In June 2000, the Fourteenth Symposium on Thermophysical Properties was held to review the progress of thermophysics over the last 100 years and to look forward to the next century of research and development in thermophysics. The National Institute of Standards and Technology (NIST) provides a special publication online covering the event and including overviews of topical issues from professionals in the field and several brief, invited essays on issues raised in the forum by panelists, audience participants, and other experts in thermophysics. The topics addressed in the 113-page .pdf document include molecular modeling, nuclear waste cleanup, power plants, process and chemical manufacturing, data evaluation, simulations and sensitivity analysis, among others.
