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.

    New ideas and discoveries not only redefined what human beings believed, knew, and could do, but also forced them to redefine themselves with respect to the strange new worlds revealed by ships and scalpels, telescopes and microscopes, experimentation and contemplation. Explanatory systems were made, discarded, and remade by some of the best-known names in the entire history of science--Copernicus, Galileo, Newton--and by many others less recognized but no less important. In this Very Short Introduction Lawrence M. Principe explores the exciting developments in the sciences of the stars (astronomy, astrology, and cosmology), the sciences of earth (geography, geology, hydraulics, pneumatics), the sciences of matter and motion (alchemy, chemistry, kinematics, physics), the sciences of life (medicine, anatomy, biology, zoology), and much more. The story is told from the perspective of the historical characters themselves, emphasizing their background, context, reasoning, and motivations, and dispelling well-worn myths about the history of science.

    And yet it has excused, and even been thought to justify, the most reprehensible crimes. Why should this be? This Very Short Introduction explores this and other puzzling questions. Do we love someone for their virtue, their beauty, or their moral or other qualities? Are love's characteristic desires altruistic or selfish? Are there duties of love? What do the sciences - neuroscience, evolutionary and social psychology, and anthropology - tell us about love? Many of the answers we give to such questions are determined not so much by the facts of human nature as by the ideology of love. Ronald de Sousa considers some of the many paradoxes raised by love, looking at the different kinds of love - affections, affiliation, philia, storage, agape, but focusses on eros, or romantic love. He considers whether our conventional beliefs about love and sex are deeply irrational and argues that alternative conceptions of love and sex, although hard to formulate and live by, may be worth striving for.

    In this thought-provoking exploration of the subject, Steve Edwards provides a clear, lively, and imaginative approach to the definition, importance, and meaning of photography. He combines a sense of its historical development with an analysis of its purpose and meaning within a wider cultural context. Edwards also discusses both well-known and more unusual photos, from the highly controversial Cottingley Fairies to Ansel Adams landscapes, and from the shocking and influential Eddie Adams image of a Vietcong suspect being executed to the portrait/performance art work of Cindy Sherman. Edwards interrogates the way we look and think about photographs, and considers such issues as truth and recording, objectivity and fine art, identity and memory.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 presents a succinct guide to the key episodes in that story - from the very origins of life four million years ago to the extraordinary diversity of species around the globe today.Beginning with an explanation of the controversies surrounding the birth of life itself, each following chapter tells of a major breakthrough that made new forms of life possible: including sex and multicellularity, hard skeletons, and the move to land. Along the way, we witness the greatest mass extinction, the first forests, the rise of modern ecosystems, and, most recently, conscious humans.Introducing ideas from a range of scientific disciplines, from evolutionary biology and earth history, to geochemistry, palaeontology, and systematics, Michael Benton explains how modern science pieces the evidence in this vast evolutionary puzzle together, to build up an accessible and up-to-date picture of the key developments in the history of life on earth.

    Yet it is rare to find someone prepared to defend all freedom of speech, especially if the views expressed are obnoxious or obviously false. So where do we draw the line? How important is our right to freedom of speech? In this accessible and up-to-date Very Short Introduction, Nigel Warburton covers a wide range of controversial free-speech issues, from Holocaust denial and pornography to the status of modern copyright law. The book offers a concise guide to many of the vexing issues concerning our right to speak freely, including: Should a civilized society set limits on freedom of speech? How can we balance free speech with the sensitivities of religious and minority groups? How have digital technology and the Internet changed the debate?

    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.

    Johnson, this brilliant, compact survey stretches across the centuries, exploring the major literary forms (poetry, novel, drama, essay and more), the many histories and theories of the very idea of literature, and the role of writers in shaping English, British, and post-imperial identities. Bate illuminates the work of Chaucer, Shakespeare, Wordsworth, Dickens, and many other major figures of English literature.

Ranging from children's literature to biography, this is an indispensable guide and an inspiration for anyone interested in England's magnificent literary heritage.

    It traces the history and cultural impact of the elements on humankind, and examines why people have long sought to identify thesubstances around them. The book includes chapters on particular elements such as gold, iron, and oxygen, showing how they shaped culture and technology. Looking beyond the Periodic Table, the author examines our relationship with matter, from the uncomplicated vision of the Greek philosophers, whobelieved there were four elements--earth, air, fire, and water--to the work of modern-day scientists in creating elements such as hassium and meitnerium. Packed with anecdotes, The Elements is a highly engaging and entertaining exploration of the fundamental question: what is the world made from?

    But he did not intend the metaphysics to stand apart from his scientific work, which included important investigations into physics, mathematics, and optics. In this book, Sorell shows that Descarates was, above all, an advocate and practitioner of the new mathematical approach to physics, and that he developed his philosophies to support his discoveries in the sciences.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics.

    First, geologists realized that the continents themselves were drifting across the surface of the globe and that oceans were being created and destroyed. Secondly, pictures of the entire planet were returned from space. Suddenly, the Earth began to be viewed as a single entity; a dynamic, interacting whole, controlled by complex processes we scarcely understood. This Introduction explores emerging geological research and explains how new advances in the understanding of plate tectonics, seismology, and satellite imagery have enabled us to begin to see the Earth as it actually is: dynamic and ever changing.

    Lyman Sargent discusses the role of utopianism in literature, and in the development of colonies and in immigration. The idea of utopia has become commonplace in social and political thought, both negatively and positively. Some thinkers see a trajectory from utopia to totalitarianism with violence an inevitable part of the mix. Others see utopia directly connected to freedom and as a necessary element in the fight against totalitarianism. In Christianity utopia is labelled as both heretical and as a fundamental part of Christian belief, and such debates are also central to such fields as architecture, town and city planning, and sociology among many othersSargent introduces and summarizes the debates over the utopia in literature, communal studies, social and political theory, and theology.ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area.
