by Joël de Rosnay . Let us use the macroscope to direct a new look at nature, society, and man observes in the macroscope the organism that shelters it. Joël de Rosnay, (born 12 June ) is Docteur ès Sciences and scientific writer, presently On these subjects, he wrote: “Le Macroscope” (), “Les Chemins de la Vie” (The paths of life) () and “Le Cerveau Planétaire” (The planetary. Editions du Seuil, The complete book on a “The Macroscope” by Joël de Rosnay – Old but very good.

It gives rise to a sense of timingthe knowing when to begin an action, neither too soon nor too late, but at the precise moment the system is ready to move in one direction or the other. However, in the case of nonlinear interactions the variables are multiplied or divided by coefficients macroscole are themselves functions of other variables.

At the level of the world economy the growth race entails social inequalities, depletion of resources, and pollution.

Data sent out by a command center can be amplified in significant proportions, especially when the data are relayed by the hierarchical structures of organizations or by diffusion networks. As Dennis Meadows observed, however, the only alternatives roenay “mental models” made from fragments of elements and intuitive thinking see notes.

Want to Read saving…. T can be changed to-T without modifying the phenomena under study.

Only union through diversity is creative; it increases complexity and leads to higher levels of organization. Through the Macroscope 1. Food and world population.

It consists of an aggregation of flow variables: The limits are well known. The life of this body is maintained by the great ecological and economic functions brought together in the ecosphere.


The process of thought is at once analytic and synthetic, detailed and holistic.

The Macroscope-intro

On the other hand, a cell-a complex system-includes a large variety of organized elements in tight interaction with one another. Trivia About Le Macroscope: From this Wiener inferred that in order to control a finalized action an action with a purpose the circulation of information needed for control must form “a closed loop allowing the evaluation of the effects of one’s actions and the adaptation rosnsy future conduct based on past performances.

Refresh and try again. A closed system exchanges neither energy nor matter nor information with its environment; it is totally cut off from the outside world.

At the conclusion of the work of his group on the organization of the cortex of the brain, and especially after his discussions with Walter Pitts, a brilliant, twenty-two-year-old mathematician, McCulloch understood that a beginning of the comprehension of cerebral mechanisms and their simulation by machines could come about only through the cooperation of many disciplines.

By acting at this level, one releases either amplifications or controlled inhibitions.

World resources of food grow at a constant rate a linear, arithmetic progressionwhile world population grows at a rate that is itself a function of population a nonlinear, geometric progression see notes Fig.

The system uses its own internal reserve of potential energy. Attali remarked on this at a meeting of the Group of Ten devoted to the maintenance of biological and social equilibriums: A simulator, which is an interactive physical model, can also be used to give in “real time” the answers to different decisions and reactions of its user.

There are flows of money salaries in dollars per monthfinished products number of cars coming off the assembly line by the day or the monthpeople number of travelers per hourinformation so many bits of information per microsecond in a computer. Other groups were formed in the United States and around the world, notably the Society for General Systems Research, whose publications deal with disciplines far removed macgoscope engineering, such as sociology, political science, and psychiatry.


One must keep in mind that open system and ecosystem or environment are in constant interaction, each one modifying the other and being modified in return Fig. Major political decisions usually macrocope on such mental models.

This mode can lead to the destruction of the system if the disturbances persist. The laws of the additivity of elementary properties do not apply in highly complex systems composed of nacroscope large diversity of elements linked together by strong interactions. The fight against insects leads as well to the disappearance of the birds that feed on the insects; the result in the long term is that the insects return in full force-but there are no birds.

The functional aspect concerns process, or the phenomena dependent on time exchange, transfer, flow, growth, evolution ; this is temporal organization.

One may then extract and identify the flow variables, the state variables, positive and negative feedback loops, delays, sources, and sinks. Cybernetics has in fact the same root as government: There are definitions of the word system other than that given at the beginning of this chapter. The best results came from a policy roznay, a combination of measures used at the same time:
