How do the perspectives of an interested citizen, an engineer, and a cyberneticist differ on a robot? This introduction to the world of cybernetics provides the basics and discusses the most important thought leaders, models as well as theories. Practical examples from a variety of fields (biology, ecology, engineering, society, and politics) are used to illustrate the basics. Readers are prompted to reflect by questions at the end of the chapters, and the author does not owe the answers. A central theme in all cybernetic considerations and guiding theme of the book are information exchange and communication. The target group Students from technical, scientific, and interdisciplinary courses of study Lecturers with courses on cybernetics/System Dynamics Readers interested in the facets of cybernetics The Author Dr.-Ing. E. W. Udo Küppers studied engineering in Düsseldorf and Berlin. After scientific activities in research institutions and participation in international R&D projects, he has been leading the independent research group Küppers-Systemdenken since 2001. The translation was done with the help of artificial intelligence. A subsequent human revision was done primarily in terms of content.
