Some methodological and historical considerations in low temperature

Summary

In this paper we study some of the methodological problems associated with the development of the various theoretical schema devised to explain the phenomenon of superfluidity. The physical behaviour of supercooled helium defied explanation in terms of the known atomic laws for helium and their ‘natural’ extrapolations. We show that the basic conceptual difficulties involved were circumvented by the development of intermediate intermediaries through a process of contextual reinterpretation.
