The book “On wireless telegraphy” by Alexander Stepanovich Popov is not just a scientific work, but a real milestone in the history of science and technology, which opened new horizons in the field of communication. Popov, as one of the founders of radio communication, immerses the reader in a world where science and technology intersect with human ambitions and dreams of free communication. This book will be a real find for anyone interested in the history of technology, radio technology and the development of communications. In his work, Popov shares his observations and discoveries in the field of wireless signal transmission. He describes not only the technical aspects of radio transmitters and receivers, but also philosophical reflections on how these technologies can change society. Readers will find that behind every scientific discovery is not only complex mathematics and physics, but also a passion for knowledge, a desire for progress and a desire to make the world more connected. The book will be of interest to a wide range of readers: from students of technical universities and specialists in the field of radio engineering to historians of science and just fans of technology. The age of readers does not matter both younger and more mature people will find inspiration and new ideas in it. The topics raised in the book are still relevant today: communication, innovation, the impact of technology on society - all this remains the focus of the modern world. Popov does not just state the facts, he creates a fascinating narrative that captures from the first pages. His writing style is clear and accessible, which allows even those who are not experts in the field of radio engineering to easily absorb material. The author masterfully combines technical details with live examples from his practice, which makes reading not only informative, but also fascinating. Topics that Popov raises range from the basics of radio communication to its social impact. He asks: how has wireless telegraphy changed people's lives? What prospects open up for humanity with the development of new technologies? These reflections make the book relevant today, when we observe the rapid development of communication technologies. Do not forget that “On wireless telegraphy” is not the only work of Popov. He is also known for his work in physics and electrical engineering, which has left a noticeable mark in the scientific community. Its contribution to the development of radio communication cannot be overstated, and this book serves as an excellent
