 Gayon remarks that this latter notion of ‘style’ could be replaced by ‘method’ and that ‘the styles discussed here have nothing to do with local styles’. He also remarks that when it comes to local styles the groups that act as sociological support for such analyses are either ‘research groups’ or ‘nations’. There has been much emphasis in recent history of the experimental sciences on such local factors (see, for instance, Gavroglu 1990 for the ‘styles of reasoning’ of two low temperature laboratories, that of Dewar (London) and that of Kamerlingh Onnes (Leiden)).
