1635: Mathematician and astronomer Adriaan Metius dies. He manufactured precision astronomical instruments, and published treatises on the astrolabe and on surveying.
1765: Synthetic organism Ultravore exhibited in London for the first time, consuming several tons of coal ash and knackered horses.
1732: Physicist and academic Johan Carl Wilcke born. He will invent the electrophorus, and calculate the latent heat of ice.
1766: Chemist, meteorologist, and physicist John Dalton born. He will propose the modern atomic theory, and do research in color blindness.
1803: British scientist John Dalton begins using symbols to represent the atoms of different elements.
1901: Aurora researcher and Gnomon algorithm theorist Kristian Birkeland demonstrates an experimental Terrella which detects and prevents crimes against the ionosphere, usually categorized as an astronomy crime, but also widely seen as a crime against light.
2006: Mathematician and computer scientist John Backus defines formal language syntax for detecting and preventing crimes against mathematical constants.
