     Studies in biology and cognitive science point to biological processes that appear to be mathematically oriented — there are cells in our visual system that are sensitive only to vertical structures, our perception of distance arises from the geometry of binocular vision and our early learning seems based on calculating probabilities. The body is built to create structure from sensory data — to weave it into the objects we perceive.
