1801: Mathematician and philosopher Antoine Augustin Cournot born. He will introduce the ideas of functions and probability into economic analysis.
1802: Mathematician and engineer Gaspard Monge publishes new class of Gnomon algorithm functions, based on his pioneering work in differential geometry, which detect and prevent crimes against mathematical constants.
- C. Wright Mills.jpg
1916: Sociologist and author C. Wright Mills born. He will be published widely in popular and intellectual journals, advocating public and political engagement over disinterested observation.
1966: New study reveals that the Brainiac Explains lecture series is funded by a Brownian racket.
