The Cybernetics Society held its 26th Annual Conference at King's College London on 16 September 2000. A full day of papers and discussions included the following.

Prof. Koichiro Matsuno of the Nagaoka University of Technology, Japan, gave the keynote address on the Spontaneous Emergence of Life.

Chemical evolution leading to the emergence of life on our primitive Earth must have required the hardware facilitating the synthesis of oligomers from monomers in view of the fact that those monomers such as amino acids could already have been abundant there. A possible likely locale for synthesizing oligomers from monomers might have been hydrothermal environments in the Hadean ocean, that could maintain huge thermodynamic gradients against the surrounding cold seawater. Those thermodynamic gradients can drive various synthetic reactions relevant to chemical evolution.

A flow reactor was constructed that simulated a submarine hydrothermal system. When fluid containing glycine repeatedly circulated through the hot (about 250°C) and cold (0.5°C) regions in the reactor, oligopeptides were synthesized from glycine. When divalent ions (such as copper ions) were added under acidic conditions, oligopeptides were elongated up to octaglycine. When fluid containing mononucleotide AMP (adenosine monophosphate) repeatedly circulated through the hot (110°C) and cold (0.5°C), oligonucleotides up to trimers were synthesized. This observation suggests that prebiotic monomers could have oligomerized in the vicinity of submarine hydrothermal vents on primitive Earth. Once both oligopeptides and oligonucleotides are available, the experimental access to the emergence of life from the abiotic side can be further narrowed down.

Sunny Bains, scientist and journalist, talked about Physical Computation and Artificial Intelligence.

Traditional approaches to computation have proved extremely successful for some kinds of task, particularly those that humans do badly. However, it has been less easy to extend conventional computer technology to do the things we do well: digital computers are generally less efficient and robust than we would like them to be for many artificial intelligence applications. She discussed a class of "physical computers": devices that compute in a way that does not involve the conversion of physical signals into data (symbols) and back again. She considered various physical implementations and applications, the case for these machines being more biologically valid than their conventional counterparts, and their potential computational power (in the context of arguments by Penrose and Siegelmann).

Dr Peter Marcer, of the British Computer Society Cybernetic Machine Specialist Group, spoke on Quantum Holography, New Biology, Novel Technology, or What physicists can teach biologists and biology, physics.

In the 19th century it seemed that the whole of the Natural World could be described in terms of classical physics. In the 20th century, the new quantum physics was needed to supplement this picture in relation to microscopic phenomena, successfully explaining much of elementary particle physics. However, in the new millennium, such explanations will be extended to the entire structure of the whole Universe, cosmological, galactic, solar, planetary, geological, living and social, including the molecular biological, biological, neurological, psychological, noetic, medical, and even mathematical.

The key to such explanations is measurement ie the process of extraction of information, which is the basis of all experimental science and experience. An appropriate starting point is therefore the work of John von Neumann, in relation to measurement in quantum physics. This definition of measurement not only introduces the concepts of information and signal processing into quantum physics as integral phenomena of the natural world, it subsumes classical physics. This leads, he was convinced, to a Grand Unification of the Sciences, with new branches such as quantum cosmology, quantum biology, quantum neuroscience, quantum medicine, etc, within which are included the currently established classical understandings. This is a natural extension of the view, expressed by Feynman, that without quantum physics there can be no chemistry, and therefore by implication, no molecular biology, no biology, nor indeed any of the life sciences.

Examples were given that these classical understandings, however, represent most likely only one half of the full eventual scientific undertanding. In particular, experiments (Gariaev, 1994) carried out at the Institute of Control Sciences of the Moscow Academy of Sciences by the Peter Gariaev group were briefly described, which validate a model, the DNA-wave biocomputer, as the very basis of a quantum molecular biology and the corresponding quantum life sciences; and also, the work of Walter Schempp of Siegen University. His extended exploration of quantum holography via the mathematics of the Heisenberg Lie group as a means to incorporate signal theory into quantum physics (Schempp, 1986), together with this mathematical foundation's experimental validation by means of nuclear magnetic resonance imaging (MRI) machinery (Schempp, 1998), also provide an independently conceived mathematical quantum wavepacket explanation of the workings of DNA (Schempp, 1992, 1993, Marcer and Schempp, 1996) and by implication biology. And one that fits quite exactly into the framework of von Neurmann's quantum measurement theory, and the work carried out in Moscow. A particular claim and the experimental and theoretical evidence to be cited, is, that the currently established understanding of the genetic code based on DNA nucleotide basepairing to which mankind assigns the symbols A,U,C,G, is in fact, only one half of the full scientific story.

Dr Louis H. Kauffman, of the Department of Mathematics, University of Illinois at Chicago, talked about Symbiologic, Rational Knots, and DNA.

His talk began with the problem: How does DNA manage to reproduce, given that the two strands of the DNA are wound around one another, and may (in closed circular DNA) be linked? He outlined a proposal by himself and John Hearst that sheds light on this problem, that is part of a larger project they call "symbiologic" -- the relations between diagrammatic and logical schemata and the actions of molecular biology. Symbiologic includes the relationship between formalisms for self-reference, re-entry, self-reproduction and biology, self-activating automata (autopoeisis) and the uses of diagrammatic knot theory in studying DNA. He discussed the basics of the theory of rational tangles and rational knots in relation to DNA recombination, and ended with the description of a new proof of the classification of rational knots due to himself and Sofia Lambropoulou, and its relationship to DNA recombination.

Dr Ian White, of the Defence Evaluation and Research Agency, spoke about the Limits and Capabilities of Machines.

His talk was a review of fundamental limits of machines giving some emphasis to new developments in the physics of computers, and the relationship of physical and biological metaphores of computation. This was the fifth of a continuing series of papers on this thematic topic.

Dr Geraint A. Wiggins, of the Department of Computing, City University, London, gave a presentation about Musical Communication and Meaning, supported by audio demonstrations.

He introduced a range of issues related to the study of human musical behaviour in a context of cognitive science and, specifically, from the point of view of computational linguistics. He discussed, and gave examples of, different aspects of musical communication, and attempted, where appropriate, to contrast this with common practice in computational linguistics. His presentation served as an introduction to some of the issues involved in understanding musical communication and meaning. He gave some demonstrations of how musical content can be automatically controlled to convey particular emotional impressions.

Dr Daniel M. Dubois, of the Centre for Hyperincursion and Anticipation in Ordered Systems, University of Liège, Belgium, gave an Internet presentation from Liège, using a colourful on-screen text. His subject was a "Survey of Computing Anticipatory Systems with Incursion and Hyperincursion".

The main purpose of his paper was to show that anticipation is not only a property of biosystems but is also a fundamental property of physical systems.

For Newtonian mechanical systems as well as all quantum and relativist systems, the description by local differential equations is identical to the description by the global Maupertuis Least Action Principle, which states that the trajectory, given by an integral defined by initial and final states, is optimum. So the Aristotelian final cause is implicitly embedded in any system theory and model. Thus such systems are implicit anticipatory systems because they evolve, from an initial state, to a final state which is implicitly embedded in them. In an epistemic way, such implicit anticipatory systems evolve "as if they know their future".

Anticipation is embedded in physical systems. In electromagnetism, for example, a charge moving at velocity v' at time t' creates an electrical field travelling at the light speed c. The electrical field is the field of the charge at the distance r and time t, anticipated from the past distance r' and time t' = t - r'/c.

Strong and weak anticipations can be defined by incursive and hyperincursive systems..

Definition of an incursive discrete strong anticipatory system: an incursive discrete system is a system which computes its current state at time t, as a function F of its states at past times, ., t-3, t-2, t-1, present time, t, and even its states at future times t+1, t+2, t+3, .. x(t+1) = F(., x(t-2), x(t-1), x(t), x(t+1), x(t+2), .;p) where the variable x at future times t+1, t+2, . is computed in using the equation itself. Such an incursive system is self-referential because it computes its future states from itself and not from a model-based prediction.

Definition of an incursive discrete weak anticipatory system: a weak incursive system is a system which computes its current state at time t, as a function F of its states at past times, ., t-3, t-2, t-1, present time, t, and even its predicted states at future times t+1, t+2, t+3, .. x(t+1) = F (., x(t-2), x(t-1), x(t), x*(t+1), x*(t+2), .;p) where the variable x* at future times t+1, t+2, . are computed in using a predictive model of the system. Such weak anticipatory systems may be related to the Robert Rosen definition: "An anticipatory system is a system containing a predictive model of itself and/or of its environment, which allows it to change state at an instant in accord with the model's predictions pertaining to a latter instant".

Definition of a hyperincursive discrete anticipatory systems: a hyperincursive discrete anticipatory system is an incursive discrete anticipatory system generating multiple iterates at each time step.

It was shown that incursive and hyperincursive anticipatory systems could model properties of biosystems like free will, game strategy, theorem creation, etc. Anticipation is not only related to predictions but to decisions: hyperincursive systems create multiple choices and a decision process selects one choice. So, anticipation is not a final goal, like in cybernetics and system science, but is a fundamental property of physical and biological systems."
