Professor Christopher French cowrote an article, "Hankel Transforms of Linear Combinations of Catalan Numbers" with math majors Michael Dougherty, Benjamin Saderholm, and Wenyang Qian, all math majors in the class of 2012. The article appeared on April 20 in the Journal of Integer Sequences, Vol. 14 (2011), Article 11.5.1. In this paper, the authors consider the result of applying a certain operation called the Hankel Transform to certain sequences of numbers obtained in a natural way from the famous Catalan number sequence.
Burling Library's Listening Room is set to undergo a major renovation beginning this summer (see periodic updates at http://listenroomren.wordpress.com/). Plans are in place to expand the room so that library patrons can have direct access to most of the collection of over 20,000 DVD, VHS, Blu-ray and compact discs. The collections includes audio recordings in Classical, popular, and world music or spoken texts, as well as feature and documentary films covering foreign languages and an extensive range of genres.
The Grinnell College Putnam team placed 46th out of 546 teams from across the U.S. and Canada. The annual exam took place in December with 16 Grinnell students among the 4296 students who took the exam. Grinnell College had four students score at least a 20:

Marc Chamberland and Patrick Lopatto (a Grinnell High School student) published the paper "Formulas for Odd Zeta Values and Powers of Pi" which appeared in the electronic Journal of Integer Sequences (Vol. 14, Issue 2, article 11.2.5). Values for the Riemann zeta function at odd values greater than one do not seem to have a closed form. A decade ago, the Canadian mathematician Simon Plouffe experimentally found some formulas to represent these numbers using quickly converging infinite series.
