...photographic plates no bigger than a stick of chewing gum, astronomers can look at a spectrum so tiny that it must be viewed through a jeweler's eyepiece and tell what kind of atoms are dancing in a star trillions of miles away. Thus has astronomy advanced since Galileo first glimpsed the four big satellites of Jupiter and wondered what they were. The mod ern art of splitting up light into its com ponent colors, which disclose the chemical nature of the source, depends on a little thing called the diffraction grating. This is a plate of glass...

There are also such incidents as the surprise appearance of large crowds to applaud private performances, and gum-chewing piano pounders telling outraged song birds to get hot, Toots, and compete with ladies who sing with their hips. These devices are strongly reminiscent of a young woman named Grace Moore, and it seems a shame that they should appear in a story with so great pportunities for pleasing...
