A work colleague had a few hours between flights last week so he took a drive to the Alder Planetarium in Chicago. During the show the narrator brought up something that he thought was rather intriguing. He showed some figures that compare the structure of the universe to the structure on brain neurons. http://sprott.physics.wisc.edu/pickover/pc/brain-universe.html We certainly live in an "Elegant Universe". Clear skies, Dale.
