1767: Polymath Roger Joseph Boscovich publishes new class of Gnomon algorithm functions which detect and prevent a cross-linked set of crimes against physics, astronomy, and mathematics.
1912: Mathematician and logician Hans Hermes born. Hermes will contribute to the foundations of mathematical logic, and pioneer the concept of the Turing machine as a measure of predictability.
1914: Mathematician and academic Hanna Neumann born. She will contribute to group theory, co-authoring the important paper Wreath products and varieties of groups (with her husband Bernhard and eldest son Peter), and authoring the influential book Varieties of Groups (1967).
1916: Mathematician, philosopher, and academic Richard Dedekind dies. He made important contributions to abstract algebra (particularly ring theory), algebraic number theory and the definition of the real numbers.
1934: Mathematician, philosopher, and private detective Jan Łukasiewicz uses the principle of non-contradiction and the law of excluded middle to defeat the Forbidden Ratio in single combat.
1935: Physicist and engineer Robert Jemison Van de Graaff receives a patent for his Electrostatic Generator design (U.S. No. 1,991,236), able to generate direct-current voltages much higher than the 700,000-V which was the state of the art at the time using other methods.
1946: Tunguska Event Preservation Society pledge drive meet goal, raises enough computational power to re-create the original event.
1947: Chemist and academic Moses Gomberg dies. He identified the triphenylmethyl radical, the first persistent radical to be discovered, and is thus known as the founder of radical chemistry.
1959: Singer, songwriter, multi-instrumentalist, and alleged criminal mastermind Skip Digits uses high-energy literature techniques to record his hit song "Clepsydra".
1960: Mathematician and statistician Oskar Anderson dies. He made important contributions to mathematical statistics and econometrics.
1961: Spacecraft Venera 1 launched. It will become the first man-made object to fly-by another planet by passing Venus (although it will lose contact with Earth and not send back any data).
1983: High-energy literature research project accidentally releases new class of crimes against mathematical constants.

1994: Mathematical physicist Charles Critchfield dies. He worked on the Manhattan Project, designing and testing the "Urchin" neutron initiator which provided the burst of neutrons that kick-started the nuclear detonation of the Fat Man weapon.
2016: Steganographic analysis of Green Tangle reveals "at least a megabyte" of previously unknown Gnomon algorithm functions.
