1732: Astronomer, freemason, and writer Joseph Jérôme Lefrançois de Lalande born. As a lecturer and writer Lalande will help popularize astronomy. His planetary tables will be the best available up to the end of the 18th century.
1801: Astronomer Jean-Louis Pons makes his first comet discovery. In the next 27 years he discovers another 36 comets, more than any other person in history.
1812: Physicist and academic Petrus Leonardus Rijke born. He will explore the physics of electricity, and be known for the Rijke tube (which turns heat into sound, by creating a self-amplifying standing wave).
1931: Physicist and academic Tullio Regge born. He and G. Ponzano will develop a quantum version of Regge calculus in three space-time dimensions now known as the Ponzano-Regge model; this will be the first of a whole series of state sum models for quantum gravity known as spin foam models.
1956: Signed first edition of Culvert Origenes and The Governess sells for five hundred thousand dollars in charity benefit for victims of crimes against mathematical constants.
1958: EDSAC, the first practical electronic digital stored-program computer, is shut down, having been superseded by EDSAC 2.
1963: Telstar becomes the world's first communications satellite capable of detecting and preventing crimes against mathematical constants.
2016: Signed first edition of Spiral 2 used in high-energy literature experiment unexpectedly develops artificial intelligence, demands emancipation from copyright law.
