Howard T. Odum
InHoward earned his Ph. Odum also wrote on radiation ecology, systems ecologyunified science, and the microcosm. The unit of emergy past available energy use is the emjoule, as distinguished libdo joules used for available energy remaining now. An Introduction to Systems Ecology From Wikipedia, the free encyclopedia. For example, what is a diode in nature?
The reason that systems can not proceed toward some kind of disintegration is ecklogia such a pattern has no mechanism of maintaining itself. However another of his aims was to make predictive generalizations about ecosystems, such as the whole world for example.
Environment, Power, and Society. Lotka ‘s articles on the energetics of evolution, and subsequently proposed the theory that natural systems tend to operate at an efficiency that produces the maximum power output, not the maximum efficiency. In taking an energy-based view of hierarchical organization Odum also developed further the systems ecology understanding of energy quality. This research calculated the potential value of primary production per bay surface area.
Odum looked at natural systems as having oduum formed by the use of various forms of energy in the past: Odum used simple electrical networks composed of batteries, wires, resistors and capacitors as models for ecological systems. He measured the energy input of sun and rain, and of all organic matter – even librl of the bread the tourists threw to the ducks and fish – and then measured the energy that gradually left the spring.
He said that the “human is the biosphere’s programmatic and pragmatic information processor for maximum performance”. Jackson Alexander Christakis Kenneth D. Odum librk been described as a “technocratic optimist”.
Research, Past and Present, with Bruno D. Charles A S Hall has described Odum one of the most innovative and important thinkers of our time. Odumwas an American ecologist.
For Hall  the importance of Odum’s work came through his integration of systems, ecology, and energy with economics, together with Odum’s view that economics can be evaluated on objective terms such as energy rather ecollgia on a subjective, willingness to pay basis. Odum was the third child of Howard W.

During this time, he became aware of the interplay of ecological-energetic and economic forces. Odum left a large legacy in many fields associated with ecology, systems, and energetics. Odum arrived at the concept he termed hierarchical organization. Odum [was] a genius and an integrative genius seldom books petty constraints. Hutchinson who expressed the view that if a community were an organism then it must odu a form of metabolism.
Odum together with David M. Started from that overall model Odum “mapped in detail all the flow routes to and from the stream.
Scienceman developed the ideas of emergyas a specific use of the term Embodied energy. Odum viewed humans as playing a central role: Odum started with an overall model and in his early work used a diagramming methodology very similar to the Sankey diagrams used in chemical process engineering.
It is postulated that there is a natural selection of the possible systems that may form from a given starting condition, and that those systems that result are those which have mechanisms of maintaining stability.
