The document explores the concept of incommensurability in mathematics, focusing on the relationship between numbers and their square roots. It introduces the square roots spiral as a visual representation of incommensurable magnitudes. The text then contrasts the square roots spiral with two other well-known spirals: the logarithmic spiral and the Archimedean spiral. It details the construction and properties of each spiral, highlighting similarities and differences among them. Finally, the document concludes by suggesting the potential use of these spirals in defining a metric relationship for a specific geometry called CPS Geometry.
