Sustainability and Its Evaluation The first and second laws account for billions of observations that describe a tendency in time, a time arrow: Next we show that the planetary circulations and the main global climate zones may also be anticipated based on the same principle.

Its predictions of speed and stroke frequency are the same as those for running on deformable ground, and they agree with much data Fig. Despite all these differences, numerous investigators have found that there are strong dynamixs in certain functional characteristics of runners, swimmers, and fliers. Thus, even though some animals do not touch the ground, they use the ground to propel themselves.

Heat Mass Transfer 44, — The sawtooth pattern results because flying velocity V is composed of alternating work done to overcome vertical loss W1 and work done to overcome horizontal loss W2.

In place of Eq. Science cojstructal our knowledge of how nature works. We write a temperature drop expression of type 3. In constructal theory, we have studied the effect of superimposing loops on our dendritic fluid networks Wechsatol et al. A clear application of these concepts is in operations research and manufacturing, where the invention of the first auto assembly line is analogous to the appearance of the first street Carone ; Carone et al.


The pipe wall thickness is neglected for the sake of simplicity. The most special and, potentially, most lasting contribution of this new theory is that it explains the origin of huge volumes of observations in fields far removed from that of the theory and its authors. For simplicity, we ignored elastic storage during landing. At first sight, these figures show an expected trend: The farmer and the hunter would walk straight to the point farm, village, river where the market was located.

The extraordinary growth of Argentina was a by-product of the rapid industrialization of Europe and North America, which created an unprecedented demand for beef, grains, and wool.

If it is granted that people are not like drops of water, why would there be by any reason to think that social networks construdtal resemble river networks or trees? Similarly, the constructal law proclaims the existence of a concept: This design principle can be seen, for example, dynamocs the tree-shaped flows of river basins, lung structure or the cracking pattern of drying mud flats, in the tube shape of pipes, or in the height versus depth proportionality in the cross sections of rivers.

Good ideas travel and persist. The reason why running is no different from swimming or flying in spite of the fact that swimmers and fliers do not touch the ground is that the ground supports the weight and feels the movement of every body that exists above it.


Italian and French migrants provided the necessary dynamicss force both in the countryside and in the cities. In fact, during reconstruction, big ways were opened for people and goods transportation from the Lisbon harbor to the city center. Recognition of the continuum requires a study of the theor spaces between the tree links. The River Basins Case Flow architectures are everywhere in nature, from the planetary circulation to the smallest scales.

Constructal Theory of Social Dynamics

A Family of Social Potentials The modern problem, then, is one of bringing the street near a small but finite-size group of inhabitants; this group would first have to walk to reach the street. In that case, we know the forces that drive the movement. How to Distribute Hot Water over an Area The distribution of hot water to users dynamicd a specified territory presents two problems to the thermal designer: Schools of fish are beautiful because they display precise patterns of organization.

The railroads were financed not by direct foreign investment, but by the floating of bonds on the London market. The contribution of constructal theory is that the performance and the main geometric cpnstructal mechanism, structure of the organized system can be predicted in purely deterministic fashion.
