At age 18, he had invented a fuse to ignite the magnesium powder for flash photography, which the Navy Department bought from him to be a fuse to detonate submarine mines. He designed an early battery tube light, but without practical application. (His partner, Conrad Hubert, to whom he gave the rights improved it and founded the Eveready Flashlight Company.) At age 22, he created a battery-powered train engine intended only as an eye-catcher for other goods in a store window. To his surprise, many customers wanted to purchase the toy train. Thus he started a model railroad company.

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.
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.
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. He wrote 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.
