Heinrich Ehrlich is not only a Doctor of Chemical Sciences, a professor at Moscow State University and a serious scientist, but also an excellent scientific popularizer who can talk about very complex things in a fascinating, simple way, without a single formula. Speaking about nanotechnology, he destroys many myths, for example, that these wonderful technologies have only appeared today. In fact, they have been around for at least 250 years, and a lot of interesting things have happened over the years, both in science and technology. This book is about all this, and also about the fates of amazing people, without whom our world today would be completely different.
