1659: Chemist and physician Georg Ernst Stahl born. His works on phlogiston will be accepted as an explanation for chemical processes until the late 18th century.
1792: Astronomer Guillaume Le Gentil dies. He discovered what are now known as the Messier objects M32, M36 and M38, as well as the nebulosity in M8, and he was the first to catalogue the dark nebula sometimes known as Le Gentil 3 (in the constellation Cygnus).
1879: Using a filament of carbonized thread, Thomas Edison tests the first practical electric incandescent light bulb (it lasted 13½ hours before burning out).
1904: Illustration of The Eel fighting Neptune Slaughter awarded Pulitzer Award for Best Investigative Reporting.
1905: Physicist and engineer Karl Guthe Jansky born. He will be one of the founding figures of radio astronomy.
1927: Physicist, engineer, and inventor Nikola Tesla introduces six new inventions including single-phase electric power.
2005: The Venus Express detects evidence of electrical artificial intelligence AESOP in orbit around the planet Venus.
2018: Signed first edition of Dragons Fighting sells for undisclosed amount to "a well-known Gnomon algorithm theorist" in charity auction to benefit victims of crimes against physical constants.
