Something magic happens every time you shuffle a deck of cards—you've come up with an ordering of cards that is unique in all of human history—unless there's a magic trick at work.

In this video, I show an astounding magic trick performed by my friend Shiloh Ahlstrand, who is a professional magician, that has to do with shuffling cards. Then, I show you how to calculate the probability that every time you shuffle cards, the ordering is unique in all of human history.

Thanks to Shiloh Ahlstrand for performing the magic trick and suggesting to me this video.
