“… suddenly, totally unexpectedly, I had this incredible revelation. It was the most important moment of my working life. Nothing I ever do again … it was so indescribably beautiful, it was so simple and so elegant, and I just stared in disbelief for twenty minutes, then during the day I walked round the department. I’d keep coming back to my desk to see it was still there – it was still there.” – Grote wiskundigen zijn toch een bijzonder slag mensen – je hele leven wijden aan het bewijzen van iets schijnbaar triviaals als een stelling van Fermat.
