And in PDF? (a solution appears in the horizon for putting it in PDF
format in my URL)

OK. But I reserve platonic existence to numbers and their (intricate
enough) relations. The "whole of math" is not a well defined
being, it seems to me. See also my post to Chris.
And there is a difference which remains to explain between the
atemporal universal Turing machine and the apparently
contingencial concrete universal computer I am using right now.
A lot of people seems to take mathematical reality for granted.
They should realise that the very mathematical discovery of the
computer (by Post, Turing, Church, Markov, etc.) comes from
works in the foundation of math, when all attempt to define the
"whole math" appears to be inconsistent ... or incomplete.
