Crocheting the Lorenz manifold

(For text and crochet instructions, see the preprint)

Dr Hinke Osinga and Professor Bernd Krauskopf have turned the famous Lorenz equations that describe the nature of chaotic systems into a beautiful real-life object, by crocheting computer-generated instructions. Together all the stitches define a complicated surface, called the Lorenz manifold.

The final result consists of 25,511 crochet stitches and took Osinga about 85 hours to complete. However, this wasn't just done for fun. Their work gives insight into how chaos arises and is organised in systems as diverse as chemical reactions, biological networks and even your kitchen mixer.

A bottle of champagne was offered to the first person who would produce another crocheted model of the Lorenz manifold. It only took two weeks before three people had sent emails to announce that they had finished! Please check out the other Lorenz manifolds. If you have finished your crocheted Lorenz manifold, please send a photograph of it!


Media interest
