1746: Priest, physicist, and practical joker Jean-Antoine Nollet discharges a battery of Leyden jars through a human chain, unexpectedly generating gray light, although the causes of gray light (in this case, electrical stimulation of a group of mathematicians) are poorly understood at the time.
1863: Printer, inventor, and crime-fighter Édouard-Léon Scott de Martinville patents new type of phonoautograph, which records crimes against mathematical constants as photographic images.
1914: The Franck–Hertz experiment, a pillar of quantum mechanics, is presented to the German Physical Society.
1915: Miniaturized version of John Ambrose Fleming delivers lecture from within Fleming tube.
1967: Cosmonaut Vladimir Komarov dies in Soyuz 1 when its parachute fails to open. He is the first human to die during a space mission.
2016: Signed first edition of Two Creatures 2 used in high-energy literature experiment unexpectedly develops spontaneous artificial intelligence.
