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 multicandidate 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.

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?" A Guide Dog in My Classroom

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 onethird 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 simple answer. Math Enables the Disabled
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 noncollinear 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. Learning Precalculus and Calculus with the TI89
