r=c√n, Ɵ=n*137,5 or another TE stereotype…
On the Wikipedia you can read about sunflowers. Some genious have stated this matematical formula to set the pattern made by the florets in the head.
A model for the pattern of florets in the head of a sunflower was proposed by H Vogel. This is expressed in polar coordinates where θ is the angle, r is the radius or distance from the center, and n is the index number of the floret and c is a constant scaling factor. It is a form of Fermat's spiral. The angle 137.5° is related to the golden ratio and gives a close packing of florets. This model has been used to produce computer graphics representations of sunflowers.
Don’t ask med what use it has…
We loved Italy and we took some family photos among the sunflowers as well .

Pretty "portrait" of this sunflower. The colours are nicely saturated and contrast really well against the polarized sky. Good pov and having the flower point towards the corner.
