Contemplation by a team of mathematics teachers of the four-dimensional structure of the game Set has given rise to some intriguing mathematical research worthy of publication in a mathematics journal—and a novel variant of the fast-paced pattern-recognition game. 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 May 2013 issue of the American Mathematical Monthly includes a timely reprint of the influential 1962 article “College Admissions and the Stability of Marriage” by David Gale and Lloyd S. 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

Your audience consists of about 100 talented mathematics students, gathered from around the world. Some are high school juniors and seniors; others are college freshmen and sophomores. 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,

John Allen Paulos is the recipient of the 2013 Joint Policy Board for Mathematics (JPBM) Communications Award. 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
