This Very Short Introduction presents a succinct guide to the key episodes in that story - from the very origins of life four million years ago to the extraordinary diversity of species around the globe today.Beginning with an explanation of the controversies surrounding the birth of life itself, each following chapter tells of a major breakthrough that made new forms of life possible: including sex and multicellularity, hard skeletons, and the move to land. Along the way, we witness the greatest mass extinction, the first forests, the rise of modern ecosystems, and, most recently, conscious humans.Introducing ideas from a range of scientific disciplines, from evolutionary biology and earth history, to geochemistry, palaeontology, and systematics, Michael Benton explains how modern science pieces the evidence in this vast evolutionary puzzle together, to build up an accessible and up-to-date picture of the key developments in the history of life on earth.

    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.

    It explains what algorithms do, how they are used, the risks associated with using them, and why governments should be concerned. Important areas arehighlighted, such as Stream Ciphers, block ciphers, public key algorithms, digital signatures, and applications such as e-commerce. This book highlights the explosive impact of cryptography on modern society, with, for example, the evolution of the internet and the introduction of more sophisticatedbanking methods.

    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.

    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.

    Taking a thematic rather than strictly chronological approach, W.F. Bynum, explores the key turning points in the history of Western medicine-such as the first surgical procedures, the advent of hospitals, the introduction of anesthesia, X-Rays, vaccinations, and many other innovations, as well as the rise of experimental medicine. The book also explores Western medicine's encounters with Chinese and Indian medicine, as well as nontraditional treatments such as homeopathy, chiropractic, and other alternative medicines. Covering a vast amount of information, this Very Short Introduction sheds new light on medicine's past, while at the same time engaging with contemporary issues, discoveries, and controversies, such as the spiraling costs of health care, lack of health insurance for millions, breakthrough treatments, and much more. For readers who wish to understand the how we have arrived at our current state of medical practice and knowledge, this book is essential reading.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics.

    The most fundamental differences are philosophical, and readers of this book will emerge with a clearer understandingof paradoxical-sounding concepts such as infinity, curved space, and imaginary numbers. The first few chapters are about general aspects of mathematical thought. These are followed by discussions of more specific topics, and the book closes with a chapter answering common sociological questionsabout the mathematical community (such as Is it true that mathematicians burn out at the age of 25?) It is the ideal introduction for anyone who wishes to deepen their understanding of mathematics.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 1800 it was overwhelmingly rural, agrarian, multilingual, and almost half-Celtic. A century later it was largely urban and English. The effects of the Industrial Revolution caused cities to swell enormously. London, for example, grew from about 1 million people to over 6 million. Abroad, the British Empire was reaching its apex, while at home the world came to marvel at the Great Exhibition of 1851 with its crowning achievement--the Crystal Palace. Historians Christopher Harvie and Colin Matthew present a comprehensive and authoritative guide to the social, economic, and political events that marked the era on which many believed the sun would never set.

    But how much do these types of entertainment really tell us about recent scientific discoveries and the latest research into the world of the dinosaur?This is the first book explain how scientists have been able to put together a picture of how dinosaurs looked, what they ate, and how they moved and interacted with each other. Taking a new approach to the subject, David Norman combines different areas of science, such as anatomy, genetics, forensics, and engineering design, to piece together the latest evidence of how animal life evolved on earth. Norman engagingly lays out the history of dinosaur research, from the speculation over ancient myths about dragons, to the latest virtual reality animation sequences and engineering design analysis. He also discusses the role that informed speculation and luck has played in many of the major discoveries.This book is a fantastic introduction for those just beginning to take an interest in dinosaurs and a must-read for true dinosaur-lovers who want to know not just the latest theories and discoveries, but how scientists achieved them.

    Indeed, for all the effort to reduce nuclear stockpiles to zero and to keep other nations (such as Iran) from developing nuclear capability, it seems that the Bomb is here to stay. In this gripping Very Short Introduction, Joseph M. Siracusa, an internationally respected authority on nuclear arms, provides a comprehensive, accessible, and at times chilling overview of the most deadly weapon ever invented. Siracusa explains the history of the arms race and the politics of the bomb, ranging from the technology of nuclear weapons, to the revolutionary implications of the H-bomb and the politics of nuclear deterrence. The issues are set against a backdrop of the changing international landscape, from the early days of development, through the Cold War, to the present-day controversy over George W. Bush's National Missile Defense, and the role of nuclear weapons in an Age of Terror. Providing an accessible and eye-opening backdrop to one of the most unsettling aspects of the modern world, this compact introduction is must reading.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics.

    Jan Westerhoff shows that the question "what is real?" is not some esoteric puzzle that only philosophers ponder. Scientists also ask this question when they investigate whether candidates for the fundamental constituents of matter are actually "out there" or just a mere abstraction from a successful theory and cognitive scientists ask it when trying to find out which set of the bewildering array of data processed by our brain could constitute the basis for the self.

    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.

    Travel fast enough and you could weigh as much as a jumbo jet, be flattened thinner than a CD without feeling a thing-and live forever! As for the angles of a triangle, they do not always have to add up to 180 degrees. And then, of course, there are black holes. These are but a few of the extraordinary consequences of Einstein's theory of relativity. It is now over a hundred years since he made these discoveries, and yet the general public is still largely unaware of them. Filled with illuminating anecdotes and fascinating accounts of experiments, this book aims to introduce the interested lay person to the subject of relativity in a way which is accessible and engaging and at the same time scientifically rigorous. With relatively few mathematical equations--nothing more complicated than the Pythagoras's Theorem--this VSI packs a lot time into very little space, and for anyone who has felt intimidated by Einstein's groundbreaking theory, it offers the perfect place to start.

    But what are thoughts? How does the brain--billions of tiny neurons and synapses--accomplish thought? In this compelling Very Short Introduction, Tim Bayne offers a compact but wide-ranging account of the nature of thought, drawing upon philosophy, psychology, neuroscience, and anthropology. Bayne touches on a stimulating array of topics. Does thinking occur in public or is it a purely private affair? Do young children and non-human animals think? Is human thought the same everywhere, or are there culturally specific modes of thought? What is the relationship between thought and language? What kind of responsibility do we have for our thoughts? In what ways can the process of thinking go wrong? Beginning with questions about what thought is and what distinguishes it from other kinds of mental states, he explores the logical structures of thought as well as the mechanisms that make thought possible. In sum, this book provides an engaging survey of what we know--and what we don't know--about one of the most central of human capacities.

    First, geologists realized that the continents themselves were drifting across the surface of the globe and that oceans were being created and destroyed. Secondly, pictures of the entire planet were returned from space. Suddenly, the Earth began to be viewed as a single entity; a dynamic, interacting whole, controlled by complex processes we scarcely understood. This Introduction explores emerging geological research and explains how new advances in the understanding of plate tectonics, seismology, and satellite imagery have enabled us to begin to see the Earth as it actually is: dynamic and ever changing.
