It was by the study of heat, and more especially of thermodynamics, that we obtained our conceptions of the science of energetics.
"The Mechanism of Life"

The principles of thermodynamics throw great light on all the phenomena of nature, and it is probable that many valuable applications of these principles have yet to be made; but we shall have to point out the limits of this science, and to shew that many problems in nature, especially those in which the Dissipation of Energy comes into play, are not capable of solution by the principles of thermodynamics alone, but that in order to understand them, we are obliged to form some more definite theory of the constitution of bodies.

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.
