Childers Victorious in Atlanta

by Roland Minton on January 12, 2017

Roanoke College had a strong presence at the Joint Mathematics Meetings in Atlanta, with Adam Childers winning an award, four faculty and one student presenting talks, and two other faculty attending. The national meeting, held January 4-7, 2017, is the largest gathering of mathematicians in a year, with over 6000 attendees.

David Moreau, a sophomore physics major, presented “A Student Stat Crew at Roanoke College.” Faculty talks included Dave Taylor and Hannah Robbins on “Curing the High DFW Rate in First Year Calculus”; Adam Childers on “Thinking Outside the Box-Score in Lacrosse”; and Roland Minton on “Skill and Randomness on the PGA Tour.” Maggie Rahmoeller organized a session on diversity for Project NeXt, which is a network for young faculty.

Adam Childers received an award for his talk at the 2016 meeting in Seattle. His presentation “Facebook Consulting: A Semester-Long Project for Introductory Statistics” was voted the Outstanding Contributed Paper in Statistics Education in 2016. Congratulations, Adam!

The RC math group returns from the meeting with several new ideas for teaching and research, and an enhanced reputation for quality pedagogical and research presentations. We enjoyed great food in Atlanta, an unexpected winter storm, and some great conversations.


Math Lessons and Carols

by Roland Minton on November 28, 2016


One of the best ways to start the Christmas season is with Lessons and Carols of Christmas, presented by the Roanoke College Choir and Oriana Singers at St. Andrew’s Catholic Church. The soaring vocals and warm harmonies bring meaning back to a season cheapened by October decorations and Black Friday madness. Director Jeffrey Sandborg’s choirs are outstanding, and St. Andrew’s is a fantastic setting.

You may be wondering how math gets into this. The connection between math and music is actually very strong. For example, the intricate weaving of parts in Benjamin Britten’s This Little Babe is highly mathematical. Higher level mathematics explores the magical ways that simple rules and interactions can produce complex and beautiful patterns. Steven Strogatz’s TED talk gives several great examples of this. The MCSP conversation series event on Thursday, December 1, also explores the relationship between math and music.

At this year’s Lessons and Carols, mathematics played a more direct role as Roanoke College math professor Maggie Rahmoeller accompanied Oriana on her oboe in a gorgeous version of There Is No Rose. Collaborations such as this are part of what make Roanoke College great.

Stat Crew Leads to Jobs

by Roland Minton on October 28, 2016


“How did you get your job offer from ESPN?” was one of the questions at last night’s MCSP Conversation Series talk. Taylor Ferebee, Sky Weber, Abby Hobby, and Connor Sampson talked about their summer work in sports analytics, the hot new field of statistical analysis of sports. Work with the Stat Crew has led to internships with professional sports teams and a Summer Scholars project. In Taylor’s case, it has also led to the possibility of doing analytics for ESPN.

Stat Crew is a group of students collecting and analyzing data for Roanoke College athletics teams. It is an excellent collaboration between academics and athletics, giving the coaches and players useful information and giving the students experience in sports analytics. A presentation on Stat Crew at a regional meeting last April included the Crew’s work on lacrosse. This caught the eye of the director of analytics for the Atlanta Blaze of Major League Lacrosse. A couple of conversations and emails later and Taylor and Connor had internships with the Blaze.

Taylor and Connor had separate projects, both involving watching game film and creating charts and visualization of passing and shooting tendencies of teams in the league. Connor focused on shot charts, creating profiles of locations on the field from which shots were taken and locations in the goal for successful shots. Taylor focused on passing schemes, where successful passes started and ended and which passes led to good scoring opportunities. The combination of their work gave the Blaze coaches detailed scouting of their players and each of the other teams and players in the league. Taylor created different types of graphs to find the formats that best conveyed information to the coaches.

Sky interned with the Cape Cod Baseball League. She computed various baseball metrics for the league. Park factors measure the influence of the different parks (which have different sizes and shapes and looks) on the outcomes of the games. Smaller parks, for example, create more home runs. Sky can tell exactly how many more or less for each park, and how to adjust each player’s record to allow fair comparisons. She also computed WRC+, which quantifies the total offensive contribution of a given player, adjusted to remove home park biases. Her statistics are used by professional scouts to evaluate players.

Abby created a successful Summer Scholars project. She is captain of the women’s soccer team, and her project is a statistical comparison of strategies and results in women’s versus men’s professional soccer teams. She found several differences, including higher scoring rates off of corner kicks in the women’s game. Abby adapted a computer app used by Stat Crew for lacrosse to allow her to collect detailed passing data for soccer. Her data allows her to measure the quality of a shot, given distance and angle to the goal and location of defenders. This will allow Stat Crew to better evaluate shots in future seasons.

One of the themes that emerged in the four talks was the need to program. Connor emphasized that the programming did not have to be very sophisticated, but when dealing with large amounts of data you do not want to work by hand. Another theme was the importance of gaining experience in the field, an opportunity that Stat Crew provides. Part of the answer to getting a job at ESPN is being able to dazzle recruiters with your experience, something Taylor did on her website with many of the visualizations that she created for the Blaze, Stat Crew, and her own research.

Sports analytics is an exciting new field. Join Stat Crew (contact Dr. Minton at and get started!

All Square with Math and Art

May 6, 2016

One of the definitions of square is “conventional” or “boring.” This spring’s art gallery presentation by Jan Minton’s Honors 301 class puts the lie to that. The phrase “mind blown” was used in at least one student’s description of her work. Students in the Mathematics and Art class created visual representations of how you can […]

Physics majors participate in Edgar Allen Poe theatre production

April 21, 2016

The members of the Physics Group often advertise that “physics goes with anything.”  More formally, we maintain that there is no academic endeavor where the creative problem-solving approaches introduced in physics are detrimental.  In ten years of physics majors at Roanoke, we can list the following double majors: biochemistry, chemistry, computer science, math, music, philosophy, psychology, […]
