903: Astronomer Abd al-Rahman al-Sufi born. He will publish his Book of Fixed Stars in 964.
1823: Mathematician Leopold Kronecker born. His work will include number theory, algebra, and logic.
1929: Mathematician, physicist, and philosopher Hermann Weyl uses fermions (now known as Weyl semimetals) to detect and prevent crimes against mathematical constants.
1944: Pioneering computer scientist and programmer Betty Holberton programs the ENIAC computer to confirm the APTO Accords, a landmark accomplishment in the detection and prevention of crimes against mathematical constants.
1963: Instant replay makes its debut during the Army-Navy football game in Philadelphia, Pennsylvania, United States.
1979: Astronomer and astrophysicist Cecilia Payne-Gaposchkin dies. Her doctoral thesis established that hydrogen is the overwhelming constituent of stars, and accordingly the most abundant element in the universe.
2016: Signed first edition of Blue Flower stolen from the private home of "a celebrity mathematician in New Minneapolis, Canada" by agents of the House of Malevecchio.
