paradigm,i.e., Ptolemaic astronomy, engage in activity that involves solving problems related to the paradigm. In revolutionary science, which occurs rarely, researchers abandon one paradigm, i.e. Ptolemaic astronomy, and embrace another, i.e., Copernican astronomy. Kuhn held the abandoned paradigm and the embraced one to be

The jump from one paradigm to another, he argued, has a sociological explanation, but no strictly rational justification. Kuhn's other works include The Copernican Revolution (1957) and The Essential Tension (1977).
