It is humanly impossible for any individual to master the whole knowledge with all its complexity and diversity. It is of natural world based on facts that is learned through experiment and observations. There are different science to deal with opposite branches of knowledge. These sciences are two kinds , physical and social sciences
The physical science deals primarily with natural inanimate object they are regarded as more precise, exact, and less dubious like Mathematics, Physics, Chemistry, Geography, Astronomy and so much more. The Physical Scientist make us use of scientific method in order to acquire knowledge in different fields. They conduct experiments to verify claims, like facts theories and laws of universal validity in Physical Science and they use different type of research to provide wide scope for doubt and uncertainty. Prediction is not possible, but also easy and accurate. The problem of objectivity can be overcome easily . The relationship between cause and effect is relatively more clear here.
While the term social science is often loosely applied to any kind of study which is concerned with and society but in the strict sense, it refers to the application of scientific method of intricate and complex network of the human relationships and the forms of organization desired to enable people to live and work together in a given society. As what Aristotle says ” man is by nature a social animal ” so in Social Sciences we mean those bodies of knowledge compile through the use of scientific method which deals with the form and mam interaction like political science, history, economics sociology, anthropology and psychology.
To be Social is to interact, to participate in the group of life. All human being live in society, that is to say that every person is a member of social environment.
As a conclusion Social Scientist study the environment in which we lived in as an attempt to understand human society in order to predict how people will interact at a given circumstances.
