Topic: Ramanujuan-like formula

John Baez (Oct 10 2020 at 20:06):

I blogged about a formula for $1/\pi^2$ that lets you compute the nth decimal digit of $1/\pi^2$ without computing all the previous ones:

• Decimal digits of $1/\pi^2$.

No formula of this sort is known that lets you compute individual decimal digits of π

Seems like good evidence that decimal is a flawed base. :smile:

True. Somewhere in the universe there's a civilization where people have just two fingers on each hand - and they're way ahead of us.

Unless the people in that civilization have five hands... in which case they're right back in the same boat we're in with decimal base. :upside_down:
