"Veritasium" (YT) - "The Big Misconception About Electricity" ?

A recent newspaper comic strip:

I was worried that might get a bite or 3. I wasn't being (all that) serious, but from my POV "lateral" numbers in engineering especially, are the more needlessly complex concept, and less direct one. The fact some people find it so absurd and offensive highlights just how much of a buy-in one's training can get. I think I'd rather be without it.

I don't find imaginary numbers all that "icky" either - more "interesting".

This is because they proved, after getting their degree, that they understand what they will "criticize".

If that were true, scientists weren't be fiercely trying to test all the current theories to the limit in this very moment.

You seem to need it now.

A rigorous definition of real numbers is the product of the 19th century, i.e. later than the acceptance of the existence of the imaginary numbers.

Since it was Descartes himself in the 17th century who gave that name to real numbers to distinguish them from the "imaginary" ones, before the discovery of the "imaginary" number no one knew that there was such thing as a "real" number, and then it took quite a while for people to figure out how to define a real number.

I thought that you hated math. But I'm starting to think that it is math that hates you.

FYI, Derek has done his follow up video, it's on his Patreon account for early access so I won't link to it here.
It's very good and adds lots of new detailing while admitting the lumped circuit model is the easy and obvious way to analyse it.
Although no mention of quantum electrodynamics, but I can understand how that might derail the video.

Having been dealing with Derek on this over the last 4 months, including an almost hour long video chat, I can attest to the great pains he has gone to to try and clear this up. And how his question was not a troll and he genuinely wants people to learn and was really surprised at the reaction it got. He was originally going to do a response video before xmas, but got the heebie jeebies after our chat and did a whole bunch more work, most of which you never see in the video. He was considering scrapping the video at one point fearing that he wouldn't get it perfect enough to please everyone, but I think he did a really good balanced response.

You'll see his video within a day or two I'm sure, or go join his Patreon now to see it.

I haven't seen the video yet. But the lumped circuit model as an easy and obvious way to analyze it was never the subject of his video or this thread. What we discussed was where exactly does energy flow, in the wires or in the space between them.

The lumped model is an analogy which, although it helps, as any analogy, imposes limitations and even unnecessary complications for many circumstances, which the savvy engineer must be aware of.

I still cringe that a guy like Derek has to apologize for revealing to the common people something that engineers ignored.

Reminded me of the myth of Prometheus who dared to teach humans how to make fire, angering Zeus, who bound him to a rock to have his liver consumed daily by an eagle.

I'm looking forward to seeing his video and I hope it helps to interrupt this trend, among some so called engineering "influencers" at least, of attacking the ones who manage to bring profound concepts to the masses and dissipate misconceptions even among engineers.
