How Electricity Actually Works


In November of last year I posted a Vertasium YT vid titled "The Big Misconception About Electricity".  Well it caused quite a stir and like an arachnid had many legs many of which attempted to draw A'gonrs into the poison fangs!

Well, here is the follow-up to that original vid which caused quite a stir in the "intellectual" community as well.

Vertasium "How Electricity Actually Works".

 

This does have implications for our audio cabling...

Einstein, like all big brains was confident perhaps to the point of arrogance (at times). However, he was also humble enough to admit he was wrong and did that when he was proven wrong.

When Einstein submitted a paper arguing that gravitational waves don't exist to Physical Review, the journal’s editor sent it back to for revisions. Outraged, Einstein withdrew it. By the time he submitted it to another journal, he had corrected his mistake. The revised paper argued that gravitational waves do, in fact, exist.

Almost every "great" physicist and engineer I have worked with will argue to the death that they are right. When you are in their field, they are not humble. However, what separates them from the not great ones is while they are arguing to the death, there is a little voice in their head going "maybe I am wrong". Arguing to the death is part of their process, even if unconsciously, for testing and refining their ideas. The not great ones don't have that voice. Their arguments become emotional, perhaps personal, and they won't go back and look for errors and test their hypothesis, but will look for reasons they are right. Even when it becomes obvious, even to them, that they are wrong, they look for ways to make it seem like something extraneous was responsible for their failing.

@deludedaudiophile -

     Thank you for establishing the point I made, in an earlier post, regarding not always believing oneself to be THE POPE!

                                                                  As I posted::

Feynman was and will remain, my favorite lecturer (yeah: I’m that old).

He mentioned often (and: I took to heart) his favorite Rule of Life: "Never stop learning!"

For all his genius, he never grew overly confident in his beliefs. The perfect obverse to the Dunning-Kruger sufferer.

ie: “I can live with doubt and uncertainty and not knowing. I think it is much more interesting to live not knowing than to have answers that might be wrong.”

and: “I have approximate answers, and possible beliefs, and different degrees of certainty about different things, but I’m not absolutely sure of anything.”

Tesla is probably my favorite innovator, who (despite the incessant, projectile vomit, from his day’s naysayers), took the World, kicking and screaming, into the 20th century, with his inventions.

@builder3 I'd say that there are a lot of affluent people here...seems there is a low positive correlation between detailed technical knowledge and fiscal success.

Just as there's an obvious and direct correlation between how impressed you are with yourself and how much of a complete jack**s you are

When I don't understand something and my head starts spinning I just remind myself the earth is the center of the universe and not to wander over the edge.

Some day we will understand electricity, but today is not that day.
