First the fact that I use a two dimensional model is obviously for illustration purposes only. Of course everyone knows that we live in a 3 D world and the sphere would take the place of the circle but 90 degrees would still be the pertinent angle. Your argument that it would be 360 degrees is either a bad attempt by you to belittle this thought or an apparent misunderstanding of the premise. The angle formed on an "x", "y" and "z" grid would be identical to a two dimensional "x" and "y" grid when we are dealing with the plotting of points. IT WOULD STILL BE 90 DEGREES !
You then move on to try to belittle the fact that I perceive these things in a different light. You attempt to mock this by using what you consider your special brand of humour, which I like Darius am beginning to find rather distasteful. If this is your best form of rebuttal I would prefer that in the future you keep them to yourself !
