Galileo, Leonardo, Newton, and Tesla revered him: Archimedes of Syracuse--an engineer who single-handedly defied the world's most powerful army and a mathematician who knew more in 212 BCE than all of Europe would know for the next seventeen centuries. In this bold reimagining, modern polymath Nicholas Nicastro shines a new light on Archimedes' life and work. Far from the aloof, physically inept figure of historical myth, Archimedes is revealed to be an ambitious, combative, and fiercely competitive man. A genius who challenged an empire, Archimedes emerges in this book as the world's first fully modern scientist--millennia before his intellectual descendants transformed our world.
