"Atoms Wander Round a Crystal" is a Sovietwave Popular Science supplement for an infamous "Kvant" journal, a periodic aimed to inspire Math Olympiads-winning Soviet youth to conquer the observable Universe and beyond. For an adult reader those books are still examples of damn_good_popular_literature (that is, if one can read Russian - I don't think many of them were ever translated). Particularly, "Atoms..." is devoted to diffusion, written by a scientist - and a honorable Physical Chemistry professor at the University I graduated from - who devoted all his career to research of various diffusion phenomena. Magnificent reading! Long overdue in my case.
