Substituting a fine Flickr image from the Wellcome Library London for the image I want but probably should not steal (a drawing by Crick of the DNA double helix) I suddenly realized something orthogonal to my original point.
1. Point of Crick’s drawing of double helix, shown in conjunction with a lot of his other lab notes and scribbles of molecular structures, diffraction patterns, etc. — making pictures of things lets us see structure instead of chaos.
2. Orthogonal point made by constellation image: making pictures of things lets us see structure that isn’t there!
One more thing I love about the Wellcome Library besides their wonderful slideshow: they have a copy of my science joke book in their History of Medicine collection.
