11/15: Richard Cushman
The Twisting Tennis Racket
Abstract: This talk gives a mathematical explanation of the twisting
phenomenon exhibited in the following experiment. Take a tennis racket and
mark its faces so that they can be distinguished. Call one rough and the
other smooth. Hold the racket horizontally so that the amoorh face is up. Toss
the racket attempting to make it rotate about the intermediate principal axis,
which is through the face
and perpendicular to the handle. After one rotation catch the racket by its
handle. The rough face will almost always be up! Thus the racket has made a
near half twist around its handle.

11/22: No meeting this week.

11/29: Bora Ferlengez
The space of almost complex structures on S^6
