Title:  Generalizing a Binomial Coefficient Identity of Beckwith

Abstract:  In 2006, David Beckwith submitted a specific binomial 
coefficient identity to the Problems Section of the American 
Mathematical Monthly (problem #11220).  Later that year, I had the 
privilege of proving the result combinatorially with Art Benjamin, Jenny 
Quinn, and Mark Shattuck.  Along the way, our combinatorial proof 
allowed us to generalize Beckwith's identity in multiple directions.  In 
this talk, I will share numerous proofs of Beckwith's identity along 
with some of our generalizations.

The talk will be geared towards a general audience.  Bring a calculator 
and some scratch paper so we can complete some calculations together!!!
