Abstract. We present a new dynamical approach for measuring the temperature of a
Hamiltonian dynamical system in the micro canonical ensemble of
thermodynamics. We show that under the hypothesis of ergodicity the
temperature can be computed as a time-average of the functional,
div(grad H/|grad H|^2), on the energy-surface.
Our method not only yields an efficient computational
approach for determining the temperature it also provides an intrinsic
link between dynamical systems theory and the statistical
mechanics of Hamiltonian systems.
