ABSTRACT
Science has made magnificent progress in the analysis and control of inanimate forces, but it has not made equal advances in the more delicate, more difficult, and more important problem of the analysis and control of animate forces. This indicates the desirability of greatly increasing the emphasis on biology and psychology, and on those special developments in mathematics, physics, and chemistry which are themselves fundamental to biology." It was on the basis of this recommendation that the trustees, in the spring of 1933, voted to make experimental biology the field of primary interest. For, although man remains the measure of all the ends that are being sought, the road toward those goals is determined, not by its classification as human biology, but by its ability to contribute fundamental knowledge of the vital processes which underlie human biology. An example of a physicochemical discovery turned to the use of experimental biology is the application of isotopes as tracers.
