George Dyson is an author and historian whose publications broadly cover the evolution of technology in relation to the physical environment and the direction of society. The development of the Aleutian kayak, its adaptation by Russians in the 18th and 19th centuries, and his own redevelopment of the craft in the 1970s was chronicled in his Baidarka of 1986. His 1997 Darwin Among the Machines (“the last book about the Internet written without the Internet”) explored the history and prehistory of digital computing and telecommunications as a manifestation of the convergent destiny of organisms and machines. Project Orion, published in 2002, assembled first-person interviews and recently declassified documents to tell the story of a path not taken into space: a nuclear-powered spaceship whose objective was to land a party of 100 people on Mars four years before we landed two people on the Moon. Turing’s Cathedral, published in 2012, illuminated the transition from numbers that mean things to numbers that do things in the aftermath of World War II. Dyson’s current project, Analogia, is a semi-autobiographical reflection on how analog computation is re-establishing control over the digital world.
