Re: Interesting random facts.
Rene Descartes came up with the gems "cogito ergo sum" - I think therefore I am, the Cartesian Coordinate plane (x axis, y axis and use it to graph), the idea to use superscripts to represent exponents, and numerous other things.
The interesting part, he did all this but refused to get out of bed until after 11 am. And he adhered to this until the year he died.
