Can Geometry explain Life? The answer is YES. But how to argue it? Writing this essay has been like traveling to an unknown and remote country, a true discovery, a mental adventure to understand to what extent we are CHILDREN OF GEOMETRY. It is an eminently graphic study, which, starting from the most elementary conception of geometry, goes deep into the structure of three-dimensional space, until it is linked to the processes that constitute the very basis of Life. This research brings to the surface implications of geometric developments in multiple manifestations of the human mind: mathematics, physical and biological sciences, philosophy and cosmology, religion and symbology, art, technology and design, music and dance.... The author's intention is to shed some new light on such an intricate subject, and I dare to recommend the reader to approach it without expectations, allowing himself to be carried away by the book's argumentative current.
