- Suzan Mazur, Adrian Bejan: “Growth Is Not Evolution”, Science, The Huffington Post, 20 April 2015.
This article from the Journal of Heat Transfer unveils the physics meaning of optimization, knowledge and design evolution, and why these concepts and human activities are profoundly useful for human life.
The design in nature phenomenon facilitates access for everything that flows, evolves, spreads, and is collected: river basins, atmospheric and ocean currents, animal life and migration, and technology (the evolution of the “human-and machine species,” wealth, life). This phenomenon is summarized by the constructal law: the occurrence and evolution of designs in nature, its time direction.
Notably, the constructal law accounts for contradictory end-design statements such as minimum entropy production and maximum entropy production, and minimum flow resistance and maximum flow resistance.
The constructal law shows that lists of great or classic books are hierarchical designs that arise naturally to organize the swelling flow of literature.
Every snowflake conforms to only one architecture: a flat star with six fishbones connected at the center.
What’s more, that structure is predictable provided that we recognize the underlying principle: first, that something flows, in this case heat, and, second, that the natural tendency of all flows is to evolve
into architectures that provide easier access.
It’s another example of the constructal law.
Adrian Bejan, professor of mechanical engineering and materials science, describes his research into the constructal law of physics that he described in 1996 and how it applies to evolution in a talk given to prospective undergraduate students.
