Description: Homeostasis: a framework for integrating the life sciences..
“Nurse education curricula continue to emphasize the holistic nature of health and ill-health. As a concept, holism recognizes that the interactions between a person and his/her environment are significant factors in shaping the individual, and important determinants of wellbeing. Psychosocial interactions as a basis for health now figure prominently in nursing curricula. In contrast, the applied biological sciences have increasingly become marginalized, yet knowledge of the biological construct of the individual, and an understanding of how it is influenced by psychosocial interactions, are also necessary if holistic care is the aim. Nursing models attempt to reinforce holistic principles, but the integrative nature of health and illness needs to be established before their application. This article proposes that the concept of homeostasis, and its relationship to systems theory, provides a workable framework for teaching the basis of health, and so forms a foundation for the application of nursing theory and nursing models.”

Description: Explains how landscape design and management, while accommodating human use, should aim not to tip a healthy landscape out of its homeostatic equilibrium, not to restrict the operation of natural homeostatic adjustment mechanisms, and, when necessary, actively to support the landscape in its effort to seek equilibrium in response to stress.
“The behaviours of two aspects of landscapes, biotic communities and watershed morphology, show that landscapes are homeostatic systems exhibiting conditions of health and disease. In a biotic community, a state of homeostatic balance is represented by the climax community, maintaining itself in a condition of dynamic equilibrium. In a stream system, a condition of dynamic equilibrium is represented by discharges of water and sediment equal to inflows to the system. Each aspect of a landscape, when disturbed, undergoes succession, morphologic adjustments and other processes to re-establish equilibrium.”

Description: Harmony reigns through all levels of the Ecosphere-Harmony is the sum of the laws of nature.
“Harmony - Function 18 Harmony is the ultimate function of biodiversity: the consequence of the 17 functions already described. Harmony in nature is diverse, pervasive and persistent, existing at all levels necessary to the maintenance of the whole. Harmony emerged slowly in both aquatic and terrestrial ecosystems. We can observe harmony in many aspects of the Ecosphere: animal and plant form (trees, flowers, birds, fish, insects), the obvious grace of animal movement (swimming, flight, running); colours of birds, fish, insects, trees, leaves, flowers; radial or bilateral symmetries of individual animals and flowers. Even the world of microorganisms is full of harmonies of many types. Another aspect of harmony is the innate capacity for hundreds and indeed thousands of life forms to live together "in relative harmony" within a community or larger ecosystem, and to form linkages, co-adaptations, and symbioses. The developmental and physiological harmonies that have evolved within individual organisms is another level of harmony. Wholeness, completeness, health, and integrity are the broader aspects of the innate harmony function in the Ecosphere.Harmony cannot be separated from the abiotic part of biodiversity: the matrix of rivers, lakes, waterfalls, wind, pounding of oceanic surf, landforms, clouds, and all other "abiotic" conditions (within which organisms and ecosystems evolved and apart from which they cannot survive). Indeed, since the beginning of life, organisms have dramatically changed and shaped the characteristics of the Ecosphere. Harmonies appear to be the ultimate consequence of the workings of the laws of nature. The deeper origins of the pervasive persistence of harmonies in nature may be due to an innate drive of organisms to achieve maximum "self-realization" during the course of their lifetime, a concept described by a number of authors, including Arne Naess, Stuart Kaufmann, Edward Goldsmith and Holmes Rolston,III.”

Description: altruistic behavior in nature
"Mutual grooming plays an important part in the social life of chimpanzees, and two friends, or even a small group, will sit quietly for hours searching through each other's long black hair for specks of dirt, grass seeds, or ticks.Some students of animal behavior see in this grooming activity the first beginnings of true social and altruistic behavior in the whole animal kingdom."

Wikipedia - Mean Field Theory
Field of reference: Physics
Description: Multi-particle physical systems are so complex that only a very efficient approximate treatment is possible. The mean free theory describes such physical systems as individual particles evolving under the influence of an effective force, which is the combined force exerted by the rest of the system.
"Mean field theory (MFT, also known as self-consistent field theory) is a method to analyse physical systems with multiple bodies. A many-body system with interactions is generally very difficult to solve exactly, except for extremely simple cases (random field theory, 1D Ising model). The n-body system is replaced by a 1-body problem with a chosen good external field. The external field replaces the interaction of all the other particles to an arbitrary particle."
