Ivan stood near the installation, which he knew to the smallest screw. Five years of life went from an idea to its creation. Five long, sometimes painful years of searching, trial and error, which now seem like one moment. There were many scientific disputes about the possibility of its creation, misunderstanding and disbelief on the part of colleagues. Sometimes I wanted to leave everything and forget. And when his idea was unexpectedly noticed and supported, a long and difficult path began from the theoretical justification of the idea itself to practical implementation. And all this time, heated scientific disputes continued, tests of individual nodes and testing of the theory in practice, and finally the construction of a prototype in the strictest secrecy. It took so many years before this miracle of engineering was born, which opened up the opportunity to look into the history of our civilization, about which we know a lot and at the same time so little.
