Many of these patterns even resemble geometric shapes. One of the most common? Hexagons. Why do we see this six-sided shape occur so many times in nature? This week we explore why hexagons are so common in the natural world, from honeycomb to bubbles to rocks, and what their mathematics, physics, and biology may have in common. ----------- READ MORE: D’Arcy Wentworth Thompson.
