This is period when science and technology came into place. The elites believed that a country cannot run without putting in place new technologies that are meant to make work easier and assist to solve difficult problems and situations.
As the term itself implies, the postmodern era is so much attributed to the ideas of the total end of the modern movement which had its establishment in the American society for about 100 years. The works which were very common in this time like the renaissance paintings, expressionism drawings, existentialism in philosophy, modern school of theory and the films which had its root cause during the era are now considered patterns of the past which are meant only for flowering and do not have any other important function.

The area of scientific knowledge is worth noting during this time. Jean-Franois Lyotard argues that as far as the issues in fields like painting, architecture and music have so much been used to distinguish between the modern era and the postmodernism era, scientific knowledge is a kind of discourse that has its great developments rooted
