Maxwell's Equations Were Discovered [video]
- Ono-Sendai 4mo agoInteresting, 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%20Electrodynamics https://forwardscattering.org/page/Intuitive%20Quantum%20Ele...
- amelius 4mo agoIf you like this make sure you watch: https://www.youtube.com/watch?v=sDlZ-aY9GN4 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.
- Ono-Sendai 4mo agoNah, special relativity is a consequence of magnetism.
- selimthegrim 4mo agoThat's not how Purcell's textbook put it.
- Ono-Sendai 4mo agook? well, textbooks can be wrong or misguided.
- selimthegrim 4mo agoUm...
- amelius 3mo agoYou're reading something that isn't there.
- andai 4mo agoVideo 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 :)
- amelius 4mo agoIsn't it about time HN replaced the regex by AI?
- wolfi1 4mo agooh oh
- amelius 4mo ago:)
- dvh 4mo agoRemoving how is stupid. If the "extraneous" how is there, you can still understand it, but when the necessary how is removed, it doesn't make sense or it changes meaning. When I read the title I thought someone is trying to lower the weight of Maxwell's contribution by suggesting he merely discovered them, not "invented" them.
- meltyness 4mo agoI want an AMA on whoever had an army of upvoter bots on early Reddit such that every front page post would have a dictionary typo.

- tim333 3mo agoDoes anyone know why the regex is there? I find it hard to see how english communication is improved by removing random words.
- AlexeyBrin 4mo agoThe 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.
- bee_rider 4mo agoI expected a philosophical discussion as to whether scientific models are discovered or invented.
- bpavuk 4mo agoI can imagine the world where this post gets more visibility through a funny regex error than actual equations :)
- ck2 4mo agoif 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 1 https://www.youtube.com/watch?v=YqxrlunKCaU https://www.youtube.com/watch?v=YqxrlunKCaU * part 2 https://www.youtube.com/watch?v=wt1KJtD4Qh8 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
- kayo_20211030 4mo agoOnly 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?
- blovescoffee 4mo agoI guess I would read this as “copper” as a primary requirement / necessity and some other metal as a secondary requirement. Are you just being pedantic?
- DemocracyFTW2 3mo agoregarding your objection to 'metal'—technically that wasn't a 'dialog' but a 'monolog(ue)'.
- sonorous_sub 3mo agoThose 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.
