內(nèi)容概要
This book is built up from a course of lectures given at the Physics Depart-ment of Florida State University and has the aim of presenting the indis-pensible material in a direct and concise form. It does not require previous knowledge beyond the basic ideas of special relativity and the handling of differentiations of field functions. It will enable the student to pass through the main obstacles of understanding general relativity with the minimum expenditure of time and trouble and to become qualified to continue more deeply into any specialized aspects of the subject that interest him.

章節(jié)摘錄
版權(quán)頁(yè):插圖:The conditions (a) and (b), which are needed for conservation of totalenergy and momentum, do not often apply in practical cases. They wouldapply if space were static outside a definite tubular region in four dimensions.This could be so if we had some masses which start to move at a certaintime, so that the motion creates a disturbance which travels outward withthe velocity of light. For the usual planetary system the motion will havebeen going on since the infinite past and the conditions do not apply. Aspecial treatment is needed to discuss the energy of the gravitational waves,and this will be given in Section 33.
