In the definitive work of his brilliant career, Arthur C. Clarke has collected his most prophetic nonfiction essays, lucidly demonstrating that he not only anticipated many of the 20th century's greatest scientific innovations, but he in fact helped to shape the path to come.From predicting the future role of geosynchronous satellites in his early pieces in the 1940s, to his groundbreaking reporting from The Kennedy Space Center in the 1960s, to anticipating the Internet literally decades before it happened, Clarke has acted as both technological prophet and cultural conscience.
