FIRST EDITION, monograph issue. Though presented as a separate publication, this is in fact an offprint from Annalen der Physik, 4. Folge, Band 49, 1916, and it is so identified on the verso of the title page. "Whereas Special Relativity had brought under one set of laws the electromagnetic world of Maxwell and Newtonian mechanics as far as they applied to bodies in uniform relative motion, the General Theory did the same thing for bodies with the accelerated relative motion epitomized in the acceleration of gravity. But first it had been necessary for Einstein to develop the true nature of gravity from his principle of equivalence ... Basically, he proposed that gravity was a function of matter itself and that its effects were transmitted between contiguous portions of space-time ... Where matter exists, so does energy; the greater the mass of matter involved, the greater the effect of the energy which can be transmitted. In addition, gravity affected light ... exactly as it affected material particles. Thus the universe which Newton had seen, and for which he had constructed his apparently impeccable mechanical laws, was not the real universe ... Einstein's paper gave not only a corrected picture of the universe but also a fresh set of mathematical laws by which its details could be described" (R.W. Clark, Einstein, New York, 1984, p. 253).
