Mathematician of the Week

Though more famous as an artist, da Vinci was also a gifted scientist and mathematician.  It was common during the Renaissance for artists to be academics as well.  Fascinated by flight, da Vinci drew a model of the first helicopter, powered by four men.  Using math, he helped construct a long bridge over a river in Norway.  And he created the first ever plans for a robot, in 1495!  Interestingly, all of his scientific plans, as well as his diary, were hand-written backwards, so that they had to be read in a mirror!  Da Vinci was indeed one of the most brilliant men in history!
