Abstract
IN the Proceedings of the Wireless Section of the Institution of Electrical Engineers of June there is a review of the progress made in radio-telegraphy and telephony during the last few years by C. E. Rickard of Marconi's Wireless Co., Ltd. As this period has been notable for steady advance rather than outstanding invention, he was faced with two main problems (1) where to start and where to finish in relating this progress, and (2) what relative importance to attach to the numerous branches and ramifications which together make up the science, art and practice which provide the subject-matter of such a review. Progress in the science of radio covers advances of knowledge in theory and technique, but progress in the art, although dependent on progress in the science, also depends largely upon the commercial application of such improvements as may have been made in the past. In addition, the commercial aspect of progress in the art of radio, although mainly controlled by economics, is also governed by the application of international regulations in the practice of radio communication. Seeing that a new international agreement has recently been reached at Cairo, the occasion to discuss the effects of the 1938 convention is opportune.
