New Frontiers in Chemistry
Twenty-first-century chcmistry has narrowed into units such as instrumental analysis, biochemistry, chcmical engineering, and colloids. Chemistry has progressed from an assembly of facts to a statement of laws, and thermodynamics of chcmical reactions to a study of atomic structure. It is also an age of practical applications which contribute to an improved standard of living. Man has learned to surpass nature as he explores the methods by which living matter is produced. To create a better environment, empirical studies of the past have been replaced by an assurance that any type of matter may be synthesized or analysed with time and effort.
The great frontiers of our world and our universe that await the explorer and the pioneer of the beginning of the twenty-first ccntury arc scientific rather than geographic. The past achievements of chcmistry, the “miraclc” drugs, the superior explosives, the new plastics, the synthetic fibres, the improved gasolines, and the rocket fuels, have received great publicity, but much remains to be done. New types of matter, new applications of known principles, and — most important of all — further correlation and interpretation of known facts and the development of new and more general principles await the coming of new scientific workers with energy, talent, and good training. In addition, there arc great opportunities for those who would apply to the benefit of mankind die findings of scicncc. Cures for cancer and other human ills are needed, as arc new materials for construction to meet the needs of our daily life, better fabrics, stronger metals and plastics, and better sources of energy. As we live in the spacc age, new chcmical problems confront us, and the great problem of the chemistry of the living cell is still with us, the promise for the future is unlimited.
