Wireless - by P.J. Risdon, 1923, Ward, Lock & Co Ltd, London
A phenomenal book describing wireless technology as it already existed in 1923 including clear descriptions of the ether theory and Einstein's theory of relativity, and explaining how Einstein's theory may have been erroneously or intentionally used to erase the ether theory. Both theories remain unconfirmed even 100 years later. But the entire wireless technology fundamentals, including remote control of ships and aircraft was already in existence at that time, and this technology was based entirely on the ether theory. Exceptionally user-friendly book. Download
