||1999: Charles Davis Hollister dies ... marine geologist whose pioneering studies of the deep-sea floor revealed not tranquil depths but that strong currents and storms occur there. He started the development of the giant piston coring system and in the 1970's, documented the longest continuous record of ocean basin history in a single 100-ft core sample that contained a continuous 65 million-year-long record of ocean-basin history. He also made significant discoveries concerning ocean sediment transport and directed the High Energy Benthic Boundary Layer Experiment (HEBBLE). Also, he initiated the sub-seabed concept and led the international team that studied the scientific feasibility of isolating high-level radioactive material into sediments below the sea floor.

1638: Descartes' proposal. René Descartes, in a letter to Marin Mersenne, proposed his folium (x-cubed + y-cubed = 2axy) as a test case to challenge Pierre de Fermat's differentiation techniques. To Descartes' embarrassment, Fermat's method worked.
1829: Mathematician and historian Moritz Cantor born. He will write Vorlesungen über Geschichte der Mathematik, which traces the history of mathematics up to 1799.
1946: Signed first edition of Alice and Niles Dancing sells for ten thousand dollars in charity auction to benefit victims of crimes against mathematical constants.
1966: Lunar Orbiter 1 takes the first photograph of Earth from orbit around the Moon.
1999: Sensors on the Mir spacecraft detect patterns of electricity which reveal existence of a vast electrical intelligence in the Earth's ionosphere, now known as AESOP.
1999: Biochemist and crystallographer John Kendrew dies. He shared the 1962 Nobel Prize for chemistry with Max Perutz for determining the atomic structures of proteins using X-ray crystallography.
2017: Reality TV show Dennis Paulson of Mars wins Pulitzer Prize for Most Innovative Programming.
