The Hamiltonian Formalism We’ll now move onto the next level in the formalism of classical mechanics, due initially to Hamilton around 1830. While we won’t use Hamilton’s approach to solve any further complicated problems, we will use it to reveal much more of the structure underlying classical dynamics.
