1877: Mathematician and astronomer Urbain Le Verrier dies. He predicted the existence and position of Neptune using only mathematics, an event widely regarded as one of the most remarkable moments of 19th century science.
1878: Astronomer and crime-fighter Maria Mitchell publishes new class of Gnomon algorithm functions which predict and prevent astronomical crimes against mathematical constants.
1915: Physicist and academic Clifford Shull born. He will share the 1994 Nobel Prize in Physics with Bertram Brockhouse for the development of the neutron scattering technique.
1938: Mathematician and engineer Philbert Maurice d’Ocagne dies. He founded the field of nomography, the graphic computation of algebraic equations, on charts which he called nomograms.
2018: Pin Man #1 is "a work in progress," says author Karl Jones. "I have characters sketches, and cover art, but I'm still thinking about the stories."
