Undoubtedly first used in in geometry, the Golden Ratio, (called φ or «Phi» in honor of the Greek architect of the Parthenon, Phidias) represents a constant relation between two sizes of the same nature, such as lengths, surfaces, volumes or numbers. Phi is an irrational number, and signifies (1+√5)/2, i.e. a value approximating to 1.618.

Try an amusing and surprising experience: measure the relation between the first and second phalanx of one of your fingers, then the relation between the third and the second: you will obtain a number close to 1.618.

Idem for the relation between your hand and your forearm. And if you divide your own height by 1.618, you will obtain the height of your navel!

For hundreds, even thousands of years, the Golden Ratio has served to define ideal proportions between two geometric or mathematical entities. It is on the border of these two domains, and symbolizes their joining.
