Pi Day tomorrow!

3/14 or March 14 is Pi Day! (In Europe, 22 July, or 22/7, is Pi Approximation Day.)

How many digits of Pi have you memorized?

I have memorized 11 digits of pi in Base-Ten: 3.1415926535. I believe that's enough precision to estimate the circumference of a sphere the size of Earth (give or take a few molecules).

But do you know the series that generates pi?

It's the Taylor Series of one of the inverse trigonometric functions (at least I think it is.) Plug in 1.
