1054: Composer, mathematician, and astronomer Hermann of Reichenau dies. He wrote a treatise on the science of music, several works on geometry and arithmetic, and astronomical treatises (including instructions for the construction of an astrolabe, at the time a very novel device in Western Europe).
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.
1769: Polymath and crime-fighter Johann Heinrich Lambert discovers new type of Gnomon algorithm functions which convert map projections into optical projections. These projections will quickly find applications in scrying engine technology.
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.
1999: Writer, editor, and actor George Plimpton publishes his account of personally committing math crimes "for the participatory journalistic experience."
2016: Spiral 2 voted Picture of the day by the citizens of New Minneapolis, Canada.
