This book is an index of mathematical functions, translated into visual form. Based on the work of mathematician Herwig Hauser and his equations with striking geometrical properties, the project explores how abstract formulas can be rendered as 3D images.

By focusing on the aesthetic side of mathematics, it offers an alternative and accessible way to engage with a field often seen as complex or obscure. Rather than presenting dense theorems, this edition invites readers to explore mathematical ideas through form, symmetry, and visual curiosity—turning them into a tangible and sculptural experience.
