Contends that it is feasible to perform astronomical observations which could provide an experimental basis for choosing between the two points of view expressed in the various discussions of the subject.
A brief comment on the clock paradox controversy in which the author suggests "a trivially simple derivation of the time relation" and claims that "since the observers are not equivalent, there is no paradox."
In Spanish. Not examined.
"The field is first obtained for a particle moving uniformly relative to an inertial frame, and then generalized on the assumption that it is independent of the acceleration of the particle. The potentials, expressed in terms of retarded position and velocity 4-vectors, have the form m(2vivj-ηij)/|p|, where ηij is the metric tensor for flat space-time." Sci. Abs. 56A:594, 1953.
An article based on thoughts expressed by G. Crocco in the Italian magazine, Civilta Delle Macchine. He seeks an application of the relativistic theory to applied cosmonautics.
Letters referring to correspondence between McCrea and Dingle appearing in Nature. There the latter named men disputed the truth of the statement which appeared in Sir George Thomson's book, "The Foreseeable Future." This said that a person who ventured out from the earth for a long journey in a space-ship would find, when he returned after several years, that he had aged less than the people who had stayed at home. In other words, space travel might be a way of putting off old age.
The empirical result of Michelson and Morley is symbolized in the behavior of a spherical light wave inside a rigid spherical
