Page 45 - The council is neither a large operating scientific laboratory nor a repository of large funds to be given away to scattered scientific workers or institutions. It is rather an organization which while clearly recognizing the unique value of individual work, hopes especially to help bring together scattered work and workers and to assist in coordinating in some measure scientific attack in America on large problems...
Page 53 - No mere rotation of a bar-magnet on its axis produces any inductive effects on circuits exterior to it. The system of power about the magnet must not be considered as revolving with the magnet any more than the rays of light which emanate from the sun are supposed to revolve with the sun. The magnet may even, in certain cases, be considered as revolving amongst its own forces, and producing a full electric effect sensible at the galvanometer.
