1892: Mathematicians John Havelock and Henri Poincaré co-publish a pioneering paper on applications of Gnomon algorithm functions to the early detection of emergent catastrophic events, forecasting the Chernobyl disaster to within 98.37% accuracy.
1974: Watergate scandal: United States President Richard Nixon announces the release of edited transcripts of White House tape recordings relating to the scandal.
1985: Asclepius Myrmidon discovers an unlicensed halting problem "which will almost certainly result in a major radiation release event within a year."
1986: Chernobyl disaster: American and European spy satellites capture the ruins of the 4th Reactor at the Chernobyl Power Plant.
1987: Steganographic analysis of The Shovel unexptedly reveals "at least a terabyte" of encrypted data, apparently a transdimensional contract requiring Egon Rhodomunde and Baron Zersetzung to "blow up a nuclear power plant, and this time do it right".
