As an interdisciplinary journal of landscape architecture, LA+ DESIGN magazine delves into the role of design in times of transformative technological and environmental change where nothing on Earth, or even in space, seems beyond the reach of designers.
In the last issue (09, Spring 2019) of LA+DESIGN engineer and physicist Adrian Bejan outlines his constructal law, which predicts natural design and its evolution in engineering, scientific, and social systems in his article “The Evolving Design of Our Life“.
Time seems to fly as we age. The Keep It Juicy! blog author, Helen Mitternight, talks to physicist Adrian Bejan about the physics of how that happens and how to slow time.
“Adrian Bejan, J.A. Jones Professor of Mechanical Engineering at Duke University, delivers a thought-provoking analysis of the mechanics of life, energy, and the science of our natural world.” – futuretechpodcast.com

“What nature try to do on its own, we tend to do in our life movement, because we too are part of the flowing nature.”
Ephrat Livni exposes Prof. Bejan’s Constructal view on the passage of time, on the basis of a peer-reviewed publication to be soon published in the European Review journal, in this recent online article.
In this one-hour long interview on the Ecosomatics podcast, Professor Adrian Bejan discusses the Constructal Law & The Physics of Life.
“The fastest animals and vehicles are neither the biggest nor the fastest over lifetime” is the subtitle of A. Bejan, U. Gunes, J. D. Charles, and B. Sahin in their Nature Scientific Report published the 27 August 2018.
Thanks to their theory, in this article, the authors explained phenomena such as the emergence of animal “outliers”: higher speed at smaller body mass.
They show that what accounts for the animal outlier also accounts for the vehicle outlier: military jet fighter are smaller and reach speeds higher than the biggest commercial aircraft. Yet, like the cheetah, the jet fighter spends most of its active life at rest, on the ground, out of sight. This new view gives the word ‘outlier’ a different meaning: the jet fighter is the outlier because, during its overall lifetime, it is slower than the bigger commercial aircraft, which spend most of its time flying.
This new meaning is in fact the oldest, taught by Aesop in his fable “The Tortoise and the Hare”: what matters in the life of the mover is the movement – i.e. the territory covered, the speed averaged – over the whole lifetime.
In a recent paper published in the prestigious “Energy”, Bejan presents his view on Thermodynamics and Science itself.
“Science is like a civilized territory that improves, prospers and expands because it makes life better for the people who belong to it. It expands as long as it keeps producing useful things, which attract people. The civilized welcome the newcomers, the nobodies, provided that they obey the laws, the discipline. People join because their lives become better that way.”
“To fight the barbarians who pillage on the perimeter is a necessary and unpleasant effort, a nuisance, not the objective. As the defeated barbarians are assimilated and civilized, the civilized territory expands and, as a result, life, peace, movement and freedom flourish. The civilized territory that does not fight the pillagers is destined to disappear along with the good way of life that it was sustaining.”
“Thermodynamics, like all the useful artifacts (e.g., science) produced by the civilized, is no different.”
