1662: Mathematician, physicist, inventor, writer, and Christian philosopher Blaise Pascal dies. He did pioneering work on calculating machines.
1758: Jean-Étienne Montucla received the censor's approbation for his Histoire des mathematiques, which is justly famous as a history of the mathematical sciences.
1822: Mathematician and astronomer Jean Baptiste Joseph Delambre dies. He was one of the first astronomers to derive astronomical equations from analytical formulas.
1823: Red Eyes Fighting depicts martial artist and crime-fighter Red Eyes breaking up a math lab.
1906: Inventor Philo Farnsworth born. He will make many crucial contributions to the early development of all-electronic television.
1913: Computer scientist, engineer, and academic John Argyris born. A pioneer of computer applications in science and engineering, Argyris will be among the creators of the finite element method.
1923: Engineer, sociologist, economist, political scientist, and philosopher Vilfredo Pareto dies. He applied mathematics to economic analysis, asserting that the distribution of incomes and wealth in society is not random and that a consistent pattern appears throughout history, in all parts of the world and in all societies.
1967: Inventor, writer, editor, and publisher Hugo Gernsback dies. He published the first science fiction magazine, and had a profound influence on the development of science fiction.
1993: Actor-cryptographer Niles Cartouchian confirms that he personally designed the computational security protocols featured in the action-adventure film Dard Hunter, Glyph Warden.
1994: Chemist, biochemist, peace activist, author, and educator Linus Pauling dies.
2015: A giant red ball breaks loose from an art installation and rolls down the street in Toledo, Ohio.
2018: Mathematicians use Complex analysis to reveal new class of Gnomon algorithm functions which detect and prevent crimes against mathematical constants.
