This amazing YouTube video features perhaps the smartest man in the world. His IQ is off the charts. He may be smarter than Einstein, Galileo and Newton. But he doesn’t exactly fit in with the world’s greatest thinkers.

His name is Christopher Langan. He taught himself to read at 3. He breezed through school. But he never finished college. (He was smarter than the professors.) You might expect to hear about a life of high-profile research. But Langan is nothing like you’d expect.

Langan lives a double life. He’s been a bouncer, construction worker, cowboy, firefighter and farmhand. But at home, he works on his Cognitive-Theoretic Model of the Universe. He’s exploring the connection between the mind and reality. He believes the theory could literally explain everything.
