Off on a Tangent 17.1

Welcome!

Welcome to a new edition of Hope College Mathematics Department’s newsletter, Off on a Tangent. While this is not our first edition, it is the first edition that is published on Hope College’s blog network. We published previous editions on our own server (which will soon be put to rest) for the past 16 years and even published hard copies in the years before that. But now it is time for a change. Even though we are moving the process of delivering the math department news to a blog, we will continue to publish an issue about every fortnight (or every other week). In doing so, we will try to keep you up on the news of the department (as well as some interesting math news outside the department), let you know what colloquia will be presented in the coming weeks, and provide you with our famous Problem of the Fortnight.

Colloquium

The first mathematics department colloquium will take place in about two weeks. Here are the details.

  • Title: The Intel Math Experience: An Instructor’s Perspective
  • Speaker: Dr. Erin Militzer, Ferris State University
  • Time/Location: Thursday, Sept 20 at 4:00pm in 1019 Schaap Science Center

Abstract: Intel Math is an 80-hour professional development course in mathematics content for K-8 teachers. The program was adapted from the Vermont Math Initiative developed by Dr. Ken Gross. The course is collaboratively taught by a practicing mathematician and a mathematics educator. One of the goals of Intel Math is that teacher participants deepen their own understanding of math through problem solving.

Intel Math is designed to close the gap between insufficient mathematics training of elementary school teachers and the demands of the contemporary mathematics classroom (Kenneth Gross) and places emphasis on deepening the teacher participants’ understanding of core K-8 mathematics concepts.

In this interactive presentation, I will share what we do during the program, what the teachers accomplish, some of the unique content that encompasses the Intel Math experience, and statistics on a specific study of Intel Math in northern Michigan. Please join me to learn more about what teachers are doing with their Saturdays and summers.

Ice Cream and Fun

Please join the mathematics faculty and fellow math students for the Ice Cream and Fun event this Friday, September 7. It will be located on the Van Andel Plaza that is in front of the Schaap Science Center. In case of rain it will be held in the Science Center’s Atrium. Come enjoy delicious ice cream, some fun games and get to know your fellow math students and faculty.  When, you ask? We will gather at π p.m. and plan for the fun to last until π+1 p.m. Or for those not familiar with such times, 3:14 p.m. to 4:14 p.m.

Student research projects receive national honors

Two projects written by Hope students have been honored in the Undergraduate Statistics Project Competition. The awards, just announced, came from entries in the spring 2018 season. The projects came from students in Dr. Yew-Meng Koh’s Math 311 class.

First prize in the competition went to Alyssa Goodwin, Sam Heilman, and Leah Krudy for their project, “Effects of Color on Heart Rate” and the third prize award was won by Maya Smith and Adair Cutler for their project “Tuition to Test Scores: A Statistical Analysis.”

More information about the contest as well as the winning papers can be found here and Hope’s press release can be found here.

Hope student presents at JSM in Vancouver

The following was written by Noah Kochanski as a reflection of his participation in the Joint Statistical Meetings last month.

This past summer, I was given the opportunity to travel to the Joint Statistical Meetings (JSM) in beautiful Vancouver, British Columbia.  I presented research that I did with my mentor, Dr. Yew-Meng Koh, on Predicting Disease Incidence.  It was extremely nerve-racking presenting to other JSM attendees, the majority of whom were either professors or PhD candidates.  However, I was overwhelmed at how supportive the group was.  We were able to attend a plethora of presentations in Statistics that ranged from how the New York Times uses Statistics to using Statistics in the food industry.  The JSM was extremely developmental for me to network with many researchers as well as broaden my scope of what careers can be fulfilled with a degree in Mathematics and Statistics.  When not attending the conference, we were able to sight-see in Vancouver and explore many local restaurants.  The entire trip was a fantastic experience. I would like to thank the Michigan Space Grant Consortium for their support of my research and to Dr. Yew-Meng Koh for being my mentor this past year.

Problem of the Fortnight

Let 1 = a1 < a2 < a3 < … < ak = n be the positive divisors of n in increasing order.  For example, if n = 12, we have a1 = 1, a2 = 2, a3 = 3, a4 = 4, a5 = 6, a7 = 12.

If n = (a3)3 – (a2)3, what is n?

Odds are, you’ll have fun with this one – even if you don’t get it!  If you do crack this one, drop your solution (not just the answer) in the Problem of the Fortnight slot outside Professor Mark Pearson’s office, which is room number 212 in The Werf, by 3:00 p.m. on Friday, September 14. As always, be sure to write your name and the name(s) of your math professor(s) — e.g. R.U. Shurr, Professor S.I. Yam — on your solution.
