   Pure science is primarily concerned  with development of theories(or,as they are frequently called,models)   21 relationships between the phenomena of the universe.When they are sufficiently validated,these theories become the working   22 or principles of science.In carrying out this work,the pure scientist usually disregards its applications to practical affairs,confining his attention to explanations of how and why events occur.  23 ,in physics,the equations describing the behaviour of fundamental particles,  24  in biology ,the establishment of the life cycle of a particular species of insect living in a Polar environment,are said to be examples of pure science (basic research),having no apparent   25(for the moment) with technology,i.e.applied science.

    Applied science,on the other hand,is directly concerned with the application of the working laws of pure science to the   26 affairs of life,and to increasing man's control over his environment, 27 leading to the development of new techniques,processes and machines.Such
