18. 18 The chambered nautilus is a sea creature that belongs in the same class as the octopus. Unlike the octopus, it has a hard shell that's divided into chambers. As the nautilus matures and grows, it periodically seals off the shell behind it and creates a new, larger living chamber. The shells of adults may have as many as 30 chambers. This growth process yields an elegant spiral structure, visible when the shell is sliced to reveal the individual chambers. This spiral is linked to a number drawn known as the golden ratio.

He showed that the human body is built with each part in a definite golden proportion to all the other parts. � Pythagoras (560-480 BC), the Greek geometer, was especially interested in the golden section, and proved that it was the basis for the proportions of the human figure.
