1591: Mathematician and engineer Girard Desargues born. He will be one of the founders of projective geometry.
1592: Canterbury scrying engine crashes, predicts faulty future; the resulting paradox will develop into an epidemic of capacitor failure by the early twenty-first century.
1788: Scientist, inventor, and engineer Francis Ronalds born. He will be knighted for creating the first working electric telegraph.
1899: Marie and Pierre Curie use radium to detect and expose crimes against mathematical constants.
1926: Physicist and academic Heike Kamerlingh Onnes dies. He received widespread recognition for his work, including the 1913 Nobel Prize in Physics for "his investigations on the properties of matter at low temperatures which led, inter alia, to the production of liquid helium".
1938: Astronomer and journalist George Ellery Hale dies. He discovered magnetic fields in sunspots, and was a leader or key figure in the planning or construction of several world-leading telescopes.
2002: Capacitor plague affects several brands of portable envy devices.
Portable envy components at risk of capacitor plague.
