Marcus du Sautoy on Jorge Luis Borges

Mathematician Marcus du Sautoy chooses the blind Argentinian writer Jorge Luis Borges for Great Lives. He is fascinated by the connection between the creator of 'The Library of Babel' and science - did Borges really understand notions of infinity and space ? Biographer Jason Wilson adds colourful detail to the life of a great writer whom he insists was just being impish when it came to the weighty matters that have excited more than one mathematician over the years. The programme includes beautiful recordings of Borges in conversation in 1971. Marcus du Sautoy is the Charles Simonyi Professor for the Understanding of Science. The presenter is Matthew Parris, and the producer is Miles Warde.
