Thermodynamics Symposium hermodynamics is perpetually undergoing “searching reappraisal,”

Tusually for the purpose of de-empiricizing some of the methods of predicting thermodynamic properties. This is simultaneously an indication of the high level of general interest in an essential subject and a symptom of equally general, though intuitively based, dissatisfaction with the available methods of thermodynamics for practical applications. T o many people it seems incredible that a classically exact science should have to be so highly doctored before it is forced to yield numbers of known accuracy that can be put to use. If you doubt the truth of this statement, merely consider the vast imwtment in PVT experimentation around the world. In recent years the general effort of making thermodynamics less ideal and more real has segregated into several smaller attempts to get around the impossible restrictions imposed by classical thermodynamics. We have, for example, irreversible thermodynamics, statistical thermodynamics, the thermodynamics, and so forth. I n several places we have even seen some serious questioning of the bases of classical thermodynamics, though usually without success. The forthcoming I&EC Division Symposium on Applied Thermodynamics searchingly appraises thermodynamics as have its predecessors, but it also has some unique elements that commend it to the attention of the serious professional engineer. In his attempt to include the breadth of thermodynamics, Chairman K-C. Chao has succeeded, but more remarkable is the depth of treatment that he also achieved in making up his program. The credentials of the speakers cannot be questioned in any respect. The subjects to which they address themselves comprehensively treat all the major aspects of thermodynamics from the latest refinements in the well established empirical methods to the most advanced theoretical treatments. To achieve such a program in three days is a tribute to the organizational talents of Prof. Chao and a distinct challenge to the attendees. I t is assured that there will be little to attract a passive listener. But then that is the object of the whole affair-namely, to provide a first rate vehicle for actively interested engineers who want to bring themselves up-to-date in such a vital subject. The prospect for the Thermodynamics Symposium is every bit as bright as it has been for the previous three summer symposia. \.\‘e recommend that registrations be completed as early as possible. Registration information will be found on page 1 2 of this issue.
