History of science, since time immemorial, has embraced clearly defined interdisciplinary methods and perspectives, and other fields of human endeavor are beginning to buy into the pace set by sciences. Understanding science has become a more complex issue of discussion due to the numerous fields of study it embodies. In times past, the idea of science was confined to limited areas, like natural sciences, sociology, theology, philosophy and history. However, other fields like literary & cultural studies, political science, ethnology, and anthropology were added to the long list towards the twilights of the twentieth century. Such additions have successfully transformed science into an object of rigorous and engaging scholarly investigation.The additions mentioned earlier, contributing their quotas to the dictates of science, have blurred its erstwhile defined boundaries, cutting off the distinction between what can be termed as historical and what is not in the definition of the field of sciences as a human activity.In time past, some schools of thought held firmly to their impressionistic and subjective points of view regarding history, emphasizing that science is incapable of being made an embodiment of personal vision branch of literature or that if a nation, church or class that history represents. Be that as it may, science cannot be declared as laying claim to eternal and universal objectivity; rather, it prefers to be assessed as a point of view of the past giving and means of meeting the demands of the present day and the future. This factor justifies history as an integral part of scientific study.
