Video title is How Maxwell's Equations Were Discovered, HN's regex thingy changed it to Maxwell's Equations Were Discovered. (My brain's regex changed it back :)

Only because it made to the HN front page.

A lot of stilted dialog first. Fine, fine, fine, I get it. Not everyone is a natural presenter.

Then I got to

> How copper and metal plates were combined

and I stopped.

"metal plates"? Copper's not a metal? Some details would be helpful. Zinc maybe?

The original title is much better How Maxwell's Equations Were Discovered. As it is now Maxwell's Equations Were Discovered it sounds like they were just discovered or someone rediscovered the equations.

If you like this make sure you watch:

which explains that magnetism is just an emergent property when you start from Coulomb's law and relativity.

I can imagine the world where this post gets more visibility through a funny regex error than actual equations :)

Interesting, I need to look into Maxwell's original formulation with the vortices. You can write electrodynamics in terms of small spinning elements: https://forwardscattering.org/page/Intuitive%20Quantum%20Ele...

if you aren't afraid of difficult math breaking your brain, I highly recommend this youtube channel "PhysicsExplained" (sorry I forget his actual name but he is brilliant)

he has a recent two-parter on Maxwell and electro-magnetism that are EXCELLENT

* part 2 https://www.youtube.com/watch?v=wt1KJtD4Qh8

but I am not kidding about the math, he starts off slow and gentle and hooks you in, but sometimes after 10 minutes in my brain is screaming and cannot keep up
