If superconductors change as fast as possible as they pass through a phase transition,then the initial domain structure is constrained by causality. We shall see that Josephson junctions do, indeed, display such behaviour. However, we shall argue that causal bounds arise through the Gaussian nature of the order parameter, which can be thought of as a consequence of instabilities growing as fast as possible.

Knappett C, Evans TS, Rivers RJ, 2008, Modelling Maritime Interaction In The Aegean Bronze Age, Antiquity, Vol: 82, Pages: 1009-1024

The authors raise spatial analysis to a new level of sophistication – and insight – in proposing a mathematical model of imperfect optimisation to describe maritime networks. This model encodes, metaphorically, the notion of gravitational attraction between objects in space. The space in which this interaction occurs is the southern Aegean in the Middle Bronze Age, and the objects some of the main 34 sites we know about. The gravitational potential, more sophisticated than in Newtonian physics, is interpreted as a social potential whose equilibria, sampled statistically, determine networks with settlements of particular sizes and links of particular strengths. The model can be tweaked by giving different relative importance to the cultivation of local resources or to trade, and to show what happens when a member of the network suddenly disappears.
