Professor Jan Minton Professor Jan Minton is co-coordinator of the Roanoke Valley Reef.
This project combined beautiful crochet work from over 200 contributors with the mathematics of hyperbolic geometry and the ecology of coral reefs. The exhibit was on display in Olin Gallery through the first week of March and attracted thousands of visitors. Biology's Darwin Days, Chemistry's Fisher lecture and various biology and creative writing classes all connected to the Reef to create a college-wide series of events that also involved the community.

Dr. Rama Balasubramanian Physics professors Dr. Matt Fleenor and Dr. Rama Balasubramanian are enjoying their sabbaticals . Dr. Bala has continued her nanotube research and spoke on "Investigations on the role of nanocatalysts in the formation of nanotubes" in Austin, Texas. She also attended a meeting on STEM education in Kansas City. Dr. Fleenor spoke at the NRAO Astronomy meeting on "How multiwavelength datasets aid in galaxy evolution studies" and co-authored a published  article. MCSP will be glad to welcome back Drs. Bala and Fleenor after productive semesters.

Dr. Roland MintonDr. Roland Minton's popular press book Golf By the Numbers was published by Johns Hopkins University Press.
Dr. Minton tries to bring Moneyball to golf with this analysis of golf statistics and various applications of mathematics to golf. The PGA Tour collects data on every shot taken, with distances measured to the inch. Dr. Minton used this data to develop rating systems for golfers for overall performance and individual categories such as putting and driving. Other topics include the role of luck in putting, and course strategies.

The annual student celebration of Pi Day (3/14) was a smashing successThe day opened with media coverage from the local NBC affiliate. Teams of students then participated in a "Pi-athlon" of mathematical events, such as solving a Sudoku with only 18 clues (given, of course, by the first 18 digits of pi). The cafeteria served chicken pot pie for lunch. Then came the pie-ing of professors, students, and our man Chaplain Henrickson, who brought a special clean-up crew! Proceeds of the pie-ing go to charity. The day's penultimate event was an entertaining talk by Dr. Taylor on "Magic, Mathemagic, and Mathematics."
