Mechanisms inducing parallel computation in a model of physarum polycephalum transport networks
The giant amoeboid organism true slime mould Physarum polycephalum dynamically adapts its body plan in response to changing environmental conditions and its protoplasmic transport network is used to distribute nutrients within the organism. These networks are efficient in terms of network length and network resilience and are parallel approximations of a range of proximity graphs and plane division problems. The complex parallel distributed computation exhibited by this simple organism has since served as an inspiration for intensive research into distributed computing and robotics within the last decade. P. polycephalum may be considered as a spatially represented parallel unconventional computing substrate, but how can this âcomputerâ be programmed? In this paper we examine and catalogue individual low-level mechanisms which may be used to induce network formation and adaptation in a multi-agent model of P. polycephalum. These mechanisms include those intrinsic to the model (particle sensor angle, rotation angle, and scaling parameters) and those mediated by the environment (stimulus location, distance, angle, concentration, engulfment and consumption of nutrients, and the presence of simulated light irradiation, repellents and obstacles). The mechanisms induce a concurrent integration of chemoattractant and chemorepellent gradients diffusing within the 2D lattice upon which the agent population resides, stimulating growth, movement, morphological adaptation and network minimisation. Chemoattractant gradients, and their modulation by the engulfment and consumption of nutrients by the model population, represent an efficient outsourcing of spatial computation. The mechanisms may prove useful in understanding the search strategies and adaptation of distributed organisms within their environment, in understanding the minimal requirements for complex adaptive behaviours, and in developing methods of spatially programming parallel unconventional computers and robotic devices
Biohacking and code convergence : a transductive ethnography
Cette thĂšse se dĂ©ploie dans un espace de discours et de pratiques revendicatrices, Ă lâinter- section des cultures amateures informatiques et biotechniques, euro-amĂ©ricaines contempo- raines. La problĂ©matique se dessinant dans ce croisement culturel examine des mĂ©taphores et analogies au coeur dâun traffic intense, au milieu de voies de commmunications imposantes, reliant les technologies informatiques et biotechniques comme lieux dâexpression mĂ©diatique. Lâexamen retrace les lignes de force, les mĂ©diations expressives en ces lieux Ă travers leurs manifestations en tant que codes âĂ la fois informatiques et gĂ©nĂ©tiquesâ et reconnaĂźt les caractĂšres analogiques dâexpressivitĂ© des codes en tant que processus de convergence.
Ămergeant lentement, Ă partir des annĂ©es 40 et 50, les visions convergentes des codes ont facilitĂ© lâentrĂ©e des ordinateurs personnels dans les marchĂ©s, ainsi que dans les garages de hackers, alors que des bricoleurs de lâinformatique sâen rĂ©clamaient comme espace de libertĂ© dâinformation âet surtout dâinnovation. Plus de cinquante ans plus tard, lâanalogie entre codes informatiques et gĂ©nĂ©tiques sert de moteur aux revendications de libertĂ©, informant cette fois les nouvelles applications de la biotechnologie de marchĂ©, ainsi que lâactivitĂ© des biohackers, ces bricoleurs de garage en biologie synthĂ©tique. Les pratiques du biohacking sont ainsi comprises comme des individuations : des tentatives continues de rĂ©soudre des frictions, des tensions travaillant les revendications des cultures amateures informatiques et biotechniques.
Une des maniĂšres de moduler ces tensions sâincarne dans un processus connu sous le nom de forking, entrevu ici comme lâexpĂ©rience dâune bifurcation. Autrement dit, le forking est ici dĂ©finit comme passage vers un seuil critique, dĂ©clinant la technologie et la biologie sur plusieurs modes. Le forking informe âcâest-Ă -dire permet et contraintâ diffĂ©rentes vi- sions collectives de lâouverture informationnelle. Le forking intervient aussi sur les plans des iii semio-matĂ©rialitĂ©s et pouvoirs dâaction investis dans les pratiques biotechniques et informa- tiques. Pris comme processus de co-constitution et de diffĂ©rentiation de lâaction collective, les mouvements de bifurcation invitent les trois questions suivantes : 1) Comment le forking catalyse-t-il la solution des tensions participant aux revendications des pratiques du bioha- cking ? 2) Dans ce processus de solution, de quelles maniĂšres les revendications changent de phase, bifurquent et se transforment, parfois au point dâaltĂ©rer radicalement ces pratiques ? 3) Quels nouveaux problĂšmes Ă©mergent de ces solutions ?
Lâeffort de recherche a trouvĂ© ces questions, ainsi que les plans correspondants dâaction sĂ©mio-matĂ©rielle et collective, incarnĂ©es dans trois expĂ©riences ethnographiques rĂ©parties sur trois ans (2012-2015) : la premiĂšre dans un laboratoire de biotechnologie communautaire new- yorkais, la seconde dans lâĂ©mergence dâun groupe de biotechnologie amateure Ă MontrĂ©al, et la troisiĂšme Ă Cork, en Irlande, au sein du premier accĂ©lĂ©rateur dâentreprises en biologie synthĂ©tique au monde. La logique de lâenquĂȘte nâest ni strictement inductive ou dĂ©ductive, mais transductive. Elle emprunte Ă la philosophie de la communication et de lâinformation de Gilbert Simondon et dĂ©couvre lâĂ©pistĂ©mologie en tant quâacte de crĂ©ation opĂ©rant en milieux relationnels. Lâheuristique transductive offre des rencontres inusitĂ©es entre les mĂ©taphores et les analogies des codes. Ces rencontres Ă©tonnantes ont amĂ©nagĂ© lâexpĂ©rience de la conver- gence des codes sous forme de jeux dâĂ©critures. Elles se sont retrouvĂ©es dans la recherche ethnographique en tant que processus transductifs.This dissertation examines creative practices and discourses intersecting computer and biotech cultures. It queries influential metaphors and analogies on both sides of the inter- section, and their positioning of biotech and information technologies as expression media. It follows mediations across their incarnations as codes, both computational and biological, and situates their analogical expressivity and programmability as a process of code conver- gence. Converging visions of technological freedom facilitated the entrance of computers in 1960âs Western hobbyist hacker circles, as well as in consumer markets. Almost fifty years later, the analogy drives claims to freedom of information âand freedom of innovationâ from biohacker hobbyist groups to new biotech consumer markets. Such biohacking practices are understood as individuations: as ongoing attempts to resolve frictions, tensions working through claims to freedom and openness animating software and biotech cultures.
Tensions get modulated in many ways. One of them, otherwise known as âforking,â refers here to a critical bifurcation allowing for differing iterations of biotechnical and computa- tional configurations. Forking informs âthat is, simultaneously affords and constrainsâ differing collective visions of openness. Forking also operates on the materiality and agency invested in biotechnical and computational practices. Taken as a significant process of co- constitution and differentiation in collective action, bifurcation invites the following three questions: 1) How does forking solve tensions working through claims to biotech freedom? 2) In this solving process, how can claims bifurcate and transform to the point of radically altering biotech practices? 3) what new problems do these solutions call into existence?
This research found these questions, and both scales of material action and agency, in- carnated in three extensive ethnographical journeys spanning three years (2012-2015): the first in a Brooklyn-based biotech community laboratory, the second in the early days of a biotech community group in Montreal, and the third in the worldâs first synthetic biology startup accelerator in Cork, Ireland. The inquiryâs guiding empirical logic is neither solely deductive or inductive, but transductive. It borrows from Gilbert Simondonâs philosophy of communication and information to experience epistemology as an act of analogical creation involving the radical, irreversible transformation of knower and known. Transductive heuris- tics offer unconvential encounters with practices, metaphors and analogies of code. In the end, transductive methods acknowledge code convergence as a metastable writing games, and ethnographical research itself as a transductive process
Spirit calls Nature: Bridging Science and Spirituality, Consciousness and Evolution in a Synthesis of Knowledge
This is a technical treatise for the scientific-minded readers trying to expand their intellectual horizon beyond the straitjacket of materialism. It is dedicated to those scientists and philosophers who feel there is something more, but struggle with connecting the dots into a more coherent picture supported by a way of seeing that allows us to overcome the present paradigm and yet maintains a scientific and conceptual rigor, without falling into oversimplifications. Most of the topics discussed are unknown even to neuroscientists, biologists, philosophers, and yet are based on the findings published in their own mainstream peer reviewed literature or on deep insights of the scientific, philosophical and spiritual giants of the past.
A scientific, philosophical, and spiritual overview of the relationship between science and spirituality, neuroscience and the mystery of consciousness, mind and the nature of reality, evolution and life. A plaidoyer for a science that goes beyond the curve of reason and embraces a new synthesis of knowledge. The overcoming of the limitations of the intellect into an extended vision of ourselves and Nature. A critique of physicalism, the still-dominant doctrine that believes that all reality can be reduced to matter and the laws of physics alone. A review and reassessment of the old and new philosophical and metaphysical ideas which attempts to bring closer Western and Eastern traditions where science, philosophy, consciousness, Spirit and Nature are united in a grand vision that transcends the limited conventional scientific and philosophical paradigm. A possible answer to the questions of purpose and meaning and the future evolution of humankind beyond a conception that posits a priori a purposeless and meaningless universe. A report of the new scientific discoveries of a basal intelligence in cells and plants, on the question if mind is computational, the issue of free will, the mind-body problem, and the so called âhard problem of consciousnessâ. An essay on ancient as modern philosophical conceptions, from the One of Plotinus, the God of Spinoza until the recent revival of panpsychism or the universal consciousness. A journey into quantum physics from the perspective of philosophical idealism and an invitation to adopt new ways of seeing that might help us to transform our present understanding, expanding it into an integral cosmology, with a special emphasis on the spiritual and evolutionary cosmology of the Indian seer Sri Aurobindo.
Not just a philosophical and metaphysical meditation but, rather, an appeal to work towards a change of consciousness, a widening of our perspective towards a new way of seeing beyond a purely mechanistic worldview to avoid a social, environmental and economic collapse. Humans are transitional beings that will have to make a choice: relapse into a pre-rational state or evolve towards a new trans-rational species supported by an ideal of human unity in diversity as the expression of a spiritual evolutionary process, the call of the Spirit on Nature
