The rules of this Blog involve some key assumptions: At some microscopic level, we assume that physical space, time and state are all, ultimately, discrete and deterministic. Further, we also assume that there are no physical infinities, infinitesimals, continuity, differentiability, nor any local sources of true non-deterministic behavior. Such concepts play no role in models we shall discuss. Thus, we assume that all information must have finite and discrete means of its representation and we assume that the evolution of state is governed by local, deterministic rules.
Given all of the constraints, we nevertheless wish to solicit posts to this blog. While we will not indulge in arguments about the ground rules, we believe that there are reasonable explanations as to how sub-microscopic systems, with all the constraints we are imposing, could nevertheless result in higher level processes that behave in ways consistent with the known laws of physics.
