"This is the most important result obtained in connection with the
theory of gravitation since Newton's day. Einstein's reasoning is
the result of one of the highest achievements of human thought."--Sir
J. J. Thomson, president of the British Royal Society and professor
of physics at the University of Cambridge.
"It surpasses in boldness everything previously suggested in
speculative natural philosophy and even in the philosophical theories
of knowledge. The revolution introduced into the physical conceptions
of the world is only to be compared in extent and depth with that
brought about by the introduction of the Copernican system of the
universe."--Prof. Max Planck, professor of physics at the University
of Berlin and winner of the Nobel Prize.
