In a focus-stacked photograph, Ethan Beckler () captures a single grain of sand balanced on a knotted human hair using OM System equipment. This image highlights a convergence of biology, geology, physics, and photography at a microscopic scale. The hair’s overlapping cuticle scales create a textured surface that, combined with friction and the sand's light weight, keeps the tiny particle securely balanced, revealing a detailed world hidden from the naked eye.
