Sarcasm aside, Roger does have a point. It is very difficult,
bordering on impossible, in general, to specify the microphysical
layer in just such a way as to reproduce a particular macrophysical
phenomenon of interest. This problem is faced everyday by
practitioners of agent-based modelling, and to a lesser extent by
artitifical life researchers (ALife researcher at least have the liberty of
researching any interesting emergent phenomenon without having any
particular emergent phenomenon in mind).
