At the end of an overnight flight from San Francisco to New York is hardly the ideal time to play “I Spy Mathematics” on a packed airplane. We were all grumpy and groggy from four scant hours of sleep. It seemed that nobody had watched any films en route and, like most of the other passengers, I didn’t have headphones or earplugs to hand.

Clearly there was no point in scanning the entertainment offerings with just 15 minutes to landing. But then I remembered spotting an ad on screen for The Great Courses as I’d settled into my seat in San Francisco. Was it possible that I’d blown a chance to watch Art Benjamin, David Bressoud, Judith Grabiner, David Kung, James Sellers or Mike Starbird in action? I decided to try to find out.
