It contains more than 99% of the world's living space, produces half of its oxygen, plays a critical role in regulating its climate, and supports a remarkably diverse and exquisitely adapted array of life forms, from microscopic viruses, bacteria, and plankton to the largest existing animals. In this unique Very Short Introduction, biologist Philip Mladenov provides a comprehensive overview of marine biology, offering a tour of marine life and marine processes that ranges from the polar oceans to tropical coral reefs, and from shoreline mollusks to deep-sea hydrothermal vents. Mladenov also looks at a number of factors that pose a significant threat to the marine environment and to many of its life forms-threats such as overfishing, coastal development, plastic pollution, oil spills, nutrient pollution, the spread of exotic species, and the emission of climate changing greenhouse gases. Throughout the book he successfully weaves around the principles of marine biology a discussion of the human impacts on the oceans and the threats these pose to our welfare.

    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.

    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.

    The fruits of geology provide most of the materials that give us shelter, and most of the energy that drives our modern lives. Within the study of geology lie some of the clues to the extraordinary impact our species is going to play out on the planet, in centuries and millennia to come.In this Very Short Introduction Jan Zalasiewicz gives a brief introduction to the fascinating field of geology. Describing how the science developed from its early beginnings, he looks at some of the key discoveries that have transformed it, before delving into its various subfields, such as sedimentology, tectonics, and stratigraphy. Analyzing the geological foundations of the Earth, Zalasiewicz explains the interlocking studies of tectonics, geophysics, and igneous and metamorphic petrology and geochemistry; and describes how rocks are dated by radiometric dating. Considering the role and importance of geology in the finding and exploitation of resources (including fracking), he also discusses its place in environmental issues, such as foundations for urban structures and sites for landfill, and in tackling issues associated with climate change. Zalasiewicz concludes by discussing the exciting future and frontiers of the field, such as the exploration of the geology of Mars.ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area.

    After meeting with Americans on extensive travels in the United States, and intense study of documents and authorities, he authored the landmark Democracy in America, publishing its two volumes in 1835 and 1840. Ever since, this book has been the best source for every serious attempt to understand America and democracy itself. Yet Tocqueville himself remains a mystery behind the elegance of his style. Now one of our leading authorities on Tocqueville explains him in this splendid new entry in Oxford's acclaimed Very Short Introduction series. Harvey Mansfield addresses his subject as a thinker, clearly and incisively exploring Tocqueville's writings--not only his masterpiece, but also his secret Recollections, intended for posterity alone, and his unfinished work on his native France, The Old Regime and the Revolution. Tocqueville was a liberal, Mansfield writes, but not of the usual sort. The many elements of his life found expression in his thought: his aristocratic ancestry, his ventures in politics, his voyages abroad, his hopes and fears for America, and his disappointment with France. All his writings show a passion for political liberty and insistence on human greatness. Perhaps most important, he saw liberty not in theories, but in the practice of self-government in America. Ever an opponent of abstraction, he offered an analysis that forces us to consider what we actually do in our politics--suggesting that theory itself may be an enemy of freedom. And that, Mansfield writes, makes him a vitally important thinker for today. Translator of an authoritative edition of Democracy in America, Harvey Mansfield here offers the fruit of decades of research and reflection in a clear, insightful, and marvelously compact introduction.

    Every technology we rely on today was created by the human mind, seeking to understand the universe around us. Scientific knowledge is our most precious possession, and our future will be shaped by the breakthroughs to come. In this personal and fascinating work, Neil Turok, Director of the Perimeter Institute for Theoretical Physics, explores the transformative scientific discoveries of the past three centuries -- from classical mechanics, to the nature of light, to the bizarre world of the quantum, and the evolution of the cosmos. Each new discovery has, over time, yielded new technologies causing paradigm shifts in the organization of society. Now, he argues, we are on the cusp of another major transformation: the coming quantum revolution that will supplant our current, dissatisfying digital age. Facing this brave new world, Turok calls for creatively re-inventing the way advanced knowledge is developed and shared, and opening access to the vast, untapped pools of intellectual talent in the developing world. Scientific research, training, and outreach are vital to our future economy, as well as powerful forces for peaceful global progress.

    But defining happiness can be difficult. In this Very Short Introduction, Dan Haybron considers the true nature of happiness. By examining what it is, assessing its subjective values, its importance in our lives, and how we can (and should) pursue it, he considers the current thinking on happiness, from psychology to philosophy. Illustrating the diverse routes to happiness, Haybron reflects on the growing influence of secular Western ideas in the contemporary pursuit of a good life, and considers the influence of social context on our satisfaction and well-being.

    In a short and unhappy life, he wrote many books and articles on literary, satirical, religious and psychological themes, but the diversity and idiosyncratic style of his writing have contributed to a misunderstanding of his ideas. In this book--the only introduction to the full range of Kierkegaard's thought--Patrick Gardiner demonstrates how Kierkegaard developed his ideas and examines his thoughts in light of the doctrines on society developed by his contemporaries Marx and Feuerbach. Finally, he assesses the profound importance of Kierkegaard's ideas on the development of modern ways of thinking.

    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.
