About this Product
A spiraling pendant made from the number Phi, the golden ratio. This pattern is the same found in many places in nature including seashells, and sunflowers. Phi is one plus the square root of five all over two, or approximately 1.618033988749894848204586834 as a decimal. Here is a link to a video by Vi-Hart on Khan academy about the golden ratio and other numbers found in nature. https://www.khanacademy.org/math/recreational-math/vi-hart/spirals-fibonacci/v/doodling-in-math--spirals--fibonacci--and-being-a-plant--1-of-3
