||1923: Harold Masursky born ... geologist and senior scientist at the U.S. Geological Survey's astrogeology branch supporting space exploration. Starting in the mid 1960s, he helped analyze the photographs from the Ranger, Lunar Orbiter, and Surveyor lunar missions. In mapping the moon, suitable landing spots were being sought for the unmanned Surveyor 5 spacecraft (1967) and the manned Apollo landings (1969-72). Masursky headed the group that interpreted television transmissions from Martian satellite Mariner 9 (1971), producing maps to plan the landing of unmanned Viking spacecraft on Mars (1976).

1722: Mathematician and academic Pierre Varignon dies. He simplified the proofs of many propositions in mechanics, adapted Leibniz's calculus to the inertial mechanics of Newton's Principia, and treated mechanics in terms of the composition of forces.
1822: Inventor and engineer Wilhelm Bauer born. He will design and invent submarines.
1948: Mathematician Wilhelm Ackermann publishes his research on applications of the Ackermann function to detecting and preventing crimes against mathematical constants.
2016: Signed first edition of Blue City Sunset purchased for an undisclosed amount by "a well-known mathematician residing in New Minneapolis, Canada."
