidemic, a computer virus, large-scale blackouts, or massive extinctions without taking into account the network structure that underlies all these phenomena. In this Very Short Introduction, Guido Caldarelli and Michele Catanzaro discuss the nature and variety of networks, using everyday examples from society, technology, nature, and history to explain and understand the science of network theory. They show the ubiquitous role of networks; how networks self-organize; why the rich get richer; and how networks can spontaneously collapse. They conclude by highlighting how the findings of complex network theory have very wide and important applications in genetics, ecology, communications, economics, and sociology.

    Indeed, without religion, our lives are left without meaning and are likely to degenerate into moral chaos. In this Very Short Introduction, philosopher Stephen Law explains why these claims are false and why humanism--though a rejection of religion--nevertheless provides both a moral basis and a meaning for our lives. Indeed, Law shows that humanism is a quite positive alternative to religion. The humanist is not simply one who denies the truth of religious belief, but one who believes we can enjoy meaningful, purposeful, and good lives without religion. And far from embracing moral nihilism, humanists are often deeply committed people, to be found at the forefront of many important ethical campaigns. Law goes on to show how the term humanism is used in a variety of ways. Marx described himself as a humanist but the Pope has also expressed support for what he calls humanism. Law argues for humanism as it is most commonly understood--as a positive, moral form of atheism.

    It explains what algorithms do, how they are used, the risks associated with using them, and why governments should be concerned.

    In an age where we've mapped the human genome and explored much of the physical world, the study of people's behaviour is one of the most exciting frontiers of scientific endeavor.In this Very Short Introduction Richard Crisp tells the story of social psychology, its history, concepts and major theories. Discussing the classic studies that have defined the discipline, Crisp introduces social psychology's key thinkers, and shows how their personal histories spurred them to understand what connects people to people, and the societies in which we live. Taking us from the first ideas of the discipline to its most cutting edge developments, Crisp demonstrates how social psychology remains profoundly relevant to everyday life. From attitudes to attraction, prejudice to persuasion, health to happiness - social psychology provides insights that can change the world, and help us tackle the defining problems of the 21st century.ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area.

    When a scholar as careful and learned as Mr. Kennedy is prompted by contemporary issues to reexamine the great processes of the past, the result can only be an enhancement of our historical understanding.... When the study is written as simply and attractively as this work is, its publication may have a great and beneficient impact. It is to be hoped that Mr. Kennedy's will have one, at a potentially decisive moment in America's history."Michael Howard, The New York Times Book Review"Important, learned, and lucid... Paul Kennedy's great achievement is that he makes us see our current international problems against a background of empires that have gone under because they were unaible to sustain the material cost of greatness; and he does so in a universal historical perspective of which Ranke would surely have approved."James Joll, The New York Review of Books"His strategic-economic approach provides him with the context for a shapely narrative....Professor Kennedy not only exploits his framework eloquently, he also makes use of it to dig deeper and explore the historical contexts in which some 'power centers' prospered....But the most commanding purpose of his project...is the lesson he draws from 15 centuries of statecraft to apply to the present scene....[The book's] final section is for everyone concerned with the contemporary political scene."Christopher Lehmann-Haupt, The New York Times"Kennedy gives epic meaning to the nation's relative economic and industrial decline."

    It proposes enlightening similarities between, for instance, maneuvering in limited war and in a traffic jam; deterring the Russians and one's own children; the modern strategy of terror and the ancient institution of hostages.

    But how can it be defined? In this highly readable introduction the mysteries of this most elusive of concepts are unraveled, casting a critical light upon the way we live now, from the politicizing of museumculture to the cult of the politically correct. The key postmodernist ideas are explored and challenged, as they figure in the theory, philosophy, politics, ethics and artwork of the period, and it is shown how they have interacted within a postmodernist culture.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics.

    Growing understanding of the immune system, and especially the creation of immune memory (long lasting protection), which can be harnessed in the design of vaccines, have been major breakthroughs in medicine.In this Very Short Introduction, Paul Klenerman describes the immune system, and how it works in health and disease. In particular he focuses on the human immune system, considering how it evolved, the basic rules that govern its behavior, and the major health threats where it is important. Theimmune system comprises a series of organs, cells and chemical messengers which work together as a team to provide defence against infection. Klenerman discusses these components, the critical signals that trigger them and how they exert their protective effects, including so-called innate immuneresponses, which react very fast to infection, and adaptive immune responses, which have huge diversity and a capacity to recognize and defend against a massive array of micro-organisms. Klenerman also considers what happens when our immune systems fail to be activated effectively, leading toserious infections, problems with inherited diseases, and also HIV/AIDS. At the opposite extreme, as Klenerman shows, an over-exaggerated immune response leads to inflammatory diseases such as Multiple Sclerosis and Rheumatoid Arthritis, as well as allergy and asthma. Finally he looks at the Immunesystem v2.o - how immune therapies and vaccines can be advanced to protect us against the major diseases of the 21st century.ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area.

    It examines the impact of the revolution on society as a whole--on different classes, ethnic groups, the army, men and women, youth. Its centralconcern is to understand how one structure of domination was replaced by another. The book registers the primacy of politics, but situates political developments firmly in the context of massive economic, social, and cultural change. Since the fall of Communism there has been much reflection on thesignificance of the Russian Revolution. The book rejects the currently influential, liberal interpretation of the revolution in favor of one that sees it as rooted in the contradictions of a backward society which sought modernization and enlightenment and ended in political tyranny.

    Looking at texts ranging from the Gospels from NagHammadi to the Dialogues with the Risen Savior, Paul Foster shows how the apocryphal gospels reflect the diversity that existed within early Christianity, and considers the extent to which they can be used to reconstruct an accurate portrait of the historical Jesus. Foster demonstrates how closeanalysis of text, contents, and context are vital in assessing the value and authenticity of such ancient documents. Including discussions of controversies and case-studies such as the alleged hoax surrounding the discovery of Secret Mark, Foster concludes that the non-canonical texts, considered inthe correct context, can help us reach a more complete understanding of the multi-faceted nature of early Christianity.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics.

    Kaplan, the bestselling author of Monsoon and Balkan Ghosts, offers a revelatory new prism through which to view global upheavals and to understand what lies ahead for continents and countries around the world.   In The Revenge of Geography, Kaplan builds on the insights, discoveries, and theories of great geographers and geopolitical thinkers of the near and distant past to look back at critical pivots in history and then to look forward at the evolving global scene. Kaplan traces the history of the world’s hot spots by examining their climates, topographies, and proximities to other embattled lands. The Russian steppe’s pitiless climate and limited vegetation bred hard and cruel men bent on destruction, for example, while Nazi geopoliticians distorted geopolitics entirely, calculating that space on the globe used by the British Empire and the Soviet Union could be swallowed by a greater German homeland.   Kaplan then applies the lessons learned to the present crises in Europe, Russia, China, the Indian subcontinent, Turkey, Iran, and the Arab Middle East. The result is a holistic interpretation of the next cycle of conflict throughout Eurasia. Remarkably, the future can be understood in the context of temperature, land allotment, and other physical certainties: China, able to feed only 23 percent of its people from land that is only 7 percent arable, has sought energy, minerals, and metals from such brutal regimes as Burma, Iran, and Zimbabwe, putting it in moral conflict with the United States. Afghanistan’s porous borders will keep it the principal invasion route into India, and a vital rear base for Pakistan, India’s main enemy. Iran will exploit the advantage of being the only country that straddles both energy-producing areas of the Persian Gulf and the Caspian Sea. Finally, Kaplan posits that the United States might rue engaging in far-flung conflicts with Iraq and Afghanistan rather than tending to its direct neighbor Mexico, which is on the verge of becoming a semifailed state due to drug cartel carnage.   A brilliant rebuttal to thinkers who suggest that globalism will trump geography, this indispensable work shows how timeless truths and natural facts can help prevent this century’s looming cataclysms.

    As humans, we decipher the meaning of newspaper articles, books, legal matters, religious texts, political speeches, emails, and even dinner conversations every day . But how is knowledge mediated through these forms? What constitutes the process of interpretation? And how do we draw meaning from the world around us so that we might understand ourposition in it?In this Very Short Introduction Jens Zimmermann traces the history of hermeneutic theory, setting out its key elements, and demonstrating how they can be applied to a broad range of disciplines: theology; literature; law; and natural and social sciences. Demonstrating the longstanding and wide-ranging necessity of interpretation, Zimmermann reveals its significance in our current social and political landscape.ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area.
