Excerpt from Aberration: And Some Other Problems Connected With the Electromagnetic Field; One of the Two Essays to Which the Adams Prize Was Awarded in 1899, in the University of Cambridge
In 54 - 56 will be found a comparison of the theoretical stresses of 52, 53 with observations, chiefly on liquid media, made by Quincke and others. The agreement is in all cases as close as could be expected in View of the experimental difficulties.
In Part IV. We have tried to ascertain the possibility of explaining aberration on the hypothesis that the polarisation of material media is continuous, not molecular as is assumed in Part II. 19, 20.
In 57 it is shown that the velocity of light in a medium drifting with constant velocity a through a stationary ether is increased by an amount fin (k 1)/k. In 58 in order to obtain Fresnel's coefficient we are driven to assume that under these conditions the ether is dragged by the material medium with velocity a (k the ordi nary facts of aberration are then explained 59, for the directions of rays prove to be governed by the same laws as in the theory of Lorentz.

Paperback. Zustand: New. Print on Demand. This book investigates the relationship between the electromagnetic field and matter. The author explores a theory of the electromagnetic field consistent with modern interpretations of chemical, optical, and magnetic phenomena in terms of electrically charged particles. A particular case of such a theory was proven to explain the phenomenon of aberration in 1892 by H.A. Lorentz. This book extends Lorentz's work to a theory of the drifting medium where the ether is stationary and material media drift through it. The author finds that a medium which is isotropic when stationary behaves when drifting like a uniaxial crystal. The book includes investigations into the values of stresses in an electromagnetic field in accordance with several possible hypotheses, extending the work of Maxwell, Helmholtz, Kirchhoff, and Lorberg by considering neglected factors which appear to the author to be of some importance. The author concludes that their theory yields a system of stresses consistent with a fluid medium in equilibrium.
