= Hamiltonian
{c}
{synonym}

Equivalent to <Lagrangian mechanics> but formulated in a different way.

Motivation: <Lagrangian vs Hamiltonian>.

TODO understand original historical motivation, https://www.youtube.com/watch?v=SZXHoWwBcDc says it is from <optics>.

Intuitively, the <Hamiltonian> is the total energy of the system in terms of arbitrary parameters, a bit like <Lagrangian mechanics>.
