Lord Rayleigh

How does a country aristocrat become one of the defining physicists of his age? Terada Torahiko follows Lord Rayleigh from a fragile childhood and Cambridge examinations to a private laboratory, a Nobel Prize and a lifetime of exacting inquiry. Family memories, improvised apparatus and quiet humor bring the scientist’s daily world into view.

Sound, the blue of the sky, electrical measurement and the discovery of argon appear alongside farming, public responsibilities and the pleasures of research pursued for its own sake. Terada is especially interested in how character and surroundings shape scientific work, and in the marriage of intellectual independence with practical experiment.
