★A meeting place between mathematics and other fields that brings together mathematics, art, literature and society.
★An interdisciplinary and narrative vision essential for those who teach mathematics.
★New Math Letter carries on the themes and style of the magazine "Lettera Matematica Pristem", starting with the language and methods of mathematics, wishes to explore the world around it, its connections with other fields of knowledge and its applications to the description of reality.

With the awareness that mathematics can also be narrated in a non-specialized language, following its history, its dialogue with other disciplines, and its more and more important role in our society, New Mathematical Letter aspires to renew methods and language for communicating and teaching mathematics with an interdisciplinary approach. It proposes a vision of mathematics understood as a habit of thought, making us appreciate its countless applications to everyday life, its cultural depth and its role in history and in philosophical, scientific, technological, economic and social debate, up to its contacts with the artistic and literary fields.

The traditional historical and interdisciplinary view also permeates this volume.
Di Martino and Mazzuferi present the properties of helical surfaces that later become works of art.
Fano and Pietrini highlight that modern science does not follow a single method but uses many methods that connect and complement each other, in a form of "methodological opportunism" of which Galileo's considerations of infinity and continuity are examples.
Maria Piera Manara illustrates some considerations of the Milanese scientists on the foundations of mathematics formulated by the school of Peano.
Paoloni and Rogora talk about Paolo Ruffini two hundred years after his death.
Albert Vilalta illustrates the Innovamat educational project, which originated in Spain but is now at international level.
