Paper, 'On the figure of equilibrium of a planet of heterogeneous density' by G H [George Howard] Darwin

Reference number: PP/4/11

Date: 1883

Description

Darwin writes: 'The problem of the figure of the Earth has, as far as I know, only received one solution, namely, that of Laplace. His solution involves an hypothesis as to the law of compressibility of the matter forming the planet, and a solution involving another law of compressibility seems of some interest, even although the results are not perhaps so conformable to the observed facts with regard to the earth as those of Laplace. The solution offered below was arrived at by an inverse method, namely, by the assumption of a form for the law of the internal density of the planet, and the subsequent determination of the law of compressibility. One case of the solution gives us constant compressibility, and another gives the case where the modulus of compressibility varies as the density, as with gas.'
