An Italian gentleman residing in Boston announced that he had invented a perpetual motion machine, but a committee of government physicists showed him his error...
...University of Arizona, who explains away most of the canals by giving them a psychological origin in the sensory apparatus of the observer. Professor E. S. Morse writes interestingly of "What the Martians Might Say of Us," reversing in imagination the direction of the telescope. Mr. Nikola Tesla is thoroughly characteristic in the firmness of his belief that we shall soon be signalling to Mars by electricity...
...future of the method seems to lie in the application of currents of high frequency and very great electromotive force, such as one obtains by the use of the Thomson or Tesla coil and by the use of only one terminal. In this way the breakage of the tubes can be prevented...
...resistance of the primary of this coil is one-tenth of an ohm, and of the secondary 6000 ohms. The current through the primary was not stronger than 15 ampheres. The current from the secondary of the first coil was sent through the primary of 25 turns of a Tesla induction coil, the secondary of which has 500 turns. The secondary will give a spark through about six inches of air. Its terminals were connected with the electrofloe of the Crooke's tube already mentioned...
