Anybody know why quantum mechanics uses the Hamiltonian instead of the Lagrangian? Do people just feel spiteful of Lagrange? My roommate is one of Lagrange's descendants, and he's threatening to be an hero, so a quick response would be helpful.
Thanks

the hamiltonian is derived from the lagrangian.

Lagrange was french. Nuff said.

True, but that doesn't explain why we would prefer a derived quantity over the original.

Hamiltonians are simpler. People teach the Lagrangian in particle theory and in grad-level quantum because it's more powerful.
