Both John Servos's excellent discussion of the changing meanings of 'research school', and Kathryn Olesko's challenging article on German physics schools, question the extent to which it is the transmission of tacit knowledge that makes schools significant to historians of science. Any disruption of tacit knowledge, which is for science studies, in Olesko's words, 'a strategic historiographic locus', should be widely studied.
