A book published about 30 years ago, it would seem, few people can be interested - life has gone ahead, progress in science and technology is evident. Only in recent years have we witnessed amazing discoveries! However, an inquisitive person is interested not only in the result, but also in the path to the goal: what they dreamed about, what they planned, what they worked on and, most importantly, what came true. After reading the book, you yourself can compare today and yesterday.
