The first few chapters of this book were written temporarily for the signing of the contract. Later, I slowly finished the full text, which is about 600,000. I will definitely release it. The time is not guaranteed, because I have always had the idea of overturning and rewriting it from scratch...

All names are saved, the introduction needs to be improved, and the full text needs to be revised.
Intention: Everything is done in a practical way
