And I don't know about you, but I find that rather beautiful. Complex symmetry, circle, sphere, spiral, parallel line, and golden angle. The world around us seems to be teeming with harmonic relationships, and plants are no exception. According to the ancient Greeks, the world appears beautiful because it is populated by plants, and plants teem with perfect geometries… yet we now know that perfection is not of this world, and certainly not among living beings. And if the beauty of plants so often strikes us, it is perhaps because we see in them forms already encountered—or imagined—within our own minds. Geometric forms that seem almost perfect, abstract, responding for all eternity to absolute rules. In this sense, they abound with what the Platonists consider one of the highest forms of all beauty, that which is found in mathematics and symmetry. This beauty, of which circles—like spheres—are the quintessence, being the only forms to have an infinite number of axes of symmetry, one in the plane, the other in space. Where do some of the springs flow from?
