Thursday is Pi Day! March 14, or 3/14, is the day we celebrate the mathematical number Pi, which represents the ratio of a circle's circumference to its diameter.

Emma Haruka Iwao (@Yuryu) has broken the previous world record and has calculated Pi to 31,415,926,535,897 digits (over 31 trillion). She joins Here & Now's Lisa Mullins from Tokyo to discuss her feat.
