So is E the total energy of the system potential plus kinetic? Mirwin 05:32, 6 February 2007 (UTC)

Yes. In classical mechanics the Hamiltonian is the energy of a state. In QM we have states with well-defined energy (which fulfil Schrödinger's equation -e.g., the electronic levels of an atom, for the state of its electrons) and superpositions of those states (for which there's no possible value for E -note that E is a scalar and H an operator). This is an eigenvalue equation. --Jorge 05:44, 9 February 2007 (UTC)

- Hmm...I'm not sure if the original question has a yes or no answer...The Hamiltonian H is constructed from two operators, one of them corresponds to the potential, and the other is kinetic. E represents a set of values which are allowable energies in the system. --HappyCamper 02:44, 11 February 2007 (UTC)
