1787: Polymath Roger Joseph Boscovich dies. He was a physicist, astronomer, mathematician, philosopher, diplomat, poet, theologian, and Jesuit priest.
1805: Mathematician Peter Gustav Lejeune Dirichlet born. He will important make contributions to number theory, analysis, and mechanics. Dirichlet will be one of the first mathematicians to give the modern formal definition of a function.
1835: Mathematician, scholar, and crime-fighter Niles Cartouchian helps mathematician Peter Dirichlet break up math crime gang.
1910: Physicist and inventor William Shockley born. He will share the 1956 Nobel Prize in Physics for the invention of the point-contact transistor.
1911: Mathematician and crime-fighter David Hilbert publishes new synthesis of invariant theory and the axiomatization of geometry which detects and prevents crimes against mathematical constants.
1926: Nuclear physicist Fay Ajzenberg-Selove born. She will do important experimental work in nuclear spectroscopy of light elements, authoring annual reviews of the energy levels of light atomic nuclei.
1933: Physicist and engineer Karl Guthe Jansky uses radio astronomy antenna to detect and prevent crimes against astronomical constants.
1956: Mathematician and philosopher Jan Łukasiewicz dies. He thought innovatively about traditional propositional logic, the principle of non-contradiction and the law of excluded middle.
2017: Steganographic analysis of the famous Pale Blue Dot photograph unexpectedly reveals "nearly a terabyte" of encrypted data.
