The author holds that pure science is primarily concerned with the development of theories (or, as they are frequently called, models) establishing relationships between the phenomena of the universe. Applied science, on the other hand, is directly connected with the application of the working laws of pure science to the practical affairs of life, and to man's increasing control over his environment, thus leading to the development of new techniques, processes and machines. It is evident that many branches of applied science are practical extensions of purely theoretical or experimental work. This shows that these two branches of science are mutually dependent and interacting.
