True to the form of the previous four phonon-scattering conferences, the Illinois conference was characterized by lively discussions of traditional subjects, punctuated with new ideas and descriptions of new techniques. A newcomer might think that the subjects of thermal conduction in amorphous materials or the perennial Kapitza resistance problem were in their infancy, as judged by the diversity of viewpoints expressed. Indeed, much progress is being made in characterizing phonon scattering in wide varieties of condensed matter, but descriptions of the microscopic scattering processes are remarkably elusive.
