Hello-- I am a Professor Emeritus of Metallurgical Engineering, retired from the Missouri University of Science and Technology, Rolla, Mo, where I specialized in extractive metallurgy and the thermodynamics of materials processing. I presented short courses on subjects related to the above subjects at various annual meetings of TMS and AIST. One of my special interests was the development of software used to model extractive metallurgy processes and adapting this software to CDs that accompany materials engineering textbooks. More recent interests have been writing and editing articles related to thermodynamics for Wikipedia, revising textbooks, and contributing educational articles on combustion for the magazine Industrial Heating.Thermbal (talk) 22:32, 15 November 2018 (UTC)
