Kirsty Young's castaway is the theoretical physicist, Professor Carlo Rovelli. His book 'Seven Brief Lessons on Physics' became one of the fastest-selling science titles of all time, catapulting him from the world of academia into the global spotlight. Committed to bridging the gap between science and art and making complex scientific issues comprehensible for the lay person, he is currently Professor of Physics at Aix-Marseille University.

Born in Verona, and an only child, he was encouraged to learn, to be independent and dreamed of travelling through space. By the age of 12 his long-standing rebellious streak was visible and he would later interrupt his university career to travel. Now in his early sixties, his academic career has seen him work in Europe and America and among the scientific community he is best known as one of the founders of Loop Quantum Gravity theory.
