I'm saying that there would be no such thing as objects, movement, space, or rotation in a comp universe. You can prove this by understanding that there are no objects or spaces actually moving around in the chips of your computer. Everything that you want to do with arithmetic can be done with numbers alone, no points, spaces, lines, forms, or objects are ever needed, nor could they add anything to the functionality.

This is my point, we have visual intuition because we have visual sense as a method of participating in a universe of sense. It would be meaningless in a universe of arithmetic. > Look at i, it sits one unit above the real horizontal axis so draw a line > from the real numbers to i, so if you multiply i by i (i^2) it rotates to > become -1, multiply it by i again(i^3) and it becomes -i, multiply it by i > again (i^4) and it becomes 1, multiply it by i again (i^5) and you've > rotated it a complete 360 degrees and you're right back where you started > at i. > > It is this property of rotation that makes i so valuable in dealing with > things that rotate in space, the best example may be electromagnetism where > Maxwell used it to describe how electric and magnetic fields change in the > X and Y direction (that is to say in the Real and Imaginary direction) as > the wave propagates in the Z direction. > I'm not talking about why human beings find geometry useful. I am saying, IF the universe were purely functional, with no human beings, no consciousness even, why would geometry be useful to mathematics? Why would there even begin to be a theoretical underpinning for a universe which remotely resembles this one?
