You don't get it. There is a phenomenon that your dumbed-down understanding can't explain.
-- Here, take this theory, it explains it in clear terms what is going on.
-- Oh no, I'm an engineer, I cannot see the world except through my dumbed-down understanding. In fact, I'm going to declare that this phenomenon doesn't exist and who says that it does is wrong.
Give me break.
This kind of mindset is stupid. Especially in the case of engineers who are thought this bleep in their respective degrees.

I guess I asked for that, so I will take it on the back / shoulder (where a punch would land if I were in the process of running away, but not motivated or focussed enough). You have a point and I should have sucked it up and done the math. When given a choice between "veggie maths" and the class taken by Roy Kerr, I should have stuck with the latter (I think I did some), and various other mild or moderate regrets associated with my academic "choices" (but it really was a one size fits all conveyor belt, except for aforementioned veggie maths).
But you know what I'm going to say:
"You don't get it. There is a phenomenon that your dumbed-down understanding can't explain."
QFT. Whatever comes next.

Maxwell's equations and the Poynting theorem explain the phenomenon perfectly. But I have no problem with QFT. Maxwell's equations are just QFT for when the Plank constant is made zero. Or, if you prefer, when we have a large number interactions between particles. Since we are dealing with a macroscopic phenomenon, and not the interaction of a few particles, h = 0 is a good enough approximation.

So are the others who said he is wrong. All of them have talked out of their butts. Lots of views. All opinion. No facts.

Like your post right there?

Did I miss the post where you used those to accurately predict the behavior the circuit in question before experiments were done? If I did could you link it for me or give me the reply#? I apologize in advance if you did post such an analysis. And I don't mean the trivial answer of 1m/c that despite allegations of engineers not understanding light speed due to dumbness, very few people here actually missed.

I know. That's why I said "like radio, and QFT" (I wrote that before all this QFT stuff came up over the last few days). QED essentially derives from Maxwell's equations, and QFT generalises on that, extremely effectively.
Yet, like it or not, QFT has provided a 'worldview' which assists in 'debunking' (intentionally being loose with that wording) Poynting's vector as a source of truth for power flow at DC, a situation which is not far off being untestestable. It would require the experimental capabilities of Henry Cavendish's Earth density determination squared.
