“Mathematicians have made a crochet model of chaos – and are challenging anyone else to repeat the effort.”

“Imagine a leaf floating in a turbulent river and consider how it passes either to the left or to the right around a rock somewhere downstream.

“Those special leaves that end up clinging to the rock must have followed a very unique path in the water.

“Each stitch in the crochet pattern represents a single point – a leaf – that ends up at the rock.” (BBC via rebecca’s pocket)
