'Fermat's Last Theorem' Author Amir Aczel Dies At 65

Mathematician Amir Aczel became an unlikely best-selling author when he published "Fermat's Last Theorem" in 1996. It became the first of his many books that attempted to explain the world of math to non-mathematicians.

Aczel died last month from cancer at the age of 65. Here & Now's Eric Westervelt spoke with Aczel earlier this year about what became his last published book, "Finding Zero: A Mathematician's Odyssey to Uncover the Origins of Numbers." We listen back.
