TITLE: What are some of the best book in mathematics for general reader?
QUESTION [10 upvotes]: I am preparing a list for my department library, consisting books of mathematics for general readers. I've included The men of mathematics by Bell, Fermat's last theorem by S.Singh , The man who knew infinity and The equation that couldn't be solved. But I need more books to add into my list. Can anyone suggest a few more, where mathematical development of certain concepts/problems or evolution is described in a lucid manner or contains mathematics which everyone can understand. Many thanks!
