Limited first edition: Coloring and learning book "The Magic of the Golden Ratio", hardcover, 48 pages

The time has come: The first coloring and learning book about the magic of the golden ratio is now available for a limited time in a small, limited edition. It is, so to speak, the prototype before the book goes into bookstores.

The book explores the question of what constitutes the magic of this mathematical peculiarity and why the resulting proportions are called "divina proportio", or divine proportion.

Behind this question seems to hide a deep, almost mystical connection between mathematics, art and nature, which manifests itself in aesthetic harmony and appeals to us on a fundamental, almost unconscious level.

This book provides children (from 12 years), teenagers and adults with an
easily understandable, playful approach to this magic.
