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.

    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.

    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.

    But in this spirited Very Short Introduction, famed critic Terry Eagleton takes a serious if often amusing look at the question and offers his own surprising answer.Eagleton first examines how centuries of thinkers and writers--from Marx and Schopenhauer to Shakespeare, Sartre, and Beckett--have responded to the ultimate question of meaning. He suggests, however, that it is only in modern times that the question has become problematic. But instead of tackling it head-on, many of us cope with the feelings of meaninglessness in our lives by filling them with everything from football to sex, Kabbala, Scientology, New Age softheadedness, or fundamentalism. On the other hand, Eagleton notes, many educated people believe that life is an evolutionary accident that has no intrinsic meaning. If our lives have meaning, it is something with which we manage to invest them, not something with which they come ready made. Eagleton probes this view of meaning as a kind of private enterprise, and concludes that it fails to holds up. He argues instead that the meaning of life is not a solution to a problem, but a matter of living in a certain way. It is not metaphysical but ethical. It is not something separate from life, but what makes it worth living--that is, a certain quality, depth, abundance and intensity of life.Here then is a brilliant discussion of the problem of meaning by a leading thinker, who writes with a light and often irreverent touch, but with a very serious end in mind.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics.

    Looking at texts ranging from the Gospels from NagHammadi to the Dialogues with the Risen Savior, Paul Foster shows how the apocryphal gospels reflect the diversity that existed within early Christianity, and considers the extent to which they can be used to reconstruct an accurate portrait of the historical Jesus. Foster demonstrates how closeanalysis of text, contents, and context are vital in assessing the value and authenticity of such ancient documents. Including discussions of controversies and case-studies such as the alleged hoax surrounding the discovery of Secret Mark, Foster concludes that the non-canonical texts, considered inthe correct context, can help us reach a more complete understanding of the multi-faceted nature of early Christianity.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics.

    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.

    As humans, we decipher the meaning of newspaper articles, books, legal matters, religious texts, political speeches, emails, and even dinner conversations every day . But how is knowledge mediated through these forms? What constitutes the process of interpretation? And how do we draw meaning from the world around us so that we might understand ourposition in it?In this Very Short Introduction Jens Zimmermann traces the history of hermeneutic theory, setting out its key elements, and demonstrating how they can be applied to a broad range of disciplines: theology; literature; law; and natural and social sciences. Demonstrating the longstanding and wide-ranging necessity of interpretation, Zimmermann reveals its significance in our current social and political landscape.ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area.

    Indeed, this relatively small group of twenty-seven works, written during the height of the Roman Empire, not only helped create and sustain a vast world religion, but also have been integral to the larger cultural dynamics of the West, above and beyond particular religious expressions. Looking at the New Testament through the lens of literary study, Kyle Keefer offers an engrossing exploration of this revered religious text as a work of literature, but also keeps in focus its theological ramifications. Unique among books that examine the Bible as literature, this brilliantly compact introduction offers an intriguing double-edged look at this universal text—a religiously informed literary analysis. The book first explores the major sections of the New Testament—the gospels, Paul's letters, and Revelation—as individual literary documents. Keefer shows how, in such familiar stories as the parable of the Good Samaritan, a literary analysis can uncover an unexpected complexity to what seems a simple, straightforward tale. At the conclusion of the book, Keefer steps back and asks questions about the New Testament as a whole. He reveals that whether read as a single document or as a collection of works, the New Testament presents readers with a wide variety of forms and viewpoints, and a literary exploration helps bring this richness to light. A fascinating investigation of the New Testament as a classic literary work, this Very Short Introduction uses a literary framework—plot, character, narrative arc, genre—to illuminate the language, structure, and the crafting of this venerable text.

    Readers will find an enlightening history of the vacuum: how the efforts to make a better vacuum led to the discovery of the electron; the ideas of Newton, Mach, and Einstein on the nature of space and time; the mysterious aether and how Einstein did away with it; and the latest ideas that the vacuum is filled with the Higgs field. The story ranges from the absolute zero of temperature and the seething vacuum of virtual particles and anti-particles that fills space, to the extreme heat and energy of the early universe.

    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.

    During his reign he conquered the Achaemenid Persian Empire, the largest empire that had ever existed, leading his army from Greece to Pakistan, and from the Libyan desert to the steppes of Central Asia. His meteoric career, as leader of an alliance of Greek cities, Pharaoh of Egypt, and King of Persia, had a profound effect on the world he moved through. Even in his lifetime his achievements became legendary and in the centuries that following his story was told and retold throughout Europe and the East. Greek became the language of power in the Eastern Mediterranean and much of the Near East, as powerful Macedonian dynasts carved up Alexander's empire into kingdoms of their own, underlaying the flourishing Hellenistic civilization that emerged after his death.But what do we really know about Alexander? In this Very Short Introduction, Hugh Bowden goes behind the usual historical accounts of Alexander's life and career. Instead, he focuses on the evidence from Alexander's own time -- letters from officials in Afghanistan, Babylonian diaries, records from Egyptian temples -- to try and understand how Alexander appeared to those who encountered him. In doing so he also demonstrates the profound influence the legends of his life have had on our historical understanding and the controversy they continue to generate worldwide.ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area.

    Aquinas was a controversial figure in his time who was often engaged in fierce theological debates. He was the foremost classical proponent of naturaltheology, and the father of the Thomistic school of philosophy and theology. This Very Short Introduction will look at Aquinas in a historical context, and explore the Church and culture into which Aquinas was born. It will consider Aquinas as philosopher and theologian, and will look at therelationship between philosophy and religion in the thirteenth century. Fergus Kerr, in this engaging and informative introduction, makes the Summa Theologiae, Aquinas's greatest single work, accessible to new readers. He also sheds valuable light on the importance of Thomas Aquinas in modern times, showing why Aquinas matters now, illustrating the significant role that the writings of Aquinas play in contemporary debate.

    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.

    This very short introduction to the condition offers a clear statement on what is currently known about autism and Asperger's syndrome.

    It traces the history and cultural impact of the elements on humankind, and examines why people have long sought to identify thesubstances around them. The book includes chapters on particular elements such as gold, iron, and oxygen, showing how they shaped culture and technology. Looking beyond the Periodic Table, the author examines our relationship with matter, from the uncomplicated vision of the Greek philosophers, whobelieved there were four elements--earth, air, fire, and water--to the work of modern-day scientists in creating elements such as hassium and meitnerium. Packed with anecdotes, The Elements is a highly engaging and entertaining exploration of the fundamental question: what is the world made from?
