Karl Svozil (Univ. Vienna, Austria) has also some interesting views on the
subject. He pleads for a "discrete computational or algorithmic physics"
which systematically envisions the physical world as a discrete machine.
See for instance his introductory, well documented and sometimes strange
"Computational universes"
(item 5 at http://tph.tuwien.ac.at/~svozil/publ/publ.html )
