In Python, complex numbers are typed as follows: 3+4j. This kinda bugs me that they use "j" instead of the traditional "i", particularly because quaternions (4-dimensional complex numbers) use i, j, and k for the three "imaginary" directions, so this would cause some overlap. But then I got to thinking ... would using the "j" from a quaternary system be any different than using the "i"? Don't they each have the same properties relative to the real number line? I'm fairly certain they do, but my knowledge of quaternions comes almost exclusively from Youtube and Wikipedia, so I'd like to hear an actual expert's opinion.
