An international "geek" holiday all got started at San Francisco's Exploratorium 20 years ago today – creator Larry Shaw, physicist, tells how

From San Francisco to New York, in museums, universities, classrooms and in the privacy of one's own home, (and of course on Second Life), people are celebrating Pi. It's the 20th anniversary of the celebration of Pi Day, an international holiday born at San Francisco's Exploratorium. In an era when math and mathematicians have become sexy again, it's worth recounting how Pi Day came to be and why it is that people go to the Exploratorium and gather around the Pi Shrine to perform pi-related rites and eat ritual food -- be it apple pie or pizza pie -- in honor of this special number. Pi Day celebrations culminate, appropriately enough, on March 14 at 1:59pm. That's the third month, the fourteenth day, at 1:59pm, corresponding to the first 6-digits of Pi.

And as an added bonus, 3/14 is also Einstein's birthday.
