Greeks first used this number in buildings because they thought it was the beautiness number so, if the buildings proportions were based on Phi number, the construction would be beautyful as well. Buildings such as in the Partenon.
Since Greeks, Phi number became more used in other countrys in architecture (As in Eiffel thower) but also in paintings as in "A Venus Birth" or in "La Gioconda"

Among all rectangles, there is one which is more beautiful for the people. It´s an special rectangle. If you divide the longest side by the shortest side you obtain 1,6180339... and if you cut a square whose side is equal to the small side of the rectangle we obtain a rectangle similar to the original. This rectangle is used by designers, engineers, painters... to do a lot of things: credit cards snuff packages, buildings, pictures, etc.
