The Feynman point comprises the 762nd through 767th decimal places of π, consisting of the digit9 repeated six times. Since π is an irrational number with an infinite non-repeating decimal expansion which may well be normal, any given sequence of any length can be expected to be found given enough digits, but it is the appearance of the sequence after relatively few digits which makes the Feynman Point a mathematical curiosity. The name refers to a remark made by the physicistRichard Feynman, expressing a wish to memorise the digits of π as far as that point so that when reciting them, he would be able to end with "... nine, nine, nine, nine, nine, nine, and so on."

Feynman Point (http://mathworld.wolfram.com/FeynmanPoint.html) from MathWorld
Feynman was born in Far Rockaway, Queens, New York; his parents were Jewish and attended synagogue every Friday, although they were unritualistic in their practice of Judaism as a religion.
Feynman gained great pleasure from coming up with such a "freshman level" explanation of the connection between spin and statistics (that groups of particles with spin 1/2 "repel", whereas groups with integer spin "clump"), a question he pondered in his own lectures and which he solved in the 1986 Dirac memorial lecture.
Feynman did not dispute the quark model; for example, when the 5th quark was discovered, Feynman immediately pointed out to his students that the discovery implied the existence of a 6th quark, which was duly discovered in the decade after his death.
