Autorenporträt

ROBERT HANSON is a Professor of Chemistry at St. Olaf College, in Northfield, Minnesota, USA, where he has been teaching since 1986. Trained as an organic chemist with Gilbert Stork at Columbia University, USA, he shares a patent with 2001 Nobel Prize winner K.Barry Sharpless for the asymmetric epoxidation of allylic alcohols. His interest in thermodynamics goes back to early training at the California Institute of Technology, from which he got a B.S. degree in 1979.  SUSAN GREEN has had the privilege of being both a student and a  professor at St. Olaf College in Northfield, Minnesota, USA, where she was first introduced to the idea of teaching thermodynamics to first-year students. She trained as a physical chemist at the University of Minnesota, USA, studying the vibrational and electronic structure of small metal oxides as well as trying her hand at analytical chemistry.
