Paul Kimmage: Who should we cheer - the guy who never wavered on doping or the guy who can't make up his mind?

Whenever anyone asked Jericho why he was a mathematician - some friend of his mother, perhaps, or an inquisitive colleague with no interest in science - he would shake his head and smile and claim he had no idea. If they persisted, he might, with some diffidence, direct them to the definition offered by G. H. Hardy in his famous 'Apology': 'a mathematician, like a painter or a poet, is a maker of patterns'.
