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.

There are only three ways to reduce the flow of the generation of solid wastes by acting on the valve the flow variable: Know how to use operating energy. Goodreads helps you keep track of books you want to read. He is an associate of the Principia Cybernetica Project.

Joël de Rosnay

The properties and the behavior of a complex system are determined by its internal organization and its relations with its environment. At the very moment that man discovered the simplest elements of matter and life, he tried, with the help of the famous metaphors of the “clock,” the “machine,” the “living organism,” to understand better the interactions between these elements.

Each system has a response time characteristic of that system, by reason of the combined effects of feedback loops, delays at reservoirs, and the sluggishness of flows. Bill Bauzile rated it really liked it Feb 08, It amplifies the slightest variation; it increases the possibilities of choice, accentuates differentiation, and generates complexity by increasing the possibilities for interaction.

At the same time, it seeks factors of integration, catalytic elements for invention and imagination.

The limitations of our brain make it impossible for us to make a system “live” without the help of computers and macrowcope systems, so we turn to these mechanical and electronic means.

No one has set the level of the concentration of oxygen in the air, the average macroscpe of the earth, the composition of the oceans. The present example is of only limited interest because it is such a rudimentary model; in the presence of several hundred variables, however, the simulation presents and achieves, as we shall see, valuable results. The theory of probability the kinetic theory of gases, thermodynamics, and population statistics all rely on unreal, “ghostly” phenomena, on useful but ideal simplifications that are almost never found in nature.


The individuality, the unique character of each element is revealed in the organized totality. As Dennis Meadows observed, however, the only alternatives are “mental models” made from fragments of elements and intuitive thinking see notes. To make this prediction possible, the laws of the additivity of elementary properties must be invoked. It enables us to verify the effects of a large number of variables on the overall functioning of a system; it ranks the role of each variable in order of importance; it detects the points of amplification or inhibition through which we can influence the behavior of the system.

Reaching beyond single analogies, this circulation makes possible the discovery of what is common among the most varied systems. The state level variables indicate the accumulation of a given quantity in the course of time; they express the result of an integration. Certainly there has been a revolution in our way of thinking; what now are the practical uses to which we can put it?

Theirs appeared to be “intelligent” behavior because they dealt with “experience” the recording of past events and predictions of the future. Romain rated it it was amazing Jul 07, Cyrille rated it really liked it Jan 18, In the same way the uncontrolled use of analogies, homologies, and isomorphisms can result in interpretations that complicate rather than enlighten.

Consider some examples of what happens in the rupture of natural cycles. And so are an automobile, a computer, macrosfope a washing machine! Cannon who gave homeostasis its name see page 43 and then at Harvard Medical School.

This particular state is called a steady state ; it is very different from the static state represented by the level of water in a reservoir having no communication with the environment Fig.


The Macroscope: A New World Scientific System

Two groups of characteristic features make it possible to describe in a very general way the systems that can be observed in nature. One could assume that in effect wages were being paid and deposited daily. However, in the case of nonlinear interactions the variables are multiplied or divided by rosnxy which are themselves functions of other variables. Bahman Abbassi rated it it was amazing Aug 25, The functional systemic approach offers one way of bypassing these alternatives.

They are three of the most general concepts of the systemic approach, and they are the keys to the juxtaposition of very different areas from biology to management, from engineering to ecology.

Perhaps one macoscope the best ways of seeing the strength and the impact of the systemic approach is to follow its birth and development in the lives of men and institutions.

Every real integration is founded on a previous differentiation.

Despite the strengths of these analogical models, thought is dispersed in a maze of macroscooe each secluded one from another by communication-tight enclosures. The first group relates to their structural aspect, the second to their functional aspect. Power energy is represented by the electric line or the current that heats a resistance; or it may be the water pipe that carries water pressure to a given point.

It is not afraid of a passing disorganization-the most efficient condition for readaptation. In Figure 49 below this situation is expressed in curves that show the number of molecules transformed I in the presence of an inhibitor, 2 in the presence of an activator, and 3 according to the relative concentration of inhibitors and activators.

Systems analysis and simulation bring out the sensitive points of a complex system.
