Pi Day Mashup
It’s Pi Day (and Einstein’s birthday). Celebrate with this mix of tributes to the telltale Greek letter that symbolizes that endless number.
Twenty-five years ago, physicist Larry Shaw, of San Francisco’s Exploratorium, established the first “Pi Day” on March 14th, or 3/14—a fitting date to commemorate an irrational number that so familiarly begins 3.14. The event started as a little staff get-together but ballooned into an international holiday. To get you in the celebratory mood, here are some tributes to those endless digits, and to the Greek letter that symbolizes them.
For a brief history of pi and events surrounding the occasion, visit the Exploratorium’s Pi Day site. (And by the way, March 14th also happens to be Albert Einstein’s birthday.)
This mosaic’s maker had been gathering images of numbers for many months, without this project in mind. When the montage idea struck, “it was just a matter of picking around in my number collections,” he writes on his flickr page. As one flickr user observed, the hole in the keychain in the second tile acts like the decimal in 3.14…
The Fermi National Accelerator Laboratory features a high-voltage transmission line with utility poles built to resemble the Greek letter π. Designed by the lab’s founding director, Robert Wilson, the line provides electricity to the lab’s main substation and a series of powerful particle accelerators.
The architect in this video writes that, “using a formula with pi, I estimated the total dominos in this spiral to be 10,178.75 dominos. I counted the dominos, and the estimate was close. 10,059 dominos were actually used.”

The Tyler Brown Pi Mile is a 3.14-mile running trail on the Georgia Tech campus. There are four starting points on campus, and disc-shaped markers and maps along the way help keep walkers and runners on the trail.

In this flick, “a paranoid mathematician searches for a key number that will unlock the universal patterns found in nature,” according to IMDb.
