How about this for a thought. An EM wave has two components - an electric field and at 90 deg to that a mag field. Could it be these two components somehow have an oscillatory nature? Could this be linked to an electron wave function?
Isn't the answer to that question built into the description of an EM wave?
"Electromagnetic waves have two components: an oscillating electric field and a perpendicular, comoving magnetic field which oscillates at the same frequency, but with a phase shifted by 90°."
I don't see a connection. The wave function describes the position of an electron, but it is not electrons that are oscillating in an EM wave.
You get into trouble with Quantum Mechanics the minute you try to interpret it, or even worse, philosophise about it! Just follow the equations! 🤣

An EM wave is not viewed as oscillatory in the normal sense (please correct me if my understanding is incorrect). IIUC it is 'driven' by the emitting energy source and the frequency is set by the source - there isn't a 'natural' vacuum resonant frequency that I am aware of. My question is this: Is energy stored in either the E wave or the M wave and transferred between the two in the manner I described in my earlier post leading to the observed EM wave with the two fields at 90 degrees?
Fair enough on the point re electrons - in an EM wave we are talking photons. However, electrons do emit photons when excited, so that's where the link exists if there is one. You obviously can't know the exact position of an electron because in doing so you will have to impart energy to it (a photon) and that will move it.

You got me thinking there, Bonsai!
The point of similarity between Maxwell's Equations (which is about electromagnetism, and not a quantum idea, i.e. there is no h(bar) explicitly involved) and Schrodinger's Wave Mechanics (which is about matter waves and h(bar) is crucial, it is the quantum...) is they both use a wave equation.
Wave equations work rather nicely with exponential functions:
Anyway, lot of handwaving here. What does a quantum point particle like an electron look like as a wave? This is Scrodinger's wave idea, rather than Heisenberg's matrix interpretation:
https://en.wikipedia.org/wiki/Mathematical_formulation_of_quantum_mechanics
You add a sum of kinetic and potential energy Hamiltonian (H = T+V) to the workings:
Differentiation becomes an operator. Anyway, with a Hamiltonian and the right boundary conditions, some simple but powerful solutions exist. Here he quantum harmonic oscillator: You can do this fairly rapidly on half a page:
Quantum Mechanics in one post! 😎
Of course, it gets worse... but lovely maths that also applies to loudspeakers and information theory and Fourier and Laplace transform.... 🙂

Geoff, at a Forum, which is entirely different from Social Media, the general rule is to reply to the previous post.
You seem to be establishing a reputation as a "Loose Cannon".
And I quote:

My understanding of Digital Signal Processing is the signal is perfectly preserved by error correcting codes unless Gross errors:

And I have a moderate competence in Analog and Digital Signal processing:
https://en.wikipedia.org/wiki/Z-transform
AFAIK, it works:
So why do I need green pens and pads to stick onto my CD player. Perhaps you are mistaken? And TBH, we have all made mistakes... so don't be too hard on yourself. Just be a better Engineer.
Stay Classy, San Diego. 🤣

Well excuse me for breathing. I don’t use social media. Reed Solomon is OK but doesn’t correct all errors. Same for laser servo feedback system, it can’t keep up, the scale of the data spiral is too small, nanoscale. The disc is out of round So it tends to flop around in there whilst spinning. They did the best they could in the time allowed. Looks like you’re another person who bought into the whole Perfect Sound Forever nonsense. That was what, 50 years ago? Cut me some slack, Jack. Thanks for sharing Michael Green’s screed, poor guy, much laughs. 😀
I guess personal attacks are ok in your book, eh? 😲 Typical pseudo skeptic kid’s stuff.

Ok. Superstitious people are generally successfull people. Idea behind superstition is be successful in whatever you do. It's pretty greedy if you ask me tho.
Unless we can predict future perfectly to the T. Superstition will exist. Even flourish.
That's why I say to disprove God. We need to became God. Because where the science ends God start. There is no other option.

I have not come across any suggestion that energy is transferred between the oscillating electric field and the oscillating magnetic field.
The stock explanation is that an oscillating charged particle at the source will cause the electric field surrounding it to oscillate as well.
The oscillating electric field, in turn, causes an oscillating magnetic field, as predicted by Maxwell’s equations.
A self-sustaining electromagnetic wave can carry energy through empty space as the electric field component and magnetic field component each continually change and each perpetuate the other.
As an apparent correction to an earlier statement, the oscillating electric field and an oscillating magnetic field oscillate perpendicularly to and in phase with one another as shown in the attached gif.
That's all I can offer with the help of some confirmatory googling - without atttempting to delve into mathematics that I would be unable to follow!

Thanks for your additional words of explanation, but I think it's best we keep certain references out of our discussions.
I don't wish to cut our resident pseudoscientist too much slack, but he did respond to Steve's reference (and link) to Reed Solomon Error Correction which was directly above his post.
This thread is not audio related.
I suggest you take your "Advanced Audio Concepts" elsewhere.
I was addressing Steve. He brought up audio stuff, not me. you get your nose out of joint rather quickly. And frequently. I was cruising along on the EM wave discussion. I can Google as well as you can.

Where/when science ends, why just not settle with that and declare (temporary...) ignorance - instead of guessing/belief?

You brought up the topic of your "intelligent chips" in post #2,672, and that, or similar, is what Steve referred to in his mention of "pads to stick onto my CD player".
You can't pull the wool over everyone's eyes!
Well, theoretically it's not hard.
Assume mass has momentum... then even though the absolute aggregate of mass will be much greater than the effective aggregate of mass as momentum can cancel other momentums...
Somehow, though, I think the current models are reaching an Occam's Razor event horizon.
