Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1920 edition. Excerpt: ...of the dynamical wave theory, which now is shown to explain all the known phenomena of the tides in every ocean of the globe. (6) And as this wave theory explains the eddies on known hydrodynamical principles, this triumph gives a vastly increased probability to Laplace's theory of the tides, in which we treat the waters, not only as in motion but also as oscillating in periods coperiodic with the forces which disturb the sea. (c) As the Harris-Sterneck eddies are shown to be generally contrary to pure mathematical theory for free waves in the two terrestrial hemispheres the theory of the tides as local phenomena utterly collapses and disappears from the sight of philosophers. IX. An Outline of the Newcomb-Hough Theory of the Yielding of the Earth's Solid Mass in the Variation of Latitude We come now to the presentation of an outline of the theory suggested by Prof. Simon Newcomb ("Monthly Notices," Roy. Astron. Soc., March, 1892) for accounting for the prolongation of the observed variation of latitude, from the 305 days given by the Eulerian cycle to the 427-day period found by Chandler. The ingenious theory put forth by Newcomb was to the effect that the prolongation of the theoretical Eulerian period is due to the yielding of the earth's mass under the imperfect rigidity of the terrestrial spheroid. The rigidity of the earth had been much discussed by Lord Kelvin and Sir George Darwin during the preceding 30 years in connection with tidal investigations, especially of the long-period tides. An observed failure of the long-period tide to develop, according to theory, was considered the most promising criterion to afford some definite physical indication of a gradual yielding of the external figure of the globe, which would...show more
