    It has been explained as a combination of romance, science and prophecy; as a genre based on an imagined alternative to the reader's environment; and as a form of fantastic fiction and historical literature. It has also been argued that science fiction narratives are the most engaged, socially relevant, and responsive to the modern technological environment. This Very Short Introduction doesn't offer a history of science fiction, but instead ties examples of science fiction to different historical moments, in order to demonstrate how science fiction has evolved over time. David Seed looks not only at literature, but also at drama and poetry, as well as film. Examining recurrent themes in science fiction he looks at voyages into space, the concept of the alien and alternative social identities, the role of technology in science fiction, and its relation to time - in the past, present, and future.

    From deserts to jungles, from deep caves to mountain tops, from pebble tools to satellite photographs, from excavation to abstract theory, archaeology interacts with nearly every other discipline in its attempts to reconstruct the past.

    Nearly every regime today claims to be democratic, but not all democracies allow free politics, and free politics existed long before democratic franchises. This book is a short account of the history of the doctrine and practice of democracy, from ancient Greece and Rome through the American, French, and Russian revolutions, and of the usages and practices associated with it in the modern world. It argues that democracy is a necessary but not asufficient condition for good government, and that ideas of the rule of law, and of human rights, should in some situations limit democratic claims.

    It is truly a vital field, central to the health of society, but it is often poorly understood, largely due to misrepresentations in the media. In this Very Short Introduction, an internationally recognized authority on epidemiology, Dr. Rodolfo Saracci, provides a wealth of information on this key field, dispelling some of the myths surrounding the study of epidemiology, and explaining what epidemiology is and how vital it is to the discovery, control, and prevention of disease in world populations. Dr. Saracci provides a general explanation of the principles behind clinical trials, and explains the nature of basic statistics concerning disease. He also looks at the ethical and political issues related to obtaining and using information concerning patients, and trials involving placebos.

    Each chapter addresses a central scientific issue but does so in a way that is lively and completely accessible. Issues discussed include whether there are several different types of intelligence, whether intelligence differences are caused by genes or the environment, the biological basis of intelligence levels, and whether intelligence declines as we grow older.

    Negotiations for the accession of six new states have begun, and membership, which already covers almost all of Western Europe, will soon extend to most of Central and Eastern Europe. The Union's institutions have been reformed, and its powers may soon reach beyond the economy and the environment into the fields of foreign policy and defense. This thorough yet succinct introduction has been completely updated to take the many recent developments into account. John Pinder provides a detailed and coherent view of the evolution of the European Union, and investigates its future as Europe thrives in the new millennium.

    Scerri looks at the trends in properties of elements that led to the construction of the periodic table, and how the deeper meaning of its structure gradually became apparent with the development of atomic theory and quantum mechanics, so that physics arguably came to colonize an entirely different science, chemistry.

    Despite civil rights movements and other attempts at progress, racial prejudices and stereotypes remain deeply embedded in Western culture. Racism takes a frank and objective look at why these notions exist. It explores how racism has come to be so firmly established, and looks at how race, ethnicity, and xenophobia are related. This book incorporates the latest research to demystify the subject of racism and explore its history, science, and culture. It sheds light not only on how racism has evolved since its earliest beginnings, but also explores the numerous embodiments of racism, highlighting the paradox of its survival, despite the scientific discrediting of the notion of 'race' with the latest advances in genetics. As encompassing as it is concise, Racism is a valuable guide to one of the world's most destructive problems.

    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.

    Featuring many striking photos, this Very Short Introduction offers a fascinating portrait of the unique world of each planet as well as an illuminating discussion of moons, asteroids, and Trans-Neptunian objects. Leading planetary scientist David A. Rothery, who has chaired the European Space Agency's Mercury surface and composition working group since 2007, gives a stimulating overview of the origin, nature, and evolution of our Solar System, including the controversial issues of what qualifies as a planet, and what conditions are required for a planetary body to support life. He explains how the surfaces of planets and moons have been sculpted by geology, weather, and impacts by meteors and asteroids. Rothery shows how our knowledge has advanced over the centuries, and how it has expanded at a dramatic rate in recent years, going far beyond our Solar System to explore planets orbiting distant stars.

    Not only are galaxies fascinatingastronomical structures in themselves, but their study has revealed much of what we know today about the cosmos, providing a window on the Big Bang and the origins of the Universe. Gribben looks at our own Milky Way Galaxy in detail, from the different kinds of stars that are born within it, tothe origins of its magnificent spiral structure. Perhaps most interesting, Gribben describes the many exciting discoveries have been made about our own galaxy and about those beyond: how a supermassive black hole lurks at the center of every galaxy, how enormous forces are released when galaxiescollide, how distant galaxies provide a window on the early Universe, and how the formation of young galaxies shed needed light on the mysteries of Cold Dark Matter.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics.

    Between 1400 and 1600, European perceptions of society, culture, politics and even humanity itself emerged in ways that continue to affect not only Europe but the entire world. In this wide-ranging exploration of the Renaissance, Jerry Brotton shows the period as a time of unprecedented intellectual excitement, cultural experimentation, and interaction on a global scale, alongside a darker side of religion, intolerance, slavery, and massive inequality of wealth and status. Brotton skillfully guides us through the key issues that defined the Renaissance period, from its art, architecture, and literature, to advancements in the fields of science, trade, and travel. In its incisive account of the complexities of the political and religious upheavals of the period, the book argues that there are significant parallels between the Renaissance and our own era. This is the first clear and concise account of the Renaissance as a global phenomenon, an important new vision of the Renaissance for the 21st century written by a young Renaissance scholar of a new generation.

    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. The main text makes no use of equations, but there is a Mathematical Appendix for those desiring stronger fare. Uncertainty, probabilistic physics, complementarity, the problematic character of measurement, and decoherence are among the many topics discussed. This volume offers the reader access to one of the greatest discoveries in the history of physics and one of the outstanding intellectual achievements of the twentieth century.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics.
