Here are two dozen tales in the grand adventure of engineering from the Henry Petroski, who has been called America's poet laureate of technology. Pushing the Limits celebrates some of the largest things we have created-bridges, dams, buildings--and provides a startling new vision of engineering's past, its present, and its future. Along the way it highlights our greatest successes, like London's Tower Bridge, our most ambitious projects, like China's Three Gorges Dam, our most embarrassing moments, like the wobbly Millennium Bridge in London, and our greatest failures, like the collapse of the twin towers on September 11. Throughout, Petroski provides fascinating and provocative insights into the world of technology with his trademark erudition and enthusiasm for the subject.
