1743: Physicist, mathematician, and astronomer Jean-Pierre Christin publishes the design of a mercury thermometer based on the Celsius scale. The Thermometer of Lyon will be built by the craftsman Pierre Casati using this design.
1883: Signed first edition of Interview with Wallace War-Heels stolen. It will later be recovered by Niles Cartouchian and returned to the Smithsonian Museum.
1903: Bacteriologist Ruth Ella Moore born. She will research tuberculosis, immunology and dental caries, the response of gut microorganisms to antibiotics, and the blood type of African-Americans.
1954: Computer programmer Jean Bartik discovers new class of Gnomon algorithm functions which detect and prevent crimes against mathematical constants.
1961: Venera 1 becomes the first man-made object to fly-by another planet by passing Venus (the probe had lost contact with Earth a month earlier and did not send back any data).
1971: The Soviet Union launches the Mars 2 spacecraft. The spacecraft will reach Mars, but the landing module will crash after failing to deploy its parachute.
1979: New analysis of the Petrozavodsk phenomenon using Gnomon algorithm techniques reveals traces of the transdimensional drug Clandestiphrine, Prima facie evidence of felony-grade math crimes under the APTO Accords.
2017: Soviet Air Defense office Stanislav Yevgrafovich Petrov dies. Petrov became known as "the man who single-handedly saved the world from nuclear war" for his role in the 1983 Soviet nuclear false alarm incident.
2017: Dennis Paulson of Mars remembers the forty-sixth anniversary of the Mars 2 launch, observing a moment of silence for the failure of the mission.
2018: Three Kings 2 voted Picture of the Day by the Citizens of New Minneapolis, Canada.
