What if we used math to do card tricks? 26.04.2023. Presentation of The de Bruijn Card Trick using de Bruijn sequences and linear feedback shift registers. The trick has five audience members cut a deck of cards repeatedly and then take a card each. The mathematician then asks a few questions: “Who had porridge for breakfast?” “Who is holding a red card?” “Is anyone a Pisces?” “Who has a dog called Stanley?”. The answers to these questions are sufficient to allow the mathematician to name the card that each person is holding. Here you find a python script that takes the relevant information ("Who is holding a red card?") and compiles a LaTeX beamer presentation with the five cards the audience members are holding on the title page.
