As we were at pains to point out in the companion volume to this monograph, entitled Complexity in Chemistry: Introduction and Fundamentals, complexity is to be encountered just about everywhere. All that is needed for us to see it is a suitably trained eye and it then appears almost magically in all manner of guises. Because of its ubiquity, complexity has been and currently still is being defined in a number of different ways. Some of these definitions have led us to major and powerful new insights. Thus, even in the present monograph, the important distinction is drawn between the interpretations of the concepts of complexity and complication.
