Show MANY WORKED ON WIRELESS As Far Back as 1853 Lord Kelvin Was Experimenting with the Principle. Wireless telegraphy has many discoverers. dis-coverers. As has been so often the case In any branch of physics, whether wheth-er pure or applied, the name of Lord Kelvin is associated with the discovery. discov-ery. In 1853 he gave forth the theory of oscillation. In 1S65 Maxwell propounded pro-pounded the theory of electrical waves, and in 1888 Hertz practically discovered them. Sir Oliver Lodge was looking for the waves at the same time, and was successful In finding them running along wires in the same year that Hertz discovered them going through space. In 1890 he was able to take a further step, developing the receiving arrangements arrange-ments for the detection of these waves by means of the principle which he decided to call syntony. At the same time another word, coherer, was added to the language. In 1894 he was able to give a demonstration demon-stration before the British association of signaling across space without wires, and about the same time he published a book. In 1895 Admiral Popoff of the Rus-t Rus-t sian navy and Capt. Jackson of the English navy carried the idea a little further, and then in 1896 Marconi took up the matter with great pertinacity and marked success. |
