Chapter I Introduction	1
SECTION I
Chapter II Historical survey	6
Astronomical aberration of light: Bradley's guiding ideas. Optical refraction uninfluenced by the Earth's motion: Fresnel's explanation. Aberration as measured by a water-telescope. Theoretical views of Cauchy. Views of Sir George Stokes as to constitution of the aether: suggested partial analogy of material substances like pitch; irrotational viscous motion unstable, also involves dissipation of energy: irrotational character of finite motions of the aether explained by its high rigidity or rotational elasticity. Maxwell's formulation of Fresnel's theory. The general absence of any optical influence of the Earth's motion suggests that the aether may move along with the Earth: the difficulties of this mode of explanation. Maxwell's discussion of electrodynamic theory relative to moving bodies. Introduction of atomic electric charges into the aether theory. Aether stagnant. Alleged difficulties of the electric theory. Maxwell's original scheme effective for systems at rest: nature of its adaptation to moving systems. A constitutive aether affords the only explanation of an atomic constitution of matter: the various atomic theories: electric aspect of an atom. MacCullagh's optical aether is the electric aether. Molecules may be systems of electrons: the duality of positive and negative dynamically necessary. Maxwell's elimination of ' electricity ' from the theory is available for ordinary electrodynamics, but cannot be extended to problems involving radiation.
Chapter III General kinematic theory of optical rays in moving media	30
Specification of a ray: ray-velocity: wave-velocity: wave-front: principle of Least Time: application to a moving medium. Theories of aberration: if the aether moves sensibly its motion must be irrot- Page:Aether and Matter, 1900.djvu/24 Page:Aether and Matter, 1900.djvu/25 Page:Aether and Matter, 1900.djvu/26 Page:Aether and Matter, 1900.djvu/27 Page:Aether and Matter, 1900.djvu/28 Page:Aether and Matter, 1900.djvu/29 Page:Aether and Matter, 1900.djvu/30 vibrations of the molecular system: the methods of dynamics of particles adequate to the problem: the system referred to rotational coordinates; the condition for circular principal vibrations. Any purely constitutive potential energy for the molecule leads to the Zeeman phenomena, with the requisite generality. Inference as to effective isotropy of the molecule. The Faraday effect and Becquerel's law of dispersion deduced from the Zeeman effect when the freely mobile electrons are all negative; or when the dispersion is controlled by one absorption band, or by several bands for which the Zeeman constant is the same. Optical rotations necessarily of dispersional type; and therefore not simply related to material structure. Direct kinematic analysis of optical rotations for crystalline media, b y reference to rotating frame: law of rotation in different directions: the permanent types of vibration when rotation is superposed on double refraction: problem of refraction into a chiral medium not determinate.
