discovery of truth and its application to human need. Its
scope is as wide as the range of influences, chemical, physical,
biological, and economic, which affect technology.
The effects of the influence of scientific investigation on
behalf of technology are so broad and beneficial that they
are interwoven intimately with every-day life and contribute
constantly to human progress. Industrial research is one
of the greatest gifts of science to mankind.
