MACROSCOPE ROSNAY PDF

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.

During the fifties a tool was developed and perfected that would permit organized complexity to be approached from a totally new angle-the computer. Macroxcope correction of the body’s equilibrium when we stand is accomplished by the contraction of certain muscles without our having to think about it even when the brain intervenes.

The demographic curve stabilizes in an S curve, typical of growth limited by an outside factor Fig.

“The Macroscope”, a book on the systems approach

The theoretical basis was provided by his research on the eye of the frog, performed in in collaboration with Lettvin, Maturana, eosnay Pitts. There was also a strange defect in performance: They circulate through the networks of communication and are represented symbolically by a heavy black arrow flows of information are indicated by a dotted-line arrow.

This is the work of a positive feedback loop, working toward infinity or toward zero. To understand better these properties and to anticipate better its behavior. Thus the concept of system appears in two complementary aspects: Model building involves the construction of a model from data provided by systems analysis. A balance of flow is a dynamic equilibrium.

It is better to try to understand the internal dynamics of the system and to anticipate delays in response. One establishes first roshay complete diagram of the causal relations between the elements of the subsystem. The earth shelters the embryo of a body and the beginnings of a spirit. In this famous melting pot, ideas boiled.

The work of A. The laws of the additivity of elementary properties do not apply in highly complex systems composed of a large diversity of elements linked together by strong interactions. Therefore, we have made it again available on the web. To preserve stability one must preserve variety. The results of simulation must not be confused with reality as is often the case but, compared with what one knows of reality, should be used as the basis for the possible modification of the initial model. The symbolic representation of a reservoir is a simple rectangle.

For a complex system, to endure is not enough; it must adapt itself to modifications of the environment and it must evolve.

Two factors are important: Ross Ashby is “the number of different elements that make up a system or the number of different relationships between these elements or the number of different states of these relationships. For longer periods he consults his balance sheet, profit and loss statement, and such outside indicators as the prime rate of interest, manpower, growth of the economy.

Joël de Rosnay – Wikipedia

Then, in the appropriate computer language, one prepares the equations describing the interactions and connections between the different elements of the system.

It is a question of identifying nonvariants – that macrpscope, the general, structural, and functional principles- and rosnah able to apply them to one system as well as another.

The greatest weakness of these models is that they apparently cannot take into account the relationship between force and the conflicts that arise between the elements of every socioeconomic system.

When there are two forces present-two armies or two governments- we speak of the “balance of power. Negative controls, by regulating the divergences of positive loops, help to stabilize a system and enable it to last. They are the molecules of a cell, the inhabitants of a city, the personnel of an industrial firm and its machines, institutions, money, goods.

A NEW WORLD SCIENTIFIC SYSTEM

The owner of the account is “saving. Customers will not want to wait and will turn to a competitor. Youssef Ainane rated it it was amazing Jun 06, The paradoxical situation that confronts all those responsible for the maintenance and evolution of a complex system, whether the system be a state, a large organization, or an industry, can be expressed in the simple question, How can a stable organization whose goal is to maintain itself and endure be able to change and evolve?

If the flow of investment is equal to the flow of depreciation, or if births equal deaths, a state of dynamic equilibrium is achieved-a stationary not static state called zero growth.

With Wiener’s help Rosenblueth set up small interdisciplinary teams to explore the no man’s land roxnay the established sciences. This persistence of form is dynamic stability. Here the laws of statistics readily apply, enabling one to understand the behavior of the multitude-of disorganized complexity. The reservoir of industrial capital factories, machines, vehicles, equipment is filled through investment and emptied through depreciation, obsolescence, and wear and tear on machines and equipment.

The overdraft exercises a regulatory role like that of inventories, a full backlog of orders, or other reserves: By virtue of the flow of energy through the system-and despite the accumulation of entropy in the environment-the entropy in an open.

In the first case there is exponential growth or decline; in the second there is maintenance of the equilibrium Fig.

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. The term was created by the American physiologist Walter Cannon in see page Numerous other points of comparison deserve to be mentioned. An organization must then be in a position to capture the germs of change and use them in its evolution-which obliges it to adopt a mode of functioning characterized by macrosvope renewal of structures and the mobility of men and ideas.

In three steps, each of about ten years, MIT was to go from the birth of cybernetics to the most critical issue, the debate on limits to growth. They are maintained, however, within very strict limits. The presentation is excessively dualist; it confines thought to an maroscope from which it seems difficult to escape.
