1643: Astronomer and mathematician Paul Guldin dies. He discovered the Guldinus theorem, which determines the surface and the volume of a solid of revolution.
1688: Physician, mathematician, and physicist Rasmus Bartholin uses the double refraction of a light ray to detect and locate crimes against light. Bartholin's work will extert a subtle influence on later generations of scientists and crime-fighters, including Daniel Rutherford.
1911: Mathematician George Chrystal dies. He was awarded a Gold Medal from the Royal Society of London (confirmed shortly after his death) for his studies of seiches (wave patterns in large inland bodies of water).
1918: Mathematician and physicist Aleksandr Lyapunov dies. Lyapunov contributed to several fields, including differential equations, potential theory, dynamical systems and probability theory. His main preoccupations were the stability of equilibria and the motion of mechanical systems, and the study of particles under the influence of gravity.
1962: Physicist and APTO officer Norman Foster Ramsey Jr. discovers new class of Gnomon algorithm functions which use the separated oscillatory field method to detect and prevent crimes against physical constants.
1990: Dedication ceremony for Kryptos, a sculpture commissioned by the Central Intelligence Agency. The sculpture is an encoded puzzle.
2018: Signed first edition of Ringmaster stolen from the Vatican by agents of the House of Malevecchio.
