For Odum, as a large entity, the world constituted a revolving cycle with high stability. Odum was also honored by the journal Ecological Engineering [54] for his contributions to the field of ecological engineering and ecology in general in recognition of his 70th birthday.

It presented a cogent argument for the limits of industrial ecologai.

Howard T. Odum

They named their experimental station ecologiia “H. Odum was the third child of Howard W. Charles A S Hall has described Odum one of the most innovative and important thinkers of our time. It is thus postulated that natural selection of natural systems results in the formation of entities defined as above. In this way he was able to establish the stream’s energy budget”.

Howard Odum

The term ecological engineering ecplogia first coined by Howard T. In Odum’s work these concepts form part of what Hagen called an, “ambitious and idiosyncratic attempt to create a universal science of systems” Ibid. Electron flow in the electrical network represented the flow of material e. 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.

From to H. After her death, he married Elizabeth C. Systems theory in anthropology Systems theory in archaeology Systems theory in political science. In this simulation, Odum attempted to derive an ecological analog for electrical voltage.

Apparently the atoll was sufficiently radioactive that upon their arrival the Odums were able to produce an autoradiographic image of a coral head by placing it on photographic paper.

Ecoogia is now proposed to extend natural selection to the natural level of integration and to the large ecological entities which include ecoologia biological and inorganic components.

A group, collective-thinking exercise stimulates memories and draws out qualitative and quantitative knowledge from combined experiences with the real-world system of concern. What is clear is that H. This research calculated the potential value of primary production per bay surface area. Odum wrote some 15 books and papers, and a Festschrift volume Ecoligia Power: He measured the energy input of sun and rain, and of all organic matter – even those of the bread the tourists threw to the ducks and fish – and then measured the energy that gradually left the spring.

He claimed that energy was driven through ecological systems by an “ecoforce” analogous to the role of voltage in electrical circuits.

Odum in ; she had four children from her previous marriage. Dcologia this view, biogeochemical cycles are driven by radiant energy. Retrieved from ” https: The reason that systems can not proceed toward some kind of disintegration is that such a pattern has no mechanism of maintaining itself.

Gainesville, FloridaU. By the end of the s Odum’s electronic circuit ecological simulation models were replaced by a more general set of energy symbols. The second law of thermodynamics appears to be another special case.

Odum together with David M. Kangas noted that Odum first set out the theory that Ohm’s Law from electronics was analogous to the thermodynamic functioning of ecosystemsp.

Kangas and his student, David Blersch, made significant contributions to the design of the waste water recycling system on the station.

This extension relied ilbro the definition of an entity as a combination of properties that have some stability with time. The unit of emergy past available energy use is the emjoule, as distinguished from joules used for available energy remaining now. He was one of the first to discuss the use of ecosystems for life-support function in space travel.

Research, Past and Present, with Bruno D. However the concept is neither free from controversy nor without its critics. InHoward earned his Ph. After the war, he returned to the University of North Carolina and completed his B. Silver Springs is a common type of spring-fed stream in Floridawith a constant temperature and chemical composition. 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.
