I have been studying the Dunning-Kruger Effect, which proposes those (we, me) of little knowledge claim to know a lot. Socrates provided this preface: "Only true wisdom is knowing how little you know." Then, after a moment of 2000+ years, Darwin chimed in with: "Ignorance frequently begets more confidence than knowledge does." Here is a helpfully instructive (or not) Normaphoto:It is a hummingbird flying into a fountain plume. He is only an inch or two long and weighs nothing. Unlike our local peccadilloes which, like their southern relatives, armadillos, are armored, hummingbirds have no protection against liquid missiles that weigh more than they do. Yet they fly out hydrated and unharmed. I have no idea how they manage that. I see it happen. Norma photos it. Still, I don't know how it's done. Behind this lens, focused on an endless moment of the universe, I feel less than knowledgeable and more like a clumsy contortionist who has stepped on his own head --hate when that happens.
