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.
1926: Steganographic analysis of The Safe-Cracker reveals two terabytes of encrypted data.
1927: The first fully electronic television system is achieved by inventor Philo Farnsworth.
1928: Mathematician and crime-fighter Abraham Fraenkel publishes new class of Gnomon algorithm functions based on axiomatic set theory, which he uses to detect and counteract crimes against mathematical constants.
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.
1985: Mathematician George Pólya dies. He made fundamental contributions to combinatorics, number theory, numerical analysis and probability theory.
2017: Signed first edition of Niles Cartouchian and Egon Rhodomunde Confront Gnotilus sells for two million dollars.
2018: Green Tangle 2 voted Picture of the Day by the citizens of New Minneapolis, Canada.
