Under modern conditions, this requires varying measures of centralized control and hence the help of specialized scientists such as economists and operational research experts. 72. Furthermore, it is obvious that the strength of a country’’s economy is directly bound up with the efficiency of its agriculture and industry, and that this in turn rests upon the efforts of scientists and technologists of all kinds.
