In Spring 2023, mathematicians announced "the hat," the answer to a long-standing open question: Is there a single shape (or "einstein") that can tile the plane but such that no tiling ever has a repeating pattern (that is, an aperiodic tiling)?
In this talk I'll give an introduction to aperiodic tilings and some of the keys ideas in proving "the hat" gives an aperiodic tiling. I'll have plenty of tiles to play with!
