Geometry at work: Sea animals, Fruits and Vegetables and Plants
The nautilus (from the Latin form of the original Ancient Greek ναυτίλος, ‘sailor’) is a pelagic marine mollusc. Although not a golden spiral, the nautilus shell presents one of the finest natural examples of a logarithmic spiral.
Geometry of fruits and vegetables
When sliced in half, the majority of the depicted fruits and vegetables will display a geometric shape or pattern, based on symmetry or platonic solids.
The arrangement of leaves
Phyllotactic spirals form a distinctive class of patterns in nature, depicting the arrangement of leaves on a plant stem.
The basic patterns are alternate, opposite, whorled or spiral, many of them arranged based on consecutive fibonacci numbers.
