Abstract
We suggest to consider the spacetime as a non-equilibrium system with a long-term stationary state that possess as a spatio-temporally fluctuating quantity ß . These systems can be described by a superposition of several statistics, “superstatistics”. We propose a Gamma distribution for f( [...] Read more.
We suggest to consider the spacetime as a non-equilibrium system with a long-term stationary state that possess as a spatio-temporally fluctuating quantity ß . These systems can be described by a superposition of several statistics, “superstatistics”. We propose a Gamma distribution for f(ß) that depends on a parameter ρ1. By means of it the corresponding entropy is calculated, ρ1 is identified with the probability corresponding to this model. A generalized Newton’s law of gravitation is then obtained following the entropic force formulation. We discuss some of the difficulties to try to get an associated theory of gravity. Full article

Cybersemiotics, in forging a new philosophy of science, addresses the failure of all disciplines to recognize and adequately account for qualia and motivation, interrogates the status of ‘knowing’ contra the computational information-processing paradigm, and explores the role of the observer in knowing. The present article discusses these key features of cybersemiotics and, in particular, their consequences for biosemiotics (to which cybersemiotics is a contributor). It argues that the constructivist basis of ‘languaging’ in the cybersemiotic project presents a potential impediment. It suggests that although ‘language’ is clearly in question in conceptualizing ‘knowing’ and ‘observing’, the main issue for cybersemiotics has to do with the more general process of ‘modelling’ that features in biosemiotics. Whilst the future of research in the sphere of biosemiotics will be enhanced by a greater understanding of ‘observership’, the article argues that aspects of the relationship of constructivism and realism will need to be made clear, and that the tools for this are available closer to cybersemiotics’ home in general semiotics.

This review presents results obtained from our group’s approach to model quantum mechanics with the aid of nonequilibrium thermodynamics. As has been shown, the exact Schrödinger equation can be derived by assuming that a particle of energy is actually a dissipative system maintained in a nonequilibrium steady state by a constant throughput of energy (heat flow). Here, also other typical quantum mechanical features are discussed and shown to be completely understandable within our approach, i.e., on the basis of the assumed sub-quantum thermodynamics. In particular, Planck’s relation for the energy of a particle, the Heisenberg uncertainty relations, the quantum mechanical superposition principle and Born’s rule, or the “dispersion of the Gaussian wave packet”, a.o., are all explained on the basis of purely classical physics.
