Bøger af Henry Petroski

Why has the durable paper shopping bag been largely replaced by its flimsy plastic counterpart? What circuitous chain of improvements led to such innovations as the automobile cup holder and the swiveling vegetable peeler? With the same relentless curiosity and lucid, witty prose he brought to his earlier books, Henry Petroski looks at some of our most familiar objects and reveals that they are, in fact, works in progress. For there can never be an end to the quest for the perfect design. To illustrate his thesis, Petroski tells the story of the paper drinking cup, which owes its popularity to the discovery that water glasses could carry germs. He pays tribute to the little plastic tripod that keeps pizza from sticking to the box and analyzes the numerical layouts of telephones and handheld calculators. Small Things Considered is Petroski at his most trenchant and provocative, casting his eye not only on everyday artifacts but on their users as well.

Design pervades our lives. Everything from drafting a PowerPoint presentation to planning a state-of-the-art bridge embodies this universal human activity. But what makes a great design? In this compelling and wide-ranging look at the essence of invention, distinguished engineer and author Henry Petroski argues that, time and again, we have built success on the back of failure--not through easy imitation of success. Success through Failure shows us that making something better--by carefully anticipating and thus averting failure--is what invention and design are all about. Petroski explores the nature of invention and the character of the inventor through an unprecedented range of both everyday and extraordinary examples--illustrated lectures, child-resistant packaging for drugs, national constitutions, medical devices, the world's tallest skyscrapers, long-span bridges, and more. Stressing throughout that there is no surer road to eventual failure than modeling designs solely on past successes, he sheds new light on spectacular failures, from the destruction of the Tacoma Narrows Bridge in 1940 and the space shuttle disasters of recent decades, to the collapse of the World Trade Center in 2001. Petroski also looks at the prehistoric and ancient roots of many modern designs. The historical record, especially as embodied in failures, reveals patterns of human social behavior that have implications for large structures like bridges and vast organizations like NASA. Success through Failure--which will fascinate anyone intrigued by design, including engineers, architects, and designers themselves--concludes by speculating on when we can expect the next major bridge failure to occur, and the kind of bridge most likely to be involved.

When planes crash, bridges collapse, and automobile gas tanks explode, we are quick to blame poor design. But Petroski, known for his masterly explanations of engineering successes and failures, says we must look beyond design to the interdependency of people and machines within complex socioeconomic systems undreamt of by designers.

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.

From the author of the highly praised The Pencil and The Evolution of Useful Things comes another captivating history of the seemingly mundane: the book and its storage.Most of us take for granted that our books are vertical on our shelves with the spines facing out, but Henry Petroski, inveterately curious engineer, didn't. As a result, readers are guided along the astonishing evolution from papyrus scrolls boxed at Alexandria to upright books shelved at the Library of Congress. Unimpeachably researched, enviably written, and charmed with anecdotes from Seneca to Samuel Pepys to a nineteenth-century bibliophile who had to climb over his books to get into bed, The Book on the Bookshelf is indispensable for anyone who loves books.

This book offers an insider's look at the political and cultural dimensions of design, development, and production, and reaffirms Petroski as the master explicator of the principles and processes that turn thoughts into the many things that define our material world.

From ancient Greek temples to twentieth-century towers, engineers have learned more about design from failure than success. The concept of error, according to the author, is central to the design process. As a way of explaining the enduring aspects of engineering design, he relates stories of some of the greatest engineering successes and failures of all time. These case studies, drawn from a wide range of times and places, serve as paradigms of error and judgment in engineering design. By showing how errors were introduced in the design process and how they might be avoided, the book suggests how better quality and reliability might be achieved in designed devices, structures, and systems of all kinds. Clearly written, with striking illustrations, the book will appeal to engineering students, practising engineers, historians of science and technology, and all those interested in learning about the process of design.
