So, my friend Steve just found me on Facebook. That's cool, Steve's an interesting guy and it never occurred to me to look for him. Anyway, I quickly scanned his recent comments and he pointed out that some folks write July 22 as 22/7 ... which is a famous historical approximation of pi (handed down to us from Archimedes). So, today is Pi Approximation Day... which I find to be at least as interesting as Pi Day itself (March 14).

According to my windows calculator program: 22/7 = 3.1428571428571428571428571428571 According to my memory: pi = 3.1412565359

So, that's accurate in the first two digits, with an error factor of roughly 0.04% Pretty cool
