Show 69 to the new electron microscope for their investigations. In addition, Eyring had an opportunity to work closely with Dr. Irving Langmuir, who had been assigned the production of smokes. The results of their inves- tigation quickly satisfied them that there were no more penetrating smoke sizes than those which they were already aware of. said of this work: Eyring later "Probably the most important result of such an inves- tigation is the psychological relief upon learning what the real dangers are and of getting rid of the 'bogies' that keep thoughtful people from sleeping well."38 When the U.S. entered the war in l94l, Princeton became actively involved in a war training program for industry. As part of this pro- gram, Eyring taught night courses at Newark and Princeton in chemical thermodynamics and quantum mechanics-statistics to those people involved 'with specific war related industries. He also assisted in teaching advanced physical chemistry courses at Newark and Elizabeth, New Jersey. Course work, which extended throughout the war years (l94l-l945), consisted of two three-hour sessions in the evening each week for a period of twenty weeks.39 Toward the end of the war he began consulting with the U.S. Navy and other scientists on high explosives. On several occasions he con- sulted with the famed professor Albert Einstein on this research.40 Again his absolute rate theory was an important aid in understanding the violent reactions associated with explosives. Eyring and three of his graduate and post-graduate students, George Duffey, Ranson Parlin and Richard E. Powell, developed a mathematical model to explain detonation. The model later became known as "the curved front theory."41 The sen- sitive nature of this work during the war delayed the publication of |
