A historical look at styles of technological research and design. If it is true, as Tocqueville suggested, that social and class systems shape technology, research, and knowledge, then the effects should be visible both at the individual level and at the level of technical institutions and local environments. That is the central issue addressed in Constructing a Bridge, a tale of two cultures that investigates how national traditions shape technological communities and their institutions and become embedded in everyday engineering practice. Eda Kranakis first examines these issues in the work of two suspension bridge designers of the early nineteenth century: the American inventor James Finley and the French engineer Claude-Louis-Marie-Henri Navier. Finley--who was oriented toward the needs of rural, frontier communities--designed a bridge that could be easily reproduced and constructed by carpenters and blacksmiths. Navier--whose professional training and career reflected a tradition of monumental architecture and had linked him closely to the Parisian scientific community--designed an elegant, costly, and technically sophisticated structure to be built in an elite district of Paris. Charting the careers of these two technologists and tracing the stories of their bridges, Kranakis reveals how local environments can shape design goals, research practices, and design-to-construction processes. Kranakis then offers a broader look at the technological communities and institutions of nineteenth-century France and America and at their ties to technological practice. She shows how conditions that led to Finley's and Navier's distinct designs also fostered different systems of technical education as well as distinct ideologies and traditions of engineering research.The result of this two-tiered, comparative approach is a reorientation of a historiographic tradition initiated by Tocqueville (and explored more recently by Eugene Ferguson, John Kasson, and others) toward a finer-grained analysis of institutional and local environments as mediators between national traditions and individual styles of technological research and design.

“A treasure...a wise and entertaining book that should appeal to the spiritual pilgrim in all of us, no matter what the faith and no matter whether believer or nonbeliever.” – Chicago Tribune The New York Times bestselling author of The Jesuit Guide to (Almost) Everything and Jesus: A Pilgrimage turns his attention to the relationship between LGBT Catholics and the Church in this loving, inclusive, and revolutionary book. A powerful call for tolerance, acceptance, and support—and a reminder of Jesus' message for us to love one another. In this moving and inspiring book, Martin offers a powerful, loving, and much-needed voice in a time marked by anger, prejudice, and divisiveness. On the day after the Orlando nightclub shooting, James Martin S.J. posted a video on Facebook in which he called for solidarity with our LGBT brothers and sisters. "The largest mass shooting in US history took place at a gay club and the LGBT community has been profoundly affected," he began. He then implored his fellow Catholics—and people everywhere—to "stand not only with the people of Orlando but also with their LGBT brothers and sisters." Father Martin's post went viral and was viewed more than 1.6 million times. Adapted from an address he gave to New Ways Ministry, a group that ministers to and advocates for LGBT Catholics, Building a Bridge provides a roadmap for repairing and strengthening the bonds that unite all of us as God's children. Martin uses the image of a two-way bridge to enable LGBT Catholics and the Church to come together in a call to end the "us" versus "them" mentality. Turning to the Catechism, he draws on the three criteria at the heart of the Christian ministry—"respect, compassion, and sensitivity"—as a model for how the Catholic Church should relate to the LGBT community.

Readers construct and test their own bridges to help the Gingerbread Man escape a fox. With colorful spreads featuring fun facts, sidebars, and infographics, this book provides an engaging overview of the science and engineering of bridges.

Silver Award Winner, 2016 Nautilus Book Award in Young Adult (YA) Non-Fiction Moving beyond the familiar accounts of politics and the achievements of celebrity engineers and designers, Building the Golden Gate Bridge is the first book to primarily feature the voices of the workers themselves. This is the story of survivors who vividly recall the hardships, hazards, and victories of constructing the landmark span during the Great Depression. Labor historian Harvey Schwartz has compiled oral histories of nine workers who helped build the celebrated bridge. Their powerful recollections chronicle the technical details of construction, the grueling physical conditions they endured, the small pleasures they enjoyed, and the gruesome accidents some workers suffered. The result is an evocation of working-class life and culture in a bygone era. Most of the bridge builders were men of European descent, many of them the sons of immigrants. Schwartz also interviewed women: two nurses who cared for the injured and tolerated their antics, the wife of one 1930s builder, and an African American ironworker who toiled on the bridge in later years. These powerful stories are accompanied by stunning photographs of the bridge under construction. An homage to both the American worker and the quintessential San Francisco landmark, Building the Golden Gate Bridge expands our understanding of Depression-era labor and California history and makes a unique contribution to the literature of this iconic span.

Discusses the history of bridges, improvements that have made them safer, and bridge disasters.

Marvin Denmark, a builder and craftsman with 45+ years of experience, demonstrates the process he used to design and construct a small cable suspension bridge. This book includes some suspension bridge history along with engineering considerations, then explains and illustrates with diagrams and full-color photos the step by step process that was used to complete the project. His blog, wildcatman.wordpress.com, has excerpts from the book, a new cable locking system design, and a recent price list for parts for his bridge. A trailer for the cable locking system including video of the bridge building process is here:http://www.youtube.com/watch?v=cLXrzC9K5wQ Anyone who is looking for ideas for a footbridge that is relatively easy to build without the use of heavy equipment or difficult to replace components may benefit from the design in this book and by using the patented "cable locking system."

This title discusses how bridges are built, including engineering, design and construction.
