Imaginary numbers are merely a poorly named mathematical construct used to reconcile the empirically observable phenomena of nature (e.g., summations of waves). They’re the means by which we achieve mathematical closure under exponentiation. You could call them whatever the F you want, so long as they could be used to represent vectors in the complex plane.
What reason do you have to believe in anything outside of material nature?
Up to the introduction of quantum mechanics imaginary numbers where only ever a theoretical tool and any calculation in electromagnetism, mechanics or even relativity can be done without them.
Also, any measurement you can make will always result in real numbers because there is no logical interpretation for imaginary measurements (a speed of 2+i m/s doesnt really make sense)
I said that any calculation in electrodynamics CAN be done without imaginary numbers, I never said that it would be the most common or convenient way of doing things.
If you use a different form of solution to maxwells equations, electrical impedance can totally be expressed as just another real property. Fourier transform also is not necessary to solve maxwells equations or any other physical systems. It just might make it significantly easier and more convenient.
Obviously imaginary numbers existed and where used way before quantum mechanics was a thing but they werent technically necessary in physics because they never appeared in the equations of fundamental theories (Maxwells equations, general relativity, newtonian mechanics)
I was just trying to make an argument that imaginary numbers were technically not necessary and thus it makes historical sense that they werent seen as something ‘real’. Im not trying to get people to stop using them ;)
Well, in AC circuits, having √3̅+√-̅1̅ A of current makes as much sense as having 2 amps with a 30° phase shift. It’s just easier notation for calculations - Cartesian coordinates for what would otherwise be polar.

It’s called a joke
Idiotic joke
It’s fucking mindless.
I bet you’re a blast at parties.
You’re fun!

Bro, are you not aware of the Fourier transform?!? Electrical impedance? Wtf???

Yes, and one CAN integrate by taking paper cuttings and dispense entirely with the idea of infinity.

Eh, this is not worth your time or mine to argue about. Let’s move on. Also, I take your point.
Imaginary numbers are indeed poorly named. They are not much more imaginary than members of ℝ.
It’s all fine… except for the part where reality has a √-1 component.

Yeah but quantum mechanics is just magic.
