A sequence of high-speed images of the formation of water droplets using 'the singing jet'.

Presented by the photographer to Charles Vernon Boys. Inscribed in ink, verso: 'To Sir Charles Vernon Boys with my compliments John J Hopfield 1935'.

The image was inspired in part by the chapter ‘Liquid cylinders and jets’; in the book Soap bubbles: their colours and the forces which mould them, by Charles Vernon Boys (London, SPCK, 1912). Boys described the effects of noises of different pitches on water jets and fountains containing very small water droplets.

Sir Charles Vernon Boys (1855-1944) British physicist and inventor, was elected a Fellow of the Royal Society in 1888.

John Joseph Hopfield (1891-1953) Polish-American physicist and spectroscopist, employed at the Libby-Owens-Ford glass company in Toledo Ohio, USA.
