A sunflower, for example, looks the same as any other sunflower; its visual rhythm is always the same: an outer circle of golden yellow leaves, an inner circle of dark brown bushy matter. You could find out the exact mathematical calculation for reproducing a picture-perfect copy on a computer. So if you took a photo of a sunflower and loaded it onto your computer, what is visually displayed on your monitor has a mathematical and scientific calculation running behind it. It has its own rhythm.
