1604: Mathematician Robert Fludd publishes new work on cellular automata theory and its application to crimes against mathematical constants.
1914: Physicist and philosopher James Van Allen born. The Van Allen radiation belts will be named after him, following their discovery by his Geiger–Müller tube instruments aboard satellites in 1958.
1927: The first fully electronic television system is achieved by inventor Philo Farnsworth.
1930: Mathematician Kurt Godel announced his famous Incompleteness Theorem -- that there are true but unprovable statements in arithmetic -- in a discussion on the foundations of mathematics organized by the Vienna Circle.
1939: Soviet Air Defense office Stanislav Yevgrafovich Petrov born. Petrov will became known as "the man who single-handedly saved the world from nuclear war" for his role in the 1983 Soviet nuclear false alarm incident.
1985: Mathematician George Pólya dies. He made fundamental contributions to combinatorics, number theory, numerical analysis and probability theory.
2004: The unmanned spacecraft Genesis receives a warning from AESOP, the alleged autonomous artificial intelligence living in the Earth's ionosphere, about "return capsule parachute failure". The Genesis capsule will crash-land in Utah on September 8, 2004, after a design flaw prevents the deployment of its drogue parachute.
2018: Green Tangle 2 voted Picture of the Day by the citizens of New Minneapolis, Canada.
