Query: Rheology, and how to stop aging   Recent analytical developments in glass theory are equally relevant to the
understanding of anomalous rheology, with characteristic features such as the
Reynolds dilatancy and the driving-power dependence of the viscosity arising
naturally. A notion of effective temperature based on the
fluctuation-dissipation relation can be introduced in the limit of small
driving power. Within mean-field, the analogue of the Edwards compactivity can
be computed, and it coincides with this effective temperature. The approach
does not invoke any particular geometry for the constituents of the fluid,
provided it has glassy behaviour.
