A scientist at Duke University says the natural evolution of social organizations into larger and more complex communities that exhibit distinct hierarchies can be predicted from the same law of physics that gives rise to tree branches and river deltas.

In a paper published June 15 in the International Journal of Energy Research, Adrian Bejan outlines how these seemingly disparate phenomena are actually connected through the of evolution in nature. Penned by Bejan in 1996, the law states that for a system to survive, it must evolve over time to increase its access to flow.

The human vascular system, for example, has evolved to provide blood flow through a network of a few large arteries and many small capillaries. River systems, tree branches, and modern highway and road networks show the same principle at work. Bejan has used these insights to predict the natural evolution and design of socioeconomic systems, the vast array of object sizes found throughout the universe, and the modern airplane, among many others.

With his newest paper, Bejan adds to the list the tendency for living organisms—most notably humans—to organize themselves into increasingly large and complex societies to have access to and make better use of finite resources. He also introduces the concept that innovation is nothing more than an idea that liberates flow locally, and increases all of society's access to resources.

"Because of economies of scale, it is more efficient to move items en masse rather than as individual units," said Bejan, the J.A. Jones Professor of Mechanical Engineering at Duke. "And because resources are moved over an area on the surface of the Earth, long distribution lines are needed to move large quantities of resources."

In this paper, Bejan uses the commodity of to illustrate his meaning. When human society was nothing more than a collection of huts, each building might have had its own fire to heat water. It would be much more efficient, however, to have a single fire located in the center of the community that could serve them all equally well.

This simple setup would soon become inefficient. As communities grew, those living on the fringes would either have to walk further to get hot water or build longer pipes, leading to wasted energy and .

The solution is to replace this simple radial design using only direct connections with a tree-shaped or "dendritic" distribution architecture. Such a structure reduces heat loss as the water is transported and requires less power to pump it.

Bejan uses a handful of simple designs featuring both architectures to show that the dendritic distribution solution is more efficient than the simpler setup. The result is an effort to show why humans naturally organize themselves into societies and why so many of the resulting distribution systems become hierarchical as their size and complexity increase.

"Water systems typically have one large treatment plant with several pumping stations moving from larger to smaller pipes before finally reaching individual homes," explained Bejan. "Electricity is similar with few power plants and many strategically placed transformer stations. Even information has taken this form with a few large data centers serving several tiered steps of distribution before reaching your smartphone. And the reason these all have a similar hierarchical architecture lies within constructal law of evolution everywhere."

Bejan finishes his paper by arguing that the true nature of an innovation is simply a local design change that increases the efficiency of the distribution of a resource to the entire population. While the individual innovator may benefit greatly from the idea, the entire community also gains better access to that resource, which serves to reduce overall inequality.

"The effect of innovation on controlling inequality is an argument for spreading education, know-how, and the spirit to question and take risks," said Bejan. "These are the essential tools needed for generating innovation in areas of the world not traditionally known for it."

try sorting on a basic truth matrix; biggest driver those act n greed, sort them; oh, that's the same thang; now when you gotta define a set with a truth value of an object that doesn't exist; juz sort by flow

We are also evolving our social relationships in other macroeconomics ways. My book shows how to understand what is going on. Write to me at chesterdh@hotmail.com for an e-copy of 310 page "Consequential Macroeconomics" and enter in depth into the true science of our social system.

"Logic is a Mind trap, that can drive you into an endless maze of deadends."

I'm not sure? Frank Herbert perhaps? Paraphrased? I suppose that would be a logical deduction...

The author seems not to have much regard for rugged individualism and the need for aloneness, which is not the same as being lonely. Social interaction between like-minded individuals and groups has its merits, but too much socialisation will eventually take its toll on those in any community or tribe who are or become less enthralled with the planners/leaders of the group/community, for whatever reason...usually political, religious, socioeconomic, or they realise that something better lies elsewhere.
I recall that a certain "community organizer" attempted the "groupthink" of Socialist ideology and did manage to convince a percentage of the population to accept his Socialist ideals. But all others would have none of it, mainly due to their sense of right and wrong.

"The effect of innovation on controlling inequality is an argument for spreading education, know-how, and the spirit to question and take risks," said Bejan. "These are the essential tools needed for generating innovation in areas of the world not traditionally known for it."

I am assuming that he refers to third-world nations such as in Africa, Central America and elsewhere. Such countries are mostly ruled by corrupt tyrants who don't care much for their constituents or improving their lot in life. The U.S. gov cannot change them by any means except for charitable contributions and volunteer work by caring individuals. As far as education, one must have a strong desire to become educated in order to better oneself. Not everyone has a strong desire to be schooled formally. At some point they will complain about unequal treatment by society because they aren't educated enough for the job they want. Whose fault is it? They blame society instead of themselves.

this from one living among vast nonsense; not, the result of logic of the logical; a discussion of idiocy, attributes, etc
