Summary: If r parameters controlling a complete system are arbitrarily under our control, then
we can, by controlling the parameters, force an arbitrarily selected set of r variables to behave as we chose. The detailed control can, so to speak, be transmitted
through the many other variables without any loss of control! Input control possible Parameter degrees of freedom
Summary: Studying a system via one variable. Continuity in discrete sets Epistemology : The whole system can be studied if one variable is observable; in particular, all
the canonical equations can be deduced 5054.
