The next meeting of the Fayetteville Math Circle will be Saturday, November 7th at 2pm at the Fayetteville Public Library.
One of the most universal applications of mathematics is in the understanding of symmetry and patterns. Tilings are one such example and we often want to understand both the local and infinite behavior of these patterns. For example, you can cover the entire xy-plane with squares, triangles and hexagons, but you can also tile with all three, or add in two rhombuses and a trapezoid and make the collection of pattern blocks. Most tilings you can think of are periodic – they exibit some symmetries. It took us until the 60s to understand that there are some collections of tiles that can cover the entire plane, but never be periodic! Our guest this month is Dr. Edmund Harriss who will lead us through this amazing idea.
