Excerpt from Chemistry in the Service of Man But the end and aim of chemistry is not merely material. Chemistry offers its contribution also to the deeper interests of the human mind. Occupied as he is with the study of material substances and of the marvellous transformations which he is able to bring about in them, the thinking chemist is forced to look below the surface of things and to seek an answer to the fundamental questions relating to the ultimate constitution and structure of matter, and to the forces which govern the changes and transformations which he observes in his laboratory, or which are wrought out in the larger laboratory of Nature. The study, not merely of the products but also of the principles and laws underlying the processes of chemical change, forms the work of the modern chemist. 'in its wider sweep, chemistry ignores the conventional and artificial frontiers which mark it off from the other branches of science, more especially physics; and in the last quarter of a century there has been no more fruitful region of experimental and speculative activity than that common territory where the sciences of chemistry and physics overlap.
