This reminds me of a strange story
I've learned long time ago.
A dynamical system which passes
through a succession of states,
at constant time intervals, is
a clock. Clocks measure times,
and, coupled with other systems,
can also measure the duration
of a physical process. Clocks can also
be used to control the duration
of a process, or the evolution of a
physical system. In this case if a clock
has a good time resolution, there is
some energy exchange between the
clock and the controlled process,
that is the evolution of the physical
system under control. Both the evolution
of the physical system and the clock
are then perturbed, because when you
include the clock mechanism in the Hamiltonian
describing the quantum system to be observed,
or to be controlled, you get this perturbation.
If then a clock is too precise, a sort of
quantum Zeno effect occurs - the evolution
of the physical system under control may be
even halted.
