Did you know that while youâ€™re hooking a flower, youâ€™re using geometry? At Sheffield Universityâ€™s Festival of the Mind exhibition, artists and academics are using crochet to help explain hyperbolic surfaces â€“ surfaces which donâ€™t lie flat, and which curve outwards at every point, like mushrooms, pinecones and ferns. Says organiser Kerry Rose: â€œThis can be replicated with crochet by increasing at the same rates at regular intervals to achieve a variety of shapes. Crochet is unique in that it is the only tactile 3D format to demonstrate these principles!â€
So people can learn about the geometry in nature, Kerry is creating a â€œtactile crochet hyperbolic forestâ€. The installation is at Bank Streets Arts from 14â€“25 September. Kerry is inviting crocheters to send in their creations, or share them on Facebook â€“ just search for crochetukhyperbolicforest.
