2013/2/5 Roger Clough <rclo...@verizon.net> Hi Alberto G. CoronaYour concept is incomplete, because geometry is what Plato calledforms,which he gave the Greek name of ideas. So you have a thoughtwithout a thinker.Yes, the greeks did not conceive an empty space without forms. Forthem it was the forms what created the space. They did no studiedspace geometry but the geometry of the forms. They did not conceivedthe infinite space. They don´t liked the concept,

`That's true for the earlier greeks, but with Plotinus (300 after JC),`

`infinity became respectable, both for matter and god.`

According with Spengler, this concept came from the nordic mithologyand solidified in the Gothic architecture.The greek concept is more primitive and therefore, is much moreintuitive and natural, because it descries space by what it is for:to perceive things and appreciate distances, proportions and shapes.

`Which I think is the correct and even modern (current) conception of`

`space (and time).`

And this is what whe perceive as"reality", that apears to be "out there".I mean 3D geometry. any other geometry either is mentaly transatedto 3D by projections or else, must be calculated non intuitively(non accelerated) 燽y means of algebraic formulas.However, I imagine that an advanced robot with fast spatialprocessing (based of algebraic formulas) would pass the turing testwhen asked about geometrical figures in space. It can even answer:"geometry is intuitive form me. My father-engineer gave me a goodfloating point coprocessor and good spatial algorithms.but there is a self reference when we try to imagine how the brainor a computer process geometry, and we imagine them embedded in thespace and time that they create, which is not a correct intuition.we must imagine it in no time and no space.

If geometry did not exist. Could you invent it with mathematics alone? And if you could do that... Why would you?For instance: A triangle can be defined mathematically in differentways, but without the inherently geometric presentations of linesand angles, it seems that all you could generate is a descriptionof a set of values which have the same relation as the values whichwould be present if a geometric shape were measured or sampled fromoptical or tactile detections.That is not to say that the list of mathematical definitions whichsatisfy triangularity (a^2 + b^2 = c^2 for example), even anexhaustive list, would suggest anything like the visible presenceof a shape. All of the mathematics can be done completely in thedark, and no realism of points, plots, displays, manifolds,topologies, etc, ever need to literally appear to anything.We don't know that.
