What Is the Feynman Point?

The Feynman point is a sequence of six nines commencing at the 762nd place of the decimal representation of pi. The Feynman point is named after the theoretical physicist Richard Feynman.

Feynman mentioned in a lecture that he wanted to memorize the pi sequence until the 762nd place so that he could finish his recitation with "nine, nine, nine, nine, nine, nine and so on." The next sequence of six consecutive digits in pi is found at the 193,034th position, and it is also a sequence of six consecutive nines. The probability of there being any six digit sequences in pi is nearly 0.08 percent and the probability of a sequence of six nines is 0.0686 percent.
