Thermodynamics Today

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.”

Human innovation and enlightenment explained by Physics

 Ephrat Livni reviews, in this Quartz article, the application of Constructal theory to the physical description of innovation and human illumination. Livni article refers to a recent research paper on Social organization by A. Bejan  and other researchers: Social organization: The thermodynamic basis.

Simply put, the theory explains that “this theoretical framework also reveals the physical meaning of innovation: It is a local design change that liberates the flow over the entire territory inhabited by the organized movers”. In brief,  innovations open new pathways that generate opportunity for more movement for everyone around them.

And, as the local invention attract sudden movement, then the whole flowing area, or population, becomes wealthier than before. According to Bejan, “this is the tangible, or physical effect of a single idea, and why research, science, questioning, and tinkering benefit the whole of society”.

Social organization emerges by Physics

Social organization: The thermodynamic basis

Constructal Law brings social organization under the big tent of physics

Fig_agrregatesDirection of evolution of humans aggregates and technology in the Economics of ScaleIn view of the complexity and diversity of contemporary social organization, why do individuals came to live (to move) together, to organize themselves in the first place ? Constructal law shows that social organization is a natural phenomenon rooted in the physics of economies of scale. It is a reflection of the physics reality (bio and nonbio) that it is easier to move 1 unit of mass in bulk than to move 1 unit individually. This discovery is the connection between physics and social organization, which brings social organization under the big tent of physics.

The new theoretical framework also reveals the physical meaning of innovation: It is a local design change that liberates the flow over the entire territory inhabited by the organized movers.

Personal Aircraft: Why The Revolution Won’t Happen

According to Prof. Adrian Bejan views, captured into this article published by Aerospace America, a fundamental law of physics will prevent the Personal Aircraft revolution to happen.

The passenger drones, sky taxis, and other personal aircraft names are buzzing and exciting the aviation industry – but Prof. Bejan explains us that flying is for faster travel over long distances, and not for short distances. In this last case, the economical movement is on land, and it is slower.
