Recent Technical Developments in Radio
Arthur E. Kennelly · The Annals of the American Academy of Political and Social Science · 1929
RADIO communication has already exerted astonishingly great influences upon human affairs. Nevertheless, this influence has only recently become active, and it is probable that it will be still more marked in the future. In particular, the basic science of electro-magnetic waves, and the dependent applied science or technic of radio-communication, have been undergoing rapid development in recent years. Their effects on the world are likely to be very notable as time goes on. This article aims at presenting to non-technical readers, an outline sketch of recent technical developments. From this rough picture it may be possible to form some idea of not only what has already been technically accomplished, but also what may be coming through the picture in the near future, as time brings out the colors on the canvas. We can only expect to see but a little way into the forward scheme of things; because new discoveries and inventions may completely change both plans and progress.
