The Royal Society (recently the focus of a minor rebellion by some of its more scientifically honest members) has been found to have made a mathematical blunder that would best be described as really, really, really, dumb. Something a middle school student might have done...but certainly not something you would expect the smartect guys in the room (well at least they think they are) to have committed.
