Jack Klaff is a writer, performer and occasional academic. He has held four visiting professorships at Princeton University and was for three years Professor of the Public Understanding of Science at Starlab in Brussels. Professor Klaff has worked closely with Intelligence Squared, for whom he has interviewed a number of aged Nobel-winning physicists. Among his unusual performing gigs have been a talk at the European Parliament and his theatrical trilogy about male/female relationships – performed in Saudi Arabia. His next book, Does Science Have all the Answers? could be even shorter than this one, containing just the word ‘No’.
