Adrian Bejan: “Growth Is Not Evolution” | Suzan Mazur

“I’m not an artist now, I’m a physicist, one who is at ease with images and the fact that science is images. Geometry is images or figures or relations between figures. Mechanics requires pictures that move.”

“In your book, The Origin of Life Circus: A How To Make Life Extravaganza, you interview Rockefeller University physicist Albert Libchaber, who said life is geometry because geometry is physical. I wrote down this line because this is correct. And geometry is macroscopic. Geometry you see it and you pick up a pencil and you draw it. It has nothing to do with chemistry or genes. Zero.”

“I agree with Branscomb to the extent that for anything to move, anything to flow, it must be driven. This is the reason why in my statement of the constructal law I used the word “imposed.” That word imposed means driven, dictated, pushed, pulled.”

“Everywhere I look, I see phenomena that confirm the constructal law, phenomena that tell me and my students that life is physics. That evolution is also a physics phenomenon. Evolution has direction, therefore it is not random. Again, as an educator, I can also tell people what knowledge is and what information is not.”

Design in Nature

The Constructal Law

1. Life is flow: all flow systems are live systems, the animate and the inanimate.

2. Design generation and evolution is a phenomenon of physics.

3. Design have the universal tendency to evolve in a certain direction in time.

“The Constructal Law teaches us that nothing operates in isolation; every flow system is part of a bigger flow system, shaped by and in service to the world around it.”

“For a finite-size system to persist in time (to live) in must evolve in such a way that it provides easier access to the imposed currents that flow through it.”

“Constructal Law is another step in our ongoing effort to understand the world around us. It reveals that design in nature is not the result of chance but a universal law.”

“Nature is governed by the tendency to generate shapes and design that evolve in time to reduce imperfection. Design evolution never ends.”

“The rise of humanity is not a radical break from the past bit a chapter in the larger story of the Earth’s long history of flow, design, and evolution. We are part of nature; its oneness includes everything even us. Our special gift is not the ability to act apart from nature but the ability to generate complex and evolving natural designs that allow us to move more mass faster, farther, with longer lifetimes…”

 “The road to easier flowing consists of balancing each imperfection against the rest. All the components, working together to create a whole that is less and less imperfect in time.”
