Tolliver's counterexample, which he calls the pendulum case, goes like this: suppose a physics student has learned that from the period of a pendulum (i.e., the time it takes to complete a swing) one can calculate its length and vice versa.
The pendulum is rapidly swinging back to the old condition of things.
