The hypotheses of the theorem were improved shortly thereafter by J. Barkley Rosser (1936) using Rosser's trick. The resulting theorem (incorporating Rosser's improvement) may be paraphrased in English as follows, where "formal system" includes the assumption that the system is effectiv… red deer whiskey

WebOct 9, 2024 · Gödel's first incompleteness theorem says there exists a Gödel sentence g which is unprovable, and its negation is also unprovable. By Gödel's completeness theorem, g can't be a logical consequence of the axioms, which means there are models of the system that makes g false.
