Adrian Bejan named 2018 Franklin Institute Award laureate
[image error]The Franklin Institute have recognized accomplishments in science and technology since 1824, and awarded since then researchers such as Nikola Tesla, Thomas Edison, Pierre and Marie Curie, Albert Einstein, Stephen Hawking, Gordon Moore, among others.
This year, Prof. Adrian Bejan will be the recipient of the 2018 Benjamin Franklin Medal in Mechanical Engineering, for his work in this field, and thus especially for the development of Constructal Theory.
The Franklin Institute Awards Ceremony and Dinner will be held on Thursday, April 19, 2018.

Everything can be explained by physics – including income disparity
[image error] In this recent article from Quartz, Ephrat Livni briefly reviews the global framework of Constructal theory, and interviews Adrian Bejan, with a specific focus on the application of his theory to social sciences.

La loi Constructale et sa place dans la thermodynamique
[image error]This french article has been published by Techniques de l’Ingénieur, and was written by Sylvie Lorente and Adrian Bejan.
The authors define and present the Constructal law as the law of physics that accounts for the natural tendency of all flow systems (animate or inanimate) to evolve into configurations that offer progressively greater flow access over time.
This article shows what make the Constructal law a part of thermodynamics, and that the domains covered by this new law of Physics are broad, ranging from fluid flows to heat and mass transfer.

Physics describes how income inequality happens…
[image error] … but can it solve the problem ?
Jakky Kerubo interviews and discusses one of the last application of Constructal theory: explaining how income inequality happens… But this explanation is not the end game for Adrian Bejan, who is “working on the next question: how to make the distribution of assets less unequal. It involves regulation, but with greater non-monetary contribution from individuals“.

The art of tracking, forensics, and the Constructal Law
[image error]
In this interview, Willem Larsen explores with Adrian Bejan what the Constructal Law can mean for a tracker, a subject he also further explored in several videos and interviews available online (cf. links here bellow).
In 2006, already A. Bejan and D. Gobin opened this kind domain of research thanks to a paper focused on the explanation of droplet geometries: splashes vs. splats – with obvious links with forensics…

Design in Nature – round table at the Helix Center
[image error]This round table about “Design in Nature” took place Saturday, April 22nd, 2017 at 2:30pm, at the The Helix Center, NY.
Prof. Adrian Bejan was one the five participants, and exposed his views on this topic, on the basis of the constructal law of evolution in nature.

Evolution in thermodynamics
[image error]
This review, published inApplied Physics Reviews, covers two aspects of “evolution” in thermodynamics. First, with the constructal law, thermodynamics is becoming the domain of physics that accounts for the phenomenon of evolution in nature, in general.
Second, thermodynamics (and science generally) is the evolving add-on that empowers humans to predict the future and move more easily on earth, farther and longer in time. The part of nature that thermodynamics represents is this: nothing moves by itself unless it is driven by power, which is then destroyed (dissipated) during movement.
Nothing evolves unless it flows and has the freedom to change its architecture such that it provides greater and easier access to the available space. Thermodynamics is the modern science of heat and work and their usefulness, which comes from converting the work (power) into movement (life) in flow architectures that evolve over time to facilitate movement.
I also review the rich history of the science, and I clarify misconceptions regarding the second law, entropy, disorder, and the arrow of time, and the supposed analogy between heat and work.

Wealth inequality
[image error]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.
