Probably not an original thought, but at least an original image. Reading Michael Pollan’s A Place of my Own in which he reminds me of Thoreau’s description of his thin-walled cabin and connects it to American domestic architecture’s “centrifugalness.” The Lunar Lander’s skin was as thin as a few layers of mylar. It encloses an atmosphere in an inhospitable environment, but is perhaps the ultimate expression of Thoreau’s thinness.
