Henry Eyring: Statistical Mechanics, Significant Structure Theory, and the Inductive-Deductive Method Douglas Henderson Department of Chemistry and Biochemistry, Brigham Young University, Provo UT 84602, E-mail: doug@chem.byu.edu (Dated: October 22, 2018) Henry Eyring was, and still is, a towering figure in science. Some aspects of his life and science, beginning in Mexico and continuing in Arizona, California, Wisconsin, Germany, Princeton, and finally Utah, are reviewed here. Eyring moved gradually from quantum theory toward statistical mechanics and the theory of liquids, motivated in part by his desire to understand reactions in condensed matter. Significant structure theory, while not as successful as Eyring thought, is better than his critics realize. Eyring won many awards. However, most chemists are surprised, if not shocked, that he was never awarded a Nobel Prize. He joined Lise Meitner, Rosalind Franklin, John Slater, and others, in an even more select group, those who should have received a Nobel Prize but did not. 1 arXiv:1001.4522v1 [physics.hist-ph] 25 Jan 2010 Abstract
