spent years reading/drawing schematics. simplified bridge rectifier circuit used everywhere. like your phone charger. magically keeps face glued to phone

looks at schematic

FULL BRIDGE RECTIFIAH!!

it gender transitions the AC to DC

And in this specific application (simple resistor as a load) you could even save all the diodes and generate even more heat in the resistor alone instead of also „heating“ the diodes. *

This my most favorite circuit. It’s a very simple and elegant solution doing its job in silence without getting the kudos it deserves.

  • I know RL is just a simple generalization for a load.

Lightning would be wild magic

Makes sense. Could be harnessed to do something probably but incredibly dangerous to do so.

Said it before and I'll say it again: just because you understand the magic doesn't make it any less magical. A wizard may know the ins and outs of their spells, but they're still spells. Our entire universal is fucking magical, we just happen to have a decent understanding of why (some) of it functions the way it does. Jiggle a quark here and another may jiggle the same way somewhere in the vicinity of Betelgeuse, that's fucking wild and magical and incredible, and just because we have some level of understanding behind the mechanics doesn't make it not magic. It just makes it a hard magic system.

Squint at this (from this wiki page https://en.wikipedia.org/wiki/List_of_demons_in_the_Ars_Goetia) and these might be either ancient sigils or electronic symbols*.

EDIT: Fixed a typo

We always joked it was black magic but its literally on the name.

An actual textbook cover. I mean... An ancient grimoire of the dark arts

Edit: I almost forgot about the sequel

It's chemicals that make signals jump between neurons in your head. Electricity acts entirely withing single neurons.

Also, that's a control spell, not a summoning one.

Paraphrasing Arthur C. Clarke: Any technology is indistinguishable from magic, to the sufficiently ignorant.

[–] bss03@infosec.pub 13 points 1 week ago (1 children)

Clarke's Maxim: Any sufficiently advanced technology is indistinguishable from magic.

Corollary / Contrapositive: Any technology distinguishable from magic is insufficiently advanced.

That diagram is just heat with extra steps.

[–] piranhaconda@mander.xyz 10 points 1 week ago* (last edited 1 week ago)

I mean, yea. The people designing the AC to DC power supplies often don't care what you use them for, why would they bother putting schematics for a real load on their diagram?

You think a rectified transformer is a magic circle? Get a load of the Smith Chart

In any case, it's powered with electricity.

Um akshually, that's a rectification circle.

The mages of Electrical Engineering reseach the tools and formulars to control the magic. The mages of Hardware Engineering develop under great effort the sigils and rituals of how the rocks must be processed. The Warlocks of the CPU use the near infinit possibilities of algorithms and the power of the evolved rocks to create worlds nobody could ever have imagined (in exchange for the ability to go outside).

Yeah but it's too realistic, I want something convenient! Let me read one book and gain the power to create floating ice! Not read like 5 giant books and stufy for years so that I can create a microwave 😔

No shade to microwaves, one of my favorite magic items

When we figure out how to manipulate elctro-weak at scale, it will be magic.

Electro-mag is pretty crazy already, I agree. The ICP can't even figure out how they work.

For me, the weirdest thing is that when a charged particle moves through a magnetic field, it experiences a force perpendicular to the direction of motion; this results in the particle tracing out a curved path through the field. Like ... what the actual fuck? Why in hell would the universe be this way?

I'd expand it to electromagnetic fields or something instead of just electricity.

[–] Beacon@fedia.io 10 points 1 week ago (2 children)

Hm, the stuff in wires is electrical current, but the stuff in nerves is static electricity based on an electrochemical gradient. Yeah i guess that all falls under the heading of electricity. No quibbles, carry on.

But the summoning circle doesn't do anything on its own, you have to build it and then go and find the electricity to plug into it yourself

[–] pennomi@lemmy.world 32 points 1 week ago

Pretty sure that’s how it works in a lot of fiction. You draw the circle then activate it by putting in mana.

[–] officermike@lemmy.world 26 points 1 week ago (1 children)

Many summoning circles require a sacrifice, and this one is no different. This one requires a sacrifice of AC to summon DC.

RF engineer here, living the life of magic in the air and space!

[–] Grandwolf319@sh.itjust.works 9 points 1 week ago (2 children)

While I fully agree, I thought the distinction was unbreakable rules.

The laws of physics can’t be broken, even, under any circumstances, everywhere, at any time.

Whereas magic is more like there is an exception to every rule kind of deal. It’s far more like software, as in it’s mostly fully logically consistent except for random spots where devs took some shortcuts to make life easier.

[–] mic_check_one_two@lemmy.dbzer0.com 18 points 1 week ago (2 children)

I think the “exception to every rule” part is really dependent on which type of magic the writer is using. Many writers do establish hard rules for their magic. In those cases, it’s less “magic is the exception” and more “magic is engrained into the laws of physics.”

Well, there's actually a sourcebook for Arcane Engineering
