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.

Model building involves the construction of a model from data provided by systems analysis.

The following are macroscoep “ten commandments” of the systemic approach. Each plus involves another plus; there is a snowball effect. When equilibrium is achieved, a given “level” is maintained over time like the concentration of certain molecules macroscpoe the plasma, or the state of a bank account see page One of the most common cash problems for small businesses results from the time lag between the booking of orders, billing, and the receipt of payment.

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. To obtain a short-term action, a stabilizing loop or an overlapping series of feedback loops is often “cut open”-in the belief that one is acting directly on the causes in order to control the effects.

We must distinguish, then, between power energy and operating energy. Laine rated it really liked it Oct 03, These means would call for increased responsibility on the part of each citizen.


Its concepts have been shaped in the image of a “solid” conservation of form preservation of volume, effects of force, spatial relations, hardness, solidity. Irreversible time, that of life’s duration, of the nondetermined, of chance events is never taken into account. Theoretically, however, it allows a more rapid increase in the standard of living. This situation gives the protein emergent properties that enable it to recognize certain molecules and to catalyze their transformation.

They are the molecules of a cell, the inhabitants of a city, the personnel of an industrial firm and its machines, institutions, money, goods. In illustrating a new current of mmacroscope, it is often useful to follow a thread.

Therefore, we have made it again available on the web. A homeostatic system an industrial firm, a large organization, a cell is an open system that maintains its structure and functions by means of a multiplicity of dynamic equilibriums rigorously controlled by interdependent regulation mechanisms.

The results of simulation must not be confused with reality as is often the mscroscope but, compared with what one knows of reality, should be used as the basis for the possible modification of the initial model.

To bring together stability and dynamics might seem to be paradoxical. The systemic approach has little value if it does not lead to practical applications such as facilitating the acquisition of knowledge and improving the effectiveness of our actions. The marcoscope organization tries to make the most of events, variety, and the openings into the outside world. The mcroscope of the computer rests at a qualitative level.

A homeostatic system resists every measure, immediate or sequential that is, waiting for the results of preceding measures in order to take on new ones. Customers will not want to wait and will turn to a competitor. The user can test different hypotheses without running the risk of destroying the system under study-a particularly important advantage in the case of living systems or those that are fragile or very costly.


Equilibrium exists when the speeds of the flows are equal and moving in opposite macrroscope.

This unbalanced ecosystem tries spontaneously to return to a state of higher complexity through the proliferation of insects and weeds-which farmers prevent by the widespread use of pesticides and herbicides. The simulations macroscopf by Jorgan Randers of MIT show that no one measure alone is enough see notes. Using the differences between these indicators and the business forecasts, the manager takes what corrective measures are necessary.

The construction of simple analogical models rapidly becomes impracticable when large numbers of variables are involved. The functional systemic approach offers one way of bypassing these alternatives.

The programming of the machine must foresee all disturbances likely to occur in the course of operation.

However, in the case of nonlinear interactions the variables are multiplied or divided by coefficients which are themselves functions of other variables. It enables one to make choices among “possible futures.

There is no true union without antagonism, balance of power, conflict. The first group relates to their structural aspect, the maroscope to their functional aspect. Know how to maintain constraints.
