physics ≠ magic
(lemmy.ca)
Not pictured lightning making the rocks think
NO THEY'RE NOT GOLEMS SHUT UP
Lifeless? Soulless? Speak and move only when infused with lifeblood or arcane essence?
Sure quacks like a golem
Is the last pic the criticality blue glow from reactors?
Ah, it’s a photo of a mercury arc rectifier (which is more electrical engineering, maybe?), not, Cherenkov radiation.
"Mercury" and "arc" on the same sentence do really, really not make one imagine something that perfectly fine to use or be around in operation.
Nah it’s a glass something that has to do with electricity but I forgot what
Just plain old blue electrical arcs.
On the other hand, Cherenkov radiatiation is only indirectly related to criticality. It comes from any particle moving through a medium, generally water, faster than light travels through that medium. A luminous sonic boom of sorts! It's associated with criticality because those are the contexts where it happens often enough to actually be visible.
That's exactly what a ~~magician~~ physicist would say.
the blue what the fuck looks cool
Mercury-based diodes both look way cooler and are way less spooky than garden variety semicondictor diodes.
Anything smartphones do seems more appropriate. That stuff is hardly mentioned here.
I understand smartphones. They are relatively simple devices.
Apart from GPS and 5G communications which are pure black magic.
And magnets: magic
Simple...? Just understanding how transistors can be combined to generate a picture on a screen is crazy complex.
Magnetic fields are a big part of smartphones in various, different uses. GPS is low tech compared to how the CPU is made.
