Pieces of Einstein’s 1905 Puzzle

Although I am flattered by the reference to me in Alex Harvey and Engelbert Schucking’s article, I need to correct the record. Sometime in the late 1970s, while giving a lecture at the University of Maryland, I innocently stated Einstein’s prediction about the polar and equatorial clocks. It had not occurred to me that the prediction was wrong. After the lecture Carroll O. Alley came up to me and pointed out the error. He also gave me some reprints in which he presents the correct theory and gives results that prove it with atomic clocks flown in airplanes. ¹ Alley is the hero of this tale and should be credited.
