An Explanation Of Wireless Telegraphy, Cunard Line, 1904
Abstract: At the start of the 20th century whereas Henri Poincar\’e (1854-1912) was already deeply concerned in the developments of wireless telegraphy, he was invited, in 1908, to offer a collection of lectures on the \’Ecole Sup\’erieure des Postes et T\’el\’egraphes (today Sup’T\’elecom). Within the last part of his presentation he established that the required situation for the existence of a stable regime of maintained oscillations in a tool of radio engineering fully analogous to the triode: the singing arc, is the presence within the part airplane of steady limit cycle. The intention of this work is to show that the correspondence highlighted by Andronov between the periodic solution of a non-linear second order differential equation and Poincar\’e’s concept of restrict cycle has been carried out by Poincar\’e himself, twenty years earlier than in these forgotten conferences of 1908.
