Description

Patersons Worms Worms eat sediment, delineating some sort of path. The 21 November 1969 issue of Science had computer simulations of a few of these worms, in comparison with various fossilized tracks.

Mike Paterson studied these worms, a type of 2D Turing Machine, on an isometric grid. This notebook has more history on these, along with Mathematica code for producing the trails these worms leave behind.
