Turing's Thesis and a More General Physical Principle

Recently, Matthew P. Szudzik posted an article to the arXiv  server that is entitled " Is Turing's Thesis the Consequence of a More General Physical Principle? " Szudzik ivnestigates Robert Rosen’s hypotheses, which were put forth in " Church’s thesis and its relation to the concept of realizability in biology and physics ". Roughly, one can say that these hypotheses state that the universe is discrete, deterministic, and computable.  A direct consequence of these hypotheses is the Church-Turing Thesis. Szudzik recognizes that these hypptheses are not correct and, thus, one needs to reformulate them: This sort of reformulation was first attempted by Konrad Zuse [18, 19] in the 1960’s. Since then, increasingly sophisticated attempts have been made by Edward Fredkin [3] and Stephen Wolfram [17]. In contrast, Roger Penrose [9, 10] has speculated that the universe might not be computable, but efforts to find experimental evidence for this assertion have not succee
