Apparently not quite busy enough dealing with midterm elections and finishing up Freedom, President Obama will appear on the December 8 episode of the Discovery Channel’s science show Mythbusters. In the episode, Obama asks the hosts to figure out whether the Greek mathematician Archimedes could actually have set fire to a fleet of Roman ships using only sun-reflecting mirrors. (Guess the episode where they prove Obama was born in Hawaii will have to wait for next season.) [Dot Earth/NYT]
