For the first time, a book of articles by Nikola Tesla, a famous inventor in the field of electrical and radio engineering, but at the same time, perhaps the most mysterious scientist of the late 19th and early 20th centuries, is being published in Russian. Most of the articles that made up the collection were published during Tesla’s lifetime in various newspapers and magazines in the United States, where he lived for many years. The reader becomes acquainted with the author’s amazing experiences and arguments, affecting almost all areas of human activity, in which an unconventional view of natural phenomena can be traced. N. Tesla left behind many secrets, which inquisitive minds have yet to penetrate. The book is intended for a wide range of readers.
