In a revision of his doctoral dissertation for Princeton University (no date noted), Sweetnam details American physicist Henry Rowland's (1848-1901) invention of the diffraction grating, and the role of that instrument in the formation of a set of disciples, a school of physicists identified and defined by their use of it in analyzing optical phenomena. He assumes no scientific background. Annotation c. Book News, Inc., Portland, OR (booknews.com)
