Recording of Mini-MOVES: “Double-crossing Euler” with Barry Cipra

This is a recording of a live-streamed event that took place on Sunday, February 20, 2022.

Appropriate for ages 14 and up.

Leonhard Euler famously kickstarted graph theory in 1736, with a proof that the seven bridges of Konigsberg cannot be crossed once and only once on a tour of the city.  But what if someone wanted to cross each bridge twice (once in each direction, without any U-turns)?  We’ll take a brief tour of graphs that can — and graphs that cannot — be “double-crossed.”
