a true scientist, with no thought of its financial results. This achievement of Perkin stands out as one of the great discoveries of chemistry. And the story of Mauve shows how science has led the way for industry, just as the story of soda shows how industry has pointed out the way for science.
Many more stories of the victories of scientific industry could be told. Much has been done. But the chemist does not live in the glory of the past. He lives in the possibilities of the future. Every advancement of the past has opened up many fields of possibilities. If much has been done, much more remains to be done. And the work of the future will require the services of the scientist more than did the work of the past. Those problems whose answers were obvious, have all been solved. The problems of today are deep ones; they require all the ingenuity, all the ability that the trained chemist can bring to bear upon the problems. And they will all tend to increased efficiency.
While chemistry is a fundamental science, while it covers such a variety of subjects, while the total amount of its established facts is indeed enormous, nevertheless, it must be said with frankness that this vastness is made up for the most part by details and more or less isolated facts and ideas. Chemistry can boast of remarkable achievements. But the greatest achievements are yet before it. And the reason is this: Chemistry is not yet a really unified science. The real fundamentals which will string together all of the isolated facts and ideas, material of which the chemist has, indeed, reason to feel proud, are for the most part lacking. That is why the future is so much larger than the past. And that is why the world can expect from the chemists much greater achievements in the future than it has seen accomplished in the past, great as they have been.
In the most fundamental terms, chemistry concerns itself with the changes which the different kinds of energy
produce upon matter. Chemistry concerns itself with two things, energy and matter. And yet chemistry must admit that it does not know the nature of matter or the nature of energy. And not knowing, it cannot appreciate.
In this direction lie the achievements of the chemistry of the future. As the nature of matter and the nature of energy gradually unfold themselves to the advances of chemical investigation, remarkable possibilities for future development are disclosed. We are beginning to see how really wasteful we have been. The frightful wastes which the movement toward the conservation of our natural resources has called to our attention, sink into utter insignificance when we consider what we have lost on account of our ignorance. We are just beginning to appreciate our wastefulness of chemical energy. A piece of coal, for example, has in it the possibility of doing ten times as much work as it is doing now. A piece of radium has stored in it an almost infinite amount of energy. How to change this internal or chemical energy into the other forms of energy with which we are familiar, into heat, or electricity, or ordinary mechanical energy, that is the problem of the future. The utilization of this vast amount of potential energy that is stored up in all forms of matter, the harnessing of it in the service of humanity, this is the problem which confronts the chemist. It goes down to the very fundamentals of his science.
But the start has been made. The point of the wedge has already found entrance. The discovery of radium, and the study of its decompositions, has opened wide our field of vision. The problem must yield, as the blows of chemical investigation fall upon the wedge and drive it home.
Chemistry has always been a utilitarian science. Its results have always been at the service of humanity. And if we can judge the future by the past, even discounting for the enthusiasm of the chemist, we can forsee improved
processes which will reduce our present wasteful methods; we can see new processes making for us such things as india rubber from starch, for which we must now depend upon the bounty of nature; and we can dimly see the time when we shall be able to utilize some of that energy which is hidden away in the recesses of matter, and whose vastness we have just begun to appreciate.
