This book describes what schizophrenia is really like, how the illness progresses, and the treatments that have been applied. It also summarizes the most up-to-date knowledge available about the biological bases of this disorder. Finally it attempts to give some idea of what it is like to have schizophrenia and what this disorder tells us about the relationship between mind and brain.

    Explaining the nature of genetic variation in the human population, how hereditary factors were identified as molecules of DNA, and how certain specific mutations can lead to disease, Slack highlights how DNA variants are used to trace human ancestry and migration, and can also be used by forensic scientists to identify individuals in crime. Slack also explores issues such as the role of genetic heritability and IQ as well as the changes that occur in the genes of populations during evolution. An ideal guide for anyone curious about what genes are and how genetics can be put to use, this Very Short Introduction demonstrates the ways in which the gene concept has been understood and used by molecular biologists, population biologists, and social scientists around the world.

    These, along with the introduction of the oral contraceptive, have altered all of our lives. There has also been an increase in the recreational use and abuse of drugs in the Western world. This Very Short Introduction gives a non-technical account of how drugs act on the body and how therapeutic drugs are developed and tested, then goes on to review both legal (prescription, alcohol, nicotine, and caffeine) and illegal drugs, and discuss current ideas about why some drugs are addictive, and whether drug laws need reform.

    As a concept and a practice, it has attracted the attention of theologians, anthropologists, psychologists, sociologists, artists, and historians over the centuries. This Very Short Introduction explains why. Magic has been defined in terms of the false religions of others, as an evolutionary stage in human thought, a universal state of mind, and a liberating expression of the imagination. For hundreds of millions of people today, no matter their religious persuasion, magic is a real force that helps them to overcome misfortune, poverty, and illness. Indeed, with magic as relevant today as it ever was, it raises questions about the meaning of human progress.

    In this Very Short Introduction, Michael Wood offers a wealth of insight into the nature of film, considering its role and impact on society as well as its future in the digital age. As Wood notes, film is many things, but it has become above all a means of telling stories through images and sounds. The stories are often quite false, frankly and beautifully fantastic, and they are sometimes insistently said to be true. Indeed, many condemn movies as an instrument of illusion, an emphatic way of seeing what is not there. And others celebrate the reverse: that film brings us closest to the world as it actually is. "Photography is truth," a character says in a film by Jean-Luc Godard. "And cinema is the truth twenty-four times per second." But they are stories in either case, and there are very few films, Wood observes, even in avant-garde art, that don't imply or quietly slip into narrative.

    Allen and Cowling start with the simple "prokaryotic" cell--cells with no nucleus--and show how the bodies of more complex plants and animals consist of billions of "eukaryotic" cells, of varying kinds, adapted to fill different roles--red blood cells, muscle cells, branched neurons. The authors also show that each cell is an astonishingly complex chemical factory, the activities of which we have only begun to unravel in the past fifty years.

    Jan Westerhoff shows that the question "what is real?" is not some esoteric puzzle that only philosophers ponder. Scientists also ask this question when they investigate whether candidates for the fundamental constituents of matter are actually "out there" or just a mere abstraction from a successful theory and cognitive scientists ask it when trying to find out which set of the bewildering array of data processed by our brain could constitute the basis for the self.

    Even the simplest system of cause and effect can be subject to chaos, denying us accurate predictions of its behaviour, and sometimes giving rise to astonishing structures of large-scale order. Our growing understanding of Chaos Theory is having fascinating applications in the real world - from technology to global warming, politics, human behaviour, and even gambling on the stock market. Leonard Smith shows that we all have an intuitive understanding of chaotic systems. He uses accessible maths and physics (replacing complex equations with simple examples like pendulums, railway lines, and tossing coins) to explain the theory, and points to numerous examples in philosophy and literature (Edgar Allen Poe, Chang-Tzu, Arthur Conan Doyle) that illuminate the problems. The beauty of fractal patterns and their relation to chaos, as well as the history of chaos, and its uses in the real world and implications for the philosophy of science are all discussed in this Very Short Introduction.

    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.

    During his reign he conquered the Achaemenid Persian Empire, the largest empire that had ever existed, leading his army from Greece to Pakistan, and from the Libyan desert to the steppes of Central Asia. His meteoric career, as leader of an alliance of Greek cities, Pharaoh of Egypt, and King of Persia, had a profound effect on the world he moved through. Even in his lifetime his achievements became legendary and in the centuries that following his story was told and retold throughout Europe and the East. Greek became the language of power in the Eastern Mediterranean and much of the Near East, as powerful Macedonian dynasts carved up Alexander's empire into kingdoms of their own, underlaying the flourishing Hellenistic civilization that emerged after his death.But what do we really know about Alexander? In this Very Short Introduction, Hugh Bowden goes behind the usual historical accounts of Alexander's life and career. Instead, he focuses on the evidence from Alexander's own time -- letters from officials in Afghanistan, Babylonian diaries, records from Egyptian temples -- to try and understand how Alexander appeared to those who encountered him. In doing so he also demonstrates the profound influence the legends of his life have had on our historical understanding and the controversy they continue to generate worldwide.ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area.

    Agnosticism emerges here as a much more sophisticated, and much more interesting, attitude than a simple failure to either commit to, or reject, religious belief. Le Poidevin challenges the common wisdom about agnosticism among both believers and atheists, and invites the reader to rethink their own position on the issues. Indeed, in arguing in favor of agnosticism as a respectable position to take, this stimulating and provocative guide takes issue on many points with the assertions of prominent atheists such as Richard Dawkins.

    Aristotle wrote an important treatise on it and Demosthenes remains famous to this day for his skills as a rhetorician. But skill with rhetoric today is no longer admired. Rhetoric is often seen as a synonym for shallow, deceptive language-empty words, empty rhetoric--and therefore as something quite negative. But if we view rhetoric in more neutral terms, as the art of persuasion, it is clear that we are all forced to engage with it at some level, if only because we are constantly exposed to the rhetoric of others. In this Very Short Introduction, Richard Toye explores the purpose of rhetoric. Rather than presenting a defense of it, he considers it as the foundation-stone of civil society, and an essential part of any democratic process. Using wide-ranging examples from ancient Greece, medieval Islamic preaching, the wartime speeches of Winston Churchill, and modern cinema, Toye considers why we should all have an appreciation of the art of rhetoric.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.

    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. Written by experts for the newcomer, they demonstrate the finest contemporary thinking about the central problems and issues in hundreds of key topics, from philosophy to Freud, quantum theory to Islam.

    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.

    Highlighting the historical development and continued relevance of borders, Alexander Diener and Joshua Hagen offer a powerful counterpoint to the idea of an imminent borderless world, underscoring the impact borders have on a range of issues, such as economic development, inter- and intra-state conflict, global terrorism, migration, nationalism, international law, environmental sustainability, and natural resource management. Diener and Hagen demonstrate how and why borders have been, are currently, and will undoubtedly remain hot topics across the social sciences and in the global headlines for years to come. This compact volume will appeal to a broad, interdisciplinary audience of scholars and students, including geographers, political scientists, anthropologists, sociologists, historians, international relations and law experts, as well as lay readers interested in understanding current events.
