ilization 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 arithmetical operations to answer logical questions.

scheme for doing yes-no, either-or computation onto current switching devices such that circuit closed was “true” and circuit open was “false.” Using Boole’s laws such as “Not(A and B)” always equals “(Not A) or (Not B)” led to schemes for circuit routing through electronic gates which also serve for inf

ends, 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 of steam and machines, his vision still echoes in 132 HOUSE
