Competence. Commemorative publication of Prof. Dr. John Erpenbeck on the occasion of his 70th birthday. Volume 4.

John Erpenbeck – a physicist by training, a writer who, from time to time, has drawn on the family tradition and continued to honor it – a notorious and powerful thinker on deeply intellectual matters, a known and sought-after pioneer and cross-examiner in educational matters and, finally, an unavoidable authority in matters of competence measurement and development! In short, the verdict after seventy years of living in Earthburg must be: Interdisciplinarity, openness of thought both in how and what, creativity in science and art, impact and respect in the academic, artistic, entrepreneurial, and social fields – all of this John Erpenbeck has truly more than justified.

The present volume is intended to give a small glimpse of his entrepreneurial spirit as a pioneer of the concept of competence, which has been dedicated to him in his honor on his birthday.
