The difference between pure science and applied is incredibly huge when one considers their particular usefulness to society. Pure science is mostly cerebral and experimental but applied science is of totally practical use to society. Technological know-how, medical understanding, microscopic explorations, extra-terrestrial conquests and superstition minimisation are all the dividends of applying science to all manner of problems encountered by human beings. In all societies, developing and advanced, it is the application of science and not mere theory that has made the technosphere so amazing and useful. This is certainly not an attempt to denigrate pure science, whatsoever. One can only apply scientific solutions to everyday and rare problems, big and small if the practitioner or student knows enough pure science, to begin with. It is the application of science that makes tonnes of metal to fly in the sky, incurable diseases curable, summer foods to grow in winter, people to communicate with each other over thousands of miles in real-time, meat to be preserved for months. Pure science and applied science are truly beautiful, even though they can be put to ugly uses.
