Mathematician Determines Most Efficient Way to Fold an Origami Doughnut
According to Scientific American, a mathematician has solved a decades-old puzzle about the fewest folds needed to turn a flat sheet of paper into a torus-shaped, doughnut-like origami form.

A mathematician has identified what is described as the most efficient technique for folding a flat piece of paper into a torus, or doughnut shape, according to a report by Scientific American.
The report states that the question of how many folds are required to create such a shape had remained unresolved for decades before this new solution was found.
Scientific American reports that the mathematician's method represents the smallest known way to achieve the origami doughnut, though the publication did not specify the exact number of folds involved or the researcher's full methodology in the available excerpt.
The findings, as described by Scientific American, contribute to the broader mathematical study of origami, which examines the geometric principles underlying paper folding and has applications in fields ranging from engineering to materials science.
Further details on the research, including the specific techniques used and any formal publication of the results, were not included in the available source material.
