Not only are galaxies fascinatingastronomical structures in themselves, but their study has revealed much of what we know today about the cosmos, providing a window on the Big Bang and the origins of the Universe. Gribben looks at our own Milky Way Galaxy in detail, from the different kinds of stars that are born within it, tothe origins of its magnificent spiral structure. Perhaps most interesting, Gribben describes the many exciting discoveries have been made about our own galaxy and about those beyond: how a supermassive black hole lurks at the center of every galaxy, how enormous forces are released when galaxiescollide, how distant galaxies provide a window on the early Universe, and how the formation of young galaxies shed needed light on the mysteries of Cold Dark Matter.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics.

    From deserts to jungles, from deep caves to mountain tops, from pebble tools to satellite photographs, from excavation to abstract theory, archaeology interacts with nearly every other discipline in its attempts to reconstruct the past.

    The name dinosaur was coined in 1842 by an English anatomist Richard Owen, a highly ambitious, machiavellian schemer and villain of Deborah Cadbury's The Dinosaur Hunters: A True Story of Scientific Rivalry and the Discovery of the Prehistoric World. Her hero is Gideon Mantell, a practising doctor, who found and first described many of the bones of the beasts that subsequently became known as dinosaurs. Full of quotes from contemporary sources, The Dinosaur Hunters brilliantly evokes the Dickensian world of early Victorian science and society. From Mary Anning, the self-taught fossil hunter of Lyme Regis to the academic and deeply eccentric Dean Buckland of Oxford University, the story tells of reputations made and lost as self-help, self-promotion, over-wheening pride, folly and social climbing all played their part in the emerging story of the geological past. The dinosaurs, although central to the story, are also a vehicle for the much larger, more interesting and important story about the struggle to understand the meaning of fossils and what they tell us about prehistory. Deborah Cadbury, an award-winning TV science producer and acclaimed author of The Feminisation of Nature has thoroughly researched her topic and steeped herself in the intricacies of the scientific debates of the time. With black and white illustrations, extensive notes, a bibliography and index, the result is one of the best popular science histories. --Douglas Palmer.

    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.

    Yet Vikings were also traders, settlers, and farmers, with a complex artistic and linguistic culture, whose expansion overseas led them to cross the Atlantic for the first time in European history. Highlighting the latest archaeological evidence, Julian Richards reveals the whole Viking world: their history, their culture, and their legacy of overseas expansion for trade, colonization, and plunder. Viking identity is explored through what we have learned about their towns, art, shipbuilding, and religious rituals. Here the Viking story is brought up to the present, from the tales of adventure found in medieval Icelandic sagas, to their exploitation as a symbol of nationalism in the nineteenth century by Wagner, and later by Hitler and the Nazi party. The author also highlights their impact and influence on the history and people of Northern Europe. Vikings, a fascinating new look at a people and culture that have been reinvented throughout history, will take readers closer to discovering who they really were.

    These, along with the introduction of the oral contraceptive, have altered all of our lives. There has also been an increase in the recreational use and abuse of drugs in the Western world. This Very Short Introduction gives a non-technical account of how drugs act on the body and how therapeutic drugs are developed and tested, then goes on to review both legal (prescription, alcohol, nicotine, and caffeine) and illegal drugs, and discuss current ideas about why some drugs are addictive, and whether drug laws need reform.

    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.

    In this Very Short Introduction, eminent biologist and popular science writer Dorothy Crawford offers a fascinating portrait of these infinitesimally small but often highly dangerous creatures. Crawford first relates how viruses were discovered and she unravels the intricate structures of tiny parasites that are by far the most abundant life forms on the planet. Analyzing the threat of viral infections, Crawford recounts stories of renowned killer viruses such as Ebola and rabies as well as the less known bat-borne Nipah and Hendra viruses. She identifies wild animals as the source of the most recent pandemics, detailing the reasons behind the present increase in potentially fatal infections, and evaluating the evidence that suggests that long term viruses can eventually lead to cancer. Finally, Crawford looks to the future to ask whether we can ever live in harmony with viruses, and considers ways to prevent the emergence of new and devastating viruses.

    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.

    Egyptian Mythology: A Very Short Introduction explains the cultural and historical background to the fascinating and complex world of Egyptian myth, with each chapter dealing with a particular theme.To show the variety of source material for Egyptian myth, each chapter features a particular object--such as the obelisk known as Cleopatra's Needle, a golden statue of Tutankhamun, and a papyrus containing a story in which the Egyptian gods behave outrageously--which is illustrated by a photograph or line-drawing. The myth "The Contendings of Horus and Seth" is looked at in detail, and the many interpretations it has provoked are examined. In addition to a list of major deities and myths, there are explanations of related topics such as how hieroglyphs work, royal names and titles, and the Egyptian cosmos. There is also a timeline of Egyptian history, a glossary of technical terms and an up-to-date bibliography.

    Readers meet a people highly skilled in sculpture, astronomy, city planning, poetry, and philosophy, who were also profoundly committed tocosmic regeneration through the thrust of the ceremonial knife and through warfare. Dav�d Carrasco looks beyond Spanish accounts that have colored much of the Western narrative to let Aztec voices speak about their origin stories, the cosmic significance of their capital city, their methods of childrearing, and the contributions women made to daily life and the empire. Carrasco discusses the arrival of the Spaniards, contrasts Aztec mythical traditions about the origins of their city with actual urban life in Mesoamerica, and outlines the rise of the Aztec empire. He also explores Aztecreligion, which provided both justification for and alternatives to warfare, sacrifice, and imperialism, and he sheds light on Aztec poetry, philosophy, painting, and especially monumental sculpture and architecture. He concludes by looking at how the Aztecs have been portrayed in Western thought, art, film, and literature as well as in Latino culture and arts.

    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.

    Even today, the war inspires countless articles and books, extensive archaeological excavations, movies, television documentaries, even souvenirs and collectibles. Butwhile the ancients themselves believed that the Trojan War took place, scholars of the modern era have sometimes derided it as a piece of fiction.Combining archaeological data and textual analysis of ancient documents, this Very Short Introduction considers whether or not the war actually took place and whether archaeologists have really discovered the site of ancient Troy. To answer these questions, archaeologist and ancient historian EricH. Cline examines various written sources, including the works of Homer, the Epic Cycle (fragments from other, now-lost Greek epics), classical plays, and Virgil's Aeneid. Throughout, the author tests the literary claims against the best modern archaeological evidence, showing for instance thatHomer, who lived in the Iron Age, for the most part depicted Bronze Age warfare with accuracy. Cline also tells the engaging story of the archaeologists--Heinrich Schliemann and his successors Wilhelm Dörpfeld, Carl Blegen, and Manfred Korfmann--who found the long-vanished site of Troy throughexcavations at Hisarlik, Turkey.Drawing on evidence found at Hisarlik and elsewhere, Cline concludes that a war or wars in the vicinity of Troy probably did take place during the Late Bronze Age, forming the nucleus of a story that was handed down orally for centuries until put into final form by Homer. But Cline suggests that, even allowing that a Trojan War took place, it probably was not fought because of Helen's abduction, though such an incident may have provided the justification for a war actually fought for more compelling economic and political motives.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.
