Anyone who transmits information to other people. A.LOTKA, taking up an idea also emitted by A.KORZYBSKI (1933, 1950), writes: "Man is the only animal who in any considerable measure bequeaths to his descendants the accumulated wisdom of past generations. Evolution in this case proceeds not merely by the slow process of selection , but is immensely hastened by the cumulative and continuous growth of a body of knowledge exempt from the law of mortality which sets a term on the life of the individual" (1956, p.379) To a greater or lesser degree, we are all communi-cators and it is mainly this function which shapes society. From the viewpoint of evolution , we could speak of a kind of collective lamarckian heredity of acquired mental characters. The existence of communicators in non-human systems has not be researched to any great extent, save in ethology.
Figure 1a. The Mandelbrot set illustrates self-similarity. As you zoom in on the image at finer and finer scales, the same pattern re-appears so that it is virtually impossible to know at which level you are looking. Figure 1b. Mandelbrot zoomed 6x Figure 1c.

Complex systems present problems in mathematical modelling . Complex systems is a new approach to science that studies how relationships between parts give rise to the collective behaviors of a system and how the system interacts and forms relationships with its environment. The equations from which complex system models are developed generally derive from statistical physics , information theory and non-linear dynamics , and represent organized but unpredictable behaviors of systems of nature that are considered fundamentally complex .

Morphological analysis (problem-solving)
Morphological Analysis or General Morphological Analysis is a method developed by Fritz Zwicky (1967, 1969) for exploring all the possible solutions to a multi-dimensional, non-quantified problem complex. [ 1 ] [ edit ] Overview General Morphology was developed by Fritz Zwicky , the Bulgarian-born, Swiss-national astrophysicist based at the California Institute of Technology .Network Science
Holism in science , or Holistic science , is an approach to research that emphasizes the study of complex systems . This practice is in contrast to a purely analytic tradition (sometimes called reductionism ) which aims to gain understanding of systems by dividing them into smaller composing elements and gaining understanding of the system through understanding their elemental properties. The holism-reductionism dichotomy is often evident in conflicting interpretations of experimental findings and in setting priorities for future research.

Gerald Midgley
Systems thinking, complexity and the philosophy of science (2008) Midgley, Gerald Having made the case for science as intervention, I will then return to the theme of systems thinking and complexity in order to argue specifically for systemic intervention.cross-posted from www.emergentbydesign.com I've seen a bunch of posts bubble up over the past few days that are really sparking my curiousity about what is really going on with Twitter, so I need to do a little brain dump. Bear with me. Insight #1 An article by Rosabeth Moss Kanter was just published today on the Harvard Business Review website, titled On Twitter and in the Workplace, It's Power to the Connectors . In it, she highlights the fact that there is an organizational trend moving away from the hierarchical networks of the 20th century, and towards complex, distributed, non-hierarchical structures of business organization and leadership.
Is Twitter a Complex Adaptive System?
Intelligent Complex Adaptive Systems
I don’t believe in the existence of a complex systems theory as such and, so far, I’m still referring to complex systems science (CSS) in order to describe my research endeavours. In my view, the latter is constituted, up until now, by a bundle of loosely connected methods and theories aiming to observe— from contrasted standpoints—these fascinating objects of research called complex adaptive systems. Nearly 40 years after Von Bertalanffy’s General System Theory (1968) and Jacques Monod’s Chance and Necessity (1971), it is fair to look back and to try to assess how much remains to be said about these complex adaptive systems. After all, Prigogine’s Order out of Chaos (1984) already demonstrated that future wasn’t entirely predictable in a history- contingent world.Observability of complex systems

Complex systems made simple
Simplexity is an emerging theory that proposes a possible complementary relationship between complexity and simplicity . The term draws from General Systems Theory , Dialectics (philosophy) and Design . Jeffrey Kluger wrote a book about this phenomenon that describes how house plants can be more complicated than industrial plants, how a truck driver's job can be as difficult as a CEO's and why 90% of the money donated to help cure diseases are given only to the research of 10% of them (and vice versa). The term has been adopted in advertising , and marketing and other industries. [ edit ] Design aspects Complexity tends to rise as system elements specialize and diversify to solve specific challenges.
