A winter break treat from the BBC! They talk a bit about the mathematics of card tricks with one of the few people equally famous among mathematicians and magicians: Persi Diaconis.
To give you an idea what sort of fellow he is, according to Wikipedia Persi supported himself while as a student by playing poker on passenger ships traveling between New York City and South America!
Be sure to catch where Persi mentions that he had our own Martin Gardner as a recommendation letter writer for grad school!
And a nod to Dave Benson for facebooking the BBC interview.
