Bird, Alexander (2004). „Thomas Kuhn”. Stanford Encyclopedia of Philosophy. Stanford University — преко plato.stanford.edu. "Not all the achievements of the preceding period of normal science are preserved in a revolution, and indeed a later period of science may find itself without an explanation for a phenomenon that in an earlier period was held to be successfully explained. This feature of scientific revolutions has become known as 'Kuhn-loss'". The term was coined by Heinz R. Post in Post, H. R. (1971), "Correspondence, Invariance and Heuristics," Studies in History and Philosophy of Science, 2, 213–255.
