    "abstract": "The relativistic conservation law involving the center of energy is reviewed\nand illustrated using simple examples from classical electromagnetic theory. It\nis emphasized that this conservation law is parallel to the conservation laws\nfor energy, linear momentum, and energy, in arising from the generators of the\nPoincare group for electromagnetic theory; yet this relativistic law reflecting\nthe continuous flow of energy goes virtually unmentioned in the text books. The\nillustrations here present situations both where external forces are present\nand are absent. The cases of a parallel plate capacitor, a flattened slip-joint\nsolenoid, and two interacting charges are included.",
