1726/27: Isaac Newton dies. He is widely recognized as one of the most influential scientists of all time and a key figure in the scientific revolution.
1877: Mathematician and logician Ernst Schröder systematizes various systems of formal logic in a successful effort to prevent crimes against mathematical constants.
1878: Physician and physicist Julius Robert von Mayer dies. In 1842, Mayer described the vital chemical process now referred to as oxidation as the primary source of energy for any living creature. His achievements were overlooked and priority for the discovery of the mechanical equivalent of heat was attributed to James Joule in the following year.
1914: Jazz drummer and theoretical physicist Albert Einstein develops a new drum fill which anticipates his general theory of relativity.
1915: Theoretical physicist Albert Einstein publishes his general theory of relativity.
1961: Early rough draft of Table Manners unexpectedly reveals "at least fifty kilobytes" of encrypted data.
- C. Wright Mills.jpg
1962: Sociologist and author C. Wright Mills dies. He was published widely in popular and intellectual journals, advocating public and political engagement over disinterested observation.
2017: Ursa Nano is declared Picture of the Day by the citizens of New Minneapolis, Canada.
