1. The purpose of the expeditions was to determine what effect, if any, is produced by a gravitational field on the path of a ray of light traversing it. Apart from possible surprises, there appeared… Expand

AS a subject progresses the attractive simplicity of the early researches gives place to laborious elaboration. In the last three years, Dr. Chandrasekhar has been very active in the mathematical… Expand

IT is difficult to answer Sir James Jeans within the space of a letter; but I will begin with his statement (c). This is simply a statement of fact. Except in cosmological investigations,… Expand

IN Whitehead's theory of gravitation, as in Einstein's, the tracks of particles in a gravitational field are determined by the condition that a certain integral taken along the track is stationary.… Expand
