  "body": "\n## Summary\n\nA coupled map lattice is a [[dynamical system|BBZP1R872N]] with discrete time, discrete space and continuous state.\nAt each site of a lattice sits a real variable.\nIt is updated by a nonlinear map such as the [[logistic map|QN9X9BNKTX]] and then mixed with the values at neighbouring sites.\nCoupled map lattices were introduced by Kunihiko Kaneko in the 1980s as simple models of spatiotemporal chaos, turbulence and pattern formation.\nThey show a rich variety of behaviour, such as frozen patterns, travelling defects and fully developed spatiotemporal chaos.\n\n## Explanations\n\n### L1 human\n\nThink of a row of cells, each holding a number.\nAt every tick of a clock, each cell first applies the same simple rule to its own number, and then averages a little with its two neighbours.\nWith a chaotic rule, each cell alone would behave erratically; the coupling makes the whole row form patterns that move, merge and break up.\nIt is a toy model for systems like a turbulent fluid, where chaos happens in space as well as in time.\n",
