Wealth inequality

The physics basis

This article unifies physics with economics by showing that the distribution of wealth is related proportionally to the movement of all the streams of a live society. The ‘unequal’ distribution of wealth on the earth happens naturally. Hierarchy is unavoidable, with staying power, and difficult to efface.

Two architectures illustrate this idea: river basins and the movement of freight.

The nonuniform distribution of wealth becomes more accentuated as the economy becomes more developed, i.e., as its flow architecture becomes more complex for the purpose of covering smaller and smaller interstices of the overall (fixed) territory.

This theory also predicts the Lorenz-type distribution of income inequality, which was adopted empirically for a century.



Evolution as Physics: The Human & Machine Species

Biomimetism and Constructal lawThis article from Adrian Bejan and published by European Review shows that humans and technology are one species, and not two: humans and their artefacts are evolving as one species, the ‘human & machine species’.

The evolution of the human & machine species is well illustrated by the evolution of the commercial aircraft, the cooling of electronics, and modern athletics.

These evolutionary forms of flow organization can be predicted based on the law of physics that governs evolution in nature, bio and non-bio: the constructal law.

In brief, evolution, life and the human & machine species are physics

Evolution and the City

Le Pirée “A lot of care and attention is payed to urban planning, but the evolution of human settlements happens naturally because it is governed by a law of Physics.”

The evolution of the City is discussed by professor Adrian Bejan in the February 2017 issue of the Mechanical Engineering magazine.







Donald Trump victory predicted in July, 2016 – thanks to the Constructal Law

Trump victory predicted by A. Bejan in July 2016On 25 July 2016, in an interview by the GEC MOOC team, Professor Adrian Bejan predicted that Donald Trump would win the US Presidential Election on 8 November 2016, on the basis of the S-curve theory of the Constructal Law in physics, as showed in the Figure 8.1, page 157, in his book The Physics of Life.


The Physics of Life: a review

S03605442 An in-depth analysis and a detailed review  of every chapters of Adrian’s Bejan last book , “The Physics of Life: The Evolution of Everything“, is provided by M. M. Awad in this article, published in the Energy journal:

“This book is an invitation to think and to have fun with ideas. Adrian Bejan concludes that the constructal law “is bound to evolve, to serve our thinking better”. My own conclusion is that readers of this book are able to see the world more clearly, and to predict its future better and with greater confidence.” – M. M. Awad

Sitting around the (constructal) campfire

In this article, Brian Resnick quote Prof. Adrian Bejan in order to provide us with some good advices on building a successful pyre, and discusses the processes tooking place while sitting around the campfire.

In a study published in 2015 in one of the Nature Scientific Reports,  Professor Adrian Bejan, effectively showed that the best fires share the same design pattern: they are roughly as tall as they are wide.
