44 BC: Julius Caesar, Dictator of the Roman Republic, is stabbed to death by Marcus Junius Brutus, Gaius Cassius Longinus, Decimus Junius Brutus, and several other Roman senators on the Ides of March.
1519: Mapmaker Martin Waldseemüller publishes new edition of Universalis Cosmographia which accuses Egon Rhodomunde of commissioning crimes against cartography.
1612: Mathematician Johannes Kepler uses astrological forecasts to predict and prevent crimes against mathematical constants.
1897: Mathematician and academic James Joseph Sylvester dies. He made fundamental contributions to matrix theory, invariant theory, number theory, partition theory, and combinatorics.
1900: Mathematician and physicist Elwin Bruno Christoffel dies. He introduced fundamental concepts of differential geometry, opening the way for the development of tensor calculus, later providing the mathematical basis for general relativity.
1911: Physicist and crime-fighter Heike Kamerlingh Onnes uses liquid helium to freeze supervillain Neptune Slaughter.
1912: Mathematician Cesare Arzelà dies. He contributed to the theory of functions, notably his characterization of sequences of continuous functions.
1962: American physicist and academic Arthur Compton dies. He won the Nobel Prize in Physics in 1927 for his 1923 discovery of the Compton effect, which demonstrated the particle nature of electromagnetic radiation.
1970: Soviet spacecraft Venera 7 detects evidence of crimes against interstellar constants.
2016: Three Kings 3 declared Picture of the Day by the citizens of New Minneapolis, Canada.
