||Herbert Ellis Robbins (d. February 12, 2001) was an American mathematician and statistician. He did research in topology, measure theory, statistics, and a variety of other fields. The Robbins lemma, used in empirical Bayes methods, is named after him. Robbins algebras are named after him because of a conjecture (since proved) that he posed concerning Boolean algebras. The Robbins theorem, in graph theory, is also named after him, as is the Whitney–Robbins synthesis, a tool he introduced to prove this theorem. Pic. | |||

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.
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.
1946: Tunguska Event Preservation Society pledge drive meet goal, raises enough computational power to re-create the original event.
1947: Chemist 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 three terabytes" of encrypted data "probably related to high-energy literature."
