Zur einheitlichen Feldtheorie

de Albert Einstein · Publicada por primera vez en 1929

"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 field 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 this was still tentative; and soon he found he had to abandon it" (Hoffmann/Dukas, ''Albert Einstein: Creator and Rebel'' (1972) pp. 225-226).
