The OO point of view is just another mathematics.  This idea that
there is *one* mathematical point of view is just a holdover from the
way you were taught in school i.e. by authoritarians with something to
prove.

But per my http://www.4dsolutions.net/ocn/oopalgebra.html with
embedded rotated by quaternions XYZ cube (yes, wrote it myself --
better programmer than Arthur, duh), that's going to change.

What you thought mathematics was, based on what your teachers taught
you, is not the obstacle you might have supposed.
