Many states use complicated algorithms or formulas to assign drivers' license numbers but keep the method confidential. Just for the fun of it, Professor Gallian attempted to figure out how the states code their license numbers. In this talk he will discuss how he was able to break the codes for several of the states. The talk illustrates an important problem-solving technique that is not emphasized in mathematics classes. It also teaches the lesson that sometimes things done just for the sake of curiosity can have applications. (Friday After Dinner Talk)

This talk concerns the problem of traversing an m by n directed grid embedded on a torus so that each vertex is visited exactly once before returning to the starting position. We also consider generalizations and variations on this theme. We conclude with an application to computer graphics. (Saturday Talk)

Graphs of Essentially Equivalent Lattice Paths

A new family of graphs can be defined using the paths of an mn lattice as its vertices. If two paths share (k+1) or more edges, then the corresponding vertices share an edge. We can show when the graphs are connected, when they are trees and the order of the graph. The size of the graph can be determined for n=1, and we are currently investigating the size when n = 2 and when n = 3. We also believe that the independence number of these graphs can be found in polynomial time.(Student presentation.)

Preparing Students for Life After College: An Integrated Professional Development Program

The Department of Mathematics and Computing at Franklin College is piloting a project to create a freshman through senior year integrated professional development program designed to:

This talk will describe the program, its background, and its progress.

Markov Chains and License Plates

People now have the ability to purchase specialty license plates in the state of Indiana. For the past year, we have been trying to formulate a system that would analyze and predict the short and long term trends in the plate sales. We are using variations of Markov Chains and we are in the process of creating a functional transition matrix to model the license plate behavior. We will present the development of the model we have constructed at this point and ask for input. (Student presentation)

The MET report and its recommendations: What, Why, and How?

Since the introduction of the NCTM standards a little over a decade ago, K-12 mathematics teaching in the United States has undergone a fundamental and significant change. As a result, traditional approaches of teacher training at college and universities need to be reexamined. The Conference Board of the Mathematical Sciences recently released the Mathematical Education of Teachers (MET) report to help teacher trainers begin to think about how their courses can prepare future K-12 mathematics teachers for the changing demands of the 21st century classroom. This talk will address four major questions related to the MET report:

1.    What are some of changes in K-12 classrooms over the past decade?

2.    Why do we need to train teachers differently than the traditional approaches?

3.    What are some of the suggestions in the MET report?

4.    What are some exemplary programs that model some of the suggestions in the MET report?


Instead of presenting a long list of recommendations from the MET report, we will discuss some of the broad ideas behind the document that apply to training of elementary, middle grades, and high school teachers of mathematics.

  The Implementation of Dynamic Geometry Software in a Problem-based Learning and Academic Service Learning Environment

In a collaborative project Dr. Besana and I used the dynamic geometry program, The Geometer's Sketchpad, with its intrinsic invitation to an active, discovery-based learning environment as a means to provide a Problem-Based Learning experience for future teachers. I will present the course materials developed and show analysis of data we gathered to investigate the impact of the approach on students' learning performances and attitudes. The Academic Service Learning component of this project, as well as on-site workshops for teachers, will also be discussed.

Harmonic-Type Series

We will take a look at series of the form n = 1[(an)/ n] where { an} is a bounded, repeating sequence of integers; we call these harmonic-type series.  Good examples of harmonic-type series include the divergent harmonic series, n = 11/n, and its convergent ``cousins'', n = 1[((-1) n+1)/ n] = ln2, and n = 1[((-1) n+1)/( 2n-1)] = [(p)/ 4].  We will show a general technique for summing a harmonic-type series, and we will show how the sum of a harmonic-type series is altered under certain term rearrangements.

Mathematical Modeling of Groundwater Flow: A Potentially Interesting Problem

Mathematical modeling of groundwater flow is a topic joining mathematics, fluid mechanics, hydrogeology, environmental science, and computational science. The analytic element method (AEM) is a relatively new technique for modeling groundwater flow. The AEM describes groundwater flow through the introduction of a potential function whose gradient supplies groundwater flux vectors. The AEM can be applied in a wide variety of cases and avoids the need for node-based computational schemes such as the finite difference or finite element methods. Also, solutions produced with the AEM are analytic-the governing differential equation is met exactly, while the required boundary conditions are met approximately. This talk will provide an overview of mathematical modeling of groundwater flow using the analytic element method; applications in both two and three dimensions will be presented.

Views of the Real Numbers and the Continuum

Early approaches to the real numbers were geometric. Mathematicians spoke of the ``law of continuity'' or a continuous variable or magnitude with the image of the real line in mind. In the second half of the 19th century, algebraic or arithmetic descriptions of the real numbers were given by Dedekind, Cantor, and Weierstrass. After developing the theory, each returned to the issue of relating the real numbers to the real line. Dedekind said that while to every point, one can attach a number, it must be taken as an axiom that to each number there exists a point on the line. Cantor agreed on this point; however, Cantor had different ideas about the continuum. To Cantor, a continuum is perfect and connected. Cantor and Dedekind discussed the issue of a continuum and the defining characteristic of the real numbers in a series of letters. To learn of Weierstrass's development of the real numbers, we must rely on lecture notes as recorded by his students. Looking at the notes, we find Weierstrass gives a thorough development of the real numbers. In speaking of the analogy between the real numbers and the line, Weierstrass shows how one associates a real number to a given length, and conversely how one intuitively associates a length to a given number.

26.2 Miles is Long Enough: The Effects of Weaving While Running a Marathon

A marathon is 26.2 miles long, provided the runner stays on the ``true'' path of the race without deviating. However, inexperienced (or tired!) runners often weave from side to side during a long run and thus add distance to their course. This talk addresses the question: How much further than 26.2 miles would a ``weaving'' runner travel over the course of a marathon? The investigation involves an interesting mix of math modeling, trigonometry, calculus (single- and multi-variable), and numerical methods, with some unexpected mathematical twists along the way.

In Memoriam

  Duane E. Deal

  (May 19, 1924 - May 20, 2001)

  Few faculty members can rival Duane Deal's exemplary record of service. Ball State was the mainstream of his life for fifty years. He joined the Department of Mathematical Sciences in 1952. Though his frenzied pace had slowed a bit since his retirement in 1992, there were times when he seemed literally to be everywhere and to do everything - from the Department of Mathematical Sciences to the Theta Chi house to Emens Auditorium to University Gym to the Muncie Public Library to commencement on the Arts Terrace.

  He served on or chaired more than fifty university councils and committees, in addition to serving as administrative assistant, acting chairperson, and chairperson of the Department. He received the university's first faculty service award in 1972. His knowledge and love of history in general, and the history of mathematics in particular, brought invitations to speak at more than sixty local, state, regional, and national meetings and caused him to be selected as a member of the editorial board for the thirty-first yearbook of the National Council of Teachers of Mathematics.

  Mr. Deal's popular column, ``Mathematical Oddments'' in the Indiana Mathematics Teacher, amused and enlightened countless teachers and students. With all of this activity, besides the presidency of the Sigma Zeta Honorary Science Society and every office in the Indiana Section of the Mathematical Association of America, he still found time to be an effective, caring classroom teacher.
