TITLE: Are there any books written using dialogues?
QUESTION [18 upvotes]: Last year I read Questions And Answers In School Physics. The book is based on a dialogue between a student and a teacher. A lot of concepts and ideas are seamlessly driven by the dialogue. I found the presentation to be lucid and pedagogical.
I am wondering if there is books with a similar style but for mathematics.

REPLY [3 votes]: The Number Devil: A Mathematical Adventure is for younger readers, ages 11–16 or so.  The main character, Robert, has a series of twelve dialogues about mathematics with the titular Number Devil.  They discuss prime numbers, infinity, the fibonacci numbers, and many other topics.
