‘Where are we when we think?’ Space, time and emancipatory education in galleries

Adult education in art galleries sits on a fault line, at once an apparatus upholding the affirmative aspects of museum culture cultivated by global elites, a propellant in the whirring of an increasingly dislocated set of events on trendy and consumable political themes, and a site for ‘allyship’ and other kinds of radical and socially transformative work. Resurrecting Hannah Arendt’s question,‘where are we when we think?’ this paper explores how we might move from a moment in which the ‘space’ of the gallery is replaced by the ‘time’ of the event (Helguera) and towards embedded space-times that attempt to address contemporary urgencies through situated practices that collectively analyse and respond to conditions. Drawn from examples derived from the author’s practice, the paper argues for the use of popular education and anti-colonial pedagogies in the production of adult education in galleries, suggesting that such processes support groups in collectively naming and thinking through conflicts to re-shape both the galleries in which they have congregated and the worlds beyond their doors. This paper suggests that the re-construction and use of the often forgotten genealogies of emancipatory education are pivotal to doing social justice work in galleries

Action Principle in Nonequilibrium Statistical Dynamics

We introduce a variational method for approximating distribution functions of dynamics with a ``Liouville operator'' \hL, in terms of a {\em nonequilibrium action functional} for two independent (left and right) trial states. The method is valid for deterministic or stochastic Markov dynamics, and for stationary or time-dependent distributions. A practical Rayleigh-Ritz procedure is advanced, whose inputs are finitely-parametrized ansatz for the trial states, leading to a ``parametric action'' for their evolution. The Euler-Lagrange equations of the action principle are Hamiltonian in form (generally noncanonical). This permits a simple identification of fixed points as critical points of the parametric Hamiltonian. We also establish a variational principle for low-order statistics, such as mean values and correlation functions, by means of {\em least effective action.} The latter is a functional of the given variable, which is positive and convex as a consequence of H\"{o}lder realizability inequalities. Its value measures the ``cost'' for a fluctuation from the average to occur and in a weak-noise limit it reduces to the Onsager-Machlup action. In general, the effective action is shown to arise from the nonequilibrium action functional by a constrained variation. This result provides a Rayleigh-Ritz scheme for calculating just the desired low-order statistics, with internal consistency checks less demanding than for the full distribution.Comment: 46 pages, LaTex Version 2.09, tar + gzip + uuencode The tar file contains xyzvar.tex, the LaTeX file itself, and seceq.sty, a stylefile for sequential numering of equations by section.
