This unique book overturns our ideas about non-Euclidean geometry and explains the role of the "golden ratio" in Euclids Elements. It highlights a new view on Euclids Elements and the history of mathematics based on Proclus hypothesis. It describes a general theory of "recursive" hyperbolic functions based on the "golden, " silver, " and other "metallic" proportions. The book contains an original solution of Hilberts Fourth Problem for hyperbolic and spherical geometries, and puts forward a problem searching for new hyperbolic and spherical worlds of nature based on this solution. For the first time, the book describes the "golden" qualitative theory of dynamical systems based on the mathematics of harmony. It is intended for a wide range of readers, who are interested in the history of mathematics, non-Euclidean geometry, Hilberts mathematical problems and dynamical systems.
