The engineering ideas behind key twentieth-century technical innovations, from great dams and highways to the jet engine, the transistor, the microchip, and the computer.

Technology is essential to modern life, yet few of us are technology-literate enough to know much about the engineering that underpins it. In this book, David P. Billington, Jr., offers accessible accounts of the key twentieth-century engineering innovations that brought us into the twenty-first century. Billington examines a series of engineering advances--from Hoover Dam and jet engines to the transistor, the microchip, the computer, and the internet--and explains how they came about and how they work.
