Svozil, Karl; The Church-Turing thesis as a guiding principle for physics: Two aspects of the physical side of the Church-Turing thesis are discussed. The first issue is a variant of the Eleatic argument against motion, dealing with Zeno squeezed time cycles of computers. The second argument reviews the issue of one-to-one computation, that is, the bijective (unique and reversible) evolution of computations and its relation to the measurement process., Comment: 15 pages, latex, no figures [Text] [View with Perseus links] (0.88)
