At a time when we are reexamining our values, reeling from the pace of change, witnessing the clash between good instincts and "pragmatism," dealing with the angst of a new millennium, Neil Postman, one of our most distinguished observers of contemporary society, provides for us a source of guidance and inspiration. In Building a Bridge to the Eighteenth Century he revisits the Enlightenment, that great flowering of ideas that provided a humane direction for the future -- ideas that formed our nation and that we would do well to embrace anew. He turns our attention to Goethe, Voltaire, Rousseau, Diderot, Kant, Edward Gibbon, Adam Smith, Thomas Paine, Jefferson, and Franklin, and to their then-radical thinking about inductive science, religious and political freedom, popular education, rational commerce, the nation-state, progress, and happiness. Postman calls for a future connected to traditions that provide sane authority and meaningful purpose -- as opposed to an overreliance on technology and an increasing disregard for the lessons of history. And he argues passionately for specific new guidelines in the education of our children, with renewed emphasis on developing the intellect as successfully as we are developing a computer-driven world. Witty, provocative, and brilliantly reasoned, Building a Bridge to the Eighteenth Century is Neil Postman's most radical, and most commonsensical, book yet. From the Hardcover edition.

Modern structural engineering surprises us with the mastery and certainty with which it plans and carries out daring projects, such as the most recent metal or concrete bridges, whether they be suspension or arch bridges. On the other hand, little is yet known about the state of knowledge of construction science and techniques which, well before the arrival of modern methods based on the mechanics of deformable continua, made it possible in the past to erect the vaulted masonry structures rthat we have inherited. The fact that these have lasted through many centuries to our time, and are still in a fairly good state of conservation, makes them competitive, as far as stability and durability are concerned, with those constructed in other materials. Although it is known that the equilibrium of the arch is guaranteed by any funicular whatsoever of the loads, contained inside the profile of an arch, finding the unique solution is not such a certainty. In other words, the problem of the equilibrium of vaulted structures is 'Poleni's problem', the one for which the Venetian scientist was able to give an exemplary solution on the occasion of the assessment of the dome of St. Peter's. Arch Bridges focuses on the main aspects of the debate about the masonry arch bridge: History of structural mechanics and construction, theoretical models, analysis for assessment, numerical methods, experimental and non-destructive testing, maintenance and repair are the topics of the Conference. The breadth and variety of the contributions presented and discussed by leading experts from many countries make this volume an authoritative source of up-to-date information.

In the twentieth century bridge engineers have seen many changes. Advances in technology, materials and engineers understanding of structural behaviour and methods of analysis has presented opportunities for innovation and have led to increasingly sophisticated solutions to the basic problem of providing a bridge over an obstacle. However, despite these innovative technological changes, the masonry arch bridge has shown itself to be a durable, cost-effective structure, tolerant of its modern environment and out-performing many of its competitors. In recent years arch bridges in the West have been built using reinforced concrete or steel construction; whilst in China, masonry arch bridges have continued to enjoy popularity, and there is a growing realisation in the UK that masonry arch bridges offer longevity and environmental acceptance. Arch bridges brings together current knowledge on all aspects of bridge behaviour. Leading experts from over ten counties give details of the latest developments in construction, design, analysis, repair, and maintenance. Using case histories to illustrate the methods used, this book provides an authoritative source of information which is vital to the industry if the current renaissance in arch bridge building is to be sustained.

Engineers have always had a huge influence on the way we live and how our world looks. They create lasting solutions to the biggest challenges, and construct iconic and incredible buildings that have literally stood the test of time. Engineers tells their story, from the men who built the Great Pyramid in Egypt to the pioneers of space travel. Often many different minds worked together or built on the work of previous generations to achieve a working version of a great idea: Engineers explores this progression of ideas, from initial concept to prototype and finished design. The great achievements of engineers go hand in hand with the world's greatest structures, such as aqueducts, monuments, bridges, and dams. These works are shown in detail and highlighted with beautiful illustrations, photographs, and technical drawings.

Surviving Technopolis

Technopolis has no end in view other than bigger, faster, newer, and more. While giving us many material benefits--at least in the short run--in its wake are spiritual loss, alienation, and devastation. These essays not only evaluate Technopolis, but also seek wisdom to cope with our new human-made environments. Positively stated, they offer suggestions on how to bring us back into balance. Some of our best wisdom in analyzing Technopolis can be found in the voices of the Christian humanists. Unlike Enlightenment humanism, which tends to be human-centered, Christian humanism is concerned with the role of humankind within God's created order. G. K. Chesterton, T. S. Eliot, J. R. R. Tolkien, and C. S. Lewis represent this tradition. They, and others like them, understood that technological progress with no clear telos obscures what Eliot called the permanent things. Surviving Technopolis means restoring the things closest to us--those old identity-forming institutions of home, church, and community.
