Could you observe the clock moving if you had no memory? For example,
could you describe an algorithm that detects movement without
resorting to keeping state in some variable?
I wonder why these states cannot include derivatives. If we model a dynamic system, like
a clock, in a computer, the model is often a set of differential equations. So the state
is not just static values but also the derivatives (rate-of-change) of those values. Then
the 'movement' is captured in the variables of the state.
