Millions of people have listened to John H. Lienhard's radio program "The Engines of Our Ingenuity." In this fascinating book, Lienhard gathers his reflections on the nature of technology, culture, and human inventiveness. The book brims with insightful observations. Lienhard writes that the history of technology is a history of us--we are the machines we create. Thus farming dramatically changed the rhythms of human life and redirected history. War seldom fuels invention--radar, jets, and the digital computer all emerged before World War II began. And the medieval Church was a driving force...

In How Invention Begins, Lienhard reconciles the ends of invention with the individual leaps upon which they are built, illuminating the vast web of individual inspirations that lie behind whole technologies. He traces, for instance, the way in which thousands of people applied their combined inventive genius to airplanes, railroad engines, and automobiles. As he does so, it becomes clear that a collective desire, an upwelling of fascination, a spirit of the times--a Zeitgeist--laid its hold upon inventors. The thing they all sought to create was speed itself. Likewise, Lienhard shows that...

Engineers face many challenges in systems design and research. Modeling and Approximation in Heat Transfer describes the approach to engineering solutions through simplified modeling of the most important physical features and approximating their behavior. Systematic discussion of how modeling and associated synthesis can be carried out is included - in engineering practice, these steps very often precede mathematical analysis or the need for precise results.

Modern is a word much used, but hard to pin down. In Inventing Modern, John H. Lienhard uses that word to capture the furious rush of newness in the first half of 20th-century America. An unexpected world emerges from under the more familiar Modern. Beyond the airplanes, radios, art deco, skyscrapers, Fritz Lang's Metropolis, Buck Rogers, the culture of the open road--Burma Shave, Kerouac, and White Castles--lie driving forces that set this account of Modern apart.
One force, says Lienhard, was a new concept of boyhood--the risk-taking, hands-on savage...
