## Summary:

- what do the digits of pi, colliding blocks and quantum search algorithms have in common? More than you might expect. Two playful papers, one from 2003 and one from last month, provide the links between them. Together, they connect the worlds of dynamics, geometry and quantum computation, highlighting how even the most abstract math puzzles can have surprising physical relevance.
