A novel about creativity. How does it (creativity) arise, and how through creativity a person comes to his main question (I think everyone has a main question). My favorite writers once tried to answer the main question: Dostoevsky, Bulgakov, Strugatsky. I call this novel realistic because all the events, scientific discoveries and names of famous scientists in it are genuine, taken from real life, but here are the explanations for these events I give unusual, sometimes mystical and sci-fi. I almost always highlight such places in the text in italics.
