Maths, Borges and dance

Just been to "The nineteenth step" at Laban. A collaboration between the composer Dorothy Ker, mathematician Marcus du Sautoy, choreographer Carol Brown and sculptor Kate Allen, taking as its starting point some of Borges's stories. Marcus danced a proof of the irrationality of the square root of three (that was the bit of dance that I could best relate to). Stimulating discussion afterwards about connections and interdisciplinary collaborations, particularly around space and dimension. An interesting evening, in the best sense.
