An eminent engineer and historian tackles one of the most elemental aspects of life: how we experience and utilize physical force
Force explores how humans interact with the material world in the course of their everyday activities. This book for general audiences also considers the significance of force in shaping societies and cultures.

Celebrated author Henry Petroski delves into the ongoing physical interaction between people and things that enables them to stay put or causes them to move. He explores the range of daily human experience whereby we feel the sensations of push and pull, resistance and assistance. The book is also about metaphorical force, which manifests itself as pressure and relief, achievement and defeat.

Petroski draws from a variety of disciplines to make the case that force-represented especially by our sense of touch-is a unifying principle that pervades our lives. In the wake of a prolonged global pandemic that increasingly cautioned us about contact with the physical world, Petroski offers a new perspective on the importance of the sensation and power of touch.

From the acclaimed author of The Pencil and To Engineer Is Human, The Essential Engineer is an eye-opening exploration of the ways in which science and engineering must work together to address our world’s most pressing issues, from dealing with climate change and the prevention of natural disasters to the development of efficient automobiles and the search for renewable energy sources. While the scientist may identify problems, it falls to the engineer to solve them. It is the inherent practicality of engineering, which takes into account structural, economic, environmental, and other factors that science often does not consider, that makes engineering vital to answering our most urgent concerns.

Henry Petroski takes us inside the research, development, and debates surrounding the most critical challenges of our time, exploring the feasibility of biofuels, the progress of battery-operated cars, and the question of nuclear power. He gives us an in-depth investigation of the various options for renewable energy—among them solar, wind, tidal, and ethanol—explaining the benefits and risks of each. Will windmills soon populate our landscape the way they did in previous centuries? Will synthetic trees, said to be more efficient at absorbing harmful carbon dioxide than real trees, soon dot our prairies? Will we construct a “sunshade” in outer space to protect ourselves from dangerous rays? In many cases, the technology already exists. What’s needed is not so much invention as engineering.

Just as the great achievements of centuries past—the steamship, the airplane, the moon landing—once seemed beyond reach, the solutions to the twenty-first century’s problems await only a similar coordination of science and engineering. Eloquently reasoned and written, The Essential Engineer identifies and illuminates these problems—and, above all, sets out a course for putting ideas into action.

How did a simple design error cause one of the great disasters of the 1980s-the collapse of the walkways at the Kansas City Hyatt Regency Hotel? What made the graceful and innovative Tacoma Narrows Bridge twist apart in a mild wind in 1940? How did an oversized waterlily inspire the magnificent Crystal Palace, the crowning achievement of Victorian architecture and engineering? These are some of the failures and successes that Henry Petroski, author of the acclaimed The Pencil, examines in this engaging, wonderfully literate book. More than a series of fascinating case studies, To Engineer Is Human is a work that looks at our deepest notions of progress and perfection, tracing the fine connection between the quantifiable realm of science and the chaotic realities of everyday life.
