For engineers around the world, March 14 has become synonymous with Pi Day. Celebrate the Columbia Pi Day Challenge with a π day gift! Join us for happy hour on Friday, March 15, for some Pi Day fun with the Columbia Alumni Board of Norcal, get free Pi Day give-aways, play Pi Day games with your fellow alumni and friends, and suppport your alma mater with a Pi Day gift.  Last year, February 14 through March 14 marked the inaugural year for Columbia Engineering Pi Day #PiSEAS, a successful month-long online fundraising event that celebrated the ways that Pi brings Columbia Engineers together. This year your support is key in helping to drive another great Columbia Engineering Pi Day! All the ticket sales from this event will go to SEAS to support Columbia engineers. Also visit engineering.columbia.edu/piday to donate in a factor of Pi.
