How many “hidden turbulences” in Van Gogh's “Starry Night”? The illusion of movement in “The Starry Night” is so vivid that scientists analyzed how closely van Gogh’s depiction mirrors the actual physics of atmospheric turbulence. They discovered two “hidden turbulences”: 1️⃣the sizes of the 14 whirls or eddies and their relative distance and intensity, follow a physical law known as Kolmogorov’s theory of turbulence. ℹ️In the 1940s, Soviet Russian mathematician Andrey Kolmogorov (1903-1987) described a mathematical relationship between the fluctuations in a flow’s speed and the rate at which its energy dissipates. 2️⃣the paint, at the smallest scale, mixes around with some background swirls and whirls in a fashion predicted by turbulence theory, following a statistical pattern known as Batchelor’s scaling. ℹ️Batchelor’s scaling mathematically represents how small particles (drifting algae in the ocean or pieces of dust in the wind) are passively mixed around by turbulent flow.
