Abstract
A Foucault pendulum may be maintained indefinitely by parametric excitation, but as a consequence of imperfections in its construction, seismic noise and other perturbations it is liable to precess at other than the ideal rate. It has been suggested by Braginsky

The present analysis reveals serious problems in addition to those they considered, but indicates how parametric excitation helps to overcome them. Nevertheless their assessment of the chance of success reflects an optimism that the present author cannot share.
