Fra’ Luca Pacioli defined the Golden Ratio as divine in his “De divina proportione” book of 1497.
Even known as Golden Section, this irrational number: (√5 + 1)/2 and its inverse:  (√5 – 1)/2 have played a fascinating attraction on artists, architects, musicians, and scientists since ages.
We can find its presence both in Nature and in Artifacts from Athens Parthenon up to Apple’s logo.
Flowers, petals, seeds, leaves, branches base their structure and organization on a kind of perfect geometrical ratio which stems from Fibonacci’s numbers and the correlated Golden Ratio.
Indeed, we can also say the opposite as scientists and mathematicians where able to see the perfection on Nature and quantify it by means of the Golden section.
