    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.

        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.

          That’s BS notation. If you want Cartesian, just use 3i+1j, no need for some impossible √-1 that you then redefine some operations for, just so it becomes orthogonal to R.

            The nice thing about 𝑖 = √-̅1̅ is that you don’t need to redefine any operations for it, ℐ𝓂 is “automatically” orthogonal to ℛℯ.

            You might want to look up geometric algebra for a better geometric interpretation of complex numbers than the complex plane with a “real” and “imaginary” axis
