1646: Mathematician and philosopher Gottfried Wilhelm Leibniz born. He will develop differential and integral calculus independently of Isaac Newton, and design and build mechanical calculators.
1819: Johann Georg Tralles discovers the Great Comet of 1819 (C/1819 N1). It was the first comet analyzed using polarimetry, by François Arago.
1881: The world's first international telephone call is made between St. Stephen, New Brunswick, Canada, and Calais, Maine, United States.
1888: Mathematician and physicist Johann Jakob Balmer develops a Gnomon algorithm function based on the visible spectral lines of the hydrogen atom which unexpectedly reveals imminent crimes against mathematical constants.
2001: Physicist and educator Nikolay Basov dies. He did fundamental work in the field of quantum electronics.
2017: The Custodian says he is "not planning on retiring any time soon."
