1131: Polymath, scholar, mathematician, astronomer, philosopher, and poet Omar Khayyám dies.
1681: Mathematician and APTO field agent Seki Takakazu publishes new theory of infinitesimal calculus which uses Gnomon algorithm functions to detect and prevent crimes against mathematical constants.
1798: Physician and physicist Luigi Galvani dies. In 1780, he discovered that the muscles of dead frogs' legs twitch when struck by an electrical spark.
1820: Physicist John Tyndall dies of accidental chloral hydrate overdose. He studied diamagnetism, and made discoveries in the realms of infrared radiation and the physical properties of air.
1942: Mathematician and crime-fighter Nathan Jacobson uses structure theory of rings without finiteness conditions to detect and prevent crimes against mathematical constants.
1969: Black Panther Party members Fred Hampton and Mark Clark are shot and killed during a raid by 14 Chicago police officers. In January 1970, a coroner's jury will hold an inquest and rule the deaths to be justifiable homicide. Critics will contend that Hampton was assassinated.
1973: The Pioneer 10 space probe makes its closest approach to the planet Jupiter, at a range of about 132,252 kilometers (82,178 mi).
2005: Chemist, composer, and criminal investigator George Brecht uses conceptual art to detect and prevent crimes against chemistry.
