what is the feynman point

The Feynman point is the spot in the decimal expansion of π where the first run of six 9s in a row appears, starting at the 762nd digit after the decimal point.

Quick Scoop: What Is the Feynman Point?

• In π, if you write out the digits after the decimal, at the 762nd place you hit the sequence 999999 — six 9s in a row.

• This string of six identical digits is what people call the Feynman point.

• It’s named after physicist Richard Feynman, who supposedly joked that he wanted to memorize π up to that spot and then say “nine nine nine nine nine nine and so on,” pretending π ended there like a rational number.

• The joke works because π is irrational, so the digits never repeat in a true pattern; this neat run of 9s is just a coincidence, not a sign of hidden order.

Why people find it cool

• Statistically, a run of six identical digits will appear eventually in a “random‑looking” digit string, but the fact it shows up already by the 762nd digit feels surprisingly early to many people.

• Math and science fans like it as a trivia nugget, especially around Pi Day (March 14), where the “Feynman point” often shows up in nerdy posts and videos.

Tiny example to visualize it

If you zoom into π around that region, you’d see something like:

…113499999983…

Here, that 999999 in the middle is the Feynman point.

TL;DR: The Feynman point is the name for the first occurrence of six 9s in a row in π’s decimal expansion, starting at the 762nd decimal place, famously linked to a joking remark by Richard Feynman.
