Many natural systems spontaneously self organize into surprisingly ordered structures, even though they are driven far from equilibrium. Order often appears "for free" without any obvious pre-existing template. Regular patterns in space emerge, for example, as stripes on zebras, ripples on windblown sand, waves on coffee in a shaken cup, coloured sand that spontaneously un-mixes itself, wrinkles on icicles, or as weird columns that form in cooling lava flows. In his talk, Stephen Morris discusses the physics behind such non-linear patterns, and carries out live demonstrations.
