In the gigantic conceptions of Einstein, the velocity of light-186,000 miles per second-dominates the whole Theory of Relativity. He proves mathematically that the velocity of light is, so far as man’s finite mind is concerned, the only CONSTANT in a universe of unstayable flux. On the sole absolute of light-velocity depend all human standards of time and space. Not abstractly eternal as hitherto considered, time and space are relative and finite factors, deriving their measurement validity only in reference to the yardstick of light-velocity. In joining space as a dimensional relativity, time has surrendered age-old claims to a changeless value. Time is now stripped to its rightful nature-a simple essence of ambiguity! With a few equational strokes of his pen, Einstein has banished from the cosmos every fixed reality except that of light. In a later development, his Unified Field Theory, the great physicist embodies in one mathematical formula the laws of gravitation and of electromagnetism. Reducing the cosmical structure to variations on a single law, Einstein {FN30-4} reaches across the ages to the rishis who proclaimed a sole texture of creation-that of a protean MAYA. On the epochal Theory of Relativity have arisen the mathematical possibilities of exploring the ultimate atom. Great scientists are now boldly asserting not only that the atom is energy rather than matter, but that atomic energy is essentially mind-stuff. “The frank realization that physical science is concerned with a world of shadows is one of the most significant advances,” Sir Arthur Stanley Eddington writes in THE NATURE OF THE PHYSICAL WORLD. “In the world of physics we watch a shadowgraph performance of the drama of familiar life. The shadow of my elbow rests on the shadow table as the shadow ink flows over the shadow paper. It is all symbolic, and as a symbol the physicist leaves it. Then comes the alchemist Mind who transmutes the symbols. . . . To put the conclusion crudely, the stuff of the world is mind-stuff. . . . The realistic matter and fields of force of former physical theory are altogether irrelevant except in so far as the mind-stuff has itself spun these imaginings. . . . The external world has thus become a world of shadows. In removing our illusions we have removed the substance, for indeed we have seen that substance is one of the greatest of our illusions.” With the recent discovery of the electron microscope came definite proof of the light-essence of atoms and of the inescapable duality of nature. THE NEW YORK TIMES gave the following report of a 1937 demonstration of the electron microscope before a meeting of the American Association for the Advancement of Science:
