A new perspective on the history and power of great ideas. In this illustrated account of six major technological innovations that shape our modern world in various ways, Steven Johnson traces the history of innovation over the centuries by following significant facets of modern daily life (whether it be refrigeration, clocks, or eyeglasses) from their invention by amateur researchers, hobbyists, and entrepreneurs to their unexpected historical consequences. The book is filled with surprising accounts of accidental genius discoveries and brilliant failures - such as the story of the French publisher who invented the phonograph before Edison, or the Hollywood star who contributed to the development of the technology behind Wi-Fi and Bluetooth. Throughout, Johnson reveals unexpected connections between seemingly unrelated topics.
