[EM] Resonance

[Michael Ossipoff]

Fobes says:

Such over-runs are a component of the concept of "resonance" in Physics.
  This over-extended "state" quickly lead to an ever-increasing push
back to center.

Incorrect.

Resonance, in physics, refers to a physical system's natural frequency
of oscillation. The frequency at which it would oscillate without any
outside influences.

As for the "ever increasing push back towards center": For small
displacements the restoring-force typically tends to be approximately
proportional to the displacement from the center (toward which the
restoring force acts). Motion under the influence of such a
restoring-force is called "simple harmonic motion. For instance,
clocks, whether with pendulum, balance wheel or quartz, are designed
for simple harmonic oscillation, because one of its results is an
oscillatory period that is independent of the amplitude.

Galileo is said to have observed that independence, in the swinging of
a chandelier

But "resonance" only refers to natural frequency.


Fobes continued:

 Yet, overall, the result is an oscillation that
averages out to be centered.
