In laymen terms, Paradigm Shift is a popular, or perhaps, not so popular shift or transformation of the way we Humans perceive events, people, environment, and life altogether. It can be a national or international shift, and could have dramatic effects -- whether positive or negative-- on the way we live our lives today and in the future.
Probably the best way to look at a paradigm shift is through example, using example of Ptolemy, whose fixation upon a paradigm created problems. Ptolemy, in common with most Ancient Greek philosophers, believed that the earth was at the center of the universe, and that the sun and other planets revolved around it.
