Applications Masquerading as Theory - A History Mystery
What is an application? What is theory? How do you tell which is which? We will see that
many of the most important applications are rooted in the historical development of the
function concept. This may well challenge your concept of an application and raise questions
about what you are teaching. Then...a very scary mystery.
|11:00 – 11:55 AM||Mathematics of Choice: How
did W get elected anyway?
Sandra Monteferrante, Dowling College, Oakdale, NY
A discussion of a number of recent and historical examples of multi-candidate plurality
elections which result in unexpected, perhaps even devastating, outcomes. We show, by
example, how election results may differ depending on the method of counting votes (e.g.
plurality, pairwise comparison, runoff election, Borda count and Approval voting). Properties
of voting methods: Condorcet winner criterion, monotonicity and independence of irrelevant
alternatives are examined along with Arrow’s theorem. Saari’s geometric model and
decomposition theorem are presented and used to compare alternative voting methods.
Finally, voter sincerity and strategic voting are examined in the context of the remarkable
Gibbard and Satterthwaite result.
Building a Multitask Model for Problem Solving in Elementary Algebra

|1:05 – 2:00 PM||Why Your Computer Modem Needs
to Know Trigonometry
Steve Bast, Prince George's Community College, Largo, MD
The end of the 20th century was the beginning of the Information Revolution. This
presentation will show how trigonometric functions are used to describe electronic
data signals. It will also provide insight to answer the question: "What is 'bandwidth'
and why is it important?"

The Next Mathematics Reform Movement
|2:05 – 3:00 PM||Map Neighbor Counts
Gary Simon, NYU Stern School of Business, NY
The state of New York has five states as neighbors: Vermont, Massachusetts, Connecticut,
New Jersey, and Pennsylvania. Is there any mathematical regularity to these counts of
neighbors? The following conjecture, slightly rephrased, appeared in a recent article on
spatial analysis: Experience with geographic maps has indicated that, on average, interior
regions will have six neighbors, while regions on the outside border will have four neighbors.
Furthermore, approximately one-third of the regions in any map can be expected to be on
the outside border. We will provide a simple response to this conjecture. Geographic
maps can be arbitrarily complicated in theory, but the reality is that most maps permit a very

Y2M: Yes to Mathematics
|3:05 – 4:00 PM||The "Minimal Point" for a set
of Web Points
Allen Barnes, Queensborough Community College, Bayside, NY
I will start by examining a set of 3 non-collinear points and the point which is the minimal
total distance from these 3 points. Next I will do the general problem for n points. In this
presentation I will attempt to prove some conjectures regarding the "minimal" point P.
