Mathematician Vicky Neale is keen to explain why mathematics is beautiful but also to work out whether beauty can itself be explained mathematically. There is a rich tradition of thought here going all the way back to the Greek philosopher Pythagoras, whose understanding of mathematical relationships sits at the origins of western music. Vicky talks to guitar technician Eltham Jones and to Prof Thomas Johansen from the philosophy faculty in Oxford.
