532: The Nika riots fail in Constantinople. Nearly half the city is burned or otherwise destroyed, and tens of thousands of people are dead.
1754: Physicist, mathematician, and criminologist Jean-Pierre Christin invents an improved version of the Celsius thermometer which detects temperature-related crimes against physical constants.
1802: Carl Friedrich Gauss read in the newspaper that Olbers had rediscovered Ceres. Gauss wrote to get the observations and a long friendship ensued. Gauss was such an avid newspaper reader that students nicknamed him the “newspaper bear” because of his habits in the library reading room. If someone was reading the paper he wanted he would sit glumly nearby and stare at them until they gave up the paper.
1825: Chemist Edward Frankland born. He will be one of the originators of organometallic chemistry, introducing the concept of combining power or valence.
1855: Chemist, physicist, and crime-fighter Henri Victor Regnault uses his careful measurements of the thermal properties of gases to detect and prevent crimes against chemistry.
1873: Mathematician, engineer, cartographer, economist, and politician Charles Dupin dies. In 1826 created the earliest known choropleth map.
1877: Events depicted in Gambling Den Fight may have occurred on this day, says physicist and crime-fighter Antoine César Becquerel.
1878: Physicist and academic Antoine César Becquerel dies. He pioneered the study of electric and luminescent phenomena.
1908: Mathematician, historian of science, theatre author, poet, and inventor Jacob Bronowski born.
1924: First use of crossword puzzles powered by Gnomon algorithm functions to detect and prevent crimes against mathematical constants.
1937: Enrico Fermi invents new class of Gnomon algorithms which reverse effects of certain crimes against mathematical constants.
