A dead zero is a special enchanted zero to which nothing can be added. Under no conditions. Ever. The quintessence of non-being.
This book was written to reduce the number of dead zeros in the Universe. And, as usually happens, while doing that, we got carried away—we got too enthusiastic, you could say. So now there are no dead zeros left in the Universe at all. But it’s unlikely anyone will cry over them. We don’t need that kind of foolish non-being here.
