University of Minnesota-Duluth will host the MAA-NCS Fall Meeting, October 19-20.
A program for the Fall 2012 meeting will be posted approximately one to two weeks on the MAA-NCS website prior to the meeting.
Title: Polynomials, Ellipses, & Matrices: Three Questions, One Answer
Abstract: Given two points a, b in the unit disk, when is there a cubic polynomial with roots on the circle with a, b as critical points? I'll describe the connection between this question and two others, one geometric and another concerning matrices, and give the one concise answer for all three questions. The result and its proof extend very naturally to any finite number of points by using a specific type of rational function, called a finite Blaschke product, both as a proof tool and as a link between the three scenarios. This work was the culmination of an undergraduate research project and honors thesis at Bucknell University under Professor Pamela Gorkin.
Title: Getting Undergraduates Involved in Research
Abstract: Although involving undergraduates in research has been a long standing practice in the experimental sciences, it has only been fairly recently that undergraduates have been involved in research in mathematics in significant numbers. In this talk I discuss in general terms such things as how faculty can get started in involving undergraduates in research, the benefits of undergraduate research to faculty and students, how to find suitable research problems, and what is considered to be undergraduate research.
Steve Kennedy, Carleton College
I represented our section at the Board of Governors meeting at Mathfest in Madison in August. That meeting (chaired by MAA President Paul Zorn from our section) introduced us to a new slate of officers as Bob Devaney was introduced as President-Elect and Jenny Quinn and Lloyd Douglas began their terms as Vice-Presidents. Michael Pearson, the new Executive Director as of February 1 was also in attendance.
As usual much of that meeting focused on the financial situation of the Association. We learned that 2012 will be the eighth consecutive year that the MAA has run an operating deficit. It is unsustainable in the long run to do that every year and we need to find ways to run a surplus on occasion. The board decided to endorse several business investments proposed by MAA staff designed to potentially increase revenue in the future. In particular there are plans to increase the revenue streams from the books program and the American Mathematics Competition as well as to develop course packages and e-texts that can be delivered over the Web. You might see the effects of some of those business practice changes soon.
The Board also approved a resolution endorsing double-blind refereeing in the MAA journals. This was a bit more controversial than I expected. There is not much evidence of bias in the the refereeing for our journals, but many folks argued that adopting double-blind reviewing would eliminate the perception that there could be any. Your governor believes that, given that there are members of the Association who believe there might be such a bias and given the evidence I've seen of implicit bias, the gain to the Association of adopting double-blind reviewing outweighed the potential cost (the increased ease of refereeing if the referee knows the author's identity). I voted accordingly.
Mathfest in Madison was a blast. I heard great lectures by Bernd Sturmfels, Amie Wilkinson, Robert Ghrist, Sylvia Bozeman and others. I heard a bunch of great ideas for new things to try in the classroom. Madison was beautiful (and full of good restaurants). And the MAA Players (including our own Paul Zorn) put on an incredible show.
I hope to see many of you in Duluth.
Dan Kemp, South Dakota State University
Welcome back to what I expect to be an exciting and interesting year. I attended the Section Officer’s meeting at MathFest this past summer and there was nothing terribly important to report. The MAA does have a new executive director, Michael Pearson, who many of you may remember as a long time MAA staff member.
The Fall NCS meeting will be at UMD and I hope to see many of you there. Our featured speaker on Friday night will be Beth Skubak from the University of Wisconsin. She is the co-author of a wonderful paper that appeared in the June-July, 2011 issue of the AMM. Our Saturday morning speaker is no stranger to us: Joe Gallian will be telling us about undergraduate research. Of course there will also be other wonderful talks provided by you as long as you get your proposal submitted by 5:00 p.m. on Friday, October 5, 2012. See the section website (http://sections.maa.org/northcen/) for more information.
Our section will honor members with a Distinguished Teaching Award and Distinguished Service Award at the spring meeting at Gustavus Adolphus College. Please be thinking about your colleagues you would like to nominate for these awards. See the section website for more information and nomination forms.
We will also honor several other members by electing them to office. Several NCS offices will be open this year. If you are interested in serving the NCS and therefore the MAA please get in contact with myself or any of the other section officers. Again, see the section website for all their names and contact information.
Dale Buske, St. Cloud State University
As usual, the North Central Section enters the new academic year in good financial shape. I will soon be sending out letters to the section's department chairs asking your institutions to become institutional members of the NCSMAA. Last year 19 colleges and universities became institutional members raising a total of $475 to support Section NExT activities. Institutional memberships are again only $25 a year.
As in previous years, student speakers at this fall's meeting can request reimbursement for up to $100 in travel, lodging and meal expenses. To receive funds they should fill out a reimbursement request form which can be downloaded (here) and give it to me at the meeting.
Lastly, I just want to remind members that the book sale at the fall and spring meeting is no longer “cash and carry.” Instead, the book sale is an opportunity to browse and order at a discount rate (during the meeting only). All books are mailed to you shortly after the meeting. The NCSMAA also receives a commission on these sales. I hope to see many of you at the fall meeting in Duluth.
Aaron Wangberg, Winona State University
The section continues to be active with students at regional and national conferences. At MathFest in Madison, Wisconsin, sixteen students and faculty from the NCS-MAA enjoyed lunch on State Street (see picture). The section will again organize a lunch at the Joint Mathematics Meetings again in January. We are planning a student activity for the fall meeting, and together with the Pi Mu Epsilon conference, we will be sharing an open math problem designed for individual math clubs to complete and present at the spring Pi Mu Epsilon conference held at the College of Saint Benedict and Saint John’s University.(lunch at MathFest)

We have added three new faculty members in the Department of Mathematics and Actuarial Science:
Prof. Eric Rawdon is a co-author of a paper published in the Proceedings of the National Academy of Sciences, entitled: Conservation of complex knotting and slipknotting patterns in proteins. Abstract: While analyzing all available protein structures for the presence of knots and slipknots, we detected a strict conservation of complex knotting patterns within and between several protein families despite their large sequence divergence. Because protein folding pathways leading to knotted native protein structures are slower and less efficient than those leading to unknotted proteins with similar size and sequence, the strict conservation of the knotting patterns indicates an important physiological role of knots and slipknots in these proteins. Although little is known about the functional role of knots, recent studies have demonstrated a protein-stabilizing ability of knots and slipknots. Some of the conserved knotting patterns occur in proteins forming transmembrane channels where the slipknot loop seems to strap together the transmembrane helices forming the channel. Eric is currently on sabbatical.
Prof. Mike Axtell is Co-PI on NSF grant #1225566. Abstract: This project team is building on an earlier effort that prepared the groundwork for an "overhaul" of the traditional three-term calculus course to better serve the needs of all STEM students, beyond just those in the traditional engineering and physical sciences track. The central innovation is to move topics and conceptual coverage needed in upper-level STEM courses into the first two terms of the traditional three-semester sequence. The PIs hypothesize that such a tactic has several beneficial consequences: i) Calculus 2 becomes an attractive "jumping-off" point for students in biology and chemistry; ii) a natural progression of difficulty throughout the full three-course sequence results; and iii) there is room in Calculus 3 to complete vector calculus through Stokes Theorem and the Divergence Theorem. In practice re-sequencing the topics involves a number of changes, including: 1) an early introduction to multivariate calculus, vectors, and sequences; 2) a postponement of infinite series; 3) an early, although brief, treatment of matrices; and 4) the de-emphasis, deletion, or redistribution of a handful of other topics. Primary activities of this project include developing supporting course materials and assessments, large-scale beta-testing of the full three-term sequence and assessing its effectiveness and impact at a variety of partner institutions, engaging in further dissemination of project findings and results, and building support for wider implementation of these ideas.
MathFest 2012 Student presentation award given to two St. Thomas students: Two CSUMS research students, Jack Stangl, Aaron Rodriguez have won the Andersen prize, presented at Mathfest by BioSIGMAA for the best presentation in mathematical and computational biology.

Designed for new college and university faculty in the mathematical sciences, Section NExT (New Experiences in Teaching) is a professional development program that addresses the full range of faculty responsibilities including teaching, scholarly activities, and service.
Each year, applications will be solicited for new MAA-NCS Section NExT fellows to serve for a two year term. We will accept applications from faculty who are within the first four years of beginning full-time employment with teaching responsibilities at the college or university level. The application consists of a short personal statement and a letter of support from the department chair, guaranteeing financial support for transportation, meals, and lodging at the fall and spring meetings of the North Central Section.
The MAA-NCS Section NExT will meet Friday, October 19, 2012 at conference sight with Marshall Hampton from University of Minnesota-Duluth. Details about the MAA-NCS Section NExT program and its fall meeting will be updated at http://sections.maa.org/northcen/secNext.html.

Or go to our web site http://www.csbsju.edu/Mathematics/Pi-Conference.htm.
This spring, we are please to announce that our guest speaker is Annalisa Crannell from Franklin and Marshall College. Her talk on Friday will be "Math and Art: The Good, the Bad, and the Pretty" and her talk on Saturday will be "In the Shadow of Desargues". Please see our website for further details of the the talks: http://www.csbsju.edu/Mathematics/Pi-Conference.htm.
Two evening CAM talks. Both talks are in the 3M Auditorium (OWS 150) at 7:30pm
Abstract: The mathematical idea of chaos has stimulated a range of artistic endeavors from Tom Stoppard's play Arcadia to the movie "The Butterfly Effect". We begin with a general (and gentle) introduction to chaos - what it is and is not and why these ideas might be significant in general mathematical education. We conclude with some visual illustrations of chaos and show how ideas from chaotic dynamics and symmetry can sometimes lead to striking images which in turn can illuminate the original mathematics.
Abstract: A common misconception is that raindrops take the form of teardrops. In fact, they tend to be nearly spherical due to surface tension forces. This is an example of how at small scales the tendency of molecules to adhere to each other is the dominate effect driving a fluid’s motion. In this talk we will explain how surface tension arises from intermolecular forces. We will also examine some examples of the behavior that can occur at small scales due to the balance between fluid-fluid and fluid-solid forces with applications as varied as understanding how detergents help clean clothes to the design of fuel tanks in zero gravity environments.
