```"That this subject [imaginary numbers] has hitherto been surrounded by
mysterious obscurity, is to be attributed largely to an ill adapted
notation. If, for example, +1, -1, and the square root of -1 had been called
direct, inverse and lateral units, instead of positive, negative and
imaginary (or even impossible), such an obscurity would have been out of the
question. " -Gauss
