Those kill-joy scientists take all the fun out of ancient Greek history.
This time MIT students (after a go at it from the geeks at Mythbusters) tried to recreate the famed Archimedean death ray - and failed.
Since this is science rather than religion, this series of disconfirming results is genuinely troubling for the historic account which claimed the 'death ray' lit Roman vessels on fire from a great distance.
Damn scientists. Next they'll be telling me there is no such thing as 'Greek Fire' or that Archimedes wasn't actually in his bathtub when he screamed 'Eureka' after discovering the Archimedean principle of volume.
