The problem of how to double the volume of a cube, also known as the Delian problem, has intrigued mathematicians for millennia. The great variety of solutions discovered over the centuries have used diverse tools, mathematical and otherwise. Recently, in 1936, Margherita Piazollo Beloch discovered a simple and elegant solution to this question. It uses a single piece of paper and a handful of folds. The solution has renewed interest in geometrical constructability problems, in particular those that incorporate origami. And ultimately, it's given rise to the field of origami mathematics.Faculty Sponsor: Shenglan Yuan
