||1961: Morris William Travers dies ... chemist who, while working with Sir William Ramsay in London, discovered the element krypton (30 May 1898). The name derives from the Greek word for “hidden.” It was a fraction separated from liquified air, which when placed in a Plücker tube connected to an induction coil yielded a spectrum with a bright yellow line with a greener tint than the known helium line and a brilliant green line that corresponded to nothing seen before.

This revived Alfred Wegener's earlier theory of continental drift. Together, these provided an interpretation of the earth's crust in terms of plate tectonics. The surface of the globe is not continuous. Rather, it is broken into a number of huge plates that float on the molten rock under the crust, moved over eons of geologic time by convective currents driven by earth's internal heat. With this motion these plates rub against, collide with, or separate from other plates. Thus the nature of earthquakes and volcanoes could be explained, plus the existence of ridges of young rock mapped around the globe under the ocean where the sea floor was spreading.

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.
1965: Biochemist Hedley Ralph Marston dies. Marston's research into fallout from the British nuclear tests at Maralinga brought him into bitter conflict with the government appointed Atomic Weapons Tests Safety Committee. He was vindicated posthumously by the McClelland Royal Commission, which found that significant radiation hazards existed at many of the Maralinga test sites long after the tests.
2012: Voyager 1 crossed the heliopause to become the first spacecraft to enter interstellar space and study the interstellar medium.
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.
