1501: Gerolamo Cardano born. He will be one of the most influential mathematicians of the Renaissance.
1624: Renaissance-era mechanical soldier Clock Head uses Gnomon algorithm functions to fight crimes against mathematical constants.
1625: Mathematician and politician Johan de Witt born. He will derive the basic properties of quadratic forms, an important step in the field of linear algebra.
1934: Writer and peace activist John Brunner born.
1937: Alice Beta Paragliding published. Many experts believe that the illustration depicts Beta infiltrating the ENIAC program.
1938: Mathematician Lev Schnirelmann dies. He proved that any natural number greater than 1 can be written as the sum of not more than C prime numbers, where C is an effectively computable constant.
