The third German edition is not merely a translation of the revised Hungarian edition. Károly Simonyi personally edited, supplemented, and authorized the German edition in his later years. The book covers the history of physics—interconnected with the development of mathematical and philosophical thought—from its early beginnings to the present day. In addition to the main text, there are over 400 quotes from the works of significant physicists and contemporaries in the wide margins. The main text is further structured—sections that require deeper expertise are printed in smaller type. A large portion of the over 700 illustrations, including drawings, tables, photos, and facsimiles, are also arranged in the margins. Detailed captions provide a wealth of additional information. The included plate section allows for a cohesive overall presentation.
