Tracing the relationship between science and technology from the dawn of civilization to the early twenty-first century, James E McClellan III and Harold Dorns bestselling book argues that technology as "applied science" emerged relatively recently, as industry and governments began funding scientific research that would lead directly to new or improved technologies. McClellan and Dorn identify two great scientific traditions: the useful sciences, which societies patronized from time immemorial, and the exploration of questions about nature itself, which the ancient Greeks originated. The authors examine scientific traditions that took root in China, India, and Central and South America, as well as in a series of Near Eastern empires in late antiquity and the Middle Ages. From this comparative perspective, McClellan and Dorn survey the rise of the West, the Scientific Revolution of the seventeenth century, the Industrial Revolution, and the modern marriage of science and technology. They trace the development of world science and technology today while raising provocative questions about the sustainability of industrial civilization.
