To quickly assess the difficulty of the text, read a short excerpt:
Thus if a body moving uniformly is radiating energy, it is also losing momentum. The equation then indicates that there is a force acting on the body even though its velocity remains constant. It has sometimes been suggested as a parodox, that whereas ordinary electro-magnetic theory clearly indicates a resistance MINKO WSKPS FO UK-DIMENSION VECTORS 8 1 to the motion of a radiating body through the aether, 1 yet the Principle of Relativity must allow that a body radiating equally in all directi...ons must be capable of remaining in uniform motion through the aether if subject to no external force. The above analysis resolves the paradox ; it admits the resistance, but finds it to be equal to the rate at which mo- mentum is lost owing to the radiation of energy, even though the velocity be unchanged. This proposition of the momentum or inertia of energy is one which, in the development of mechanics subject to the Principle of Relativity, is universal. A familar instance is to be found in the mechanics of the free aether as ordinarily stated.
