It's an electrostatic field...

Of course.  Electrostatic fields have been known for almost 200 years - Oersted's work  We know what they are and how they work for a long time.  We don't understand why they work.  We really don't understand why the work after the elements are separated for days when we can't quantify the individual charges in separation only in proximity.

It is like you "love" your (substitute almost anything) sound-system.
Can you measure your "love" for your sound system or the joy you get listening to you tunes?
May be not ...

Yes.  And mathmatically describable.

The part that the teacher is ending with, is the electrostatic field a wave, particle or virtual particle?  Since it can happen in a vacuum, there are no particles, so it appears to be a wave.  It can also be described as a disturbance in an electron field as a photon.   He is alluding to the underlying process of the electric field.   Then you get into quantum physics.

A cool way to get young minds thinking about the physics of electric fields and energy storage.

Another fun thing to think about is since a capacitor does not totally contain the electromagnetic field between it's plates and there is leakage, how does that interact with it's local environment and cause changes to the circuit and sound?  Same goes for cables in the environment. 

Some of the new circuit modeling systems let you take the component E-M fields into account and help with layout.  Would be interesting to visualize that capability.

I've seen it best theorized as corresponding displacements in the energy states of electrons in opposition that sums to zero in separation.  Just a theory so far, but interesting to ponder when one has a mind for why as well as how.

The way the article relates to audio is summed up in the end.

There are tons of things that we know make clear and repeatable audible differences. Yet, we often have a hard time measuring those things. I can think of lots of examples.

There you go again

I can: smiles, enjoyment and relaxation X [foot/nuthin] = love for music

Good point.   

Off to the shop.

Taking a bit of tangent ... but something very similar ...

The energy (feeling) created during a meditation session does not get destroyed ... actually you can re-live it / tap into it ... by going back to that space in your mind ... (by thinking, feeling, visualizing or imagining)

That is why when a group continues to meet for a period of time - people experience the increase in intensity of that energy in that group ... It is based on my and many people's experience ...

It goes back to what we know - energy cannot be destroyed, of course it is beyond that ... we experience it ... sometimes we can and sometimes we cannot explain it or explain it incompletely ...

  Cannot be, snake oil, lies, nonsense. HA !!! Love it. A very interesting experiment which proves we still have a lot to learn.

Exactly.

Well the teacher did a poor job of describing the experiment but maybe he thought that his students were more knowledgeable and smarter than the magazine article author.  It's true that the origins of this phenomenon are not entirely understood.  Maybe a little reading of a book like "The Art of Electronics" would have given the author a better understanding of how real world capacitors work.
