First Separate Edition. "In 1928, [Einstein] embarked on a new approach to a unified field theory . . . involving what he called 'distant parallelism'. . . . By early 1929 he had solved the main problems involved in writing down field equations for his unified theory. On the day of official publication of the third of a formidably technical series of nine articles on the theory . . . excited headlines appeared in foreign newspapers throughout the world. . . . In this frenzied, unscientific atmosphere, Einstein's new theory was hailed in the press as an outstanding scientific advance. Yet Einstein had stated in his article that it was still tentative; and soon he found he had to abandon it (Hoffman, Einstein, pp. 225-26).
