I mean that there’s a universal urge or tendency toward design and organization that changes over time in a discernible, seemingly goal-oriented direction. I don’t mean evolution in the Darwinian sense. If you have more efficient flow-whether it’s fuel and air flowing through a combustion chamber or food matter passing through the gut of an animal-you have the correct direction of evolutionary design.Įvolution is a crucial part of how we need to define efficiency. The goal of everything is to seek greater access or easier flow and to morph freely in that direction. That would be correct, except that first you need to have an understanding or definition of what efficiency is. Would it be overly reductive, then, to say that everything everywhere seeks efficiency all the time? Blood flow and water flow essentially evolve the same way. In each case, they evolve freely to reduce friction and to flow better-to improve themselves and minimize their mistakes or imperfections. They describe the ways that animals move and migrate, the ways that river deltas form, the ways that people build fires. That’s physics, stage four-more precise, more specific expressions of the same idea.įlow systems are everywhere. But I would specify and say that the tendency is toward evolving freely-changing on the go in order to provide greater and greater ease of movement. The Constructal Law says there’s a universal evolutionary tendency toward design in nature, because everything is composed of systems that change and evolve to flow more easily.
Your new book is premised on a law of physics that you formulated in 1996.

In your magazine and on your TV channel, we see many animals doing this-extending their reach with tools, with intelligence, with social organization. Therefore all the things that we make-our tools, our homes, our technologies-are natural as well. One thing that came directly from Charles Darwin is that humans are part of nature, along with all the other animate beings. In Latin, nature-physics-means “everything that happens.” Our narrow definition of the discipline is something that’s happened in the past hundred years, thanks to the immense impact of Albert Einstein and atomic physics and relativity at the turn of the century.īut we need to go back farther. Does that mean we can unite all behavior under physics?Ībsolutely. According to your book, physics describes the actions or tendencies of every living thing-and inanimate ones as well. To wrap our heads around this counterintuitive premise, National Geographic recently spoke with Bejan about the physics of life, the universe, and everything. Harking back to the original definition of the discipline-“knowledge of nature” in Greek-he ultimately concludes that “life and evolution are physics.” But his new book, The Physics of Life: The Evolution of Everything, may be the broadest consideration yet. The same principles of physics, he argues, can be applied to all things that move, morph, and flow, from sports and technology to air currents and population growth, migratory patterns and social hierarchy.īejan isn’t the first person to study behavior as physics, or to use physics to describe wider systems. But the iconoclastic energy scientist-a mechanical engineering professor at Duke University and one of the world’s foremost experts on thermodynamics-thinks of pretty much everything else as well. Send us feedback.When you think of physics, what comes to mind? Atomic energy? Gravitational waves? Maybe Newtonian equations?Īdrian Bejan thinks of those things too.
