This effect was first experimentally verified when Ives and Stilwell observed the exact decrease in frequency predicted by the transverse Doppler effect. This effect is most often illustrated by considering a traveler who moves at relativistic speeds and returns to find that he is (*) younger than his twin, a result known as the "twin paradox." It was verified at non-relativistic speeds by placing four atomic clocks on planes and seeing what time they read compared to a stationary one. For 10 points, name this effect which, like length contraction, is predicted by special relativity.
