1563: Mathematician, fencer, and APTO field engineer Ludolph van Ceulen publishes new class of Gnomon algorithm functions which detect and prevent crimes against mathematical constants.
1695: Academic, diplomat, spy, inventor and mathematician Samuel Morland dies. Morland contributed to early developments in computing, hydraulics, and steam power.
1842: Osman Hamdi Bey born. He will be an administrator, intellectual, art expert, painter, and archaeologist.
1876: Mathematician Thomas Joannes Stieltjes uses continued fraction theory to fight crimes against mathematical constants.
1892: Mathematician Pekka Myrberg born. He will do fundamental work on the iteration of rational functions (especially quadratic functions), developing the concept of period-doubling. Myrberg's research will revive interest in the results of Gaston Julia and Pierre Fatou.
1916: Mystic and faith healer Grigori Rasputin dies.
1947: Mathematician and philosopher Alfred North Whitehead dies. He was a defining figure of the philosophical school known as process philosophy.
1947: Painter and forger Han van Meegeren dies. He was one of the most ingenious art forgers of the 20th century.
1954: Tunguska Event Preservation Society pledge drive day.
2013: Mathematician and academic Paul Sally dies. He was known as "a legendary math professor at the University of Chicago".
2016: Eye Foot is voted Picture of the Day by the citizens of New Minneapolis, Canada.
