There is more on this ratio, irrational number rather. According to this Discovery Channel (or was it BBC??) programme, this ratio governs our perception of beauty. The ratio of the width of the nose to that of the mouth; the chin to that between the cheeks, length of nose to that of the face all come close to this ratio. the closer it is the more beautiful we see the person as. Infact, doctors have constructed the perfect beauty mask based on this ratio and elizabeth hurley who was one of the presenters fits in quite nicely.
and speaking of cable channels, why don;t you guys start one??
