Scientists speak of those moments of discovery when all their hard work, all their experimenting, and all their trial and error yield sometimes surprising results.  Hosts Judy Muller and George Lewis chat with three noted researchers about how creativity plays a big part in their science.  Our guests are Philip Bevilacqua, Distinguished Professor of Chemistry and Biochemistry and Molecular Biology at Penn State, Scott Showalter, also from Penn State, Professor of Chemistry, Biochemistry and Molecular Biology; and Kathleen Hall, Professor of Biochemistry and Molecular Biophysics at Washington University in St. Louis.  Our panel was part of a series of "Town Talks" in Telluride, recorded before a live audience at the Wilkinson Public Library.
