WebJun 28, 2024 · As mentioned in chapter 15.4.4, the Hamilton-Jacobi theory is a formalism of classical mechanics that allows the motion of a particle to be represented by a wave. That is, the wavefronts are surfaces of constant action S, and the particle momenta are normal to these constant-action surfaces, that is, p = ∇S. Webdimensions in the obvious way. Cartesian coordinates have no preferential directions, so we expect the three-dimensional replacement: p ! ~ i r (18.1) applied to the Hamiltonian.
