Sense of Scale

Is your head hurting yet? Five million times smaller. Our image is
beginning to look like a leaf with its delicate tracery of veins.
That's fitting, because a tree is a good example of the fractal
nature of Nature. Branches branch into smaller branches, which
themselves branch into yet smaller branches, all roughly similar to
any other branch on the tree. Same goes for the veins in a leaf.
