Hertzian Wave Wireless Telegraphy

"Hertzian Wave Wireless Telegraphy" by J. A. (John Ambrose) Fleming is a scientific text that explains the technology of early wireless communication through electric waves, with a focus on the pioneering work of inventors like Marconi. It aims to clearly explain the science behind how these waves are made, sent, and received, connecting scientific principles with telegraph technology. The book starts by noting the public's fascination with wireless communication, driven by new inventions. Fleming promises to cover important areas, such as the physics of electric wave telegraphy. He points out the difficulty of explaining these technical ideas to everyone, planning to look closely at both the equipment used to transmit signals and the physics of how electric waves work. By showing similarities between electric waves and sound waves, Fleming prepares the reader for a complete examination of how electric waves are created and sent across long distances.
