## Two solutions to a tiling problem

##### Abstract:

In 1903, Max Dehn settled the following question: which rectangles can you tile with finitely many square tiles (possibly of different sizes)? In this talk, we'll see two (relatively) modern proofs of his result. The first involves redefining the area of a rectangle in a way that would make a measure theorist's skin crawl, and the second involves something even more sacrilegious: physics.
