Mathemalchemy is a collaborative art installation conceived as the brainchild of mathematician and physicist Ingrid Daubechies and fiber artist Dominique Ehrmann, and driven by the energy and enthusiasm of 24 mathematical artists and artistic mathematicians. The installation celebrates the creativity and beauty of mathematics. Playful constructs include a flurry of Koch snowflakes, Riemann basalt cliffs, and Lebesgue terraces. It was designed and constructed during the pandemic, and has been touring North America since January 2022; it will soon move to its 5th exhibition venue. The talk will review the genesis and creation of the installation, and highlight some of its mathematical features.
