Adrian Bejan Talks Constructal Law

Adrian Bejan, professor of materials science and mechanical engineering at Duke University, recently sat down with film director Dan Dimancescu to describe the nuances and uses of constructal law, which he penned in 1996. The law states that, "For a finite-size system to persist in time (to live), it must evolve in such a way that it provides easier access to the imposed currents that flow through it." In other words, systems that are allowed to change will always do so in a way that increases their access to flow. Bejan has used this concept to explain everything from the shape of a snowflake to the evolution of modern aviation. For more information on constructal law, visit constructal.org.

Constructal Law Explained

Adrian Bejan explains how constructal law underpins the natural organization and flow of everything in nature from rivers to evolution, providing a single unifying law that can describe many processes and systems. To illustrate his point, Bejan shows how his knowledge flows through students and readers throughout the world.

Behavior Transformation

Adrian Bejan explains how understanding constructal law can influence how scientists, engineers and many other professionals think and work.
