Excerpt from Works on Wireless Telegraphy and Allied Subjects
The Preface of a book is the place in which the Author makes his excuses for writing it, or his explanations of its scope and purpose. Following this practice, it may be mentioned that the writer published in 1902 a little book entitled "Waves and Ripples in Water, Air, and Æther, " through The Society for Promoting Christian Knowledge, which was a reprint, with some amplifications, of a Course of Christmas Lectures given at the Royal Institution, London. The last chapter of that book contains a brief reference to the then young art of radiotelegraphy. In the years that have since elapsed, this branch of telegraphy has developed with wonderful rapidity into a unique and most valuable means of communication. The importance of it is shown by the fact that three International Conventions and two Parliamentary Committees have deliberated at length on its regulation and condition within the short space of ten years. A large and highly technical literature has grown up around it, and an industry of considerable dimensions been created by it. Its astonishing achievements have raised a desire in the minds of the general public to know something of its mode of operation and possible future development, but in a form divested as far as possible of unexplained technicalities or abstruse formulæ. Many of the popular books written with this object seem to the writer to give insufficient explanations of the physical processes involved.
