Text: Relativity reexamined. Prof. Brillouin maintains that general relativity may only be considered as an approximation and needs a thorough revision. He discusses many problems, both theoretical and experimental - how to measure gravity waves, their frequencies, their velocities and propagation when observations reach a power of one million times greater than today; the use of transverse waves; and how, with the use of a graser, scientists might determine whether the velocity of gravity waves actually equals the velocity of light. Topics include: Some problems about restricted relativity; Gravitation and relativity quantized atomic clocks; A badly needed distinction between mathematical sets of coordinates and physical frames of reference; Special relativity Doppler effect; Relativity and gravity; A gravistatic problem with spherical symmetry. New York: Academic Press, October 1970. 122 p.
