Pi Day is celebrated on March 14 because its first 3 digits are 3.14 <i>(representing March 14th using month.day notation)</i>. March 14 is also <a href="http://en.wikipedia.org/wiki/Albert_Einstein">Albert Einstein's</a> birthday <i>(he would be 133 years old in 2012)</i>. Pi is an irrational number, meaning that the sequence of its decimal digits continues forever without repeating itself. </p> <p> 3.1415926535897932384626... </p> </center> <h2>Other Pi fun:</h2> <ul> <li><a href="http://www.exploratorium.edu/pi/">Pi Facts & Pi Day Activities at the Exploratorim</a> <li><a href="http://www.joyofpi.com/pilinks.html">Joy of Pi</a></li> <li><a href="http://en.wikipedia.org/wiki/Pi_Day">Pi Day on Wikipedia</a></li> <li><a href="http://pi.ytmnd.com/">Pi.ytmd</a></li> <li><a href="http://two-n.com/pi/" title="An average person can read out approximately 120 digits/min.
