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.

    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.

    But how can it be defined? In this highly readable introduction the mysteries of this most elusive of concepts are unraveled, casting a critical light upon the way we live now, from the politicizing of museumculture to the cult of the politically correct. The key postmodernist ideas are explored and challenged, as they figure in the theory, philosophy, politics, ethics and artwork of the period, and it is shown how they have interacted within a postmodernist culture.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 examines a distinctive stage in the development of capitalism that began in the 1980s, in order to understand where we are now and how capitalism has evolved since. The book discusses the crisis tendencies of capitalism--including the S.E. Asian banking crisis, the collapse of the Russian economy, and the 1997-1998 global financial crisis--asking whether capitalism is doomed to fail. In the end, the author ruminates on a possible alternative to capitalism, discussing socialism, communal and cooperative experiments, and alternatives proposed by environmentalists.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics.

    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.

    Bill Gates. George W. Bush. Osama bin Laden. Leaders and leadership are perennial topics of debate. What is leadership? How does one become a leader? Do we actually need leaders? In this Very Short Introduction, Keith Grint offers provocative answers to these questions, prompting readers to rethink their assumptions about what leadership is. Indeed, Grint argues that leadership is a very elusive quality, and that there are few definitive answers to be found, which explains why most books on leadership produce so much heat and so little light. But there are important questions to ask, questions which shed light on why leadership so resists definition. Grint looks at the way leadership has evolved from its earliest manifestations in ancient societies, highlights the early ideas about leadership found in Plato, Sun Tzu, Machiavelli and others, considers how social, economic, and political forces can undermine particular modes of leadership, and discusses the practice of management, its history, future, and influence on all aspects of society.

    This fascinating Very Short Introduction discusses all the aspects of psychology that are relevant to the legal and criminal process as a whole. It includes explanations of criminal behavior and criminality, including the role of mental disorder in crime, and it reveals how forensic psychology contributes to helping investigate the crime and catching the perpetrators. David Canter also explains how psychologists provide guidance to all those involved in civil and criminal court proceedings, including both the police and the accused, and what expert testimony can be provided by a psychologist about the offender at the trial. Finally, Canter describes how forensic psychology is used, particularly in prisons, to help in the management, treatment and rehabilitation of offenders, once they have been convicted.

    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.

    And considering that the "one man" is Neal Stephenson, "the hacker Hemingway" (Newsweek) -- acclaimed novelist, pragmatist, seer, nerd-friendly philosopher, and nationally bestselling author of groundbreaking literary works (Snow Crash, Cryptonomicon, etc., etc.) -- the word is well worth hearing. Mostly well-reasoned examination and partial rant, Stephenson's In the Beginning... was the Command Line is a thoughtful, irreverent, hilarious treatise on the cyber-culture past and present; on operating system tyrannies and downloaded popular revolutions; on the Internet, Disney World, Big Bangs, not to mention the meaning of life itself.

    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.

    But why did it last so long? And what impact did it have on the United States, the Soviet Union, Europe, and the Third World? Finally, how did it affect the broader history of the second half of the twentieth century--what were the human and financial costs? This Very Short Introduction provides a clear and stimulating interpretive overview of the Cold War, one that will both invite debate and encourage deeper investigation.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics.

    In this Very Short Introduction, Michael Newman seeks to place the idea of socialism in a modern context for today's readers. He explains socialist ideas in the framework of its historical evolution, from the French Revolution to the present day, and examines practical attempts to implement socialism.Not just another history of socialist ideas, this book aims for a different approach that looks at practice as well as theory--centering on the contrast between Communism and Social Democracy. The relationship between socialism and notions of democracy, freedom, and equality is also discussed. Newman brings the subject entirely up to date by tackling contemporary forms of socialism. While the book's focus is on Europe and the Soviet Union, it is set in a broader geographical context. Newman's fresh approach to the subject enables the reader to re-evaluate socialism.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics.

    Negotiations for the accession of six new states have begun, and membership, which already covers almost all of Western Europe, will soon extend to most of Central and Eastern Europe. The Union's institutions have been reformed, and its powers may soon reach beyond the economy and the environment into the fields of foreign policy and defense. This thorough yet succinct introduction has been completely updated to take the many recent developments into account. John Pinder provides a detailed and coherent view of the evolution of the European Union, and investigates its future as Europe thrives in the new millennium.

    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.

    It is a ‘ must’ book for those in every branch of science . . . in addition, economists, politicians, statesmen, and businessmen cannot afford to overlook cybernetics and its tremendous, even terrifying implications. "It is a beautifully written book, lucid, direct, and despite its complexity, as readable by the layman as the trained scientist." -- John B. Thurston, "The Saturday Review of Literature" Acclaimed one of the "seminal books . . . comparable in ultimate importance to . . . Galileo or Malthus or Rousseau or Mill," "Cybernetics" was judged by twenty-seven historians, economists, educators, and philosophers to be one of those books published during the "past four decades", which may have a substantial impact on public thought and action in the years ahead." -- Saturday Review
