Mar 15, 2020 at 13:49 comment added doublefelix I think the OP's question is pretty clear: how can an operator, like $-i\hbar \frac{\partial}{\partial x} $ depend on time? To anyone with the usual math background before QM, they are only used to functions depending on time. And an explicit example of an operator which depends on time is hard to find in the opening chapters of textbooks. So what's the issue with the question? @Qmechanic . I think this is a case where a bit of "putting yourself in the OP's shoes" makes it clear what sort of answer is needed.I don't have the time to write one today, but I don't see why thequestion is closed.
Mar 15, 2020 at 9:09 comment added Roger V. Sometimes they do explicitly depend on time - e.g., the electric field is often included via time-dependent vector potential.

Mar 15, 2020 at 8:07 comment added Charles Francis I think you may be confusing an observable operator on Hilbert space, e.g. $X$, with the result of the observation on a state. Typically (in the Schrodinger picture) the state is changing in time, but the operator is not.
