Meaning of Feynman point | Babel Free

Definitions

The position (at the 762nd digit after the decimal point) in the decimal expansion of pi at which a sequence of six consecutive nines first appears, unexpectedly early in view of the expected and otherwise apparent randomness of said expansion.

Examples

“What is the Feynman Point⟳? The Feynman Point⟳ was named after Nobel Prize-winning physicist Richard Feynman (1918–1988), who once joked he wanted to memorize pi up to "999999 ... and so on and so on," as if to say⟳ pi continues from the Feynman Point⟳ with nines forever. This is not true, of course, and the sequence of nines is a mere coincidence—thus, the joke of the Feynman Point⟳.”
