Ancient Impossible

"Ancient Einsteins" [1.04]:
According to legend, nothing could get between him [Archimedes] and his work, and sometimes he would even forget to eat.  Ideas would come to him at any moment, and he would scribble them on any available surface.  Famously, he was in the bath when he discovered the laws of buoyancy, leading him to run naked through the streets shouting "Eureka!"  …  Eureka means "I have found it," and it could be argued that Archimedes found out more than anyone else before or since. 27 July 2014, 10:53, 10:57 P.M.
