'The diagonal of the square is incommensurable with its side.' Few words, but with unexpected implications: a number like this – neither whole nor fraction, thinkable but unknowable, wild, irrational – is a chaos element threatening the very order of things. The step from mathematics to heresy is short, and in Pythagoras’ time, mathematics could even cost you your life. A performance balancing mathematics and storytelling, where the story of Hippasus of Metapontum becomes an occasion to reflect on the role of mathematics in Western culture.
