No scientific discovery of such magnitude as the Construtal Law has ever been easily predicted before it happened. Yet, nothing is more powerful than an idea ready to be born. Working in manufacturing technologies, in international economics, in international law and relations, in knowledge production, in science and technology for innovation, and the spread of ideas and knowledge over humankind’s history, in human capital and human performance, we had much of an inkling for a long time. Yet, when Adrian Bejan discovered and expressed the constructal law of design in nature and human systems we were overly pleased. It all makes sense today in a way in which the Michelson-Morley experiment made everything surrounding the “ether” make sense. We prefer to call it aetherus, as the Roman would in Latin if they only tried to know about it, of course. Hence AEqulibriEA.
