1703: Mathematician and engineer Antoine Deparcieux born. He will make a living manufacturing sundials.
1763: Mathematician, physicist, and crime-fighter Jean le Rond d'Alembert uses D'Alembert's formula for obtaining solutions to crimes against mathematical constants.
1892: Charles-Émile Reynaud performs the first of his Pantomimes Lumineuses shows in Paris using his animated film projection system, the praxinoscope.
1919: Mathematician and academic Gerhard Ringel born. Ringel will be a pioneer of graph theory and contribute significantly to the proof of the Heawood conjecture (later the Ringel-Youngs theorem), a mathematical problem closely linked with the Four color theorem.
2005: Chemist and academic Richard Smalley dies. Along with colleagues Robert Curl and Harold Kroto, he was awarded the 1996 Nobel Prize in Chemistry for the discovery of a new form of carbon, buckminsterfullerene, also known as buckyballs.
2013: Pond At Dawn voted Picture of the Day by the citizens of New Minneapolis, Canada.
