The book describes dramatic breakthroughs in our knowledge of how sleep occurs, what it does, and what happens to our health if we do not have enough. The authors consider the impact of modern society, examining the relationship between sleep and our 24/7 culture.

    It is an area that continues to attract and fascinate many people, even though it is generally thought to be highly complex and abstract. For some it is associated with the mystical or religious. For others it is known through the metaphysical poets who talk of love and spirituality. This Very Short Introduction goes right to the heart of the matter, getting to the basic and most important questions of metaphysical thought in order to understand the theory: What are objects? Do colors and shapes have some form of independent existence? Is the whole just a sum of the parts? What is it for one thing to cause another rather than just being associated with it? What is possible? Does time pass? By using simple questions to initiate thought about the basic issues around substance, properties, changes, causes, possibilities, time, personal identity, nothingness, and consciousness, Stephen Mumford provides a clear and down-to-earth path through this analytical tradition at the core of philosophical thought.

    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.

    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.

    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.

    And while research into cancer is bringing huge improvements in the range of options available to cancer patients, these new therapies bring with them massive challenges for healthcare systems struggling to find the huge sums of money for the large numbers of patients involved. This Very Short Introduction explores the facts underlying these figures, starting with the basic facts about the disease before moving on to the bigger picture of the economics and politics of cancer care. Nick James, founder of the CancerHelp UK website, examines the trends in diagnosis of the disease and the constant improvements in treatment techniques that result in better cure rates and increased quality and quantity of life for cancer patients. The book also considers issues surrounding expensive drug development, highlights what can be done to reduce the risk of developing cancer, and discusses the use of complementary and alternative therapies.

    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.

    But despite the many measures taken to overhaul the educational system, student math and reading scores rarely seem to improve. Taking the reader from the schools of ancient times to the present day, this Very Short Introduction explains why education has followed the path that it has taken-and what we might do to improve it. Education expert Gary Thomas delves into some of the big questions of education and the twists and turns the field has taken over time, looks at the work of such key thinkers as Piaget and Vygotsky, and examines such recent innovations as the introduction of progressive education in the 20th century and the marketization of schools over the last few decades. Thomas repeatedly returns to the question of why education has recently become so test-orientated and he explores the consequences of this obsession with testing for children. He also looks at moves that teachers and policy-makers have made to try to improve what goes on in schools, from changing teaching so that it mirrors the way children learn, to making schools more inclusive and meaningful for a broader range of students.

    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.

    The book discusses environmental issues including pollution control, reducing environmental damage, global climate change policies, questions about how we should balance environmental and economic considerations, and what form government policies should take. In recent years, Smith reveals, many economists have argued for greater use of incentives such as pollution charges and emissions trading rather than more traditional direct regulation of polluters. Including many illustrative case studies, this book offers an illuminating introduction to an exciting field of economics.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics.

    They haunt us, we cherish them, and in our lives we collect more of them with each new experience. Without memory, you would not be able to maintain a relationship, drive your car, talk to your children, read a poem, watch television, or do much ofanything at all. Memory: A Very Short Introduction explores the fascinating intricacies of human memory. Is it one thing or many? Why does it seem to work well sometimes and not others? What happens when it goes wrong? Can it be improved or manipulated through techniques such as mnemonic rhymes orbrain implants? How does memory change as we age? And what about so-called recovered memories--can they be relied upon as a record of what actually happened in our personal past? This book brings together our most recent knowledge to address (in a scientifically rigorous but highly accessible way)these and many other important questions about how memory works, and why we can't live without it.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics.

    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.

    This Very Short Introduction, addresses a variety of questions, including what a black hole actually is, how they are characterized and discovered, and what would happen if you came too close to one. Professor Katherine Blundell looks at the seemingly paradoxical, mysterious, and intriguing phenomena of black holes. Outlining their nature and characteristics, both those resulting from the spectacular collapse of heavy stars, and the giant black holes found at the centres of galaxies, she separates scientific fact from science fiction, and demonstrates the important role they play in the cosmos.

    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.
