Marcus du Sautoy on mathematics

Marcus du Sautoy wasn't particularly good at maths at school; but a teacher spotted his aptitude for abstract thought and he started reading, and enjoying, journals filled with mathematical proofs. His thesis on the mathematics of symmetry launched him as a world class mathematician. And before he dies he wants to know: can you predict the properties of the next symmetrical object that could possibly exist in a hundred thousand dimensions or more? Marcus talks to Jim Al-Khalili about his passion for the performing arts, as well as mathematics; and why, for him, mathematics is as much a creative art as a science. Producer: Anna Buckley.
