GUIDES // THE MATHS
The maths behind the posters
Plain-English guides to the maths our posters are drawn from: the equations, the history and how each picture is computed.
Guide // Chaos theory What is a strange attractor?
A strange attractor is the shape chaos settles into. A plain-English guide to the Lorenz, Thomas and Clifford attractors, with their equations.
