Particularly fascinating was Kaku's account of the state of physics in the decade prior to 1905, when Einstein's Special Theory of Relativity set the discipline in a new direction.
When nineteenth-century physicists learned that light traveled through space in waves, they assumed that the waves must travel in a medium, just as ocean waves travel in water. Physicists called this hypothetical medium "ether," and, according to Kaku, attributed . . .
