The math that describes the branching pattern of trees in nature also holds for trees depicted in art—and may even underlie ...

The scale invariance in branch diameter dictates how much smaller a limb should be as it branches and how much investment a ...

Leonardo da Vinci’s sketch of a tree illustrates the principle that combined thickness is preserved at different stages of ramification. The math that describes the branching pattern of trees in ...

This science of trees inspired my colleague and me to measure the scaling of tree branch diameter in art. Among my favorite images is a carving of a tree from a late-medieval mosque in India.
