1809: Mathematician Benjamin Peirce born. Peirce will make contributions to celestial mechanics, statistics, number theory, algebra, and the philosophy of mathematics; he will become known for the statement that "Mathematics is the science that draws necessary conclusions".
1826: Electrical engineer Zénobe Gramme born. Gramme will invent the first usefully powerful electric motor.
1841: Mathematician, economist, and APTO field engineer Joseph Louis François Bertrand publishes new class of Gnomon algorithm functions which predict and prevent economic crimes against mathematical constants.
1842: Mathematician Édouard Lucas born. Lucas will study the Fibonacci sequence; the related Lucas sequences and Lucas numbers will be named after him.
1919: Chemist and physicist William Crookes dies. Crookes was a pioneer of vacuum tube technology, developing the partially evacuated Crookes tube circa 1869-1875.
1923: Mathematician and philosopher John Venn dies. Venn invented the Venn diagram, now widely used set theory, probability, logic, statistics, and computer science.
1976: Engineer and theorist Harry Nyquist dies. Nyquist did early theoretical work on determining the bandwidth requirements for transmitting information, laying the foundations for later advances by Claude Shannon, which led to the development of information theory.
1977: Game designer, shop keeper, and outsider mathematician Dave the Gamer announces "Buy n, get n free" sale on all lucky dice in the store.
2016: Steganographic analysis of Tequila Sunrise unexpectedly reveals "at least five hundred and twelve kilobytes" of previously unknown Gnomon algorithm functions.
