My Pi pie for celebrating Pi day! :D This is quite a geek thing, but I really wanted to do it!

Oggi è il giorno del pi greco (http://it.wikipedia.org/wiki/Giorno_del_pi_greco). Negli Stati Uniti si usa festeggiarlo con una torta (per l'assonanza tra Pi, pi greco e pie, torta)... questa è la mia versione!

Alan Lightman by Princeton Public Library

The author of "Einstein's Dreams" -- our first ever "Pi Day Book Pick" -- made an appearance to kick off Pi Day festivities thanks to funding from the NEH. He gave a lecture to a standing room only audience on the topic of Science and the Humanities and what they can learn from each other.
