Albert Einstein first visited Princeton University in 1921, the year before he won the Nobel Prize in physics. He came to deliver lectures on the theory of relativity and to accept an honorary degree, and he ended up living in Princeton for the rest of his life while working at the Institute for Advanced Study. He’s a significant part of Princeton’s history, which is why he’s celebrated every year in town on his birthday, March 14th or 3.14, the mathematical constant known as Pi. Since Einstein was quite the mathematical wizard, why not celebrate both his birthday and Pi? Join us in Princeton this March 9th and 14th for some Pi-rades, pie eating, pie judging, pie throwing, Pi reciting, pizza pie judging and Einstein look-alike games for a Pi-ful day of celebrations. You might just leave with a new appreciation for math.
