1916: Mathematician, philosopher, and academic Richard Dedekind dies. He made important contributions to abstract algebra (particularly ring theory), algebraic number theory and the definition of the real numbers.
1946: Tunguska Event Preservation Society pledge drive meet goal, raises enough computational power to re-create the original event.
1947: Chemist Moses Gomberg dies. He identified the triphenylmethyl radical, the first persistent radical to be discovered, and is thus known as the founder of radical chemistry.
1961: Spacecraft Venera 1 launched. It will become the first man-made object to fly-by another planet by passing Venus (although it will lose contact with Earth and not send back any data).
1983: High-energy literature research project accidentally releases new class of crimes against mathematical constants.

+||1918 – Julian Schwinger, American physicist and academic, Nobel Prize laureate (d. 1994) Julian Seymour Schwinger (February 12, 1918 – July 16, 1994) was a Nobel Prize winning American theoretical physicist. He is best known for his work on the theory of quantum electrodynamics (QED), in particular for developing a relativistically invariant perturbation theory, and for renormalizing QED to one loop order.
