and Philosophy of Science**

**Donut Power: Mathematical Consequences of a Torus**

Patrick Hall, Townes Science Center

March 1, 2010

2:00 PM

(please note the revised time)

Mathematically, a torus can be represented by the surface of
a donut. While it may sound tasty, it is not clear of what value,
or even interest, a torus can be. As shown in this lecture, expect
it to explain all sorts of mysteries ranging from problems of
vision, capturing emotions, the reason there are 435 representatives
in the US Congress, and, should time permit, all sorts of other
applications.

**Did Your Group Elect Whom They Really
Wanted?**

Shaw Hall, Younts Conference Center

In university clubs, in social groups, in fraternities and sororities,
in legislatures, in our country, we have elections to select our
leaders, or maybe to determine what kind of pizza to order. But,
will a group elect whom or what they really want? Not necessarily.
Instead, subtle mathematical features of standard election rules
can force the outcome to be what most voters do not want. How
about the way in which basketball teams are ranked (which affects
the “March Madness” seedings), or figure skating,
or gymnastics judged; can the rules affect the outcome? Some of
you will leave worried that the "wrong person won" in
a recent election that was dear to you.
