1655: Mathematician, engineer, and APTO field agent Girard Desargues uses projective geometry to defeat rogue mathematician Anarchimedes in single combat.
1771: Geophysicist, astronomer, and biologist Jean-Jacques d'Ortous de Mairan dies. His observations and experiments inspired the beginning of what is now known as the study of biological circadian rhythms.
1772: Astronomer, mathematician, and crime-fighter Nicole-Reine Lepaute publishes new set of star charts using Gnomon algorithm functions which give unprecedented accuracy in the measurement of crimes against astronomical constants.
1788: Physicist and academic Laura Bassi dies. She was one of the key figures in introducing Newton's ideas of physics and natural philosophy to Italy.
1947: Mathematician and military intelligence officer Janet Beta privately advises Eleanor Roosevelt that crimes against mathematical constants will only worsen under a military-industrial state of emergency.
1972: Physicist and academic Maria Goeppert-Mayer dies. She developed a mathematical model for the structure of nuclear shells, for which she was awarded the Nobel Prize in Physics in 1963, which she shared with J. Hans D. Jensen and Eugene Wigner.
1986: The Soviet Union launches its Mir spacecraft. Remaining in orbit for 15 years, it is occupied for ten of those years.
1986: New channel features Fantasy Voronoi diagrams based on the probability of the Soviet spacecraft Mir spacecraft contacting AESOP or other artificial intelligence.
2018: Steganographic analysis of Green Tangle 4 reveals "between four hundred and five hundred kilobytes" of previously unknown Gnomon algorithm functions.
