Description Illustration of Vogel's formula of the pattern of sunflower florets (see article) for n=1 to 500, using the polar coordinates equations r = c \sqrt{n} and \theta = n \times 137.5^{\circ} (where 137.5° is 55/144 of a circular angle, and 55 and 144 are both Fibonacci numbers -- the exact angle should technically be 360/(((sqrt(5)+1)/2)+1), or 137.507764...). Can be produced using the following MATLAB code:
