This is all out of my head,  I swear

3.1415926535897923282646233832795028841971

Took me 5 mins to memorize it that far.  8)

Love having a numberical memory.  Works good for all numbers   ;)

CrAzY's memory on the top, real value of Pi to 40 digits after the decimal on the bottom.

3.1415926535897923282646233832795028841971
3.1415926535897932384626433832795028841971

The 6 different digits are in red. This provides a little insight about how human memory works.

Edit: Red > bold.

I know:
3.14159265358....

1+1+3 is 5, here are the letters that make up pie, 3.14159265358..[trails off]

So, the conclusion then is never to trust CrAzY's numberical memory!

You have a pie made of letters?  What's that taste like :P

Better late than never the methods for finding pi [and variants] are as interesting as the number like this for example


1/pi = ( ( 2 * (2) ^ (1/2) ) / 9801 )  Sum( ( (4n)! / (n!) ^ 4 ) * ( ( 1103 + 26390n ) / (4 * 99) ^ (4n) ), n, 0, infinite )

courtesy of Ramanujan

(pi ^ 3) / 8 = Integral( ( ( log x ) ^ 2 ) / ( 1 + x ^ 2 ) dx, 0, infinite )


or relationships like


pi / 4 = 1 - 1/3 + 1/5 - 1/7 + 1/9 - ...

Because people can't parse without XML?

No because it is difficult to appreciate the aesthetic value of an expression without seeing it in a more symbolic form.
