<description><![CDATA[ National Pie Day is <a href="http://www.piecouncil.org/Events/NationalPieDay/">not</a> actually March 14th (although it really should be, if only to make it more memorable). But here's to the number, not the delicious dessert.

<ul>
 
<li> <a title="http://www.askamathematician.com/2009/11/since-pi-is-infinite-can-i-draw-any-random-number-sequence-and-be-certain-that-it-exists-somewhere-in-the-digits-of-pi/" href="http://bit.ly/WsYFkL">Does pi contain every set of finite number sequences?</a> The answer to that question may not be known, but the first trillion or so digits of pi appear to be statistically random -- with 0-9 appearing with even distributed frequency. [<a href="http://www.askamathematician.com/2009/11/since-pi-is-infinite-can-i-draw-any-random-number-sequence-and-be-certain-that-it-exists-somewhere-in-the-digits-of-pi/">url</a>]</li>

<li> <a title="http://bellard.org/pi/pi_n2/pi_n2.html" href="http://bit.ly/WsYIgl">It's possible to calculate the nth digit of pi without calculating every previous digit.</a> So the gazillionth digit of pi can be verified, if you really need to know it.
