A sociologist, physicist and mathematician were on a train travelling through Wales when, in the first field they passed through they saw a lone black sheep. ‘Look’ says the sociologist ‘all the sheep in Wales are black.’ ‘You can’t say that’ says the physicist ‘the most you can deduce is that there is at least one black sheep in Wales.’ ‘You are both wrong’ says the mathematician ‘all you can say is, in a field in Wales is a sheep, one of whose sides is black.’
