May I mention to the authors a recent article in the New York Times which considers the solution an optimal densest packing – a world record!
Applications and games often nourish one another in mathematics
Several chapters of « Hidden Wonders » have been devoted to folds. This is an important area of mathematical science which deals with the contrary properties of a surface, like a piece of paper, spread out on a plane or packed tightly into a crumpled ball. The book describes several technical applications of folds so different ,from « haute couture » to electrolysis.
