This sentence is false ...

This sentence is false, a paradox of monumental proportions, acted as the start point for  Gödel to prove that there is no complete mathematical system indirectly connects to  Turing's forays into computation and AI, thus forever changing how man views reality. As an aside, the two never met. 

Excellent to a fault. :)

This story of greatness and weakness, of genius and hallucination, is based on the parallel lives of Kurt Gödel, the greatest logician of many centuries, and Alan Turing, the extraordinary code breaker during World War II. Taken together their work proved that truth is elusive, that knowledge has limits, that machines could think. Yet Gödel believed in transmigration of the soul and Turing concluded that we were soulless biological machines. And their suicides were complementary: Gödel, delusional and paranoid, starved himself to death fearing his food was poisoned. Turing ate a poison apple, driven to suicide after being arrested and convicted of homosexual activities. These two men were devoted to truth of the highest abstract nature, yet were unable to grasp the mundane truths of their own lives. Through it all, the narrator wonders, along with these two odd heroes, if any of us can ever really grasp the truth.

The limits of knowledge applies.
