Paper, 'On an apparatus for facilitating the reduction of tidal observations' by G H [George Howard] Darwin

Reference number: PP/20/23

Date: 1892

Description

Darwin writes: 'The tidal oscillation of the ocean may be represented as the sum of a number of simple harmonic waves which go through their periods approximately once, twice, thrice, four times in a mean solar day. But these simple harmonic waves may be regarded as being rigorously diurnal, semidiurnal, terdiurnal, and so forth, if the length of the day referred to be adapted to suit the particular wave under consideration.'

Annotations in pencil and ink. Includes two pages of geometrical figures relating to harmonic analysis.
