If you like this make sure you watch: https://www.youtube.com/watch?v=sDlZ-aY9GN4 which explains that magnetism is just an emergent property when you start from Coulomb's law and relativity.

Nah, special relativity is a consequence of magnetism.

You're reading something that isn't there.

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 :)

Isn't it about time HN replaced the regex by AI?

Does anyone know why the regex is there? I find it hard to see how english communication is improved by removing random words.

Those godawful ads on youtube though. I pay goog to suspend them, but I forgot to login on my phone and now I’ll be haunted the rest of today by the snippet of a mouth-breathing honey vendor who popped up on screen before I could scroll away.

It's to avoid headlines being extra attention grabby. It's an imperfect program, but it does alright.

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?

regarding your objection to 'metal'—technically that wasn't a 'dialog' but a 'monolog(ue)'.
