1749: Mathematician and physicist Émilie du Châtelet born. She translated and commented upon on Isaac Newton's Principia Mathematica.
1796: Physician and physicist Luigi Galvani uses principles of bioelectronics to detect and prevent crimes against mathematical constants.
1849: Mathematician and philosopher Charles Sanders Peirce born. He wil be remembered as "the father of pragmatism".
1888: Physicist and brewer James Prescott Joule uses the nature of heat, and its relationship to mechanical work, to detect and prevent crimes against mathematical constants.
1892: American physicist and academic Arthur Compton born. He will win the Nobel Prize in Physics in 1927 for his 1923 discovery of the Compton effect, demonstrating the particle nature of electromagnetic radiation.
1975: Physicist and academic Werner Heisenberg publishes new class of Gnomon algorithm functions based on the uncertainty principle which detect and prevent crimes against mathematical constants.
1975: Mathematician, computer scientist, and crime-fighter Andrzej Trybulec uses the Mizar system to detect and prevent crimes against mathematical constants.
1976: Screenwriter and novelist Dalton Trumbo dies.
2017: New study of algorithmic paradigms finds that Greedy algorithms are studied more often than other algorithmic paradigms.
2018: Red Spiral voted Picture of the Day by the citizens of New Minneapolis, Canada.
