Can we have a serious discussion about resonance?

I think that nearly everyone with any background or even sense about physics and technology has a gut or intuitive sense of resonance.

Certainly, even the layman has an intuitive feel for the subject, in the sense of something "resonating" - echos; a string "spontaneously" vibrating to end up producing a note; the cup of water in the opening scene of one of the Jurassic Park movies; sub- and ultra- sonic vibrations that, for whatever reason, end up creating a harmonic that then manifests itself in some other perceivable phenomena like crystal flying apart in a thousand pieces.

At the heart of this subject seems to be the more readily "graspable" phenomenon of vibrations, and by extension, more abstractly, wave and particle physics. Specifically, oscillation frequency, which has practical implications in things as divergent as repeater functioning and "sound quality" to the wind buffeting in the cabin when the second row window is open in your Navigator SUV to the sturdiness of the boat frame as it "skips" across the wave tops.

Based upon my elementary school level understanding of physics, all things in nature have a natural vibrating frequency, even down to the sub-atomic levels.

Specifically in regards to "resonance" as a phenomenon, I recall (forgive me, it has been decades) that

a. all things have a natural frequency, since all things are made of molecules, themselves made of atoms, themselves made of sub-atomic particles, and at the most fundamental, sub-atomic levels, there are natural frequencies of vibration, which can be cumulative, or cross cancelling, on up the complexity chain.

b. the introduction, naturally or artificially, of another frequency of oscillation which interacts with the natural frequency of the object being studied for resonance.

c. the interaction of these two vibrations, which either reinforce or mitigate each other, results in the various effects and benefits/harmful results of resonance (bridges falling down, pleasant or hurtful sounds, balances and hairsprings that achieve resonance and therefore have even more rate stability, etc Is it possible even gyroscopic effects have their basis in resonance?)

As Tesla and other "great" scientists have shown, these natural frequencies can be harnessed and manipulated to create broadcast media like radio and television; MRI (Magnetic Resonance Imaging) machines; even orgasms in human and other living organic beings.

So what does this have to do with horology and chronometry?

What is it about the Janvier resonance clocks? Journe's Resonance wristwatch? Haldimann's new double resonance tourbillon? What is the theory, and what are the facts?

Anyone?
