A criminal case can often hinge on a piece of evidence such as a hair, a blood trace, a bit of saliva on a cigarette butt, or the telltale mark of a tire tread. High profile cases have stoked this interest in recent years and some of the most popular shows on television--such as CSI: Crime Scene Investigation and its raft of spin-offs--attest to the enduring popularity of forensic science as a form of grisly entertainment. This Very Short Introduction looks at the nature of forensic science, examining what forensic science is, how it is used in the investigation of crime, how crime scenes are managed, how forensic scientists work, the different techniques used to recover evidence, and the range of methods available for analysis. It also considers how forensic science serves the criminal justice system and the challenges of communicating complex scientific evidence in a court of law.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.

    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.

    In this Very Short Introduction, engineer David Muir Wood turns a spotlight on a field that we often take for granted. He sheds light on the nature and importance of civil engineering in the history of civilization and urbanization, outlines its many accomplishments in the modern era, and points to the hurdles that civil engineering will face in the future. Beginning with the task of creating a settlement on a deserted island, Muir Wood sets out the problems that civil engineers face every day, highlighting the social and environmental challenges as well as the grasp of science and technology needed to craft buildings, bridges, tunnels, houses, and areas of recreation. The author also profiles the lives of some of the major civil engineers, such as Isambard Kingdom Brunel, the acclaimed builder of steamships, railways, and tunnels, and Sir Joseph Bazalgette, whose sewer system in central London was instrumental in relieving the city from cholera epidemics. Finally, Muir Wood considers the growing difficulty of managing our water and energy supplies, and he looks at the engineering profession's increased sensitivity to building and the environment.

    As of 2004 an estimated 40 million people were living with the disease, and about 20 million had died. Despite rapid scientific advances there is still no cure and the drugs are expensive and toxic. In the developing world, especially in parts of Africa, life expectancy has plummeted to below 35 years, causing a serious decline in economic growth, a sharp increase in orphans, and the imminent collapse of health care systems. The news is not all bleak though. There have been unprecedented breakthroughs in understanding diseases and developing drugs. Because the disease is so closely linked to sexual activity and drug use, the need to understand and change behavior has caused us to reassess what it means to be human and how we should operate in the globalizing world. This Very Short Introduction tackles the science, the international and local politics, the fascinating demographics, and the devastating consequences of the disease, and suggests how we must respond.About the Series: Oxford's Very Short Introductions offers concise and original introductions to a wide range of subjects--from Islam to Sociology, Politics to Classics, and Literary Theory to History.

    Considering the remarkable achievements chemistry has made, he presents a fascinating, clear, and rigorous exploration of the world of chemistry - its structure, core concepts, and contributions to the material comfort and culture of the modern world.

    Robots have taken their first steps into homes and hospitals, and have seen spectacular success in planetary exploration. Yet despite these successes, robots have failed to live up to the predictions of the 1950s and 60s, when it was widely thought--by scientists as well as the public--that we would have, by now, intelligent robots as butlers, companions, or co-workers. This Very Short Introduction explains how it is that robotics can be both a success story and a disappointment, and how robots can be both ordinary and remarkable. Alan Winfield introduces the subject by looking at the parts that together make a robot. Not surprisingly, these parts each have a biological equivalent: a robot's camera is like an animal's eyes, a robot's microcomputer is equivalent to an animal's brain, and so on. By introducing robots in this way this book builds a conceptual, non-technical picture of what a robot is, how it works, and how "intelligent" it is.

    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.

    Politicians of all stripes stress its importance, as do church leaders, captains of industry and every kind of campaigning group--from those supporting global causes, such as tackling world poverty, to others with a largely local focus, such as combating neighborhood crime. In this brilliant, compact introduction, Richard Bellamy offers an eye-opening look at an idea that is as important as it is rare--the prospect of influencing government policy according to reasonably fair rules and on a more or less equal basis with others. Bringing together the most recent scholarship, the book sheds light on how ideas of citizenship have changed through time from ancient Greece to the present, looks at concepts such as membership and belonging, and highlights the relation between citizenship, rights, and democracy. Bellamy also examines the challenges confronting the very possibility of citizenship today, the impact of globalization, the desirability of "global citizenship," the teaching of citizenship in schools, citizenship tests for immigrants, and the many different definitions and types of citizenship in modern society.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics.

    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.

    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.

    Revealing the intriguing and challenging nature of legal philosophy with clarity and enthusiasm, Raymond Wacks explores the notion of law and its role in our lives. Referring to key thinkers from the classical world to the modern, he looks at the central questions behind legal theory that have always fascinated lawyers and philosophers, as well as anyone who ever wondered about law's relation to justice, morality, and democracy.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 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.

    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.

    Newspaper column inches have been devoted to murderers with psychopathic features, and we also encounter psychopaths in films and books. Individuals with psychopathy are characterised in particular by lack of empathy and guilt, manipulation of other people and, in the case of criminal psychopathy, premeditated violent behaviour. They are dangerous and can incur immeasurable emotional, psychological, physical, and financial costs to their victims and their families.Despite the public fascination with psychopathy, there is often a very limited understanding of the condition, and several myths about psychopathy abound. For example, people commonly assume that all psychopaths are sadistic serial killers or that all violent and antisocial individuals are psychopaths. Yet, research shows that most psychopaths are not serial killers, and, equally, there are plenty of antisocial and violent offenders who are not psychopaths. This Very Short Introduction gives an overview of how we can identify individuals with or at risk of developing psychopathy, and how they differ from other people who display antisocial behavior. Essi Viding also explores the latest genetic, neuroscience, and psychology evidence in order to illuminate why psychopaths behave and develop the way they do, and considers whether it is possible to prevent or even treat psychopathy.ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area.

    In this Very Short Introduction, Thomas Forrest Kelly provides not only a compact overview of the music itself, but also a lively look at the many attempts over the last two centuries to revive it. Kelly shows that the early-music revival has long been grounded in the idea of spontaneity, of excitement, and of recapturing experiences otherwise lost to us--either the rediscovery of little-known repertories or the recovery of lost performing styles, with the conviction that, with the right performance, the music will come to life anew. Blending musical and social history, he shows how the Early Music movement in the 1960s took on political overtones, fueled by a rebellion against received wisdom and enforced conformity. Kelly also discusses ongoing debates about authenticity, the desirability of period instruments, and the relationship of mainstream opera companies and symphony orchestras to music that they often ignore, or play in modern fashion.
