Pi

 
 
3 . 1 4 1 5 9 2 6 5 3 5 8 9 7 9 3 2 3 8 4 6 2 6 4 3 3 8 3 2 7 9 . . .
 
Last month, we went to St Louis for a weekend getaway (unfortunately, the Cards were on a road trip). This picture is in front of one of St Louis' top rated pizza places.  Appropriately called Pi, with of course the symbol on the door, and the digits running all around the building.
 
The server told us a story about a little boy that started looking at the digits, and told the restaurant owner "you're missing a number".  The owner didn't believe him, but did look it up, and sure enough, the artist applying the numbers to the walls did miss a number.  That little boy could have been me many decades ago!

\pi = \frac{C}{d}

Ever since I was a young child, I have been fascinated with Pi.  I think because it is as close to infinity as our finite minds can grasp. Infinity; there is no start, there is no end, it always was, it always is, it always will be.

This is a great website for learning even more about Pi.

I memorized the first 30 digits of Pi some time ago, and can quote them by rote just like I typed them above.  If you want to really be challenged though, go to this website. It lists the first million digits of Pi.  As late as 2011, Pi digits have now been mathematically calculated (by a super computer) to go out as far as 10 trillion digits. We all know that infinity goes farther than that, (as does Pi), but think about it. 10 trillion known digits. Amazing.

What is Pi? 


Enjoy your Pi :-)
