Creative commons – flickr – Florida Memory: View of the Blue Hole swiming area at Florida Caverns State Park
I sometimes recall an article by Jerry Fodor in, I think, the New York Review of Books where he asked himself (something like) “I could be out on a lake in my boat, why am I bothering to discuss modularity?”
I then think about the swimming spot I visited last summer, near Durango (Colorado), cold clear ice melt and hot (I mean 35+C) weather.
I found this picture on flickr and it shows the nearest approximation I found to the inviting quality of that remembered swimming in Colorado.
Anyway, let’s talk next about scatterplots again, but raise the level a bit and get into scatterplot matrices.
