“In contrast, other fields, such as biology, economics, health sciences, among other, have found practical applications of complexity in their disciplines. The purpose of this work is to show some possible applications of complexity, not necessarily in the traditional field of chemical engineering, but where clearly chemical engineers can uniquely contribute due to our formation and basic elements of thermodynamics, and processes analysis, compared to other disciplines, in matters of study that are not the classical chemical engineering applications, but where their application is necessary, even not being chemical processes.”

“A relevant anecdotic, is the strong debate including economic Nobel Prize winners such as Kenneth Arrow, 1972 winner, and Paul Krugman, 2008 winner, the first in favor and the last against the application of complexity in economics. This debate is agitated by the use of defiant expressions used by the authors, such as they have ‘changed economic thinking’, which generated comments like the other ‘has just invented…economics’. This work, by the way, doesn’t want to generate such comments, instead, its purpose is to reinforce arguments to the fields of action that chemical engineers can, and must be prepared to participate.”
