PASSAGE TWO
Industry and government have learned that research is one of modern man's most important tools -- a tool that creates new products, new weapons, new cures for diseases, new services, new demands, and new wealth. The return on the research dollar is so great that industry and government are increasing, year after year, the amount devoted to research and development. By 1959 the total had reached an annual rate of $10 billion; it has been increasing since then.
There is so much evidence of the usefulness -- often the quite unexpected and unpredictable usefulness -- of new and fundamental knowledge. It is now the opinion of scientists that basic research findings almost always turn out to be useful. In addition to the general social usefulness of new knowledge and the basic research that produces it, industry profits directly from participation in basic research. Industry should engage in basic research in order to be better able to understand basic findings wherever made and to appraise them in terms of their usefulness. A knowledge of fundamental scientific theory is necessary to guide practical research; such knowledge extends the range of understanding and usefulness of research
findings, whether those findings are initially classified as basic or applied. The same principles apply to government laboratories.
This, then, is one of the reasons for emphasizing basic research: it brings understanding, and understanding is useful. In fact, it has often been said that basic research is the most practical research.
