To the people who hate this book, I grant you the freedom of your opinion, but I have to say, "You don't get it!" This isn't a narrative in the traditional sense of the word. Instead, Calvino has taken complex scientific principles and turned them into stories. Its true that there is a certain lack of character development, as the main character is a one-dimensional atomic particle (pun intended), but even so, Calvino makes him(it?) come alive in his tales. The true feature and attraction of these stories are the situation and worlds that Calvino creates. All that being said, I read this in the same day that I read Cosmicomics, which is a prior collections of similar stories featuring the same character (and, I think, a better book overall), and the artist's conceit wore a little thin. However, if you can give these books sufficient time and space(pun intended again), they are truly fun and beautiful.
