One variety of this system with discrete states is named for Doubochinski.
One variety of this system with discrete states is named for Doubochinski. Kater devised a reversible one of these that can accurately measure the force of gravity and the differential equation that governs these objects can be solved symbolically with the approximation that(*) sin theta equals theta. Foucault used one of these to illustrate the rotation of the Earth. The double type of this object exhibits chaos. For 10 points, name this system that exhibits simple harmonic motion, made up of a bob on a string.
