4 Extra Debut. French mathematician Cédric Villani wrestles to tame a new theorem and reap the rewards. Memoir read by Julian Rhind-Tutt.

Rock-star mathematician Cédric Villani's magical mystery tour through the world of mathematics.

He describes the journey which sees him wrestling with and taming a new theorem that will win him the most coveted prize in his field.

Along the way he encounters obstacles and setbacks, losses of faith and even brushes with madness. His story is one of courage and partnership, elation and despair.

His account unlocks what goes on inside the head of a mathematician and captures where inspiration comes from. Blending science with history, biography with myth, Villani conjures up a cast of mathematical greats including the omnipresent Einstein and Villani's personal hero, John Nash.
