Play It Again, CSAM

by minton on April 18, 2019

It was a weekend of comebacks in sports: Tiger Woods winning the Masters, the Clippers erasing a 31-point deficit against the Warriors, and CSAM returning to Furman. The last item made few headlines, but the Carolina Sports Analytics Meeting at Furman University is a highlight of the year for myself and several students.

Roanoke College had a large presence at this year’s CSAM (other schools well represented included Furman and Davidson). Senior Physics major David Moreau gave an excellent talk on golf analytics, one that prompted a follow-up conversation with ESPN writer Peter Keating. Sophomore Sport Management major Megan Wheeler presented a poster on shot probabilities in Division III women’s basketball. In a different form of comeback, alum Taylor Ferebee (RC ’17) returned to the meeting with an outline of genetic work being done at Clemson University and other research labs. Seniors Emma Blair and Lexi Denning would have also presented posters but they and their posters were at the NCUR meeting in Atlanta. Math professor Roland Minton led the group, which also included sophomore Stat Crew member Jessica Louros and freshman Stat Crew member and Math major Jake Beardsley, who has worked on analyzing March Madness upsets this semester.

The CSAM meeting itself represented a comeback of sorts. Hosted by Furman for four years 2013-2016, this highly successful conference was on hiatus for two years. Roanoke College held the substitute VSAM in 2017; VSAM was also successful, but we are glad that Furman has resumed its leadership. The conference has a great culture of openness to students and researchers at all levels. RC students have taken advantage to gain some great experiences!

Star City

by minton on March 21, 2019

In Agnes Handal’s hometown, Christmas season is a happy time with numerous parades and festivities. Musical groups called scouts come from miles around to march and play their drums and bagpipes, celebrating with local townfolk and tourists of various religious backgrounds.

Agnes, who is a junior actuarial science major at Roanoke College, showed pictures and videos of her home to a group at Salem Presbyterian Church. Her story becomes especially interesting when you realize that her family has been living in the same area for more than 500 years. They live in Bethlehem in Palestine.

For a Christian, walking down Star Street in the path followed by Wise Men, then into Manger Square and Nativity Church would add a huge emotional dimension to the season. This is true for Agnes, who is proud of her Christian heritage. Her siblings all have holy names (Agnes means “lamb”).

Where it all becomes complicated is the political context of Bethlehem. Agnes says her house is a ten-minute walk from Jerusalem, but since she is considered Palestinian she would need a special permit to take the walk. She showed pictures of a nine-foot wall on a border of Palestine and Israel. A distantly-remembered past when the region’s melting pot of Jews, Muslims, Christians, and others learned to co-exist has given way to today’s politically charged power struggles.

Most of this seems to be set aside at Christmas, as Muslims join in the centuries-old traditions surrounding December 25 in Bethlehem. In this historic place, for a brief time each year, people converge to celebrate the past and create hope for the future.

Another Year, Another Pi Day

by rahmoeller on March 15, 2019

Whew! What a week! Not only was it the week right after Spring Break (which is always a tough week), but it also happened to be a very busy mathematical week! Thursday, March 14 was Pi Day! Pi, a mathematical constant, was originally defined as the ratio of a circle’s circumference to its diameter, i.e. circumference = 2π*radius = π*diameter. Did you know that we use the symbol π for pi because it is the first letter of the Greek word for perimeter (or circumference)?

Have you ever heard of a guy named Lawrence (Larry) Shaw? He was an American physicist, among other things, but most importantly for this post, he invented Pi Day back in 1988. Why did he pick March 14? Well, we typically approximate π to 3.14, and so logically one might think, 3 represents the month and 14 the day.

But, there are other dates that could work well for Pi Day: April 5, say. Why? Well, since we begin our year with January, when 3 months have actually passed, we are at April 1. But 14% of April turns out to roughly 4.34 days, which means that by April 5, 3.14 months of the year have gone by. Another possible date could be to choose the 314th day of the year: November 10. In fact, why not celebrate all 3? Heck, someone come up with another day to celebrate π: I’m in!!

How did Roanoke College celebrate Pi Day this year? On Wednesday, March 13, some faculty, several students, and our amazing RC baker baked a total of 58 pies (26 apple, 32 pumpkin), all of which were donated to the Salem Food Pantry.

Then, on Pi Day, we calculated the results of our jar fundraiser. For about 3.14 weeks, we collected donations for the West End Center into jars, which were associated with both math and chemistry professors.

The professor (Dr. Skip Brenzovich, chemistry) whose jar had the LEAST money ($12.42) was pied:

If only you could see Skip’s expression underneath that pie…

And the professor (Dr. Richard Keithley) whose jar had the MOST money ($92.01) was pied:

Call from crowd: “Dr. Keithley, you have some hair in your pie…”

We raised a total of $315.83 this year!! Thanks to all who donated to the West End Center!

We already are counting down the days until Pi Day comes around again…so, April 5 anyone??

 

Special thanks to the Salem Kroger for a generous gift card donation; to Lavelle Glenn who baked the pies to perfection in the scary ovens; to faculty members Hiba, Bonnie, and Claire for their efficient work in peeling 40 lbs of apples; and to RC students Ricky, Andrew, Anna, Sara, Sophie, Lydia, Gavin, Sam, Gideon, Abbi, Robert, and Cody – all y’all did all the hard work and are absolutely incredible!!!

Fuzzy Memories

March 14, 2019

Some of the reminisces that follow are true, but some are only partially true. That statement may seem obvious given the unreliability of human memory. However, in terms of mathematical logic (and, after all, I am writing about a mathematician) the phrase “partially true” may seem nonsensical. My intention, as I hope you will see, […]

David Moreau will graduate in May as Stat Crew’s GOAT. If you’re not familiar with sports lingo, that means Greatest Of All Time. David’s four years at RC coincide with Stat Crew’s four years of existence, and he has played a major role in the success and development of this experiment in academic-athletic collaboration. At […]

Fun With Physics and Life

December 11, 2018

I was saddened to learn that Dick Minnix died on November 28. Dick was a hero to me, and I suspect many others, and truly had a large positive effect on physics education. I first met Dick in California at a large conference for community college math professors. Dick was there as a keynote speaker […]
