A History of Folding in Mathematics

More about the book

The book explores the overlooked discovery of Margherita Beloch Piazzolla, who demonstrated that a segment of length cube root of 2 can be constructed using a single paper fold, contrasting with the impossibility of solving the Delian problems with traditional tools. It delves into the historical neglect of paper folding as a mathematical practice, questioning its marginalization and examining how the mathematical insights gained from this technique were perceived and conceptualized over time.
