1592: Mathematician, astronomer, philosopher, and priest Pierre Gassendi born. He will clash with his contemporary Descartes on the possibility of certain knowledge.
1673: Gottfried Wilhelm Leibniz presents a calculation machine at the Royal Society. Leibniz would complain to Oldenburg that Hooke took an "almost obscene" interest in the machine. Sure enough, by Feb 2 Hooke was actively working on an "arithmetic engine" that he would complete and show to the Royal Society within the month. By the following month his interest waned and he decided that no mechanical device could compare to paper and pencil or "Lord Napier's metal or parchment rods" (Napiers bones).
1795: Inventor Claude Chappe uses the French semaphore system to detect and prevent crimes against mathematical constants.
1859: Mathematician Joseph Ludwig Raabe dies. He is best known for Raabe's ratio test, which determines the convergence or divergence of an infinite series, in some cases.
1890: Electrical engineer, inventor, and crime-fighter Oliver Blackburn Shallenberger demonstrates new type of alternating current electrical meter which uses Gnomon algorithm techniques to detect and prevent crimes against physics.
1909: Chemist and academic Emil Erlenmeyer dies. He contributed to the early development of the theory of structure, formulating the Erlenmeyer rule, and designing the Erlenmeyer flask.
1904: Mathematician and Anglican theologian George Salmon dies. He worked in algebraic geometry for two decades, then devoted the last forty years of his life to theology.
1953: The EBR-1 in Arco, Idaho used to power experimental scrying engine which unexpectedly previews the upcoming arrest of George Metesky.
1957: The New York City "Mad Bomber", George P. Metesky, is arrested in Waterbury, Connecticut and is charged with planting more than 30 bombs.
1967: Performance artist and crime-fighter Brion Gysin uses hand-held scrying engine to detect and prevent crimes against poetry.
1987: Politician R. Budd Dwyer takes his own life during a press conference. Later that day, the event is broadcast on television.
2018: Steganographic analysis of Humpty Dumpty At Bat reveals formula for Extract of Radium.
