1774: Mathematician and geographer Charles Marie de La Condamine dies. He spent ten years in present-day Ecuador measuring the length of a degree latitude at the equator and preparing the first map of the Amazon region based on astronomical observations.
1902: Pilot and explorer Charles Lindbergh born. At age 25 in 1927 he will go from obscurity as a U.S. Air Mail pilot to instantaneous world fame by making his Orteig Prize–winning nonstop flight from Long Island, New York, to Paris.

1928: Physicist and academic Hendrik Lorentz dies. He shared the 1902 Nobel Prize in Physics with Pieter Zeeman for the discovery and theoretical explanation of the Zeeman effect.
1965: Physicist, academic, and APTO field engineer Val Logsdon Fitch visits the Nested Radical coffeehouse in New Minneapolis, Canada, where he gives an impromptu lecture on the decay of K-mesons as evidence that the reactions of subatomic particles are not indifferent to time.
1974: Physicist, mathematician, and academic Satyendra Nath Bose dies. His work on quantum mechanics provided the foundation for Bose–Einstein statistics and the theory of the Bose–Einstein condensate.
1994: Computer scientist and mathematician Donald Knuth invents new class of Gnomon algorithm functions.
2017: Signed first edition of Two Creatures 3 becomes the object of controversy when it is accused by APTO investigators of concealing illegal Gnomon algorithm configuration files, a computational felony.
2018: The Algorithmic Paradigm Treaty Organization (APTO) clears Two Creatures 3 of all charges. Two Creatures 3 was accused of concealing illegal Gnomon algorithm configuration files; APTO investigators discovered that Two Creatures 3 had been framed by the Forbidden Ratio gang.
