How do you create a knot in an elastic wire so that it can be turned into different, stable, three-dimensional forms? It can be worked out by trial and error, but it’s easier done with a computer program developed by EPFL. In fact, the team there has already found lots of solutions, including some that are completely new. Besides the playful aspect, however, these ‘knots’ are also useful in developing novel materials and foldable structures.
