TO THE READERSThe book you are holding in your hands is not a story with “resurrections” and “rebirths”. This is the story of a real person's life in the real world. But for a modern young reader it may seem truly “otherworldly.” The life path of our hero from a Russian submarine officer, later a Red Navy man, to an outstanding Soviet scientist occurred in the years when our homeland, overcoming incredible difficulties, turned into a powerful world power - the Union of Soviet Socialist Republics. The curtain of time separating present-day Russia from the country whose heir it is is not so great. But it is difficult for an unbiased look to break through the heap of facts and speculation, frantic denunciation and equally frantic glorification of our recent past. The life story of Axel Ivanovich Berg, a fast, intense life, very accurately reflects all the drama of that harsh but heroic era. An era that left us a great country with great science, one of the creators of which was A.I. Berg. The book itself, written during the hero’s lifetime, bears the imprint of time. The author of the book, the famous writer Irina Lvovna Radunskaya, managed to convey its rhythm and the feeling of unstoppable movement well. Forward! Do not stop! Keep up! One can’t help but remember lines from songs from the breakthrough era: Hello, country of heroes! Country of dreamers, country of scientists!.. Our minds gave us steel arms and wings, And instead of a heart, a fiery motor!
