Hi. Say we have found a hamiltonian ##H## for some system.
So I know that if ##\frac{\partial H }{\partial t} \neq 0## then obviously the energy of the system is not conserved.
But if ##\frac{\partial H }{\partial t} = 0##, is the energy always conserved? Or do we need to find that ##\frac{d H }{dt} = 0## to know for sure?
