Pross, Addy. How Can a Chemical System Act Purposefully? Bridging Between Life and Non-Life. Journal of Physical Organic Chemistry. 21/7-8, 2008. Endorsed by Stuart Kauffman, the Ben-Gurion University chemist provides his latest views on an apparent innate propensity of chemical matter to spontaneously give rise to life’s ramifying evolution. This Abstract tells how and why.
One of life's most striking characteristics is its purposeful (teleonomic) character, a character already evident at the simplest level of life - a bacterial cell. But how can a bacterial cell, effectively an aqueous solution of an assembly of biomolecules and molecular aggregates within a membrane (that is itself a macromolecular aggregate), act purposefully? In this review, we discuss this fundamental question by showing that the somewhat vague concept of purpose can be given precise physicochemical characterization, and can be shown to derive directly from the powerful kinetic character of the replication reaction. At the heart of our kinetic model is the idea that the stability that governs replicating systems is a dynamic kinetic stability, one that is distinctly different to the thermodynamic stability that dominates the inanimate world. Accordingly, living systems constitute a kinetic state of matter as opposed to the thermodynamic states that dominate the inanimate world. Thus, the model is able to unite animate and inanimate within a single conceptual framework, yet is able to account for life's unique characteristics, amongst them its purposeful character. As part of that unification, it is demonstrated that key Darwinian concepts are special examples of more general chemical concepts. (Abstract)

Georgia Tech engineering theorists (search Haddad) post an intensely mathematical treatise for a later 2010s embellishment of natural, generative energies, broadly conceived, that make the cosmos and world go. We add quotes to help convey its essence and intent. Apropos the third entry, as scientists seek to unite atomic and astral realms, how might our middle/meso humankinder quantification be of equal cosmic import?
In this paper, we develop an energy-based, large-scale dynamical system model driven by Markov diffusion processes to present a unified framework for statistical thermodynamics predicated on a stochastic dynamical systems formalism. Specifically, using a stochastic state space formulation, we develop a nonlinear stochastic compartmental dynamical system model characterized by energy conservation laws that is consistent with statistical thermodynamic principles.

Critical, power-law behavior in space and/or time manifests in a large variety of complex systems within physics and, nowadays, more conspicuously in other fields, such as biology, ecology, geophysics, and economics. Universality, the same power-law holding for completely different systems, is a consequence of the characteristic self-similar, scale-invariant property of criticality… (63)
Rubi, J. Miguel. The Long Arm of the Second Law. Scientific American. November, 2008. The University of Barcelona physicist allows that although the cosmic tide of entropy surely flows, complexity and consciousness may arise via open non-equilibrium systems. Which seems basically the theoretical case made by Ilya Prigogine and colleagues some thirty years ago.
Waste is unavoidable—a sad fact of life quantified by the famous second law of thermodynamics. But if the world is steadily becoming more disordered, how do you explain the self-organization that often occurs in nature? At root, the trouble is that classical thermodynamics assumes systems are in equilibrium, a placid condition seldom truly achieved in the real world. A new approach closes this loophole and finds that the second law holds far from equilibrium. But the evolution from order to disorder can be unsteady, allowing for pockets of self-organization. (63)
Sagawa, Takahiro. Thermodynamics of Information Processing in Small Systems. Berlin: Springer, 2012. Due by November, a Kyoto University professor publishes his “best University of Toyko physics thesis of 2010.” As its synopsis notes, the work is seen as a novel formulation of a “nonlinear informational thermodynamics.”
This thesis presents a general theory of nonequilibrium thermodynamics for information processing. Ever since Maxwell's demon was proposed in the nineteenth century, the relationship between thermodynamics and information has attracted much attention because it concerns the foundation of the second law of thermodynamics. From the modern point of view, Maxwell's demon is formulated as an information processing device that performs measurement and feedback at the level of thermal fluctuations. By unifying information theory, measurement theory, and the recently developed theory of nonequilibrium statistical mechanics, the author has constructed a theory of "information thermodynamics," in which information contents and thermodynamic variables are treated on an equal footing. One of the generalized equalities has recently been verified experimentally by using sub-micron colloidal particles. (Publisher)

A survey of the history of thermodynamic thinking from the 19th century to its nonequilibrium ability today to articulate a fertile cosmos of open planetary systems becoming increasingly alive.
Instead of a second law portending the doom of life and the heat death of the universe, we propose an interpretation of the second law as an active participant in the emergence and evolution of dynamic dissipative systems. (50)
Schneider,, Eric and Dorion Sagan. Into the Cool: Energy Flow, Thermodynamics, and Life. Chicago: University of Chicago Press, 2005. Schneider, a veteran theorist of thermodynamics and ecology, and noted science writer Sagan join forces to achieve a novel synthesis of energy dynamics in life's origin, evolution and human affairs. In its broad compass, 19th century classical thermodynamics of a closed nature tending to equilibrium, codified in its second law which a cosmic heat death is lately superseded by a non- and far-from-equilibrium version. Living systems are actually open to a constant flow of energy and information which drives and sustains their complex viability and evolution. In order to give a proper appreciation we next quote from the publisher's website.
Scientists, theologians, and philosophers have all sought to answer the questions of why we are here and where we are going. Finding this natural basis of life has proved elusive, but in the eloquent and creative Into the Cool, Eric D. Schneider and Dorion Sagan look for answers in a surprising place: the second law of thermodynamics. This second law refers to energy's inevitable tendency to change from being concentrated in one place to becoming spread out over time. In this scientific tour de force, Schneider and Sagan show how the second law is behind evolution, ecology,economics, and even life's origin.

A special issue of papers from the 2006 The Second Law of Thermodynamics: Foundations and Status symposium, which the University of San Diego physicist edits. Grouped under three themes - ideal gases, quantum aspects, and interpretations - half support the 19th century inviolable axiom while the others post 21st century challenges. Sheehan’s contribution adds to chemosynthetic and photosynthetic life a third viable category that draws on available environmental heat sources.
Skene, Keith. Life’s a Gas: A Thermodynamic Theory of Biological Evolution. Entropy. Online July, 2015. The author has a doctorate in plant developmental biology from the University of Dundee, where he taught for 13 years. He is now director of the Biological Research Institute, a British virtual centre for global sustainability (BIOSRI). Its aim is an innovative synthesis of living, ecological systems with the natural vectors of energy and entropy. These dynamics are then seen in effect from DNA and amino acids all the way to biomes and the whole Earth system. An update is In Pursuit of the Framework behind the Biosphere in Biosystems (Vol. 190, 2020). The basic incentive is to get a read and bead on an evident innate motive force which strongly seems to drive life’s evolutionary advance and planetary florescence.
This paper outlines a thermodynamic theory of biological evolution. Beginning with a brief summary of the parallel histories of the modern evolutionary synthesis and thermodynamics, we use four physical laws and processes (the first and second laws of thermodynamics, diffusion and the maximum entropy production principle) to frame the theory. Given that open systems such as ecosystems will move towards maximizing dispersal of energy, we expect biological diversity to increase towards a level representing maximum entropic production. Based on this theory, we develop a mathematical model to predict diversity over the last 500 million years. This model combines diversification, post-extinction recovery and likelihood of discovery of the fossil record. We compare the output of this model with that of the observed fossil record. The model predicts that life diffuses into available energetic space (ecospace) towards a dynamic equilibrium, driven by increasing entropy within the genetic material through diffusion into available ecospace. Finally we compare and contrast our thermodynamic theory with the MES in relation to a number of important characteristics of evolution (progress, evolutionary tempo, form versus function, biosphere architecture, competition and fitness).

Smith, Eric. Thermodynamics of Natural Selection. Journal of Theoretical Biology. 252/2, 2008. This is the title of three linked papers with these subtitles: Energy Flow and the Limits on Organization; Chemical Carnot Cycles; and Landauer’s Principle in Computation and Chemistry. The abstract below from the first paper gives an overview. See also Smith’s popular article “Before Darwin” in The Scientist cited in the An Organic Universe section.
This is the first of three papers analyzing the representation of information in the biosphere, and the energetic constraints limiting the imposition or maintenance of that information. Biological information is inherently a chemical property, but is equally an aspect of control flow and a result of processes equivalent to computation. The current paper develops the constraints on a theory of biological information capable of incorporating these three characterizations and their quantitative consequences. The paper illustrates the need for a theory linking energy and information by considering the problem of existence and resilience of the biosphere, and presents empirical evidence from growth and development at the organismal level suggesting that the theory developed will capture relevant constraints on real systems. The main result of the paper is that the limits on the minimal energetic cost of information flow will be tractable and universal whereas the assembly of more literal process models into a system-level description often is not. The second paper in the series then goes on to construct reversible models of energy and information flow in chemistry which achieve the idealized limits, and the third paper relates these to fundamental operations of computation.

Big history can also be summarized as providing an overview of the rise and demise of complexity in all its forms and manifestations ever since the beginning of the universe. If we want to pursue this approach to big history, we need a theoretical framework that facilitates us to do so. In this article I propose such a scheme based on energy flows through matter that are needed for complexity to emerge, and often also to continue to exist, within certain favorable boundaries.
