Coming Events

Tuesday - Thursday, October 7-9, 1996
UIUC LIBRARY'S ANNUAL BOOK SALE
will take place in the East Foyer of the Main Library. Proceeds will be used to purchase special materials for the library collections.
Thursday - October 10, 1996
MATHEMATICS COLLOQUIUM.
Prof. John Sullivan; Conformal Knot Energies and a Higher-Dimensional Generalization.
An energy for knots, invariant under Moebius transformations of the ambient space, was considered by Freedman et al. We will describe this energy and others with similar properties, and discuss how they can be extended to surfaces and higher-dimensional submanifolds. We have performed extensive computer experiments with these energies, and will show some of the results, including a six-minute computer video.
Monday - Wednesday, October 21-23, 1996
LECTURES.
Dr. Richard W. Hamming, The Naval Postgraduate School.
Monday, October 21 Teaching from the Systems Engineers Point of View,
followed by a discussion with graduate students on career choices.
Tuesday, October 22 Mathematics on a Different Planet, or How Arbitrary is Mathematics?
This will be a talk in the series Mathematics in Science and Society.
Wednesday, October 23 The future of Electrical Engineering.
This will be a talk in our Computational Science and Engineering Program, in which the Department of Mathematics is a partner.
