Excerpt from Electric Oscillations and Electric Waves: With Application to Radiotelegraphy and Incidental Application to Telephony and Optics This book is designed to present a mathematical treatment of some of the fundamentals of the theory of electric oscillations and electric waves. Although the selection of material particularly applicable to radiotelegraphy has been the first consideration, yet, because the electromagnetic theory, which is fundamental to radiotelegraphy, is fundamental also to optics, wire telephony and power transmission, it is hoped that the volume may be useful in these fields also. Book I on Electric Oscillations and Book II on Electric Waves are practically independent, so that a reader with a fair knowledge of mathematics may read the two books in either sequence. A student in optics might confine his attention almost entirely to Book II. A mature reader primarily interested in wire telephony or power transmission might begin at Chapter XVI of Book I, and continue through Chapter XVII, with such occasional references to the earlier chapters as are necessary for familiarity with the methods employed. He might then look into some of the earlier chapters in order to acquaint himself with the various transformer problems arising in connection with coupled circuits. It is suggested that students of radiotelegraphy begin at the beginning of Book I and read the various chapters consecutively, with the possible exception of Chapters IX, X, and XV, which may be omitted or postponed without rendering difficult the understanding of what follows. It is perhaps unnecessary to say that the theoretical work of this book should be supplemented by copious descriptive matter and laboratory work. Certain important subjects related to radiotelegraphy have been omitted - particularly the matter of spark-gaps, arcs, vacuum tubes, direction finders and the propagation of electric waves over the surface of the earth.
