‘Knitting Is Coding’ and Yarn Is Programmable in This Physics Lab

Dr. Reis grapples with the likes of long-overhand shoelace knotting, climbing knots, basket weaving, surgical sutures, and how to pass on the art of surgical-knot craftsmanship to robots. Together, they had derived a conjecture: All knittable stitches must be ribbon knots. Back in February, Mr. Markande (who started knitting only recently for the sake of science) thought he’d found an example of an unknittable ribbon knot, using a knots-and-links software program called SnapPy.
