A Pattern Language Explained. Christopher Alexander is famous for his book on architecture, A Pattern Language.

A Pattern Language Explained

What is not so well known is that Alexander has spent at least as much of his life in building as in writing, and he and his colleagues have produced some 300 buildings as well as gardens, neighborhoods and rural landscapes. Alexander’s career now spans over half a century, with written works that are acknowledged landmarks of design theory.

His first book in 1964, Notes on the Synthesis of Form, was widely celebrated at the time; one review by Industrial Design magazine hailed it as, “one of the most important contemporary books about the art of design, what it is, and how to go about it”. His later work has also had a remarkable influence in software, open source computing, sociology, biology and other diverse disciplines. The software for smart phones, most computer games and many other applications is built on ‘pattern languages of programming’, also called ‘design patterns’. Unintended Consequences. General System Theory. Disciplines, and proposed a different approach to and organization of knowledge.

General System Theory

This goal of developing anew worldview was largely lost in the initial applications of GST, which were grounded in a moremechanistic, instrumental perspective, and seemed to promise the ability to control and predict moreaccurately and efficiently.GST has not proved to be the single unifying breakthrough approach that von Bertalanffy envisioned. Insome circles, GST is still viewed with suspicion as fundamentally scientistic. Complexity Rising: From Human Beings to Human Civilization, a Complexity Profile. Since time immemorial humans have complained that life is becoming more complex, but it is only now that we have a hope to analyze formally and verify this lament.

Complexity Rising: From Human Beings to Human Civilization, a Complexity Profile

This article analyzes the human social environment using the "complexity profile," a mathematical tool for characterizing the collective behavior of a system.

Emergence: the remarkable simplicity of complexity. From the fractal patterns of snowflakes to cellular lifeforms, our universe is full of complex phenomena – but how does this complexity arise?

Emergence: the remarkable simplicity of complexity

“Emergence” describes the ability of individual components of a large system to work together to give rise to dramatic and diverse behaviour. Recent work by Enkeleida Lushi and colleagues from Brown University showed how bacteria in a drop of water spontaneously form a bi-directional vortex, with the bacteria near the centre of the droplet circulating in the opposite direction to those near the edge. Since the bacteria do not consciously decide to create the bi-directional vortex, such behaviour is said to be “emergent”. Unlike music from an orchestra led by the conductor, emergent behaviour arises spontaneously due to (often simple) interactions of the constituent parts with each other and the surrounding environment. Here, there is no “leader” deciding on the behaviour of the system. Click to enlarge Emergence all around us Consider an ant colony. Untitled - Comp.Econ.SFI.pdf. Comp.Econ.SFI.pdf. Edgar Morin's Path of Complexity.

Edgar Morin has been urging for a shift towards complexity thinking for many decades.

Edgar Morin's Path of Complexity

He has aunique capability to move between the natural and social sciences—without doing either of themany injustice—and is ideally placed to address the epistemological, ethical and practical problemsof our times. What makes Morin unique amongst complexity theorists is the way in which heturns a critical eye on complexity theory itself, resisting a return to determinism, reduction anddisjunction in come approaches to complexity.In this extremely valuable volume of translated essays he turns his attention to the technicaland philosophical underpinnings of complexity theory and applies it to a wide-ranging numberofissues including the nature of scientific thinking, self-organisation, action theory, the notion of the subject, education, the idea of solidarity and the idea of the “enterprise.”

W. Ross Ashby, Cybernetics and Requisite Variety (1956)

Cybernetics was defined by Wiener as "the science of control and communication, in the animal and the machine" - in a word, as the art of steermanship. Co-ordination, regulation and control will be its themes, for these are of the greatest biological and practical interests. 1/2. Cybernetics deals with all forms of behaviour in so far as they are regular, or determinate, or reproducible. 1/3. 1/6.

One is that it offers a single vocabulary and a single set of concepts suitable for representing the most diverse types of systems. It has been found repeatedly in science that the discovery that two branches are related leads to each branch helping in the development of the other. 1/7. In the simpler systems, the methods of cybernetics sometimes show no obvious advantage over those that have long been known.
