Waves and ripples in water, air, and æther : $b Being a course of Christmas lectures delivered at the Royal Institution of Great Britain
"Waves and Ripples in Water, Air, and Æther: Being a Course of Christmas Lectures Delivered at the Royal Institution of Great Britain" by J. A. Fleming is a scientific publication likely written in the early 20th century. The book serves as a collection of lectures intended to educate a wide audience about the various forms of wave motion that occur in different media—specifically in water, air, and the æther. Through experimental illustrations and clear explanations, it aims to demystify complex scientific concepts linked to waves and their practical implications, such as wireless telegraphy and sound. At the start of the text, the author introduces wave motion, describing familiar observations by the sea, such as how waves break upon the shore or how ripples expand from a disturbance in a pond. Fleming emphasizes the importance of understanding the properties of waves—whether in water, air, or the æther—by comparing them to each other and noting their common characteristics. He outlines fundamental questions about what constitutes a wave and the nature of wave motion, providing definitions and examples that set the stage for the detailed discussions and experiments to follow in the subsequent chapters.

Signalling across space without wires being a description of the work of Hertz & his successors
"Signalling across space without wires" by Sir Oliver Lodge is a scientific publication written in the late 19th century. The work primarily focuses on the groundbreaking experiments conducted by Heinrich Hertz and his successors, specifically concerning the generation and application of electromagnetic waves for wireless communication. Utilizing Hertz’s discoveries, Lodge explores the theoretical and experimental aspects of how electrical signals can be transmitted over distances without the need for physical wires. The opening of this book begins with notes from a lecture delivered by Lodge at the Royal Institution of Great Britain, where he reflects on Hertz’s significant contributions to the field of experimental physics. Lodge emphasizes Hertz’s tragic early death and the impact of his work, which validated Maxwell's theories on electromagnetic radiation. He introduces his intention to demonstrate some of Hertz's experiments while providing a foundational understanding of electrical waves and their implications for telegraphy. This introductory portion sets the stage for an in-depth exploration of the principles behind wireless communication, detailing early experiments that demonstrate the existence and nature of electromagnetic waves as they relate to practical applications in signaling.

Hertzian Wave Wireless Telegraphy
"Hertzian Wave Wireless Telegraphy" by Sir J. A. Fleming is a scientific publication written in the early 20th century. This work explores the principles and technical aspects of wireless telegraphy through electric waves, primarily focusing on the advancements made by figures such as Marconi. The book aims to provide a coherent understanding of how Hertzian waves function, their generation, transmission, and reception. The opening of the text establishes the importance and growing public interest in wireless telegraphy, driven in part by the innovations of Marconi. Fleming outlines the key topics he will discuss, including the scientific principles behind electric wave telegraphy. He highlights the challenges of communicating these complex ideas to a general audience, leading to a systematic examination of both the transmitting hardware and the underlying physics of electric waves and their behavior in the ether. By drawing parallels between electric and sound waves, he sets the stage for a detailed exploration of how electric waves can be generated and transmitted over great distances.
