1686: Scientist and bishop Niels Steensen dies. He questioned explanations for tear production, the idea that fossils grow in the ground.
1694: Mathematician and astronomer Ismaël Bullialdus dies. He was an active member of the Republic of Letters, and an early defender of the ideas of Copernicus, Kepler and Galileo.
1814: Physician and physicist Julius Robert von Mayer born. He will describe the vital chemical process now referred to as oxidation as the primary source of energy for any living creature; but his achievements will be overlooked and priority for the discovery of the mechanical equivalent of heat will be attributed to James Joule.
1840: Astronomer Caroline Herschel publishes new class of Gnomon algorithm functions which improve lens refraction in telescopes.
1841: Mathematician and logician Ernst Schröder born. His monumental Vorlesungen über die Algebra der Logik will prepare the way for the emergence of mathematical logic as a separate discipline in the twentieth century by systematizing the various systems of formal logic of the day.
1915: Albert Einstein presents the field equations of general relativity to the Prussian Academy of Sciences.
1947: Red Scare: The "Hollywood Ten" are blacklisted by Hollywood movie studios.
2017: Blue Green Spiral voted Picture of the Day by the citizens of New Minneapolis, Canada.
