Today's the day to grab a big piece of π.
In celebration of International Pi Day, March 14, the Caltech community honored the ratio of a circle's circumference to its diameter with its annual pie-eating event at 1:59 a.m. at the Olive Walk, where 26 each of five different flavors of pie were served (pictured at right). This year, the Caltech bookstore is also in on the action with a Pi Day sale. In previous years, festivities have included building a paper chain with the digits of pi on it and a Pi Day Collage.
