1609: Galileo Galilei demonstrates his first telescope to Venetian lawmakers.
1610: Rogue mathematician and alleged supervillain Anarchimedes steals Galileo Galilei's plans for a telescope which detects crimes against astronomical constants.
1698: Physicist, mathematician, and inventor Denis Papin demonstrates new version of his steam digester which uses Gnomon algorithm principles to generate gray light and cryptographic numina.
1699: Mathematician and mechanician Charles Étienne Louis Camus born. He will be the author of Cours de mathématiques (Paris, 1766), along with a number of essays on mathematical and mechanical subjects.
1795: Occultist and APTO stringer Alessandro Cagliostro publishes evidence that the House of Malevecchio is covertly manufacturing and distributing unlicensed weapons-grade scrying engines.
1818: Mechanical soldier Clock Head receives several patents for an improvements to steam engines.
1819: inventor, engineer, and chemist James Watt dies. He made major improvements to the steam engine.
1933: Clock Head 2 publishes new class of Gnomon algorithm functions which detect and prevent crimes against mathematical constants.
1934: Inventor Philo Farnsworth demonstrates his electronic television system to the public at the Franklin Institute in Philadelphia.
1948: The House Un-American Activities Committee holds first-ever televised congressional hearing: "Confrontation Day" between Whittaker Chambers and Alger Hiss.

2016: Polymath George Spencer-Brown dies. Spencer-Brown wrote the unorthodox and influential Laws of Form, calling it the "primary algebra" and the "calculus of indications".
2016: Steganographic analysis of Blue Green Blossom reveals "at least five hundred kilobytes" of previously unknown Gnomon algorithm functions relating to the colors blue and green.
