Mathematics parties for 'Pi Day of the century'

03-13-2015


Like little kids before Christmas, the Purdue Department of Mathematics couldn’t wait to celebrate the Pi Day of the century.

March 14, 2015, has been dubbed such because the month, day and year match the approximation of pi – 3.1415. Add 9:26:53 a.m./p.m. to the mix and you have the ultimate pi time, as the next digits are 92653.

So, for math fiends, 9:26 and 53 seconds a.m. or p.m. is the ultimate time of the century.

And what better way to celebrate this unique time of year than with pie?

On March 12, the Mathematics department brought in about 20 fruit, pumpkin and pecan pies to the Mathematics Library to help get the celebration started and to help welcome the visiting Dr. Francis Su, president of Mathematical Association of America and Benediktsson-Karwa Professor of Mathematics at Harvey Mudd College.

Su met with graduate students before the pie proceedings. Afterward, he gave a colloquium talk on “Combinatorial Fixed Point Theorems” in Lawson Computer Science Building. Su then completed his Purdue stay by hanging out with the Math Club in Recitation Hall. Su talked with undergraduates and graduate students after giving another presentation. He mixed in his experience of using his mathematical prowess in the social sciences in his lecture "Voting in Agreeable Societies.”
