Big List of Fun Math Books To be on this list the book must satisfy the following conditions:


*

*It doesn't require an enormous amount of background material to understand.

*It must be a fun book, either in recreational math (or something close to) or in philosophy of math.


Here are my two contributions to the list:


*

*What is Mathematics? Courant and Robbins.

*Proofs that Really Count. Benjamin and Quinn.
