A researcher in dynamical stability who, with <Mark Levi>, analyzed a particle in a <rotating saddle trap>. Rapid rotation can stabilize motion even though the stationary saddle is unstable. Their calculation also finds a slow <precession>, represented in the averaged equations by a Coriolis-like force in the laboratory frame. This links dynamic stabilization to the behavior of a <Foucault pendulum> and distinguishes a rotating potential from a particle constrained to a rotating surface.<Rotating saddle trap as Foucault's pendulum by Oleg N. Kirillov and Mark Levi>[Abstract and introduction: stabilization, laboratory-frame precession and distinction between mechanical models]{ref}
