This is a very short update from a guy that likely goes under the name of Alen.
Now for years Alan has a very weird page hanging out there and he tries to describe the 3D complex numbers as they should be in his view…

Very very likely this is the approach Hmilton took for 12 to 15 years; it leads to all kinds of horrible difficulties, technical disasters and an end result useless to all people on the globe.

Now you must not jump to the conclusion that I hold this Alen person for some idiot. It is rumored that at any given time there are about 100 thousand professinal math workers out there and I do not mean high school teacher but people from the universities and stuff like that.

All these people cannot find higher dimensional complex number systems themselves either…
Ok, enough of the bla bla bla en prepare yourself to dive in the blurry and fuzzy mindset of how people thought 3D complex numbers must be (it is always with something squared that is minus one…):

N-DIMENSIONAL COMPLEX NUMBERS.
