Romanian-born American mechanical engineer Adrian Bejan's 2012 depiction of how the geometry of flow structures found surrounding river deltas and lung bronchi are both governed by one law of nature, which Bejan calls "constructal law". [4] |
“I perceived something in nature (whether living or lifeless, animate or inanimate) that manifested itself only in contradictions and therefore could not be expressed in any concept, much less any word. It was not divine, for it seemed irrational; not human, for it had no intelligence; not diabolical, for it was beneficent; and not angelic, for it often betrayed malice. It was like chance, for it laced continuity, and like providence, for it suggested context. Everything that limits us seemed penetrable by it, and it appeared to dispose at will over the elements necessary to our existence, to contract time and expand space. It seemed only to accept the impossible and scornfully to reject the possible.”
“The author must have been led to his strange title by his continuing work in the physical sciences where we often make use of comparisons drawn from the world of human behavior so that things which are essentially remote from us may be brought a little nearer; and in the novel, in a case concerning morality, doubtless the author was seeking to trace an expression used as an analogy in chemistry back to its origin in the life of the human spirit. [The advertisement concludes with a general remark, the essence of which is] there is after all only one nature, and that even in our human zone of it, the cheerful zone of reason and freedom of choice, still there are traces, in the passions, of bleak and irresistible necessity.”
“Why should systems consisting of components as different as electrons, atoms, molecules, photons, cells, animals, or even humans be governed by the same principles when they organize themselves to form electrical oscillations, patterns in fluids, chemical waves, laser beams, organs, animal societies, or social groups.”
“Echoing the scientific community’s conventional wisdom, this famous man asserted that three-shaped structures that abound in nature—including river basins and deltas, the air passages in our lungs, and lightning bolts—were aléatoires (the result of throwing the dice). That is, there is nothing underlying their similar design. It’s just a cosmic coincidence.”
“Design in nature as a scientific discipline, [is] centered on a physics law of design and evolution: the constructal law. This law sweeps the entire mosaic of nature from inanimate rivers to animate designs, such as vascular tissues, locomotion, and social organization.”
