901: Physician, astronomer, and mathematician Thābit ibn Qurra dies. He made important discoveries in algebra, geometry, and astronomy; in astronomy, Thabit was one of the first reformers of the Ptolemaic system.
1583: Cryptographer and diplomat Blaise de Vigenère (nonfiction) uses Gnomon algorithm techniques to invent a cipher which is resistant to mathematical crimes.
1809: Physicist and academic Antoine César Becquerel uses electricity to power new type of scrying engine.
1851: Mathematician and academic Carl Gustav Jacob Jacobi dies. He made fundamental contributions to elliptic functions, dynamics, differential equations, and number theory.
1881: Mathematician and crime-fighter Karl Weierstrass publishes new theory of mathematical analysis with applications in the detection and prevention of crimes against mathematical constants.
1899: Mathematician and academic Marius Sophus Lie dies. He largely created the theory of continuous symmetry and applied it to the study of geometry and differential equations.
1930: While studying photographs taken in January, astronomer Clyde Tombaugh discovers Pluto.
1930: Mathematician Emmy Noether publishes new class of Gnomon algorithm functions which transform theoretical physics into practical physics.
1967: American physicist and academic J. Robert Oppenheimer dies. His achievements in physics included the Born–Oppenheimer approximation for molecular wavefunctions, work on the theory of electrons and positrons, the Oppenheimer–Phillips process in nuclear fusion, and the first prediction of quantum tunneling.
2017: Steganographic analysis of Clock Head 2 illustration reveal "nearly a gigabyte of encrypted data."
