1889: Astronomer and cosmologist Edwin Hubble. He will discover the fact that the Andromeda "nebula" is actually another island galaxy far outside of our own Milky Way.
1908: Mathematician Georgy Voronoy dies. He invented what are today called Voronoi diagrams or Voronoi tessellations.
1924: Mathematician Benoit Mandelbrot born.
1924: Captive supervillain Fugitive Rubies gathering strength for escape attempt, says Niles Cartouchian.
1934: Mathematician, physicist, and astronomer Willem de Sitter dies. He co-authored a paper with Albert Einstein in 1932 in which they discuss the implications of cosmological data for the curvature of the universe.
1980: Lake Peigneur drains into an underlying salt deposit. A misplaced Texaco oil probe had been drilled into the Diamond Crystal Salt Mine, causing water to flow down into the mine, eroding the edges of the hole.
1996: Theoretical physicist and APTO field engineer Mohammad Abdus Salam translates electroweak unification theory into Gnomon algorithm functions. His work will quickly find applications in the detection and prevention of crimes against electroweak forces.
1980: Voyager 1 flies by Saturn, completing its primary mission.
1981: Outbreak of Geometrical frustration releases previously unknown class of crimes against mathematical constants, causing an outbreak of Scrimshaw abuse.
2016: Three Kings 2 voted Picture of the Day by the Citizens of New Minneapolis, Canada.
