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.

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?

Customers will not want macrscope wait and will turn to a competitor. Examples abound in ecology.

Out of this new friendship would be born, twenty years later, cybernetics. In a negative loop every variation toward a plus triggers a correction toward the minus, and vice versa. Ecological, biological, and social systems are homeostatic. Unknown Bindingpages. Equations corresponding to various state and flow variables can be programmed on a computer in order to verify the validity of certain hypotheses: Simulation considers the dynamic behavior of a macrosclpe system.

In the management of the family budget one can choose a high style of living living beyond one’s meanswith the constraints that it implies with respect to banks and creditors. The analytic approach seeks to reduce a system to its elementary elements in order to study in detail and understand the types of interaction that exist between them.

The Macroscope: Chap. 2

macroscopd The correction of the body’s equilibrium when we stand is accomplished by the contraction of certain muscles without our having rsnay think about it even when the brain intervenes. By modifying one variable at a time, it tries to infer general laws that will enable one to predict the properties of a system under very different conditions. Variety and mobility enable it to adapt to change.


The coexistence of the two modes at the heart of an open system, constantly subject to random disturbances from its environment, creates a series of common behavior patterns. The user can change the initial conditions “just to see what will happen. T can be changed to-T without modifying the phenomena under study.

A homeostatic ultrastable system can macrosxope only if it is assaulted by events from the world outside. Pushed too soon, it leads to an homogenizing and paralyzing mixture; pushed too late, it leads to the confrontation of individualism and mzcroscope perhaps a disassociation still greater than what had formerly existed. Two major variables measure world growth: In the same way the leader of an organization must help his own system to distribute its operating energy.

In effect all rigidity, sclerosis, and perpetuity of structures or hierarchy is clearly macrosscope to a system that allows evolution see notes. In fact the juxtaposition demonstrates that the structures or the functions of an open system remain identical to themselves in spite of the continuous turnover of the components of the system. Once again we are encumbered with the danger of dogmatism.

The Macroscope: A New World Scientific System

Theoretically, however, it allows a more rapid increase in the standard of living. The balance sheet applies to one date only, say December Negative feedback leads to adaptive, or goal-seeking behavior: Another example of a nonlinear relationship is the response of enzymes to different concentrations of substrate molecules that they transform. In some areas intensive agriculture destroys the equilibrium of the rpsnay pyramid and replaces it with an unstable equilibrium macrodcope only three stages grain, cattle, and man controlled by a single dominant species.


Thus we need new tools with which to approach organized complexity, interdependence, and regulation.

Joseph Lamarre rated it really liked it Dec 09, Confronted with complexity and interdependence, we all use simple analogical models. The analytic and the systemic approaches are more complementary than opposed, yet neither one is reducible to the other. The goal of these modifications is to maintain the internal balances.


Valves that control the volume of various flows. At the same time it bestows on the systems very special properties. The crystal-like organization evolves slowly in the give and take of radical and traumatic reforms.

Consider two examples related to inventory and cash management. As for molecules, cells, macrlscope microbes, they will never complain of their condition!

Simulation appears to be one of the most resourceful tools rosnqy the systemic approach. Living systems can adapt, within certain limits, to sudden modifications coming from the outside world. Such servomechanisms are able to predict the trajectory of an airplane by taking into account the elements of past trajectories. Carl Danneels rated it it was amazing May 26, The limits are well known. It can be adapted, modified, and modeled permanently by often imperceptible readjustments, depending on disturbances or circumstances.

The former type is still found in most computers today. His object was to regard all industries as cybernetics systems in order to simulate and to try to predict their behavior.

The reverse situation is that of strong demand.
