Sports off er a multitude of instances involving data, strategies and chance, each of which is perfectly suited to mathematical analysis. Beyond the obvious uses of mathematics for things such as rating baseball players and football quarterbacks, mathematics is used to design the dimple patterns on golf balls and the com- position of racing tires; it is used for scheduling tournaments and for ranking teams; and it is used to determine tactics and to predict the ultimate limits in sports records. In the 1960s the ABC television network began a popular weekly series called “Th e Wide World of Sports” that spanned the globe to show the tremendous variety of sports. For 2010, the Joint Policy Board for Mathematics has chosen the theme “Mathemat- Th e 2010 Mathematics Awareness website has articles on ics and Sports” to highlight the intersection of the sports world baseball, basketball, football, golf, soccer, track and fi eld, tennis, with the wide world of mathematics — a universal language that and car racing as well as videos and links to other resources, at is used to investigate problems ranging from the athletic to the . cosmic.

Th e rich program 6ranged from plenary lectures aimed at a broad mathematical public to small and specialized sessions on mathematical and educational research, from a poster session in which undergraduates presented their research to the AMS’s “Current Events” session in which leading mathematicians talked about the most important developments of 2009. Social activities ranged from the usual banquets to a knitting circle and a tweet-up. Th ere were bloggers and a Flickr page with photos. Th is issue of MAA FOCUS includes our usual selection of photos. For even more photos, visit O[[W!^^^ÅPJRYJVT and search for the MAA. Online, the photos are grouped into thematic sets, while our spread, on pages 5–7, is the usual kaleidoscope of images. Th e Joint Meetings are the venue for awarding several mathematical prizes; on pages 8–11 you will see photos of (almost) all the winners. Also in this issue you will fi nd Martha Siegel’s fi nal report as MAA Secretary and an article on Martha’s work for the Association over these last many years; a report, with photographs, on the Mathematical Art exhibit; personal accounts from an undergraduate participant and from an about-to-graduate PhD student hunting for jobs; a report on the special session on mathematics in business, industry, and government; and some interesting news from the new SIGMAA on Math Circles. 144 :OVY[ ;HRLZ )` -LYUHUKV 8 .V\]vH Demaine is Pólya Lecturer advantage of the two-day schedule, they asked four speak- ers to give extended lectures on important mathematical Erik Demaine was chosen by the MAA Board of Governors as the books: Alexander Jones on Ptolemy’s Almagest, George 2010-2012 Pólya Lecturer.
