First published in 1999, this book explores how, from the stone bridges of neoclassicism which soar out of wild woods to span pastoral valleys to the post-1750 engineer’s bridge with its links to the more industrial landscape, the bridge was a popular feature in painting throughout the period 1700-1920. Why did so many artists choose to portray bridges? In this lavishly illustrated and intriguing book, John Sweetman seeks to answer this question. He traces the history of the bridge in painting and printmaking through a vast range of work, some as familiar as William Etty’s The Bridge of Sighs and Claude Monet’s The Railway Bridge at Argenteuil and others less well known such as Wassily Kandinsky’s Composition IV and C.R.W. Nevinson’s Looking Through the Brooklyn Bridge. Distinctive characteristics emerge revealing the complex role of the bridge as both symbol and metaphor, and as a place of vantage, meeting and separation.

On June 6, 1944, the Allies launched Operation Overlord, the largest, most hazardous amphibious assault in history. The objective: establishment of a lodgment area in Normandy from which the Allies could strike at the heart of Germany and destroy the German armed forces. Air supremacy over northwest Europe was an absolute prerequisite for the success of the invasion, and to achieve it the U.S. Army Air Forces launched two campaigns aimed at destroying the Germans' transportation advantages in the area. In the months and days leading up to the assault, the Army Air Forces ceaselessly bombed rail centers, rendering most of the railways in northern France and Belgium unusable. Once the actual invasion was underway, the Allies shifted to an interdiction campaign, using precise air attacks on critical transportation installations near the battlefield to neutralize Germany's efforts to resupply and reinforce their troops. This work makes use of many wartime records that had remained classified until recently.
Today, "community" seems to be everywhere. At home, at work, and online, the vague but comforting idea of the community pervades every area of life. But have we lost the ability truly to understand what it means? The Neighborhood in the Internet investigates social and civic effects of community networks on local community, and how community network designs are appropriated and extended by community members. Carroll uses his conceptual model of "community" to re-examine the Blacksburg Electronic Village – the first Web-based community network – applying it to attempts to sustain and enrich contemporary communities through information technology. The book provides an analysis of the role of community in contemporary paradigms for work and other activity mediated by the Internet. It brings to the fore a series of design experiments investigating new approaches to community networking and addresses the future trajectory and importance of community networks. This book will be of interest to students of sociology, community psychology, human-computer interaction, information science, and computer-supported collaborative work.
With the invention of compressed air in the 1840s, human divers could enter previously inaccessible deep water environments and engineers could design underwater mines and monumental bridges that had never been possible before. But a painful, sometimes fatal illness--decompression sickness, or the bends--mysteriously afflicted many of those who used compressed air. This book is a wide-ranging history of the wonders compressed air brought about and the suffering its unknown hazards inflicted. John L. Phillips explores the intertwining roles of science, technology, engineering, medicine, and politics in the invention of compressed air, the recognition and identification of decompression sickness, and the hundred-year-long process of learning to understand and treat the bends. The book begins with an overview of the biology and chemistry of respiration and a discussion of the steam engine that could generate compressed air. Drawing on previously unpublished letters, diaries, and notes, Phillips tells the story of early uses of compressed air, first observations of decompression sickness, growing awareness of the bends during construction of the Brooklyn Bridge, and efforts to understand the pathophysiology of the illness. He then considers employee health and safety issues, the science of diving today, and human limits to exploring the ocean deeps. In the history of compressed air and its illnesses, Phillips finds important lessons for dealing with other diseases yet to be confronted in the modern world.

Introduction When the study of heredity and variation first came to be treated as a scientific subject-and this, one must remember, was only just over a hundred years ago-there was an unfortunate separation between the disciplines of cytology and experimental breeding. This separation was based partly on a lack of understanding and partly on a lack of the desire to understand. Even WILLIAM BATESON, the first apostle of mendelism in England, had a blind spot for cytology and for many years dogmatically refused to believe that MENDEL'S determinants were transmitted and distributed by the chromosomes. This separation between cytology and experimental breeding is one which persists, in a measure, even today, simply because there are two quite different, though complementary, techniques available for the study of heredity and variation. On the one hand, one can study directly the structure and behaviour of the actual vehicles which transmit the genetic determinants from one generation to the next. This is the method employed by those who study genetics through a microscope. The alternative method is that used by the experimental breeder who, in default of being able to watch the hereditary factors segregate from each other directly, is obliged to examine the constitution of the germ cells indirectly by sampling, and usually at random, the products of a controlled mating.
In 1961 Smale established the generalized Poincare Conjecture in dimensions greater than or equal to 5 [129] and proceeded to prove the h-cobordism theorem [130]. This result inaugurated a major effort to classify all possible smooth and topological structures on manifolds of dimension at least 5. By the mid 1970's the main outlines of this theory were complete, and explicit answers (especially concerning simply connected manifolds) as well as general qualitative results had been obtained. As an example of such a qualitative result, a closed, simply connected manifold of dimension 2: 5 is determined up to finitely many diffeomorphism possibilities by its homotopy type and its Pontrjagin classes. There are similar results for self-diffeomorphisms, which, at least in the simply connected case, say that the group of self-diffeomorphisms of a closed manifold M of dimension at least 5 is commensurate with an arithmetic subgroup of the linear algebraic group of all automorphisms of its so-called rational minimal model which preserve the Pontrjagin classes [131]. Once the high dimensional theory was in good shape, attention shifted to the remaining, and seemingly exceptional, dimensions 3 and 4. The theory behind the results for manifolds of dimension at least 5 does not carryover to manifolds of these low dimensions, essentially because there is no longer enough room to maneuver. Thus new ideas are necessary to study manifolds of these "low" dimensions.
An engaging and delightfully illustrated account of the impact of railroads on the American built environment and on American culture from the last decades of the nineteenth century to the 1930's.
From the first century, when Buddhism entered China, the foreign religion shaped Chinese philosophy, beliefs, and ritual. At the same time, Buddhism had a profound effect on the material world of the Chinese. This wide-ranging study shows that Buddhism brought with it a vast array of objects big and small--relics treasured as parts of the body of the Buddha, prayer beads, and monastic clothing--as well as new ideas about what objects could do and how they should be treated. Kieschnick argues that even some everyday objects not ordinarily associated with Buddhism--bridges, tea, and the chair--on closer inspection turn out to have been intimately tied to Buddhist ideas and practices. Long after Buddhism ceased to be a major force in India, it continued to influence the development of material culture in China, as it does to the present day. At first glance, this seems surprising. Many Buddhist scriptures and thinkers rejected the material world or even denied its existence with great enthusiasm and sophistication. Others, however, from Buddhist philosophers to ordinary devotees, embraced objects as a means of expressing religious sentiments and doctrines. What was a sad sign of compromise and decline for some was seen as strength and versatility by others. Yielding rich insights through its innovative analysis of particular types of objects, this briskly written book is the first to systematically examine the ambivalent relationship, in the Chinese context, between Buddhism and material culture.

These notes were first used in an introductory course team taught by the authors at Appalachian State University to advanced undergraduates and beginning graduates. The text was written with four pedagogical goals in mind: offer a variety of topics in one course, get to the main themes and tools as efficiently as possible, show the relationships between the different topics, and include recent results to convince students that mathematics is a living discipline.
In the preceding 25 years to this book’s publication in 1985 there was an extensive and unprecedented burst of archaeological activity in evidence from below-ground deposits, above-ground structures, and artefacts. During the boom of the late 1960s and 1970s, which led to go much central town redevelopment, it was buried remains which yielded the most dramatic information. In the recession of the 1980s it was realised that upstanding remains had a lot to offer as well and they were being subject to ever more sophisticated study techniques. This book examines those recent developments in archaeology and assesses their bearing on the study of medieval English and Welsh history. Taking a series of important themes such as government, religion and the countryside, the book offers a chronological approach from the coming of the Vikings, 850 AD, to the Reformation in 1530. This approach focuses on the impact of man on the urban and rural landscape. An important text for students of ancient history.
