Ch 2.7, Ch 7.4 The result that quantum expectation values obey classical equations of motion: $m\frac{d\langle\hat{x}\rangle}{dt} = \langle\hat{p}\rangle$ and $\frac{d\langle\hat{p}\rangle}{dt} = -\langle\nabla V\rangle$. This explains why classical mechanics emerges as a limiting case. *Common conf
