How high can you Pi?

Most people can remember the 3.1415 part. It takes a real enthusiast to get into the famous constant's double digits. Simply put, pi is the ratio of a circle's circumference to its diameter. Less simply, it is a number found in countless mathematical equations, from eighth grade geometry to Fourier transforms. It's a literal constant in many areas of NSF-funded mathematics, science and engineering. That the digits of pi go on forever without repeating also appeals to many people more philosophically, as a challenge to know as much as we can about a seemingly infinite number. Or, perhaps just as a means by which to test our memorization skills. For the Pi Day of the century, March 14, 2015, we asked NSF staff to recite as many digits as they could of the irrational number. Think you can beat our top pi fan? This year is a special year for pi as not only can we celebrate it on March 14th aka 3.14, we have the unique opportunity to recall the following digits beyond those most remembered to find the exact perfect moment for celebration: 3.14.15 at 9:26:53. (3.141592653…) You get the picture. Happy Pi Day!
