Sigmoid Curve

"The Sigmoid Curve sums up the story of life itself. We start slowly, experimentally and falteringly, we wax and then we wane. It is the story of the British Empire and of all empires always. It is the story of the prodict life-cycle and of many a corporation's rise and fall. It even describes the course of love and relationships."
Charles Handy in 'Beyond Certainty'
