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.

    It is impossible to understand the spread of an epidemic, a computer virus, large-scale blackouts, or massive extinctions without taking into account the network structure that underlies all these phenomena. In this Very Short Introduction, Guido Caldarelli and Michele Catanzaro discuss the nature and variety of networks, using everyday examples from society, technology, nature, and history to explain and understand the science of network theory. They show the ubiquitous role of networks; how networks self-organize; why the rich get richer; and how networks can spontaneously collapse. They conclude by highlighting how the findings of complex network theory have very wide and important applications in genetics, ecology, communications, economics, and sociology.

    It requires, in short, an understanding of probability. In this Very Short Introduction, John Haigh introduces the ideas of probability--and the different philosophical approaches to probability--and gives a brief account of the history of development of probability theory, from Galileo and Pascal to Bayes, Laplace, Poisson, and Markov. He describes the basic probability distributions and discusses a wide range of applications in science, economics, and a variety of other contexts such as games and betting. He concludes with an intriguing discussion of coincidences and some curious paradoxes.

    It avoids the traditional style-spotting approach and instead gives us an idea of what it is about buildings that moves us, and what it is that makes them important artistically and culturally. The book begins by looking at how architecture acquires meaning through tradition, and concludes with the exoticism of the recent avant-garde period. Illustrations of particular buildings help to anchor the general points with specific examples, from ancient Egypt to the present day.

    Yet, the science underpinning this technology is less visible and little understood outside the professional computer science community. As a scientific discipline, computer science stands alongside the likes of molecular biology and cognitive science as one of the most significant new sciences of the post Second World War era.In this Very Short Introduction, Subrata Dasgupta sheds light on these lesser known areas and considers the conceptual basis of computer science. Discussing algorithms, programming, and sequential and parallel processing, he considers emerging modern ideas such as biological computing and cognitive modelling, challenging the idea of computer science as a science of the artificial.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, leading authority Jonathan Slack offers a clear and informative overview of stem cells--what they are, what scientists do with them, what stem cell therapies are available today, and how they might be used in the future. Slack explains the difference between embryonic stem cells, which exist only in laboratory cultures, and tissue-specific stem cells, which exist in our bodies, and he discusses how embryonic stem cells may be used in the future to treat such illnesses as diabetes, Parkinson's disease, heart disease, spinal trauma, and retinal degeneration. But he stresses that, despite important advances, the clinical applications of stem cells are still in their infancy and that most real stem cell therapy today is some form of bone marrow transplantation. Slack concludes by analyzing how medical innovation has occurred in this area in recent years and he draws out some of the lessons for the development of new therapies in the future.

    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.

    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.

    They are the oldest forms of life and the most prolific of all living organisms, inhabiting every part of the Earth's surface, its ocean depths, and even such inhospitable places as boiling hot springs. In this Very Short Introduction, bacteriologist Sebastian Amyes explores the nature of bacteria, their origin and evolution, bacteria in the environment, and bacteria and disease. Amyes discusses some of the major infections caused by bacteria-bacteria causes pneumonia, diphtheria, cholera, and many other diseases-and shows how these pathogens avoid the defences of the human body. But the book looks at all aspects of bacteria, not just the negative side, stressing the key benefits of bacteria, which have been harnessed to preserve food, dispose of waste and to provide compost for horticulture. Indeed, life for man and for many animals would be impossible without bacteria. Amyes also offers a glance into the future, describing how bacteria might be manipulated to perform tasks that they previous were unable to perform and discussing the recent construction of a completely synthetic bacterial cell.

    In this lively and compact introduction, astrophysicist Andrew King reveals how the laws of physics force stars to evolve, driving them through successive stages of maturity before their inevitable and sometimes spectacular deaths, to end as remnants such as black holes. The book shows how we know what stars are made of, how gravity forces stars like the Sun to shine by transmuting hydrogen into helium in their centers, and why this stage is so long-lived and stable. Eventually the star ends its life in one of just three ways, and much of its enriched chemical content is blasted into space in its death throes. Every dead star is far smaller and denser than when it began, and we see how astronomers can detect these stellar corpses as pulsars and black holes and other exotic objects. King also shows how astronomers now use stars to measure properties of the Universe, such as its expansion. Finally, the book asks how it is that stars form in the first place, and how they re-form out of the debris left by stars already dead. These birth events must also be what made planets, not only in our solar system, but around a large fraction of all stars.

    Once access to the Internet became a reality for large swathes of the world's population, the amount of data generated each day became huge, and continues to grow exponentially. It includes all our uploaded documents, video, and photos, all our social media traffic, our online shopping, even the GPS data from our cars."Big Data" represents a qualitative change, not simply a quantitative one. The term refers both to the new technologies involved, and to the way it can be used by business and government. Dawn E. Holmes uses a variety of case studies to explain how data is stored, analyzed, and exploited by a variety of bodies from big companies to organizations concerned with disease control. Big data is transforming the way businesses operate, and the way medical research can be carried out. At the same time, it raises important ethical issues; Holmes discusses cases such as the Snowden affair, data security, and domestic smart devices which can be hijacked by hackers.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, Michael Wood offers a wealth of insight into the nature of film, considering its role and impact on society as well as its future in the digital age. As Wood notes, film is many things, but it has become above all a means of telling stories through images and sounds. The stories are often quite false, frankly and beautifully fantastic, and they are sometimes insistently said to be true. Indeed, many condemn movies as an instrument of illusion, an emphatic way of seeing what is not there. And others celebrate the reverse: that film brings us closest to the world as it actually is. "Photography is truth," a character says in a film by Jean-Luc Godard. "And cinema is the truth twenty-four times per second." But they are stories in either case, and there are very few films, Wood observes, even in avant-garde art, that don't imply or quietly slip into narrative.

    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.
