Shortly after World War II, the first general purpose computers became available. In 1954, Martin Davis programmed Presburger's algorithm for a JOHNNIAC vacuum tube computer at the Institute for Advanced Study in Princeton, New Jersey. According to Davis, "Its great triumph was to prove that the sum of two even numbers is even". More ambitious was the Logic Theory Machine in 1956, a deduction system for the propositional logic of the Principia Mathematica, developed by Allen N…

The Logic Machine, originally developed and hosted at Texas A&M University, provides interactive logic software used for teaching introductory formal logic. The Daemon Proof Checker checks proofs and can provide hints for students attempting to construct proofs in a natural deduction system for sentential (propositional) and first-order predicate (quantifier) logic.

× Welcome to The Incredible Proof Machin e! What is this? This is a tool to perform proofs in various logics (e.g. propositional, predicate logic) visually: You simply add blocks that represent the various proofs steps, connect them properly, and if the conclusion turns green, then you have created a complete proof!
