According to Thomas S. Kuhn's seminal work on "the structure of scientific revolutions" (1962)(1), a paradigm is a set of universally recognized scientific achievements that, for a time, provide model problems and solutions for a community of practitioners. A paradigm is a theory that is accepted by the mainstream of researchers and considered as the best available explanation for phenomena observed in the field.
