Andrew Hodges, the author of that article about Turing, is
a mathematical physicist.  Among the issues he addresses are
Turing's comments about computability over the integers and
the real numbers.  Those questions are significant for any
computational ontology about space-time and the universe.    (02)

Hodges notes that Turing was (and still is) ahead of his time
in thinking about those problems.  That poem hints at them.    (03)

Hodges' also cites a web site about the *amplituhedron* :

This is just one of many, many reasons why I'm highly skeptical
about any proposals for a universal foundation ontology.  A new
discovery can pop up at any time that completely revolutionizes
and *obsoletes* any supposedly "ideal" foundation.    (06)
