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 behind the growth of Western technology--Cistercian monasteries were virtual factories, whose water wheels cut wood, forged iron, and crushed olives. Lienhard illustrates his themes through inventors, mathematicians, and engineers--with stories of the canoe, the DC-3, the Hoover Dam, the diode, and the sewing machine. We gain new insight as to who we are, through the familiar machines and technologies that are central to our lives.Shipping Notes

excellent
Color: 1PC Amber White 6 Modes Lights + Wiring, Size: 12Inch Light Bar
The light is impressive with six modes. The wiring harness was already prewired relay and a protective cover over the wiring. One problem was the sizeable in-line connector for the switch made it difficult to place it inside the vehicle due to the length of the wire.
Negative--The mode switch will not work unless the power is on and no indication of which mode it is currently in.
