Système complexe adaptatif
Un article de Wikipédia, l'encyclopédie libre. Complex Adaptive System Un système complexe adaptatif ou système complexe auto-adaptatif est l'ensemble des cas particuliers d'un système complexe capable de s'adapter à son environnement par des expériences d'apprentissage. Le terme anglais complex adaptive systems (CAS) a été introduit par l'Institut interdisciplinaire de Santa Fe notamment par John H. Holland et Murray Gell-Mann. Observations[modifier | modifier le code] En 1962, Vero Copner Wynne-Edwards a observé la sélection de groupe à l’œuvre dans les communautés d’oiseaux sauvages. Par ailleurs, David Sloan Wilson (en) a démontré qu’un réseau social qui applique les règles du « système adaptatif complexe » constitue la plus puissante machine à apprendre et gagne presque à tous les coups[1].

Synaptic Web | Collective Web
In previous posts, especially in those related to content mapping, I frequently referred to collective actions and efforts in describing certain concepts, but never elaborated on the exact meaning of these terms. One could think that collectivity and collaboration are identical (they often are mentioned in the same context) as both have something to do with individuals working together. In fact, I find it important to highlight their differences for I expect collectivity to play as vital a role in Web 3.0 as collaboration did in Web 2.0. Transition As already understood from popular Web 2.0 applications such as Wikipedia, Google Docs, or WordPress, we define collaboration as sharing workload in a group of individuals who engage in a complex task, working towards a common goal in a managed fashion, and are conscious of the process’ details all the way. Different realms Collaboration and collectivity operate in different realms. The synaptic web Hence the synaptic web calls for collectivity.
Structure du cerveau
Sommaire Structure du cerveauLa mémoireLe sommeilLa fatigue Retour à Conseils pour la santé Le cerveau est la structure la plus complexe de l’univers. Celle-ci se caractérise par l’existence de prolongements, dont les uns apportent des informations au neurone (les dendrites), alors que les autres communiquent les informations recueillies par le neurone (les axones). Si quelque jour, passant par le Berry, vous avez l’occasion de visiter la cathédrale St Etienne de Bourges, vous pourrez y observer la superposition de trois édifices successifs : une crypte ancienne d’une grande simplicité, surmontée d’un chœur roman aux voûtes encore incertaines ; enfin surmontant le tout et l’enveloppant de toutes parts, l’admirable église gothique avec ses 5 vaisseaux de lumière s’élançant vers le ciel. Au cours de l’évolution, des premiers vertébrés à l’homme, sont apparus 3 cerveaux superposés : · le cerveau dit reptilien ou diencéphale, qui assure la régulation de notre vie végétative. (J.M. (P.

Space, Time and Everything In Between: William Kentridge: Thick Time at the Whitechapel Gallery
The Refusal of Time, part of William Kentridge’s exhibition at the Whitechapel Gallery. A 2012 film still, made in collaboration with Philip Miller, Catherine Meyburgh and Peter Galison, Courtesy of William Kentridge, Marian Goodman Gallery, Goodman Gallery and Lia Rumma Gallery. Born in Johannesburg in 1955, William Kentridge grew up in apartheid South Africa, the son of two lawyers. His show Thick Time, at the Whitechapel Gallery until January 15 2017, features his work from the last 13 years and is his first major show in the UK in 15 years. The Refusal of Time, inspired by his conversations with American scientist Peter Galison about the theories of time, is the first piece in the exhibition. An Orwellian voice says something about the pips on the radio and the phrase “Here I am” is repeated over and over until its meaning becomes unclear. Second-Hand Reading is the most moving piece in the show.
Monsanto’s Dirty Dozen | GMO Awareness
When you take a moment to reflect on the history of product development at Monsanto, what do you find? Here are twelve products that Monsanto has brought to market. See if you can spot the pattern… #1 – Saccharin Did you know Monsanto got started because of an artificial sweetener? After mounting pressure from consumers, the Calorie Control Council, and manufacturers of artificial sweeteners and diet sodas, along with additional studies (several conducted by the sugar and sweetener industry) that reported flaws in the 1970s studies, saccharin was delisted from the NIH’s Carcinogen List. #2 – PCBs During the early 1920s, Monsanto began expanding their chemical production into polychlorinated biphenyls (PCBs) to produce coolant fluids for electrical transformers, capacitors, and electric motors. After another decade of studies, the truth could no longer be contained: the U.S. #3 – Polystyrene #4 – Atom bomb and nuclear weapons #6 – Dioxin #7 – Agent Orange (Think that can’t happen here? P.S.
