🤔 This one seems to have sparked an interesting debate on electromagnetism. For spoilers, the best answer/refutation I've seen is

Since there seems to be dispute, it would be nice to see a real experiment, not just "my oversimplified models are more detailed than your oversimplified models, so I must be right".

I think if u nailed down specifics enough to do an actual experiment then the disagreements might melt away. I can't imagine a Michelson Morley style paradigm breaking experiment here
replied 1277d
Maybe. It just seems a bit silly to hit each other in the head with laws of nature, when mother nature may not have been informed of said laws or their generality.
replied 1277d
As I understand it there are many issues here, one being that some say individual electrons do not move very fast through wires at all. This may play heavily into it all.
replied 1277d
And even if they do travel at ~c, the claim that you got a big condensator initially, I dunno if this really is an "absolute truth". I got lots of such doubts.
replied 1277d
Anyway, I suppose an experiment can be scaled down considerably from the puzzle text, but still it can get very expensive because wires must be superconducting.
replied 1277d
I think the 1st guy seems to allude to the prospect of an experiment, so something might happen. Don't know about superconductors.
replied 1269d
Not superconductors, but real experiment

Atm I am not sure the superconduction demand makes much of a difference.
replied 1268d
nice. But i’m not sure about his omission of inductance. Seems like that’ll be in part 2 though.
replied 1268d
Just by reading this, not looking stuff up or rewatching vid, I don't really know what you are talking about here. But didn't he say that something like that will come in part 2?
replied 1268d
Yes. He didn’t mention inductance except to admit he didn’t mention it. He implied he would give fuller explanations in part 2.
replied 1268d
So what is your problem with him not (yet) talking properly about inductance? Do you see a problem with his experiment or arguments that this will address?
replied 1268d
Maybe it’s me who’s wrong. But current in 1 wire inducing opposite current in a parallel wire is well understood. To discuss the phenomenon yet not name it seems strange.
replied 1268d
Maybe a better experiment might have the switch and bulb on separate but parallel circuits. dunno.

I am but a humble layman in such matters and suspect you know more than me, but i still don't see how either model ultimately predicts a fundamentally different outcome.
replied 1277d
I may not be humble but I am definitely nothing more than a layman. Anyway, I thought there was some disagreement, but the first vid, some time since I watched it, remember few details
replied 1277d
I also suspect all involved know this and are playing the 'scientific controversy' angle for clicks.
