e = mc^2 is the rubik's cube of equations, so this begs the question: what is the rubik's cube of ai? how can ai disrupt the field of using a rubik's cube to feel smart?

but isn’t part of the point of it that multipling values of the imaginary part will cycle back and forward?? like it’s not just a drop in replacement for x,y coords right? it’s used in engineering equations for particular use cases? what are those use cases??

look either you accept complex numbers or you stick with real numbers and accept that sometimes you'll solve reasonably simple equations and the result will be "gently caress if i know" because the result doesn't exist as part of real numbers. and you end up with a shitload of special cases for everything so on top of being able to do less it also sucks more also yeah there's some engineering stuff, signal processing stuff, quantum mechanics, and a whole bunch of other stuff. all the stuff. just so much stuff i mean schrodinger's equation has an "i" right there in it. wave functions that don't have a complex part will always have zero net momentum (iirc; it's been a while) pretty much the moment you have anything periodic it's just easier to represent with complex numbers

it kind of has its own structure though. the initial inspiration is definitely from practical examples, but then you get some big brain nerd that manages to tie together a bunch of things that look different at first, then extract some abstraction from that, and subsequent generations of nerds do the same thing, and eventually you get some really abstract stuff. then the math nerds start telling you that, actually, the stuff you call math is really just one possible system of mathematics you can build by choosing whatever axioms you want as a starting point and then seeing where that leads. then they start talking about groups and rings and fields and smooth, sensual manifolds, and then they'll try to convince you that it's critical that you be able to make an infinitely big pile of shoes by taking a shoe from other infinite piles of shoes or some equally insane thing and at that point you should probably just shove them into a locker

I certainly didn’t mean proof in a proper sense, I just meant in a more colloquial way, I would guess that to most people the complex plane is not intuitive in any way, and if you were to make the argument to a layman that it’s legit, it would boil down to “it’s legit because it works”. but i don’t really know enough about maths to make statements that don’t immediately bring up my misunderstandings lol

i wouldn't know how to distinguish between those two senses of proof either tbh. imo the gap between what is intuitive and what is useful really interesting, a lot of the results would have been called "magic" until we were actually able to do them, then they become science/physics/engineering/whatever

complex numbers are indeed in that category where they seem entirely random to everyone when first introduced, but then seem impossibly elegant in actual use.

once saw a video about the mandelbrot set but this one followed some of the recursive functions around and showed how some kinda jumped around in a box backwards and forwards and how some would be stable and more or less fall into a loop while others would spin out to infinity and I’ve had concept in my head before but this was the first time I really got what the mandelbrot set was doing stillll fuckin hate fractals but the complex plane is the mf poo poo
