    "abstract": "We overcome one of Bell\u0027s objections to `quantum measurement\u0027 by generalizing\nthe definition to include systems outside the laboratory. According to this\ndefinition a {\\sl generalized quantum measurement} takes place when the value\nof a classical variable is influenced significantly by an earlier state of a\nquantum system. A generalized quantum measurement can then take place in\nequilibrium systems, provided the classical motion is chaotic. This paper deals\nwith this classical aspect of quantum measurement, assuming that the Heisenberg\ncut between the quantum dynamics and the classical dynamics is made at a very\nsmall scale. For simplicity, a gas with collisions is modelled by an `Arnold\ngas\u0027.",
