Fermat's Last Theorem Amir D. Aczel Story of the modern-day mathematician who solved a 300-yr old mathematical puzzle.

Around 1637, the French mathematician, Pierre de Fermat, scribbled a note in one of his books, indicating that he'd managed to solve a famous problem of mathematics, but that the margin was not large enough for him to write his proof.

Ever since Fermat mentioned that he'd solved the problem, mathematicians all over the world attempted to find a solution, knowing that it must be solvable.  It wasn't until 1995 that an American mathematician, with the help of some incredibly advanced number theory worked out by others, managed to find a solution.

Aczel's book is sort of interesting, telling the story of the search for a solution to Fermat's Theorem.  But it contains just enough in-depth mathematical details to allow the reader to get slightly lost along the way.  Still, it's an interesting look into the world of mathematics and the people who labor to advance the field of knowledge.
