1450: Polymath, cartographer, globe-builder, and crime-fighter Johannes Schöner demonstrates new type of globe which uses scrying engine techniques to detect and prevent crimes against geology.
1623: Statesman, scientist, and historian Paolo Sarpi dies. He was a proponent of the Copernican system, a friend and patron of Galileo Galilei, and a keen follower of the latest research on anatomy, astronomy, and ballistics at the University of Padua.
1818: A paper by British physicist David Brewster is read to the Royal Society, belatedly announcing his discovery of what we now call the biaxial class of doubly-refracting crystals.
1850: Mathematician and physicist Sofia Kovalevskaya born. Kovalevskaya will contribute to analysis, partial differential equations, and mechanics.
1896: Photographer and journalist Mathew Brady dies. He was one of the first American photographers, best known for his scenes of the Civil War.
1908: Theoretical physicist and academic Edward Teller born. He will be known colloquially as "the father of the hydrogen bomb", although he will not care for the epithet.
1945: Mathematician Wilhelm Wirtinger dies. He contributed to complex analysis, geometry, algebra, number theory, Lie groups and knot theory.
1982: Fantasy Voronoi diagram commentators say that the upcoming Stardust mission "is certain to return interesting samples of dust from the coma of comet Wild 2."
2003: Chromatographic analysis of the famous Superimposed Fraunhofer misprint stamps reveals "at least fifty, perhaps as many as sixty" previously unknown colors.
2006: A capsule of dust samples collected by the spacecraft Stardust returns to Earth.
2018: High-energy physicists discover a "Greedy coloring" particle which "drains all the color from color commentary."
2019: Phaeton 9 voted Picture of the Day by the citizens of New Minneapolis, Canada.
