This report gives the results of pressure-distribution tests made to study the effects on lateral stability of changing the span-load distribution on a rectangular monoplane wing model of fairly thick section. Three methods of changing the distribution were employed: variation in profile along the s

โฆ Synopsis
of light, the work of Roemer, Bradley, Fizeau, Cornu, and Foucault is examined fully. The evolution of the theory of interference of luminous waves is woven about the work of Newton, Young and Fresnel. The phenomena of diffraction are dominated by the principle of Huyghens and again by Newton, Fresnel and Cornu, and in later investigations, Fraunhofer, Rutherford, Rowland and Fabry and Perot. On the applications of interference the work of Michelson and that of Fabry and Perot are naturally given important consideration. The D6ppler principle as applied to light propagation, the early work of Fresnel and the relatively recent classics of Michelson and Morley and Lorentz are examined critically, and then follows a lengthy chapter on the elusive subject of relativity. Polarization, double refraction, elliptic and circular polarization, chromatic polarization and rotary polarization are most fully analyzed. We are again brought into the field of recent activity with spectrum analysis, absorption spectra, Zeeman effect, aetinometry, and the methods of color photography of Lippman and Lumiere. A further advance into this territory is made with a consideration of the infra-red spectrum, phosphorescence, Raman effect, black body radiation, radioactivity, optics of x-rays and photo-electric effect.
The work is a remarkably well correlated and comprehensive collection of the phenomena of physics treated with rare lucidity by methods of the mathematical physicist.
