Blundell illuminates the mysterious force of magnetism. For centuries, magnetism has been used for various purposes—through compasses it gave us the ability to navigate, and through motors, generators, and turbines, it has given us power. Blundell explores our understanding of electricity and magnetism, from the work of Galvani, Ampère, Faraday, and Tesla, and describes how Maxwell and Faraday's work led to the unification of electricity and magnetism—one of the most imaginative developments in theoretical physics. Finally, he discusses the relationship between magnetism and relativity, quantum magnetism, and its impact on computers and information storage, showing how magnetism has changed our fundamental understanding of the Universe.

    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.

    Galileo's own beautifully lucid arguments are used in this volume to show how his scientific method was utterly divorced from the Aristotelian approach to physics; it was based on a search not for causes but for laws. Galileo's methods had an overwhelming significance for the development of modern physics, and they led to a final parting of the ways between science and philosophy. Now, in this extraordinary and concise introduction, Drake provides a stimulating view of Galileo's life and works, providing a fresh perspective on Galileo's methodology and his final incrimination.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics.

    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.

    The authors introduce the general reader to some of the most important basic findings, concepts, and procedures of evolutionary biology, as it has developed since the first publications of Darwin and Wallace on the subject, over 140 years ago. They show how evolution provides a unifying set of principles for the whole of biology and sheds light on the relation of human beings to the universe and each other.

    However, their impact has not been limited to debates about geology and evolution: attempts to explain their existence has shaken religion at its very roots, and they have remained a subject of ceaseless fascination for people of all ages and backgrounds. In this readable and wide-ranging book, Keith Thomson provides a remarkably all-encompassing explanation of fossils as a phenomenon. How did Darwin use fossils to support his theory of evolution? What are living fossils? What fossils will we leave behind for future generations to examine? Beyond the scientific aspects, Thomson highlights the impact of fossils on philosophy and mythology, our concept of time, and today's popular culture. From the black market to the Piltdown Man, and from mythological dragons to living dinosaurs, fossils hold a permanent place in the popular imagination.

    In this Very Short Introduction, renowned evolutionary scholar Bernard Wood traces the history of paleoanthropology from its beginnings inthe eighteenth century to today's latest fossil finds. Along the way we are introduced to the lively cast of characters, past and present, involved in evolutionary research. Although concentrating on the fossil evidence for human evolution, the book also covers the latest genetic evidence aboutregional variations in the modern human genome that relate to our evolutionary history. Wood draws on over thirty years of experience to provide an insiders view of the field, and demonstrates that our understanding of human evolution is critically dependent on advances in related sciences such aspaleoclimatology, geochronology, systematics, genetics, and developmental biology. This is an ideal introduction for anyone interested in the origins and development of humankind.

    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.

    But how did they come to be here? What were their agricultural, spiritual, and hunting practices? How did their societies evolve and what challenges do they face today? Eminent historians Theda Perdue and Michael Green begin by describing how nomadic bands of hunter-gatherers followed the bison and woolly mammoth over the Bering land mass between Asia and what is now Alaska between 25,000 and 15,000 years ago, settling throughout North America. They describehunting practices among different tribes, how some made the gradual transition to more settled, agricultural ways of life, the role of kinship and cooperation in Native societies, their varied burial rites and spiritual practices, and many other features of Native American life. Throughout the book, Perdue and Green stress the great diversity of indigenous peoples in America, who spoke more than 400 different languages before the arrival of Europeans and whose ways of life varied according to the environments they settled in and adapted to so successfully. Most importantly, the authors stresshow Native Americans have struggled to maintain their sovereignty--first with European powers and then with the United States--in order to retain their lands, govern themselves, support their people, and pursue practices that have made their lives meaningful. Going beyond the stereotypes that so often distort our views of Native Americans, this Very Short Introduction offers a historically accurate, deeply engaging, and often inspiring account of the wide array of Native peoples in America.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics.

    But as Morris Rossabi reveals in this VeryShort Introduction, within two generations of their bloody conquests, the Mongols evolved from conquerors and predators to wise rulers who devised policies to foster the economies of the lands they had subjugated. By adopting political and economic institutions familiar to the local populations andrecruiting native officials, they won over many of their non-Mongol subjects. In addition, Mongol nobles were ardent patrons of art and culture, supporting the production of Chinese porcelains and textiles, Iranian tiles and illustrated manuscripts, and Russian metalwork. Perhaps most important, thepeace imposed by the Mongols on much of Asia and their promotion of trade resulted in considerable interaction among merchants, scientists, artists, and missionaries of different ethnic groups--including Europeans. Modern Eurasian and perhaps global history starts with the Mongol empire.

    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?

    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.

    Readers meet a people highly skilled in sculpture, astronomy, city planning, poetry, and philosophy, who were also profoundly committed tocosmic regeneration through the thrust of the ceremonial knife and through warfare. Dav�d Carrasco looks beyond Spanish accounts that have colored much of the Western narrative to let Aztec voices speak about their origin stories, the cosmic significance of their capital city, their methods of childrearing, and the contributions women made to daily life and the empire. Carrasco discusses the arrival of the Spaniards, contrasts Aztec mythical traditions about the origins of their city with actual urban life in Mesoamerica, and outlines the rise of the Aztec empire. He also explores Aztecreligion, which provided both justification for and alternatives to warfare, sacrifice, and imperialism, and he sheds light on Aztec poetry, philosophy, painting, and especially monumental sculpture and architecture. He concludes by looking at how the Aztecs have been portrayed in Western thought, art, film, and literature as well as in Latino culture and arts.

    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.
