According to these sources, they were a learned caste who officiated in religious ceremonies, taught the ancient wisdoms, and were revered as philosophers. But few figures flit so elusively through history, and the Druids remain enigmatic and puzzling to this day. In this Very Short Introduction, one of the leading authorities on British archaeology, Barry Cunliffe, takes the reader on a fast-paced look at the ever-fascinating story of the Druids, as seen in the context of the times and places in which they practiced. Sifting through the evidence, Cunliffe offers an expert's best guess as to what can be said and what can't be said about the Druids, discussing the origins of the Druids and the evidence for their beliefs and practices, why the nature of the druid caste changed quite dramatically over time, and how successive generations have seen them in very different ways.

    In this Very Short Introduction, Robert Eaglestone provides a clear and engaging exploration of the major themes, patterns, and debates of contemporary fiction. From genre, form, and experimentalism to the legacies of modernism and postmodernism, the relationship between globalization and terrorism, and the impact of technology, Eaglestone examines how works both reflect the world in which we live and the artistic concerns of writers and readers alike.

    It is also one of the most controversial. It clashes, or is widely thought to clash, with many conventional moral views, and with human rights when they are seen as inviolable. Would it, for example, be right to torture a suspected terrorist in order to prevent an attack that could kill and injure a large number of innocent people? In this Very Short Introduction Peter Singer and Katarzyna de Lazari-Radek provide an authoritative account of the nature of utilitarianism, from its nineteenth-century origins, to its justification and its varieties. Considering how utilitarians can respond to objections that are often regarded as devastating, they explore the utilitarian answer to the question of whether torture can ever be justified. They also discuss what it is that utilitarians should seek to maximize, paying special attention to the classical utilitarian view that only pleasure or happiness is of intrinsic value.Singer and de Lazari-Radek conclude by analyzing the continuing importance of utilitarianism in the world, indicating how it is a force for new thinking on contemporary moral challenges like global poverty, the treatment of animals, climate change, reducing the risk of human extinction, end-of-life decisions for terminally-ill patients, and the shift towards assessing the success of government policies in terms of their impact on happiness.

    How closely linked are migrants with terrorist organizations? What factors lie behind the dramatic increase in the number of woman migrating? This Very Short Introduction looks at the global phenomenon of human migration--both legal and illegal-revealing how migration actually presents opportunities that must be taken advantage of in light of the current economic climate. The author debunks myths such as the claim that migrants take jobs away from local workers, or that they take advantage of health care systems. He reveals why society as we now know it could not function without them.Using interviews with migrants from around the world, the author presents the human side of topics such as asylum and refugees, human trafficking, migrant smuggling, development, and the international labor force. His goal throughout is to allow readers to see beyond the negative spin usually given the subject by the media and politicians, and come to their own conclusions on the current international migration situation. It is a valuable reference for students of economics, politics, geography, or sociology, and for anyone interested in taking a deeper look at media coverage of immigration and its effects.

    It enables us to understand the structure and evolution of planetary systems, stars, galaxies, interstellar gas, and the cosmos as a whole.In this Very Short Introduction, the leading astrophysicist James Binney shows how the field of astrophysics has expanded rapidly in the past century, with vast quantities of data gathered by telescopes exploiting all parts of the electromagnetic spectrum, combined with the rapid advance of computing power, which has allowed increasingly effective mathematical modelling. He illustrates how the application of fundamental principles of physics - the consideration of energy and mass, and momentum - and the two pillars of relativity and quantum mechanics, has provided insights into phenomena ranging from rapidly spinning millisecond pulsars to the collision of giant spiral galaxies. This is a clear, rigorous introduction to astrophysics for those keen to cut their teeth on a conceptual treatment involving some mathematics.ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area.

    Hardy, in the years before World War I. Through their eyes the reader is taken on a journey through numbers theory. Ramanujan would regularly telescope 12 steps of logic into two - the effect is said to be like Dr Watson in the train of some argument by Sherlock Holmes. The language of symbols and infinitely large (and small) regions of mathematics should be rendered with clarity for the general reader.

    In this accessible and stimulating Very Short Introduction, Martin Bunton illuminates the history of the problem, reducing it to its very essence. Adopting a fresh and original approach, Bunton explores the Palestinian-Israeli dispute in twenty-year segments, to highlight the historical complexity of the conflict throughout successive decades. Each chapter starts with an examination of the relationships among people and events that marked particular years as historical stepping stones in the evolution of the conflict, including the 1897 Basle Congress, the 1917 Balfour Declaration and British occupation of Palestine, and the 1947 UN Partition Plan and the war for Palestine.Providing a clear and fair exploration of the main issues, Bunton explores not only the historical basis of the conflict, but also looks at how and why partition has been so difficult and how efforts to restore peace continue today.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.

    This Very Short Introduction examines and untangles the various strands of anti-Semitism seen throughout history, revealing why hatred of the Jews appears to be so persistent through time. Steven Beller illuminates the history of the phenomenon: from medieval religious conflict, to the growth of anti-Semitism as a political and ideological movement in the 19th century, to the "new" anti-Semitism of the 21st century, as reflected in Holocaust denial and Islamic anti-Zionism. The author also discusses the role and attitudes of key figures such as Wagner, Nietzsche, and Marx, as well as key texts such as the forged "Protocols of the Elders of Zion." In short, this compact book offers an insightful account that underscores how anti-Semitism reached it its dark apogee in the worst genocide in modern history--the Holocaust--and how it still persists around the world today.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.

    Growing understanding of the immune system, and especially the creation of immune memory (long lasting protection), which can be harnessed in the design of vaccines, have been major breakthroughs in medicine.In this Very Short Introduction, Paul Klenerman describes the immune system, and how it works in health and disease. In particular he focuses on the human immune system, considering how it evolved, the basic rules that govern its behavior, and the major health threats where it is important. Theimmune system comprises a series of organs, cells and chemical messengers which work together as a team to provide defence against infection. Klenerman discusses these components, the critical signals that trigger them and how they exert their protective effects, including so-called innate immuneresponses, which react very fast to infection, and adaptive immune responses, which have huge diversity and a capacity to recognize and defend against a massive array of micro-organisms. Klenerman also considers what happens when our immune systems fail to be activated effectively, leading toserious infections, problems with inherited diseases, and also HIV/AIDS. At the opposite extreme, as Klenerman shows, an over-exaggerated immune response leads to inflammatory diseases such as Multiple Sclerosis and Rheumatoid Arthritis, as well as allergy and asthma. Finally he looks at the Immunesystem v2.o - how immune therapies and vaccines can be advanced to protect us against the major diseases of the 21st century.ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area.

It does not disguise the problems of interpretation that still remain unsettled 75 years after the initial discoveries. The main text makes no use of equations, but there is a Mathematical Appendix for those desiring stronger fare. Uncertainty, probabilistic physics, complementarity, the problematic character of measurement, and decoherence are among the many topics discussed. This volume offers the reader access to one of the greatest discoveries in the history of physics and one of the outstanding intellectual achievements of the twentieth century.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.

    Is God a Mathematician? investigates why mathematics is as powerful as it is. From ancient times to the present, scientists and philosophers have marveled at how such a seemingly abstract discipline could so perfectly explain the natural world. More than that—mathematics has often made predictions, for example, about subatomic particles or cosmic phenomena that were unknown at the time, but later were proven to be true. Is mathematics ultimately invented or discovered? If, as Einstein insisted, mathematics is “a product of human thought that is independent of experience,” how can it so accurately describe and even predict the world around us? Physicist and author Mario Livio brilliantly explores mathematical ideas from Pythagoras to the present day as he shows us how intriguing questions and ingenious answers have led to ever deeper insights into our world. This fascinating book will interest anyone curious about the human mind, the scientific world, and the relationship between them.

    Even when dealing with standard material, Stillwell manages to dramatize it and to make it worth rethinking. In short, his book is a splendid addition to the genre of works that build royal roads to mathematical culture for the many." (Mathematical Intelligencer)This second edition includes new chapters on Chinese and Indian number theory, on hypercomplex numbers, and on algebraic number theory. Many more exercises have been added, as well as commentary to the exercises explaining how they relate to the preceding section, and how they foreshadow later topics.

    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.

    One simply could not put a numerical value on the likelihood that a particular event would occur. Even the outcome of something as simple as a dice roll or the likelihood of showers instead of sunshine was thought to lie in the realm of pure, unknowable chance.The issue remained intractable until Blaise Pascal wrote to Pierre de Fermat in 1654, outlining a solution to the “unfinished game” problem: how do you divide the pot when players are forced to end a game of dice before someone has won? The idea turned out to be far more seminal than Pascal realized. From it, the two men developed the method known today as probability theory.In The Unfinished Game, mathematician and NPR commentator Keith Devlin tells the story of this correspondence and its remarkable impact on the modern world: from insurance rates, to housing and job markets, to the safety of cars and planes, calculating probabilities allowed people, for the first time, to think rationally about how future events might unfold.
