...ether. Einstein incorporated the theory in the Relativity structure, as a consequence not of absolute motion but of relative motion-that is, of the clock's motion relative to a hypothetical observer. For a long time there was no experimental confirmation of the Larmor-Lorentz-Fitzgerald slowdown. Then, about two years ago, Dr. Ives used glowing particles of hydrogen gas as "atomic clocks," showed that their rate of oscillation slows down when the particles themselves are speeded up to velocities around 1,000 miles a second (TIME, May 9, 1938). The experiment was spectacular but the conclusion ambiguous...
