Dr. Wangberg Featured in the Post
Dr. Aaron Wangberg's use of 3-D manipulatives in Multivariable Calculus were highlighted in the Winona Post:
With three-dimensional physical models, students at Winona State University (WSU) are learning multivariable calculus in a new fashion that involves drawing on the surfaces to help identify and work with different mathematical concepts before formally learning about them. The homegrown models have been shared with institutions throughout the U.S. as well.
Aaron Wangberg is a professor of mathematics at WSU who collaborated with students and engineering department faculty members on the making of the models and has used them to help students learn multivariable, or three-dimensional, calculus. The surfaces are dry erasable and large enough for multiple students to use as a common workspace on which to draw as they work through math problems and interpret what factors such as the height and the slope mean, Wangberg explained. ... continued

Dr. Duncan's Research Celebrated
Dr. Jacob Duncan's work on mathematical modeling of addiction has been featured in numerous media outlets.
From the Winona Post:
Duncan and two co-authors, psychology professor Teresa Aubele-Futch and mathematician and statistician Monica McGrath, recently published an academic paper in the Society for Industrial and Applied Mathematics Journal on Applied Dynamical Systems explaining how a similar mathematical model used to predict pine beetle outbreaks could be useful in treating addiction. “We came up with a frequency prediction that we hope could be used by doctors or clinicians in the field,” Duncan said. “When you know you’re about to relapse again, you can take certain steps to prevent it,” he explained.
Normally, ecology and psychology researchers do not overlap too much. “You wouldn’t think there would be similarities,” Duncan said of the pine beetles and addiction. “That’s the nice thing about mathematics. You can find one equation that can describe one phenomenon, and it may do a really good job of describing another.”

Picking your NCAA Bracket with Linear Algebra
Dr. Aaron Wangberg
Winona State University
Abstract: How do you pick your NCAA Bracket? Do you value home wins, early season games, and blowouts against Division II and III foes? Or is it better to base everything on the last five games of the season? Bring your computer to fill out your NCAA Bracket and hear the math that has helped WSU Linear Algebra students finish in the top 10% of ESPN's Bracket Challenge.

Squigonometry  Dr. Bill WoodUniversity of Northern Iowa |
| The trigonometric functions cosine and sine report the coordinates of a point on the unit circle at a given angle. The circle and its associated functions have perfect symmetry, which we will study by seeing what happens when we break it. The Euclidean unit circle has equation x^2+y^2=1, but we will change the 2's to p's in the distance function and study the curve with equation |x|^p+|y|^p=1. As p gets larger, the circle flattens out and looks more and more like a square; we thus call these curves "squircles." We will look at the analogues of the trigonometric functions in this family of geometries, called p-norms, and explore some interesting connections to special functions, calculus, and number theory. |
Distinguished Lecture Series
Session 1
Sunday Feb 24, 3 pm, Stark 103
Visualization for Effective
Communication
Scientists usually believe that good and clear design consists just of “beautifying” their charts, graphs, and maps. This should be an afterthought, as what truly matters is to “show the data”. This session explains why reasoning about design decisions is as important as reasoning about the data we present to audiences.
Session 2
Sunday Feb 24, 7 pm, Stark 103
How Charts Lie: Getting Smarter
About Visual Information
Graphic designers, data analysts, and journalists are taught that “a picture is worth a thousand words”, that we should “show don’t tell”, and that charts are “intuitive” and useful to “simplify” information. This talk explains why these myths, if taken at face value, are wrong and dangerous, and what we can do to become better readers and designers of graphics.
Session 3
Monday Feb 25, 12pm, Gild 155
Engagement and Future Trends
in Data Communication
Visualization is a language in constant evolution. This session will focus on how designers of visualization can make their graphics more attractive and engaging, and on several potential futures of data communication.
