Lunar Eclipses,The geometrical conditions of a lunar eclipse are given by the two cones formed through the common tangents interior and exterior to the Sun and the Earth (Fig. 1.1.1). At the distance of the Moon these cones give with the plane normal to the axis Sun-Earth two circular intersections named the ..

Eclipse Phenomena in Radio Astronomy, numerous analogies of the optical phenomena including the eclipses and occultations of radio sources. In these phenomena the optical refraction is replaced by the electronic refraction whose existence is conditioned by the ionised medium, for instance, the ionosphere. The radio waves traversing suc

,Einstein’s Deflection of Light,sequences such as the formation of images and the modification of light intensity. The lunar eclipse theory was, therefore, for us the starting point of a general investigation of this problem . It was also the first correct treatment of the photometrical side and the most general examination of

The Regulatory Response to Globalized Free-Market Capitalist Competition, and the Free Rider Strategy as Antithetical to Technological Innovation and Education,bled advanced economies to pay wages sufficient to defer or ameliorate crises of overproduction. However, technological development also facilitated the free flow of technological information and expertise, rendering such advantages increasingly problematic and transient. Consequently, capitalists h
