I used to do pi runs back when I used to overclock computers. This is an awesome achievement.

My favorite comment:
According to wikipedia:

...a physicist needs only 39 digits of Pi to make a circle the size of the observable universe accurate to one atom of hydrogen,
I'm wrapping my head around that calculation... pi (to 39 digits) * radius of known universe ^ 2 and you have enough precision (assuming you retain 39 decimal places?) to distinguish between two different atoms.

I think they mean :

(0.1^39) < size of an atom

By circle, You can presume they mean the accuracy of the radius.

If you include R^2, you're implying that the difference in area of two circles (one scaled by 1+(0.1^39)), is less than the area occupied by an atom
