...effect well with his laws of gravity. Albert Einstein did better with his general theory of relativity. He found a metric (a measure) with which he could subdivide practically everything that happened in his fourth dimensional world. It was a theoretical measuring unit invented by Georg F. B. Riemann (1826-66), mathematician...

...Riemann metric subdivides time, space, undulations, tensions and the other simplest phenomena of the world. By multiplying that unit as though it were (crudely) pounds, gives the force of gravity between, say, the earth and the man or egg falling from the airplane. Gravity is thus not unique as Newton believed. It is a part of the world's pervasive unity. Again Dr. Einstein's suspicion brought him to perception. This...

...relativity did not account was electromagnetism. Dr. Einstein in 1905 had shown that electricity and magnetism were different aspects of one world activity. In 1919 he showed that gravity was another world activity. It was impossible, he believed, that gravity and electro-magnetism were two distinct world activities. His Riemann metric must be inaccurate...

Working in his Berlin study, musing in his sailboat on Wannsee, lolling in his beach chair at Luebeck, Albert Einstein figured out a new metric. It lies between Euclid's and Riemann's conceptions. It shows that gravity, electricity, magnetism. everything is a logical, not chance, part of the world. It enabled him last week to phrase in mathematical terms a theory by which "everything in the world" can be explained...
