About this ebook

When planes crash, bridges collapse, and automobile gas tanks explode, we are quick to blame poor design. But Henry Petroski says we must look beyond design for causes and corrections. Known for his masterly explanations of engineering successes and failures, Petroski here takes his analysis a step further, to consider the larger context in which accidents occur.

In To Forgive Design he surveys some of the most infamous failures of our time, from the 2007 Minneapolis bridge collapse and the toppling of a massive Shanghai apartment building in 2009 to Boston's prolonged Big Dig and the 2010 Gulf oil spill. These avoidable disasters reveal the interdependency of people and machines within systems whose complex behavior was undreamt of by their designers, until it was too late. Petroski shows that even the simplest technology is embedded in cultural and socioeconomic constraints, complications, and contradictions.

Failure to imagine the possibility of failure is the most profound mistake engineers can make. Software developers realized this early on and looked outside their young field, to structural engineering, as they sought a historical perspective to help them identify their own potential mistakes. By explaining the interconnectedness of technology and culture and the dangers that can emerge from complexity, Petroski demonstrates that we would all do well to follow their lead.

About the author

Henry Petroski is an American engineer with wide-ranging historical and sociocultural interests. He earned a Ph.D. in theoretical and applied mechanics from the University of Illinois at Urbana-Champaign in 1968, and became Aleksandar S. Vesic professor and chair of the Department of Civil and Environmental Engineering at Duke University. Petroski teaches traditional engineering subjects, as well as courses for nonengineering students, that place the field in a broad social context. One of the major themes that transcends his technical and nontechnical publications is the role of failure and its contribution to successful design. This is the central theme in his study To Engineer Is Human: The Role of Failure in Successful Design, which is accessible to both engineers and general readers. This theme is also incorporated into Petroski's The Pencil: A History of Design and Circumstance (1990), which relates the history of the pencil to broader sociocultural themes. The theme is expanded further, illustrating the relationship of engineering to our everyday life in The Evolution of Useful Things (1992). Petroski's most recent book, Design Paradigms: Case Histories of Error and Judgment in Engineering, is planned for publication in 1994. After that, he will begin a study of the complex interrelationships between engineering and culture. Widely recognized and supported by both the technical and humanities communities, Petroski's work has effectively conveyed the richness and essence of engineering in its societal context for the general reader.
