III. Ecosmos: A Revolutionary Fertile, Habitable, Solar-Bioplanet, Incubator LifescapeC. The Information Computation Turn Khrennikov, Andrei. Towards Information Lasers. Entropy. Online October, 2015. The prolific Linnaeus University physicist continues his project, with many colleagues, to reconceive quantum phenomena in terms of an intrinsic communicative quality. The article is also a good entry to this 21st century fundamental revolution. In our modeling, the notion of information is a primary notion, which is not definable with the aid of more fundamental notions, such as probability. Such an approach matches various purely-informational approaches to physics celebrated in Wheeler’s statement: “It from bit. Otherwise put, every ‘it’, every particle, every field of force, even the space-time continuum itself derives its function, its meaning, its very existence entirely - even if in some contexts indirectly from the apparatus-elicited answers to yes-or-no questions, binary choices, bits. ‘It from bit’ symbolizes the idea that every item of the physical world has at bottom—a very deep bottom, in most instances—an immaterial source and explanation; that which we call reality arises in the last analysis from the posing of yes no questions and the registering of equipment-evoked responses; in short, that all things physical are information-theoretic in origin and that this is a participatory universe.” (6975) Kitazono, Jun, et al. Efficient Algorithms for Searching the Minimum Information Partition in Integrated Information Theory. Entropy. 20/3, 2018. As this IIT approach (Tononi) whence consciousness is seen to rise in tandem with relative knowledge content grows in acceptance, Kitazono, Araya, Inc., Tokyo, Ryota Kanai, Kobe University, and Masafumi Oizumi (search), RIKEN Brain Science Institute, Hiroshima press its technical advance via algorithms and neural nets by which to better analyze and apply. See also concurrent papers Measuring Integrated Information by Pedro Mediano, et al at arXiv:1806.09373, and Integrated Information in the Thermodynamic Limit by Miguel Aguilera and Exequiel Di Paolo at 1806.07879. A good entry to ITT is What is Consciousness? by co-theorist Christoph Koch in Scientific American for June 2018. The ability to integrate information in the brain is considered to be an essential property for cognition and consciousness. Integrated Information Theory (IIT) hypothesizes that the amount of integrated information in the brain is related to the level of consciousness. (Abstract) Knuth, Kevin. Information-Based Physics: An Observer-Centric Foundation. Contemporary Physics. Online January, 2014. The SUNY Albany professor of physics and informatics continues the inspiration of John Archibald Wheeler that this existent reality is in some way founded upon and most distinguished by a communicative source and conveyance. Such a self-visualizing and activating cosmos then requires at a later point the presence of sentient observers to recognize, acknowledge, and so bring into full being. Knuth has a series of prior papers on arXiv such as The Physics of Events: A Potential Foundation for Emergent Space-Time. While they, and most theoretical papers, are written in a technical parlance, the point of the message could be that human beings are in fact significantly empowered and entitled to learn, discover, witness and self-select. It is generally believed that physical laws, reflecting an inherent order in the universe, are ordained by nature. However, in modern physics the observer plays a central role raising questions about how an observer-centric physics can result in laws apparently worthy of a universal nature-centric physics. Over the last decade, we have found that the consistent apt quantification of algebraic and order-theoretic structures results in calculi that possess constraint equations taking the form of what are often considered to be physical laws. The result is an approach to foundational physics where laws derive from both consistent descriptions and optimal information-based inferences made by embedded observers.

An historic paper by the German-American, IBM Research Center, physicist which established the concept that something else and more is going on than just material in motion. It is here that early claims of “quantum information,” along with “quantum parallelism and analog computation” are entered. Lingam, Manasvi, et al. Planetary Scale Information Transmission in the Biosphere and Technosphere: Limits and Evolution. arXiv:2309.07922. ML, Florida Institute of Technology, Adam Frank, University of Rochester and Amedeo Balbi, University of Rome astroscholars provide insightful suggestions to better serve our future searches for advanced, neighbor exoworlds. In regard, they propose this natural and human knowledgeable, communicative quality can be a prime indicator of their presence. Once more, in still another view, this immaterial, implicate feature can well define the central course of life, mind and personal procreativity.
Linson, Adam, et al. The Active Inference Approach to Ecological Perception: General Information Dynamics for Natural and Artificial Embodied Cognition. Frontiers in Robotics and AI. Online March, 2018. In this paper with many views, senior British neuroscientists and philosophers Linson, Andy Clark, Subramanian Ramamoorthy and Karl Friston continue to voice their future oriented, anticipatory model of neural activity. In other words, our brains are most occupied with and distinguished by trying to figure out what happens next, and by referral to prior memory how to respond. The technical paper courses through physical thermodynamics, self-organizing systems, embodiment, adaptations, and onto complex spatial/temporal integration so to express a universe to human evolution which seems to be engaged with and bent on its own successful recognition. OK The emerging neurocomputational vision of humans as embodied, ecologically embedded, social agents who shape and are shaped by their environment offers an opportunity to revisit ideas about the physical and information-theoretic underpinnings of life, mind, and consciousness itself. In particular, the active inference framework (AIF) makes it possible to bridge connections from computational neuroscience and robotics/AI to ecological psychology and phenomenology, revealing common underpinnings and overcoming limitations. AIF opposes the mechanistic and reductive, while staying grounded in a naturalistic and information-theoretic foundation, using the principle of free energy minimization. This approach allows a unified treatment of particles, organisms, and interactive machines, spanning from the inorganic to organic, non-life to life, and natural to artificial agents. (Abstract edits) Lizier, Joseph. JIDT: An Information-Theoretic Toolkit for Studying the Dynamics of Complex Systems. arXiv:1408.3270. We note this contribution by the University of Sydney researcher because it describes these ubiquitous nonlinear networks as most distinguished by their conveyance of an informational content. By such an attribution, nature’s universal self-organizational propensities seem to take on a genetic identity. Complex systems are increasingly being viewed as distributed information processing systems, particularly in the domains of computational neuroscience, bioinformatics and Artificial Life. This trend has resulted in a strong uptake in the use of (Shannon) information-theoretic measures to analyse the dynamics of complex systems in these fields. We introduce the Java Information Dynamics Toolkit (JIDT): a Google code project which provides a standalone, (GNU GPL v3 licensed) open-source code implementation for empirical estimation of information-theoretic measures from time-series data. While the toolkit provides classic information-theoretic measures (e.g. entropy, mutual information, conditional mutual information), it ultimately focusses on implementing higher-level measures for information dynamics.

Lloyd, Seth.
Programming the Universe.
New York: Knopf,
2006.
The MIT ‘quantum mechanic’ writes his book, which illustrates a deep dichotomy in physics. The main difference pertains to the presence and activity of information. As opposed to approaches such as string theory or loop quantum gravity which do not include information as a prime actor, Lloyd could be placed in the digital universe camp, populated by Stephen Wolfram, Gregory Chaitin and others, who hold that an original and constant algorithmic program is at work to generate an increasing, animate complexity. (One could also mention Eric Baum and Richard Watson.) This view adds another aspect akin to an elemental software which applies over and over as the cosmos computes itself. This book advocates a new paradigm, an extension of the powerful mechanistic paradigm: I suggest thinking about the world not simply as a machine, but as a machine that processes information. In this paradigm, there are two primary quantities, energy and information, standing on an equal footing and playing off each other. (169) The primary consequence of the computational nature of the universe is that the universe naturally generates complex systems, such as life. Although the basic laws of physics are comparatively simple in form, they give rise, because they are computationally universal, to systems of enormous complexity. (176) Lloyd, Seth. The Digital Universe. Physics World. November, 2008. Reviewed at length in Quantum Cosmology as a synopsis of this computational school. Loewenstein, Werner. Physics in Mind: A Quantum View of the Brain. New York: Basic Books, 2013. The emeritus Columbia University physiologist, biophysicist and philosopher follows up his >the Touchstone of Life (2000, search) with an expansive cosmic scenario defined by the temporal flight of an informational vector. A “first arrow” is shot from the big bang by way of atomic, chemical matter. Then a “second information arrow” flies as life evolves, quickens and awakens via complexity and consciousness – “an evolutionary process that generates its own information repository to progressively reduce the element of chance.” An order emerges from a relative, contingent randomness to developing macroscopic realms of intentional sentience. One man’s technical take, as if trying to describe a cosmic elephant, but once again it reflects a regnant genetic genesis is extolled from universe to human. So heaven’s vault is crisscrossed with information arrows. The arrows hailing from out there are long – some have been on the fly for nearly 14 billion years. Those are the lines of information issuing from the primordial kernel, the initial state of information in the universe. Eventually that initial state led, in the course of the universe’s expansion, to the condensation of matter locally and the formation of galaxies, as we have seen: as those vast structures evolved, more and more structures – stars, planets, moons, etc. – formed inside them. From our perch in the universe, we ordinarily get to glimpse only segments of the arrows, - local arrowlets, we might say. We therefore easily lose sight of the continuity. But as we wing ourselves high enough, we see that those arrowlets get handed down from system to system: from galaxy to stars to planets…to us. (21) Loewenstein, Werner. The Touchstone of Life. New York: Oxford University Press, 1999. A veteran biochemist contends that information and its communicative flow is the fundamental essence of life as it evolves from molecules to sentient mind. In an expansive survey, the book describes recursive circles in internal cellular communication, external intercellular networks, and in neuronal webs which are seen to foster an informed consciousness. Such content evolves by a principle of information economy on a path of least cost. Information means something different in science from what it does in everyday language - something deeper. It connotes a cosmic principle of organization and order… (xvi) And this, the principle of information economy of self-developing systems, I submit, is the guiding principle of biological evolution. (xvii) …there is the trend of ever-increasing information as life climbs the phylogenetic rungs - what actually evolves is information in all its forms and transforms. (94) Lutz, Eric and Sergio Ciliberto. Information: From Maxwell’s Demon to Landauer’s Eraser. Physics Today. September, 2015. In a historic 1991 paper, physicist Rolf Landauer (search) theorized that in some deep way physical materiality is suffused with an active information content. This paper by a German and a French physicist reviews the original conception and the latest proofs of its actual veracity.
