Pine Cone Scale Pattern — Fibonacci Spiral at 2:1 Macro
249.00 د.إ
A Scots pine cone photographed at 2:1 macro — the scale spiral arrangement showing the Fibonacci number sequence in its packing geometry, the two opposing spiral sets of 8 and 13 spirals visible simultaneously.
Description
Pine cone scale arrangements follow the Fibonacci number sequence with remarkable precision — in most species, the clockwise and counter-clockwise spiral families contain Fibonacci numbers (typically 5 and 8, or 8 and 13) that result from the way the scales are initiated at the cone’s growing apex in the golden angle phyllotaxis pattern. At 2:1 macro reproduction, the Scots pine cone’s scale spiral pattern is fully legible: the clockwise family of 8 spirals and the counter-clockwise family of 13 spirals are simultaneously visible as two overlapping spiral grid systems crossing at each scale position. This image was made with the cone at the optimal orientation to maximise the visual legibility of both spiral families — a slightly oblique view of the base that foreshortens the cone’s length while preserving the circular cross-section geometry. The scale surfaces, with their woody texture and circular seed-protection geometry, are resolved in the raking sidelight.
