Listen in to the latest podcast of The Math Factor for an interview with Paul Nahin who is a frequent PUP author. In this segment he is discussing his most recent book Mrs. Perkins’s Electric Quilt. And yes — he has the answer to the question above.

We’re thrilled that The Math Factor had Paul on, and look forward to their upcoming interview with Mythematics author, Mike Huber, too.
