have been discovered, such as gravity with F=GNmM=r2 and Coulomb’s law with F=
KqQ=r2, etc. In quantum theory there is an analogous structure. The Schrödinger equation, H =
i@ =@t, is like F=ma. It holds for any Hamiltonian." And so on, and so forth." src="/images/1px.png" data-src="https://pbs.twimg.com/media/DpbVlsEWwAIfOVn.jpg">
