This is a collection of essays which display the author's talent for bringing literary and scientific concerns into harmony. These meditations touch upon both the ethereal and the corporeal: the dependence of a ballerina on the laws of physics; the chice every scientist makes between tinkering and theorizing; the unscientific nature of discovery; the mystery of human flight without propellers; and the impulse behind the unprompted smile.
