In short, Thomas Samuel Kuhn (July 18, 1922 – June 17, 1996) was an American intellectual who wrote extensively on the history of science and developed several important notions in the philosophy of science.

Answer 3

Thomas Kuhn is most famous for his book The Structure of Scientific Revolutions (SSR) (1962) in which he presented the idea that science does not progress via a linear accumulation of new knowledge, but instead undergoes periodic revolutions. Kuhn's work has been extensively used in social science; for instance, in the post-positivist/positivist debate within International Relations. Kuhn is credited as a foundational force behind the post-Mertonian Sociology of Scientific Knowledge.
