THE INDIANAPOLIS TIMES _MOVESBACKWARD,P4SCIENCE VIEWFlight Forward or OppositeWith Equal Facility,Newest Theory./?;/ United PressNEW YORK, April 19.—“Two way” time—time which moves backward or forward with equal facility—exists in physics and chemistry, according to a revolutionary theory proposed by Dr. Gilbert N. Lewis of the University of California.Dr. Lewis, who, with Dr. J. Mc-Keen Cattell. • psychologist, Thursday night received the 1930 gold medal of the Society of Arts and Sciences, advanced h:s theory in a paper read to the society.The new theory boldly banishes the thought of time moving in only one direction.Illustrative of 1 is new theory of “two way” time, it was suggested that it was conceivable that events of today are among the factors which caused Caesar about 2,000 years ago to cross the Rubicon.Lewis offered no direct proof of this thesis, but it was offered by way of clarifying the idea that there is no positive future or past, but that one exerts a “pull” on the other.Under his theory there would be rejected the idea that yesterday preceded today in any absolute sense.“The concept of time moving in one direction is forced upon us by the phenomena of our own consciousness and memory,” the paper said.“Yet if we should construct a moving picture to represent the motions of the solar system it would be just as satisfactory if it were runbackward. And the Newtonian laws would be equally w’ell obeyed.”Dr. Lew'is agreed with the recently expressed theory of Dr. Robert A. Millikan of the California Institute of Technoloby, that the world is enduring, not undergoing a process of gradual destruction.
