Why does a railway network look like a river? Why do the streets of old Rome look like a leaf? Because whether their shape is determined by the interactions of molecules or the choices made by individual humans, all of these systems of flow are governed by a relatively simple new principle of thermodynamics. Consequently, these repeating patterns are no accident. First described a decade ago by Bejan, a professor of mechanical engineering at Duke, the constructal theory is a deceptively simple explanation for why these branching patterns occur so frequently: for a flow system to persist in time, its configuration must change such that it provides easier access to its currents.

Simply put, if something is flowing, it will branch in a fairly predictable pattern to reduce imperfections like friction, or in this case, bumping into pedestrians coming the other way. We see the resulting branching pattern at all scales, from the alveoli of the lungs, to the paths animals take to a watering hole, to the streams of a great river delta. Each of these structures has been honed by time to handle flow as efficiently as possible. Social scientists who are applying the theory to their fields suddenly see constructal patterns in everything from human migration patterns to a bowl of boiling rigatoni.

For example, Bejan is currently branching out, as it were, on how constructal theory applies to the running, flying and swimming of animals and the distribution of city sizes -- a few large, many small -- all over the world. The page text features 18 essays by an international group of social scientists exploring the constructal underpinnings of everything from urban development and racial segregation to the development of written language.

Adrian Bejan - Constructal Law

About these proceedings Introduction Constructal Theory of Social Dynamics brings together for the first time social scientists and engineers to develop a predictive theory of social organization, as a conglomerate of mating flows that morph in time to flow more easily people, goods, money, energy, information. These flows have objectives e. The result is organization flow architecture derived from one principle of configuration evolution in time the constructal law : "for a flow system to persist in time, its configuration must morph such that it provides easier access to its streams. In the social sciences, there is substantial literature based on the use of optima to deduce social, population and economic dynamics. The constructal approach of this book links social sciences with physics, biology and engineering. The book explores the deterministic principle that generates a broad array of patterned phenomena, in demography, geography, communications, hierarchy, and multiple scales.
