Teleodynamics: Specifying the Dynamical Principles of Intrinsically End-Directed Processes | Terrence W. Deacon | IAISAE (2020)

ABSTRACT

Seven parameters are described that distinguish three hierarchically nested system dynamics that are characteristic of partially-bounded open subsystems. These are used to characterize the transition from self-organized inorganic to self-regulated living systems which exhibit self-synthesis, self-reproduction, and self-reconstitution in response to damage. This analysis demonstrates that yoked self-organizing processes that generate each-others’ boundary conditions can produce a form of co-dependent unity that exhibits these end-directed properties. A simple empirically testable molecular model system — an autogenic virus — is described for exploring these dynamical properties.

Keywords: organism, constraint, dissipative processes, self-organization, morphodynamics, autogenesis, MEPP, virus

Thermodynamics today | Prof. Adrian Bejan

In this paper I use the example set by Prof. Jan Szargut as point of reference for a brief look at the current state of thermodynamics—the doctrine, its reach and importance. I start with my first encounter with Prof. Jan Szargut in 1979, and I show how his work influenced mine. Next, I review the structure that underpins thermodynamics as a discipline: the laws and the self-standing phenomena that they underpin, and graphic methods that convey these principles. Along the way, I draw attention to a recent trend that is caused by the inflation in scientific publishing due to the internet: the most common mistakes and misconceptions in thermodynamics, and how they are being spread. In sum, this paper is a call to action, to value, improve and defend the science of thermodynamics. Read More
