We may think that researches of this kind will only be successful if attention is concentrated, not only on the phenomena of compressibility and dilatation, but also on the calorimetric properties of bodies. Thermodynamics indeed establishes relations between those properties and other constants, but does not allow everything to be foreseen.
Thermodynamics teaches us that life and motion are engendered by an irregular distribution of energy. Entropy an even distribution of energy equals death and stasis. What about the disadvantaged and challenged the mentally retarded, the mentally insane, the paralyzed, the chronically ill? For that matter, what about the less talented, less skilled, less daring?
The concern manufactured among other things steam-turbines, and this young man, having demonstrated in school his particular aptitude for thermodynamics the study of heat and its units in its application to engines, and the like entered the erecting department.
Calculation has enabled M. Van der Waals, by the application of his kinetic theories, and M. Duhem, by means of thermodynamics, to foresee most of the results which have since been verified by experiment.
We must, if we wish to penetrate deeper into details, particularize the hypothesis, and admit, for instance, with Gibbs that we are dealing with perfect gases; while, thanks to thermodynamics, we can constitute a complete theory of dissociation which leads to formulas in complete accord with the numerical results of the experiment.
One branch of the "correlation of physical forces," as it was termed by Grove, was the relation between mechanical power and heat, and the convertibility of each into the other, which, under the name of "Thermodynamics," has become one of the most important branches of practical science.
Already recognized as being possessed of a fine discrimination in matters of engineering moment, especially in thermodynamics as related to turbines, he has but gone up in channels early laid out for him, and indicated to him, in his college days. His direction even then was clearly marked. All he had to do, and all he did do, was to develop himself in this single direction.
Then, in speaking of the law of Thermodynamics, he says: "Any material system which should store energy by arresting its degradation to some lower level, and produce effects by its sudden liberation, would exhibit something in the nature of Life." This, however, is not very precise, for this would hold true of thunder-clouds and of many machines.
A simple illustration of this is the pressure which will blow a cork from an empty bottle when that bottle has been placed near the fire. Here we have pressure, or compressed air, in the bottle produced by heat alone. Having defined compressed air, we must next define heat; for in dealing with compressed air, we are brought face to face with the complex laws of Thermodynamics.
It is in this case alone that can be correctly applied the celebrated demonstration by which Kirchhoff established, by considerations borrowed from thermodynamics, the proportional relations between the power of emission and that of absorption.
