CS professor Craig S. Kaplan has helped prove the existence of an einstein (from the German for "one stone") - a 13-sided shape dubbed "the hat" that can tile a plane infinitely without ever repeating. The discovery, which has been covered in prestigious outlets including The New York Times, Quanta, and Scientific American, is the result of extensive collaboration between a team of "tiling enthusiasts" in Canada, the United States, and the United Kingdom.
