The dynamic behavior of every system, regardless of its complexity, depends in the last analysis on two kinds of variables: It used-for the first time-a superfast magnetic memory invented by a young electronics engineer from the servomechanisms laboratory, Jay W.

One major factor is the scientific community’s overwhelming preference for process logic over spatial logic.

The Macroscope: Chap. 2

I immediately saw it as the key to a mystery that had puzzled me since boyhood. 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. Walter Pitts became one of Wiener’s disciples and contributed to the exchange of ideas between Wiener and McCulloch; it was he who succeeded in convincing McCulloch to install himself at MIT in with his entire team of physiologists.

Third, years later, reading a science magazine, I ran across a forthright statement that sea level had risen feet over the past 20, years. They are the molecules of a cell, the inhabitants of a city, the personnel of an industrial firm and its machines, institutions, money, goods.

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. There are no discussion topics on this book yet. When the input flow is greater than the output flow, money accumulates in the account. 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.


Thus Wiener and Bigelow discovered the closed loop of information necessary to correct any action-the negative feedback loop-and they generalized this discovery in terms of the human organism. Justin Millette rated it liked it Aug 18, First, we, its stewards, must decide what to do with this new instrument and what role we will play in the science that follows.

Open Preview See a Problem? This was the beginning of bionics and the research on artificial intelligence and robots. The fight against insects leads as well to the disappearance of the birds that feed on the insects; the result in the long term is that the insects return ,acroscope full force-but there are no birds.

The rewards will be invaluable for understanding the human and biophysical processes operating during the ice ages. Might there have been some factor, cultural or physical, that caused systematic differences between coastal and interior people?

In the same way the leader of an organization must help his own system to distribute its operating energy.

The Macroscope : A New World Scientific System

Cannon who gave homeostasis its name see page 43 and then at Harvard Medical School. The wild behavior of positive loops-a veritable death wish-must be controlled by negative loops.

Yet without being exhaustive the table has the advantage of effectively opposing the two complementary approaches, one of which-the analytic approach-has been favored disproportionately in our educational system.

Lists with This Book. Instead, we spent enormous efforts trying to get rid of the haze that was blocking our view of the ground but was, for the geophysicist, the key macrkscope a scientific breakthrough of historic proportions. Three examples will serve to explain the relationships between flow variables and state variables and will clarify several of the ways in which they act at the different levels of a complex system.


In the first chapter numerous examples were given: For action because the systemic approach provides rules for confronting complexity and because it assigns to their hierarchical order the elements that are the basis for decisions. Examples abound in ecology.

The maintenance of equilibrium requires tight control. Applied too easily, the systems concept is often used wildly in the most diverse areas: He mentions geography, but only as one of many disciplines that one learns ,acroscope school and that can be illuminated by posing great questions about how the world works.

A servomechanism distributes its own operating energy through the distribution of information that commands its operational parts. At the same time, those who by nature of their research have been accustomed to think in terms of flow, transfer, exchange, and irreversibility-biologists, economists, and ecologists-assimilate more naturally the systemic concepts and communicate more easily among themselves.

The best results came from a policy macroscops, a combination of measures used at the same time: The word cybernetics was reinvented by Norbert Wiener in from the Greek kubernetespilot, or rudder.

One establishes first a complete diagram of the causal relations between the elements of the subsystem. These basic rosna of cybernetics apply to every human organization.
