TITLE: A Book of Neat Theorems for Laymen
QUESTION [12 upvotes]: I'm looking for reading assignment ideas for my students.  I'd like them to read up on results in mathematics in layman's terms.  For example, the Monty Hall problem, or Borsuk Ulam as the "Ham Sandwich Theorem".  I feel a good source for the types of things I'd like them to read is this post.  I would have each (group) student do a write up on a particular subject.  Does anyone know of any books that give a list of results that are understandable for a calculus student?

REPLY [2 votes]: $Q.E.D.$ is a cute, compact, little book of proofs easily found at Barnes and Noble.
