Shannon’s 1938 master’s thesis mapped George Boole’s algebraic scheme for doing yes-no, either-or computation onto current switching devices such that circuit closed was “true” and circuit open was “fal

ogic by Wilfrid Hodges. Logic for Computers Western civilization mostly survived on syllogisms and stoic logic for nearly two thousand years before George Boole devised his theory of binary logic in 1847. Boole developed an elegant mathematical system for representing logical statements that allowed simple ar

t knowledge from his parents, from the streets around him, his new friends, anywhere. In a library in Calcutta, for instance, he once found a copy of George Boole’s 1854 book “An Investigation Into the Laws of Thought”. Boole invented symbolic logic on those pages and though his instincts were grounded in an age
