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 dynamics of systems shatters the static vision of organizations and structures; by integrating time it makes manifest relatedness and development.
Gauthier Stricker rated it really liked it Jan 03, Complex systems integrate time into their organization. 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.
Published January 1st by HarperCollins Publishers. Two factors are important: Equations corresponding to various state and flow variables can be programmed on a computer in order to verify the validity of certain hypotheses: Prefer objectives to detailed programming. The balance sheet contains a variety of state variables: This makes it possible for an open system to adapt and respond to the great variety of modifications in the environment.
This is the case of exponential growth the quantity plotted on the vertical axis doubles by unit of time or of an S curve rapid growth following stabilization Fig. A thermostat or a water tank equipped with a float are simple examples of regulation by negative feedback Fig.
Causality becomes circular and opens up to finality. In concluding this introduction to the concept of system, we need to locate the systemic approach with respect to other approaches with which it is often confused. Time and Evolution 1. A more philosophical definition, suggested by Louis Couffignal inconsiders cybernetics as ” the art of assuring efficiency of action ” see notes. In the Malthusian model on page 77 these include the influences of birth rate on population and food rationing on mortality.
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. It is found in the cell, in the living organism, in the flame of a candle. It is not a new concept, what is new is the integration of the disciplines that has come about around it.
The Macroscope: A New World Scientific System
It is an instant picture of the situation of the company rosmay that single moment in time. Variety, however, is one of the conditions for the stability of a system.
There are definitions of the word system other than that given at the beginning of this chapter.
The inputs are the result of the environment’s influence on the system, and the outputs are the influence of the system on the environment. The limits are well known.
The systemic approach depends on cybernetics and system theory. Information serves as a basis for making the decisions that move the flows which maintain reserves or raise and lower the levels of the reservoirs.
The same applies to a manager or to anyone in charge of a large organization. Roosnay example is the problem of solid wastes. It should enable us to extract from the properties and the behavior of complex systems some general rules for understanding systems better and acting on them.
The Macroscope: A New World Scientific System by Joël de Rosnay
In every feedback loop, as the name suggests, information about the result of a transformation or an action is sent back to the input of the system in the form of input data.
For numerous specialists it is only an empty notion: The crystal preserves its structure by means of the balance of forces that cancel out each other in every node of the crystalline network-and by redundancy, or repetition of patterns.
There is a qualitative leap; the crossing of a threshold; life, reflective thought, and collective consciousness. Out of this new friendship would be born, twenty years later, cybernetics. For the communication of knowledge because the systemic approach has a conceptual framework.
Knowing that one can experiment on a model of reality rather than on reality itself, one can influence the time variable by accelerating very slow phenomena social phenomena, for example or slowing down ultrafast phenomena the impact of a projectile on a surface. Delays that result from variations in the speed of circulation of the flows, in the time of storage in the reservoirs, or in the “friction” between elements of the system.
Once again we are encumbered with the danger of dogmatism. Yet no definition of macrodcope word system can be entirely satisfying; it is the conception of system that is fertile-if one measures its extent and its limits.
The demographic curve stabilizes in an S curve, typical of growth limited by an outside factor Fig. This book is an excellent, easy to read introduction to cybernetics and systems thinking, with applications to living organisms, the economy and the world as a whole.
Denis Henri rated it it was amazing Feb 22, Thomas rated it fosnay was amazing Mar 23, In either case a positive feedback loop left to itself can lead only to the destruction of the system, through explosion or through the blocking of all its functions. Yet its reach cannot be held to the precision of definitions; the concept of system is not readily confined.
A complex open system can function according to different modes of behavior. The goal of these modifications is to maintain the internal balances. Simulation tries to make a system live by simultaneously involving all its variables.
As head of the Lincoln Laboratory, Forrester was assigned by mzcroscope Air Force in to coordinate the implementation of an alert and defense system, the SAGE system, using radar and computers for the first time.
It is not to be considered a “science,” a “theory,” ronsay a “discipline,” but a new methodology that makes possible the collection and organization of accumulated knowledge in order to increase the efficiency of our actions.
