... The Feynman point is a sequence of six 9s that
begins at the 762nd decimal
place of the decimal representation of π. It is named after physicist Richard Feynman , who once stated during a lecture he
would like to memorize the
digits of π until that point, so
he could recite them and quip
"nine nine nine nine nine nine
and so on", suggesting, in a tongue-in-cheek manner, that π is rational.
