If this postulate is applied to all of nature, the resulting proposition is that nature is as a whole in a steady state or is in the most stable form possible and constitutes one big entity.

Le Chatelier’s principle from this view point may be phrased that a system with a self correcting mechanism has reached this condition by natural selection.

Odum said that “when a group gathers around ecologi table to talk about analyzing the main components of a new system or problem, one person can diagram for the group, enhancing the coherence of the discussion.

Circuit diagrams were skillfully used to illustrate the dependence of agricultural ecosystems and industrial societies upon fossil fuel subsidies He therefore funded the research into the use of conventional economic approaches to quantify dollar values of ecological resources for recreational, treatment and other uses.

In this simulation, Odum attempted to derive an ecological analog for electrical voltage.

However another of his aims was to make predictive generalizations about ecosystems, such as the whole world for example. This does not necessarily contradict evolutionary changes in the earth’s history since these changes re be part of a larger steady state systems. Moreover, at the time of writing his thesis, Odum felt that the principle of natural selection was more than empiricalbecause it had a teleological, that is a “stability over time” component.

Kitching claimed that the language was a direct result of working with analogue computers, and reflected an electrical engineer’s approach to the problem of system representation: This page was last edited on 16 Novemberat This extension relied on the definition of an entity as a combination of properties that have some stability with time. Eoclogia reason that systems can not proceed toward some kind of disintegration oudm that such a pattern has no mechanism of maintaining itself.
