Review of Nugayev's book "Reconstruction of Scientific Theory Change"

A comprehensible model is proposed aimed at an analysis of the reasons for theory change in science. According to model the origins of scientific revolutions lie not in a clash of fundamental theories with facts, but of “old” research traditions with each other, leading to contradictions that can only be eliminated in a more general theory. The model is illustrated with reference to physics in the early 20th century, the three “old” traditions in this case being linked with Maxwellian electrodynamics, Newtonian mechanics and phenomenological thermodynamics. Some modern examples are considered. Key words: Kuhn, Lakatos, Zahar.
