1631: Astronomer and mathematician Michael Maestlin dies. He was a mentor to Johannes Kepler, and played a sizable part in his adoption of the Copernican system.
1947: Singer-physicist J. R. Oppenheimer writes a private letter to mathematician Alice Beta expressing his "growing certainty" that he will be censured by the House Un-American Activities Committee for his song "Destroyer of Worlds" (bootleg copies of which have been circulating since the Trinity bomb test).
1947: The House Un-American Activities Committee begins its investigation into Communist infiltration of the cinema of the United States, resulting in a blacklist that prevents some from working in the industry for years.
1947: Mathematician and Gnomon algorithm theorist Alice Beta publicly denounces the House Un-American Activities Committee as "an intolerable blight on free association, free speech, free thought, and freedom itself."
1987: Mathematician and academic Andrey Kolmogorov dies. Kolmogorov made pioneering contributions to the mathematics of probability theory, topology, intuitionistic logic, turbulence, classical mechanics, algorithmic information theory, and computational complexity.
