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.
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.
