summary:
  It is a case of an advance arrived at by pure theory: the whole effect of Einstein's work is to make physics more philosophical (in a good sense), and to restore some of that intellectual unity which belonged to the great scientific systems of the seventeenth and eighteenth centuries, but which was lost through increasing specialization and the overwhelming mass of detailed knowledge. Dr. Einstein propounded his theory nearly fifteen years ago.

summary:
  In this way, by using as stepping-stones the practice in thinking and visualisation which Euclidean geometry gives us, we have acquired a mental picture of spherical geometry. Recapitulating, we may say that according to the general theory of relativity space is endowed with physical qualities; in this sense, therefore, there exists an ether.

  From NEWTON to EINSTEIN Changing Conceptions of THE UNIVERSE BY BENJAMIN HARROW, Ph.D. SECOND EDITION, REVISED AND ENLARGED With Articles by Prof. Einstein, Prof. J. S. Ames (Johns Hopkins), Sir Frank Dyson (Astronomer Royal), Prof. A. S. Eddington (Cambridge) and Sir J. J. Thomson (President of the Royal Society) Portraits and Illustrations NEW YORK D. VAN NOSTRAND COMPANY Eight Warren Street 1920 PREFACE Einstein's contributions to our ideas of time and space, and to our knowledge of the universe in general, are of so momentous a nature, that they easily take their place among the two or three greatest achievements of the twentieth century. I wish to take this opportunity of thanking Prof. Einstein, Prof. A. A. Michelson of the University of Chicago, Prof. J. S. Ames of Johns Hopkins University, and Professor G. B. Pegram of Columbia University for help in various ways which they were good enough to extend to me.

  Einstein's Theories of Relativity and Gravitation A selection of material from the essays submitted in the competition for the Eugene Higgins prize of $5,000

summary:
  Now in Newtonian mechanics, absolute space and absolute time and force and inertia and all the other apparatus, altogether imperceptible, appearing only at the proper time to make possible a proper building up of the theory, play the same mysterious part as the ideas order and regularity in my story. TAKING THE BULL BY THE HORNS The hypothesis of relativity asserts that there can be no such concept as absolute position, absolute motion, absolute time; that space and time are inter-dependent, not independent; that everything is relative to something else.
