In this Very Short Introduction, Peter M. Higgins, a renowned popular-science writer, unravels the world of numbers, demonstrating its richness and providing an overview of all the number types that feature in modern science and mathematics. Indeed, Higgins paints a crystal-clear picture of the number world, showing how the modern number system matured over many centuries, and introducing key concepts such as integers, fractions, real and imaginary numbers, and complex numbers. Higgins sheds light on such fascinating topics as the series of primes, describing how primes are now used to encrypt confidential data on the internet. He also explores the infinite nature of number collections and explains how the so-called real numbers knit together to form the continuum of the number line. Written in the fashion of Higgins' highly popular science paperbacks, Numbers accurately explains the nature of numbers and how so-called complex numbers and number systems are used in calculations that arise in real problems.

    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.

    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.

    Without it, there would be no science or technology. There would be no moral responsibility either, as none of our thoughts would be connected with our actions and none of our actions with any consequences. Nor would we have a system of law because blame resides only in someone having caused injury or damage.Any intervention we make in the world around us is premised on there being causal connections that are, to a degree, predictable. It is causation that is at the basis of prediction and also explanation. This Very Short Introduction introduces the key theories of causation and also the surrounding debates and controversies.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.

    Indeed, no other legislature in the world approaches its power. Yet most Americans have only a murky idea of how it works. In The U.S. Congress, Donald A. Ritchie, a congressional historian for more than thirty years, takes readers on a fascinating, behind-the-scenes tour of Capitol Hill--pointing out the key players, explaining their behavior, and translating parliamentary language into plain English. No mere civics lesson, this eye-opening book provides an insiders perspective on Congress, matched with a professional historians analytical insight. After a swift survey of the creation of Congress by the constitutional convention, he begins to unscrew the nuts and pull out the bolts. What is it like to campaign for congress? To attract large donors? To enter either house with no seniority? He answers these questions and more, explaining committee assignments (and committee work), the role of staffers and lobbyists, floor proceedings, parliamentary rules, and coalition building. Ritchie explores the great effort put into constituent service--as representatives and senators respond to requests from groups and individuals--as well as media relations and news coverage. He also explores how the grand concepts we all know from civics class--checks and balances, advise and consent, congressional oversight--work in practice, in an age of strong presidents and a muscular Senate minority (no matter which party is in that position). In this sparkling addition to Oxfords Very Short Introduction series, Donald Ritchie moves beyond the cynicism and the platitudes to provide a gem of a portrait of how Congress really works.

    But when did this essential part of our lives begin? Why do we all write differently and how did writing evolve into what we use today? All of these questions are answered in this Very Short Introduction. Andrew Robinson tells the fascinating story of the history of writing, shedding light on its development and examining the enormous variety of writing and scripts we use today. Starting with the origins of writing five thousand years ago, with cuneiform and Egyptian hieroglyphs, Robinson explains how these early forms developed into hundreds of scripts, including the Roman alphabet and Chinese characters. He reveals how the modern writing symbols and abbreviations we take for granted today--including airport signage and text messaging--resemble ancient ones much more closely than we might think. The book also includes a chronology of events from 3300 BC to AD 2000, a list of titles for further reading, and an index.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics.

    Modern Art: A Very Short Introduction engages general readers, offering them not only information and ideas about modern art, but also explaining its contemporary relevance and history. The book focuses on interrogating the idea of modern art by asking such questions as: What makes a work of art qualify as modern, or fail to? How has this selection been made? What is the relationship between modern and contemporary art? Is postmodernist art no longer modern, or just no longer modernist? In either case, why--and what does this claim mean, both for art and the idea of the modern?Cottingham examines many key aspects of this subject, including the issue of controversy in modern art, from Manet's Dejeuner sur L'Herbe (1863) to Picasso's Les Demoiselles, and Tracey Emin's Bed (1999).

    In The Blues, Wald surveys a genre at the heart of American culture.It is not an easy thing to pin down. As Howlin' Wolf once described it, "When you ain't got no money and can't pay your house rent and can't buy you no food, you've damn sure got the blues." It has been defined by lyrical structure, or as a progression of chords, or as a set of practices reflecting West African "tonal and rhythmic approaches," using a five-note "blues scale." Wald sees blues less as a style than as a broad musical tradition within a constantly evolving pop culture. He traces its roots in work and praise songs, and shows how it was transformed by such professional performers as W. C. Handy, who first popularized the blues a century ago. He follows its evolution from Ma Rainey and Bessie Smith through Bob Dylan and Jimi Hendrix; identifies the impact of rural field recordings of Blind Lemon Jefferson, Charley Patton and others; explores the role of blues in the development of both country music and jazz; and looks at the popular rhythm and blues trends of the 1940s and 1950s, from the uptown West Coast style of T-Bone Walker to the "down home" Chicago sound of Muddy Waters. Wald brings the story up to the present, touching on the effects of blues on American poetry, and its connection to modern styles such as rap.As with all of Oxford's Very Short Introductions, The Blues tells you--with insight, clarity, and wit--everything you need to know to understand this quintessentially American musical genre.

    It is a word with which we are universally familiar, and a condition that haunts the human imagination. In this Very Short Introduction, Andrew Scull provides a provocative and entertaining examination of the social, cultural, medical, and artistic responses to mental disturbance across more than two millennia, concluding with some observations on the contemporary accounts of mental illness. He shows that through the centuries, in poetry and in prose, in drama and in the visual arts, madness has been on display for all to see. He also describes how a whole industry has grown up, devoted to its management and suppression. Perhaps most important, he conveys how madness profoundly disturbs our common sense assumptions; threatens the social order, both symbolically and practically; creates almost unbearable disruptions in the texture of daily living; and turns our experience and our expectations upside down. Throughout this fascinating history, many fascinating and arresting pictures illuminate the overall portrait of madness in its various contexts.

    This insight raises big questions about the nature of music and the nature of humankind, and ethnomusicologists argue that to properly address these questions, we must study music in all its geographical and historical diversity.In this Very Short Introduction, one of the foremost ethnomusicologists, Timothy Rice, offers a compact and illuminating account of this growing discipline, showing how modern researchers go about studying music from around the world, looking for insights into both music and humanity. The reader discovers that ethnomusicologists today not only examine traditional forms of music-such as Japanese gagaku, Bulgarian folk music, Javanese gamelan, or Native American drumming and singing-but also explore more contemporary musical forms, from rap and reggae to Tex-Mex, Serbian turbofolk, and even the piped-in music at the Mall of America. To investigate these diverse musical forms, Rice shows, ethnomusicologists typically live in a community, participate in and observe and record musical events, interview the musicians, their patrons, and the audience, and learn to sing, play, and dance. It's important to establish rapport with musicians and community members, and obtain the permission of those they will work with closely over the course of many months and years. We see how the researcher analyzes the data to understand how a particular musical tradition works, what is distinctive about it, and how it bears the personal, social, and cultural meanings attributed to it. Rice also discusses how researchers may apply theories from anthropology and other social sciences, to shed further light on the nature of music as a human behavior and cultural practice.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.

    Yet there is much more to the debate than theclash of these extremes. As Thomas Dixon shows in this balanced and thought-provoking introduction, a whole range of views, subtle arguments, and fascinating perspectives can be found on this complex and centuries-old subject. He explores the key philosophical questions that underlie the debate, but also highlights the social, political, and ethical contexts that have made the tensions between science and religion such a fraught and interesting topic in the modern world. Dixon emphasizes how the modern conflict between evolution and creationism is quintessentially an American phenomenon, arising from the culture and history of the United States, as exemplified through the ongoing debates about how to interpret the First-Amendment's separation of church and state. Along the way, he examines landmark historical episodes such as the Galileo affair, Charles Darwin's own religious andscientific odyssey, the Scopes Monkey Trial in Tennessee in 1925, and the Dover Area School Board case of 2005, and includes perspectives from non-Christian religions and examples from across the physical, biological, and social 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.
