Electric Waves and their Application toW ireless Telegraphy which for several years have been given by the author to classes at Harvard University. In giving the lectures and in preparing this volume, the design has been: First, to present, in as elementary a form as possible, the course of reasoning and experimentation that has led to the conception of electric waves; second, to follow this with a discussion of the properties of electric waves and electric oscillations; third, to give a history of the application of electric waves to wireless telegraphy; and fourth, to elaborate the general principles and methods of electric-wave telegraphy in sufficient detail to be of possible use to elementary students of electricity and to amateur and professional electricians engaged in operating and constructing wireless telegraphic apparatus. The author wishes to express his sincere thanks to Commander S. S. Robison of the United States Navy, toM r. Elliott Woods of Washington, and to Chief Inspector D. M. Mahood of theN ew York Navy Yard for their kindness in supplying photographs for some of the illustrations. A lso, the author is grateful to theE ditors of the Physical Review for the loan of Plates I and II, and toM r. Greenleaf Whittier Pickard for the privilege of consulting his manuscript account of experiments on the effects of daylight on transmission. Finally, the author takes great pleasure in expressing his gratitude to his friend Mr. George Francis A rnold, who has kindly read the proofs and made many valuable suggestions. G. W. PIERCE.

Paperback. Etat : New. Print on Demand. This book takes readers on an electrifying journey through the world of electricity and magnetism, unveiling the fascinating relationship between these seemingly distinct forces. Beginning with the fundamental theories of electricity, the author delves into the intriguing concept of electric oscillations, a phenomenon first observed by Joseph Henry in the mid-19th century. Through meticulous experimentation and mathematical reasoning, scientists like Lord Kelvin and James Clerk Maxwell expanded upon these early discoveries, laying the groundwork for the modern understanding of electric waves. The book explores the historical development of key concepts like self-induction and electrostatic capacity, highlighting the critical role they play in generating and transmitting electric waves. With captivating explanations and insightful analogies, the author demystifies the science behind electric waves, providing readers with a comprehensive grasp of their properties, propagation, and potential applications, which will ultimately culminate in a fascinating exploration of the principles behind wireless telegraphy. The book's historical lens allows us to appreciate the enduring impact of these pioneering scientific discoveries, paving the way for the communication technologies we rely on today.
