A Set deck has 81 cards, each of which displays a design with four attributes: shape, number, shading, and color. Each attribute has three possible values. For example, a card may display one, two, or three identical shapes, and those shapes may be red, green, or purple. A player’s object in a traditional game of Set is to pick out from 12-card

The math was completely correct, the board work was neat and legible, the delivery was professional, and the timing was perfect. But the talk was so dry and formal that the other students quickly reverted to the blank look that suggests they have more interesting things to think about. In contrast, Karen’s presentation on generating functions gained and held the attention of many of the students. She successfully conveyed the beauty and power of generating functions . . . to the front half of the class. The rest couldn’t hear

Shapley. This paper serves as an exemplary model of mathematical exposition, one that every author should strive to emulate. With admirable brevity and dry wit, the six-page article presents a set of novel ideas in a way that is both engaging and informative. It uses examples effectively, and it offers arguments carried out not in mathematical symbols but in ordinary English. It has no references, but it does conclude

How would you present a topic of current mathematical interest to this group in such a way that they, too, can share in the excitement of mathematical discovery? This was the communications challenge that speakers—prominent research mathematicians—faced at the International Mathematical Summer School for Students in July 2011 at Jacobs University in Bremen, Germany. The speakers included John H. Conway, John H. Hbbard, Sergei Tabachnikov, Étienne Ghys, Tadashi Tokieda, Dierk Schleicher, Rostislav Matveev,

A professor of mathematics at Temple University, Paulos is the author of eight books, including Innumeracy: Mathematical Illiteracy and Its Consequences, and numerous, widely read columns, commentaries, and reviews. He is also a lively, provocative presence on Twitter (@JohnAllenPaulos). Paulos will receive his award at the Joint Prize Session at the Joint Mathematics Meetings on January 10, 2013, in San Diego. JPBM established the award in 1988 to reward and encourage communicators who, on a sustained basis, bring mathematical ideas and information to
