Storch, a British sculptor, got the idea for his sculpture from mathematicians Prof. Bernd Krauskopf and Dr. Hinke Osinga from the University of Bristol. In 2004, Krauskopf and Osinga created their own model “sculpture” representing the Lorenz manifold using 25,511 crochet stitches. Storch’s sculpture is made of steel, rather than of fabric, and is considered to be more accurate. In order to create the complex form of th sculpture, Storch used a technique where central surface areas are compressed and peripheral areas are stretched. Measuring 780 X 780 X 480 mm, the Manifold is an extraordinary piece of stainless-steel craftsmanship, combining mathematics and art.
According to Storch, the collaboration with the two Bristol researchers started after he meet the two in a conference. After seeing Storch’s other works Krauskopf and Osinga suggested that he try and make a metal model of the Lorenz manifold, which they studied parting the framework of their academic research. Storch worked on the sculpture using a computer-aided design (CAD) representation of the manifold. However, he admits that even with a very precise model in front of him, creating the sculpture was a challenge. The strength of the steel played a key-role in maintaining the complex structure, especially given the narrow metal band used.
A mathematical background to the Krauskopf and Osinga work on the Lorenz manifold can be found on their “Crocheting the Lorenz manifold” article (PDF). A slightly less technical discussion of the subject can be found here.
