2 ноября 1815 года родился создатель математической логики Джордж Буль

"Physicists,” meaning people that specialize in natural sciences, recognize the son of a rather poor artisan as a famous mathematician, creator of mathematical logic. “Physicists" understand the terms Boolean algebra and Boolean logic, but often are unaware of the things that “poets" know. For “poets,” professor of mathematics at Queen's College, Cork, and husband of the teacher Mary Everest is first of all the father of five daughters, four of whom either pursued science or were the wife or mother of a mathematician. And his fifth daughter is familiar to all Soviet lovers of reading. Her name was Ethel Lillian, her married name was Voynich. Yes, the very same Voynich that authored the cult novel The Gadfly.
