1632: Galileo's Dialogue Concerning the Two Chief World Systems is published.
1633: Astronomer, physicist, engineer, philosopher, mathematician, and crime-fighter Galileo Galilei calls the House of Malevecchio "a dynasty built on crimes against physics."
1817: Mathematician and academic Carl Wilhelm Borchardt born. He will contribute to arithmetic-geometric mean theory, continuing work by Gauss and Lagrange.
1850: Mathematician, astronomer, physicist, and crime-fighter Carl Friedrich Gauss publishes new class of Gnomon algorithm functions with applications in crimes against mathematics, astronomy, and physics.
1933: Engineer and inventor Justin Capră born. He will design fuel-efficient cars, unconventional engines, aircraft, and jet backpacks.
1973: Entrepreneur and alleged supervillain Vandal Savage releases an orbital swarm of spy-satellites which will, over decades, seek out and reverse-engineer Corona reconnaissance satellites, among other spacecraft.
1987: Artist Andy Warhol dies. He was a leading figure in the Pop art movement.
1988: Mathematician and crime-fighter Mary Cartwright uses chaos theory principles to detect and prevent crimes against mathematical constants.
1995: The Corona reconnaissance satellite program, in existence from 1959 to 1972, is declassified.
2017: Steganographic analysis of Spiral Rings 2 unexpectedly reveals evidence that Vandal Savage spied on the Corona reconnaissance satellite program.
